Description

Technical Field

[0001] This utility model relates to the technical field of conductor traction, and in particular to a conductor traction device. Background Technology

[0002] In the construction of high-voltage overhead transmission lines, the stringing process is one of the most critical steps. With the expansion of the power grid and the growth of electricity demand, the efficient and safe erection of conductors has become increasingly important. Currently, conductor pulling is mainly done manually, requiring multiple workers and is quite time-consuming and labor-intensive, increasing costs. Conductor pulling devices are specifically designed to assist in conductor erection, improving efficiency. However, existing conductor pulling devices require multiple operators and limit devices to secure the conductor when pulling stops, lacking self-locking capabilities to prevent the conductor from pulling back due to gravity. This makes the conductor pulling process cumbersome. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides a conductor traction device, which solves the technical problem that conductor erection requires multiple people to work together, and achieves the purpose of improving erection safety and efficiency.

[0004] To solve the above technical problems, the present invention provides the following technical solution: a wire traction device, including a push seat as a support base, a lifting component for supporting and vertically lifting the operator is installed at the top of the push seat, and a wire transmission self-locking component for erecting the wire is installed at the top of the lifting component.

[0005] The wire transmission self-locking assembly includes a stabilizing frame fixedly connected to both sides of the top of the pusher seat. A transmission box is slidably connected between the two stabilizing frames. A transmission motor is mounted on one side of the transmission box via a base. A transmission worm gear is rotatably connected to the lower part of the transmission box. A driven gear meshing with the transmission worm gear is rotatably connected to the bottom of the transmission box. A first wire reel is rotatably connected to the transmission box above the driven gear via a partition. A second wire reel is rotatably connected to the transmission box above the first wire reel via a partition. The ends of the conductive wires on the first and second wire reels are fixedly connected to wire merging boxes. A merging box limit bolt is spirally connected to one side of the wire merging box.

[0006] Preferably, the lifting assembly includes folding grooves at both ends of the inner side of the push seat, a folding slide rod slidably connected to the inner side of the folding groove, one bottom end of the lifting folding frame rotatably connected to the inner wall of the push seat, the other bottom end of the lifting folding frame rotatably connected to the adjacent folding slide rod, a parallel rod rotatably connected between the lifting folding frame and the folding slide rod, a lifting cylinder mounted on the inner side of the push seat via a base, the extension end of the lifting cylinder rotatably connected to the parallel rod, and a lifting top plate rotatably connected to the top of the lifting folding frame.

[0007] Preferably, the transmission motor drive end is connected to one end of the transmission worm, and the wire ends on the first and second wire reels both extend through to the outside of the transmission box.

[0008] Preferably, the top end of the push seat is in contact with the bottom end of the lifting top plate, and the length of the lifting folding frame is less than the opening length of the inner side of the push seat.

[0009] Preferably, guardrails are installed around the top of the lifting top plate, and universal wheels are rotatably connected to the four corners of the bottom of the push seat.

[0011] By employing the above technical solution, this utility model provides a wire traction device, which has at least the following beneficial effects:

[0012] 1. Due to the setting of the wire transmission self-locking component, this utility model can drive the wires on the second wire disk to be output synchronously by rotating the first wire disk. By driving the transmission worm gear, it can self-lock when the transmission stops, thereby avoiding the wire from falling due to excessive transmission length and weight, and improving the efficiency of wire erection and traction.

[0013] 2. Due to the lifting component, the height of the self-locking component for wire transmission can be adjusted according to the site conditions, thus making the equipment more widely applicable. Furthermore, it can also make secondary adjustments to the wires that have problems during the wire pulling process, without requiring operators to climb, thereby reducing safety hazards for operators.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Existing conductor traction devices require multiple operators and limit devices to secure the conductor once traction has stopped. They lack self-locking capabilities to prevent the conductor from pulling back due to gravity, making the conductor traction process cumbersome. Please refer to [reference needed]. Figures 1-6This embodiment provides a conductor traction device that solves the technical problem of requiring multiple people to work together to erect conductors. The device includes a push base 1 as a support foundation, a lifting assembly 2 for supporting and vertically raising / lowering the operator, and a conductor transmission self-locking assembly 3 for erecting the conductor. The two devices are placed opposite each other, and the conductor is pulled and transmitted using the conductor transmission self-locking assemblies 3 on both devices. Once both ends of the conductor reach a fixed point, the lifting assembly 2 raises the pulled conductor to a designated height.

