The invention discloses a lifting telescopic beam. The lifting telescopic beam comprises a main beam body. The two ends of the main beam body are slidably connected with telescopic beam bodies correspondingly, and lifting electromagnets are suspended on the main beam body and the telescopic beam bodies. A driving wheel is arranged on the main beam body. A reel is arranged on the driving wheel. Wire ropes are wound on the reel. One end of one wire rope is drawn from the upper portion of the reel and is connected with the main beam body after passing through a retracting pulley, and the other end of the wire rope is drawn from the lower portion of the reel and is connected with the main beam body after passing through a pulley block. One end of another wire rope is drawn from the upper portion of the reel and is connected with the main beam body after passing through another pulley block, and the other end of the wire rope is drawn from the lower portion of the reel and is connected with the main beam body after passing through another retracting pulley. Each pulley block comprises redirection pulleys and a stretching pulley, and the redirection pulleys are connected to the main beam body. Each telescopic beam body is connected with the corresponding retracting pulleys and the corresponding stretching pulley. The lifting telescopic beam has the beneficial effects that the manufacturing cost and maintaining cost are reduced, materials in different lengths can be lifted conveniently, and the working quality and working efficiency are improved.
Description
technical field [0001] The invention relates to the technical field of jacks, in particular to a telescopic beam for lifting. Background technique [0002] At present, there are several telescopic driving methods for the traditional telescopic lifting beam used for hoisting steel plates: [0003] Driven by a hydraulic cylinder, the device needs to be equipped with a hydraulic station, a hydraulic cylinder, and a tubing reel device, which is bulky, has high processing precision, and is expensive. [0004] Rack and pinion drive mode, the structure of the device is simple, but the failure rate is high, the machining accuracy is high, and the telescopic stroke is limited. The long-stroke gear and halogen rod are easy to bend under force, and are prone to damage due to overload, and two sets of rack and pinion are required. Poor synchronization. [0005] Aiming at the problems in the related technologies, no effective solution has been proposed yet. Contents of the invention ...
