[0035] A fixed bearing plate 1 has six traveling feet 2 rotatably mounted on its lower surface, and each traveling foot 2 has an extension adjustment foot 3 fixedly mounted at its end.
[0036] The grouting adjustment mechanism 4 is fixedly mounted on the upper surface of the fixed bearing plate 1, and the grouting adjustment mechanism 4 is externally connected to a grout conveying device;
[0037] In a preferred embodiment, the arrangement of the six traveling feet 2 allows the device to operate without being affected by the grout under its feet, enabling it to freely change positions and thus perform grouting operations more effectively. Furthermore, the traveling feet 2 can adjust the relative height of the fixed bearing plate 1, allowing it to adapt to more complex grouting conditions. The extension adjustment feet 3 further expand the adjustment range of the device and allow it to move on different foundation pit surfaces, thereby further improving grouting efficiency. The grouting adjustment mechanism 4 can fix the external grouting pipe and adjust the relative position of the grouting pipe and the device within a certain range, enabling the device to cope with more complex foundation pit conditions and thus maximizing grouting efficiency.
[0038] Furthermore, the traveling foot 2 includes:
[0039] The first drive motor 21 is rotatably mounted on the lower surface of the fixed support plate 1, and the output shaft of the first drive motor 21 is fixedly mounted on the fixed support plate 1.
[0040] A first fixed plate 22 is fixedly mounted on one side of the first drive motor 21. A telescopic adjustment group 23 is fixedly mounted on the other side of the first fixed plate 22. A first connecting rod 24 is rotatably mounted at one corner of the first fixed plate 22. A second connecting rod 25 is rotatably mounted at the other end of the first connecting rod 24. A sleeve block 26 is slidably fitted at the lower end of the second connecting rod 25. A compression spring 27 is provided between the second connecting rod 25 and the sleeve block 26.
[0041] There are two telescopic adjustment groups 23. One is fixed at one end to the first fixed plate 22 and rotatably mounted on the first connecting rod 24. The other is fixed at one end to the first connecting rod 24 and rotatably mounted on the second connecting rod 25.
[0042] In a preferred embodiment, the first drive motor 21 allows the traveling foot 2 to rotate, thereby adjusting the traveling angle. The two telescopic adjustment groups 23 can change the overall shape of the traveling foot 2, thereby changing the relative height of the fixed bearing plate 1, which facilitates grouting. The compression spring 27 and the sleeve block 26 can play a shock absorption role, which can further improve the grouting efficiency while protecting the safety of the device.
[0043] Furthermore, the telescopic adjustment assembly 23 includes:
[0044] The first fixed shell 232 is fixedly assembled on the first fixed plate 22 or the first connecting rod 24;
[0045] The second drive motor 231 is fixedly assembled inside the first fixed housing 232, and a universal connector 233 is fixedly assembled on the output shaft of the second drive motor 231. An adjusting bolt 235 is fixedly connected to the other end of the universal connector 233. A rotating connecting block 234 is threaded on the adjusting bolt 235. The rotating connecting block 234 is rotatably mounted on the first connecting rod 24 or the second connecting rod 25.
[0046] In a preferred embodiment, when the second drive motor 231 rotates, the universal connector 233 will drive the adjusting bolt 235 to rotate, thereby adjusting the relative position of the second drive motor 231 and the rotating connecting block 234, so as to change the overall shape of the traveling foot 2.

[0049] The other end of each of the three telescopic support rods 33 is respectively provided with a damage protection sleeve 35, a climbing cone 36, and a fixed suction cup 37;
[0050] In a preferred embodiment, the telescopic support rod 33 has a long telescopic range, which can further adjust the working range of the device and raise the device to prevent the grout from damaging the components of the device during grouting. Furthermore, the appropriate telescopic support rod 33 can be selected for movement according to the specific foundation pit conditions via the third drive motor 31. After selection, the other two sets of telescopic support rods 33 will fold under the drive of their respective fourth drive motors 34 to further improve grouting efficiency. The anti-damage sleeve 35, the climbing cone 36, and the fixed suction cup 37 are adapted to different ground conditions. For example, when the device needs to move on a flat surface, the anti-damage sleeve 35 is used to further reduce wear and increase service life. When the device needs to move on a slope in the foundation pit and the ground is soft (soil surface), it needs to switch to the climbing cone 36, which can penetrate the ground to achieve fixation. When the device needs to move on a slope in the foundation pit and the ground is hard (concrete surface), it needs to switch to the fixed suction cup 37, which adheres to the ground.
[0051] Furthermore, the grouting adjustment mechanism 4 includes:
[0052] Support frame 41 is fixedly assembled on the upper surface of the fixed bearing plate 1;
[0053] The second fixing block 42 has two mirror images. Each second fixing block 42 has a vertically mounted sliding column 43. The upper end of the sliding column 43 is fixed to the support frame 41, and a sliding lifter 44 is slidably mounted on each sliding column 43. A horizontal support frame 45 is horizontally mounted between the two sliding lifters 44. A sliding rail 46 is slidably mounted on the lower end of the horizontal support frame 45, and a sliding block 47 is slidably mounted on the upper end of the sliding rail 46. A grouting fixture 48 is fixedly mounted on the sliding block 47.
[0054] In a preferred embodiment, the grouting fixer 48 is mainly used to fix the external grouting pipe. Meanwhile, the other components on the grouting adjustment mechanism 4 form a support frame that can move along multiple axes, thereby ensuring that the grouting fixer 48 can move freely within a specified range. This allows for further adjustment of the relative position and relative height of the grouting point, thereby further improving the grouting quality.
[0055] Furthermore, the grouting fixation device 48 includes:
[0056] The second fixing plate 481 is fixedly mounted on the sliding block 47. The second fixing plate 481 is rotatably provided with a first gear 482, and the lower end of the first gear 482 is meshed with a second gear 483. The upper end is meshed with three circumferentially arranged clamping blocks 485. The three clamping blocks 485 are slidably disposed on the second fixing shell 484. The second fixing shell 484 is fixed on the second fixing plate 481.
[0057] The second gear 483 is externally connected to a driver.
[0058] Furthermore, the lower end of the first gear 482 has teeth that mesh with the second gear 483, while the upper end has a helical groove that meshes with the clamping block 485.
[0059] The specific implementation includes the following steps: placing the device in the foundation pit to be grouted, and fixing the grouting pipe to the grouting fixing device 48 of the grouting adjustment mechanism 4. At the same time, adjusting the relative positions of each component according to the specific requirements of grouting, and then driving the device to grout in the order of outside to inside and bottom to top. During the grouting process at the same grouting point, the grouting adjustment mechanism 4 will drive the grouting fixing device 48 to move upward, so that the grout and the grouting pipe are kept at a certain height, preventing the grouting pipe from getting blocked, and reducing the splashing of grout. This improves the grouting efficiency and further improves the grouting quality.
