Description

Technical Field

[0001] The present invention relates to the technical field of live working, and more particularly, to a wiring auxiliary device for live working. Background Art

[0002] Live working refers to tasks such as maintenance, inspection, or installation carried out while electrical equipment remains in an operating state. Such operations require operators to not only possess excellent professional skills but also strictly follow safety regulations to effectively avoid safety accidents such as electric shock. Especially in the wiring process of live working, the technical requirements are particularly strict. Currently, the commonly used method is for professional electricians to climb to a designated position on the utility pole, then remove the insulation layer at the intersection of the main line and the branch line, make them closely contact, and then wind the wire of the branch line around the main line. Finally, insulating materials (such as insulating tape) are used for further fixation. However, this method has some obvious deficiencies in practical applications:

[0003] 1. When the main line and the branch line need to be joined, the electrician needs to manually hold the main line steady to accurately push the branch line towards the main line to achieve their initial contact. This process requires the electrician's hand to continuously touch the live main line, which increases the risk of electric shock. Especially when the operation time is extended, due to the operation, the hand has to touch the main line or the branch line in the live environment from time to time, increasing the operation risk accordingly.

[0004] 2. When performing the wire winding step of the main line and the branch line, since the main line is usually located at a relatively fixed point, this also causes the shape of the main line to be relatively fixed, which brings additional challenges to the subsequent joining and winding work of the branch line. The operator often needs to spend more time and effort to adjust the position of the main line to ensure that the two can be smoothly connected. This not only has a low work efficiency but may also affect the final wiring quality due to improper operation. Summary of the Invention

[0005] In order to overcome the above-mentioned drawbacks existing in the prior art, the present invention provides a wiring auxiliary device for live working that can reduce the hand contact operation time and facilitate the adjustment of the fitting shape of the main line, aiming to improve the safety and efficiency of live wiring operations.

[0011] The shaping section is located on both sides of the auxiliary frame and is used to fix and assist in straightening the main line.

[0012] Preferably, the fastening part includes two sets of guide rods respectively disposed on two buckles. The guide rods in the same set are arranged symmetrically from left to right, and a locking frame for fixing the branch line is also slidably disposed between the two guide rods. An elastic element is disposed between the locking frame and the guide rod on the same side. A contact frame is slidably disposed at the front end of the buckle. A pull rope is disposed between the bottom end of the contact frame and the locking frame on the same side. An inclined frame that contacts and cooperates with the contact frame on the same side is also symmetrically disposed at the bottom of the push-pull frame.

[0013] Preferably, the shaping part includes sleeves connected to both sides of the auxiliary frame. The sleeves have a notch on the side facing the push-pull frame to facilitate the entry of the main line. The sleeves are provided with pull rings that slide along the surface and four clamping plates that slide through at intervals along the circumference. Each clamping plate is provided with an inclined surface, and the pull rings are in contact with the inclined surfaces of the clamping plates on the same side to push the clamping plates to move for clamping and straightening the main line.

[0014] Preferably, a positioning component is provided on the push-pull frame. The positioning component is used to fix the position between the push-pull frame and the auxiliary frame. The positioning component includes a toothed rack symmetrically arranged on the push-pull frame. The rear end of the toothed rack passes through the limiting ring on the same side and the two slide together. A limiting rod is provided on each side of the auxiliary frame and slides through it, engaging with the toothed rack on the same side. An elastic element is also provided between the limiting rod and the auxiliary frame.

[0015] Preferably, the auxiliary frame is provided with a winding part for assisting film winding. The winding part includes an assembly frame respectively provided on both sides of the auxiliary frame. An arc-shaped guide rail one and an arc-shaped guide rail two are connected vertically at intervals on the assembly frame. A movable plate is slidably provided between the arc-shaped guide rail one and the arc-shaped guide rail two on the same side. An insert rod is inserted between the two movable plates. An installation cylinder for assembling film is slidably provided on the insert rod, and an end cap is locked at the end of the installation cylinder.

[0016] Preferably, the insertion rod has symmetrically arranged slots, and the inner side of the mounting cylinder and the end cap is provided with two retaining strips that are consistent with the slot layout, so as to restrict the rotation of the mounting cylinder and the end cap.

