Under the action of the pull rope displacement sensor 10, the extension length of the pull rope is used to judge and detect whether the lifting beam body 52 is in place, thereby improving the accuracy and safety of operation. When the lifting beam body 52 moves to the limiting frames 16 on both sides of the standard section 20, under the action of the spring 14, the limiting frames 16 compress the oblique block 13 and the limiting rod 11, so that the fixing sleeve 12 drives the connecting column 15 in the positioning The plate 54 slides inside, and when the inclined block 13 runs to the limit hole 17, the spring 14 allows the fixing sleeve 12 to drive the connecting column 15 to reset, and then the limit rod 11 drives the inclined block 13 to insert into the limit hole 17, so that the jacking beam body 52 is in place and seated, and at the same time it is connected and fixed with the standard section 20. When it is necessary to loosen the connection between the standard section 20 and the jacking beam body 52, pull the connecting column 15, so that the fixing sleeve 12 drives the limiting rod 11 and the inclined block 13 to leave the limiting hole 17, thereby ensuring stability during the jacking process, effectively avoiding the mistake of manual operation forgetting to connect the standard section 20 with the jacking beam body 52, and enhancing the safety effect. When the tower crane exceeds the limit, the stop button on the control box 26 is used to cut off the power supply, interrupt the current action, and effectively prevent accidents.
