The invention discloses a pneumatic underground hoisting device for a monorail crane. The pneumatic underground lifting device comprises two walking trolleys. The underground ends of the two walking trolleys are connected with a bearing cross beam through a spherical hinge connecting device. A pneumatic hoist is installed in the middle of the bearing cross beam and electrically connected with a manual control valve block. Two lifting chains are arranged on the surface of the pneumatic hoist. Movable pulley devices are arranged below the two ends of the bearing cross beam, and chain wheels are movably connected into the movable pulley devices. The lifting chains of the pneumatic hoist penetrate through the chain wheels of the movable pulley devices, and the other ends of the lifting chains are fixed to the surface of the bearing cross beam. The pneumatic hoisting beam has the characteristics of small size, low space requirement and the like. A main beam is hoisted by gas power in some special occasions, the operation is labor-saving, the action is stable, safety and reliability are realized, and the large load weight can be borne.

    本发明公开了一种单轨吊用气动井下起吊装置,包括行走小车,所述行走小车有两个,两个所述行走小车的地底端通过球铰连接装置连接有承载横梁,所述承载横梁的中间位置安装有气动葫芦,所述气动葫芦与手控阀块电性连接,所述气动葫芦的表面设有两个起重链条,所述承载横梁两端的下方设有动滑轮装置,所述动滑轮装置的内部活动连接有链轮,所述气动葫芦的起重链条穿过动滑轮装置的链轮且另一端固定在承载横梁的表面。本发明气动起吊梁因其体积较小,对空间要求小等特点,在一些特殊的场合采用气体动力实现主梁的起吊,操作省力,动作平稳,安全可靠,且可以承担较大的负载重量。
