The invention discloses a safety braking device for a lifting stage. The safety braking device comprises a fixing support, a stage plate, a mounting plate, a motor speed reducer and rope arranging wheels, push rods are slidably assembled at one end of the fixing support, telescopic rods are fixedly connected to one ends of the push rods, pin shafts are fixedly connected to one ends of the telescopic rods, plug pins are arranged on a stage site, and the telescopic rods are sleeved with springs. A control system controls the motor speed reducer to pull the four rope arranging wheels to wind four ropes, pull the four pull rods to slide, drive the four telescopic rods to slide and extrude the springs, after the stage plate ascends or descends to a preset position, the rope arranging wheels release the ropes, the four telescopic rods slide under the action of the elastic force of the springs, and the four pin shafts are clamped and embedded in the plug pins, so that safe positioning of the stage plate is achieved, and before a stage is started, the safety plug pins are automatically pulled out, stage lifting can be started, and the situation that after the stage is stopped, using is safe is ensured, safety is high, and stability is high.

    本发明公开了一种升降舞台安全制动装置,包括固定支架、舞台板、安装板、电机减速机、排绳轮,所述固定支架一端滑动式装配有推杆,所述推杆一端固定连接有伸缩杆,所述伸缩杆一端固定连接有销轴,舞台现场设置有插销,所述伸缩杆上套接有弹簧。本发明通过控制系统控制一个电机减速机拉动四个排绳轮进行收卷四根线绳,拉动四个拉杆滑动,带动四个伸缩杆滑动且挤压弹簧,当舞台板上升或下降至预定位置后,排绳轮进行放松线绳,四个伸缩杆在弹簧的弹性力作用下滑动,使四个销轴卡嵌于插销内,实现了对舞台板的安全定位,舞台起动前,安全插销自动拔出,舞台升降可以起动,确保舞台停止后使用安全,安全性高且稳定性好。
