The initial data for the development of the technological map are:

• 1. General view drawing (assembly drawing or diagram) of a unit, mechanism or unit;
• 2. Specifications for assembly, adjustment, testing, control and acceptance of the product;
• 3. Characteristics of the equipment, fixtures and tools used
• 4. The complexity of operations.

Rationing of the complexity of operations technological process

For each operation of TP TO and TR, a labor intensity norm must be established. Such a norm is necessary for calculating the number of performers and remuneration for their labor and for designing the technical process (even distribution of the amount of work among the performers, drawing up the optimal sequence of operations, etc.).

The general norm of time for performing operations consists of operational, preparatory and final time, time for servicing the workplace and breaks for rest and personal needs.

Operational is the time spent directly on the execution of this operation. It is determined by one of the methods discussed below.

The rest of the norm of time is set in the form of allowances as a percentage of the operational time.

Thus, the norm of time for the operation TO, D, TR in minutes or hours:

where To - operational time, min (h); A, B, C - respectively, the share of time for preparatory and final work, maintenance of the workplace, rest and personal needs, %. A + B + C = 12.5.

The complexity of operations in man-hours or man-min is found by the formula:

Tn \u003d TV * R * Kp (2)

where P is the number of workers performing the operation, people; Kp is the operation repeatability coefficient, which characterizes the frequency of the operation during maintenance (D, TR).

For example, control and diagnostic operations are performed without gaps (mandatory for each service Кп=1). Adjusting and fastening operations may have Kp< 1, т.к. после проверки, если adjusting parameter normal or tightening of the fastening connection is not required, they can be skipped. The repeatability coefficient depends on the reliability of the vehicle design and the quality of the previous MOT or TR, varies for various operations, approximately within Kp = (0.2-1), and is determined by processing the relevant statistical data or according to standard MOT and TR technologies.

The complexity of maintenance and repair operations can be set in one of three ways:

• - using ready-made standards from standard technologies and standard norms of time for maintenance and repair of vehicles;
• - data processing timing observations for their implementation;
• - microelement regulation of operations.

The simplest and most desirable is the first method.

Standard norms of labor intensity are accepted according to

Typical norms of time (labor intensity) are subject to certain operating conditions. If the actual conditions for performing operations (other equipment, level of mechanization) differ from the average conditions specified for standard standards, they should be adjusted for the conditions of the designed process. So, for example, with the in-line method of organizing service, the standard labor intensity can be reduced by 15–25% of the typical norm. If the conditions for performing the operation differ sharply from the typical ones (new equipment, new vehicle design), then the labor intensity standard is set in other ways.

Timing observation method

The method of chronometric observations gives the most accurate results, but it is very laborious and requires a long time to establish the complexity of operations due to the large number of observations and the complexity of processing the data obtained. Let us briefly consider the main provisions of the method of time-keeping observations.

For timing, the performers of maintenance and repair work are selected in a special way (work experience, qualifications, age, etc.).

Timing is carried out at certain hours of the working shift (one hour after the start of work, stops one hour before lunch or the end of the working day).

The number of timing observations should be sufficient to reliably determine the average TO. Their minimum number is determined according to table 2, depending on the duration of the operation and the way the work is performed.

Table 2 - Required number of measurements during timing

Timing data are arranged in a variational series (from min to max). The stability and stability of the results of observations is checked by comparing the actual value of the stability coefficient of the chrono-series with its normative (table) value (Table 3).

Table 3 - Normative value of the coefficients of stability of the time series

The stability coefficient of the chronological series is found by the formula:

where t max, t min are the maximum and minimum values ​​from the composition of the time series. A chronological series is considered stable if the actual "stability coefficient is less than or equal to the standard one: K Kn.

If this ratio is not observed, then the observations should be repeated. As an exception, due to the high cost of timing, it is allowed to correct the time series by discarding its extreme values ​​(t max, t min).

The operational time in minutes to perform the operation is found as the average value of the members of the chronological sequence:

where ti is the value of the chronological series members , min; n is the number of members of the chronological series.

Timing and setting the norm can be carried out only after the introduction and debugging of a new technological process, i.e. it is impossible to design the norm of time (labor intensity) of operations at earlier stages of the development of TP.

Microelement method for designing normative complexity of operations

Microelement systems are currently widely used to determine the labor intensity of TP operations.

The essence of this method is that the most complex operations can ultimately be represented as a certain sequence of repeating simple elements, for example: move, install, fix, connect, etc. (Table 4).

If we divide the normalized operation into a number of such microelements and sum up the time available in the database for their execution, then we can find the operational time to complete the entire operation.