[0017] Preferably, the winding part further includes a locking rod rotatably mounted on a movable plate on one side, a torsion spring is provided between the locking rod and the corresponding movable plate, and the ends of the locking rod and the insertion rod are engaged.

[0019] The beneficial effects that this invention can achieve by overcoming the shortcomings of the prior art include:

[0020] 1. This invention effectively reduces manual intervention during the approach of branch lines to main lines through the sliding mechanism between the auxiliary frame and the push-pull frame, significantly reducing the risk of operators directly contacting live parts. In addition, the cleverly designed fastening and shaping parts ensure the stability of the relative position between branch lines and main lines, making them easier to connect, greatly simplifying the wiring process, and improving the safety and efficiency of live wiring operations.

[0021] 2. This invention introduces a winding section design. By using the circumferential sliding function of the moving plate, the film roll can be wound around the branch line and the main line. This not only provides additional support for the splicing operation, ensuring the quality and speed of tape winding, but also greatly improves the usability of the entire splicing process, making the operation more convenient and efficient.

[0022] 3. The present invention designs a matching mechanism between the rack and pinion and the limiting rod to ensure precise control of the relative position between the push-pull frame and the auxiliary frame. This not only effectively limits the displacement of the push-pull frame after completing a specific action, but also further enhances the stability of the connection between the branch line and the main line, ensuring the accuracy of subsequent operations and providing an important guarantee for the safety of the entire wiring process.

Therefore, they should not be construed as limitations on this invention.

[0033] Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The technical solutions of the present invention will now be clearly and completely described in conjunction with the accompanying drawings. It should be understood that the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0034] Example: A wiring auxiliary device for live-line working, such as Figures 1-5 As shown, it includes:

[0035] Auxiliary frame 1 serves as the basic framework for the entire device;

[0036] There are two limiting rings 2, which are respectively connected to the left and right ends of the front side of the auxiliary frame 1. The front side of the limiting ring 2 has a notch so that the main line can be embedded between the two limiting rings 2 to help fix the position of the main line.

[0037] The push-pull frame 3 is slidably installed between two limiting rings 2, and can slide back and forth between the limiting rings 2. A buckle 31 is provided at each of the front ends of the push-pull frame 3, with the opening of the buckle 31 facing backward, to assist in supporting the position of the branch line. By moving the push-pull frame 3 back and forth, the branch line is brought closer to the main line, and the two are brought into contact, which reduces the time of direct contact between personnel and wires, further reduces the risk of live work, and improves the overall safety of the operation, making the wiring operation more convenient and faster.

[0038] The fastening part 4 is respectively provided on the two fastening rings 31 to assist in fixing the position of the branch line and ensure that the branch line can be firmly fixed.

[0039] The shaping parts 5 are respectively set on the left and right sides of the auxiliary frame 1, and are used to fix and assist in straightening the main line.

[0040] like Figure 1 , Figure 3 and Figure 4 As shown, the fastening part 4 includes two sets of guide rods 41 respectively disposed on two buckles 31. The guide rods 41 in the same set are arranged symmetrically from left to right, and a locking bracket 42 for fixing the branch line is also slidably disposed between the two guide rods 41. The guide rods 41 are arc-shaped with their openings facing backward, so that the guide rods 41 can conform to the shape contour of the buckle 31, providing a sliding path for the movement of the locking bracket 42. As the locking bracket 42 slides along the trajectory of the guide rods 41, the rear end of the buckle 31 is extended, thereby firmly gripping and fixing the branch line embedded between the buckles 31. An elastic element 43 is provided between the locking bracket 42 and the guide rods 41 on the same side. In this embodiment, The elastic element 43 is a spring, which can provide elastic support for the reset movement of the positioning frame 42. The front side of the buckle 31 is slidably provided with a contact frame 44, which slides in the up and down direction. A pull rope 45 is provided between the bottom end of the contact frame 44 and the positioning frame 42 on the same side. At the bottom of the push-pull frame 3, there are also symmetrically arranged inclined frames 46 that contact and cooperate with the contact frame 44 on the same side. The inclined slope of the inclined frame 46 is inclined downward from front to back. By using the contact between the contact frame 44 and the inclined frame 46, the positioning frame 42 is pulled to the front by the pull rope 45, so as to release the rear fixation of the branch line, so that the connection part of the branch line can be attached to the main line.

