[0040] In the prior art, the cable laying device includes a cable, a housing, and an electric wheel. The electric wheel is arranged at the bottom of the housing, and the housing is connected to the cable. The housing is placed in the sewer, and the housing is driven to move in the sewer by the electric wheel. The cable on the housing moves along with the housing. When the cable moves from one end of the sewer to the other end, the laying of the cable in the sewer is completed.

[0041] In the above solution, the electric wheels on the housing are directly placed at the bottom of the sewer. Since the situation in the sewer is complex, the ground in the sewer may be uneven, and the cable laying device may tip over during movement, resulting in the suspension of cable laying. Moreover, it is necessary to take out the cable laying device and rearrange it before cable laying can be carried out again. Therefore, the original cable laying device has low laying efficiency.

[0042] The present application provides a cable laying device. By providing telescopic rods on opposite sides of the housing, the electric wheels are abutted against the inner walls on both sides of the pipeline through the telescopic rods, so that the housing is more stable during movement and is not prone to tipping over, which affects the laying progress. The present application will be further described below with reference to the accompanying drawings.

[0043] Among them, Figure 1 is a schematic structural diagram of the cable laying device provided by an embodiment of the present application. Figure 2 is Figure 1 a schematic structural diagram of the traction assembly in Figure 3 is Figure 2 a partial schematic structural diagram of the locking assembly in Figure 4 is Figure 2 a schematic structural diagram of the telescopic rod in Figure 5 is Figure 4 a schematic structural diagram of the bottom of the support rod in

[0044] Combined with Figure 1 and Figure 2 as shown, an embodiment of the present application provides a cable laying device, which is applied to a pipeline and includes a wire pay-off assembly 100, a traction assembly 200, and a locking assembly 300. The traction assembly 200 includes a housing 210, at least two telescopic rods 220, and at least two electric wheels 230.

[0045] The locking assembly 300 is arranged on the housing 210, and the locking assembly 300 is connected to the cable on the wire pay-off assembly 100.

[0046] Two telescopic rods 220 are arranged on opposite sides of the housing 210. The ends of the telescopic rods 220 are provided with electric wheels 230. The housing 210 is abutted against the inner side walls on both opposite sides of the pipeline through the electric wheels 230. The electric wheels 230 are used to drive the housing 210 to move along the pipeline so as to drive the cable to move along the pipeline.

[0047] The housing 210 is abutted against the inner walls on both sides of the pipeline through the electric wheels 230 on the telescopic rods 220, improving the stability of the housing 210 during movement and avoiding the situation where the housing 210 tips over and causes the suspension of laying.

[0048] Among them, the wire laying assembly 100 is placed outside the pipeline. The wire laying assembly 100 is pre-wound with wires and cables, such as power cables and optical cables. During the movement of the traction assembly 200, the wire laying assembly 100 will release the wires to ensure the continuity of wire laying.

[0049] The telescopic rod 220 is used to adjust the relative distance between the electric wheel 230 and the housing 210 so that the housing 210 can adapt to pipelines of different widths.

[0050] The working steps of the embodiment of the present application are as follows: First, place the wire laying assembly 100 at the pipeline opening. After connecting the wire to the housing 210 through the locking assembly 300, put the housing 210 into the pipeline. Operate the telescopic rod 220 to make the electric wheel 230 fully abut against the side walls on both sides, and then turn on the electric wheel 230 to drive the housing 210 to move to the other end of the pipeline, thus completing the laying of the wire in the pipeline. For the case of water accumulation in the pipeline, the electric wheel 230 can be abutted against the horizontal sides of the pipeline to prevent the wire from contacting the water.

[0051] Exemplarily, three telescopic rods 220 can be provided, two of which are located on the same side of the housing 210 and the other is located on the opposite side of the housing 210.

[0052] Exemplarily, four telescopic rods 220 can be provided, with two provided on each side of the housing 210.

[0053] In the embodiment of the present application, the wire laying assembly 100 includes a base 110, a first reel 120, and a first motor 130.
