Abstract

The invention discloses a mobile heavy-duty pin shaft putting on and taking off device, which is composed of a hydraulic lifting trolley (6), a pin shaft guiding support device (4) and an electro-hydraulic push rod (2). The hydraulic push rods (2) are all fixed on the lifting platform of the hydraulic lifting trolley (6), and a locking device (5) that can be fixedly connected with the operating object equipment is fixed on the front end of the lifting platform of the hydraulic lifting trolley (6). . Compared with the prior art, the present invention can not only replace manpower to complete the work of putting on and taking off pin shafts, reduce the labor burden of workers, and eliminate potential safety hazards; it is also small in size and easy to move; it has strong adaptability to the road surface; the height is adjustable .

Description

technical field [0001] The invention relates to a heavy pin shaft putting on and taking off device, in particular to a mobile heavy pin shaft putting on and taking off device. Background technique [0002] The process of flood discharge and lifting gates of the reservoir is relatively complicated, and one of the processes is to manually disassemble and assemble the heavy-duty steel cylindrical pin shaft of the gate; this operation load is heavy and there are great potential safety hazards. Therefore, it is a technical problem to be solved at present to design a mobile type heavy-duty pin putting on and taking off device that can replace manpower to complete the work of putting on and taking off the pin, reduce the work intensity of workers, and eliminate potential safety hazards. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a mobile heavy-duty pin putting on and taking off device that can replace manpower to c...
