[0016] Preferably, an arc-shaped telescopic rod is fixedly connected to the inner wall of the outer wall of the fixed ring, and the arc-shaped telescopic rod is a multi-section arc-shaped rod-shaped structure. The lifting slider and the outer wall of the magnetic plate are inclined surfaces. One end of the arc-shaped telescopic rod is magnetic to the inner wall of the magnetic groove, and the magnetism of the arc-shaped telescopic rod on the side opposite to the magnetic groove is that opposite poles attract each other. The outer wall of the magnetic plate and the inner wall of the sliding groove are magnetic, and the magnetism of the outer wall of the magnetic plate and the inner wall of the sliding groove on the side opposite to each other is that opposite poles attract each other.

[0017] The present invention provides a load detection cable steering unloading pay-off device, which has the following beneficial effects:

[0018] 1. The present invention provides a cable binding mechanism, and the cable is placed in the annular groove in the cable drum, and the cable will be stuck in the annular groove. At this time, with the arc shape of the cable releaser and the overall arc arrangement of multiple cable drums, the cable is stuck in the annular groove in each cable drum one by one, and then the cable is pulled, so that each cable drum will quickly rotate in the cable releaser with a rotating rod, so that the cable can be pulled to move quickly and turn. At the same time, the large arc curvature and multiple rotating cable drums allow the cable to be fully bent naturally, avoiding damage caused by friction and deformation caused by over-bending. When the cable moves, the grooves opened on the outer wall of the cable and the outer wall of the annular groove increase the friction between them, so that the cable can effectively drive the annular groove to rotate, avoiding the cable sliding too fast and slipping on the annular groove, which causes scratches caused by mutual friction.

[0019] 2. The present invention sets a cable restraint mechanism. When the annular groove rotates, the rapidly rotating annular groove and the cable drum come into contact with the cable, and the residue on the outer wall of the cable adheres to the inner wall of the groove. When the cable drum rotates, the groove comes into contact with the elastic bristles in the rear cable release device, and the elastic force of the elastic bristles extends into the groove, and the residue particles in the groove are moved to be fully swept out. The outer wall of the cable and the annular groove and the groove are cleaned in real time, ensuring that the cable drum itself will not adhere to a large amount of residue particles and dust under long-term transmission, thereby avoiding the occurrence of scratching damage to the outer wall of the cable;

[0020] 3. The present invention sets a cable restraint mechanism, and with the rotation of the cable drum, drives the fan blades on the outer wall to rotate synchronously, forming an upward and downward air circulation, and quickly blows out the dust on the outer wall of the cable through the flow of air to keep the cable clean. At the same time, through the rotation of the fan blades, the elastic bristles are constantly contacted and moved, and the dust adhered to the elastic bristles is swept away by the elastic force of the elastic bristles, so that comprehensive self-cleaning is achieved, and the transmission efficiency and transmission quality of the cable are guaranteed;

[0021] 4. The present invention sets a cable binding mechanism, and the upper and lower lifting sliders and magnetic plates are squeezed toward the middle, and the lifting slider slides on the fixed slide bar, which pushes the annular bearing and the lifting scraper to lift vertically, so that the upper and lower annular bearings and the lifting scraper are close to each other and push the cable in the middle, so as to achieve the tight contact and bundling effect of the cable. The faster the cable transmission speed is, the faster the rotation speed of the cable drum is, and the greater the pressure of the annular bearings pushing the cable against each other. Therefore, the cable can be more tightly bound at a faster transmission speed, and the problem of cable tangling can be adaptively prevented.

[0022] 5. The present invention achieves a full cleaning effect on the annular groove and prevents the adhesion of residues by setting a cable protection mechanism. When the lifting slider and the magnetic plate are lifted and squeezed to squeeze the air in the sliding groove, the air is squeezed into the vent through the magnetic plate, and then enters the annular vent groove through the vent, and then enters the fixed ring through the annular vent groove, and pushes the arc-shaped telescopic rod in the fixed ring, so that the arc-shaped telescopic rod is pushed out. Since the fixed ring is fixed by the inner wall of the wire releaser, it cannot rotate. At the same time, the inside of the arc-shaped telescopic rod is pushed by the air to expand and retract. The multi-section arc-shaped telescopic rod is pushed out to fully cover the cable in the annular groove and keep it stationary, so as to prevent the problem of cable derailment and tangled wires. The cable transmission is further protected, and the cable transmission efficiency and stability are effectively improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] Example 1: Please refer to Figure 1-5 , the present invention provides a technical solution: a load detection cable steering unloading release device, comprising a release device 2, a bolt 1 is threadedly connected to the top of the release device 2, and a cable binding mechanism 3 is arranged inside the release device 2;

