[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments: A pipe jacking machine for water conservancy pipeline construction includes a pit bottom and a pit wall. The pit wall and the pit bottom are respectively fixedly connected to both sides of a support. The two sides of the support are respectively slidably connected to a first jacking mechanism and a second jacking mechanism. The first jacking mechanism is driven by a first jacking cylinder, and the second jacking mechanism is driven by a second jacking cylinder. The movable end of the first jacking mechanism is fixedly connected to the fixed end of the second jacking mechanism. The movable end of the second jacking mechanism is used to push the pipe to move. The pipe is placed on a base, and the base is fixed to the pit bottom. Limiting guide components are provided on both sides of the support corresponding to the arc-shaped wall surface of the pipe for limiting and guiding the pipe.

[0013] In this embodiment, the limiting guide component provides support and guidance for the pipe. Driven by the second ejection cylinder, the second ejection mechanism can stably push the pipe along a straight track, ensuring the accuracy and efficiency of the construction.

[0014] The limiting guide assembly includes a screw, one end of which is rotatably connected to the base. The screw is screwed to the lower part of a bent rod, and the lower side of the bent rod is slidably connected to a linear track. One end of the linear track is fixedly connected to the base. The bent rod is L-shaped and has a groove on the other side. One end of the bent rod is rotatably connected to a connecting block, which is fixed to the lower part of one side of a support plate. A set of evenly arranged ball grooves is fixedly provided on the other side of the support plate, and a universal ball is rolled in each ball groove. One end of a straight groove rod is fixedly connected to the lower middle part of one side of the support plate. A bolt passes through the slide of the straight groove rod and the groove on the bent rod, and the bolt is screwed to a nut.

[0015] In this embodiment, the rotation of the screw can drive the bending rod to slide along the straight track, thereby adjusting the position of the support plate. The combination of ball groove and universal ball on the support plate allows the support plate to flexibly adapt to the curved wall surface of the pipe when in contact with it, providing stable support and guidance. The cooperation of the straight groove rod, bolt and nut further enhances the stability and adjustability of the structure. When adjustment is needed, loosen the nut to make the screw rotate, so that the bolt moves along the slide of the straight groove rod to the appropriate position, and then tighten the nut to fix the position of the support plate. The operation is simple and the adjustment range is large, which can meet the construction needs of pipes of different specifications.

[0016] The other end of the screw is fixedly connected to a rotating wheel. Rotating the rotating wheel drives the screw to rotate, making it easy to use.

[0017] The movable ends of the first ejection mechanism and the second ejection mechanism are respectively slidably connected to both sides of the support.

[0018] In this embodiment, the sliding connection between the movable ends of the first ejection mechanism and the second ejection mechanism and the two sides of the support ensures the stability and straightness of the ejection mechanism during the process of pushing the tube to move, and avoids construction errors caused by deviation. In actual construction, the operator only needs to control the operation of the first ejection cylinder and the second ejection cylinder to achieve accurate tube ejection.

[0019] The other end of the linear track is fixedly connected to a bracket, which increases stability.

[0020] The method of using this utility model is as follows: In actual operation, firstly, place the pipe to be laid on the base, ensuring that the position of the pipe corresponds to the movable end of the second ejection mechanism. At the same time, adjust the position of the limiting guide component. By rotating the wheel, the screw is driven to rotate, thereby causing the bending rod to slide along the straight track. Adjust the support plate to a suitable position so that the universal ball on the support plate can closely fit the arc-shaped wall of the pipe, providing stable support and guidance for the pipe. Then, start the first ejection cylinder and the second ejection cylinder. The first ejection cylinder drives the first ejection mechanism. The movable end of the first ejection mechanism drives the fixed end of the second ejection mechanism. The second ejection cylinder drives the second ejection mechanism. The movable end of the second ejection mechanism pushes the pipe to move along the predetermined direction. During the pushing process, the limiting guide component always limits and guides the pipe, ensuring the accuracy and straightness of the pipe movement, until the pipe is accurately pushed into the designated position, completing the pipe laying work.

[0021] The above-disclosed embodiments are merely specific examples of this utility model. However, this utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
