Detailed Implementation

[0021] Example 1

[0022] like Figures 1-3 As shown in the figure, the caisson tilt correction device proposed in this embodiment includes a top plate 1, a rectangular frame 6, a sliding seat 13, and a clamping mechanism.

[0023] Support sleeves 2 are provided at the four corners of the bottom of the top plate 1; the rectangular frame 6 is slidably installed on the four support sleeves 2. The top plate 1 is equipped with a first drive mechanism for driving the rectangular frame 6 to rise and fall. The first drive mechanism includes a servo reduction motor 9, a drive shaft 11, two winding reels 10, and two high-strength steel wire ropes 12. The drive shaft 11 is rotatably installed on the top plate 1. The servo reduction motor 9 is installed on the top plate 1 and its output shaft is connected to the drive shaft 11. The two winding reels 10 are respectively installed at both ends of the drive shaft 11. One end of the two high-strength steel wire ropes 12 is respectively fixedly wound on the winding reels 10 on both sides. Both high-strength steel wire ropes 12 movably pass through the top plate 1 and are connected to the rectangular frame 6.

[0024] The sliding seat 13 is slidably installed inside the rectangular frame 6. A first slide rod 171 and a second slide rod 172 are slidably installed on the rectangular frame 6. The extension direction of the first slide rod 171 is perpendicular to the extension direction of the second slide rod 172. The second slide rod 172 is slidably connected to the sliding seat 13 and moves through the sliding seat 13. A sliding sleeve 18 is fixed on the sliding seat 13 and is slidably connected to the first slide rod 171. A second drive mechanism for driving the sliding seat 13 to move horizontally is installed on the rectangular frame 6. The second drive mechanism includes a third hydraulic cylinder 15 and a fourth hydraulic cylinder 16. Both the third hydraulic cylinder 15 and the fourth hydraulic cylinder 16 are installed on the rectangular frame 6. The output shafts of the third hydraulic cylinder 15 and the fourth hydraulic cylinder 16 are respectively connected to the second slide rod 172 and the first slide rod 171.

[0025] The clamping mechanism is installed on the sliding seat 13. The clamping mechanism includes a second hydraulic cylinder 14, a lifting column 20, and multiple clamping plates 19. The lifting column 20 is located below the sliding seat 13. At least three clamping plates 19 are provided. Multiple lifting columns 20 are arranged in a circular array around the clamping plates 19. Multiple clamping plates 19 are slidably installed on the sliding seat 13. Multiple connecting rods 21 are movably connected between the lifting column 20 and the multiple clamping plates 19.

[0026] A high-definition camera 22 is installed at the bottom of the lifting column 20. It should be added that the technical solution also includes a controller, which is a PLC controller or a microprocessor controller, and a display screen is installed on the controller. The high-definition camera 22 is electrically connected to the controller. The high-definition camera 22 transmits the images collected from the inside of the caisson to the controller. After processing by the controller, the collected video is displayed on the display screen. The operator can clearly observe the degree of misalignment of the joint between the upper and lower caissons through the display screen, and thus determine whether the two caissons are aligned. Compared with manual observation, its accuracy is higher.

[0027] In this embodiment, when correcting the deviation of a smaller caisson, the device is moved above the caisson opening, so that the lifting column 20 is moved as close as possible to the center above the caisson opening. The first drive mechanism drives the rectangular frame 6 downward, thereby driving the sliding seat 13 and the clamping mechanism downward. In the initial state, the multiple clamping plates 19 are all in a close-closed state, so that the multiple clamping plates 19 are inserted into the inside of the caisson to be corrected. The second hydraulic cylinder 14 is activated to drive the lifting column 20 downward, with the cooperation of multiple connecting rods 21. The lower hydraulic cylinder can drive multiple clamping plates 19 to move outward synchronously until all clamping plates 19 are pressed against the inner wall of the caisson. It should be noted that the two ends of the connecting rod 21 are rotatably mounted on the lifting column 20 and the clamping plates 19, respectively. When all clamping plates 19 are pressed against the inner wall of the caisson, the caisson is in a vertical state. Then, the sliding seat 13 is driven to move horizontally by the third hydraulic cylinder 15 and the fourth hydraulic cylinder 16, thereby driving the caisson to perform horizontal position correction work, so that the upper caisson and the lower caisson are vertically aligned.

[0028] Furthermore, in order to improve the stability of the device during operation, multiple holes can be made on the universal wheel mounting base 3, and long pins can be driven through the holes and driven into the soil, thereby reducing the probability of the device shifting during operation.

[0029] Example 2

[0030] like Figure 1 and Figure 2As shown in the figure, the caisson tilt correction device proposed in this embodiment, compared with the first embodiment, has multiple support sleeves 2 with universal wheel mounting bases 3 installed at their bottom ends, and multiple self-locking universal wheels 5 installed on the universal wheel mounting bases 3. The multiple self-locking universal wheels 5 are set to facilitate the movement of the device.

[0031] To ensure that the roof plate 1 remains level on uneven road surfaces, adjustment mechanisms are installed at the four corners of the roof plate 1 in the technical solution. The adjustment mechanisms include a first hydraulic cylinder 8 and support columns 4. The upper end of the support column 4 is slidably installed inside the support sleeve 2 and its movement passes through the universal wheel mounting seat 3. The first hydraulic cylinder 8 is installed on the roof plate 1 and its output shaft is connected to the support column 4. Activating the first hydraulic cylinder 8 can drive the support column 4 on the corresponding side to rise and fall, thereby adjusting the height of the four support columns 4 respectively, which can force the roof plate 1 to be leveled, helping to ensure the accuracy of subsequent correction work.

[0032] A first level 71 and a second level 72 are installed on two adjacent sides of the top plate 1, respectively. The operator observes the first level 71 and the second level 72 while performing the leveling work until both the first level 71 and the second level 72 show level.

[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