[0038] The cable restraint mechanism 3 comprises:

[0039] The rotating rod 301 is a circular columnar structure, and the outer wall of the rotating rod 301 is fixedly connected to the wire drum 302. The rotating rod 301 is used to rotate synchronously with the wire drum 302;

[0040] Cavity 303, which is provided in the inner wall of the unwinder 2, the outer wall of the rotating rod 301 is rotatably connected to the inner wall of the cavity 303, the outer wall of the wire drum 302 is provided with an annular groove 304, and the outer wall of the annular groove 304 is provided with a groove 305, and the cavity 303 is used to receive the rotation of the rotating rod 301;

[0041] When in use, the releaser 2 is fixed in a suitable position by bolts 1, the releaser 2 is fixed, and then the cable is put into the annular groove 304 in the cable drum 302, and the cable will be stuck in the annular groove 304. At this time, with the arc shape of the releaser 2 and the overall arc arrangement of multiple cable drums 302, the cable is clamped one by one in the annular groove 304 in each cable drum 302, and then the cable is pulled, so that each cable drum 302 will quickly rotate in the releaser 2 with the rotating rod 301, so that the cable can be The cable can be pulled to move quickly and turn. At the same time, the large arc curvature and multiple rotating cable drums 302 allow the cable to be fully bent naturally, avoiding damage caused by friction and deformation caused by bending too much. When the cable moves, the grooves 305 opened on the outer wall of the cable and the outer wall of the annular groove 304 will increase the friction between them, so that the cable can effectively move the annular groove 304 to rotate, avoiding the cable sliding too fast and slipping on the annular groove 304, which will cause scratches caused by mutual friction.

[0042] Example 2: Please refer to Figure 1-9 Based on the first embodiment, the present invention provides a technical solution: the outer wall of the wire drum 302 is fixedly connected with a fan blade 306, and the inner wall of the groove 305 is rectangular.

[0043] The inner wall of the cavity 303 is fixedly connected with elastic bristles 307, the outer wall of the elastic bristles 307 contacts the outer wall of the blade 306, and the outer wall of the elastic bristles 307 contacts the outer wall of the annular groove 304 and the outer wall of the groove 305;

[0044] At the same time, when the annular groove 304 rotates, the rapidly rotating annular groove 304 and the cable drum 302 come into contact with the cable, and the residue on the outer wall of the cable adheres to the inner wall of the groove 305. When the cable drum 302 rotates, the groove 305 comes into contact with the elastic bristles 307 in the rear cable releaser 2, and is extended into the groove 305 by the elastic force of the elastic bristles 307, and the residue particles in the groove 305 are moved to be fully swept out. The outer wall of the cable and the annular groove 304 and the groove 305 are cleaned in real time, ensuring that the cable drum 302 itself will not adhere to a large amount of residue particles and dust under long-term transmission, thereby avoiding the occurrence of scratching damage to the outer wall of the cable.

[0045] As the cable drum 302 rotates, the fan blades 306 on the outer wall rotate synchronously, forming an upward and downward air circulation, and the dust on the outer wall of the cable is quickly blown out by the air flow to keep the cable clean. At the same time, the fan blades 306 rotate, and continuously contact and move the elastic bristles 307, sweeping the elastic bristles 307, and the dust adhered to the elastic bristles 307 is fully shaken off by its own elastic force, thereby achieving comprehensive self-cleaning and ensuring the transmission efficiency and quality of the cable.

[0046] Example 3: Please refer to Figure 1-13 On the basis of Embodiment 1 and Embodiment 2, the present invention provides a technical solution: a cable protection mechanism 4 is provided on the outer wall of the cable drum 302, and the cable protection mechanism 4 includes a sliding groove 401, and the sliding groove 401 is opened inside the cable drum 302. A lifting slider 402 is slidably connected to the inner wall of the sliding groove 401, and the outer wall of the lifting slider 402 does not contact the inner wall of the sliding groove 401. A magnetic plate 403 is fixedly connected to one end of the lifting slider 402, and the outer wall of the magnetic plate 403 is slidably connected to the inner wall of the sliding groove 401.

[0047] A vent hole 404 is formed on the inner wall of the sliding groove 401 , and a magnetic groove 407 is formed on the outer wall of the wire drum 302 .