[0041] like Figure 1 , Figure 4 and Figure 5As shown, the shaping part 5 includes sleeves 51 connected to the left and right sides of the auxiliary frame 1. Each sleeve 51 has a notch on the side facing the push-pull frame 3 to facilitate the entry of the main cable. Utilizing a symmetrical layout, the main cable entering between the two sleeves 51 receives support from two points on the left and right, thus limiting the position of the main cable and straightening its connection point, creating a relatively horizontal position with the auxiliary frame 1. This allows for a more comprehensive and complete contact area between the subsequent branch cable and the main cable. A pull ring 53 is provided on the sleeve 51, which slides along its surface to facilitate... Four clamping plates 52 are slidably arranged along the circumference. Each clamping plate 52 is provided with an inclined surface 521. The pull ring 53 is in contact with the inclined surface 521 of the clamping plate 52 on the same side. The sides of the clamping plates 52 on the left and right sides of the inclined surface 521 are flat with one higher and one lower plane. This allows the pull ring 53 to restrict the position of the clamping plate 52 by the planes on both sides after it moves to the end of the inclined surface 521. The lower plane is suitable for stabilizing the initial position of the clamping plate 52, while the higher plane is used to hold the clamping plate 52 in place after it has moved, thereby clamping and fixing the position of the main line after it has been straightened.

[0042] like Figure 2 As shown, a positioning component is provided on the push-pull frame 3. The positioning component is used to fix the position between the push-pull frame 3 and the auxiliary frame 1. The positioning component includes a toothed rack 32 symmetrically arranged on the side of the push-pull frame 3. The rear end of the toothed rack 32 passes through the limiting ring 2 on the same side and the two slide together. On the left and right sides of the top of the auxiliary frame 1, a limiting rod 33 is respectively provided and slides through and engages with the toothed rack 32 on the same side. The bottom end of the limiting rod 33 is a wedge-shaped block, which can use the inclined surface on the front side to form a push-in engagement with the toothed rack 32, and then the plane on the rear side can abut against the toothed rack 32 to form a locking engagement to fix the position of the push-pull frame 3 after it moves. An elastic element 34 is also provided between the limiting rod 33 and the auxiliary frame 1. In this embodiment, the elastic element 34 is a spring, which provides elastic support for the movement of the limiting rod 33.

[0043] like Figure 1 , Figures 6-8As shown, the auxiliary frame 1 is provided with a winding section 6 for assisting in film winding. The winding section 6 includes assembly frames 61 respectively disposed on the left and right sides of the auxiliary frame 1. Arc-shaped guide rail 1 62 and arc-shaped guide rail 2 63 are connected vertically at intervals on the assembly frame 61. A gap is left between the front ends of arc-shaped guide rail 1 62 and arc-shaped guide rail 2 63 on the same side to provide space for the movement of the branch line so that the branch line can fit with the main line. A movable plate 64 is slidably disposed between arc-shaped guide rail 1 62 and arc-shaped guide rail 2 63 on the same side, so that the movable plate 64... 4. It can slide circumferentially between the corresponding arc-shaped guide rail 1 62 and arc-shaped guide rail 2 63 to form an operation state close to film winding. A plug rod 65 is inserted between the two moving plates 64. A mounting cylinder 66 for assembling film is slidably arranged on the plug rod 65, and an end cap 661 is locked on the left end of the mounting cylinder 66. The plug rod 65 has symmetrically arranged slots. Two retaining strips with the same slot layout are arranged on the inner side of the mounting cylinder 66 and the end cap 661 to restrict the rotation of the mounting cylinder 66 and the end cap 661.

[0044] like Figure 6 As shown, the winding part 6 also includes a locking rod 67 rotatably mounted on a side movable plate 64. A torsion spring is provided between the locking rod 67 and the corresponding movable plate 64, and the locking rod 67 is engaged with the end of the insertion rod 65 to fix the position of the insertion rod 65.

[0045] like Figure 7 As shown, it also includes a chuck 7. The end of the insertion rod 65 is provided with a chuck 7. A locking block 71 that slides through the moving plate 64 on the same side and engages with the chuck 7 is provided. An elastic element 72 is provided between the locking block 71 and the corresponding moving plate 64. In this embodiment, the elastic element 72 is a spring. By utilizing the contact engagement between the chuck 7 and the locking block 71, the rotation of the insertion rod 65 is restricted by resistance, thereby stabilizing the winding shape of the film.

