Description

Technical Field

[0001] The utility model relates to the technical field of pipe jacking construction, in particular to an auxiliary device for pipe jacking construction. Background Art

[0002] Pipe jacking involves using the jacking force generated by jacking equipment to push the pipe into the soil according to the designed slope within the working pit and remove the soil. After one section of pipe is pushed into the soil, the second section is lowered and pushed in again.

[0003] The current auxiliary guide device for pipe jacking construction, as described in the patent with announcement number CN220688213U, includes a base and a driving mechanism for pushing the pipe to move. Two guide plates and an angle adjustment mechanism for adjusting the angle of the guide plates are hinged on the base. The two guide plates are arranged in a V shape. The top wall of the base is provided with a first mounting groove which is recessed downward. A locking block which is slidably connected up and down is provided in the first mounting groove. An elastic member for pushing the locking block is provided in the first mounting groove. The locking block includes a guide surface facing the driving mechanism and a locking surface facing away from the driving mechanism. When the pipe jacking is installed, the driving mechanism pushes the pipe to abut against the guide surface, causing the locking block to move downward and compress the elastic member. After the pipe jacking is installed, the elastic member pushes the locking block upward to abut against the end wall of the pipe jacking. Compared with the prior art method of using a jack to push a T-shaped steel plate to abut against the end wall of the pipe, the present invention improves the construction efficiency of the pipe jacking.

[0004] Regarding the above-mentioned related technologies, the inventor believes that the guide plate in the device is supported by only one support rod when in use, and the support strength is limited. When the weight of the jacking pipe is too heavy, the support rod is prone to breakage, thereby affecting construction efficiency. Utility Model Content

[0005] The purpose of the utility model is to provide an auxiliary device for pipe jacking construction to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] An auxiliary device for pipe jacking construction includes a base, a first mounting groove is opened in the vertical direction on the top of the base, and a plurality of bidirectional screws distributed in a linear array are rotatably connected in the first mounting groove, and one end of each bidirectional screw located on the same side extends to the outside of the base and is commonly connected to a driving unit, and a movable seat is commonly threadedly connected on the threaded surfaces on both sides of each bidirectional screw, and a support block is fixedly connected to the top of the movable seat, and guide slopes are provided on opposite sides of the two support blocks, and a second mounting groove is opened on the guide slope, and a plurality of guide rollers arranged parallel to the guide slope are rotatably connected in the second mounting groove, and an L-shaped fixing frame is fixedly connected to one side of the base, and a pushing assembly is provided on the L-shaped fixing frame.

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] See also Figure 1-4An auxiliary device for pipe jacking construction includes a base 1, a first mounting slot 2 is provided on the top of the base 1 in the vertical direction, and a plurality of bidirectional screws 3 distributed in a linear array are rotatably connected in the first mounting slot 2. By providing a plurality of bidirectional screws 3, when the pipe jack is placed between two support blocks 6, the movable seat 5 is more stable and will not deviate to the sides, thereby reducing the possibility of damage to the surface threads of the bidirectional screws 3. One end of each bidirectional screw 3 located on the same side extends to the outside of the base 1 and is commonly connected to a driving unit 4. The movable seat 5 is commonly threadedly connected on the threaded surfaces on both sides of each bidirectional screw 3. A support block 6 is fixedly connected to the top of the movable seat 5. A guide bevel 7 is provided on the opposite sides of the two support blocks 6. A second mounting slot is provided on the guide bevel 7. A plurality of guide rollers 8 arranged parallel to the guide bevel 7 are rotatably connected in the second mounting slot. An L-shaped fixing frame 9 is fixedly connected to one side of the base 1, and a jacking assembly 10 is provided on the L-shaped fixing frame 9. When carrying out pipe jacking construction, the device is first adjusted according to the diameter of the pipe jacking so that the device can be applied to pipe jacking construction of different diameters. During adjustment, the driving unit 4 drives the bidirectional screws 3 to rotate synchronously, thereby driving the movable seats 5 on both sides to drive the two support blocks 6 to move relative or oppositely, so that they are adapted to the pipe jacking and are convenient for placing the pipe jacking. After the adjustment is completed, the pipe jacking can be placed between the two support blocks 6. Under the action of the guide slopes 7 on both sides, the pipe jacking will be automatically centered, thereby guiding the pipe jacking. Finally, the pipe jacking can be pushed into the soil by the pushing assembly 10. The guide rollers 8 provided can avoid friction between the pipe jacking and the guide slopes 7, which facilitates the pushing assembly 10 to push the pipe jacking to move while avoiding wear on the pipe jacking. The above structure makes the device suitable for pipe jacking construction of different diameters while having a strong supporting effect.

