The invention discloses a mining movable multi-angle pneumatic lifting device, and belongs to an auxiliary device of mining mounting equipment. The device consists of pipeline placement racks, a supporting frame, supporting legs, a hydraulic pump station, a platform trolley and hydraulic cylinders, wherein the pipeline placement racks are connected with the supporting legs through the supporting frame; the other ends of the supporting legs are connected with the platform trolley; power of the device comes from a pneumatic motor; the hydraulic pump station is driven by the pneumatic motor to control the two supporting legs to produce different heights through an adjusting valve block, so that the pipeline placement racks have different angles to adapt to different mounting sites. The device has the advantages that pneumatic power is converted into mechanical energy by the lifting device through the pneumatic motor, then the mechanical energy is converted into oil-operated pressure energy through the hydraulic pump, the flow entering the hydraulic cylinders of the two supporting legs is changed through adjustment of the valve block, and the two supporting legs can produce different heights and can realize mounting of equipment at underground different heights and different angles. The lifting device is arranged on the mining platform trolley; the purpose of movement is realized by using drive of a winch.
