1. general provisions

1.1. Importance of motor transport and maintenance in the national economy of Ukraine

In the national economy of Ukraine, road transport is of great importance. The car nowadays has a massive distribution. No area of ​ ​ the national economy can do without road transport.

Transportation of goods and passengers as urban and long-distance transportation. Provides the export of agricultural goods to the railway, sea and annual transport, transport services for enterprises in urban, intercity and international transportation - this is far from a complete list of tasks and capabilities of mobile transport cars. The lack of a developed railway network and the limited ability to use rivers for navigation make the car the main vehicle.

An important area of ​ ​ development of the national economy of Ukraine is an increase in freight turnover of road transport and passenger turnover of bus transport.

The annual increase in road transport in Ukraine will cause a significant increase in the set of enterprises for maintenance and repair of road transport and requires more qualified personnel.

To cope with a large amount of work to support the car fleet, which is constantly increasing in a technically serviceable state, it is necessary to mechanize the maintenance and maintenance processes of cars.

1.3. Justification of initial data

In the assignment for the course project, it was set to develop a battery department, which is located in Nikolaev. The rolling stock consists of cars MAZ6422, and KRAZ258V1. Cars of the MAZ6422 brand make up the predominant majority and therefore are taken as the main brand, their number is 138 units with an average daily mileage of 177 km. The number of KRAZ258V1 cars is 105 units with an average daily mileage of 184 km. In total, the designed ATP has 243 units of rolling stock, which is operated according to 3 categories of operating conditions.

Design Part

During the operation of the battery, there is a need for its maintenance, namely, checking the electrolyte level, electrolyte density and voltage on the electrodes. When adding or completely replacing the electrolyte, it is necessary to monitor the level in each can, and it should be 1015 mm higher than the upper edges of the plates.

The task for the design part of the course project was to develop an accessory for adding electrolyte.

It is a vessel that automatically stops the supply of liquid after reaching the normal level in the battery.

The assembly drawing of the accessory is presented on the A2 sheet of the graphic part of the course design.

The main parts of the device are: vessel; drain pipe; air tube; traffic jam.

During the addition of electrolyte, this device allows to withstand the required level of electrolyte in the accumulator. Since the level should be 1015 mm higher than the plates, the air tube is shorter than the drain tube just by this distance.

Description of the work organization of the designed division

5.1.Organising structure of ATP

Improving the organization of maintenance and maintenance of rolling stock is one of the important tasks that is being solved to increase the efficiency and quality of the work of vehicles, increase the productivity of work. The Regulation on Repair and Maintenance of Vehicles established that the basis of the technical policy is a planned preventive maintenance system and repair of units using a conditional method, which production subsections are purposefully created according to the technical principle with centralized control .

The system with centralized management of maintenance and repair of rolling stock provides for: centralized management of production subsections; formation of production subsections according to the technical principle, in which each type of technological influence is performed by special subsections; unification of production subsections performs homogeneous work in the production complex; reinstatement of units, assemblies and mechanisms removed from the car by the mechanized production preparation complex; Exchange of information between the department.

5.2. Organization of labor protection

Safety precautions are a system of organizational and technical measures aimed at preventing harmful and hazardous industrial factors that can lead to injury.

Industrial sanitation is a system of organizational and hygienic measures that prevent the impact on working production factors that can lead to diseases.

At production enterprises and in construction organizations, responsibility for the implementation of the entire set of labor protection measures is assigned to the director (head) and chief engineer. Health and safety engineers are involved in large enterprises. In small enterprises without such a position, direct control is assigned by order of the director (chief) to one of the engineering and technical workers.

Compliance with safety and industrial sanitation regulations is mandatory for both the performers and the administration.

Instruction is one of the mandatory measures that ensure the safety of work during maintenance and repair of machines.

To prevent harmful effects of aggressive detergent liquids on the human body, it is necessary to ensure regular washing of hands, the use of individual protective equipment - rubber gloves, boots and other special clothes.

Lubricant and working fluid are combustible viscous liquid - 280 ° С. It is forbidden to handle open fire, lighting must be explosion-proof.

The locksmith tool must be securely fixed in the handles, the working surfaces must have no damage. Use wrenches as per GOST. The size of the keys must match the size of the nut. When working with a metal cutting tool, workers must wear safety glasses and use protective equipment. Only workers who have undergone special training are allowed to work with manual machines.

Maintenance of machines shall be performed only after engine shutdown and pressure relief in hydraulic systems.

Before disassembling and assembling machines, the workstation must be cleaned from

foreign objects, prepare racks, accessories and

lifting means. Lifting devices and their load-lifting devices shall have passports indicating the maximum lifting capacity to be subjected to periodic tests and examinations.

Disassembly and assembly of machines should be performed in the sequence specified in Job Instructions or Instructions for disassembly and assembly of this machine.

Special care should be taken when working on grinding and drilling machines. The grinding machine must have a casing that reliably protects against injury when the sandwich wheel breaks. If the sharpening machine does not have a screen, it is necessary to use glasses that protect the eyes from abrasive dust. It is forbidden to move the handcuff during operation of the machine.

During painting of parts or machines using pneumatic tools, all unauthorized persons shall be removed. Air pressure during painting shall not exceed 0.2MPa. Nitroemals, as well as their solvents, are flammable; therefore, it is strictly forbidden to smoke and use open fire when painting. Plenum ventilation shall be operated in the painting room. Hoses are fixed on connectors of painting devices with clamps.

Fire safety shall be ensured by fire prevention and fire protection systems. During repair, it is forbidden to take open fire in all rooms, and smoke in places not reserved for this. It is necessary to remove combustible waste and garbage in a timely manner, strictly observe all operating rules of the equipment and check the condition of the wiring.

Production rooms shall be equipped with fire alarm, necessary fire fighting equipment and facilities. Within the site where the machines are maintained, it is necessary to place fire stations equipped with service fire equipment - shovels and boxes with sand, bagels, buckets and fire extinguishers. In stationary rooms, cranes and shields should be provided.

A poster indicating the telephone to call in the event of a fire should hang near each post. Each employee is obliged to inform the relevant fire brigade by telephone about the occurrence of a fire center and to engage in extinguishing the fire center with improvised means before the fire brigade arrives.

Do not:

In the battery charging room, to avoid explosion, light fire, smoke, use electric heating devices (electric tiles with an open spiral, etc.) and allow sparking of electrical equipment;

allow unauthorized persons into the premises of charging and acid;

connect the battery terminals with wire;

check the battery by short circuit;

pouring molten lead into wet molds and putting wet pieces of lead in the molten mass;

pour water into the acid, since "boiling" occurs and electrolyte spilling out of the vessel is possible;

Store in the repair and charging compartments storage vessels with sulphuric acid and alkali in an amount exceeding the daily demand, as well as empty receptacles, which should be stored in a separate room;

jointly store and charge acid and alkaline batteries in one room;

take in the accumulator food and store drinking water there in order to prevent harmful substances from entering into them from the air;
