A first annular groove is provided on the outside of the cable puller. A limiting slider is provided inside the limiting groove. The bottom of the cable puller is connected to the limiting slider. Support platforms are provided on both sides of the limiting groove. A rotating wheel is provided on the outer side of the end of the support platform. A second annular groove is provided on the outer side of the rotating wheel.

[0004] The search revealed that the device only supports clamping the wire along a single axis and cannot achieve multi-directional adjustment of horizontal, vertical or tilt angles. When the installation space is narrow or the wire needs to go around obstacles, an additional steering bracket is required, increasing the number of tools and operating steps. The device uses an arc-shaped cover plate and bolts to clamp the steel strand, which requires additional manual operation and has certain limitations on the specifications of the steel strand that can be clamped, making the device less adaptable.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0008] In a preferred embodiment of this utility model, a slider is threaded onto each end of the bidirectional lead screw, and the two sliders are respectively fixedly connected to a rocker arm and a main rod.

[0009] In a preferred embodiment of this utility model, a sleeve is provided at one end of the swing rod, and the sleeve is hinged to one end of the main rod through a damping bearing, and a rotating wheel is rotatably connected inside the sleeve.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0019] A type of power cable assembler, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, including Mounting base 10, on which a bidirectional lead screw 13 is rotatably mounted, and at each end of the bidirectional lead screw 13 is a guide mechanism, and the two guide mechanisms together clamp a steel strand 17. The guide mechanism is provided with a braking mechanism for limiting the direction of the pull wire. The guiding mechanism includes a pull wheel 16, a rotating wheel 18, a rocker arm 19, and a main rod 20. The main rod 20 is slidably disposed in the mounting base 10. One end of the main rod 20 is hinged to the rocker arm 19. A pull wheel 16 is rotatably disposed on the rocker arm 19 and the main rod 20 respectively. A rotating wheel 18 is rotatably disposed at the hinge point between the rocker arm 19 and the main rod 20. The two sets of guiding mechanisms clamp the steel strand 17 through the corresponding pull wheels 16 and rotating wheels 18. The braking mechanism includes a ratchet 21 and a pawl 24. The ratchet 21 is fixedly mounted on the bottom of the pull wheel 16. A pawl 24 is movably mounted on the swing arm 19 and the main rod 20 respectively. The swing arm 19 and the main rod 20 lock and limit the ratchet 21 through the corresponding pawl 24.

[0020] Specifically, this device incorporates a guiding mechanism and a braking mechanism. The two guiding mechanisms can axially clamp the steel strand 17 via a bidirectional lead screw 13. Combined with the multi-angle hinge of the swing arm 19 and the main rod 20, it meets the bending and turning requirements of the steel strand 17 during pulling, making the device adaptable to complex working conditions such as narrow spaces and obstacle avoidance, thereby reducing the amount of auxiliary tools required. The bidirectional lead screw 13 drives the guide mechanism to clamp the steel strand 17 quickly, avoiding uneven force issues caused by manual operation. The multiple fastening of the pull wheel 16 and the rotating wheel 18 can accommodate various specifications of steel strand 17 without requiring a complete equipment replacement. The braking mechanism achieves one-way locking of the steel strand 17, statically placing the steel strand 17 during return, improving the adaptability of the device while enhancing the stability of the clamping.

[0021] like Figure 1 As shown, a groove 14 is provided at the center of the top surface of the mounting base 10. The bidirectional lead screw 13 is rotatably fitted into the groove 14 through a bearing. A motor base 11 is fixedly installed on one side of the mounting base 10. A coupling is installed in the motor base 11. A servo motor 12 is fixedly installed on the side of the motor base 11 away from the mounting base 10. The output end of the servo motor 12 is connected to the bidirectional lead screw 13 through a coupling. The servo motor 12 is fixed to the outside of the motor base 11 by bolts. Its output shaft is rigidly connected to the bidirectional lead screw 13 through a coupling to ensure that the power transmission is backlash-free. like Figure 1 , Figure 2 and Figure 3 As shown, the two ends of the bidirectional lead screw 13 are machined with left-hand and right-hand threads. A slider 15 is threaded on each end of the bidirectional lead screw 13. The two guide mechanisms are oriented in different directions and are arranged around the bidirectional lead screw 13 at a 180-degree angle. The two sliders 15 are respectively fixedly connected to a rocker arm 19 and a main rod 20 to ensure that the two guide mechanisms can move synchronously in opposite directions along the slide groove 14. like Figure 3 As shown, a sleeve is provided at one end of the swing rod 19. The sleeve is hinged to one end of the main rod 20 through a damping bearing. A rotating wheel 18 is rotatably connected inside the sleeve. The length of the swing rod 19 is longer than that of the main rod 20. The diameter of the rotating wheel 18 is larger than that of the pull wheel 16 to ensure that the steel strand 17 is subjected to balanced force when bending. The bottom of the rotating wheel 18 is rotatably connected to the sleeve through a rotating shaft.

