Anti-falling safety device and lifting equipment of industrial door
The invention provides an anti-falling safety device and lifting equipment of an industrial door. A shaft is further arranged on the side edge of a door plate, and the shaft is rotationally connected with a wheel body of a cam; and the shaft is further provided with a torsion spring, and preset torsion of the torsion spring can drive the wheel body to rotate, so that a protruding part of the cam makes contact with the inner wall of a track and is locked. The cam is matched with hard rubber, when a steel wire rope is broken, the cam is released, a lifting door is braked through friction force between the hard rubber and the rail, the lifting door is prevented from falling, and the anti-falling safety device has the advantages of being simple in structure, low in cost, convenient to maintain and the like.
防坠落安全装置和工业门的提升设备，门板的侧边还设有轴，所述与凸轮的轮体可转动连接；所述轴上还设有扭簧，扭簧的预设扭力可驱动轮体旋转，使凸轮的凸出部与轨道内壁接触、锁紧。本发明采用凸轮配合硬质橡胶，当钢丝绳断裂时，凸轮释放，靠硬质橡胶和轨道的摩擦力实现提升门制动，防止提升门坠落，具有结构简单、成本低、维护方便等特点。
