Description

Technical Field

[0001] This application belongs to the technical field of cable puller equipment, specifically a cable puller for power engineering. Background Technology

[0002] Cable pullers are indispensable auxiliary tools in electrical construction, decoration wiring, and pipeline maintenance. They are primarily used to solve the problem of pulling cables such as electrical wires, network cables, and fiber optic cables through narrow or concealed spaces such as wall pipes, ceiling cavities, and cable trays. The tool typically consists of a high-toughness guide head, a high-strength flexible body, and a handle. To use it, first push or pull the flexible guide head through the channel to be wired by hand, then fix the cable to the guide head, and finally pull the body in the opposite direction to easily pull the cable to the target location.

[0003] Referring to CN214779922U, a wire threading device for power engineering relates to the field of power engineering technology. It improves upon the cumbersome process of cleaning guide ropes. The device includes a frame, a base, a support frame mounted on the base, and a winding reel rotatably connected to the support frame. A guide rope is wound in the winding reel. The base has a water tank with an opening at its upper end. The base contains a guiding component for guiding the guide rope to the water tank, and the water tank has a pressing component for pressing the guide rope into the water tank. The base also includes a water removal component. This application facilitates the cleaning of recovered guide ropes.

[0004] However, the following problems still exist: the existing cable guide device has great limitations and needs to be freely adjusted according to the actual cable pulling needs. When the cable guide position is excessively deflected, the entire cable puller needs to be moved. At the same time, when the turning range is large, the cable is easy to scrape the edge of the guide device, which makes adjusting the cable time-consuming and laborious and easily causes cable damage. Utility Model Content

[0005] The purpose of this application is to address the limitations of existing cable guiding devices, which require free adjustment of the cable guiding position according to actual cable pulling needs. When the cable deflects excessively, the entire cable puller needs to be moved. At the same time, when the turning range is large, the cable is prone to scraping against the edge of the guiding device, resulting in time-consuming and laborious cable adjustment and easy damage to the cable. The application provides a cable puller for power engineering.

[0006] The technical solution adopted in this application is as follows: A cable puller for power engineering includes a support plate, a rotating column rotatably connected to the back of the support plate, a bracket fixedly fitted on the surface of the rotating column, a cable being installed inside the bracket, a roller rotatably connected to the front of the support plate, a horizontal plate fixedly connected to the side of the support plate, a support cylinder rotatably connected to the upper surface of the horizontal plate, a lifting component fixedly connected to the upper surface of the support cylinder, a concave plate fixedly connected to the top of the lifting component, a horizontal cylinder rotatably connected to the inner wall of the concave plate, a vertical rod rotatably connected to the bottom wall of the inner wall of the concave plate, a vertical cylinder fixedly fitted on the surface of the vertical rod, a limiting plate fixedly connected to the upper surface of the horizontal plate, a rotating rod rotatably connected to the upper surface of the limiting plate, a limiting component fixedly fitted on the surface of the rotating rod, and a locking tooth fixedly fitted on the surface of the support cylinder.

[0007] Preferably, the lifting component includes a cylinder, the bottom end of which is fixedly connected to the upper surface of the support cylinder. A telescopic rod is slidably connected to the inner wall of the cylinder, and the top end of the telescopic rod is fixedly connected to the lower surface of the concave plate. A fixing hole is provided on the surface of the telescopic rod, and a threaded fixing rod is threadedly connected to the inner wall of the fixing hole. The end of the threaded fixing rod near the telescopic rod passes through the surface of the cylinder. First, the threaded fixing rod is rotated, and the threaded fixing rod rotates away from the fixing hole, thus canceling the limitation on the telescopic rod. Then, the telescopic rod is pulled, and the telescopic rod pushes the concave plate to move upward. The upward movement of the concave plate causes one end of the cable to move upward until the cable is moved to the required threading height. Then, the telescopic rod is stopped from being pulled. Then, the threaded fixing rod is rotated again, and the threaded fixing rod rotates to fix the telescopic rod using the fixing hole.

[0008] Preferably, the limiting component includes a snap-fit ​​plate, which is fixedly sleeved on the surface of the vertical cylinder. A spring is fixedly connected to the front of the snap-fit ​​plate, and a rectangular cylinder is fixedly connected to the upper surface of the horizontal plate. The end of the spring away from the snap-fit ​​plate is fixedly connected to the inner wall of the rectangular cylinder. A pull rod is fixedly connected to the side of the snap-fit ​​plate away from the limiting plate, which pushes the lifting component to rotate clockwise. When the lifting component rotates, it drives the support cylinder to rotate. The rotation of the support cylinder then drives the locking teeth to rotate, and the rotation of the locking teeth pushes the snap-fit ​​plate to rotate.

