Introduction

The features and advantages of road transport, predetermining its advanced development, are related to the mobility and flexibility of delivery of goods "on time." Road transport plays a significant role in the transport complex of the country, regularly serving almost 3 million enterprises and organizations of all forms of ownership, peasant and farm farms and entrepreneurs, as well as the population of the country. The main advantage of road transport over other modes of transport is its low cost.

The main tasks for the ATP technical service are:

- maintenance of serviceable condition of rolling stock.

- ensuring reliability and cost-effectiveness of performed works.

- reduction of vehicle technical condition deterioration intensity, number of failures and faults.

Performance of works on TR of cars prevents possible malfunctions. In case of vehicle breakdowns and faults, repairs are provided, which are performed as required in case of faults.

Objectives of the course project:

- systematization, fixation and deepening of thermal knowledge obtained during the study of the subject.

- assimilation of basis of design and technological calculations of TR zones and repair areas at ATP.

- the ability is correct to choose a method of the organization of production TO and TP and its justification for specific conditions.

- the ability to use technical and regulatory reference literature.

Design Object Characteristics

General Farm Information

OOO Avtotorosgaz has been operating since March 1, 1999, OGRN was assigned on September 24, 2002 by the registrar of the Interdistrict Inspectorate of the Federal Tax Service No. 15 in the Nizhny Novgorod Region. Head of the organization: General Director Podanovich Oleg Borisovich .

The legal address of OOO Avtotrosgaz is 607910, Nizhny Novgorod Region, Pochinkovsky District, the village of Pochinki, Sidorova Street, house 145 building A. LIMITED LIABILITY COMPANY AVTOTOTSGAZ is assigned TIN 5227003301, OGRN 1025200912472, OKPO 50688585.

Primary activities: rendering motor transportation services, processing of transport cargoes, warehousing and storage of cargoes, performance of work on clearing of routes from wood and shrubby vegetation, arrangement along route drives, repair of knots, units, furgonovkung, diagnostics and repair of SDT.

The goals and objectives of society.

Characteristics of car service facilities

Cars can be stored indoors and in open areas. When organizing the storage of cars, the following conditions are met:

1. Cars that must be constantly ready for immediate departure are stored in heated rooms;

2. Cars are stored indoors;

4. Depending on climatic conditions, trucks can be stored in closed rooms, under canopies or in open areas;

Geometrical dimensions of parking lots for cars are determined by number of storage places, overall dimensions of cars and method of arrangement, sizes of passages between vehicles, distances between cars and building elements and width of passage in parking lot. Air temperature in heated premises for car storage in winter shall not be lower than + 5 ° С. For vehicles that are stored in open areas, it is necessary to provide facilities to facilitate the start of the engine in the cold season, and rooms for heating cars before they are received for maintenance or repair.

Platforms for car storage are located in dry, non-heated places with a flat surface and a slight slope for rainwater and meltwater. They are equipped with drainage ditches and snow retention devices. The platforms are made rectangular and placed so that the direction of the dominant winds is along the rows of cars. To better protect against snow drifts, trees and shrubs are planted. For convenience of maintenance, the distance from cars stored on the sites to the walls of buildings should be at least 10 m, and to the fire walls of buildings or to the fence of the site - at least 2 m.

The central repair shop, OOO Avtotorosgaz is located in the central part, where the entire machine fleet is concentrated. CRM is intended for carrying out maintenance and maintenance of trucks, cars, tractors, special equipment, buses, trailers, p / trailers, units and knots of cars.

This central repair shop can service a machine fleet of 25 pcs. Total workshop area 874 m2

The CMM includes the following areas and rooms:

Mechanical and forge welding areas

Battery charging and storage area

Power equipment repair area

Busbar and vulcanization

Repair and installation

Fuel equipment repair area

Engines repair area

Masters Room

Workshop Manager's Office

Conclusion

In this diploma project, the production program for the maintenance and repair of rolling stock was calculated for the total total labor intensity of maintenance and maintenance, the number of workers was calculated, the costs of the enterprise for the implementation of the production program for maintenance and maintenance of rolling stock were calculated, and the area of ​ ​ the site was calculated.

The technology for restoring the piston-rod group of ICE has been developed.

In the design, a universal device is proposed, for pressing out and pressing out the piston pins and sleeves of the connecting rod head, the bolt is calculated for strength, the plate is calculated for bending under the influence of the bolt tightening force, and the elements are built.

In the economic part, the cost of repairing the technological process of repairing the part was calculated.

Regulations on safety, electrical safety, fire safety and environmental protection at the harvesting site have been developed.

In the section, labor protection indicates the main production hazards and optimal meteorological conditions on the site.

As a result of the diploma project, I consolidated the knowledge and skills gained during the training process, in the organization of maintenance and repair of cars, and also gained design skills.
