Reasonable selection of cable laying methods is very important to ensure the transmission quality, reliability and construction and maintenance of the line.
[0003] Cable laying is an important technical link in power engineering. During the cable laying process, the raw material of the cable is wound on the cable drum. As the laying process continues, the cable on the cable drum is gradually deployed.

The cable drum 1 is an existing well-known public; the pressure wheel 8 can be made of rubber. By installing a close-fitting pressure wheel 8 at the cable release end, the purpose of continuously and neatly unfolding the cable as the frame moves is achieved, which has the characteristics of safety and reliability, facilitates operation, greatly improves work efficiency, and reduces the labor intensity of operators.
[0023] The above-mentioned power cable deployment vehicle can be further optimized and / or improved according to actual needs: As attached Figure 1 , 2 As shown in , 3, 4, 5, and 6, the frame body includes a front frame body 9 and a rear frame body 10, the front end of the left walking shaft 2 is installed at the lower left part of the front frame body 9, the rear end of the left walking shaft 2 is installed at the lower left part of the rear frame body 10, the front end of the right walking shaft 4 is installed at the lower right part of the front frame body 9, and the rear end of the right walking shaft 4 is installed at the lower right part of the rear frame body 10. In this way, it is easy to install and disassemble.
[0024] As attached Figure 1 , 2 As shown in 3, the front frame 9 is an inverted V-shaped frame; the rear frame 10 is an inverted V-shaped frame. The inverted V-shaped frame is more stable, saves more material, and is lighter.
[0025] As attached Figure 1 , 2, 3, and 6, it also includes a front extension arm 11, a rear extension arm 12, and a tensioning rod 13. The left end of the front extension arm 11 is fixedly connected to the upper part of the front frame 9, and a front handle 14 is fixedly connected to the right end of the front extension arm 11. A front connecting column 15 is fixedly connected to the bottom of the front handle 14. A front pressure handle 16 is hinged at the lower part of the front connecting column 15. A first tension spring 17 is connected between the front pressure handle 16 and the front handle 14. The left end of the rear extension arm 12 is fixedly connected to the upper part of the rear frame 10, and the right end of the rear extension arm 12 is fixedly connected to the front handle 14. A rear handle 18 is fixedly connected, a rear connecting column is fixedly connected to the bottom of the rear handle 18, a rear pressure handle is hinged at the bottom of the rear connecting column, a first tension spring 17 is connected between the rear pressure handle and the rear handle 18, a connecting rod 19 is fixedly connected between the front pressure handle 16 and the rear handle 18, a guide wheel 20 is installed at the bottom of the right walking shaft 4 through a bearing seat, a pull rod 21 is fixedly connected to the bracket, one end of the tie rod 13 is fixedly connected to the connecting rod 19, and the other end of the tie rod 13 is fixedly connected to the pull rod 21 around the guide wheel 20. The tension rod 13 is used to pull the pressure wheel 8, so as to adjust the tightness of the pressure wheel 8, so as to achieve the purpose of continuous and orderly unfolding of the cable as the frame moves. The front extension arm 11 and the rear extension arm 12 and the front handle 14 and the rear handle 18 thereon are provided for the operator to grasp, so as to manually push forward. When part of the cables on the cable drum 1 have been released and spread on the ground or in the cable trench, there is a large static friction between this part of the cables and the ground or the cable trench. Based on this static friction, during the pushing process, a pulling effect is formed on the unreleased cables on the cable drum 1, so that the cable drum 1 rotates as it is pushed, thereby continuing to release the cables thereon.
[0026] As attached Figure 1 , 2As shown in , 3, 4, 5, and 6, the bracket includes a front bracket 22 and a rear bracket, the front end of the clamping shaft 7 is installed on the upper part of the front bracket 22, the rear end of the clamping shaft 7 is installed on the upper part of the rear bracket, and a pressure wheel 8 is fixedly installed in the middle of the clamping shaft 7. The left end of the front bracket 22 and the lower left part of the front frame body 9 are hinged together through a hinge shaft 23, and the left end of the rear bracket and the lower left part of the rear frame body 10 are hinged together through a hinge shaft 23. A front connecting short section 24 is fixedly connected to the inner side of the middle part of the front frame body 9, and a second tension spring 25 is connected between the front connecting short section 24 and the clamping shaft 7. A rear connecting short section 26 is fixedly connected to the inner side of the middle part of the rear frame body 10, and a second tension spring 25 is connected between the rear connecting short section 26 and the clamping shaft 7. The pull rod 21 is fixedly connected between the right end of the front bracket 22 and the rear bracket. The second tension spring 25 is used to continuously press the position where the cable is about to leave the cable drum 1 to ensure that the release end is relatively neat. The second tension spring 25 applies pressure to the pressure wheel 8 toward the cable drum 1, so that the pressure wheel 8 exerts a certain pressure on the position where the cable is about to leave the cable drum 1, thereby preventing the cable from expanding and becoming messy due to its own elasticity before it leaves the cable drum 1, which helps to ensure neat laying; in order to overcome the defect that this pressure effect cannot be adjusted, the present invention adds a tensioning rod 13. When it is necessary to loosen this pressure effect appropriately, the front handle 14 and the rear handle 18 are manually grasped to cause the connecting rod 19 to pull the upper end of the tensioning rod 13 upward. Through the conduction of the tensioning rod 13, the pressure wheel 8 is pulled in the direction away from the cable drum 1, so that the pressure effect is relaxed; the guide wheel 20 plays a guiding role; the connecting rod 19 plays a synchronizing role between the front handle 14 and the rear handle 18.
[0027] As attached Figure 2 As shown, the front bracket 22 is an L-shaped bracket; the rear bracket is an L-shaped bracket. The L-shaped bracket is easy to install.
