Anti-derailing device of bridge-crane trolley walking mechanism

Abstract

The invention discloses an anti-derailment device for a trolley traveling mechanism of an overhead crane, comprising an I-shaped slide rail, a track groove is symmetrically arranged on the side of the I-shaped slide rail, and a trolley sliding block is arranged on the I-shaped slide rail. A bracket is fixedly installed on the trolley sliding block, the bracket has a concave structure, the upper end of the bracket is fixed on the upper surface of the trolley sliding block, the front end of the bracket is provided with a buffer plate, and the buffer plate is provided with a buffer plate At the meeting, limiters are fixedly installed on both sides of the bracket, the limiters are L-shaped, and the limiters are composed of a limiter arm in the vertical direction and a limiter rod in the horizontal direction. One end of the position rod is provided with a groove, the groove is provided with a rotating shaft, a sliding wheel is fixedly installed on the rotating shaft through a bearing, and the sliding wheel is arranged in the track groove, the invention effectively prevents the running machine on the crane. The rail derailment can avoid the occurrence of accidents, and has the advantages of simple structure and easy installation and disassembly.

Description

technical field [0001] The invention relates to the technical field of hoisting equipment, in particular to an anti-derailment device for a trolley traveling mechanism of a bridge crane. Background technique [0002] At present, during the operation of the bridge crane, because the wheel rim on the operating mechanism of the crane is very shallow, if the running motor on one side suddenly gets stuck and fails during driving, the motor on the other side is still running. If the running mechanism is not synchronized, there will be a large torsion force. This torsion force will act on the end beam, causing the end beam to twist. It will cause vicious events such as derailment and falling of the crane, which will not only endanger the personal safety of the operator, but also cause damage to the transported items and cause unnecessary economic losses. In view of this problem, it is necessary to design a bridge type The anti-derailment device of the traveling mechanism of the cr...

[0002] At present, during the operation of the bridge crane, because the wheel rim on the operating mechanism of the crane is very shallow, if the running motor on one side suddenly gets stuck and fails during driving, the motor on the other side is still running. If the running mechanism is not synchronized, there will be a large torsion force. This torsion force will act on the end beam, causing the end beam to twist. It will cause vicious events such as derailment and falling of the crane, which will not only endanger the personal safety of the operator, but also cause damage to the transported items and cause unnecessary economic losses. In view of this problem, it is necessary to design a bridge type The anti-derailment device of the traveling mechanism of the crane trolley to effectively avoid the occurrence of derailment of the crane
