Description

Technical Field

[0001] This utility model relates to the field of pipe jacking construction equipment technology, and in particular to a long-distance pipe jacking construction equipment for urban underground utility tunnels. Background Technology

[0002] Urban underground utility tunnels are structures and ancillary facilities built underground in cities to accommodate two or more types of urban engineering pipelines. During the construction of long-distance utility tunnels, pipe jacking equipment is usually required to excavate the soil and push the pipe sections to the designated location.

[0003] When using existing pipe jacking equipment, the equalizing ring component usually needs to be fitted to the inner wall of the pipe to ensure uniform stress on the pipe and stability during subsequent pushing operations. However, since the specifications of the equalizing ring component are fixed, it cannot achieve a perfect fit when facing pipes of different widths, resulting in poor adaptability. Furthermore, since the equalizing ring is fixed by bolts, its overall assembly and disassembly are quite cumbersome. Therefore, to solve this problem, designing a long-distance pipe jacking construction equipment for urban underground utility tunnels is something we need to consider. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a long-distance pipe jacking construction device for urban underground utility tunnels. In terms of usage, it is equipped with a pipe jacking mechanism, which enables long-distance pipe jacking operations. Furthermore, by controlling the movement of two limit columns driven by a motor, the pressure equalizing ring can be easily replaced according to the width of the pipe, demonstrating good adaptability. It is also equipped with an auxiliary support mechanism, which effectively improves the convenience of replacement operations.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A long-distance pipe jacking construction device for urban underground utility tunnels includes a base with a support plate fixedly connected to its rear end; a pipe jacking mechanism including two first telescopic rods installed on the front side of the support plate, the telescopic ends of the two first telescopic rods being fixedly connected to a pipe jacking plate; a pressure equalizing ring provided on the front side of the pipe jacking plate; a rectangular inner groove formed on the front side of the pipe jacking plate; a bidirectional threaded rod rotatably connected between the inner walls of the left and right sides of the rectangular inner groove; a motor installed on the right side of the pipe jacking plate; the right end of the bidirectional threaded rod penetrating the right inner wall of the rectangular inner groove and fixedly connected to the output shaft of the motor; a slider threadedly connected to each of the two threaded ends of the bidirectional threaded rod; and limit posts fixedly connected to the opposite sides of the two sliders; and an auxiliary support mechanism for assisting in replacing the pressure equalizing ring.

[0007] Preferably, the equalizing ring has horizontally formed cylindrical limiting grooves on the inner walls of both the left and right sides, and the two limiting columns are slidably connected to the inner walls of the corresponding limiting grooves.

[0008] Preferably, both of the first telescopic rods are hydraulic telescopic rods, and the two threaded ends of the bidirectional threaded rod have opposite thread directions.

[0009] Preferably, the motor is a servo motor that can change the direction of rotation, and both sliders are slidably connected to the inner wall of the rectangular inner groove.

[0010] Preferably, the auxiliary support mechanism includes two second telescopic rods installed on the upper end of the base, and the telescopic ends of the two second telescopic rods are fixedly connected to a support block, and the upper end of the support block is provided with an arc-shaped groove.

[0011] Preferably, both second telescopic rods are electrically operated telescopic rods, and the support block cooperates with the pressure equalizing ring.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] A pipe jacking mechanism is installed. By controlling two first telescopic rods, the pipe jacking plate and the equalizing ring are moved forward, enabling long-distance pipe jacking operations. At the same time, a starter motor drives two sliders and two limit posts to move synchronously. With the help of two cylindrical limit grooves, the equalizing ring can be replaced conveniently and quickly, thus meeting the needs of pushing operations on pipes of different widths and ensuring the actual efficiency of pipe jacking construction. The overall adaptability is good. An auxiliary support mechanism is also set up. By controlling two second telescopic rods to move the support block upward, the bottom of the equalizing ring can be supported, which effectively improves the convenience of replacing the equalizing ring.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-4 A long-distance pipe jacking construction device for urban underground pipe corridors includes a base 1, and a support plate 2 is fixedly connected to the rear end of the base 1.

