[0025] Specifically, an inner shaft 21 is installed inside the device main unit 2, and one end of the inner shaft 21 is connected to a connecting shaft 23, a rotating ring 24, a brake 25 and a reducer 26. The reducer 26 can slow down the retraction and release speed of the wire rope 3. The brake 25 can stop the rotation of the device main unit 2 when the wire rope 3 descends too fast. The inner shaft 21 is connected to the device main unit 2 through a connector 22, so that the inner shaft 21 and the device main unit 2 rotate synchronously, thereby increasing the safety of the lifting equipment during operation.
[0026] The device shock absorbing mechanism includes: a connector shaft 54 connected to the rear of the device main body 2, a shock absorbing spring 55 is arranged in the middle of the connector shaft 54, and a bottom ring 53 is fixedly installed at the bottom of the connector shaft 54, and a connecting plate 52 is fixedly installed below the bottom ring 53, a support frame 5 is fixedly installed below the device main body 2, and a bottom mounting plate 51 is fixedly installed at the bottom of the support frame 5; hexagonal screw holes are equidistantly arranged on the surface of the bottom mounting plate 51, and the connector shaft 54 connects the device main body 2 and the bottom ring 53.
[0027] Specifically, a support frame 5 is installed below the device mainframe 2, and a bottom mounting plate 51 is installed below the support frame 5. The bottom mounting plate 51 fixes the bottom of the device mainframe 2 through screw holes, and a connector shaft 54 is connected to the rear of the device mainframe 2.

The hook 64 is used to connect the lifting device and the object, so as to facilitate the lifting or lowering of the object. When the object is installed, it is lifted to the device host 2, and the device host 2 lowers the wire rope 3 to a certain length to lift the object. When the object is lifted, the wire rope 3 outside the device host 2 will be continuously reeled. By inlaying a groove 6 on the outside of the device host 2 and installing a partition plate 61 on one side of the groove 6, the wire rope 3 can be spaced apart to prevent the wire rope 3 from The outside of the device main unit 2 is randomly entangled and knotted; when the object is lifted and lowered, a connecting shaft 23, a rotating ring 24, a brake 25 and a reducer 26 are arranged on one side of the inside of the device main unit 2. The reducer 26 can slow down the retraction and release speed of the wire rope 3. The brake 25 can stop the rotation of the device main unit 2 when the wire rope 3 descends too fast, so as to avoid the falling of the object caused by the too fast descending speed of the wire rope 3. When the device main unit 2 is working, a relatively strong vibration will be generated. A connector shaft 54 is connected to the rear of the device main unit 2, and a shock-absorbing spring 55 is arranged in the middle of the connector shaft 54. The shock-absorbing spring 55 weakens the vibration force generated by the operation of the device main unit 2, so that the device main unit 2 runs smoothly, thus completing the entire use process of the wire retracting and releasing device of the entire lifting mechanical equipment.
