The invention discloses mining machinery, and particularly relates to a lifting device for mine supporting operation. The lifting device comprises a lower base, an upper base, a rotating device, a manual mast lifter and a steel beam fixing device. The lower base is a structural steel frame base formed by welding four structural steels and is internally provided with lead screws, a lower sliding block and a slideway. The upper base is welded on the lower sliding block. The rotating device comprises a bearing pedestal, a bearing bush and a rotating shaft. The manual mast lifter is fixedly connected to a lifter bottom plate, the lifter bottom plate is fixedly connected to the top end of the rotating shaft, and the steel beam fixing device is attached to the manual mast lifter. Front-back andleft-right movement is achieved through the base lead screw, 360-degree rotation is achieved through the rotating device, and the problem that the steel beam supporting position is inaccurate is solved. The manual mast lifter is used for lifting a steel beam, manual lifting is replaced with mechanical lifting, economic benefits are increased, and safe production is guaranteed.

    本发明公开了一种矿山机械,具体涉及一种矿井支护作业用升降装置,包括下底座、上底座、旋转装置、手动式桅柱升降机、钢梁固定装置;所述下底座为型钢框架底座,由四根型钢焊接而成,内部设有丝杠、下滑块、滑道;所述上底座焊接在下滑块上;所述旋转装置包括轴承座、轴瓦、旋转轴;所述手动式桅柱升降机固连在升降机底板上,升降机底板固连在旋转轴顶端,钢梁固定装置附着在桅柱升降机上;本发明通过底座丝杠实现前后左右移动,通过旋转装置实现360°旋转,解决了钢梁支护位置不准确的问题;通过使用桅柱升降机举升钢梁,采用机械举升替代人力举升,增加了经济效益,保证了安全生产。
