The invention belongs to the technical field of lifting platform safety equipment, and particularly relates to equipment for a lifting platform. The equipment comprises a cross beam, a universal joint mechanism, a sliding rod, a lock catch and sliding sleeves. In the normal use process, when a worker slowly pulls the sliding rod, the sliding rod can slowly drive a ratchet wheel to rotate through transmission of a rack and a gear; the rotation speed of the ratchet wheel is relatively low, the situation that a pawl is stirred and triggered to swing by a large angle cannot happen, and then arc-shaped blocks are triggered to limit corresponding pin shafts; and therefore when the sliding rod is normally and slowly pulled, swing of the universal joint mechanism does not have a damping effect, the universal joint mechanism can be normally used, and movement of the worker cannot be affected. Multiple sets of ball circulation are arranged in the sliding sleeves. The sliding sleeves are divided into two parts, multiple sets of ball circulation are arranged in each part, each set of ball circulation is the same as the ball circulation of a linear bearing, and therefore the sliding resistance can be reduced through the design.

    本发明属于吊台安全设备技术领域,尤其涉及一种吊台用的设备,它包括横梁、万向节机构、滑杆、锁扣、滑套,本发明中在正常使用过程中,工作人员缓慢拉动滑杆的时候,滑杆会通过齿条和齿轮的传动缓慢驱动棘轮旋转,棘轮旋转的速度相对较慢,不会拨动触发棘爪发生大角度摆动,进而触发弧形块对对应销轴的限位;所以本发明在正常缓慢拉动滑杆的时候,万向节机构的摆动不会具有阻尼作用,可以正常使用,不会影响工作人员的移动。本发明在滑套内具有多组滚珠循环;分成两个部分的滑套,每个部分内均具有多组滚珠循环,每一组滚珠循环与直线轴承的滚珠循环相同,这样设计可减小滑动阻力。
