The invention discloses a lifting frame for coal mine out-of-well transportation. The lifting frame comprises a frame body, wherein two symmetrical strip-shaped through holes are formed in the top ofthe frame body; two symmetrical sliding rods are arranged in the frame body, and the two ends of each sliding rod are fixedly connected with the inner bottom wall and the inner top wall of the frame body correspondingly; and two symmetrical sliding rings are arranged on the outer surface of each sliding rod in a sleeving mode, and the inner walls of the sliding rings are connected with the outer surfaces of the sliding rods. According to the lifting frame for coal mine out-of-well transportation, a coal mine can be conveniently loaded into a lifting hopper and unloaded from the lifting hopper,the lifting hopper and the sliding rings can be connected together, the sliding rings slide on the sliding rods, the situation that the lifting hopper is damaged due to the fact that the lifting hopper touches the ground due to too fast descending can be effectively avoided when the lifting hopper descends, the lifting hopper can be driven to ascend and descend, a first gear and a second gear canbe driven through rack transmission power, the lifting hopper can be driven to ascend when pulleys roll in the forward direction, and the lifting hopper can be lifted more stably.
本发明公开了一种煤矿出井运输升降架,包括框架,所述框架的顶部开设有两个相对称的条形通孔,所述框架的内部设有两个相对称的滑杆,且滑杆的两端分别与框架的内底壁和内顶壁固定连接,所述滑杆的外表面套设有两个相对称的滑环,且滑环的内壁与滑杆的外表面相接处。该煤矿出井运输升降架,能够方便煤矿装进升降斗内和方便将升降斗内的煤矿卸下来,能够将升降斗和滑环连接在一起,利用滑环在滑杆上滑动,能够在升降斗下降时有效避免下降过快使升降斗碰触地面发生损坏的情况,能够将带动升降斗上升和下降,能够通过齿条传动动力带动第一齿轮和第二齿轮,能够在滑轮正方向滚动时带动升降斗上升,能够使升降斗升降时更加的平稳。
