Crane with quick brake positioning function

Abstract

The invention discloses a crane with a quick brake positioning function, and relates to the technical field of cranes. The crane with the quick brake positioning function comprises a supporting column and a connecting beam, the two ends of the connecting beam are fixed to the top of the supporting column, a movable channel is formed between the front side and the rear side of the connecting beam in a penetrating mode, and a transverse driving device is slidably installed in the movable channel. According to the crane with the rapid brake positioning function, the friction speed reduction device is arranged and can drive the friction speed reduction block to move towards the driving disc when the friction speed reduction device is powered on, and the brake pad on the driving disc can rub with the friction speed reduction block at the moment and generates brake operation, so that the transverse driving device and the hoisting device are decelerated and braked; due to the fact that the driving discs rotate at the top of the connecting beam, the guide blocks can guide airflow on one side of the guide blocks in the process of rotating along with the driving discs, the airflow moves towards the two driving discs, and then the heat dissipation effect of the driving discs can be promoted.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a crane with the function of fast braking and positioning. Background technique [0002] A crane refers to a multi-action hoisting machine that lifts vertically and carries heavy objects horizontally within a certain range. Also known as crane, aerial crane, crane. The bridge crane is a lifting device that is horizontally placed over the workshop, warehouse and stockyard for material lifting. Because its two ends are located on tall concrete pillars or metal supports, it is shaped like a bridge. The bridge frame of the bridge crane runs longitudinally along the tracks laid on the elevated sides on both sides, which can make full use of the space under the bridge frame to lift materials without being hindered by ground equipment. It is a kind of hoisting machinery with the widest range and the largest number. [0003] During the lifting and handling process, the crane may need ...

AI Technical Summary

Problems solved by technology

[0003] During the lifting and handling process, the crane may need to perform emergency stop and brake operations. Existing cranes generally perform brake operations through frictional energy consumption of brake pads, but some cranes may require multiple emergency stop and brake operations during a single use. , which will lead to a gradual increase in the temperature of the brake pads in the moving state, thereby affecting the emergency stop braking effect
