[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In this embodiment, the front, rear, left, right, top and bottom are represented by Figure 1 Describes the datum surface. Figure 1-Figure 6 , the utility model provides a technical solution:

[0024] A power test line take-up device comprises a base frame 1, two side baffles 2 are fixedly installed in the base frame 1, a winding roller 3 with a threading hole is rotatably installed between the two side baffles 2, semi-annular slide grooves 21 are opened on the diverging surfaces of the two side baffles 2, L-shaped sliders 4 are slidably installed in the slide grooves 21, a cross bar 5 is fixedly installed between the two L-shaped sliders 4, the bottom size of the L-shaped slider 4 is adapted to the size of the slide groove 21, after the cross bar 5 is installed between the two L-shaped sliders 4, the two L-shaped sliders 4 can stably slide in the corresponding slide grooves 21, and the outer surface of the cross bar 5 is sleeved with a guide device 6, which is used to guide the test line when the line is erected and prevent the test line from contacting the metal edge of the device to cause wear of the external insulation skin.

[0025] It should be noted that, combined with Figure 1 and Figure 4As shown, the guide device 6 includes a half set A61 and a half set B62, the rear end of the half set A61 is rotatably connected with the rear end of the half set B62 through a rotating shaft, and after the half set A61 and the half set B62 are buckled together, a C-type plate 63 is clamped and installed between the front ends of the two, and mounting holes are penetrated through the C-type plate 63, the half set A61 and the half set B62, and bolt and nut assemblies (bolts and matching nuts) are installed between the three through the mounting holes, and two rubber guide wheels 64 are rotatably installed on the upper surface of the C-type plate 63, and a rotating shaft is rotatably installed in the rubber guide wheel 64, and adapter seats are fixedly installed between the two ends of the rotating shaft and the C-type plate 63, and the rubber guide wheels 64 are rotatably installed with the C-type plate 63 in this way. Attention should be paid during installation. During installation, it is necessary to ensure that the installation state of the two rubber guide wheels 64 is as follows Figure 4 As shown, the ends of the two rubber guide wheels 64 are slightly fitted together. When the cable passes between the two rubber guide wheels 64, it can avoid the cable from being separated from the rubber guide wheels 64 and contacting the C-shaped plate 63 when being pulled to the left and right sides.

[0026] In the power test wiring operation, first, before the wiring operation begins, the cable end needs to be placed between the two rubber guide wheels 64. After completing this preparation step, the cable can be pulled according to the actual wiring direction required. In the process of pulling the cable, the guide device 6 will slide flexibly on the outer surface of the cross bar 5 according to the pulling direction, so as to meet the direction change requirements during the wiring process. When it is necessary to perform the wiring operation in the backward direction, the L-shaped slider 4 can be pulled in the wiring direction through the cross bar 5 to adjust it to a suitable position in the slide groove 21, thereby meeting the wiring requirements in this specific direction.

[0027] Compared with the existing technology, this wiring method can achieve multi-directional dynamic guidance of the test cable. This feature effectively avoids direct contact between the cable and the metal component, significantly reduces the degree of wear of the insulation layer, and thus extends the service life of the cable. At the same time, this method also improves the convenience of wiring operations, reduces obstacles in the operation process, and improves the overall wiring efficiency.

[0028] Combination Figure 3 and Figure 5 As shown, threaded heads 51 are integrally formed at both ends of the cross bar 5, and through openings 41 are penetrated on the left surface of the L-shaped slider 4. When installing the cross bar 5 and the L-shaped slider 4, it is necessary to first penetrate the threaded heads 51 at both ends of the cross bar 5 through the corresponding through openings 41 respectively, and then nuts 52 are screwed and installed on the outer surfaces of the threaded heads 51. By locking the nuts 52, the cross bar 5 is fixedly installed between the two L-shaped sliders 4.

[0029] After the test is completed, when the line is collected, in order to ensure that the position of the cross bar 5 is fixed and prevent it from sliding randomly during the collection process, Figure 5 and Figure 3As shown, a threaded hole 42 is formed through the left surface of the left L-shaped slider 4, and a clamping bolt 43 is threadedly installed in the threaded hole 42. The left end of the clamping bolt 43 is fixedly connected to an operating handle, and the operating handle can be used to drive the clamping bolt 43 to rotate. When the right end of the clamping bolt 43 is in contact with the outer surface of the left side baffle 2, the left L-shaped slider 4 can be fixed, thereby keeping the position of the cross bar 5 fixed.

[0030] In order to facilitate the rotation and winding of the winding roller 3, a hand wheel 31 is fixedly installed on the right surface of the winding roller 3. The winding roller 3 can be driven to rotate by operating the hand wheel 31, making the cable winding work more convenient and labor-saving.

[0031] In order to enhance the stability of the two side baffles 2 , three reinforcing rods 22 are fixedly installed between the two side baffles 2 .

[0032] Finally, in order to prevent the roller 3 from rotating randomly during the carrying process and affect the cable winding effect, a fixing plate 7 is fixedly installed on the left surface of the side baffle 2 on the left side, and pin holes are penetrated through the upper surface of the fixing plate 7 and the outer surface of the left end of the roller 3. A pin rod 8 is inserted and installed between the two pin holes, and the roller 3 is fixed by inserting the pin rod 8 into the pin hole. In this way, when the cable winding device is carried, the roller 3 can be effectively prevented from rotating randomly, ensuring the stability of the cable winding device, and thus ensuring that the cable winding effect is not disturbed during the carrying process.
