Abstract

An automatic anti-slipping device for slope running of a mine car is characterized in that a tension sensing device is arranged at the junction of a horizontal rail and a slope rail, and a protector in linkage with the tension sensing device is arranged on the slope rail. When a steel wire rope is disconnected with the mine car, the protector is automatically in the car blocking state, and the mine car can be retained by a braking retaining plate when slipping down along the slope rail, so that safety of operators at the bottom of the slope rail is guaranteed. When the mine car is connected with a traction rope, the tension sensing device is capable of sensing tension of the traction rope when the mine car slips down along the slope rail, and the tension sensing device transfers the sensed tension to the protector through a tension transfer part, so that the protector is changed to the car running state, and the mine car is guaranteed to slip down to the bottom of the slope rail smoothly. The automatic anti-slipping device for slope running of the mine car needs no manual operation and is safe and reliable to operate, capable of avoiding 'running away' due to the fact that the mine car slips down along the slope rail to injure people when the mine car is disconnected with the traction rope, and the problem of 'running away' in mine shafts troubling people all the time is solved.

Description

technical field [0001] The invention relates to a mining machine, in particular to an automatic anti-slip device for a mine car running on a slope. Background technique [0002] Inclined shafts are the main traffic lanes for mining and transporting mines. There are many inclined shafts in some mines, and inclined shafts are drilled below the inclined shafts. There is no uniform standard for the slope of the inclined shaft, ranging from more than 30 degrees to more than 40 degrees, and its depth varies from tens of meters to thousands of meters. There is a larger horizontal walkway above each inclined shaft, which is equipped with tracks and electric winches, and mine cars are placed on the tracks, and the mine cars are divided into heavy mine cars and empty mine cars. When the winch pulls the heavy mine car up from the inclined shaft, the worker pulls out the bolt, and the wire rope on the winch is separated from the mine car; for the empty mine car, first group the empty m...
