The invention relates to the technical field of lifters, in particular to a lifter fixing device. The device comprises a shell, wherein two rotating shafts are connected between the inner walls of thetwo sides of the shell through bearings, two worms are connected to the outer wall of each of the two rotating shafts through flat keys respectively, four connecting cylinders are connected to the outer wall of the bottom of the shell through bolts, a stud is connected into each connecting cylinder through a bolt, a supporting block is arranged at the bottom of each stud, evenly-distributed anti-skid protrusions are arranged at the bottom of each supporting block, a thrust bearing is arranged in each supporting block, and the bottom end of each stud is inserted into the corresponding thrust bearing. According to the device, connecting blocks are driven to move through rotation of a double-thread screw, so that the connecting blocks drive wheels to be folded and unfolded through connectingrods and lifting rods, the wheels can be folded when a lifter mounted at the top of the shell does not move, the lifter is supported only through the studs, the whole operation is simple, convenientand fast, and the device is suitable for practical application.

    本发明涉及升降机技术领域,具体是一种升降机固定装置,包括壳体,壳体的两侧内壁之间通过轴承连接有两个转轴,两个转轴的外壁均通过平键连接有两个蜗杆,壳体的底部外壁通过螺栓连接有四个连接筒,连接筒内部通过螺栓连接有螺柱,螺柱的底部设置有支撑块,支撑块的底部设置有均匀分布的防滑凸起,支撑块内部设置有推力轴承,螺柱的底端插接于推力轴承内部。本发明利用双纹路螺杆的转动带动连接块进行运动,使得连接块带通过连杆和起落杆带动轮子进行收起和放下,因此实现了壳体顶部安装的升降机在不进行移动时可以把轮子进行收起,只通过螺柱进行支撑,整个操作简单方便又快捷,符合实际应用。