[0009] Preferably, a limiting cylinder is fixedly connected to the side of the snap-fit ​​plate near the rectangular cylinder. The limiting cylinder is sleeved on the surface of the spring. By setting the limiting cylinder, the occurrence of spring displacement can be reduced when the spring is compressed.

[0010] Preferably, a pull rod is fixedly connected to the front of the concave plate. The pull rod is symmetrically arranged on both sides of the concave plate with the vertical center line of the side of the concave plate as the axis of symmetry. By setting two pull rods, it is convenient for the user to pull the concave plate to rotate from two different opposite directions.

[0011] Preferably, a push rod is fixedly connected to the front of the support plate. By setting the push rod, the user can easily push the support plate, and then move the support plate with the help of rollers, which facilitates the handling of the support plate.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0013] 1. In this application, the cable is first pulled, at which point the bracket rotates and continuously releases the cable. Then, the cable is pulled through the gap between the horizontal and vertical cylinders. Next, the lifting component is adjusted, which pushes the concave plate up or down. The movement of the concave plate causes the vertical and horizontal cylinders to move upwards, which in turn causes the cable to move upwards, adjusting the cable threading height. Then, the pull rod is pushed, which pushes the concave plate and the lifting component. At this time, the lifting component rotates, which in turn causes the concave plate, the horizontal cylinder, and the vertical cylinder to rotate. The rotation of the vertical cylinder then causes the cable to rotate until the cable is adjusted to the required threading position. Then, the lifting component is stopped, thus enabling the device to facilitate the adjustment of the cable threading position while avoiding cable damage. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] Example:

[0021] Reference Figure 2-3 A cable puller for power engineering includes a support plate 1, a rotating column 3 rotatably connected to the back of the support plate 1, a bracket 4 fixedly fitted on the surface of the rotating column 3, a cable 5 disposed inside the bracket 4, a roller 2 rotatably connected to the front of the support plate 1, a horizontal plate 7 fixedly connected to the side of the support plate 1, a support cylinder 12 rotatably connected to the upper surface of the horizontal plate 7, a lifting component 11 fixedly connected to the upper surface of the support cylinder 12, a concave plate 8 fixedly connected to the top of the lifting component 11, a horizontal cylinder 9 rotatably connected to the inner wall of the concave plate 8, a vertical rod 20 rotatably connected to the bottom wall of the inner wall of the concave plate 8, a vertical cylinder 17 fixedly fitted on the surface of the vertical rod 20, the horizontal cylinder 9 and the vertical cylinder 17 fitting against the surface of the cable 5, and a locking tooth 15 fixedly fitted on the surface of the support cylinder 12. When the cable 5 is pulled, the horizontal cylinder 9 and the vertical cylinder 17 rotate along the cable 5, making it easier for the user to pull the cable 5 and avoiding the situation where the cable 5 is difficult to pull when bent, while reducing the cable 5's bending. To address the issue of wear and damage to the outer sheath during pulling, a limiting plate 14 is fixedly connected to the upper surface of the horizontal plate 7. A rotating rod 13 is rotatably connected to the upper surface of the limiting plate 14, and a limiting component 16 is fixedly sleeved on the surface of the rotating rod 13. When the cable 5 is pulled, the bracket 4 rotates, continuously releasing the cable 5. Then, the cable 5 is pulled through the gap between the horizontal cylinder 9 and the vertical cylinder 17. Next, the lifting component 11 is adjusted, which pushes the concave plate 8 to rise or fall. The movement of the concave plate 8 causes the vertical cylinder 17 and the horizontal cylinder 9 to move upward, which in turn causes the cable 5 to move upward, adjusting the threading height of the cable 5. Then, the pull rod 10 is pushed, which pushes the concave plate 8 and the lifting component 11. At this time, the lifting component 11 rotates, which in turn causes the concave plate 8, the horizontal cylinder 9, and the vertical cylinder 17 to rotate. The rotation of the vertical cylinder 17 then causes the cable 5 to rotate until the cable 5 is adjusted to the required threading position, at which point the lifting component 11 is stopped.

