AI Technical Summary

Technical Problem

The existing gantry cranes are prone to blocking the guide rail mechanism due to dust and debris during open-air operations, resulting in failure, poor cleaning effect, high labor intensity and low practicality.

Method used

A guide rail mechanism for large gantry cranes is designed, including cleaning mechanism main body, sliding chute, moving groove, vacuum cleaner mechanism, moving block, pull plate, thrust spring and side, lower brush head and other components. Through the cooperation of these components, automatic cleaning of dust and impurities in the guide rail is achieved.

Benefits of technology

It effectively reduces the blockage of dust and debris in the guide rail mechanism, improves the cleaning effect, reduces the labor intensity of staff, reduces the cleaning burden, and avoids the crane failure due to blockage.

Abstract

The utility model relates to the technical field of large-scale portal cranes, in particular to a guide rail mechanism for a large-scale portal crane, which is characterized in that a chute is formed in a cleaning mechanism main body; a pulling plate is arranged on the moving block; the cleaning device has the beneficial effects that thrust springs are matched with the moving blocks and the moving grooves, so that the moving blocks can move back and forth along the moving grooves, the side brush heads make contact with the inner side face of the guide rail body all the time, uneven planes can be cleaned, and cleaning dead angles are reduced; the upper surface in the guide rail body of the lower brush head is in contact all the time, uneven surfaces can be cleaned, cleaning dead angles are reduced, a dust collection mechanism can remove dust in the guide rail body through a through groove, the device can clean impurities and dust attached to the interior of the guide rail body, and the cleaning effect is good. And dust is prevented from blocking the groove in the guide rail main body to cause crane faults, the guide rail main body does not need to be manually cleaned, and the workload of workers is relieved.
