Description

Technical Field

[0001] This utility model relates to the field of pipe jacking construction technology, and in particular to a pipe jacking support device. Background Technology

[0002] Pipe jacking is a trenchless construction method, a technology for laying pipelines with little or no excavation. In pipe jacking, the jacking equipment uses its jacking force to push the pipe into the ground at a designed slope within a working pit, and then the excavated soil is removed. After one section of pipe is pushed into the ground, the second section is lowered and the process continues. Support devices are needed to support the jacking pipe during construction.

[0003] When using existing pipe jacking construction support devices, their function is to support the pipe jacking during construction. However, the pipe jacking support devices are usually fixed in angle and do not have a structure for adjusting the angle of the pipe jacking. When it is necessary to adjust the docking angle of the pipe jacking, the position of the pipe jacking needs to be moved manually. This operation method is not only labor-intensive and inefficient, but also has certain dangers. Therefore, this utility model provides a pipe jacking support device. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that most existing pipe jacking support devices usually have a fixed angle and do not have a structure for adjusting the angle of the pipe jacking. When it is necessary to adjust the docking angle of the pipe jacking, the position of the pipe jacking needs to be moved manually. This operation method is not only labor-intensive and inefficient, but also has certain dangers. Therefore, a pipe jacking support device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pipe jacking support device, comprising a loading plate, four cylinders mounted on the surface of the loading plate, a support plate fixedly connected to the output ends of the four cylinders, and a rotating column rotatably connected to the surface of the support plate, a driven gear fixedly connected to the lower end of the rotating column, a driving gear meshing with the surface of the driven gear, a motor mounted on the lower surface of the driving gear, an arc-shaped support plate fixedly connected to the upper end of the rotating column, and limit components provided at both ends of the arc-shaped support plate.

[0006] Preferably, the limiting component includes a limiting plate, one side of which is fixedly connected to the side wall of the arc-shaped support plate, and a limiting groove is formed on the surface of the limiting plate. A bidirectional screw frame is rotatably connected to the inner wall of the limiting groove, and a limiting block is threadedly connected to the surface of the screw frame.

[0007] Preferably, the surface of the arc-shaped support plate is provided with multiple rotating grooves, and the inner walls of the multiple rotating grooves are rotatably connected to rolling wheels.

[0008] Preferably, the lower surface of the loading plate is equipped with four casters, and one end of the loading plate is fixedly connected to a pusher.

[0009] Preferably, movable rods are fixedly connected to both sides of the loading plate, and a fixed plate is rotatably connected to the lower end of the movable rods. Multiple conical columns are slidably connected to the surface of the fixed plate.

[0010] In summary, this application includes the following beneficial technical effects:

[0011] 1. In this utility model, the pipe on the arc-shaped support plate is moved by the output end of the cylinder, which can adjust the height of the pipe. When it is necessary to adjust the pipe docking angle, the motor can be turned on, and the output end of the motor can drive the driving gear and the driven gear to rotate. The driven gear drives the arc-shaped support plate on the rotating column to rotate, which makes it convenient for the staff to adjust the pipe docking angle and improves work efficiency.

[0012] 2. In this utility model, by rotating the bidirectional screw frame, the limiting blocks on the surface of the bidirectional screw frame approach each other with the help of the threads. When the limiting blocks are pressed against the surface of the pipe, pipes of different diameters can be limited and fixed. The rolling wheels on the surface of the arc-shaped support plate can reduce the friction between the pipe and the surface of the arc-shaped support plate, avoid damage to the outer wall of the pipe during the pipe jacking process, and also facilitate the workers to adjust the position of the pipe on the arc-shaped support plate.

