Abstract

The invention discloses a brake for a mining safety braking car of a monorail crane. The monorail crane comprises a frame, a brake shoe, a pin shaft, a hinge lug, a disc spring guide sleeve, a disc spring, a piston rod, a piston, a spacer bush, a piston bush and a retaining cap. The disc spring is arranged in the frame and used for braking so as to increase braking force. Besides, the frame is provided with the piston rod which is designed to be stepped, oil pressure area is enlarged, oil pressure is decreased, and accordingly braking difficulty is lowered, and braking effect is guaranteed. Further, a single shaft is used for fixing a rolling block in the brake, certain swing allowance is permitted for the rolling block, a brake surface is guaranteed to fit with a rail web, impact is lowered, braking stroke is shortened, and the whole brake is guaranteed to be capable of braking timely.

Description

technical field [0001] The invention relates to a mine-used monorail crane safety braking car brake. Background technique [0002] When mining coal or iron ore, engineers and technicians or mining workers generally take the inclined shaft man-car to get down to the mine, or take the man-car of the alley to go to and from the work place in the alley. When there is no problem, the underground personnel can work safely, but when there is an obstacle in the running line of the mining man-vehicle, or the winch is out of control, or the traction wire rope is broken, and the automatic actuating mechanism of the man-vehicle fails and the manual actuating mechanism fails. Safety accidents are caused by the use of manned vehicles and personnel riding on mining vehicles. Therefore, there is a relevant standard in China's coal industry standard MT / T 883-2000: it is stipulated that a braking vehicle should be attached after the last manned vehicle. [0003] Existing mining monorail cran...
