Abstract
The utility model discloses a monorail crane safety arrestment vehicle for mining. A hydraulic system is pressurized through a manual pump, so that a braking block of a brake is separated from a trail web. When the monorail crane safety arrestment vehicle for the mining is used, the hydraulic system is pressurized through addition of energy accumulators to prevent pressure of hydraulic oil inside the brake from decreasing ceaselessly. The pressure of the hydraulic system is displayed though a pressure gage. A displayed value of the pressure gage is required to be observed before the vehicle is operated. When the displayed value decreases, the hydraulic system is pressurized through the manual pump. In a process that the vehicle climbs a slope, when a pull rod between a drive and a load breaks, the load and the safety arrestment vehicle slide down the slope together. When a speed achieves a set speed of a centrifugal releaser, the centrifugal releaser drives a deflector rod to promote releasing of a machinery change valve, and therefore the hydraulic system is unloaded, the brake starts work, and the purpose of protection of the load is achieved. By means of the hydraulic system which is dependent of a hydraulic system of the vehicle, the hydraulic system and the hydraulic system of the vehicle are not affected mutually when the pull rod breaks. The monorail crane safety arrestment vehicle for the mining is simple in structure and easy to achieve.
