[0017] like Figure 1-Figure 4 FIG. 1 shows a first embodiment of an auxiliary wire pulling device for low-voltage cable detection operations according to the present invention.

The retractable insulating rod 1 is relative to the clamping head assembly 4 at the other end, and the clamping head assembly 4 includes: a base 41, a first clamp 42 mounted on the base 41 and a second clamp 43 that can reciprocate and retract relative to the base 41, wherein: one end of the pull wire 25 passes through the hollow rod body 11 and is fastened to the second clamp 43; the driving motor 24 sequentially links the motor coupling 23 and the take-up reel 22 to tighten the pull wire 25, and the pull wire 25 links the second clamp 43 to change the position of the second clamp 43 relative to the first clamp 42, so that the cable is fixed by the cooperation of the two.

[0019] In specific implementation, the retractable insulating rod 1 is composed of a plurality of hollow rods 11 that are sleeved together, and the operating distance can reach 0-1.5m. The handle 3 is fixedly mounted on the tail end of the wire take-up assembly 2.

[0020] The wire-taking assembly 2 is connected to the telescopic insulating rod 1 , and the wire-taking drum 22 is connected to the pull wire 25 . In order to facilitate winding, the pull wire 25 can be tightened by the action of the wire-taking drum 22 .

[0021] Preferably, the wire take-up assembly further comprises: a controller 26 installed in the housing 21 , the controller 26 being connected to the drive motor 24 , and the start or shut down of the drive motor 24 being controlled by the controller 26 .

[0022] During operation, a power supply 7 for supplying power to the drive motor 24 is also installed at the bottom of the handle 3. The power supply 7 is connected to the drive motor 24. When the forward start button of the controller 26 is pressed, the power supply 7 supplies power to the drive motor 24, which starts the drive motor 24 and rotates the take-up reel 22 by driving the motor coupling 23.

[0023] The clamping head assembly 4 is arranged at the top end of the telescopic insulating rod 1. The clamping head assembly 4 includes a base 41, a first clamp 42 mounted on the base 41, and a second clamp 43 that can reciprocate and retract relative to the base 41. The first clamp 42 is fixedly mounted on the top end of the telescopic insulating rod 1, and the second clamp 43 is connected to the pull wire 25 passing through the hollow rod body 11. A tension spring seat 5 is arranged between the second clamp 43 and the top end of the telescopic insulating rod 1, wherein: the tension spring seat 5 is assembled on the base 41, and the second clamp 43 is assembled in the tension spring seat 5. The pull wire 25 links the second clamp 43 to press the tension spring seat 5, and the tension spring seat 5 keeps the pull wire 25 in a taut state.

[0024] Preferably, a guide rod 430 is connected to the bottom of the second clamp 43 , and the guide rod 430 is assembled on the tension spring seat 5 to facilitate installation of the tension spring seat 5 .

[0025] Preferably, the top of the first clamp 42 is a bending head 421, which corresponds to the top of the second clamp 43. Soft material is provided at the contact position between the first clamp 42 and the second clamp 43, thereby effectively preventing damage to the wire during the cable clamping process.

[0026] Furthermore, a sliding limiter 431 is provided on the side of the second clamp 43 , and the sliding limiter 431 extends into the guide groove 422 on the side of the first clamp 42 , thereby providing a better guide for the movement of the second clamp 43 .

[0027] It is understandable that the retractable insulating rod 1, the housing 21 of the wire take-up assembly 2 and the handle 3 are made of insulating materials, which meet the requirements for safe use of electricity.

[0028] Furthermore, it also includes: a lighting assembly, which includes a plurality of LED lamp beads 6, and the LED lamp beads 6 are set to multiple and evenly distributed on the top of the base 41. In specific implementation, the lighting assembly also includes a battery to power the LED lamp beads 6, so that it can provide lighting effects when there is no lighting condition on site.

[0029] During the specific implementation of the auxiliary wire pulling device for low-voltage cable inspection in this embodiment, the clamping head assembly 4 is in a normally closed state when not in use. When it is necessary to disassemble or assemble a meter and change the line, first hold the handle 3 tightly, adjust the retractable insulating rod 1 to a suitable operating distance, press the forward start button 7 of the controller 26 to power the drive motor 24, and the drive motor 24 starts, driving the motor coupling 23 to rotate the take-up reel 22. At this time, the tension spring seat 5 is pulled by the pull wire 25 to contract and tighten, and the second clamp 43 is linked to the action. The second clamp 43 is opened a certain distance relative to the first clamp 42, and this distance is sufficient to ensure that it can be inserted between the wires.

[0030] At this time, you only need to clamp the first clamp 42 and the second clamp 43 between the wires. After determining the position, you only need to press the reverse start button of the controller 26. The power supply 7 supplies power to the drive motor 24, and the drive motor 24 starts, driving the motor coupling 23 to rotate the wire reel 22. At this time, by loosening the pull wire 25, the tension spring seat 5 and the second clamp 43 are restored. At this time, the second clamp 43 of the auxiliary wire pulling device used for low-voltage cable detection operations will automatically clamp the wire and can pull the wire out safely.

[0031] It is understood that the soft material at both ends of the first clamp 42 and the second clamp 43 of the auxiliary wire pulling device used for low-voltage cable inspection prevents damage to the wire during clamping. The retractable insulating rod 1, the housing 21 of the wire take-up assembly 2, and the handle 3 are made of insulating materials, meeting safety requirements for electrical use.

[0032] In addition, the auxiliary wire pulling device used for low-voltage cable detection operations is also equipped with a lighting component, which can provide lighting effects when there are no lighting conditions on site.

[0033] During testing of an auxiliary wire-pulling device for low-voltage cable inspection, the applicant discovered that the use of this specialized tool significantly improved the efficiency and standardization of meter installation and power connection, increasing work efficiency by approximately 50%. The specialized tool's operation is highly standardized, with a single operation taking no more than 12 minutes, significantly improving operational efficiency.

[0034] In addition, this special tool can also improve the efficiency and specifications of the current meter replacement and power connection operations, shorten the meter replacement time and reduce fire and electric shock accidents caused by live wires contacting the metal meter box. It has a streamlined structure and is easy to operate.

[0035] The auxiliary wire pulling device for low-voltage cable detection operations of the present invention has the following beneficial effects:

[0036] First, the clamping head assembly includes: a base, a first clamp mounted on the base and a second clamp that can reciprocate and extend relative to the base, wherein: one end of the pull wire passes through the hollow rod body and is tightly connected to the second clamp; the driving motor sequentially links the motor coupling and the take-up reel to tighten the pull wire, and the pull wire links the second clamp to change the position of the second clamp relative to the first clamp, so that the cable is fixed by the mutual cooperation of the two, and the meter can be safely, quickly and efficiently disassembled and assembled under power, which can avoid damage to the cable insulation layer and meet the requirements of safe electricity use.

[0037] Second, it has a simple structure and is easy to operate, which can significantly improve the efficiency and standardization of meter installation and power connection.
