Description

IPC VboR 1/48

VEHICLE Technical field to which the utility model belongs

The inventive utility model relates to vehicles equipped with a device for loading and unloading goods, as well as devices for servicing and repairing equipment in the field.

A vehicle is known that contains a chassis, a cargo area is attached to its frame, and a crane manipulator is installed between the driver’s cab and the cargo area for loading and unloading cargoes (see “Unit for transportation of APE-6 electric motors in the reference book“ Complex of units for mechanization of work in the energy economy , Kazan, 1996, 28 pp.)

However, the known vehicle does not have the ability to transport bulky goods, for example, complete transformer substations KTPPN, having a mass of about 3000 kg and a height in the transport position of 2250 mm, since in this case the boom in the transport position will be located at a significantly higher permissible height (4000 mm) . When laying the boom forward over the driver’s cab, the front axle will be significantly overloaded, which will lead to its quick breakdown, deterioration of the vehicle's handling.

This disadvantage is eliminated in another known vehicle containing a chassis, to the frame of which a cargo area is attached to accommodate the transported goods, and a loader crane is installed between the chassis of the driver’s chassis and the cargo area, in which the boom is in the transport position across the chassis. This allows you to transport bulky goods (see Fig. 4, sheet 7, technical specifications TU 4835-001-00239184-95 to the onboard type manipulator MKS-5531 and its modifications, Krast, Stavropol, 355015, 7 Mikhailovsky highway, 7) .

Oh & looking. A disadvantage of the known vehicles is their low profitability due to the impossibility of carrying out maintenance and repair of equipment in the field without the involvement of additional equipment, including welding units, oil filling 1kov.

State of the art

Utility Model Essence

To increase efficiency by providing the possibility of servicing and repairing equipment in the field without involving additional equipment, a known vehicle containing a chassis, to the frame of which a cargo platform is attached, and a crane mounted between the driver’s cab and the cargo platform, according to a utility model, is equipped with oil delivery system, welding generator with a rated voltage of 36 V, driven by the chassis engine and installed under the cargo area, pneumatically with a solid oil blower and a spray gun connected by pipelines through a pressure reducing valve to the receiver of the consumer of the brake system of the chassis.

Also new is the fact that the oil separator system includes a tank for fresh oil and a tank for waste oil, each of which is designed for a working pressure of not more than 0.07 MPa (0.7 kg / cm), connected by pipelines to the receiver of consumers of the brake system of the chassis through pressure reducing valve, equipped with a safety valve and a vacuum circuit breaker, connected in series by pipelines with a flame arrester and an ejector mounted on the exhaust system of the chassis.

Under these conditions, the “Rules for the design and safe operation of vessels operating under pressure PB10-115-96 do not apply to the oil release system.

Information confirming the feasibility of implementing a utility model

The vehicle contains the chassis 1 of an all-terrain vehicle, for example, KamAZ-43106 or KamAZ-43118, to the frame of which a cargo platform 2 is attached. A crane 3 is installed between the driver’s cab and the cargo platform, for example, type MKS-5531A2 of the Stavropol Automobile Plant cranes (Krast JSC) for loading and unloading goods. A welding generator 4 with a rated voltage of 36 V (for example, GD-4002U2 or GD-4004U2) is installed under the cargo area 2.

hoses 7 and 8. Tanks 5 and 6 are equipped with safety valves and vacuum circuit breakers, connected by pipelines 9, 10d11 and 12 to the receiver 13 of the consumers of the brake system of the chassis 1, and by pipelines 14,15,16 - with an ejector 17 mounted on the exhaust system of the chassis 1 and the connected pipe 18 with a flame arrester 19. All pipelines are equipped with shutoff valves. The exhaust system of the chassis has a switch 20. On the tanks 5 and b, viewing windows are installed.

Capacity 21 with fresh oil is installed on the basis of fuels and lubricants (fuels and lubricants) and is designed to fill capacity 5 from it.

Capacity 22 is designed to empty and fill with fresh oil.

The tank 23 is designed to drain the spent liquid from the tank 22.

The pipe 24 is designed to drain fluid from the safety valves.

Pneumatic solid-state blower 25 is connected to the receiver 13 of the consumers of the brake system of the chassis by a pipe 26 with shutoff valves.

The pneumatic spray gun 27 is connected to the receiver 13 by a pipe 28 through a pressure reducing valve 29 and shutoff valves, and containers 5 and b through a pressure reducing valve 30.

To control the pressure in the pneumatic system, a pressure gauge is installed, and a vacuum manometer is installed for the vacuum.

The vehicle is equipped with accessories and tools, providing um carrying out loading, unloading, assembly and dismantling and welding works.

The operation of the crane 3 is drained from the remote control located on its frame.

The welding generator is controlled by the remote control installed in the cargo area 2.

The vehicle operates as follows

Before leaving for repair work, loading is carried out, setting the vehicle in the most convenient position relative to the cargo intended for loading and turning on the pump for supplying the working fluid to the hydraulic system of the crane 3, load the cargo.

After loading, the crane 3 is transferred to the transport position.

position relative to the intended place of unloading of goods and, turning on the pump for supplying the working fluid to the hydraulic system of the crane 3, unload the cargo.

After that, the crane 3 is transferred to the transport position.

For welding work in the cab of the chassis include the drive of the welding generator 4.

The waste oil is taken from the tank 22 to the tank 6 through the intake hose 8, due to the vacuum created in the tank b by the ejector 17 when the switch 20 is switched from the exhaust position to the junction position.

After the end of the intake of waste oil, the ejector 17 is turned off.

Refueling the tank 22 with fresh oil from the tank 5 is carried out through a dispensing hose 7 under the action of compressed air entering through pipelines 9,10,11 and a pressure reducing valve 30 with shutoff valves from the consumer receiver 13.

After refueling of the tank 22 with fresh oil, the supply of compressed air is stopped and all controls of the oil delivery system are reset.

The economic effect is achieved due to multifunctional technical capabilities that provide a range of works on repair and maintenance of equipment in the field without involving additional equipment for this purpose, and also by reducing the number of staff.

In addition, safety conditions are improved through the use of a pneumatic drive in the oil system and the use of pneumatic solid-state blower and spray gun.
