[0024] In some embodiments, the rear end of the rear guide pulley 96 is movably connected to the connecting frame two 97, and the connecting frame two 97 is rotationally matched with the rear end of the movable pulley two 98, which can reduce the friction when the rope 10 is conveyed and can guide the conveyance of the rope 10 at the same time.

The structure of the movable pulley one 94 matches the structure of the movable pulley two 98, and there are two movable pulleys one 94 and two movable pulleys two 98, which are convenient for guiding the rope 10 passing through the inside of the front guide pulley 92 and the rear guide pulley 96, so that the rope 10 can be conveyed smoothly. The front guide pulley 92 is arranged horizontally, the rear guide pulley 96 is arranged vertically, and the rear guide pulley 96 swings synchronously with the movable arm one 91.

[0025] In summary, the power module 4 and the frame 1 are fixedly connected by bolts to generate driving force. The pressure sensor 2 receives the overall pressure change of the device, so that the pulling force in the XYZ three-degree-of-freedom directions can be read. When the device works, data can be read, and the safety during the lifting of heavy objects is guaranteed. The rope winding wheel 5 and the support frame 3 are connected by bearings, and the rope winding wheel 5 and the power module 4 are connected by a reduction motor for power transmission, so as to realize the tightening and release of the rope 10, and the maximum pulling force of 800N can be transmitted. And the pulling force can be adjusted in real time, and the pulling force is adjusted according to the different weights of heavy objects; During the rotation of the rope winding wheel 5, the driving gear 68 is driven to rotate synchronously, so that the driving gear 68 drives the driven gear 67 to rotate, and the driven gear 67 drives the screw rod 66 to rotate, so that the slide bar 63 drives the moving seat 62 to move, and at the same time, the anti-unhooking hook 1 64 and the anti-unhooking hook 2 65 can hug and hook the rope 10, follow the inside and outside changes of the rope 10, and prevent the rope 10 from escaping from the rope winding wheel 5 due to excessive inside and outside angles, so that the pulling angle can be changed during the pulling process, and the rope is still in the device and pulled at a normal working angle to prevent the rope from falling out of the device; the pressure rod 49 presses the rope 10 into the groove of the rope winding wheel 5, so that the connecting ropes can be arranged in an orderly manner, avoiding the problems of stacking, entanglement, and knotting of the connecting ropes during long-term use. Avoid causing safety hazards; The movable wheel 1 94 and the movable wheel 2 98 prevent the rope 10 from escaping from the rear guide rope wheel 96 and the front guide rope wheel 92, and by moving the movable arm 1 91 and the movable arm 2 95, the movable arm 1 91 is moved on the inner side of the support frame 3 to adjust its support angle. At the same time, the movable arm 2 95 will swing on the movable arm 1 91 to change the support angle of the rear guide rope wheel 96 and the front guide rope wheel 92, and guide the movement direction of the rope. The rope head 99 positions the rope 10 that has passed through, so that the pulling direction can be converted and the rope can be pulled at multiple angles. The adjustment of 90 degrees in the left and right directions and 90 degrees in the up and down directions can be achieved to achieve multi-angle pulling. The synchronous wheel 7 cooperates with the active synchronous wheel on the rope winding wheel 5 through the synchronous belt 12. When the rope winding wheel 5 rotates, the active synchronous wheel rotates synchronously, so that the synchronous belt 12 drives the synchronous wheel 7 to rotate. When the synchronous wheel 7 rotates, the reducer 8 follows and drives the encoder 22 to rotate after deceleration to generate data feedback, so as to realize real-time monitoring of the working status of the rope winding structure and the power structure to avoid abnormal conditions when the device is working.
