Monorail crane bidirectional anti-sliding device based on inner ratchet mechanism

Abstract

The invention discloses a monorail crane bidirectional anti-sliding device based on an inner ratchet mechanism. The device comprises a vehicle following stabilizing mechanism, a track, a front clamping mechanism and a rear clamping mechanism, wherein the front clamping mechanism and the rear clamping mechanism are opposite in rotation direction, the vehicle following stabilizing mechanism comprises a protective shell, a middle vehicle capable of sliding and a hydraulic cylinder controlling the middle vehicle to slide are arranged in the protective shell, a front vehicle and a rear vehicle are fixed to the front end and the rear end of the protective shell respectively, each clamping mechanism comprises a corresponding left ratchet device and a corresponding right ratchet device, each ratchet device comprises a corresponding fixing rod, a plurality of inner ratchets capable of rotating unidirectionally are fixed to the two ends of the sides, close to the track, of the fixing rods correspondingly, the inner ratchets on the front clamping mechanism and the rear clamping mechanism are opposite in rotation direction, the two ends of the fixing rods on the front clamping mechanism are hinged to the front vehicle and the middle vehicle by means of front rocker arms correspondingly, and the two ends of the fixing rods on the rear clamping mechanism are hinged to the rear vehicle and the middle vehicle by means of rear rocker arms correspondingly. The device can achieve a monorail crane bidirectional anti-sliding function, prevents a monorail crane from sliding, guarantees the safety of operators and achieves safe transportation.

Description

technical field [0001] The invention relates to the field of transportation equipment, in particular to a two-way anti-rolling device for a monorail crane based on an internal ratchet mechanism. Background technique [0002] Coal mine auxiliary transportation is an extremely important part of coal mine production, and it undertakes the transportation of staff, mining equipment and coal gangue. As an important modern and efficient auxiliary transportation equipment, monorail cranes have incomparable advantages over small winches, rack cars, and trackless rubber-tyred cars, and can be applied to the floor conditions of most coal mines in my country. During the operation of the monorail crane, due to insufficient pressure of the clamping cylinder, excessive wear of the driving wheel, excessive wear of the brake block, high-angle transportation slope, and I-beam 6 track in summer, it is easy to slip after parking. , Skidding problem. At present, there are few domestic studies ...

AI Technical Summary

Problems solved by technology

During the operation of the monorail crane, due to insufficient pressure of the clamping cylinder, excessive wear of the driving wheel, excessive wear of the brake block, high-angle transportation slope, and I-beam 6 track in summer, it is easy to slide after parking. , skid problem

At present, there are few domestic studies on the problem of monorail cranes, and coal mining companies have no reliable devices to solve this problem, and it is difficult to guarantee the safety of coal mine production.
