A crane trolley anti-gnawing rail system

Abstract

The invention relates to a rail-gnawing prevention system for a traveling crab. The rail-gnawing prevention system for the traveling crab comprises a traveling crab body, an end plate A and an end plate B are arranged at the left end and the right end of the traveling crab body correspondingly, a laser transmitter A is arranged on the lower surface of the end plate A, and a laser transmitter B is arranged on the lower surface of the end plate B. Mounting plates are arranged at the two ends of the lower surfaces of the end plate A and the end plate B, and an adjusting seat is arranged in the center of the outer side face of each mounting plate. A threaded hole penetrating through the corresponding mounting plate is formed in the center of each adjusting seat, a pin shaft hole penetrating through the axis is formed in the side face of each adjusting seat, and a pin shaft is arranged in each pin shaft hole. An adjusting rod is arranged in each adjusting seat, a strip-shaped through hole is formed in the adjusting rod in the axial direction, and a pressure sensing device is connected to one end of each adjusting rod and connected with a gnawing prevention wheel support. A gnawing prevention wheel is arranged at one end of each gnawing prevention wheel support, each pressure sensing device is connected with a controller, and each controller is connected with an alarm and a storage unit. Generally, the rail-gnawing prevention system for the traveling crab has the advantages of being simple in structure, good in rail-gnawing prevention effect and capable of recording and analyzing traveling crab operation data.

Description

technical field [0001] The invention belongs to the technical field of hoisting machinery, and in particular relates to an anti-gnawing rail system for a crane trolley. Background technique [0002] At present, bridge and gantry crane products belong to special equipment, and are widely used in various fields of national production. The stock base is very large in the country and even in the world. It is very important to operate safely during work. Smash the ground equipment, hurt people's lives, when the crane trolley is hoisting, it is deformed by the hoisting load itself, and the trolley gnaws on the rail caused by other reasons. The anti-derailment device currently used in the project is usually Correction is done mechanically, but it is not possible to monitor the force of the trolley and the deviation in real time, which is inconvenient for subsequent analysis and correction. At the same time, long-term mechanical correction of deviation may cause changes in the stren...

[0002] At present, bridge and gantry crane products belong to special equipment, and are widely used in various fields of national production. The stock base is very large in the country and even in the world. It is very important to operate safely during work. Smash the ground equipment, hurt people's lives, when the crane trolley is hoisting, it is deformed by the hoisting load itself, and the trolley gnaws on the rail caused by other reasons. The anti-derailment device currently used in the project is usually Correction is done mechanically, but it is not possible to monitor the force of the trolley and the deviation in real time, which is inconvenient for subsequent analysis and correction. At the same time, long-term mechanical correction of deviation may cause changes in the strength and shape of the crane track , may cause greater danger
