The through shaft 7 is slidably inserted into the barrel cover 5, and the barrel cover 5 is used to limit and hold the through shaft 7, thereby ensuring the stability and flexibility of the through shaft telescopic. The cylinder body of the telescopic cylinder 4 is fixed side by side outside the barrel cover 5, one end of the connecting rod 3 is fixedly connected to the corresponding end of the through shaft 7, and the other end of the connecting rod 3 slides through the bottom of the barrel cover 5, and is correspondingly connected to the telescopic rod end of the telescopic cylinder 4 through the connecting plate 2. While realizing the through shaft telescopic function, the structural layout is more sophisticated, avoiding stress damage that may be caused by the direct connection of the telescopic cylinder 4 to the through shaft 7; in addition, the telescopic cylinder 4 is provided with two and symmetrically arranged on both sides of the barrel cover 5, the middle part of the connecting plate 2 is correspondingly connected to the corresponding end of the connecting rod 3, and the two ends of the connecting plate 2 are respectively connected to the telescopic rod ends of the two telescopic cylinders 4, and the two symmetrically arranged telescopic cylinders 4 can improve the balance and stability of the telescopic control, and also have a certain backup fault tolerance effect.

[0026] The triangular lifting row with pneumatic shaft threading device of the utility model can first lower the hook between the two frame plates 1, and then control the shaft 7 to extend through the telescopic control device, pass through the through holes 101 of the two frame plates 1, and just rest on the hook, and then the wire rope can be wound on the pulley 11 for lifting; after the lifting introduction, it only needs to control the shaft 7 to retract and detach from the hook through the telescopic control device.
