Description

Technical Field

[0001] This application relates to the technical field of equipment for pipe jacking construction, and in particular to a pipe jacking angle adjustment device for pipe jacking construction. Background Technology

[0002] Pipe jacking is a method of underground pipeline construction, mainly used for the construction of underground pipelines, typically for tunnels, water supply, and power pipelines.

[0003] Pipe jacking construction is typically accomplished using a pipe jacking machine, which mainly consists of a hydraulic propulsion system and a rotary excavation system (commonly known as the jacking head). During construction, the jacking head cuts and excavates at the front, while the hydraulic propulsion system pushes the pipe into the tunnel from the rear, thus completing the pipe installation. The hydraulic propulsion system mainly includes a wall plate, hydraulic cylinders, and guide rails. The guide rails are laid horizontally on the ground, and the hydraulic cylinders are fixed to the wall plate against the wall. During construction, the pipe is placed on the guide rails, and the hydraulic cylinders apply force to the pipe to jack it up. The guide rails guide the movement of the pipe. For example, utility model patent CN220849675U discloses an auxiliary device for pipe jacking construction, which mainly includes hydraulic cylinders and guide rails. The hydraulic cylinders drive the pipe on the guide rails to move into the tunnel excavated by the jacking head.

[0004] As the volume of underground engineering projects increases, the construction environment also changes continuously. In some projects, the pipelines to be installed are at a certain angle to the horizontal plane (i.e., the terminal end of the pipeline is inclined downwards). For such special projects, the pipe jacking equipment in related technologies is not up to the task, so the construction of inclined pipelines is quite difficult. Utility Model Content

[0005] This application provides a pipe jacking angle adjustment device for pipe jacking construction, so as to reduce the difficulty for workers in the process of constructing non-horizontal pipelines.

[0006] The technical solution of the pipe jacking angle adjustment device for pipe jacking construction provided in this application is as follows:

[0007] A pipe jacking angle adjustment device for pipe jacking construction includes a backing plate fitted against the well wall, a hydraulic jacking device mounted on the backing plate, and a guide rail for guiding the movement of pipe sections. It also includes a horizontally positioned horizontal plate, with one end of the guide rail rotatably connected to the horizontal plate. The axis of rotation of the guide rail is perpendicular to its length. The end of the guide rail closest to its own axis is defined as the rotating end, and the end of the guide rail furthest from its own axis is defined as the movable end. A pad is provided below the movable end to support the movable end of the guide rail.

[0008] By adopting the above technical solution, during the construction of underground pipelines, pipe sections are placed on guide rails, which guide the movement of the pipe sections. Before construction, the guide rails can be rotated according to the angle of the pipeline, and then pads are used to support the guide rails from below, so that the guide rails are stably in an inclined state, which facilitates the guidance of the pipe sections by the rails, makes it easier for workers to handle different underground pipeline projects, and reduces the construction difficulty of inclined pipeline projects.

[0009] Optionally, the pad includes an abutment member, and the abutment member has an adjustment surface on its side facing away from the ground, the adjustment surface being set at an angle to the horizontal plane.

[0010] By adopting the above technical solution, the pad is placed under the track, and the adjustment surface is in contact with the track, which increases the contact area between the pad and the track and improves the stability of the pad in the process of supporting the track.

[0011] Optionally, multiple abutment members are provided, which are arranged in a direction parallel to the rotation axis of the guide rail and are connected to each other. The adjustment surfaces on the multiple abutment members have different angles.

[0012] By adopting the above technical solution, during the construction process, the sliding pads make different abutment parts correspond to the guide rail. Since the angles of the adjustment surfaces on the abutment parts are different, the guide rail can be stably in multiple states, thus expanding the applicable range of the angle adjustment device.

[0013] Optionally, the angles of the adjustment surfaces on the plurality of pads gradually increase in a direction parallel to the rotation axis of the guide rail.

[0014] By adopting the above technical solution, when the guide rail needs to be adjusted from a small angle to a large angle, it is only necessary to slide the pad in one direction, which improves construction efficiency.

[0015] Optionally, two pads are provided, and the two pads are respectively arranged on both sides of the guide rail along their own sliding direction.

[0016] By adopting the above technical solution, multiple pads support the guide rail, further improving the stability during the guide rail construction process.

[0017] Optionally, a guide ramp is provided between two adjacent abutment members, and the two sides of the guide ramp are respectively connected to the adjustment surfaces of the two adjacent abutment members.

[0018] By adopting the above technical solution, during the sliding process, the guide slope can be guided to rotate after it comes into contact with the guide rail, making it convenient for staff to adjust the position of the guide rail.

[0019] Optionally, the horizontal plate is provided with a drive assembly for moving the pad block. The drive assembly includes a drive screw and a drive member for rotating the drive screw. The drive screw is rotatably connected to the horizontal plate and threadedly connected to the pad block.

[0020] By adopting the above technical solution, the position of the pad can be adjusted by driving the screw to move the pad. At the same time, the self-locking property of the thread is used to block the movement of the pad, thereby improving the stability of the pad in supporting the guide rail.

[0025] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0026] This application discloses a pipe jacking angle adjustment device for pipe jacking construction.

[0027] Reference Figure 1 and Figure 2 A pipe jacking angle adjustment device for pipe jacking construction includes a backing plate 1, a horizontal plate 4, a hydraulic jacking device 2, and a guide rail 3. The horizontal plate 4 is horizontally positioned, while the backing plate 1 is vertically positioned and flush with the well wall. The hydraulic jacking device 2 is mounted on the backing plate 1 and is used to push the pipe section. One end of the guide rail 3 is rotatably connected to the horizontal plate 4. For ease of description, the end of the guide rail 3 closest to its own axis of rotation is defined as the rotating end, and the end furthest from its own axis is defined as the movable end. A pad 5 is provided on the horizontal plate 4 to support the movable end of the guide rail 3. The pad 5 is positioned below the movable end, and under the action of gravity, the movable end presses against the pad 5, allowing the guide rail 3 to form a certain angle with the horizontal plane. After the pipe section is placed on the guide rail 3, the axis of the pipe section is parallel to the length direction of the guide rail 3. The guide rail 3 guides the pipe section to move in a direction parallel to the guide rail 3, realizing the construction of inclined pipeline projects and reducing the difficulty of inclined pipeline construction.

