Design of ATP for 250 ZiL-431410 vehicles

Introduction

The quality of reconstruction, expansion, technical re-equipment and new construction is largely determined by the quality of the relevant projects, which should meet all modern requirements for capital construction. The main requirement is to ensure a high technical level and high economic efficiency of the designed enterprises, buildings and structures. To meet these requirements, it is necessary to maximize the use of the latest achievements in science and technology so that new or reconstructed ATPs in terms of the time of their commissioning are technically advanced and have high indicators in terms of productivity and working conditions, level of mechanization, cost and quality of production, and efficiency of capital investments.

The task of increasing the efficiency of capital investments and reducing the cost of construction is part of the problem of rational organization of road transport and covers a wide range of operational, technological and construction issues.

The solution to this problem is primarily ensured by high-quality enterprise design, which largely determines the rational use of fixed assets and high efficiency of capital investments.

The main prerequisites for high-quality design are:

- proper justification of the purpose, capacity and location of the enterprise, as well as its compliance with the progressive forms of organization and operation of road transport;

- production cooperation with other enterprises, centralization of maintenance and maintenance of rolling stock;

- selection of land plot taking into account co-operation of external engineering networks;

- unification of space-planning solutions of the building using the most economical prefabricated structures, standard parts of industrial manufacture and modern building materials.

2 technological calculation of zones t and t

2.1 Selection of the method of maintenance and maintenance of cars.

For TO-1 zone, we accept dead end universal posts, since the number of daily services is 8

For the TO-2 zone, we also accept dead end universal posts, since the number of daily services is 3

2.2 Substantiation of operation modes of zones and sections

According to the task, rolling stock works 244 days a year (5-day work week), one shift, therefore, we accept a 5-day work week for production workers, while the number of shifts is selected from the recommendations in according to Table 6/6/, c = 2. The shift duration is 8 hours, since the company works 244 days, and the annual working time fund is 1923 hours.

3.2 Justification of room composition

Selection of room composition is performed after calculations of labor intensity and posts of zones and sections. According to the task, the layout of the EO zone is pavilion, that is, it is located in a separate building. Maintenance and maintenance zones, areas are located in the same production building. Welding, tighter and reinforcement, electrical, battery and power system works, busbar and vulcanization works are combined into one section, since the number of workers turned out to be less than one. D2 diagnostic post, welding, woodworking and painting posts are located in isolated rooms .

4.1 Process of works execution in mechanical and locksite area.

The area is intended for repair of parts of locksmith machining, as well as manufacturing of some parts of non-goods nomenclature (additional repair, simple axes, shafts). Basic parts (cylinder blocks, front axle beams, crankcase) in this area, as a rule, are not repaired.

These works are carried out by 2 people, work is carried out in one shift.

The department is equipped with drilling, milling and turning-screw-cutting machines, racks, tools and devices.

5 layout of the production building

5.1 Space-planning solution of the industrial building

cases

When designing the production building, we accepted the dimensions of the building taking into account the need for layout of zones and sections, the necessary width of the passage, as well as the need to accommodate storage and auxiliary rooms. The total design area of the production building is 3020m2. According to the assignment for the zone EO-pavilion layout, that is, it is located in a separate building. Then the area of ​ ​ the production building, where the maintenance and maintenance zones are located, will be approximately 1750 m2.

We accept 2 spans of 18 m, then the width of the building will be 36 m.

We determine the length of the building 1750/36 = 48.6 m, we take the length as a multiple of 6 m, i.e. 48 m.

When selecting the column grid, we took into account the recommendations/5/, according to which for ZIL vehicles the column grid is accepted 6 * 12 when for the maintenance and TR zone we take the step of 12 m. A crane-beam is provided in the designed building

above TR zone, span height is 7.2 m (Table 46 ,/5/). The adopted height of the room provides the necessary working conditions.

When designing posts, we use inspection ditches. When choosing the distance between the posts, the car and the wall, we took into account the requirements given in Table 7.9 ,/2/. The distance between cars of category 2 is 2.5 m. The distance to the wall is 1,8 m.

5.2 Layout of production and storage facilities

The layout of the production and storage rooms in the building was carried out in accordance with the repair process. For example, work on D-1 and D-2 is carried out respectively before TO-1 and TO2, therefore, D-1 post is located next to TO1 post, and D-2 post is located in a separate room and has free passage at TO-2 posts.

The TP area is closely connected to all production areas by the nature of the production impacts, so we located them in the central part of the building.

Welding, reinforcement and copper sections belong to the group of hot workshops, and have a small production program, so we combined them into one section. The bus assembly and vulcanization sections are combined into one section, since the production program is small and next to the TR station, and the tire warehouse is next to this section.

All production, storage rooms have a message between them. Rooms for lubricants and paint are located near the areas used, i.e. near the maintenance area and the painting post, respectively.

5.3 General Layout of the Production Enclosure

After choosing the final layout of the production building, the planning solutions of individual zones and compartments are finalized. In the drawing of the production building, we apply production and storage rooms with a schematic image of the walls and partitions of the building, columns, inspection ditches, etc.

In the drawing, we also apply the overall dimensions of the building, the dimensions of the pitch of the columns and spans, as well as the coordinate grid for the columns.

Conclusion

During the course project, the task of designing ATP for 250 ZIL431410 cars and the technological layout of the locksmith and mechanical section was solved. To organize maintenance and maintenance in this ATP, during the operation of the 1st category under the condition of operation, 44 production workers, 19 work posts and 5 waiting posts will be required. To place zones and sections, a production area of ​ ​ F = 3020 m2 and a building with dimensions of 48 × 36 m are required. To place a locksmith-mechanical section, 30 m2 of area with dimensions of 6 × 5 m is required. The resulting calculated values ​ ​ when compared with standard values ​ ​ give a deviation within the tolerance, which confirms the correctness of the decisions made in the project .