[0021] The pipe jacking mechanism includes two first telescopic rods 3 installed on the front side of the support plate 2. Both first telescopic rods 3 are hydraulic telescopic rods. The telescopic ends of the two first telescopic rods 3 are fixedly connected to the pipe jacking plate 4. A pressure equalizing ring 5 is provided on the front side of the pipe jacking plate 4. During pipe jacking operations, the pressure equalizing ring 5 will fit against the inner wall of the pipe to ensure uniform stress on the pipe and stability when the pipe is pushed. Horizontal cylindrical limiting grooves 11 are opened on the inner walls of the left and right sides of the pressure equalizing ring 5. A rectangular inner groove 6 is opened on the front side of the pipe jacking plate 4. A bidirectional threaded rod 7 is rotatably connected between the inner walls of the left and right sides of the rectangular inner groove 6. The threads at the two ends of the threaded rod are opposite in direction. A motor 8 is installed on the right side of the top pipe plate 4. The motor 8 is a servo motor that can change the direction of rotation. The right end of the bidirectional threaded rod 7 passes through the right inner wall of the rectangular inner groove 6 and is fixedly connected to the output shaft of the motor 8. A slider 9 is threadedly connected to both threaded ends of the bidirectional threaded rod 7. Both sliders 9 are slidably connected to the inner wall of the rectangular inner groove 6. Limiting posts 10 are fixedly connected to the opposite sides of the two sliders 9. Both limiting posts 10 are slidably connected to the inner wall of the corresponding limiting groove 11. By controlling the two limiting posts 10 to be inserted into the corresponding limiting groove 11, the pressure equalization ring 5 can be conveniently limited.

[0022] An auxiliary support mechanism is used to assist in replacing the equalizing ring 5. The auxiliary support mechanism includes two second telescopic rods 12 installed on the upper end of the base 1. Both second telescopic rods 12 are electric telescopic rods. The telescopic ends of the two second telescopic rods 12 are fixedly connected to a support block 13. The support block 13 cooperates with the equalizing ring 5. By controlling the upward movement of the support block 13, the equalizing ring 5 can be supported, which facilitates the subsequent replacement of the equalizing ring 5 by the staff and reduces the workload of the staff. An arc groove 14 is opened at the upper end of the support block 13.

[0023] In this utility model, during use, the pipeline is first moved to the designated pushing position, and then the two first telescopic rods 3 are controlled to drive the jacking plate 4 and the pressure equalizing ring 5 to move forward synchronously. During the movement, the pressure equalizing ring 5 will be inserted into the inside of the pipeline and fit against its inner wall, and then the pipeline will be pushed forward. After the pipeline is moved into place, the jacking plate 4 and the pressure equalizing ring 5 are controlled to move backward to the initial position. Then another pipeline is moved to the designated pushing position and the pushing operation is carried out. When the latter pipeline is pushed, it will push the former pipeline to move towards a deeper layer. This cycle can realize long-distance pipe jacking construction operation.

[0024] When the specifications of the equalizing ring 5 need to be adjusted according to the width of the pipeline, first, control the jacking plate 4 to move to the rearmost end, and control the two second telescopic rods 12 to drive the support block 13 to move upward, so that the arc-shaped groove 14 at the upper end of the support block 13 abuts against the lower end of the equalizing ring 5, thereby supporting the bottom of the equalizing ring 5 and improving the convenience of subsequent replacement of the equalizing ring 5 by the staff. Then, start the motor 8 to drive the bidirectional threaded rod 7 to rotate, driving the two sliders 9 and the two limit posts 10 to move synchronously towards each other, so that the two limit posts 10 completely disengage from the corresponding cylindrical limit grooves 11, thus releasing the equalizing ring. When the pressure equalizing ring 5 is at its limit, it can be replaced. After replacement, align the two cylindrical limit grooves 11 on the new pressure equalizing ring 5 with the corresponding limit posts 10 (during this process, the support block 13 can be controlled to move the new pressure equalizing ring 5 up and down according to the actual situation to improve the alignment efficiency). Then, control the motor 8 to drive the two limit posts 10 to insert into the corresponding cylindrical limit grooves 11 to realize the installation of the new pressure equalizing ring 5. The whole replacement process is relatively convenient, and the specifications of the pressure equalizing ring 5 can be quickly adjusted according to the width of the pipeline. The overall adaptability is good, ensuring the working efficiency of pipe jacking construction.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
