[0018] As Figures 1 to 4As shown in the embodiment, the utility model includes drive module 1, self -control speed difference ware 2, counterweight 3, hook 4, drive module 1, self -control speed difference ware 2 all are arranged in the top of counterweight 3, hook 4 is set in the below of counterweight 3, drive module 1 is connected with counterweight 3 through first steel wire rope 5, counterweight 3 is provided with drum assembly, the winding wheel of self -control speed difference ware 2 is provided with second steel wire rope 6, second steel wire rope 6 passes through drum assembly and is connected with hook 4.

[0019] Drive module 1 includes winch, hand-operated cable reel, pulley rope, self -control speed difference ware 2 is used to protect the safety of maintenance personnel, avoids the accidental falling of maintenance personnel in high altitude operation, even if accidental falling can quickly and effectively guarantee personnel safety, can quickly brake locking falling personnel within the limited distance, protects the life safety of personnel. Drive module 1 drives counterweight 3 lifting through first steel wire rope 5. When counterweight 3 presses hook 4 and drops to lower height, the link that user needs to climb first or uses tool to pull down hook is saved, and the weight of counterweight 3 is enough to pull hook 4 and steel wire rope, which can pull hook 4 down when the device is descending, achieving the use purpose. Hook 4 is used for buckling full-body safety belt of user.

[0020] As Figures 1 to 4 As shown in the embodiment, the drum assembly includes eight arc surface drums 7, and the eight arc surface drums 7 are divided into four groups of drum sets. The drum sets are sequentially arranged from top to bottom, and the rolling direction of the upper drum set is perpendicular to the rolling direction of the lower drum set. The central passage formed by the eight arc surface drums 7 is used to stabilize the counterweight 3 by the drive module 1, thereby lifting the hook 4. The user needs to climb first or use a tool to pull down the safety hook, thereby improving the overall use convenience and safety.

[0021] As Figures 1 to 4 As shown in the embodiment, the side of the counterweight 3 is provided with a U-shaped groove 8, the U-shaped groove 8 is provided with a U-shaped mounting block 9, and the arc surface drum 7 is arranged on the inner side of the U-shaped mounting block 9 through a first ball bearing 13. The arc surface drum 7 is equipped with the first ball bearing 13, which reduces the rolling resistance. A space is reserved in the middle of the four groups of drum sets to allow the second steel wire rope 6 to slide freely in the middle, thereby restricting the movement direction of the second steel wire rope 6 without hindering the sliding of the second steel wire rope 6.

[0022] As Figures 1 to 4 As shown in the embodiment, the distance between the arc surface drums 7 is matched with the size of the second steel wire rope 6. The distance between the arc surface drums 7 only allows the steel wire rope to pass through, and does not allow the hook 4 to pass through.

[0023] As Figures 1 to 4 shown in the embodiment, the end of the second steel wire rope 6 is provided with a connecting piece 10, the connecting piece 10 comprises a spring and a rubber block, the hook 4 is connected with the connecting piece 10, and the width of the connecting piece 10 is greater than the interval distance of the curved drum 7. The interval distance of the curved drum 7 only allows the steel wire rope to pass, and does not allow the hook 4 to pass. When the device descends, the counterweight 3 can descend by pressing the hook 4; when the device rises, the hook 4 is still constrained by the curved drum 7 and will not be higher than the lifting device.

[0024] As Figures 1 to 4 shown in the embodiment, the top of the counterweight 3 is provided with a rotating ring 11, the end of the first steel wire rope 5 is connected with the rotating ring 11, the inside of the counterweight 3 is horizontally provided with a second ball bearing 12, and the bottom of the rotating ring 11 is matched with the second ball bearing 12.

[0025] The driving module 1 driven by electricity or manually stabilizes the counterweight 3 through the rotating ring 11, the rotating ring 11 rotates by itself through the second ball bearing 12, the rotating ring 11 can avoid unnecessary rotation of the counterweight 3 due to winding of the first steel wire rope 5, stability of the drum combination is guaranteed, and winding of the steel wire rope is reduced.

[0026] As Figures 1 to 4 shown in the embodiment, the driving module 1 is arranged directly above the rotating ring 11, the self-control speed difference device 2 is arranged directly above the drum group, and the first steel wire rope 5 and the second steel wire rope 6 are arranged in parallel.
