Monorail crane emergency braking device

Abstract

The invention discloses a monorail crane emergency braking device. The device which comprises a frame body; a plurality of rotating wheels are symmetrically and movably connected to the two sides of the top end of the frame body; the frame body is clamped on a monorail crane through the rotating wheels and can move; one rotating wheel is a tachometer wheel, and the other rotating wheels are walking wheels; a brake arm assembly is movably connected to the middle of the outer side face of the frame body through a first pin shaft, and a brake block is movably connected to the top end of the outerside face of the brake arm assembly through a second pin shaft; a hydraulic reciprocating assembly is arranged at the bottom end of the interior of the frame body, and a sliding block is fixedly connected to one end of the hydraulic reciprocating assembly; and a manual brake assembly is arranged outside the brake arm assembly, and a speed limiting brake triggering mechanism is arranged on the side face, where the tachometer wheel is located, of the frame body. According to the monorail crane emergency braking device provided by the invention, two different simple and convenient braking modesof the manual brake assembly and the speed limiting brake triggering mechanism are arranged, so that the accident probability after a single braking fault is reduced, and rapid emergency braking can be realized during overspeed.

Description

technical field [0001] The invention relates to the technical field of railcar braking, in particular to an emergency braking device for a monorail crane. Background technique [0002] The monorail crane is a system that uses a special I-beam hanging above the roadway as the track, and is connected by hanging vehicles with various functions to form a train group, which is pulled by traction equipment and runs along the track. Due to the various superior performances of the monorail crane, it has been used more and more widely. For example: the monorail crane can complete the auxiliary transportation from the mining area yard to the working face without reloading, and can be used for the auxiliary transportation operation connecting the main transportation roadway and the mining area roadway. [0003] When the car group travels on the track and needs to stop, it is often braked by a braking device. However, there are the following problems in the prior art: 1. The braking m...
