Hoisting mechanism of crane

一种起重机起升机构

Abstract

本实用新型提供了一种起重机起升机构,包括:卷筒组、减速机、电动机和力矩限制器。所述卷筒组通过卷起或释放钢丝绳以带动吊钩的升起或降落;所述减速机通过卷筒联轴器与所述卷筒组连接;所述电动机用于为所述起重机起升机构提供启动力矩;所述力矩限制器分别与所述电动机和所述减速机连接,用于监测所述减速机的输入轴端的力矩值;当所述力矩限制器监测的力矩值大于预定力矩值时,所述力矩限制器断开与所述电动机和所述减速机的连接,能够及时停止吊钩的升降动作,有效及时的防止事故发生。
The utility model provides a hoisting mechanism of crane, include: reel group, speed reducer, motor and torque limiter. Reel group is through curling up or releasing rise or the descending of wire rope in order to drive the lifting hook, the speed reducer pass through the reel shaft coupling with the reel group link, the motor is used for doing hoisting mechanism of crane provides start -up force moment, torque limiter respectively with the motor with the speed reducer is connected, is used for the monitoring the torque value of the input axle head of speed reducer, when the torque value of torque limiter monitoring is greater than when booking torque value, torque limiter disconnection with the motor with the connection of speed reducer can in time stop the lift action of lifting hook, and effective timely avoid accident takes place.
