[0021] As Figure 1-2 shown, a hydraulic jacking structure for a rectangular pipe jacking includes a frame 1 and an insertion post 2. There are four groups of frames 1 which are combined into a square box, and the insertion post 2 is fixedly connected to the outer side wall of the frame 1. It further includes a splicing and positioning component which is arranged inside the frame 1.

[0022] As Figure 1-4As shown in the figure, in order to quickly splice and combine each frame 1, the splicing and positioning assembly includes a screw 3, a positioning column 4, a worm 5, a worm gear 6, a guide rail 7, a slider 8 and a fixed column 9. The screw 3 is rotatably connected inside the frame 1, and the positioning column 4 is threadedly connected to one end of the screw 3. A servo motor 10 is fixedly connected inside the frame 1, and the worm 5 is fixedly connected to the output end of the servo motor 10. The guide rail 7 is fixedly installed inside the frame 1, and the slider 8 is fixedly connected to the positioning column 4. One end of the slider 8 is slidably arranged on the guide rail 7. The fixed column 9 is fixedly connected to the inner top of the frame 1, and a through hole 11 is provided on the fixed column 9. A through hole 12 is provided on the plug post 2, and the positioning column 4 is adapted to the through hole 11 and the through hole 12.

[0023] In order to improve the connection strength between each frame 1, a right-angle connector 13 is provided at the connecting corner of the frame 1. The right-angle connector 13 is connected to the frame 1 by bolts. A half-ring 14 is fixedly connected to the frame 1, and a connecting rod 15 is detachably connected to the half-ring 14.

[0024] Among them, a hanging groove 16 is provided on the outer side wall of the frame 1, and the hanging grooves 16 are symmetrically arranged.

[0025] During specific use, when assembling the frame 1, insert the plug post 2 on the frame 1 into the inside of another group of frames 1, so that the plug post 2 is inserted outside the fixed column 9. Then turn on the servo motor 10, and the worm 5 drives the worm gear 6 to rotate. The rotation of the worm gear 6 causes the screw 3 to rotate. The positioning column 4 moves horizontally under the limiting and guiding action of the slider 8 and the guide rail 7. Therefore, the positioning column 4 passes through the through hole 12 and the through hole 11, and the plug post 2 and the fixed column 9 are inserted and connected, thus completing the fixation of the plug post 2. Then install the right-angle connector 13 at the right-angle connection of the frame 1 by bolts. Finally, connect the connecting rod 15 between the half-rings 14, and the overall assembly and fixation can be completed. The assembly process is simple and easy to operate, reduces the use of bolts, and improves work efficiency.
