Description

Technical Field

[0001] This utility model relates to the technical field of power distribution network construction tools, specifically to a power distribution network guy wire tool. Background Technology

[0002] In power distribution network construction, the winding and management of power lines is a crucial step. During the construction of power distribution lines, long power lines require wire pulling tools for collection and restraint. However, existing wire pulling tools lack restraint mechanisms on the free end of the power line after winding, leaving it in a swinging state. This can lead to the wound power line loosening and scattering when the wire pulling tool is moved.

[0003] Utility model patent application number 202321786957.4 discloses a power distribution network cable pulling tool, including a cable pulling frame and a tripod structure. The cable pulling frame has two corresponding mounting holes inside, with a rotating shaft movably mounted between them. A turntable is sleeved on the outer left side of the rotating shaft, and a winding structure is sleeved on the inner part of the rotating shaft. Mounting grooves are provided on the top walls of both sides of the cable pulling frame. This invention incorporates a cable-clamping ring for securing the cable. After winding, the free end of the cable is clamped into the clamping ring, preventing it from swinging and reducing the likelihood of the cable loosening during movement after winding. While this patent solves the problem of loose cables, the process of inserting the cable end into the clamping ring after operation is cumbersome and inconvenient. Furthermore, the fixed diameter of the clamping ring makes it unsuitable for cables of different diameters, resulting in low practicality. Utility Model Content

[0027] like Figures 1-4 As shown, the power distribution network cable pulling tool disclosed in this embodiment includes a support part 1, a cable winding and unwinding assembly 2, and a tensioning assembly 3. The cable winding and unwinding assembly 2 is disposed on the support part 1 and is used for winding and unwinding cables. The tensioning assembly 3 is disposed on the support part 1 and is located above the cable winding and unwinding assembly 2. The cable passes through the cable threading area of ​​the tensioning assembly 3. When winding and unwinding the cable, the tensioning assembly 3 loosens the cable. After winding and unwinding is completed, the tensioning assembly 3 tightens the cable.

[0028] In practical use, the cable is wound onto the take-up and unwind assembly 2. The free end (wire head) of the cable passes through the threading area of ​​the tensioning assembly 3, and the tensioning assembly 3 locks the wire head in place. This restricts the free swinging of the wire head, preventing the cable from becoming loose after winding. Furthermore, the threading area of ​​the tensioning assembly 3 has a certain degree of freedom, allowing it to adapt to cables of different diameters, thus increasing its practicality. When taking the cable out or in, the cable passes through the threading area. After the take-up and unwinding steps are completed, the wire head can be directly locked using the tensioning assembly 3, eliminating the need for additional threading operations. This simplifies operation and further improves work efficiency.

[0029] Specifically, in this embodiment, the support part 1 includes a base plate 11 and a support frame 12 disposed on the top of the base plate 11. The cable reeling / unloading assembly 2 and the tensioning assembly 3 are both disposed on the support frame 12. Furthermore, the base plate 11 is made of rectangular stainless steel plate, which makes it more stable during use. The support frame 12 consists of two symmetrical vertical plates mounted on the base plate 11, and the cable reeling / unloading assembly 2 and the tensioning assembly 3 are disposed on the vertical plates at different heights. To facilitate the movement of the device, casters 13 are also provided at the bottom of the base plate 11. The casters 13 are equipped with brake pads to facilitate fixing the device after it is moved to a designated position.

[0030] The take-up and unwind assembly 2 includes a take-up roller 21 and a first drive unit 22. The take-up roller 21 is rotatably connected to the support unit 1, and the first drive unit 22 is drively connected to the take-up roller 21. In this embodiment, the first drive unit 22 can be a combination of a motor and a reducer, used to drive the take-up roller 21 to rotate for take-up and unwinding. The take-up roller 21 is rotatably disposed between two vertical plates, and the first drive unit 22 is disposed on the outside of either vertical plate; the two are connected by a shaft drive.

[0031] Please refer to Figure 3 and Figure 4The tensioning assembly 3 includes a connecting part 31, a mounting part 32, a first clamping member 33, a second clamping member 34, and a tensioning mechanism 35. The connecting part 31 is disposed on the support part 1, and the mounting part 32 is disposed at the bottom of the connecting part 31. One end of the first clamping member 33 and one end of the second clamping member 34 are respectively rotatably connected to the two ends of the mounting part 32. The other ends of the first clamping member 33 and the second clamping member 34 cross each other. The first clamping member 33, the second clamping member 34 and the mounting part 32 form a wire threading area. The tensioning mechanism 35 is used to adjust the size of the wire threading area to clamp or loosen the cable.

[0032] Specifically, the inner surfaces of the mounting part 32, the first clamping member 33, and the second clamping member 34 are all arc-shaped plates, matching the outer wall of the cable to reduce damage to the cable after clamping. Furthermore, rubber pads are provided on the inner surfaces of the mounting part 32, the first clamping member 33, and the second clamping member 34 to convert hard friction into soft friction, further protecting the cable. The first clamping member 33 consists of two symmetrically arranged first arc-shaped plates, symmetrically mounted at one end of the mounting part 32 via a pivot pin. The second clamping member 34 is a second arc-shaped plate, rotatably mounted at the other end of the mounting part 32 via a pivot pin. The end of the second arc-shaped plate passes through the gap formed by the two first arc-shaped plates. This arrangement provides greater stability after clamping. When the cable needs to be locked, the degree of intersection between the two plates can be adjusted, thereby reducing the diameter of the cable threading area.

