[0022] The arc-shaped clamping rod 407 is in an arc-shaped strip structure, and the sliding base 404 and the connecting rod 405 are symmetrical about the central axis of the supporting base plate 406 .

[0023] In this embodiment, when braking is required, the output power of the output end of the double slot 402 is used to drive the output end to operate, so that the output power of the screw group 403 on the double slot 402 can drive the sliding base 404 to cooperate with the upper connecting rod 405 to move, so that the supporting base plate 406 and the arc-shaped clamping rod 407 cooperate with each other to clamp and position the steel cable 3 to achieve the braking effect.

[0024] The hook assembly 1 includes a first parallel plate 101, a bolt sleeve 102, a vertical hanger 103, a shock absorber 104, a second parallel plate 105, a hook base 106, a hook body 107 and a threaded rod 108. The top side of the first parallel plate 101 is provided with a bolt sleeve 102 for bolt assembly, and the vertical hanger 103 is provided above the bolt sleeve 102. The shock absorber 104 is provided on the inner side of the vertical hanger 103, and the top side of the vertical hanger 103 is provided with a second parallel plate 105 for bolt assembly.

[0025] In this embodiment, when in use, a bolt sleeve 102 connected by bolts is provided between the first parallel plate 101 and the second parallel plate 105 so that the vertical distribution of the vertical bracket 103 and the shock absorber 104 can increase the stress strength of the device.

[0026] A hook base 106 assembled with bolts is provided on the inner bottom side of the first parallel plate 101 , and a hook body 107 is provided below the hook base 106 . A threaded rod 108 is provided above one end of the hook body 107 .

[0027] In this embodiment, when the product needs to be taken, the hook body 107 below the hook base 106 is used to hook the product, and the threaded rod 108 is threadedly connected to the upper end of the hook body 107 to achieve a locking effect.

[0028] The pulley component 2 includes a connecting plate 201, a wheel plate 202, a side base 203, an expansion frame 204, a first moving wheel 205, a fixed pulley 206, a second moving wheel 207 and an axle base 208.

[0032] The working principle of the safe crane lifting pulley group is as follows: when in use, a bolt sleeve 102 connected by bolts is set between the first parallel plate 101 and the second parallel plate 105, so that the vertical distribution of the vertical hanger 103 and the shock absorber 104 can increase the force strength of the equipment. When it is necessary to take the product, the hook body 107 under the hook base 106 is used to hook the product, and the threaded rod 108 is threadedly connected to the top of one end of the hook body 107 to achieve a locking effect, and then the steel cable 3 is used to slide through the expansion frame 204 on the inner side of the side base 203 to slide. The dynamic sleeve connection achieves an expansion effect, and enables the first moving wheel 205, the fixed pulley 206, and the second moving wheel 207 on the inner side of the axle base 208 to slide and fit together, so that the pulley component 2 can achieve a lifting effect. When braking is required, the output end of the double slot 402 is used to output power to drive the output end to operate, so that the output power of the screw group 403 on the double slot 402 can drive the sliding base 404 to cooperate with the connecting rod 405 to move, so that the supporting base plate 406 and the arc-shaped clamping rod 407 cooperate with each other to clamp and position the steel cable 3 to achieve a braking effect.
