The invention relates to the technical field of coal mine safety, and discloses a mining pneumatic car arrester which comprises a base, two supporting bases are fixedly installed on one side of the top end of the base, holes are formed in the middles of the supporting bases, the supporting bases are movably connected with rotating shafts in a sleeved mode through the holes, and buffer springs arefixedly connected to the ends, not provided with the supporting bases, of the rotating shafts. A gap exists between the two supporting bases, the outer side of the rotating shaft in the gap is movablysleeved with an outer wheel, and one face of the outer side of the outer wheel is fixedly connected with a blocking claw. Gas is guided into the fixing pipe through the gas absorber, due to the blocking effect of the permanent magnets and other devices, the gas firstly enters the blocking claw to push the permanent magnet to move towards the edge of the blocking claw, so that repulsive force exists between the permanent magnet and the blocking claw, and zero friction exists between the permanent magnet and the blocking claw; and then the blocking claw is opened through the pneumatic device, and therefore, the pneumatic device and other components are prevented from being damaged in the opening process, and the service life of the pneumatic device is prolonged.

    本发明涉及煤矿安全技术领域,且公开了一种矿用气动阻车器,包括底座,所述底座的顶端一侧固定安装有两个支撑座,所述支撑座的中部开设有孔,且通过孔与转轴活动套接,位于所述转轴不设有支撑座的一端固定连接有缓冲弹簧,所述两个支撑座之间存在间隔,且在间隔内的转轴外侧活动套接有外轮,所述外轮的外侧一面固定连接有阻爪。本发明通过气体吸收器对固定管进行气体导入,由于永磁铁等装置的阻挡作用,气体率先进入阻爪中推动永磁铁向阻爪的边缘移动,使永磁铁与阻爪间存在斥力,二者零摩擦力,再使气动装置打开阻爪,达到使气动装置等部件在打开过程中不受损伤的目的,提高了其使用寿命。
