AI Technical Summary

Technical Problem

The main body of the gantry crane is easily affected by wind, which causes the walking wheel to slide along the track, affecting stability. The existing anti-slip movement device is complex in operation and is prone to rust.

Method used

A gantry crane limit anti-slip device is designed, including a top beam, transmission cable, lifting equipment, driving mechanism and positioning mechanism. The driving mechanism drives the pressure block to move simultaneously through a dual-axis motor, and the positioning mechanism generates frictional force through contact between the pressure block and the top beam to complete the positioning of the lifting equipment.

Benefits of technology

It realizes simple operation and quick positioning of lifting equipment, increases safety during use, and avoids sliding problems caused by wind.

Abstract

The utility model relates to the technical field of gantry cranes, and discloses a gantry crane limiting anti-sliding device which comprises a top beam, a transmission cable is arranged in the top beam, a lifting device is in transmission connection with the outer side of the transmission cable, a driving mechanism is arranged on the outer side of the lifting device, and positioning mechanisms are arranged on the front side and the rear side of the driving mechanism. The driving mechanism comprises a driving assembly, first transmission assemblies, second transmission assemblies and a supporting assembly, the driving assembly is arranged on the outer side of the lifting equipment, the first transmission assemblies are arranged on the left side and the right side of the top of the driving assembly, and the second transmission assemblies are arranged on the front side and the rear side of the driving assembly. According to the limiting anti-sliding device for the gantry crane, through the arranged driving mechanism, a worker only needs to start the double-shaft motor to rotate forwards and backwards to drive the pressing blocks on the front side and the rear side to synchronously move inwards or outwards, the worker can rapidly complete positioning of hoisting equipment, operation is easy, and the worker can conveniently use the limiting anti-sliding device.