[0022] The working principle is as follows: After receiving the control signal, the servo motor 12 rotates forward, driving the bidirectional lead screw 13 to rotate through the coupling. The two sliders 15 move towards each other along the slide groove 14, driving the pull wheels 16 and rotating wheels 18 of the two sets of guide mechanisms to gradually approach each other until they match the specifications of the steel strand 17 and clamp the steel strand 17. In another state, when the steel strand 17 is bent, the swing arm 19 can be manually rotated around the main rod 20 by means of the damping bearing hinge structure between the swing arm 19 and the main rod 20. It should be noted that the other guide mechanism requires manual rotation of the main rod 20 around the swing arm 19. That is, the side fixed to the slider 15 is the fixed end, and the other side is the rotating end, so that the steel strand 17 bends along the curved surface of the rotating wheel 18 to meet the installation requirements of horizontal, vertical or inclined directions. At the same time, the damping bearing used in this device needs to be lubricated regularly, and the friction torque of the damping bearing ensures that the swing arm 19 can maintain a fixed angle when there is no external force.

[0023] like Figure 3 , Figure 4 and Figure 5 As shown, the pull wheel 16 and the rotating wheel 18 have the same shape but different sizes. The middle curved surface of both the pull wheel 16 and the rotating wheel 18 is provided with an arc-shaped annular groove. The arc-shaped annular groove is used to fit the arc-shaped surface of the steel strand 17. The surface of the arc-shaped annular groove is provided with anti-slip texture to prevent the steel strand 17 from detaching during the pulling process. The swing rod 19 and the main rod 20 are provided with a rotating hole 22 and a braking hole 23 at their opposite ends. The rotating hole 22 and the braking hole 23 are perpendicularly intersecting and communicating. The ratchet 21 is rotatably installed in the braking hole 23 through a bearing. The ratchet 21 is coaxially fixed with the pull wheel 16. The pawl 24 is rotatably installed in the rotating hole 22. like Figure 4 and Figure 5 As shown, the rotating hole 22 is shaped like an I-beam, and an I-beam shaped rotating shaft sleeve 26 is rotatably installed inside the rotating hole 22. The pawl rod 24 slides through the rotating shaft sleeve 26, and the pull wheel 16 locks and limits the ratchet wheel 21 through the pawl rod 24. like Figure 5 As shown, the pawl lever 24 consists of a nail-shaped lever and a trapezoidal block. The nail-shaped lever passes through the rotating shaft sleeve 26. A spring 25 is fixed between the trapezoidal block of the pawl lever 24 and the rotating shaft sleeve 26. The spring 25 is sleeved on the nail-shaped lever. The pawl lever 24 is elastically connected to the rotating shaft sleeve 26 through the spring 25, so that the pawl lever 24 always elastically abuts against the tooth surface of the ratchet 21.

[0024] The working principle is as follows: When the steel strand 17 is tensioned, it drives the pull wheel 16 to rotate clockwise, and the ratchet 21 rotates synchronously. The pawl bar 24 is engaged in the tooth groove of the ratchet 21 under the action of the spring 25, preventing it from rotating counterclockwise and realizing the one-way locking of the steel strand 17 to prevent loosening. If it is necessary to loosen, the nail-shaped bar of the pawl bar 24 is rotated in the opposite direction to make the trapezoidal block flip, so that the locking direction of the ratchet 21 is reversed, or the nail-shaped bar is pulled directly to compress the spring 25 and make the pawl disengage from the ratchet 21.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
