Lifting mechanism for a crane

Abstract

The invention discloses a hoisting mechanism for a crane, and relates to the technical field of hoisting equipment auxiliary accessories. The hoisting mechanism comprises a body, an anti-sliding mat is arranged on the outer wall of the bottom of the body, extending plates are welded to the outer walls of the bottoms of the two sides of the body and are connected with the inner wall of the bottom of a hoisting groove of the crane through locking bolts, clamping grooves are formed in the outer wall of the upper portion of the body, heat radiating nets are installed on the right sides of the clamping grooves and inside the body, limiting grooves are formed in the outer walls of the upper portions of the heat radiating nets, motors are arranged on the limiting grooves, and heat radiating windows are inlaid into the outer wall of the upper portion of the body and above the motors. The hoisting mechanism is provided with heat radiating windows and the heat radiating nets, the motor can generate a large quantity of hot air during work, the speed of exchange of the hot air with cooling air inside the external environment can be effectively increased, and the normal working efficiency and working time of the motors are guaranteed; and meanwhile, the heat radiating nets can cool the motors and avoids the problem that the working state is abnormal or the motors are damaged by burning dueto too high temperature.

Description

technical field [0001] The invention relates to the technical field of lifting equipment auxiliary accessories, in particular to a lifting mechanism for a crane. Background technique [0002] A crane refers to a multi-action hoisting machine that vertically lifts and horizontally transports heavy objects within a certain range, also known as a crane, an aerial crane, and a hoist; and the most important part of a crane is the lifting mechanism, which is also called the lifting mechanism. The "lifting mechanism" is an essential part of a crane and is the basic structure for lifting and lowering an item. The lifting mechanism drives the reel to rotate through the hoisting motor through the coupling through the hollow shaft of the reducer, so that the wire rope wound on the reel / The cable drives the hook device up or down. [0003] The traditional crane hoisting mechanism has the following disadvantages: the steel rope in the traditional equipment is easy to rub against the h...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a hoisting mechanism for a crane, which solves the problem that the steel rope in the hoisting mechanism of a traditional crane is easy to rub against the hoisting mechanism, thereby increasing its production burden and reducing its service life. The traditional crane lifting mechanism will generate a lot of heat after a long time of work, which will cause the equipment to be overheated and easily cause burns to the staff and abnormal operation of the equipment