The main advantage of this method is the possibility of designing labor intensity norms "at the table" at the stage of TP development, which significantly reduces time and costs in comparison with the method of chronometric observations. Of course, this is possible with great experience and qualifications of process engineers (knowledge of the design of a given brand of car, the operation and capabilities of the technological equipment, fixtures and tools used, etc.).

The time values ​​for the execution of microelements of the operation are “clean”, i.e. with their convenient implementation and free access to the service point. In real conditions, the convenience of performing work (working postures, table 4) and access to a service point (table 5) for each brand of car and operation will be different, therefore, in the operational time for the operation to be corrected by the appropriate coefficients.

Thus, the general equation for normalizing the labor intensity of car maintenance in man-min or man-hours with this method looks like this:

Tn \u003d (t1 + t2 + ... + tn) * K1 * K2 * (1 + (A + B + C) / 100) * P * Kp (5)

where t1 is the time to complete the microelements that make up the operation; n - the number of trace elements in the operation, incl. and taking into account their repetition; K1, K 2 - respectively, the coefficients taking into account the increase in time to perform the operation due to the deterioration of convenience and access during work (Tables 5 and 6); P is the number of executors of the operation; Kp - operation repeatability coefficient for maintenance and TR; A, B, C - allowances in% of the operational time.

Microelements are understood as elements of operations, consisting of labor movements of the worker. It has been established that any physical work includes: movement of arms, legs, inclination and rotation of the human body, transitions, i.e. an unchanging series (set) of repetitive movements.

One of the systems of microelement standards is the system of "standards" of Professor V.I. Ioffe. In this system, any element self made consists of a combination of two trace elements: take and move (combine, move, install, remove).

The degree of fragmentation of operations into microelements is of fundamental importance. The division of operations into elementary movements makes it possible to obtain a universal base of microelements suitable for designing labor intensity standards for any technological process. However, at the same time, the accuracy of determining the time for the implementation of microelements (hundredths and thousandths of a minute) falls; the process of synthesizing an operation from elements becomes more complicated. Big mistakes are possible.

Given this provision, at this stage, based on the collection and synthesis of information on literary sources and regulatory and technical documentation, etc., a base was developed in the amount of 44 microelements (table 4).

With the enlargement of microelements, their versatility decreases, since the probability of repetition in a large number of various operations and processes decreases. But it simplifies the process of designing operations in which they occur. Therefore, in our opinion, the base of microelements for TP TO and TR of cars should consist of two parts. The first part should contain elementary movements encountered in the operations of any labor processes. The second part - larger elements of operations of specialized maintenance and repair works (fastening, welding, etc.).

The base of trace elements presented in Table 4 is not sufficient, it needs to be improved and expanded. With its help, it is possible to design, mainly, the labor intensity standards for control, diagnostic and adjustment operations of maintenance and repair of cars, however, it allows us to demonstrate the possibility of the method under consideration.

The labor intensity and complexity of the work are largely determined by the characteristics of the object of labor. A car is a complex object of labor in its maintenance.

Process impact points (sometimes called service points) are located on the side, bottom, and top of the vehicle. Therefore, when servicing a car, first of all, it is necessary to provide performers with access to service points. To reduce service time, it is better to provide simultaneous access to several workers from all sides.

In addition, it is necessary to provide the performer with the least fatigue and the greatest safety during work. Research has established that fatigue, and hence the productivity of a worker, significantly depends on the working posture he occupies. Table 5 shows data on changes in labor productivity depending on the working posture.

The conditions for performing operations directly in the area of ​​service points are characterized by their availability, which also significantly affects the labor intensity of the work. The impact of access to places of technological impact during maintenance and repair of a car is presented in Table 5.

GENERAL PART

This collection contains typical schemes technological processes for maintenance (TO) and current repairs, (TR) of the contact network of direct and alternating current and points for grouping docking stations. The list of technological maps of the collection corresponds to the scope of work of Appendix 5 to the "Rules for the design and technical operation of the contact network of electrified railways"" (PUTEKSCE-197).

The collection is intended to guide the organization and performance of work. Technological maps provide for the performance of work by personnel of contact network areas (ECC) and specialized teams of repair and inspection sites (RRU) of power supply distances (EC) equipped with vehicles, mechanisms, devices and main mounting devices, provided for in Appendix 4 to PUTEKS TsE-197. The maps reflect the current level of engineering and technology, organization of production and labor in the performance of work on the contact network, the components and structures of which correspond to standard projects and PUTEX.

The development of technological maps is based on:

Typical time limits for maintenance and Maintenance contact network of electrified railways (Moscow, Transizdat, 1995).

Technological maps for work on the overhaul and current repair of the contact network (Moscow, Transport, 1973).

Device rules and technical operation contact network of electrified railways, TsE-197 (Moscow, Transport 1994).

