[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] Reference Figure 1 and Figure 2, a vertical hanging cable spreader includes a hanging frame 1, a hanging ring 2 is fixedly connected to the top of the hanging frame 1, the hanging ring 2 is used to provide a hanging point for the spreader, which is convenient for the lifting and operation of the whole spreader, and a hanging rod 3 is fixedly connected to the top of the hanging ring 2. The hanging rod 3 serves as a load-bearing connection part and can bear the weight of the spreader and ensure the stability of the spreader. A circular ring 4 is fixedly connected to the top of the hanger rod 3, and a fixed column 6 is fixedly connected to the inside of the circular ring 4. The outer wall of the fixed column 6 is provided with an anti-falling component, which is used to hang the spreader to ensure that the spreader is not easy to fall off during use;
[0025] The anti-falling component includes a hook 5 and a pad 8. The hook 5 is rotatably connected to the outer wall of the fixed column 6. One side of the pad 8 is fixedly connected to the outer wall of the hook 5. One side of the pad 8 is fixedly connected to the outer wall of the hook 5. The pad 8 plays a supporting and buffering role. The hook 5 is rotatably connected to the rotating column 10 inside, and the outer wall of the rotating column 10 is rotatably connected to the rebound pin 7. The function of the rebound pin 7 is to realize the automatic return function of the hook 5. A spring 9 is arranged between the rebound pin 7 and the pad 8. One end of the spring 9 is fixedly connected to one side of the rebound pin 7, and the other end of the spring 9 is fixedly connected to the outer wall of the pad 8. A clamping component is arranged inside the hanging frame 1. The clamping component is used to clamp the cable. The function of the clamping component is to automatically adjust according to the size of the cable and tightly clamp the cable.
[0026] Specifically, when it is necessary to hang the vertically laid cable hanger on the traction rope, the rebound pin 7 is first squeezed by the traction force of the traction rope, so that the rebound pin 7 is pressed toward the inside of the hook 5. During this process, the rebound pin 7 rotates under the guidance of the rotating column 10, and is accompanied by displacement. When the rebound pin 7 is displaced, the extrusion force applied to the spring 9 causes the spring 9 to deform and shrink toward the inside of the hook 5, forming a temporary compressed state. As the traction rope gradually slides down and enters the inside of the hook 5, the spring 9 will quickly restore its elasticity and release the stored energy with the help of the support force provided by the pad 8. At this time, the restoring force of the spring 9 causes the rebound pin 7 to quickly rebound to its original position, thereby realizing the reliable collection and fixation of the traction rope. Through this design, the traction rope and the hanger are prevented from falling off, ensuring the stability and safety of the cable hanger during the lifting operation.
[0027] Reference Figure 3 and Figure 4The clamping assembly includes a motor 11 and a rotating disk 15. The rotating disk 15 is a key transmission component that transmits the rotational motion of the motor 11 to the subsequent mechanical structure. The bottom of the motor 11 is fixedly connected to the inside of the hanging frame 1. One side of the rotating disk 15 is fixedly connected to the output end of the motor 11. One end of the rotating disk 15 is rotatably connected to a crank 16, and the other end of the rotating disk 15 is rotatably connected to a crank 2 17. Crank 16 and crank 2 17 respectively convert the rotational motion of the rotating disk 15 into linear displacement, pushing the subsequent components to perform displacement and clamping actions. One end of the crank 2 17 is rotatably connected to a sliding block 19. The outer wall of the sliding block 19 is fixedly connected to a clamping block 18. The interior of the hanging frame 1 is fixedly connected to a slide rail 2 0. A slide groove 21 is provided inside the slide rail 20. The sliding block 19 moves horizontally under the guidance of the slide rail 20. The sliding block 19 is slidably connected to the inside of the slide groove 21. The bottom of the clamping block 18 is fixedly connected to the outer wall of the sliding block 19. Through the movement of the sliding block 19, the clamping block 18 can apply a uniform clamping force to the cable to ensure the fixing effect of the cable in the sling. The outer wall of the hanging frame 1 is fixedly connected to the support block 12. The support block 12 is rotatably connected to the support column 14 inside. The outer wall of the support column 14 is fixedly connected to the rotating roller 13. The contact between the rotating roller 13 and the outer wall of the sling can effectively reduce friction and reduce the resistance encountered by the sling during the hanging process. At the same time, it can buffer vibration and ensure the smooth operation of the sling.
[0028] Specifically, when the cable passes vertically through the laying spreader, the motor 11 is started, and the output end of the motor 11 drives the rotating disk 15 to rotate. The rotation of the rotating disk 15 causes the crank 16 and the crank 2 17 at both ends to move. In particular, the movement of the crank 2 17 drives the sliding block 19 to move parallel to the slide groove 21 in the slide rail 20. The horizontal movement of the sliding block 19 further pushes the clamping block 18 to move closer to the center position of the spreader, thereby firmly clamping cables of different sizes and achieving reliable fixation of the cables. As the spreader continues to descend vertically and lay the cables, one side of the spreader begins to slide along the wall of the building, and is in close contact with the wall through the rotating roller 13, thereby effectively reducing friction resistance and alleviating vibration. This design not only optimizes the stability of the cable laying process, but also helps to improve work efficiency and reduce possible mechanical damage, thereby ensuring the safe transportation and fixation of the cables.
[0029] Working principle: When it is necessary to hang the vertical cable spreader on the traction rope, first squeeze the rebound pin 7 through the traction rope, press the rebound pin 7 into the hook 5, so that the rebound pin 7 rotates on the rotating column 10 and displaces at the same time. When the rebound pin 7 is displaced, it will squeeze the spring 9. At this time, the spring 9 deforms and contracts toward the inside of the hook 5. Then, when the traction rope slides into the hook 5 by squeezing the rebound pin 7, the spring 9 releases it with the help of the elastic force stored in the position of the pad 8. The elastic force of the spring 9 is released to make the rebound pin 7 rebound and reset, thereby achieving the purpose of taking the traction rope and preventing the traction rope and the spreader from falling off. When the cable passes vertically into the laying spreader, it is then started The motor 11 is driven, and the output end of the motor 11 drives the rotating disk 15 to rotate. The rotation of the rotating disk 15 drives the crank 16 and the crank 2 17 at both ends to be displaced. The movement of the crank 2 17 drives the sliding block 19 to move. At the same time, the sliding block 19 moves the slide groove 21 opened inside the slide rail 20. The parallel movement of the sliding block 19 drives the clamping block 18 to move to the middle position of the spreader, thereby clamping cables of different sizes, achieving the effect of clamping and fixing the cables. When the spreader is hanging and laying cables, one side of the spreader moves along the wall of the building. At this time, the rotating roller 13 is in contact with the wall, thereby achieving the effect of reducing resistance and buffering vibration.
