Problems solved by technology
[0003] At present, the suspension configured on explosion-proof vehicles in coal mines is basically a leaf spring suspension. Due to the limitations of its structure, such as large mass, easy failure, and rigidity that cannot change with changes in external loads, the operation of explosion-proof vehicles in coal mines is difficult. Comfort, vehicle weight and height are greatly restricted, resulting in poor humanized design of underground transportation vehicles and many potential safety hazards
[0004] As for the control of the suspension, there is basically no configuration in the existing structure, resulting in slow response of the suspension

The invention belongs to the technical field of mining underground auxiliary transportation equipment, in particular to a control system for a suspension device of a mining anti-explosion vehicle, solving the problem that suspension control is not configured in the prior art basically. The control system comprises a gas tank which is connected with a filter assembly, the filter assembly is connected with a one-way valve, the one-way valve is connected with a gas distribution block I, the gas distribution block is respectively connected with a front gasbag height valve and a gas distribution block II, the front gasbag height valve is connected with the gas distribution block II, the gas distribution block II is respectively connected with a left front gasbag and a right front gasbag, a gas distribution block III is respectively connected with a left rear gasbag height valve and a right rear gasbag height valve, the left rear gasbag height valve is connected with a left rear gasbag and the right rear gasbag height valve is connected with a right rear gasbag. The control system has the beneficial effects of real-time detection, sensitive response and high actuating speed and can be used for ensuring the controllability and stability of a mining anti-explosion vehicle.
Description
technical field [0001] The invention belongs to the technical field of underground auxiliary transportation equipment in coal mines, and in particular relates to a control system for a suspension device of an explosion-proof vehicle in a coal mine. Background technique [0002] Coal mine explosion-proof vehicles usually operate in a narrow working space where the environment is harsh, the road surface is rough, there is a lot of dust and coal slime in the roadway, there is often water, and gas is contained, so the height of the vehicle is reduced, the weight is small, and the operating comfort is improved. It has always been an important technical problem. [0003] At present, the suspension configured on explosion-proof vehicles in coal mines is basically a leaf spring suspension. Due to the limitations of its structure, such as large mass, easy failure, and rigidity that cannot change with changes in external loads, the operation of explosion-proof vehicles in coal mines i...