Collection of technical instructions and information materials on the economy of power supply (Moscow, Transizdat, 1996).

Preventive testing of power equipment of traction substations. Collection of guidelines (Moscow, Transport, 1967).

Instructions for the protection of railway underground structures from corrosion by stray currents, TsE-3551 (Moscow, Transport, 1979).

Guidelines for the maintenance and repair of contact network support structures, K-146-96 (Moscow, Transizdat, 1996).

Instructions for grounding power supply devices on electrified railways TsE-191, (Moscow, 1993 p).

Faults and deviations from the established norms revealed during the maintenance or repair work, which can cause interruptions in the movement of trains, power outages or violating safety requirements, must be eliminated immediately, about which the work manager must report to the power dispatcher and then be guided by his instructions. Their implementation is carried out according to the relevant Technological maps and is additionally standardized, and in the absence of time standards - according to actual costs.

The technological maps define the categories of work in relation to safety measures, set out the basic requirements to ensure the safety of personnel when performing work in accordance with the "Safety Rules for the Operation of the Contact Network of Electrified Railways and Automatic Blocking Power Supply Devices", TsE / 4504 (Moscow, Transport 1988 .) and "Safety instructions for electricians of the contact network", TsE / 4816 (Moscow, Transport, 1992).

The cards indicate the sequence of operations that ensures the safety of personnel. The sequence must be strictly observed when performing work. The composition of the performers and the norms of time correspond to the "Typical norms of time for maintenance and current repairs of the contact network of electrified railways", approved by the Ministry of Railways of the Russian Federation on 06/07/95.

The composition of the performers does not include signalmen for fencing the place of work. Their number is determined by the "Instruction for ensuring the safety of train traffic during work on the contact network from insulating removable towers", TsE / 4373 (Moscow, Transport, 1987), taking into account local conditions and is specified in the work order. The number of signal accessories and portable radio stations required for them is not provided for in section 3 of the technological maps and is determined additionally.

In * a number of technological maps (for work not included in the collection of Model Time Standards) time standards are indicated, adopted on the basis of statistical and calculated data. In the future, it is planned to develop technically justified time standards for these works.

The time standards given in the technological maps take into account only operational time and must be adjusted in accordance with the instructions of the general part of the "Typical time standards for maintenance and current repairs of the contact network of electrified railways" (Moscow, 1995!). The performance of additional operations during the TS that are not provided for by the technological map is normalized according to the actual costs.

It is allowed to combine several works, if the composition of the performers, their qualifications and the category of work in relation to security measures are the same in the technological maps for these works. In these cases, the time limit for performing combined work must be reduced by multiplying by K \u003d 0.925 - when performing work from an isolating removable tower and by K \u003d 0.936 - for work without an isolating tower.

When driving, pay special attention to: The position of the supports (tilt and deflection are not allowed), the reliability of their fastening in the ground (there should be no subsidence, landslides or soil erosion near the supports), serviceability of the grounding; Compliance of the position of the clamps with the air temperature or technical standards, the distance between the contact wire and its main rod, the lower fixing cable or fixing guy (it is unacceptable to reduce this distance - preload), the serviceability of inclined strings or rigid struts, as well as lift limiters; The magnitude of the sag of the longitudinal wires and their relative position, the preload of the wires to the grounded structures, the presence of dangling wires, the sagging of the wires of the middle anchorings or the anchoring branches of the mates of the anchor sections; The condition of the insulators, the presence of damaged insulating parts or the presence of bending of the connecting fittings, as well as the preload of the suspension insulators of the garlands to grounded structures; The condition of the compensatory devices (breaks in the cores of the cables are not allowed, the distances between the blocks, as well as from the bottom of the compensator weights to the ground and from the top of the cargo bar to the fixed compensator block must correspond to the air temperature); The condition of the cable and strings (breaks of strings and cores on the cable are not allowed, the slope of the strings along the path should not exceed 30 ° to the vertical); Condition and adjustment of arresters, sectional insulators, air arrows; Condition of disconnectors, loops and drives; The presence of mechanical vibrations ("dancing") of the wires of the contact network; Interaction of pantographs of oncoming trains and contact suspension along the adjacent track; The voltage level on the instruments in the driver's cab. Sharp fluctuations of the kilovoltmeter needle during movement indicate a violation of the current collection. 6.1.2. Inspection results l all identified deviations from technical standards record in a notebook indicating their location (name of

		rut or station, track number, support, span, etc.). 6.1.3. If deviations are detected that can cause disruptions in the movement of trains, take measures through the energy dispatcher to eliminate them, organize the passage of trains at this place with the pantographs lowered or with a speed limit.
