[0054] The following will be described in detail with reference to the accompanying drawings. Figures 1-6 The application is further described in detail.

[0055] The embodiment of the application discloses an auxiliary device for laying power tunnel cable.

[0056] Referring to Figure 1 and Figure 4 An auxiliary device for laying power tunnel cable comprises a device housing 1, a clamp 4, a guide assembly 2 and a fixing assembly 3.

The fixing assembly 3 is arranged on the device housing 1, and the fixing assembly 3 is used for stably installing the device housing 1 on the support.

[0058] When the auxiliary device for laying power tunnel cable is used, the device housing 1 is sleeved on the support, the support is arranged in the mounting hole 11, the device housing 1 abuts against the clamp 4, then the cable is laid on the guide assembly 2 by a cable tractor, the cable is guided and limited by the guide assembly 2, wear and damage of the cable caused by the support during laying of the power tunnel cable are avoided, and the cable is prevented from being twisted and dropped during turning section construction.

[0059] Referring to Figure 2 , Figure 3 and Figure 5 The guide assembly 2 comprises a mounting seat 21, a guide wheel 22, an electric telescopic rod 24, a guide block 25 and an auxiliary guide 23.

[0060] The guide block 25 is fixedly installed on the device shell 1, the guide block 25 is shaped as a triangular prism, a through slot 251 is formed in the guide block 25, the mounting seat 21 is slidingly installed in the through slot 251, and the guide wheel 22 is rotatably installed on the mounting seat 21. The electric telescopic rods 24 are provided in two, the fixed ends of the two electric telescopic rods 24 are symmetrically and fixedly installed on the device shell 1, and the movable ends of the electric telescopic rods 24 are fixedly connected with the mounting seat 21.

[0061] The length of the electric telescopic rod 24 is adjusted to be elongated, so that the height of the guide wheel 22 is adapted to the height of the cable tractor, and meanwhile, the cable is prevented from being in contact with the guide block 25. The cable is laid on the guide wheel 22 by the cable tractor. In the process of laying the cable, the cable is rolled on the guide wheel 22, so that the friction of the surface of the cable in the laying process is reduced, and the surface of the cable is prevented from being abraded and damaged in the laying process. The cable is guided by the guide wheel 22, so that the cable is prevented from being directly in contact with the support, and the traction force of the cable tractor on the cable is reduced.

[0062] After the laying of the cable is completed, the length of the electric telescopic rod 24 is adjusted to be shortened, so that the guide wheel 22 enters the through slot 251, and the cable is in abutment with the guide block 25. Under the action of gravity, the cable slides along the inclined surface of the guide block 25 and falls into the clamp 4, so that the labor for manually carrying the cable to the clamp 4 is saved, and the labor is saved.

[0063] The auxiliary guide 23 is provided in two groups, the two groups of auxiliary guides 23 are symmetrically arranged on the device shell 1, and the auxiliary guide 23 comprises a push rod 231, a first guide rod 232, a second guide rod 233, an auxiliary telescopic rod 2312 and a first reset spring 2313.

[0065] When the cable is laid, the cable is limited by the first guide rod 232 and the second guide rod 233, so that the cable can always abut on the guide wheel 22 in the laying process. Meanwhile, the positions of the first guide rod 232 and the second guide rod 233 can be adaptively adjusted by the adaptive adjustment of the auxiliary telescopic rod 2312 and the first reset spring 2313, so that the cable can be limited in the turning section construction, the stability in the laying process of the cable is improved, and the cable is prevented from being twisted and falling off in the turning section construction.

[0066] With reference to Figure 2 、 Figure 3 and Figure 6 , the auxiliary guide 23 further comprises a third guide rod 234, a rotating motor 235, a straight gear 236, a rack 237 and a second return spring 238.

[0077] When using a power tunnel cable laying auxiliary device, the staff can hold the rotating rod 37 to lift the device shell 1 and set the device shell 1 on the support, which is convenient for the staff to install the device shell 1.

[0078] After the device shell 1 is sleeved on the support, the worker rotates the rotating rod 37, the rotating rod 37 rotates and drives the fixed block 36 to rotate, the fixed block 36 rotates and drives the driving bevel gear 31 to rotate, the driving bevel gear 31 rotates and drives the first clamping bolt 32 to move towards the support, so that the clamping block 35 abuts against the support.
