Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically a wiring auxiliary frame for power construction. Background Technology

[0002] During the laying of electrical wires, various pulling, clamping, and positioning operations are required. At the wire connection points, manual operation is usually required to connect two wire segments. However, during the connection process, the ends of the two wire segments need to be brought close together. But because the wires are often in a coiled or tightened state during manufacturing and laying, the ends of the wires often naturally retract backward during the connection process, causing poor contact between the wire cores or posing a danger to the electrician. Furthermore, it cannot be used with wires of different diameters, resulting in poor versatility.

[0003] Chinese patent discloses an auxiliary frame for power construction wiring (authorization announcement number CN211428786U). This patented technology uses a screw to adjust the distance between spool one and spool two to clamp wires of different diameters, which can avoid the danger caused by the natural shrinkage of the wires to the wiring, and at the same time improve the versatility.

[0004] However, it has certain drawbacks: when using it, the operator needs to adjust the position of the two cables separately, that is, pull one cable to a position close to the middle, and then free up their hand to pull the other cable to a position close to the middle. This not only increases the complexity of the operation, but also causes the first cable to retract due to its own elasticity. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary frame for power construction wiring to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A wiring auxiliary frame for power construction includes a base, on both the front and rear sides of the upper surface of the base, a sliding groove is provided inside the sliding groove, and a clamping mechanism is provided at the upper end of the sliding groove.

[0008] An L-shaped plate is fixed to the right edge of the upper surface of the base. A rotating rod is rotatably connected to the left end of the L-shaped plate. A gear is fixed to the lower end of the rotating rod. Racks are meshed on both sides of the gear. A positioning mechanism is provided on the upper surface of the L-shaped plate and the outside of the rotating rod.

[0009] As a further embodiment of this utility model: the clamping mechanism includes a support frame, a support rod is threadedly connected to the upper surface of the support frame, and a support block is rotatably connected to the lower end of the support rod.

[0010] As a further embodiment of this utility model: the positioning mechanism includes a ratchet and a pawl that fits into the ratchet. A positioning rod is rotatably connected to the right end of the pawl, and a spring is fixedly connected to the front surface of the pawl. A positioning block is fixedly connected to the front end of the spring.

[0011] As a further embodiment of this utility model: the front end of the rack on the left is fixed to the front slider, and the rear end of the rack on the right is fixed to the rear slider.

[0012] As a further embodiment of this utility model: the lower end of the support frame is fixed to the upper surface of the slider, and the end of the support block is slidably connected to the inner left and right surfaces of the support frame.

[0013] As a further embodiment of this utility model: the ratchet is fixed to the outside of the rotating rod, and the ratchet is located above the L-shaped plate; the lower ends of the positioning rod and the positioning block are both fixed to the upper surface of the L-shaped plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The ends of the two cables are placed in the support frames of the two clamping mechanisms respectively. Rotating the support rod will cause the support block to descend and clamp the cables. Pushing the clamping mechanism towards the middle will bring the two cables closer together, thus facilitating wiring.

[0016] 2. When one clamping mechanism is pushed towards the center, the other clamping mechanism will move towards the center simultaneously under the action of the rack and pinion. It is not necessary to pull one clamping mechanism to bring it close to the center before pulling the other, thus simplifying the operation. The pawl engages with the ratchet, preventing the lever from rotating counterclockwise, thus preventing the two clamping mechanisms that are close together from separating due to accidental collisions or other factors.

[0021] Please see Figure 1 and Figure 2 In this embodiment of the utility model, a power construction wiring auxiliary frame includes a base 1. The upper surface of the base 1 is provided with sliding grooves 2 on both the front and rear sides. A slider 3 is slidably connected inside the sliding grooves 2. A clamping mechanism 4 is provided at the upper end of the slider 3. The clamping mechanism 4 includes a support frame 5. The lower end of the support frame 5 is fixed to the upper surface of the slider 3. A support rod 6 is threaded through the upper surface of the support frame 5. A support block 7 is rotatably connected to the lower end of the support rod 6. The end of the support block 7 is slidably connected to the inner left and right sides of the support frame 5.

[0022] Rotating the support rod 6 can drive the support block 7 to rise and fall, which is used to clamp and fix the cable; the two clamping mechanisms 4 are used to clamp the two cables. The slider 3 brings the two clamping mechanisms 4 together, so that the ends of the two cables are close together, which makes it easier to connect the two cables.

[0023] The support frame 5 consists of an upper frame and a lower frame, which are fixed together by locking blocks and bolts. After the cable is wired, the upper frame can be removed to facilitate the removal of the cable from the support frame 5.

[0024] The lower inner surface of the support frame 5 and the lower surface of the support block 7 are both angular surfaces, which facilitates clamping the cylindrical structure of the cable and is suitable for cables of different diameters.

[0025] exist Figure 1 In the middle: An L-shaped plate 8 is fixedly connected to the right edge of the upper surface of the base 1. A rotating rod 9 is rotatably connected to the left end of the L-shaped plate 8. A gear 10 is fixedly connected to the lower end of the rotating rod 9. A rack 11 is meshed on both the left and right sides of the gear 10. The front end of the left rack 11 is fixedly connected to the front slider 3, and the rear end of the right rack 11 is fixedly connected to the rear slider 3.

[0026] Pushing one clamping mechanism 4 drives a rack 11 to move. Under the action of the gear 10 and another rack 11, the other clamping mechanism 4 will move synchronously. This allows the two clamping mechanisms 4 to move closer to each other at the same time. It eliminates the need to pull one clamping mechanism 4 to bring it closer to the middle position before pulling the other one, thus simplifying the operation.

[0027] exist Figure 1 and Figure 3In the middle: The upper surface of the L-shaped plate 8 and the outside of the rotating rod 9 are jointly provided with a positioning mechanism 12. The positioning mechanism 12 includes a ratchet 13 and a pawl 14 that fits into the ratchet 13. The ratchet 13 is fixed to the outside of the rotating rod 9 and is located above the L-shaped plate 8. The right end of the pawl 14 is rotatably connected to a positioning rod 15, and the front surface of the pawl 14 is fixed to a spring 16. The front end of the spring 16 is fixed to a positioning block 17. The lower ends of the positioning rod 15 and the positioning block 17 are both fixed to the upper surface of the L-shaped plate 8.

[0028] As the two racks 11 drive the two clamping mechanisms 4 to approach each other, the gear 10 drives the rotating rod 9 to rotate clockwise, and the ratchet 13 also rotates clockwise. The pawl 14 engages with the ratchet 13, preventing the rotating rod 9 from rotating counterclockwise. This keeps the two clamping mechanisms 4 very close together, preventing them from moving away from each other due to accidental contact or the elasticity of the cable.

[0029] After pulling the pawl 14 away from the ratchet, the lever 9 can rotate counterclockwise.

[0030] The working principle of this utility model is as follows: First, expose a section of the cable end and place it into the support frame 5. Then, rotate the support rod 6 to make it lower the support block 7 until the cable is fixed. Fix the other cable in the same way. Next, push one clamping mechanism 4 towards the middle. Under the action of the rack 11 and gear 10, the other clamping mechanism 4 also moves towards the middle until the cables on the two clamping mechanisms 4 are close together. At this time, the staff can perform the wiring process on the cable.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
