[0047] The first detection part 823 includes a mounting tube 8231; illustratively, as Figure 7 shown.
[0048] The assembly tube 8231 is an open cylindrical structure, and a digital megohmmeter 8232 is provided at one end of the inner wall of the assembly tube 8231 away from the opening, an electric push rod 8233 is fixedly connected to the outer wall of the digital megohmmeter 8232, and the output end of the electric push rod 8233 is transmission-connected to the third motor 8234, the output end of the third motor 8234 is transmission-connected to the linkage plate 8235, and a controller 8236 is embedded and installed on the linkage plate 8235, a first meter pen head 8237 and a second meter pen head 8238 are provided at the bottom end of the linkage plate 8235, and the electric push rod 8233, the third motor 8234, the first meter pen head 8237, the second meter pen head 8238 and the digital megohmmeter 8232 are all electrically connected to the controller 8236.
[0049] Specifically, the output end of the electric push rod 8233 pushes the linkage plate 8235, so that the first meter pen tip 8237 and the second meter pen tip 8238 are in contact with the ground wire and the live wire at the end of the cable body 7, and the detected data is transmitted to the digital megohmmeter 8232. If the test result is greater than 0.5 megohms, the insulation test of the cable body 7 is normal. The third motor 8234 is used to drive the linkage plate 8235 to rotate, so that the positions of the first meter pen tip 8237 and the second meter pen tip 8238 are changed to meet the different positions of the ground wire, the live wire and the neutral wire at the end of the cable body 7, so that the transformed first meter pen tip 8237 and the second meter pen tip 8238 can contact the ground wire and the neutral wire, or the neutral wire and the live wire.
[0050] The first adjustment mechanism 84 includes a dual-axis motor 841; illustratively, Figure 8 shown.

[0052] Furthermore, the fourth motor 844 is a self-locking motor.
[0053] Specifically, the dual-axis motor 841 drives the screw rod 843 to rotate, so that the two groups of driven blocks 842 threadedly connected to the screw rod 843 are close to each other or away from each other. When the two groups of driven blocks 842 are close to each other, the self-locking mechanism of the fourth motor 844 is used to fix the driving wheel 845. The two groups of driving wheels 845 that are close to each other use the raised rollers 846 to clamp the outer wall of the wire rope 6 or the cable body 7, so that the wire rope 6 and the cable body 7 are fixedly clamped at both ends of the test fixture assembly 8.
[0054] When the two groups of driven blocks 842 are away from each other, the fourth motor 844 is used to cancel the self-locking mechanism to make the driving wheel 845 in a drivable state, and then the fourth motor 844 is used to drive the driving wheel 845 to rotate, so that the raised roller 846 drives the outer wall of the steel wire rope 6 or the cable body 7, so that the ends of the steel wire rope 6 and the cable body 7 are close to each other and penetrate the two ends of the clamp cylinder 8261;

[0060] The working principle of the cable laying device of the insulation test winch proposed in the embodiment of the present invention is as follows:
[0061] First, discharge the voltage of the cable through the discharge rod, take the lines and equipment that need to be repaired out of operation, reliably ground the tail end of the discharge rod, firmly contact the front end of the discharge rod with the conductive part of the cable head, and discharge phase by phase until there is no discharge spark, then use the short-circuit line to discharge between phases. For equipment or cables below 10KV, the discharge time for each phase shall not be less than 1 minute;
[0062] The second guide hole 834 is sleeved on the outside of the cable body 7, and the first guide hole 814 is sleeved on the outside of the steel wire rope 6. The double-axis motor 841 is used to drive the screw rod 843 to rotate, so that the two groups of driven blocks 842 threadedly connected to the screw rod 843 are close to each other or away from each other. When the two groups of driven blocks 842 are close to each other, the self-locking mechanism of the fourth motor 844 is used to keep the driving wheel 845 in a fixed state. The two groups of driving wheels 845 that are close to each other use the raised roller 846 to clamp the outer wall of the steel wire rope 6 or the cable body 7, so that the steel wire rope 6 and the cable body 7 are fixedly clamped at both ends of the test fixture assembly 8.
[0063] The wire rope 6 is driven by the hoist body 10, so that the cable body 7 is wound around the first guide pulley 4 and the second guide pulley 5 in sequence, so that the wire rope 6, the cable body 7 and the test fixture assembly 8 are arranged vertically;
[0064] The linkage plate 8235 is pushed by the output end of the electric push rod 8233, so that the first meter pen tip 8237 and the second meter pen tip 8238 are in contact with the ground wire and the live wire at the end of the cable body 7, and the detected data is transmitted to the digital megohmmeter 8232. If the detection result is greater than 0.5 megohm, the insulation test of the cable body 7 is normal. The linkage plate 8235 is driven to rotate by the third motor 8234 to change the positions of the first meter pen tip 8237 and the second meter pen tip 8238 to meet the different positions of the ground wire, the live wire and the neutral wire at the end of the cable body 7, so that the transformed first meter pen tip 8237 and the second meter pen tip 8238 can contact the ground wire and the neutral wire, or the neutral wire and the live wire;
