Description

SELF-PROPELLED WELDING COMPLEX

The proposed utility model relates to a specialized integrated vehicle on the chassis of an electric vehicle or small-sized car.

At present, to carry out welding work in the field (for example, in public utilities and in construction), transported by various means of transport or towed trailed welding units are used. As a vehicle for transportation of the welding unit by road, vehicles of sufficient capacity, electric vehicles or trailers equipped with a cargo area are used. To tow a welding machine on a trailer or a towed trailer-mounted welding machine, vehicles that develop sufficient traction, cars, electric cars and tractors are used.

Currently used vehicles and methods of transportation of the welding unit have a number of disadvantages that reduce the efficiency and economy of the welding work performed, namely:

- cars used for transportation of the welding unit in the body have a carrying capacity of 1500 kg or more, the weight of the welding units does not exceed 1000 kg. For example: ADD-3119U1 has a mass of about 830 kg, ADD-3123U1 - about 720 kg, ADD-4004 - about 830 kg (according to the passport DSHIB.561311.001 PS, DSHIB.561311.004 PS, DSHIB.561311.005 PS). At the same time, trucks are used with incomplete loading, which leads to unjustified excessive consumption of fuel;

- the truck during transportation of the welding unit is distracted from performing other transport operations or is idle when performing welding operations;

- the driver is distracted from performing other transport operations of the truck or is idle when performing welding, but this time requires payment for his labor;

- loading the welding unit onto a truck requires a crane, which leads to the diversion of lifting equipment from performing other work, wasteful fuel consumption, wasteful use of resources, and the creation of dangerous working conditions when carrying out lifting operations;

niya additional two people: crane operator and sling and requires payment for their labor;

- when loading a truck with a crane, work sites or transport routes are unnecessarily cluttered for a while for equipment that does not directly provide welding work, which affects working conditions and the safety of work;

-installation of the welding unit on the truck’s chassis also leads to uneconomical fuel consumption, to the use of a vehicle with incomplete loading and for unusual purposes, a possible miscellaneous sort of fuel and lubricants, unjustified increase in the dimensions of the installation, increase in the area of the parking lot and storage;

-when transporting the welding unit in the trailer body, trucks or tractors with sufficient traction are used, but at the same time there is an excessive consumption of fuel for transporting the mass of the trailer and the mass of the towing vehicle;

- a vehicle used to tow a trailer is distracted from performing other transport operations or is idle when performing welding operations;

- the driver of the towing vehicle is distracted from performing other transport operations, but this time requires the driver to pay;

-loading the welding machine on a trailer requires the involvement of two additional people: a crane operator and a sling and requires payment for their labor;

- loading the welding unit onto the trailer requires the involvement of a crane, which leads to the diversion of equipment from performing other work, wasteful fuel consumption, wasteful use of resources, and the creation of dangerous working conditions when performing lifting operations;

- when loading a trailer with a crane, work platforms or transport routes are unnecessarily cluttered for a while, which worsens working conditions and the safety of work;

- when transporting a welded-on welding unit, trucks or tractors with sufficient traction are used, but there will be an excessive consumption of fuel due to incomplete loading of the towing vehicle;

- a vehicle used to tow a hook-on welding unit is distracted from performing other transport operations or is idle during welding;

They are responsible for the irrational use of finance, metals, energy sources, human resources, production space required for the production of a vehicle or lifting gear, and, in general, for environmental pollution.

These disadvantages are partially eliminated if the welding unit is used in combination with a small-sized car or with an electric car. But when installing on a small-sized car, the car engine is irrationally used (only for movement), and when installed on an electric cart, the battery is irrationally used (work in the field).

Of the analogues, the closest in functional use and technical solution that can be adopted as a prototype is a small-sized, highly maneuverable vehicle such as the ET-2054 electric cart with the ADD-3123U1 welding unit installed on it.

Electric car ET-2054 (see passport 2054.00.00.000 PS), which refers to an outdoor vehicle such as an electric car and consists of a driven and driving axles, wheels, frame, cab, cargo area (or body), DC motor, DC power source in the form of a battery, control system, electrical equipment for monitoring the functioning of the corresponding vehicle systems and its components (control system, battery, electric motor), traffic signaling system (left th and right turns, braking, horn) and headlights.

The welding unit ADD-3123U1 (see Passport (DSHIB.561311.001 PS, DSHIB.561311.004 PS, DSHIB.561311.005 PS) is designed for direct current supply of one post during manual arc welding, cutting and surfacing of metals and is an autonomous source of power for the welding arc, in which the welding generator is driven by a diesel engine. The welding unit is equipped with control equipment and instrumentation located on the control panel. All elements of the welding unit are installed and secured to the welded frame and closed capo om for protection against rain and mechanical damage.

The main purpose of the electric cart, as well as other types of electric transport vehicles, is the transportation of goods using electric energy stored in the battery. The use of electric energy stored in a battery for the movement of a vehicle is intended to produce an environmentally friendly vehicle.

with the rest of the mass of the vehicle (800 - 850 kg with a total mass of the vehicle of 1950 kg);

- a large battery charge period (about 8 hours), which leads to large downtime or the need to have an additional battery, which on the other hand leads to a significant increase in the cost of the vehicle (almost 30% or more);

-low efficiency of use of electricity;

-the need to have a special environmentally harmful area for maintenance and recharge of batteries;

- a relatively short period of operation of the vehicle (not more than 7 - 8 hours) on one full battery charge, taking into account technological downtime associated with unloading - loading of goods and special stops in order not to go beyond the required temperature regime of the control system and electric motor. Technological downtime is at least 50% of the vehicle’s operating time;

-high cost of transportation of goods;

-Lack of heating the driver's cab;

-lack of sufficient power (power is about 7 - 8 kW), to perform, in addition to transporting goods, also other work (for example, lifting, locksmithing, shantsevy).

The purpose of the technical solution of the proposed utility model is:

-complex use of energy generated by the engine of the welding unit;

-reduction of the chassis weight due to the removal of the battery;

-decrease in vehicle prices (about 30%) due to the elimination of an expensive battery;

-decrease in operating costs of the battery due to the lack of the need to have a special environmentally harmful area for maintenance and recharge of batteries;

-decrease in costs by eliminating the costs of non-production costs of electricity;

-reduction of technological downtime associated with the features of the battery;

-decrease in the cost of transportation of the welding unit;

-the ability to provide heating for the driver's cab;

-the ability to perform additional work (for example, lifting, locksmith, shantsevy).