[0022] Reference Figure 1-3The lifting component 11 includes a cylinder 111. The bottom end of the cylinder 111 is fixedly connected to the upper surface of the support cylinder 12. A telescopic rod 113 is slidably connected to the inner wall of the cylinder 111. The top end of the telescopic rod 113 is fixedly connected to the lower surface of the concave plate 8. A fixing hole 114 is opened on the surface of the telescopic rod 113. A threaded fixing rod 112 is threadedly connected to the inner wall of the fixing hole 114. One end of the threaded fixing rod 112 near the telescopic rod 113 penetrates the surface of the cylinder 111. First, rotate the threaded fixing rod 112. 12. Rotate away from the fixing hole 114 to release the limit on the telescopic rod 113. Then pull the telescopic rod 113. The telescopic rod 113 pushes the concave plate 8 upward. The upward movement of the concave plate 8 causes one end of the cable 5 to move upward until the cable 5 is brought to the required threading height. Stop pulling the telescopic rod 113. Then rotate the threaded fixing rod 112 again. The threaded fixing rod 112 rotates and uses the fixing hole 114 to fix the telescopic rod 113. The limiting component 16 includes a snap-fit ​​plate 161, which is fixedly sleeved on the surface of the vertical cylinder 17. On the front of the snap-fit ​​plate 161, a spring 162 is fixedly connected. A rectangular tube 19 is fixedly connected to the upper surface of the horizontal plate 7. The end of the spring 162 away from the snap-fit ​​plate 161 is fixedly connected to the inner wall of the rectangular tube 19. A push handle 163 is fixedly connected to the side of the snap-fit ​​plate 161 away from the limiting plate 14. Pushing the lifting component 11 to rotate clockwise causes the support tube 12 to rotate. The rotation of the support tube 12 then causes the locking teeth 15 to rotate. The rotation of the locking teeth 15 pushes the snap-fit ​​plate 161 to rotate. The spring 162 is compressed until the locking plate 161 passes through one of the locking teeth 15. At this time, the limiting component 16 resets and pushes the locking plate 161 to rotate back to its original position and lock onto the locking tooth 15 again. When it is necessary to rotate the lifting component 11 in the opposite direction, the locking plate 161 is pulled away from the locking tooth 15 by the push handle 163. Then, the lifting component 11 is pushed counterclockwise to rotate. After adjusting to a suitable position, the push handle 163 is released. At this time, the spring 162 pushes the locking plate 161 to rotate back to its original position and limits the locking tooth 15 again.

[0023] Reference Figure 2-3 The snap-fit ​​plate 161 is fixedly connected to the limiting cylinder 18 on the side near the rectangular cylinder 19. The limiting cylinder 18 is sleeved on the surface of the spring 162. By setting the limiting cylinder 18, the occurrence of spring 162 displacement can be reduced when the spring 162 is compressed.

[0024] Reference Figure 1-2 A pull rod 10 is fixedly connected to the front of the concave plate 8. The pull rod 10 is symmetrically arranged on both sides of the concave plate 8 with the vertical center line of the side of the concave plate 8 as the axis of symmetry. By setting two pull rods 10, it is convenient for the user to pull the concave plate 8 to rotate from two different opposite directions.

[0025] Reference Figure 2-3A push rod 6 is fixedly connected to the front of the support plate 1. By setting the push rod 6, the user can easily push the support plate 1, and then move the support plate 1 with the help of the roller 2, which makes it easy to move the support plate 1.

[0026] The implementation principle of a cable puller embodiment for power engineering in this application is as follows: First, pull the cable 5. At this time, the bracket 4 rotates, continuously releasing the cable 5. Then, pull the cable 5 through the gap between the horizontal cylinder 9 and the vertical cylinder 17. Next, adjust the lifting component 11. The lifting component 11 pushes the concave plate 8 up or down. The movement of the concave plate 8 causes the vertical cylinder 17 and the horizontal cylinder 9 to move upward. The upward movement of the vertical cylinder 17 and the horizontal cylinder 9 causes the cable 5 to move upward, adjusting the cable 5's threading height. Then, push the pull rod 10. The pull rod 10 pushes the concave plate 8 and the lifting component 11. At this time, the lifting component 11 rotates. The rotation of the lifting component 11 causes the concave plate 8, the horizontal cylinder 9, and the vertical cylinder 17 to rotate. The rotation of the vertical cylinder 17 then causes the cable 5 to rotate until the cable 5 is adjusted to the required threading position. Then, stop pushing the lifting component 11. Thus, the device has the effect of facilitating the adjustment of the cable threading position while avoiding cable damage.