[0028] In the traditional process of erecting conductors, most of the work is still done manually. This method not only increases safety hazards, but also increases production costs due to excessive personnel input, and slows down the erection efficiency. In order to solve these problems, a conductor transmission self-locking component 3 is proposed. The wire transmission self-locking assembly 3 includes a stabilizing frame 31 fixedly connected to both sides of the top of the pusher 1. A transmission box 32 is slidably connected between the two stabilizing frames 31. A transmission motor 33 is mounted on one side of the transmission box 32 via a base. A transmission worm 34 is rotatably connected to the lower part of the transmission box 32. A driven gear 35 meshing with the transmission worm 34 is rotatably connected to the bottom of the transmission box 32. Power is transmitted through the transmission motor 33 and through the meshing transmission worm 34 and driven gear 35. The transmission worm 34 can also achieve self-locking, thereby preventing the wire from gradually sagging due to the increase in weight during the wire traction process. A first wire disc 36 is rotatably connected to the inside of the transmission box 32 above the driven gear 35 via a partition. A second wire disc 37 is rotatably connected to the inside of the transmission box 32 above the first wire disc 36 via a partition. The transmission end of the transmission motor 33 is connected to one end of the transmission worm 34. The wire ends on the first wire reel 36 and the second wire reel 37 are connected and extend through to the outside of the transmission box 32. The transmission end of the transmission motor 33 is connected to one end of the transmission worm gear 34. The power output by the transmission motor 33 drives the first wire reel 36 and the second wire reel 37 to rotate, thereby realizing the traction transmission of the wire. The wire ends on the first wire reel 36 and the second wire reel 37 extend through to the outside of the transmission box 32. The wire ends on the first wire reel 36 and the second wire reel 37 are fixedly connected to the wire merging box 38. The wire merging box 38 is used to merge with the wire. A merging box limit bolt 39 is screwed on one side of the wire merging box 38. The merging box limit bolt 39 fixes the wire inside the wire merging box 38, thereby ensuring that the transmission wire can run synchronously with the wire during the transmission process. Then, the transmission motor 33 is started to drive the wire merging box 38 to pull the erected wire to straighten it.

[0029] Example 2

[0030] Based on Example 1, which solved the technical problem that conductor erection required multiple people to work together, Example 1 still had the problem of requiring operators to lift the conductor to a high position. Combined with... Figures 1-6 As shown, the specific implementation process is as follows: After the conductor traction is completed, the operator also needs to erect the traction conductor. The traditional erection process is carried out by manual climbing, which is not only inefficient but also increases the safety hazards for the operator. In order to solve this problem, the lifting component 2 is proposed. The lifting assembly 2 includes folding grooves 21 at both ends of the inner side of the push seat 1. Folding rods 22 are slidably connected to the inner side of the folding grooves 21. One bottom end of the lifting folding frame 23 is rotatably connected to the inner wall of the push seat 1, and the other bottom end of the lifting folding frame 23 is rotatably connected to the adjacent folding rods 22. A parallel rod 24 is rotatably connected between the lifting folding frames 23 rotatably connected to the folding rods 22. A lifting cylinder 25 is installed on one end of the inner side of the push seat 1 through a base. The extension end of the lifting cylinder 25 is rotatably connected to the parallel rod 24. A lifting top plate 26 is rotatably connected to the top of the lifting folding frame 23. The lifting cylinder 25 pushes the parallel rod 24 to drive one end of the lifting folding frame 23 to slide inside the folding grooves 21 through the folding rods 22, thereby reducing the distance between the lifting folding frames 23 and raising the lifting folding frame 23, thereby raising the lifting top plate 26.

[0031] The top of the push seat 1 is attached to the bottom of the lifting top plate 26. The length of the lifting folding frame 23 is less than the opening length inside the push seat 1 in order to ensure that the lifting folding frame 23 in the retracted state can be completely retracted inside the push seat 1.

[0032] The top of the lifting plate 26 is equipped with guardrails 4 around its top, which protect the safety of operators at high positions. The bottom of the pusher seat 1 is rotatably connected to the four corners of the bottom, and the casters 5 facilitate the transfer of the equipment. The casters 5 are fixedly connected to the outside of the connecting shaft of the pusher seat 1, and the outside of the casters 5 is spirally connected to the offset limiter 7. The offset limiter 7 can lock the casters 5, thereby fixing the position of the equipment. The pusher seat 1 is fixedly connected to one side of the top. The merging box limit bolt 39 and the offset limiter 7 are both bolt limiters. The end of the offset limiter 7 passes through the caster cover 6 and fits against the outer surface of the casters 5.
