Description

Technical Field

[0001] This utility model relates to the field of power equipment, specifically a cable puller. Background Technology

[0002] Cables are typically rope-like structures made up of several or groups of conductors twisted together. Each group of conductors is insulated from each other and is often twisted around a central core. The entire cable is covered with a highly insulating outer layer. They are mostly installed in the air, underground, or underwater for telecommunications or power transmission. Currently, when manufacturing cables, each cable is hundreds or thousands of meters long. If they are stacked haphazardly, they are prone to knotting and take up a lot of space, making stacking and use inconvenient and transportation difficult. Therefore, they are now usually wound in several loops around a cable puller.

[0003] According to Chinese Patent No. CN219489208U, a wire and cable puller is disclosed. After the wire or cable is wound on the puller, the tilting block can be adjusted to correspond to the movable end of the cable by moving the slide on the guide rail seat. Then, one end of the tilting block is locked on the locking seat to ensure the cable's fixation and prevent the wound cable from becoming loose. This is beneficial for the later use of the wire or cable.

[0004] Regarding the aforementioned patent content, an annular retainer is provided to fix one end of the cable in place. However, when the cable end is clamped in the annular retainer, the annular retainer has difficulty applying pressure to the cable end, resulting in poor stability of the cable end clamped in the annular retainer. This makes it easy for the cable end to fall off the retainer, thereby reducing the clamping and fixing efficiency of the cable end. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a cable puller to solve the technical problem that the cable end stability is poor due to the method of clamping the cable with a ring-shaped clamp.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cable puller, comprising a base plate and a clamping seat, wherein the clamping seat is provided with a clamping assembly, and the clamping assembly includes a fixed seat installed on the back of the clamping seat and connecting seats provided on both sides of the outer surface of the clamping seat. A clamping plate is rotatably connected to the connecting seat. A sliding groove is provided on the top of the fixed seat.

[0013] By adopting the above technical solution, when the roller needs to rotate, the motor can be started, and the motor can drive the drive shaft to rotate, thereby driving the roller to rotate.

[0014] Furthermore, a movable shaft is connected to one side of the second vertical plate via a bearing. Both one end of the movable shaft and one end of the drive shaft are provided with slots, and a retaining plate is engaged inside the slots.

[0015] By adopting the above technical solution, the card plate is designed to be easily inserted into the card slot, which facilitates the installation of the rotating roller.

[0016] Furthermore, a rotating roller is installed between the two clamping plates, and locking bolts extending into the interior of the clamping plates are installed on both the movable shaft and the drive shaft, with a limiting nut at the bottom of the locking bolt.

[0017] By adopting the above technical solution, when the locking bolt is screwed into the inside of the card plate, the card plate can be locked and limited to prevent it from falling out of the card slot.

[0018] Furthermore, two fixing plates are also installed on the top of the base plate. One side of one fixing plate is connected to a threaded rod via a bearing, and one end of the threaded rod passes through the other fixing plate and is connected to a rotating handle.

[0019] By adopting the above technical solution, it is convenient for workers to rotate the threaded rod through the handle, and the rotation of the threaded rod will drive the movable seat to move.

[0020] Furthermore, a movable seat is sleeved on the outer wall of the threaded rod, and a retaining seat is installed on the top of the movable seat. The movable seat is threadedly connected to the threaded rod.

[0021] By adopting the above technical solution, when the threaded rod rotates, it can drive the movable seat to move, and then drive the clamping seat to move, so as to adjust the position of the clamping seat.

[0022] Furthermore, a guide rod is installed between the two fixed plates, and the guide rod passes through the movable seat.

[0023] By adopting the above technical solution, the guide rod can guide the movable seat, prevent the movable seat from rotating, and improve the stability of the movable seat when it moves.

[0024] Furthermore, the clamping plate is arc-shaped, and the outer wall of the slide block fits against the inner wall of the slide groove.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0037] The embodiments of this utility model will be described below based on its overall structure.

[0038] Example 1:

[0039] A cable puller, such as Figures 1-6 As shown, the device includes a base plate 1 and a mounting base 16. The mounting base 16 is equipped with a clamping assembly 9. A first vertical plate 2 and a second vertical plate 3 are respectively installed on the top of the base plate 1. A motor 4 is installed on one side of the first vertical plate 2, and the output end of the motor 4 is connected to a drive shaft 5. When the roller 11 needs to rotate, the motor 4 can be started. The operation of the motor 4 can drive the drive shaft 5 to rotate, thereby driving the roller 11 to rotate. A movable shaft 6 is connected to one side of the second vertical plate 3 through a bearing. A slot 7 is opened at one end of the movable shaft 6 and one end of the drive shaft 5. A clamping plate 8 is clamped inside the slot 7. The roller 11 is installed between the two clamping plates 8. The clamping plates 8 are designed to be easily inserted into the slot 7, thereby facilitating the installation of the roller 11.

