Abstract

The invention discloses an automatic variant reversing mechanism, and belongs to the technical field of oil cylinder automatic control devices. A hydraulic automatic control device which is stable in work, small in pulse and good in reliability is provided. According to the technical scheme for solving the technical problem, the automatic variant reversing mechanism comprises a first power system, a first manual reversing valve, a second manual reversing valve and a second power system, the first power system and the second power system both provide hydraulic power for work components, the first power system controls the switching direction of the first manual reversing valve, the first manual reversing valve controls the oil input and output directions of the second power system, the second power system controls the switching direction of the second manual reversing valve, and the second manual reversing valve controls the oil input and output directions of the first power system. The two power systems of the automatic variant reversing mechanism can carry out alternate reversing with a fixed work period, continuous pressure output is guaranteed, the reversing pulse of a single power system is reduced, and reliability is greatly improved.

Description

technical field [0001] The invention relates to an automatic heterogeneous reversing mechanism, which belongs to the technical field of oil cylinder automatic control devices. Background technique [0002] China is a large coal-producing country, a country that relies heavily on coal energy, and is also a country with a large number of mining disasters. The main causes of mining disasters are man-made reasons such as illegal mining of coal mines, production errors, equipment aging and malfunctions. [0003] When coal mines are mined underground, due to the possibility of gas leakage during the mining process, the gas mixes with air, oxidizes rapidly at high temperature, and forms a shock wave phenomenon. China's coal mine gas explosions are mainly electric sparks and blasting, and the main place is the mining face , the instantaneous temperature generated by the gas explosion is high, the pressure expands quickly, and the gas near the explosion element impacts outward at a s...
