The traction wire is then pulled, releasing the cable from the cable roller.

[0003] However, the prior art has the following defects:

[0004] Due to the complex terrain of the construction site, when the cable is dragged and turned, it is very easy for the cable to get stuck on the edge of the cable roller and cannot be dragged, which can easily damage the cable surface. Utility Model Content

[0005] In order to solve the technical problem that cable dragging is not smooth and laborious, the utility model provides an auxiliary tool for power cable installation.

[0030] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0031] An auxiliary tool for installing a power cable, comprising a fixing base 1 and a steering mechanism, wherein the steering mechanism is arranged on the fixing base 1 and a bracket 9 is fixed on the steering mechanism;

[0032] The smoothing mechanism is arranged in the bracket 9. The smoothing mechanism includes two arc rollers 15 and a guide unit. One end of the two arc rollers 15 is connected to the bracket 9 through the guide unit, and the other end of the arc roller 15 is provided with a driving mechanism, which is arranged on the steering mechanism.

[0033] Specifically, such as Figure 2 The drive mechanism drives the two curved rollers 15 to move horizontally in conjunction with the guide unit, securing the cable between the two curved rollers 15. In actual use, the horizontal movement spacing of the two curved rollers 15 can be controlled according to the cable diameter to achieve position control for cables of varying diameters. The steering mechanism flexibly drives the smoothing mechanism and guide mechanism to rotate according to the cable's movement angle, ensuring the cable moves smoothly between the two curved rollers 15 to the greatest extent possible without severe bending.

[0034] Further, such as Figure 2 and Figure 4 The steering mechanism includes an inner plate 2 and a sleeve plate 3. A plurality of movable grooves 4 are opened on the circumference of the inner plate 2. A spring 5 is fixed in the movable groove 4, and a limit block 6 is fixed near the outer end of the spring 5 and the limit block 6 is rolled and embedded with a ball 7. A plurality of limit grooves 8 are opened on the inner circumference of the sleeve plate 3, and the ball 7 is in contact with the limit groove 8.

[0035] When the cable is dragged by the worker and needs to turn further, the pressure given by the cable will cause the arc roller 15 to drive the bracket 9 to rotate, and the sleeve disc 3 rotates on the inner disc 2. The inner wall of the sleeve disc 3 first compresses the ball 7 to drive the limit block 6 into the movable groove 4, and compresses the spring 5 until the ball 7 reaches the adjacent limit groove 8. Under the rebound of the spring 5, the ball 7 will contact the limit groove 8 again, completing the limitation of the sleeve disc 3.

[0036] It should be noted that when the angle of the cable dragged by the worker changes significantly compared to the previous angle, the cable will force the sleeve disc 3 to rotate. When the dragging angle is within the normal range, the elastic potential energy of multiple springs 5 ​​can ensure that the inner disc 2 and the sleeve disc 3 remain stationary, thereby ensuring the overall stability of the device.

[0037] Furthermore, the smooth mechanism includes a round rod 13 and a pointer 14. One end of the round rod 13 is rotatably connected to the arc roller 15, and the other end of the round rod 13 is connected to the pointer 14. A scale is also provided above the bracket 9, and the pointer 14 is in contact with the scale.

[0038] For details, please refer to Figure 1 and Figure 3 When the arc roller 15 drives the pointer 14 to move, the pointer 14 moves on the scale, and the distance between the two arc rollers 15 can be observed more intuitively. It is suitable for cables of different diameters and improves the convenience of workers.

[0039] At the same time, since the round rod 13 and the arc roller 15 are rotationally connected, the cable can drive the two arc rollers 15 to rotate when passing through the two arc rollers 15, which can reduce the friction between the cable and the arc rollers 15 and ensure that the cable moves more smoothly.

[0040] It should be noted that, driven by the driving mechanism, the two arc rollers 15 move synchronously, that is, the zero point of the scale is set in the middle, and the two pointers 14 move synchronously towards or away from each other, which is more convenient for observation.

[0041] Furthermore, the guide unit includes a guide groove 10, a guide rail 11 and a slider 12. The guide groove 10 is opened through the bracket 9. The two guide rails 11 are symmetrically opened on the bracket 9 and connected to the guide groove 10. The slider 12 is fixed on the round rod 13, and the slider 12 slides on the guide rail 11.

[0042] Specifically, refer to Figure 2 and Figure 3 When the arc roller 15 moves, it drives the round rod 13 to move horizontally in the guide groove 10, so that the arc roller 15 can only move horizontally in a straight line.

[0043] Furthermore, the driving mechanism includes a connecting rod 16, a rack 17, a gear 18, a telescopic tube 19 and a turntable 20. One end of the connecting rod 16 is fixed on the arc roller 15, and the other end of the connecting rod 16 is rotatably connected to the rack 17. One end of the telescopic tube 19 is fixed in the sleeve 3 through a bearing, and the other end of the telescopic tube 19 is fixed to the turntable 20. The gear 18 is fixed on the telescopic tube 19, and the gear 18 is engaged with the two racks 17.

[0044] For details, please refer to Figure 1 and Figure 2 When the turntable 20 rotates, the two racks 17 can be driven to move relative to each other. Under the connection of the connecting rod 16, the two arc rollers 15 can also be driven to move stably to limit the cable.

[0045] It should be noted that the telescopic tube 19 is a telescopic tube, which can be divided into an upper tube and a lower tube, and the internal structure of the telescopic tube 19 is a card-type telescopic tube. While telescoping up and down, the upper tube can also drive the lower tube to rotate, which can ensure that when the turntable 20 rotates, the gear 18 can also rotate stably.

[0046] Furthermore, the driving mechanism also includes a limiting unit, which includes an insertion rod 21 and a slot 22. One end of the insertion rod 21 is fixed on the turntable 20, and a channel 1 is opened on the gear 18 for the insertion rod 21 to pass through. The other end of the insertion rod 21 passes through the channel 1 and is inserted into the slot 22. Multiple slots 22 are opened circumferentially in the sleeve 3.

[0047] For details, please refer to Figure 3 and Figure 5When the turntable 20 needs to be rotated, first pull the turntable 20 upward to move the insertion rod 21 away from the slot 22 and then rotate it. After rotation, press the turntable 20 so that the insertion rod 21 can be inserted into one of the slots 22 to ensure the stability of the position of the turntable 20 and the gear 18, and determine the stable distance between the two arc rollers 15 to limit the cable.

[0048] It should be noted that channel 1 is only for the vertical movement of the insertion rod 21, and its size matches that of the insertion rod 21.

[0049] The implementation principle of the power cable installation auxiliary tool of the present application is as follows: first, adjust the spacing between the two curved rollers 15 according to the diameter of the cable. When adjusting, hold the turntable 20 and pull it upward to extend the telescopic tube 19, driving the insertion rod 21 away from the slot 22. Then rotate the turntable 20 to rotate the gear 18. Under the meshing of the gear 18 and the two racks 17, the two racks 17 are driven to move closer or farther. The connecting rod 16 and the curved roller 15 are also driven to move together, so that the round rod 13 moves in the guide groove 10, and the slider 12 slides in the guide rail 11. The two pointers 14 move on the scale above the bracket 9, thereby judging the spacing between the two curved rollers 15 and ensuring that the spacing is the same as the cable diameter. Press the turntable 20 downward to drive the insertion rod 21 to be reinserted into the slot 22 to limit the gear 18 and the two racks 17.

[0050] After the adjustment is completed, the cable is passed between the two arc rollers 15 and contacts the arc rollers 15. When the cable is pulled, the arc rollers 15 rotate, and the cable can be pulled to any angle for laying operations.

[0051] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
