[0003] However, when using existing pipe jacking machines, they are basically pulled to the collapse area by traction equipment. During traction, the pipe jacking machine is prone to wear due to excessive contact with the pipeline, and multiple pipe jacking machines cannot be spliced and used, which limits the range of the pipe jacking machine.

[0021] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.
[0022] like Figure 1-4As shown, a pipe jacking machine for municipal construction includes a main box 1, two hydraulic rods 2 are installed on the upper and lower parts of the main box 1, and the ends of the two hydraulic rods 2 are commonly connected to a pipe jacking arc plate 3, and moving parts 4 are provided on both sides of the main box 1. The moving parts 4 include an installation box 5, a rotating disk 6 is provided at one end of the installation box 5, and a moving wheel 7 is connected to the outside of the rotating disk 6, a hydraulic cylinder 8 is installed on one side of the interior of the installation box 5, and the telescopic shaft of the hydraulic cylinder 8 passes through the outside of the other side of the installation box 5, and the rotating disk 6 is rotatably connected to the outside of the telescopic shaft.
[0023] By setting the rotating disk 6, the direction of the moving wheel 7 can be rotated so that the moving wheel 7 can be adjusted from the vertical direction to the horizontal direction. In conjunction with the extension and retraction of the hydraulic cylinder 8, the moving wheel 7 can contact the pipe wall, making it convenient to drive the entire pipe jacking machine to move through the moving wheel 7.
[0024] The moving wheel 7 is composed of a U-shaped mounting seat and a wheel body, and the wheel body is rotatably mounted inside the U-shaped seat.
[0025] Snap-on plates 9 are installed on both sides of the front of the main chassis 1 , and docking plates 10 that match the snap-on plates 9 are installed on both sides of the rear of the main chassis 1 .
[0026] By mutually clamping the docking plate 10 and the clamping plate 9, multiple pipe jacking machines can be docked, thereby expanding the pipe jacking area.
[0027] The clamping plate 9 is arranged in a vertical L-shape, and the docking plate 10 is arranged in a vertical U-shape, and the thickness of one side of the U-shape of the docking plate 10 is greater than the thickness of the other side thereof.
[0028] The upper portion of the clamping plate 9 is open, and the bottom portion of the clamping plate 9 is not provided with an opening.
[0029] The upper and lower parts of the butt joint plate 10 are connected, and the butt joint plate 10 is inserted into the clamping plate 9 from top to bottom, thereby realizing the butt joint between the two pipe jacking machines.
[0030] A pipe jacking machine is used for municipal construction. During municipal construction, some pipes are squeezed and easily collapsed. In this case, a pipe jacking machine is needed. First, the entire pipe jacking machine is placed into the pipe. According to the direction of pipe collapse, the angle of the pipe jacking machine is adjusted so that the pipe jacking arc plate 3 can contact the collapsed area after the hydraulic rod 2 is driven. By rotating the rotating disk 6, the angle of the moving wheel 7 is adjusted so that it can move inward after fitting the pipe wall. Then, the moving wheel 7 is driven by the hydraulic cylinder 8 to fit the pipe wall.
[0031] The entire pipe jacking machine is moved by an external traction device to the collapsed area in the pipeline through the rolling of the moving wheel 7, and then the pipe jacking arc plate 3 is driven by the hydraulic rod 2 to contact the collapsed area. The pipe jacking arc plates 3 at both ends contact the pipe wall. As the hydraulic rod 2 is driven, the pipe jacking arc plates 3 in contact with the pipe wall of the collapsed area will lift the collapsed area, thereby realizing the pipe jacking operation.
[0032] When the collapse range is large, an appropriate number of pipe jacking machines can be selected for splicing. By docking the clamping plate 9 on the front of one pipe jacking machine main box 1 with the docking plate 10 on the rear of another pipe jacking machine main box 1, multiple pipe jacking machines can be spliced and used, so that multiple pipe jacking arc plates 3 can be used at the same time to lift the collapsed area of the pipe wall.

The preferred embodiments do not describe all details in detail, nor do they limit the present invention to the specific embodiments described. Obviously, many modifications and variations are possible based on the contents of this specification.
