Introduction

Road transport is essential in the national economy. Recently, the number of cars has increased, both among the population and the number of vehicles used in the national economy.

In this regard, it is necessary to expand and improve the repair base. This should be done with the help of the latest technological developments of both domestic and foreign design bureaus for the repair of vehicles.

So if you provide high-quality and reliable repair of parts, assemblies and assemblies at minimum costs, then not small funds, the number of spare parts and time are saved. At the same time, the reliability of vehicles is increased.

The need and expediency of repairing cars are primarily due to the unequal strength of their assemblies, assemblies and parts. Therefore, the repair of a car, even by replacing some of its parts, assemblies and assemblies with a small resource, is always feasible and economically justified.

Therefore, during operation, cars undergo periodic maintenance (TO1, TO-2) and, if necessary, ongoing repairs (TR), which are carried out by replacing individual units, parts or units that have failed to operate. This allows you to maintain cars in a technically serviceable state.

In modern economic conditions, there is a certain demand for transport services. In this regard, it becomes profitable to create car enterprises with their own repair base. 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.

The purpose of course design is to systematize and consolidate the theoretical, practical and special knowledge acquired during the entire period of study in the specialty "Cars and automotive economy."

2.2 Space-planning solutions of the production building

The obtained results of the accepted space-planning solutions of the production building and area TO1are presented in the graphic part of the project on the sheets "Production building" and "Production section."

2.3 Construction Part

For ATP buildings, it is recommended to use reinforced concrete columns with dimensions of 400 × 400 mm; 500 × 500 mm and 500 × 600 mm depending on their pitch span and room height.

It is advisable to use prefabricated reinforced concrete coating structures: beams with a span of 12 m, construction trusses - 18. 24. 30 m, large-panel reinforced concrete and ceramic concrete slabs of coatings 3 × 6 and 1.5 × 6 m. For the walls of buildings, reinforced concrete and concrete panels with an insulation of thickness 25 cm, height 0.8 are used; 1,2; 1.8 m and 6 m wide. In the absence of such panels, brickwork should be used. The thickness of the brick walls, depending on climatic conditions, is 38, 51, or 64 cm. The internal partitions can be brick or plaster 10 and 12.5 cm thick, as well as metal mesh. Partitions, as a rule, are installed along the columns.

In production and storage rooms, single-floor doors 1 m wide and double-floor doors 1.5 and 2 m wide are used. Their height is 2.4 m. If a monorail passes through the door opening, then their height increases.

The dimensions of the window openings shall be a multiple of 500mm in height and 1000mm in width (in some cases the width of the window opening may be 1500mm). In the production building, the dimensions of the openings of the gate must be taken (width by height) 3 × 3; 3,6×3; 4×3; 4х3.6; 4 × 4.2 m depending on the overall size of the rolling stock and the conditions of entry.

2.4 Development of planning solution of zone or section

The graphical part of the maintenance area or area design is performed on a scale of 1:25, 1:50, or 1:100.

The area (area) layout drawing should be placed on the sheet as it is located on the layout of the production building.

Maintenance posts, equipment and accessories of maintenance zones, TR and sections are indicated on the layout by overall dimensions. Arrangement of equipment is carried out taking into account the norms of its placement.

The drawing shows the dimensions of the zone (section), the overall dimensions of the equipment, the dimensions of the equipment binding, the schematic symbols show the workplaces, consumers of electricity, water, steam, compressed air, etc.

The process layout of the production site is a plan for the placement of technological equipment, production equipment, lifting and transportation and other equipment and is the technical documentation of the project according to which the equipment is placed and mounted.

Process equipment includes stationary and portable machines, stands, appliances, accessories and production equipment (milestones, racks, tables, cabinets, etc.).

We carry out technological layout of busbar and vulcanization sections.

As recommended, we accept the following equipment for these areas:

busbar section:

pneumatic spreader;

tire pumping stand;

stand for wheel discs editing;

tyre removal bench;

wheel discs painting chamber;

single-tier rack for tires.

vulcanization site:

verstak with clutches;

Waste lar;

wall hangers for cameras;

electric vulcanizer for repair of chambers;

a bath for checking the cameras;

rough machine;

hand-held glue tester.

Tool and Materials:

Pneumatic Special Tool:

roller with a maximum number of 4000 rpm (for rubber treatment);

cutter with a maximum number of 16,000 sound20,000 rpm (for metal cord processing );

pneumolobic (for metal cord removal during sidewall treatment);

pneumomolets (for working with metal cord patches);

ejection vacuum cleaner (to remove rubber dust from the treatment area);

tread cutter (for restoration of drainage paths after vulcanization);

manual tool (only list of required groups is given):

manual tool for repair of chambers and tires - introductory seams, pins, shroud knives, touching rollers, screwdrivers for spools, etc.;

abrasive tool - various cutters for processing channels when installing fungi and plugs, contour wheels for treating the outer and inner sides of the tire, cutting discs and cones for removing and treating the cord, grinding wheels, as well as adapters and adapters for quick change of the tool during operation;

abrasive tire repair materials.

The equipment of this section allows for high-quality installation and dismantling of all types of wheels of cars with a disk diameter of 11-20 inches, as well as repair all types of damage on chamber and tubeless rubber, including damage to the tread, shoulder and sidewall, with damages not exceeding the maximum permissible .
