[0002] In modern urban construction and infrastructure renovation, laying underground cables is a vital task. Traditional cable laying methods often require a lot of manpower and material resources, which is not only inefficient, but also difficult to ensure the laying quality. Specifically, traditional methods usually involve tedious steps such as manually digging cable trenches, manually laying cables, and then manually backfilling soil, which is not only time-consuming and labor-intensive, but also poses safety risks.

[0003] The existing patent with publication number CN109980579A provides an underground cable laying device, which only has the function of laying out the cable, so the construction efficiency is not high. In addition, in the traditional cable laying process, the tension control of the cable is often not accurate enough, which can easily cause the cable to be damaged during the laying process or become loose after laying, affecting the service life and safety of the cable. At the same time, when laying the compression plate to protect the cable from external force damage, the traditional method often relies on manual handling and positioning, which is not only inefficient, but also difficult to achieve accurate laying of the compression plate;

The bottom plate 1 is made of a high-strength alloy material, which not only ensures the load-bearing capacity of the device, but also enhances its corrosion resistance and wear resistance through special process treatment, ensuring stable operation in various complex environments. The arrangement of the wheels enables the device to be easily moved on the ground, which is convenient for laying operations at different work locations. Two bulldozers 7 for covering the soil pile are symmetrically arranged at the rear end of the bottom plate 1. The surface of the earth plate 7 is covered with a wear-resistant layer to reduce the loss caused by friction with the soil. The bulldozer plate 7 is inclined and tilted from one end connected to the slide plate 8 toward the other bulldozer plate 7. Two second mounting plates 6 are fixedly installed on the upper end of the bottom plate 1. An adjustment component for adjusting the distance between the two bulldozer plates 7 is arranged between the two second mounting plates 6. The adjustment component includes a double-headed screw 9 rotatably connected between the two second mounting plates 6. Both ends of the double-headed screw 9 are threadedly connected to the slide plate 8. The slide plate 8 is fixedly connected to the bulldozer plate 7. A second motor 5 is fixedly installed on the side wall of one of the second mounting plates 6. The output shaft of the second motor 5 is coaxially fixed with the double-headed screw 9. The threads at both ends of the double-headed screw 9 are arranged in opposite directions.

[0035] A material storage box 11 is fixedly installed on the upper end of the bottom plate 1. A discharge port adapted to the material storage box 11 is opened on the upper end of the bottom plate 1 for discharging the pressure-resistant plate. A conveyor belt 28 is rotatably connected to the lower end of the bottom plate 1. Two adjustment push rods 29 are symmetrically arranged at the lower end of the bottom plate 1. The telescopic ends of the two adjustment push rods 29 are rotatably connected to the side walls of the adjustment push rods 29. The position of the conveyor belt 28 corresponds to the discharge port. Openings are opened on both sides of the material storage box 11. A closing assembly for closing the discharge port is arranged inside the opening. The closing component can automatically open or close the discharge port according to the progress of cable laying. The closing component includes a first mounting plate 3 fixedly mounted on the upper end of the bottom plate 1. A first motor 4 is fixedly mounted on the side wall of the first mounting plate 3. A screw 10 is fixedly mounted on the end of the output shaft of the first motor 4. A closing plate 12 is threadedly connected to the screw 10. The other end of the screw 10 is rotatably connected to the side wall of the material storage box 11. The closing plate 12 is an L-shaped plate, and the closing plate 12 is located in the opening, which can block the discharge port and control the discharge of the pressure-resistant plate.

[0036] Two vertical plates 22 are fixedly installed on the upper end of the bottom plate 1, and a cable reel 24 is rotatably connected between the two vertical plates 22. A third motor 23 for driving the cable reel 24 to rotate is fixedly installed on the side wall of one of the vertical plates 22. A fixed plate 21 is fixedly installed between the two vertical plates 22, and a tensioning assembly for tightening the cable is arranged on the fixed plate 21. The tensioning assembly includes a slide bar 19 that passes through the fixed plate 21, a baffle 20 is fixedly installed on one end of the slide bar 19, and a tensioning wheel mounting seat 16 is fixedly installed on the other end. The tension wheel 17 is rotatably connected inside, the tension wheel mounting seat 16 is elastically connected to the fixed plate 21 through a spring 18, a mounting column 27 is fixedly installed on the side wall of the fixed plate 21, and a guide wheel mounting seat 26 is fixedly installed on the other end of the mounting column 27, and a guide wheel 25 is rotatably connected inside the guide wheel mounting seat 26, and the guide wheel 25 is located directly below the tension wheel 17. The cable reel 24 is designed with an automatic tension control system, which works in conjunction with the third motor 23 to automatically adjust the rotation speed according to the speed at which the cable is pulled out to avoid excessive relaxation or tension of the cable;

[0037] A cable laying hole 14 for the cable to pass through is opened on the base plate 1. Two guide wheel mounting seats 13 are fixedly installed on the upper end of the base plate 1. A guide wheel 15 is rotatably connected between the two guide wheel mounting seats 13. The position of the guide wheel 15 corresponds to the cable laying hole 14. The design of the guide wheel 25 and the guide wheel mounting seat 26 effectively guides the cable into the cable laying hole 14 and reduces friction damage. The surface of the guide wheel 15 is also covered with wear-resistant and anti-slip material to protect the cable from scratches.

[0038] The present invention can explain its functional principle through the following operation mode:

[0039] When the device arrives at the laying site, the device can be stably placed in the working position by adjusting the wheel 2 or using other auxiliary equipment. The cable to be laid is wound on the cable reel 24. The cable reel 24 is driven to rotate by the third motor 23 to release the cable. When the cable passes through the tensioning assembly, the tensioning wheel 17 generates a certain tension on the cable under the action of the spring 18 to keep the cable taut and avoid relaxation. The guide wheel 25 is located directly below the tensioning wheel 17 and is used to guide the direction of the cable to ensure that the cable can accurately pass through the cable laying hole 14. The cable laying hole 14 allows the cable to pass from under the bottom plate 1 and be directly laid underground. The guide wheel 15 is located above the cable laying hole 14 and is used to further organize the cable to ensure that the cable is laid neatly.

[0040] Subsequently, the material box 11 is equipped with an anti-pressure plate. When the anti-pressure plate needs to be laid, the opening and closing of the discharge port is controlled by the closing component. The first motor 4 drives the screw 10 to rotate, so that the threaded closing plate 12 moves in the opening, thereby opening or closing the discharge port. The anti-pressure plate falls onto the conveyor belt 28 through the discharge port. The conveyor belt 28 conveys the anti-pressure plate to the specified position. The telescopic end of the push rod 29 can be adjusted to adjust the inclination angle of the conveyor belt 28 to ensure that the anti-pressure plate can be accurately laid above the cable.

[0041] After the anti-pressure plate is laid, the two inclined bulldozer plates 7 at the rear end of the device are used to cover the excavated soil pile after the cable is laid. The spacing of the bulldozer plates 7 can be adjusted by an adjustment component, specifically by driving the double-headed screw 9 to rotate through a second motor 5. Since the threads at both ends of the double-headed screw 9 rotate in opposite directions, the two slides 8 will move in opposite directions at the same time, thereby driving the bulldozer plates 7 to adjust their spacing to adapt to cable trenches of different widths.

[0042] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.
