The invention relates to the technical field of hoists, in particular to a mine hoist traction device with a safety auxiliary function, which comprises a rack, a motor, a speed reducer, a winding drum, a steel wire rope, a brake assembly and the like, the upper side of the left part of the rack is connected with the motor, the upper side of the middle part of the rack is connected with the speed reducer, and an output shaft of the motor is connected with the speed reducer; the upper side of the right portion of the rack is connected with a winding drum when rotating, an output shaft of the speed reducer is connected with the winding drum, a steel wire rope is wound around the winding drum, and the front side of the middle of the rack is connected with a brake assembly. When the traction speed is too high, the rotating speed of the winding drum is increased, at the moment, the rotating arm swings due to centrifugal force, the torsional spring deforms, the rotating arm swings to make contact with the speed limiting ring, at the moment, the rotating arm and the rotating frame are decelerated due to friction force, and then the winding drum is decelerated; therefore, automatic deceleration protection is realized during overspeed, and accidents caused by faults of an electric control system can be effectively avoided.
本发明涉及提升机技术领域,尤其涉及一种具有安全辅助功能的矿井提升机牵引装置,包括有机架、电机、减速机、卷筒、钢丝绳和刹车组件等,机架的左部上侧连接有电机,机架的中部上侧连接有减速机,电机的输出轴与减速机相连接,机架的右部上侧转动时连接有卷筒,减速机的输出轴与卷筒相连接,卷筒上绕接有钢丝绳,机架的中部前侧连接有刹车组件。本发明在牵引速度过快时,卷筒的旋转速度便会加快,此时旋转臂便会因离心力进行摆动,扭簧发生形变,旋转臂摆动便会与带动限速环接触,此时便会因摩檫力使得旋转臂和旋转架进行减速,进而实现对卷筒进行减速,从而实现在超速时实现自动减速保护,从而能够有效避免在电控系统出现故障时事故发生。