[0033] Further reference Figure 4 The tensioning mechanism 35 includes a first connecting plate 351, a second connecting plate 352, an adjusting part 353, and a locking part 354. The first connecting plate 351 and the second connecting plate 352 are respectively disposed at the other end of the first clamping member 33 and the other end of the second clamping member 34. The adjusting part 353 is disposed between the first connecting plate 351 and the second connecting plate 352 and is used to adjust the relative distance between the first connecting plate 351 and the second connecting plate 352, thereby adjusting the size of the cable threading area. The locking part 354 is disposed on the adjusting part 353 and is used to lock the adjusting part 353. In this embodiment, the tension of the tensioning component 3 is adjusted by adjusting the relative distance between the two connecting plates to achieve the tension of the cable, which is simple to operate.

[0034] Specifically, both the first connecting plate 351 and the second connecting plate 352 are provided with threaded holes. The adjusting part 353 is a double-ended screw, with its two ends threadedly connected to the threaded holes of the first connecting plate 351 and the second connecting plate 352, respectively. The locking part 354 is a locking nut, which is threadedly connected to one end of the double-ended screw. Clockwise rotation moves the two connecting plates closer together, while counterclockwise rotation moves them further apart. When the cable needs to be tightened, the double-ended screw is rotated counterclockwise. Due to the threaded action, the distance between the two connecting plates increases, thus reducing the diameter of the cable threading area and achieving the purpose of tightening the cable. After tightening, the locking nut is rotated to secure the cable and prevent it from loosening. When the cable needs to be loosened, the double-ended screw is rotated clockwise, reducing the distance between the two connecting plates and increasing the diameter of the cable threading area. Similarly, after loosening, the cable is tightened again using the locking nut.

[0035] Preferably, the power distribution network cable pulling tool further includes a horizontal adjustment component 4 disposed on the support part 1. A tensioning component 3 is drively connected to the bottom of the horizontal adjustment component 4. The horizontal adjustment component 4 drives the tensioning component 3 to move horizontally above the take-up and unwinding assembly 2. During take-up and unwinding, the horizontal adjustment component 4 can drive the tensioning component 3 to move horizontally, ensuring smooth and stable take-up and unwinding. When the cable rotates once around the take-up roller 21, the horizontal adjustment component 4 drives the tensioning component 3 forward a distance equal to one cable diameter unit, ensuring the cable is smoothly wound onto the take-up roller 21.

[0036] Preferably, the leveling assembly 4 includes a second drive unit 41 disposed on the support unit 1 and a lead screw drive pair 42. The second drive unit 41 is driveably connected to the lead screw drive pair 42, and the tensioning assembly 3 is driveably connected to the output end of the lead screw drive pair 42. The second drive unit 41 is the same as the first drive unit 22, and can also be a combination of a motor and a reducer. Transmission via the lead screw drive pair 42 results in a more stable and precise transmission process.

[0037] Specifically, the lead screw drive pair 42 includes a drive chamber 421, a lead screw 422, a drive nut 423, and a sliding block 424. The drive chamber 421 is mounted on the support part 1, and a horizontal sliding groove 4211 is provided at the bottom of the drive chamber 421. The lead screw 422 is drively connected to the drive chamber 421, and its setting direction is the same as that of the take-up and unwinding assembly 2. The drive nut 423 is threaded onto the lead screw 422. The sliding block 424 is located at the bottom of the drive nut 423, and the end of the sliding block 424 away from the drive nut 423 passes downward through the sliding groove 4211. The tensioning assembly 3 is located at the bottom of the sliding block 424. In this embodiment, the drive chamber 421 is mounted between two vertical plates, and both ends of the lead screw 422 are rotatably connected to the two vertical plates. Bearings can be configured at the connection points. The second drive part 41 is mounted on either vertical plate and is connected to the lead screw 422 via shaft drive. When the transmission screw 422 rotates, the sliding groove 4211 and the transmission nut 423 cause the tensioning assembly 3 to move horizontally in a straight line. Furthermore, two guide rods 425 are provided inside the transmission chamber 421. These two guide rods 425 are symmetrically arranged on both sides of the transmission screw 422, with their ends connected to two vertical plates respectively. Both guide rods 425 pass through the transmission nut 423, further guiding the linear movement of the tensioning assembly 3 and making its horizontal movement more stable. In addition, the horizontal adjustment assembly 4 also includes two limit sensors 43 located at both ends inside the transmission chamber 421. Two limit sensors 43 sense the distance between the transmission nut 423 and either end of the take-up roller 21. When the distance between the transmission nut 423 and either end of the take-up roller 21 is reached, the cable has wrapped around the take-up roller 21 once. The limit sensors 43 then send a signal, causing the motor of the second drive unit 41 to reverse, which in turn causes the transmission screw 422 to drive the tensioning assembly 2 in a reverse linear motion, allowing the cable to begin wrapping a second layer, ensuring a neater cable take-up on the take-up roller 21. Specifically, the connecting part 31 is a connecting rod with a thread at one end, and the bottom of the sliding block 424 has a threaded hole, with the threaded end of the connecting rod threaded into the threaded hole.

[0038] The power distribution network cable pulling tool in this embodiment can adjust the size of the cable threading area by setting the tensioning component 2, which can accommodate cables of different diameters and improve its practicality. In addition, the cable is always in the cable threading area when winding and unwinding the cable. After winding and unwinding the cable, the cable end can be locked by simply tightening the tensioning component 2, making the operation simpler.
