Description

Technical Field

[0001] The utility model relates to the technical field of breakdown trucks, in particular to an on-vehicle compressed air system that can provide high-pressure gas on a breakdown truck. Background Art

[0002] When a breakdown truck is operating, it usually encounters simple auto repair operations, such as removing tires, inflating tires, and releasing the parking brake of an accident vehicle.

[0003] There are two existing solutions. One is to use the compressed gas of the air braking system on the breakdown truck itself as the power source for pneumatic tools, but there are problems of insufficient air pressure and air volume; the other is to install a conventional electric air compressor on the breakdown truck. This kind of electric air compressor usually uses 220 - 380V alternating current as the power source, so an alternator also needs to be installed on the breakdown truck as the power source for the air compressor. This method has problems such as high cost, large required installation space, and the need for a medium-high voltage electrician operation certificate, etc. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide an air compressor system with a relatively simple structure for a breakdown truck.

[0005] The technical solution adopted to solve the above technical problem: An on-vehicle air compressor system for a breakdown truck, characterized in that it includes an on-vehicle hydraulic power source, a hydraulic motor driven by the hydraulic power source to operate, an air compressor driven by the hydraulic motor to compress air, and an air storage tank for storing the high-pressure air generated by the air compressor.

[0006] On this basis, the hydraulic power source includes a hydraulic control valve for controlling the operation of the hydraulic motor.

[0007] On this basis, a pressure sensor is installed on the air storage tank.

[0008] The beneficial effects brought by adopting the utility model: The on-vehicle air compressor system of the breakdown truck of the utility model utilizes the original hydraulic power source on the breakdown truck to drive the hydraulic motor to operate. Through the transmission mechanism, the air compressor is driven to compress air, and the formed high-pressure air is stored in the air storage tank for the operation of auto repair pneumatic tools (equipment). The on-vehicle air compressor system of the breakdown truck of the utility model has a simple structure, low cost, convenient operation, and can provide the air pressure value and sufficient air volume required for pneumatic work. Brief Description of the Drawings

[0009] Figure 1 The structural schematic diagram of the on-vehicle air compressor system of the breakdown truck of the utility model. Detailed Embodiment

[0010] Such as Figure 1As shown in the figure, a vehicle-mounted air compressor system for a wrecker includes a vehicle-mounted hydraulic power source 1, a hydraulic motor 2 driven by the hydraulic power source 1 to operate, an air compressor 3 driven by the hydraulic motor 2 to compress air, and an air storage tank 4 for storing the high-pressure air generated by the air compressor 3.

[0011] The hydraulic power source 1 is the hydraulic power source provided by the original hydraulic system on the wrecker, and the hydraulic motor 2 is connected to the hydraulic return circuit of the hydraulic system. The transmission connection between the hydraulic motor 2 and the air compressor 3 can adopt a conventional belt drive 5.

[0012] Generally, a hydraulic control valve is usually used to control the start and stop of the hydraulic motor. Therefore, the hydraulic power source 1 should also include a hydraulic control valve 6 for controlling the operation of the hydraulic motor 2. In addition, the control of the switching action of the hydraulic control valve 6 can adopt signal sensor control. Therefore, a pressure sensor 7 can be installed on the air storage tank. The pressure sensor 7 senses the pressure in the air storage tank 4. When the pressure sensed by the pressure sensor 7 reaches the set value, a signal is sent to control the hydraulic control valve 6 to execute the action of closing the hydraulic circuit, and the hydraulic motor 2 stops operating. To improve safety, the pressure sensor 7 can also control a pressure relief valve 8 installed on the air storage tank 4. When the pressure sensor 7 senses that the pressure in the air storage tank 4 exceeds the dangerous value, a signal is sent to control the pressure relief valve 8 to execute the pressure relief action until the pressure in the tank drops back to the safe value, and the pressure relief valve 8 stops relieving pressure.