[0028] Reference Figure 1 and Figure 2 The pad 5 includes an abutment 51, which has a block-shaped structure. An adjustment surface 52 is provided on the side of the abutment 51 facing away from the ground. The adjustment surface 52 is inclined upwards along a horizontal direction perpendicular to the axis of the guide rail 3, from the side closest to the axis of the guide rail 3 to the side furthest from the axis of the guide rail 3. (Combined) Figure 3 After the guide rail 3 is pressed onto the adjustment surface 52, the adjustment surface 52 can fit against the side of the guide rail 3 near the ground, which improves the stability of the support for the guide rail 3 and reduces the occurrence of deformation of the guide rail 3.

[0029] Reference Figure 1 and Figure 2 Multiple abutment members 51 are evenly spaced along the rotation axis of the guide rail 3; in this embodiment, four are used. The tilt angles (i.e., the angles between the adjustment surfaces 52 and the horizontal plane) on the multiple abutment members 51 are different. By using different abutment members 51 to support the guide rail 3, the guide rail 3 can be stably placed in multiple states, further facilitating the construction of pipeline projects with different angle settings.

[0030] Reference Figure 1 and Figure 2 The abutment 51 is slidably connected to the horizontal plate 4 along a direction parallel to the rotation axis of the guide rail 3. Multiple abutment pieces 51 are integrally formed with their sides close to each other. In actual operation, different abutment pieces 51 can be quickly aligned with the guide rail 3 by sliding pads 5, improving construction efficiency. The angles of the adjustment surfaces 52 on the multiple abutment pieces 51 along the rotation axis of the guide rail 3 gradually increase in a direction parallel to the rotation axis of the guide rail 3. In this embodiment, the angles of the adjustment surfaces 52 on the four pads 5 are 1°, 2°, 3°, and 4°, respectively, allowing the pads 5 to move back and forth randomly during the adjustment of the guide rail 3 angle, while reducing interference between the guide rail 3 and the abutment pieces after the guide rail 3 is positioned.

[0031] Reference Figure 1 and Figure 2To further improve the stability of the guide rail 3 during use, two pads 5 are provided corresponding to the guide rail 3, with the two pads 5 respectively located on both sides of the guide rail 3, supporting the guide rail 3 from both sides. A guide slope 53 is provided on the side of the abutment 51 that is perpendicular to the ground, and the guide slope 53 is inclined vertically upwards away from the guide rail 3. Moving the pad 5 towards the guide rail 3 allows the guide rail 3 to rotate under the action of the guide slope 53. The guide slope 53 is connected to the adjustment surfaces 52 of the two adjacent abutment 51, allowing the guide rail 3 to abut against different adjustment surfaces 52 by sliding the pads 5, facilitating the adjustment of the guide rail 3's angle. To facilitate the abutment between the guide rail 3 and the guide slope 53, a mating surface 54 is provided on the guide rail 3 corresponding to the guide slope 53. The mating surface 54 is inclined along the direction perpendicular to the length of the guide rail 3 from the side closer to the horizontal plate 4 to the side away from the horizontal plate 4 and towards the pad 5, so as to facilitate the rotation of the guide rail 3 by the guide slope 53.

[0032] Reference Figure 1 and Figure 2 A drive assembly 6 is also provided on the horizontal plate 4. The drive assembly 6 is used to drive the movement of the pads 5. The drive assembly 6 includes a drive screw 61 and a servo motor 62. The drive screw 61 is rotatably connected to the horizontal plate 4. The drive screw 61 has threads with opposite directions corresponding to the positions of the two pads 5. The two pads 5 are threadedly connected to the drive screw 61. Rotating the drive screw 61 can drive the two pads 5 to move closer or further apart. The drive component is used to drive the drive screw 61 to rotate. In this embodiment, the drive component is a servo motor 62. The housing of the servo motor 62 is fixedly connected to the horizontal plate 4, and the output shaft of the servo motor 62 is fixedly connected to the drive screw 61 to realize the drive of the drive screw 61.

[0033] Reference Figure 1 and Figure 2 The hydraulic jacking device 2 mainly includes a hydraulic cylinder 21 and a pressure equalizing ring 22. The pressure equalizing ring 22 has a circular structure with its axis parallel to the length direction of the track. The hydraulic cylinder 21 is located between the pressure equalizing ring 22 and the backing plate 1, with one end fixedly connected to the backing plate 1 and the other end connected to the pressure equalizing ring 22. Multiple hydraulic cylinders 21 are evenly spaced along the circumference of the pressure equalizing ring 22; in this embodiment, four are used. During the pipe section jacking process, the pressure equalizing ring 22 is in contact with the end face of the pipe section, and the hydraulic cylinder 21 pushes the pipe section to move. The pressure equalizing ring can be set on an inclined surface that is in contact with the end of the pipe section to improve the stability during the movement of the pipe section.

[0034] The implementation principle of the pipe jacking angle adjustment device for pipe jacking construction in this application embodiment is as follows: the track is rotatably connected to the horizontal plate 4, and the angle between the track length direction and the horizontal plane is changed by rotating the track, which makes it easier for workers to deal with the construction of different pipeline projects and reduces the construction difficulty of pipeline projects.

[0035] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
