The invention belongs to the technical field of safety devices, and particularly relates to a safety device used in a lifting platform. The safety device comprises a transverse beam, a universal jointmechanism, a sliding bar, a lock catch and sliding sleeves, wherein two ends of the transverse beam are symmetrically provided with the two sliding sleeves, the transverse beam is detachably installed on two symmetrically distributed sliding beams through the two sliding sleeves, the middle of the transverse beam is provided with the universal joint mechanism, and the sliding bar is slidably installed on the universal joint mechanism. In the safety device, when the sliding bar is vertical, the universal joint mechanism is in a horizontal state. When a worker falls, the sliding bar can be pulled to move downwards through the lock catch, if the sliding bar is in an obliquely swing state at this time, the sliding bar can swing towards the vertical direction relative to the transverse beam inthe downward sliding process, and the sliding bar drives the universal joint mechanism to swing when swinging. In the safety device, by applying a damping action on the rotation of pin shafts in theuniversal joint mechanism in the use process, the sliding bar slowly swings right in the vertical direction, and it is prevented that the worker collides with a sharp object in a swing space in the swing process and gets injured.

    本发明属于安全器技术领域,尤其涉及一种吊台使用的安全器,它包括横梁、万向节机构、滑杆、锁扣、滑套,横梁的两端对称的安装有两个滑套,横梁通过两个滑套可拆卸安装在两个对称分布的滑梁上;横梁的中间安装有万向节机构,滑杆滑动安装在万向节机构上;本发明中当滑杆竖直时,万向节机构处于水平状态。当工作人员掉落时,会通过锁扣拉动滑杆下移,如果滑杆此时处于斜摆状态时,滑杆的下滑的过程中会相对横梁向竖直方向摆动,滑杆摆动带动万向节机构摆动;本发明中通过在过程中对万向节机构中销轴的旋转施加阻尼作用;使得滑杆缓慢竖直摆正;防止工作人员在摆动过程中与摆动空间内的尖锐物体发生碰撞,伤到工作人员。
