Auxiliary braking system for crane

Abstract

The invention discloses an auxiliary braking system for a crane, and relates to the field of crane equipment. The auxiliary braking system comprises a crane guide rail, a main crane and auxiliary cranes, wherein the main crane is connected to the crane guide rail in a walking mode, lifting equipment is arranged below the main crane, and the two sides of the main crane are connected with the auxiliary cranes through connecting rod sets. The auxiliary braking system has the beneficial effects that when preparation before lifting is carried out, telescopic rods of electromagnetic hydraulic cylinders are controlled to extend, under the linkage of the connecting rod sets, the two auxiliary cranes are controlled to extend towards the two outer sides of the main crane, moreover, the main crane and the auxiliary cranes are linked by sliding rods, so that stress points are dispersed, stress concentration on the crane guide rail is reduced, and the service life of the crane guide rail is prolonged; and the telescopic rods of push-pull type electromagnets are controlled to extend until a top disc abuts against the bottom of the crane guide rail, static braking is carried out on the auxiliarycranes, so that the main crane is prevented from deviating when goods are lifted.

Description

Technical field[0001]The present invention relates to the field of lifting equipment, and more particularly to a auxiliary brake system for a hanging vehicle.Background technique[0002]Lift is a common light lifting device for lifting weights. It works along a crane to move along a track that hangs in the air and transports the goods. Among the process of lifting the cargo, the crane is required to prevent the crane to prevent offset from the lifting position. The traditional lifting truck is convenient to walk, which is small, resulting in a concentrated pressure of the track in the lifting process, which is easier to be bent in the long-term operation process, which affects the walking of the crane; When the lifter is working in a lifting, especially when running with more heavy goods, it is easy to stop, and there is poor stop performance.Inventive content[0003]It is an object of the present invention to provide a auxiliary braking system for a row crane to solve the problems pres...

AI Technical Summary

Problems solved by technology

For the convenience of walking, the traditional crane is set up with a small volume, which leads to the concentrated pressure of the crane on the track during the lifting process, and it is easy to deform and bend the guide rail during the long-term operation process, thereby affecting the walking of the crane; When the crane is performing lifting work, especially when it is operating on heavy cargo, it is easy to have loose brakes and poor brake performance.
