Description

Technical Field

[0001] This utility model relates to the field of pipe jacking machines, and in particular to a pipe jacking machine for municipal construction. Background Technology

[0002] Pipe jacking machines are used for laying underground pipelines and have significant advantages in municipal construction. They use the thrust of the jacking equipment to push the pipeline into the soil according to the design without excavating the ground. Pipe jacking machines are chosen for municipal construction mainly because they have a small environmental impact, reduce road and ecological damage, minimize interference with traffic, commerce and residents' lives, have high construction efficiency, can excavate quickly and can operate multiple working pits in parallel, and ensure construction quality. They use advanced guidance and measurement equipment to precisely control pipeline laying, and the support and sealing system ensures soil stability and pipeline interface sealing. They can also adapt to complex geological conditions. Different types of pipe jacking machines can handle various strata such as soft soil, sand, and rock, as well as special geological problems.

[0003] Common types of pipe jacking machines used in municipal construction include slurry balance, earth pressure balance, and rock pipe jacking machines. Slurry balance pipe jacking machines inject slurry into the tunnel face to form a mud film, balancing water and soil pressure. The cut soil and slurry are mixed and circulated to the ground for separation and treatment before being circulated again. Earth pressure balance pipe jacking machines rely on the cutterhead to cut soil into the soil chamber, and the screw conveyor is used to adjust the pressure in the soil chamber to balance the pressure at the tunnel face. Rock pipe jacking machines are equipped with high-strength cutters. When the cutterhead rotates, the cutters squeeze and cut the rock, and the broken rock is discharged through the conveying equipment, thus enabling the laying of underground pipelines under different geological conditions.

[0004] In municipal construction, pipe jacking machines play a crucial role in laying pipelines. However, in actual use, pipe jacking machines used in municipal construction have revealed a problem that urgently needs to be solved: the pipe sizes involved in different projects vary greatly, but existing pipe jacking machines are often only compatible with pipes of specific specifications. Once a pipe of a different size is encountered, the construction team has to interrupt the work and spend a lot of time and manpower to replace the equipment with a suitable one. This frequent equipment replacement not only seriously disrupts the construction rhythm but also greatly affects the efficiency that pipe jacking machines should have, and significantly delays the overall progress of municipal projects. Utility Model Content

[0010] As a further description of the above technical solution:

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the required pipe is first selected according to the needs, and one end of it is connected to the motor. At this time, the fixing ring is pulled outward, the pipe is placed in the middle of the fixing ring, and then the fixing ring is released, so that it contracts inward under the action of the spring, and its inner wall fits against the outer wall of the pipe, thus fixing the pipe.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3 The present invention provides an embodiment of a pipe jacking machine for municipal construction, comprising a fixed plate 1, a slide rail 4 fixedly connected to the top of the fixed plate 1 for limiting the movement direction of a sliding block 5, a sliding block 5 slidably connected to the outer wall of the slide rail 4 for moving a pipe 7, a pushing component provided on the top of the fixed plate 1 for pushing the pipe 7, a motor 6 fixedly connected to the top of the sliding block 5 for providing power for rotating the pipe 7, a pipe 7 fixedly connected to the output end of the motor 6, a laying body, and a plurality of fixed rods 8 fixedly connected to the top of the sliding block 5 for fixing connecting blocks 9, a connecting block 9 fixedly connected to one side of each fixed rod 8 for connecting a fixing component, and a fixing component provided inside each connecting block 9 for fixing the height of the pipe 7;

[0034] Each fixing component includes an extension rod 10, a limiting plate 11, a spring 12, and a fixing ring 13. The outer wall of each extension rod 10 is slidably connected to the inside of the connecting block 9 to drive the fixing ring 13 to move. The inner wall of each limiting plate 11 is fixedly connected to the outer wall of the extension rod 10 to restrict the movement of the extension rod 10. Each spring 12 is disposed inside the connecting block 9 to provide elastic force to the extension rod 10. One end of each spring 12 is fixedly connected to one side of the fixing rod 8, and the other end of each spring 12 is fixedly connected to one end of the extension rod 10. One side of each fixing ring 13 is fixedly connected to one end of the extension rod 10 to fix the pipe 7. The pushing component includes a connecting plate 2 and multiple telescopic rods 3. The bottom of the connecting plate 2 is fixedly connected to the top of the fixing plate 1 to connect the telescopic rods 3. One end of each telescopic rod 3 is fixedly connected to one side of the connecting plate 2 to push the sliding block 5 to move, and the other end of each telescopic rod 3 is fixedly connected to one side of the sliding block 5.