[0048] The inner wall of the vent hole 404 is communicated with the interior of the sliding groove 401 , an annular vent groove 405 is provided on the outer wall of the wire drum 302 , and the inner wall of the vent hole 404 is communicated with the inner wall of the annular vent groove 405 .

[0049] The outer wall of the wire drum 302 located at the bottom is rotatably connected with a fixing ring 411 , and the interior of the fixing ring 411 is communicated with the interior of the annular ventilation groove 405 .

[0050] The inner and outer walls of the fixing ring 411 are fixedly connected with an arc-shaped telescopic rod 406, which is a multi-section arc-shaped rod-shaped structure. The lifting slider 402 and the outer walls of the magnetic plate 403 are inclined surfaces. One end of the arc-shaped telescopic rod 406 and the inner wall of the magnetic groove 407 are magnetic, and the magnetism of the arc-shaped telescopic rod 406 and the magnetic groove 407 on the opposite side is that the opposite poles attract each other. The outer wall of the magnetic plate 403 and the inner wall of the sliding groove 401 are magnetic, and the magnetism of the outer wall of the magnetic plate 403 and the inner wall of the sliding groove 401 on the opposite side is that the opposite poles attract each other.

[0051] When the wire drum 302 is driven to rotate rapidly, the lifting slider 402 and the magnetic plate 403 in the sliding groove 401 inside the rotating wire drum 302 will also be thrown outward due to the centrifugal force. Because the lifting slider 402 and the magnetic plate 403 are not vertically arranged inside the sliding groove 401, but inclined, when the magnetic plate 403 and the lifting slider 402 below are subjected to an outward force, an upward component of force will be applied through the inclined shape of the inner wall of the sliding groove 401 to push them upward, and when the lifting slider 402 and the magnetic plate 403 above are subjected to an outward force, a downward component of force will be applied through the inclined sliding groove 401 to push them downward, and the magnetic plate 403 will be separated from the inner wall of the sliding groove 401. The magnetic attraction at the bottom of the wall quickly pushes out, and the upper and lower lifting sliders 402 and the magnetic plate 403 are squeezed toward the middle, and the lifting slider 402 slides on the fixed slide bar 410, which pushes the annular bearing 408 and the lifting scraper 409 to lift vertically, so that the upper and lower annular bearings 408 and the lifting scraper 409 are close to each other and push the cable in the middle, so as to achieve the close contact and bundling effect of the cable. The faster the cable transmission speed is, the faster the rotation speed of the cable drum 302 is, and the greater the pressure of the annular bearings 408 pushing the cable against each other is, so that the cable can be more tightly bound at a faster transmission speed, and the problem of cable tangling can be adaptively prevented;

[0052] When the annular bearing 408 is lifted or lowered, the lifting scraper 409 is driven to lift or lower, and the outer wall of the annular groove 304 is lifted or lowered synchronously to scrape and move, thereby achieving a full cleaning effect on the annular groove 304 and preventing the adhesion of residues. When the lifting slider 402 and the magnetic plate 403 are lifted or lowered to squeeze the air in the sliding groove 401, the air is squeezed into the vent hole 404 through the magnetic plate 403, and then enters the annular vent groove 405 through the vent hole 404, and then enters the fixing ring 405 through the annular vent groove 405. 11, and push the arc telescopic rod 406 in the fixing ring 411, so that the arc telescopic rod 406 is pushed out, and because the fixing ring 411 is fixed by the inner wall of the wire releaser 2, it cannot rotate, and at the same time, the inside of the arc telescopic rod 406 is pushed by the air to expand and retract, and the multi-section arc telescopic rod is pushed out to fully cover the cable in the annular groove 304 and keep it stationary, so as to prevent the problem of cable derailment and disordered wires, further protect the cable during transmission, and effectively improve the efficiency and stability of cable transmission;

[0053] Even if the rotation speed is slow, the arc-shaped telescopic rod 406 and the magnetic groove 407 will be magnetically attracted to each other and will not separate. Only when the rotation speed of the line disk 302 drops significantly and the centrifugal force pushes the lifting slider 402 and the magnetic plate 403 to reduce the sliding distance, the arc-shaped telescopic rod 406 will be pulled back to its original position by the air pressure. The force pulling the arc-shaped telescopic rod 406 is greater than the magnetic attraction between the magnetic groove 407 and the arc-shaped telescopic rod 406, so it will separate. When rotating quickly, even if the rotation speed is reduced a little, the arc-shaped telescopic rod 406 will maintain magnetic attraction with the magnetic groove 407 and will not separate.

[0054] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
