Inclined drift ground stop and linkage safety stop automatic locking device

Abstract

The invention relates to an inclined drift ground stop and linkage safety stop automatic locking device. The inclined drift ground stop and linkage safety stop automatic locking device comprises a pneumatic ground stop arranged at the top end of an inclined drift, wherein the pneumatic ground stop comprises a ground stop transmission rod for blocking a winch; the ground stop transmission rod is rotatable; the ground stop transmission rod is driven by a ground stop cylinder; a safety stop system is arranged above the inclined drift; the ground stop cylinder is connected with a control end; a first sensor is arranged at the top end of the inclined drift; the first sensor is electrically connected with the control end; a second sensor is arranged on the middle part of the inclined drift; the second sensor is electrically connected with the control end; the control end is electrically connected with the safety stop system. Linkage of the pneumatic ground stop, a linkage safety stop and the winch and automation are realized, a professional banksman is not needed, labor force and materials are saved, and slippage accidents caused by failure of an anti-loosening pin are prevented while wrong entrance of a vehicle is avoided; the inclined drift ground stop and linkage safety stop automatic locking device has the advantages of small equipment investment, easiness and convenience in operation, reliability in actions, simple structures and rapid actions of the pneumatic ground stop and the linkage vehicle stop fence structure, and easiness in operation.

Description

technical field [0001] The invention relates to the mineral excavation industry, in particular to an automatic locking device for an inclined roadway ground stop and a linkage safety stop. Background technique [0002] In the mining industry, pneumatic ground gears are installed in the lifting of inclined lanes with flat yards and the uphill and down hills of small mining areas, and linkage pneumatic safety gears are installed at the slope change points of flat yards, which replace the original reset type to a certain extent. The ground gear and the falling tuo type linkage barrier, but when using the linkage pneumatic safety gear of the winch below 1.2 meters, the linkage with the winch is not realized, and the pneumatic ground gear is not linked with the winch. Anyone can operate the pneumatic ground at will. The ground gear, and the self-resetting strength of the ground gear is low, which may easily cause accidents in the transportation and lifting of inclined lanes; when...

[0002] In the mining industry, pneumatic ground gears are installed in the lifting of inclined lanes with flat yards and the uphill and down hills of small mining areas, and linkage pneumatic safety gears are installed at the slope change points of flat yards, which replace the original reset type to a certain extent. The ground gear and the falling tuo type linkage barrier, but when using the linkage pneumatic safety gear of the winch below 1.2 meters, the linkage with the winch is not realized, and the pneumatic ground gear is not linked with the winch. Anyone can operate the pneumatic ground at will. The ground gear, and the self-resetting strength of the ground gear is low, which may easily cause accidents in the transportation and lifting of inclined lanes; when the hooker operates the ground gear and the pneumatic linkage safety gear, sometimes he forgets to close the ground gear, and the ground gear will lose the function of blocking the car. In particular, the car yard where the inclined lane is connected to the main transportation road is very likely to cause vehicles to enter the yard by mistake. It may happen that the vehicle accidentally enters the inclined lane and hits the linkage insurance gear. The safety production has brought many negative impacts. At the same time, the hook worker has to operate the ground gear, the linkage insurance gear, and observe the running status of the vehicle. The actual position of the vehicle running cannot be observed indoors, and the winch can only be observed outdoors. The running position is easy to cause misoperation, scratches by running vehicles, and serious damage to equipment may cause personal accidents
