[0045] Reference Figure 1 、 Figure 3 and Figure 5The utility model provides an embodiment in which a controller 21 is fixedly connected to the front side of the top left end of the sliding plate 1, a level 22 is fixedly connected to the right side of the top left end of the sliding plate 1, a warning light 18 is fixedly connected to the top of the force-bearing plate 6, an extrusion ring 24 is fixedly connected to the right end of the force-bearing plate 6, pipes 19 are fixedly connected to both sides of the extrusion ring 24, and a pipe jacking machine 20 is fixedly connected to the right side of the pipe 19;

[0046] Specifically, a controller 21 is fixedly connected to the front side of the left top of the sliding plate 1. This controller 21 can operate and adjust the device to achieve precise control of each component of the device. A spirit level 22 is fixedly connected to the right side of the left top of the sliding plate 1.

The extrusion ring 24 is used to facilitate the force plate 6 to squeeze and push the pipe 19. The pipe 19 is connected to the right side of the extrusion ring 24, and the right side is connected to the pipe jacking machine 20.

[0047] Working principle: When the device is pushing, first, the hydraulic rod 15 fixed on the force-bearing plate 6 is extended. The weight of the force-bearing plate 6 and the weight it bears are supported by the support rod 7 and the slider 4. The left side of the hydraulic rod 15 passes through the outer wall of the force-bearing plate 6 and is fixed to the left end of the sliding plate 1. When the hydraulic rod 15 is extending, the force-bearing plate 6 moves to the right, pushing the pipe 19 to the right end. The sliding plate 1 can slide on the load-bearing plate 12 due to the connected slide rail 10 and the load-bearing plate 12 below. When the force-bearing plate 6 moves to the maximum limit, the hydraulic rod 29 participates in the work. The hydraulic rod 29 is fixed on the sliding plate 1, and the left end passes through the sliding plate 1. Therefore, the left end of the hydraulic rod 29 slowly extends and pushes toward the wall, so that the sliding plate 1 fixed to the outer wall can be moved to the right, thereby extending the two ends.

[0048] Moreover, when the pipe 19 needs to be placed on the device for advancement, before placement, the top of the splint 203 is in an open and closed state due to the tension applied by the spring 206 at the bottom, and the pipe 19 can be directly placed into the inner wall of the two splints 203 from the upper opening. Then, the weight of the pipe 19 itself is greater than the tension released by the spring 206, so that the two splints 203 clamp and fix the pipe 19. Then, the force-bearing plate 6 drives the extrusion ring 24 fixed on its outer wall to push the pipe 19 to move to the right. Since there are multiple rollers 207 at the connection between the pipe 19 and the splint 203, when the force-bearing plate 6 pushes the pipe 19, the clamped pipe 19 can still move to the right.

[0049] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