[0035] Specifically, during pipe jacking operations in municipal construction, the first step is to select a suitable pipe 7 based on the actual needs of the project. After selecting the pipe 7, connect one end of it to the motor 6. Next, operate the fixing ring 13, firmly grasp both sides of the fixing ring 13 with both hands, and slowly pull it outward. Then, place the pipe 7 in the middle gap formed by the fixing ring 13. After the pipe 7 is accurately positioned, slowly release your hands. Under the strong action of the highly elastic spring 12, the fixing ring 13 quickly contracts inward until its inner wall tightly fits the outer wall of the pipe 7, thus firmly fixing the pipe 7 and laying a solid foundation for subsequent construction.

[0036] Reference Figure 4 and Figure 5 Multiple support columns 14 are slidably connected inside the fixed plate 1 to support the equipment. Each support column 14 has multiple connecting grooves 15 on one side to accommodate fixed columns 17. Each support column 14 has a support foot 16 fixedly connected to its bottom end to support the equipment. The support columns 14 are arranged in a symmetrical array and slidably connected inside the fixed plate 1. Multiple fixed columns 17 are slidably connected inside the fixed plate 1 to control the height of the support columns 14. Multiple sliding columns 18 are fixedly connected to the outer wall of each fixed column 17 to limit the range of movement of the fixed column 17. A connecting column 19 is fixedly connected to one end of each fixed column 17 to connect a pull ring 20. A pull ring 20 is rotatably connected inside each connecting column 19 to pull the fixed column 17. The fixed columns 17 are arranged in a parallel array and slidably connected inside the fixed plate 1. One end of each fixed column 17 is slidably connected inside the connecting groove 15. The sliding columns 18 are arranged in a symmetrical array and fixedly connected to the outer wall of the fixed column 17. The outer wall of each sliding column 18 is slidably connected inside the fixed plate 1.

[0037] Specifically, in the working environment of municipal construction, uneven ground is often encountered. At this time, the construction worker holds the pull ring 20 and then pulls the pull ring 20 outward. With this action, the state in which the fixed column 17 was originally tightly embedded in the connecting groove 15 is broken, and the two gradually separate, thus unlocking the support column 14. Subsequently, the construction worker adjusts the height of the support column 14 according to the actual ground conditions on site until the precise height required by the project is reached. When the height is adjusted to the correct position, the construction worker holds the pull ring 20 again and pushes it back. During this process, the fixed column 17 slides into the corresponding connecting groove 15. In this way, the height of the support foot 16 is firmly fixed, providing a solid guarantee for the stable operation of the pipe jacking machine on uneven ground.

[0038] Working principle: When using a pipe jacking machine for municipal construction, if the ground is uneven and the support foot 16 needs to be adjusted, first hold the pull ring 20 and pull it outwards to disengage the fixing column 17 from the connecting groove 15, unlock the support column 14, and then adjust the height of the support column 14 to the required height. Then push the pull ring 20 back to allow the fixing column 17 to enter the corresponding connecting groove 15, thereby fixing the height of the support foot 16. Then, select the pipe 7 to be used according to the requirements and connect one end of it to the motor 6. At this time, pull the fixing ring 13 outwards and place the pipe 7 in the middle of the fixing ring 13. Then, release the fixing ring 13 so that it retracts inwards under the action of the spring 12, and its inner wall fits against the outer wall of the pipe 7, fixing the pipe 7. After that, start the telescopic rod 3 and the motor 6 to start the laying of the pipe 7.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
