The invention discloses a lifting device for a raceway planet wheel without a lifting hole, and belongs to the field of lifting devices. The transmission mechanism comprises two sliding blocks arranged at the two ends of the shell respectively, and the sliding blocks are connected with the shell in a sliding mode; the two clamping mechanisms are fixedly connected with the two sliding blocks respectively, and the bottoms of the clamping mechanisms are matched with blocking shoulders in raceway inner holes of the raceway planet wheels; the driving device is in transmission connection with the transmission mechanism, and the driving device drives the two sliding blocks to move in opposite directions so as to drive the two clamping mechanisms to clamp the roller path planet wheel; the ring is fixed in the middle of the upper end face of the shell; the driving device drives the clamping mechanism through the sliding block to clamp the blocking shoulder in the raceway inner hole of the raceway planet wheel, so that an external traveling crane can hoist the raceway planet wheel without a hoisting hole through the hoisting ring, and the technical problems that an existing hoisting device cannot be matched with the raceway planet wheel without the hoisting hole and cannot safely and stably hoist the raceway planet wheel are solved.
本发明公开了一种用于无起吊孔的滚道行星轮的起吊装置,属于起吊装置领域,包括:壳体;传动机构,包括分别设置在壳体两端的两个滑块,所述滑块与壳体滑动连接;两个卡紧机构,分别与两个滑块固定连接,所述卡紧机构的底部与滚道行星轮的滚道内孔中的挡肩相匹配;驱动装置,所述驱动装置与传动机构传动连接,所述驱动装置驱动两个滑块朝相反的方向运动,从而带动两个卡紧机构卡紧滚道行星轮;吊环,固定在壳体上端面中部;驱动装置通过滑块驱动卡紧机构卡紧滚道行星轮的滚道内孔中的挡肩,使得外部的行车能够通过吊环起吊无起吊孔的滚道行星轮,解决了现有的起吊装置不能够适配无起吊孔的滚道行星轮、不能安全稳定的起吊滚道行星轮的技术问题。