[0022] Furthermore, a support plate 11 arranged along the length direction of the base 1 is fixedly connected in the first mounting groove 2, and a through groove corresponding to each bidirectional screw 3 is opened at the bottom of the support plate 11. By providing the support plate 11, it is possible to prevent the bottom of the top pipe from pressing on the bidirectional screw 3 when the top pipe is placed between the two support blocks 6, thereby protecting the bidirectional screw 3.

[0023] Furthermore, the drive unit 4 includes a first gear 401 fixedly connected to one end of the bidirectional lead screw 3, a second gear 402 rotatably arranged between two adjacent first gears 401, and the second gear 402 is simultaneously engaged with the first gears 401 on both sides. A drive motor 403 is fixedly connected to one side of the base 1 through a bracket, and the output end of the drive motor 403 is connected to one of the first gears 401. When the drive unit 4 is in use, by starting the drive motor 403, one of the first gears 401 is driven to rotate. With the cooperation of the second gears 402, the other first gears 401 will rotate synchronously, thereby driving the bidirectional lead screws 3 to rotate synchronously.

[0024] Furthermore, a protective shell 12 is detachably provided on one side of the base 1 by bolts, and the drive unit 4 is arranged inside the protective shell 12. The protective shell 12 can protect the drive unit 4 and prevent the drive unit 4 from malfunctioning due to external factors during construction, resulting in inability to use.

[0025] Furthermore, the pushing assembly 10 includes a plurality of driving cylinders 1001 fixedly connected to the L-shaped fixing frame 9, and a pushing plate 1002 is fixedly connected to the output end of each driving cylinder 1001. A flexible pad 1003 is provided on one side of the pushing plate 1002 for pushing. The material of the flexible pad 1003 is rubber. When the pushing assembly 10 is in use, by starting the driving cylinder 1001, its telescopic end pair drives the pushing plate 1002 toward the jacking pipe, and then pushes the jacking pipe into the soil. By providing multiple driving cylinders 1001, the jacking pipe can be pushed more stably and with more power. The provision of the flexible pad 1003 can have a buffering effect, preventing the pushing plate 1002 from damaging the jacking pipe when the jacking pipe is pushed into the soil.

[0026] When in use, when carrying out jacking construction, the device is first adjusted according to the diameter of the jacking pipe so that the device can be suitable for jacking construction of different diameters. During adjustment, the driving unit 4 drives the two-way screws 3 to rotate synchronously, thereby driving the moving seats 5 on both sides to drive the two support blocks 6 to move relative or oppositely, so that they are adapted to the diameter of the jacking pipe. After the adjustment is completed, the jacking pipe can be placed between the two support blocks 6. Under the action of the guide slopes 7 on both sides, the jacking pipe will be automatically centered, thereby guiding the jacking pipe. Finally, the jacking pipe can be pushed into the soil by the pushing assembly 10. The guide roller 8 provided can avoid friction between the jacking pipe and the guide slope 7 while facilitating the pushing assembly 10 to push the jacking pipe to move. Through the above structure, the device can be suitable for jacking construction of different diameters while having a strong supporting effect.
