Specific embodiments

[0020] As Figure 1-2 shown, a pipe jacking angle adjustment device for pipe jacking construction includes a top plate 1 and a connecting plate 2. The connecting plate 2 is arranged below the top plate 1. It further includes a hydraulic rod 3, an adjusting component and a positioning component. The hydraulic rod 3 is fixedly connected to the bottom of the top plate 1, and the hydraulic rods 3 are symmetrically distributed in pairs. The connecting plate 2 is movably connected to the free end of the hydraulic rod 3 through a universal joint. The adjusting component is arranged at the bottom of the connecting plate 2, and the positioning component is arranged below the adjusting component.

[0021] As Figure 1-4 shown, in order to simply, efficiently and stably adjust the pipe jacking angle appropriately, the adjusting component includes a central shaft 4, a worm gear 5, a worm 6, a side plate 7, an electric push rod 8, a vertical plate 9 and an inserting post 10. The central shaft 4 penetrates through the connecting plate 2 and is rotatably connected thereto. The worm gear 5 is fixedly connected to the central shaft 4. A servo motor 11 is fixedly installed at the bottom of the connecting plate 2. The worm 6 is fixedly connected to the output end of the servo motor 11. The worm 6 and the worm gear 5 are meshed with each other. The side plate 7 is fixedly connected to one end of the worm 6. A mounting plate 12 is fixedly connected to the bottom of the connecting plate 2. The electric push rod 8 penetrates through the mounting plate 12 and is fixedly connected thereto. The vertical plate 9 is fixedly connected to the free end of the electric push rod 8. The inserting post 10 is fixedly connected to the outer side wall of the vertical plate 9. The inserting posts 10 are symmetrically arranged. A positioning groove 13 is arranged on the outer side wall of the side plate 7. The positioning grooves 13 are arranged in an annular distribution. The inserting post 10 and the positioning groove 13 are adapted to each other. The upper end of the central shaft 4 is fixedly connected with a disc 21. The top of the connecting plate 2 is fixedly connected with an annular plate 22. The top of the annular plate 22 is recessed. The bottom of the disc 21 is provided with balls 23. The bottoms of the balls 23 roll on the top of the annular plate 22.

[0022] As Figure 1-4As shown in the figure, in order to conveniently and quickly clamp and position the outer wall of the jacking pipe, the positioning assembly includes a cross plate 14, connecting columns 15, a bottom plate 16, a placement block 17, a cylinder 18, a pressing block 19, and a slider 20. The cross plate 14 is fixedly connected to the lower end of the central shaft 4, and the connecting columns 15 are fixedly connected to the bottom of the cross plate 14. The connecting columns 15 are symmetrically distributed.