[0040] See Figures 1-3 Two fixed plates 12 are also installed on the top of the base plate 1. One side of the fixed plate 12 is connected to a threaded rod 13 via a bearing, and one end of the threaded rod 13 passes through the other fixed plate 12 and is connected to a handle, so that the operator can rotate the threaded rod 13 by rotating the handle. After the threaded rod 13 rotates, it will drive the movable seat 15 to move. The movable seat 15 is sleeved on the outer wall of the threaded rod 13. A retaining seat 16 is installed on the top of the movable seat 15. The movable seat 15 is threadedly connected to the threaded rod 13. When the threaded rod 13 rotates, it can drive the movable seat 15 to move, and then drive the retaining seat 16 to move, so as to adjust the position of the retaining seat 16.

[0041] Specifically, the clamping assembly 9 includes a fixed seat 901 installed on the back of the card holder 16 and connecting seats 907 provided on both sides of the outer surface of the card holder 16. A clamping plate 908 is rotatably connected to the connecting seat 907. A sliding groove 902 is provided on the top of the fixed seat 901. A threaded shaft 903 is connected to the inside of the sliding groove 902 through a bearing. A sliding block 904 is sleeved on the outer wall of the threaded shaft 903. A connecting plate 905 is installed on both sides of the sliding block 904. A pull plate 906 is connected between the connecting plate 905 and the clamping plate 908 through a rotating shaft. When the connecting plate 905 moves, it will drive the pull plate 906 to rotate. The pull plate 906 can drive the clamping plate 908 to rotate so that the clamping plate 908 can clamp the end of the cable.

[0042] See Figure 2 , Figure 4 , Figure 5 and Figure 6 The slide 904 is threadedly connected to the threaded shaft 903. One end of the threaded shaft 903 extends through to the outside of the fixed seat 901 and is connected to a knob so that the rotation of the threaded shaft 903 can drive the slide 904 to move. The movement of the slide 904 will drive the connecting plate 905 to move. The clamping plate 908 is arc-shaped. The outer wall of the slide 904 fits against the inner wall of the slide groove 902. The clamping plate 908 can clamp one end of the cable, thereby improving the stability of the cable and preventing the cable from becoming looser after winding. The inner wall of the clamping plate 908 is equipped with a protective pad 909. The protective pad 909 is made of rubber material and can protect the end of the cable, preventing the clamping plate 908 from directly contacting the end of the cable and causing damage to the end of the cable.

[0043] Example 2:

[0044] Based on the above embodiment 1, in order to prevent the card plate 8 from falling out of the card slot 7, it is necessary to lock and limit the card plate 8. Therefore, the following structure will be set.

[0045] Specifically, locking bolts 10 extending into the interior of the clamping plate 8 are installed on both the movable shaft 6 and the drive shaft 5, and a limiting nut 17 is provided at the bottom of the locking bolt 10. When the locking bolt 10 is screwed into the interior of the clamping plate 8, the clamping plate 8 can be locked and limited to prevent the clamping plate 8 from falling out of the clamping groove 7.

[0046] Example 3:

[0047] Based on the above embodiment 1, in order to improve the stability of the movable seat 15 and prevent the movable seat 15 from rotating, the following structure will be set.

[0048] See Figure 1A guide rod 14 is installed between the two fixed plates 12. The guide rod 14 passes through the movable seat 15 and is located below the threaded rod 13. The guide rod 14 can guide the movable seat 15, prevent the movable seat 15 from rotating, and improve the stability of the movable seat 15 when it moves.

[0049] The working principle of this utility model is as follows: First, when in use, the wire or cable is wound on the traction device. After the cable is wound, the operator can rotate the threaded rod 13 to move the movable seat 15. The movable seat 15 then drives the clamping seat 16 to move, so that the clamping seat 16 can correspond to the movable end of the cable. Then, one end of the cable is placed between the two clamping plates 908. Next, the operator rotates the threaded shaft 903. After the threaded shaft 903 rotates, it will drive the slide 904 to move. The slide 904 will then drive the connecting plate 905 to move. When the connecting plate 905 moves, it will drive the pull plate 906 to rotate. The pull plate 906 can drive the clamping plate 908 to rotate so that the clamping plate 908 can clamp the end of the cable and improve the stability of the cable.

[0050] When it is not necessary to clamp the cable end, the threaded shaft 903 can be rotated in the opposite direction to reset the slide 904 and drive the connecting plate 905 to reset. The pull plate 906 then pulls the clamping plate 908 to rotate, so that the clamping plate 908 no longer clamps the cable end.
