Problems solved by technology

[0005] The inventors found that in the traditional construction method, the cable is often impacted or squeezed by foreign objects, and the cable protective layer is worn out, and the non-mechanical deployment method based on manpower is inefficient, and the construction personnel may be squeezed by the cable. , tripping and other safety risks; ordinary mechanical deployment methods have many disadvantages for complex terrain areas and long-distance cable deployment, such as the need for auxiliary cable transportation, multiple replacement of pay-off racks or pay-off devices, etc.

Embodiment 1

[0038] In a typical embodiment of the present invention, such as Figure 1-Figure 6 As shown, a long-distance and large-diameter cable deployment system under complex terrain is proposed, including a vertical cable deployment device, an auxiliary engineering vehicle 1 and a guide pulley block 5 .

[0039] Among them, the vertical cable deployment device is set on the flat plate of the auxiliary engineering vehicle 1, mainly used for the support of the cable reel 2, the guide pulley block 5 is arranged at the end of the boom of the auxiliary engineering vehicle 1, and the cable 6 wound on the cable reel 2 Through the guiding effect of the guide pulley group 5, it is laid in the excavated cable trench 7, and the cable bracket 8 is also provided in the cable trench 7, which not only facilitates the classified laying of the cables 6, but also effectively prevents the heat released by the cables from affecting the performance of the cables. Ampacity.

[0040] Such as figure 2 As...

Embodiment 2

[0061] In another typical embodiment of the present application, the method for using the long-distance and large-diameter cable deployment system under complex terrain as described in Embodiment 1 is provided, specifically as follows:

[0062] Step 1: Design according to the size of the cable reel 2, make and process one piece each of the base 4 and the rotating bracket 3, except for the assembly surface, the outer surface of the parts is treated with paint and anticorrosion; the CE standard thrust bearing is used, and the assembly is completed Vertical cable deployment device;

[0063] Step 2: Place the assembled vertical cable deployment device on the center of the auxiliary engineering vehicle 1 flat panel, fix the base 4 on the auxiliary engineering vehicle 1 flat panel, and keep the rotating bracket 3 flexibly rotating in the horizontal direction;

[0064] Step 3: Calculate the length of the deployed cable 6 according to the design drawings, deploy the weight of the cabl...

Description

technical field [0001] The invention relates to the technical field of power transmission and transformation engineering, in particular to a system and method for deploying long-distance and large-diameter cables under complex terrain. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] In the construction of long-distance and large-diameter cable lines in complex terrain areas such as mountainous areas, cable deployment is an important part of the construction. Due to factors such as large-diameter cables and heavy weight per unit length, narrow and long working surfaces, and complex terrain in the construction area, construction difficulty and quality risks Larger, scientific and effective construction methods have an important impact on construction efficiency and quality. [0004] During the deployment of long-distance and large-diameter cables, v...