[0046] When wiring is required during live-line work, first pull down the contact frames 44 on both sides, allowing them to slide downwards on the push-pull frame 3. Simultaneously, the pull rope 45, moving with the contact frames 44, pulls the locking frames 42 on both sides, causing them to slide on the guide rod 41. This causes the elastic element 43 to deform, and the locking frame 42 moves along the guide rod 41 to the front of the retaining ring 31, opening the rear notch of the retaining ring 31. The branch line can then be placed between the two retaining rings 31. After releasing the contact frames 44, the elastic element 43 resets, causing the locking frame 42 to return to its original position under the force of the reset force, and then press against the rear of the branch line. The locking frame 42 and the retaining ring 31 work together to secure the branch line in a wrap-around manner, thus completing the support of the branch line. The worker can then climb to the location where wiring is needed. The position of the main line is determined and the position of the limiting ring 2 and the sleeve 51 is calibrated. The main line is then fastened between the limiting ring 2 and the sleeve 51 on both sides. The sleeves 51 on both sides provide support points for the two ends of the main line connection part, so that the connection part of the main line is straightened and is in a relatively horizontal state with the auxiliary frame 1. Then, the pull rings 53 on both sides are pushed towards the inclined surface 521 of the corresponding clamping plate 52, so that the pull rings 53 contact the inclined surface 521, and then squeeze the clamping plate 52 along the trajectory of the inclined surface 521, so that the clamping plate 52 is pushed down into the sleeve 51. Then, each clamping plate 52 is pushed inward and contacts the two ends of the main line of the connection part. When the pull ring 53 moves to the end of the inclined surface 521, it will press against the clamping plate 52, so that the clamping plate 52 squeezes the main line, thereby clamping and fixing the two ends of the main line of the connection part for subsequent connection operations.

[0047] Then, the push-pull frame 3 can be pulled backward to push the connection point of the branch line closer to the main line. During the movement of the push-pull frame 3, the contact frame 44 will move and come into contact with the inclined frame 46 on the same side. It will then be squeezed by the inclined slope of the inclined frame 46 and move accordingly, which will pull the locking frame 42 to slide away from the rear of the branch line, so that the branch line can directly contact the main line. At the same time, as the push-pull frame 3 moves, the locking rack 32 will come into contact with the lower end of the limiting rod 33 and push the limiting rod 33 to move upward accordingly. The elastic element 34 will deform accordingly. After the branch line moves to the end, the push-pull frame will stop. The movement of 3 causes the elastic element 34 to return to its original position, allowing the limiting rod 33 to engage with the toothed rack 32, thus fixing the position of the push-pull bracket 3. Then, the branch wire and the main wire connection can be wound together. Next, rotate the locking rod 67 to disengage it from the end of the insertion rod 65, then push the insertion rod 65 to the right, pulling its left end out of the moving plate 64. Then, remove the end cap 661 and the mounting cylinder 66, pull the end cap 661 from the mounting cylinder 66, put the required film roll onto the mounting cylinder 66, then snap the end cap 661 back into the mounting cylinder 66 and insert both back into the insertion rod 6. 5. Next, insert the rod 65 back into the left movable plate 64, then release the locking rod 67. The torsion spring returns to its original position, locking the locking rod 67 onto the end of the rod 65. Then, the film winding work can begin. The operator holds the rod 65 and pushes it to rotate, thereby causing the movable plates 64 on both sides to slide circumferentially between the first arc-shaped guide rail 62 and the second arc-shaped guide rail 63 to wind the film. During this process, the position of the mounting cylinder 66 can be pushed according to the change in the winding position, so that it slides accordingly on the rod 65. This changes the position of the film for winding. Simultaneously, as the film winds, its circumferential rotation causes the insert rod 65 to rotate, which in turn causes the chuck 7 on the insert rod 65 to rotate, making it contact the locking block 71. This pushes the locking block 71 to move, and the elastic element 72 deforms accordingly. As the insert rod 65 rotates, it experiences friction and resistance from the contact between the chuck 7 and the locking block 71, thus limiting the rotation of the insert rod 65 to a certain extent. This keeps the film in a relatively taut state, maintaining the tape's straightness and improving the final winding effect.
