Therefore, in order to avoid the above-mentioned technical problems, it is indeed necessary to provide a power grid line laying construction device to overcome the defects in the existing technology.

[0030] Example: Figure 1-3As shown, this utility model provides a technical solution, a power grid line laying construction device, including a mobile laying trolley 1, with universal wheels 2 installed at equal intervals at both ends of the mobile laying trolley 1, and a conveying and pressing mechanism 3 movably arranged on the mobile laying trolley 1. The conveying and pressing mechanism 3 includes an extension plate 301, an L-shaped positioning plate 302, a drive motor 303, a limit anti-deviation rod 304, a lifting slide plate 305, a tension spring 306, a clamping wheel 307, a limit frame 308, an electric telescopic rod 309, a pressing slide frame 310, a pressing frame 311, and a pressing wheel 312.

[0031] One end of the mobile laying trolley 1 is connected to an extension plate 301, and L-shaped positioning plates 302 are symmetrically connected to the top of the extension plate 301. A drive motor 303 is installed at one end of each L-shaped positioning plate 302.

[0032] The tops of the two L-shaped positioning plates 302 are symmetrically engaged with limit anti-deviation rods 304. The outer sides of the two limit anti-deviation rods 304 located on the same side are movably sleeved with lifting slide plates 305, and tension springs 306 are engaged between the lifting slide plates 305 and the L-shaped positioning plates 302.

[0033] Clamping wheels 307 are rotatably connected between the two L-shaped positioning plates 302 and between the two lifting slide plates 305. In order to transport the wires, the drive motor 303 is powered by an external power source, and one end of the output shaft of the drive motor 303 is connected to one end of the shaft of a clamping wheel 307. A baffle is snapped into the top of the limit anti-deviation rod 304.

[0034] The bottom end of the extension plate 301 is snapped with a limit frame 308, the bottom end of the limit frame 308 is snapped with an electric telescopic rod 309, the bottom end of the electric telescopic rod 309 is bolted to a downward sliding frame 310, the bottom end of the downward sliding frame 310 is bolted to a wire pressing frame 311, and the wire pressing frame 311 is rotatably connected to a wire pressing wheel 312 inside. In order to facilitate the laying of wires, both ends of the downward sliding frame 310 are slidably connected to the inner wall of the limit frame 308. The electric telescopic rod 309 is powered by an external power source.

[0035] The top of the mobile laying trolley 1 is equipped with a wire roll support adjustment mechanism 4, which includes a rectangular slide 401, a bidirectional adjustment screw 402, a translation adjustment block 403, a wire roll support plate 404, a wire vertical frame 405, and a wire roller 406.

[0036] The top of the mobile laying trolley 1 is provided with a rectangular slide groove 401. The inner wall of the rectangular slide groove 401 is symmetrically rotatably connected with bidirectional adjusting screws 402. The outer sides of the two bidirectional adjusting screws 402 are threadedly connected with translation adjusting blocks 403. The top of the translation adjusting blocks 403 is locked with a wire roll support plate 404. In order to change the distance between the two wire roll support plates 404, both ends of the bidirectional adjusting screws 402 pass through both ends of the mobile laying trolley 1, and both ends of the bidirectional adjusting screws 402 are locked with knobs. The rotation directions of the threads at the outer ends of the bidirectional adjusting screws 402 are opposite.

[0037] A wire guide frame 405 is bolted to one side of the rectangular chute 401 at the top of the mobile laying trolley 1.

A placement groove is opened at the top of the wire coil support plate 404.

[0038] The working principle and usage process of this utility model are as follows: First, the wire roll to be laid is placed on the wire roll support plate 404. At the same time, the bidirectional adjusting screw 402 is rotated, pushing the two translation adjusting blocks 403 to slide synchronously relative to each other along the inner wall of the rectangular slide groove 401. This changes the distance between the two wire roll support plates 404, making it easier to support and lift wire rolls of different lengths, thus improving adaptability. In addition, the wire vertical frame 405 and the wire roller 406 work together to guide the wire conveying and prevent the wire from getting stuck.

[0039] Next, one end of the wire on the wire coil is passed through the wire roller 406 and clamped between the two clamping wheels 307. At the same time, the tension spring 306 is contracted to pull the lifting slide plate 305 and one clamping wheel 307 to slide up and down along the limit anti-deviation rod 304, adjusting the distance between the two clamping wheels 307 to facilitate clamping and fixing wires of different sizes. Then, with the cooperation of the drive motor 303, the clamping wheel 307 is driven to rotate to facilitate the conveying of the wire.

[0040] Finally, after one end of the wire passes through the clamping wheel 307, it goes around the pressure wheel 312 and, with the help of the electric telescopic rod 309, pushes the lowering slide frame 310, the pressure frame 311 and the pressure wheel 312 to slide down, pressing the wire firmly onto the ground, so that the wire is laid when the mobile laying trolley 1 moves.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