Detailed Implementation

[0017] Reference Figure 1-3As shown, this utility model provides a technical solution: a pipe jacking support device, including a loading plate 1, four cylinders 2 mounted on the surface of the loading plate 1, a support plate 3 fixedly connected to the output ends of the four cylinders 2, and a rotating column 4 rotatably connected to the surface of the support plate 3. A driven gear 5 is fixedly connected to the lower end of the rotating column 4, and a driving gear 6 is meshed with the surface of the driven gear 5. A motor 7 is mounted on the lower surface of the driving gear 6. An arc-shaped support plate 8 is fixedly connected to the upper end of the rotating column 4, and limit components are provided at both ends of the arc-shaped support plate 8. The pipe is placed on the surface of the arc-shaped support plate 8, and the two ends of the pipe are fixed and limited by the limit components. The pipe on the arc-shaped support plate 8 is moved by the output ends of the cylinders 2 to adjust the height of the pipe. When it is necessary to adjust the docking angle of the pipe, the motor 7 can be turned on. The output end of the motor 7 drives the driving gear 6 and the driven gear 5 to rotate, and the driven gear 5 drives the arc-shaped support plate 8 on the rotating column 4 to rotate, thereby facilitating the adjustment of the pipe docking angle by the workers and improving work efficiency.

[0018] Reference Figure 1 and Figure 3 As shown in this embodiment: the limiting component includes a limiting plate 11, one side of which is fixedly connected to the side wall of the arc-shaped support plate 8, and a limiting groove 12 is formed on the surface of the limiting plate 11. A bidirectional screw frame 13 is rotatably connected to the inner wall of the limiting groove 12, and a limiting block 14 is threadedly connected to the surface of the screw frame. When the pipe is placed on the surface of the arc-shaped support plate 8, the bidirectional screw frame 13 is rotated, and the limiting blocks 14 on the surface of the bidirectional screw frame 13 approach each other by means of the threads. When the limiting blocks 14 are pressed against the surface of the pipe, pipes of different diameters can be limited and fixed. A plurality of rotating grooves 9 are formed on the surface of the arc-shaped support plate 8, and a rolling wheel 10 is rotatably connected to the inner wall of the plurality of rotating grooves 9. By setting the rolling wheel 10, the friction between the pipe and the surface of the arc-shaped support plate 8 can be reduced, avoiding damage to the outer wall of the pipe during the pipe jacking process, and also making it convenient for the staff to adjust the position of the pipe on the arc-shaped support plate 8.

[0019] Reference Figure 1 and Figure 2 As shown, specifically, four casters 15 are installed on the lower surface of the loading plate 1, and a pusher 16 is fixedly connected to one end of the loading plate 1. By setting the casters 15 and the pusher 16, the loading plate 1 can be pushed to the designated position by the casters 15. When the casters 15 are rolling, the pusher 16 can better control the trajectory of the casters 15. Movable rods 17 are fixedly connected to both sides of the loading plate 1. The lower end of the movable rods 17 is rotatably connected to a fixed plate 18, and multiple conical columns 19 are slidably connected to the surface of the fixed plate 18. When the loading plate 1 reaches the designated position, the movable rods 17 can be rotated to make the fixed plate 18 parallel to the ground, and then the conical columns 19 can be inserted into the ground to fix the loading plate 1 and enhance the stability during pipe jacking construction.

[0020] The working principle is as follows: the pipe is placed on the surface of the arc-shaped support plate 8. By rotating the bidirectional screw frame 13, the limiting blocks 14 on the surface of the bidirectional screw frame 13 approach each other through the threads. When the limiting blocks 14 press against the surface of the pipe, the pipe is fixed. Then, the pusher 16 pushes the universal wheel 15 to push the pipe to the designated position. Then, the movable rod frame 17 is rotated to make the fixing plate 18 parallel to the ground. Then, the cone column 19 is inserted into the ground to fix the loading plate 1, thereby enhancing the stability during pipe jacking construction. Then, the output end of the cylinder 2 drives the pipe on the arc-shaped support plate 8 to move, which can adjust the height of the pipe. When it is necessary to adjust the pipe docking angle, the motor 7 can be turned on. The output end of the motor 7 drives the drive gear 6 and the driven gear 5 to rotate. The driven gear 5 drives the arc-shaped support plate 8 on the rotating column 4 to rotate, thereby facilitating the adjustment of the pipe docking angle by the workers and improving work efficiency.
