[0027] The operating principle of this embodiment of the present invention is as follows: The adjustment mechanism utilizes servo motors in conjunction with bidirectional screws to adjust the device's position and posture. During operation, a second servo motor 16 rotates the first bidirectional screw 17, causing the movable block 20 to move along the screw. Simultaneously, a tensioner 21, in conjunction with a rotating belt, synchronously drives the movable block 20 on the second bidirectional screw 19, thereby adjusting the position of the worktable 1. A third servo motor 26 rotates a gear 28, which meshes with a rack 25, moving the work base 14.

[0029] The support assembly includes a support frame 39 installed on the outside of the mobile box 30. The support frame 39 is provided with four groups and distributed in a rectangular array.

The internal thread connection of the support frame 39 is a rotating screw 42. The rotating screw 42 is connected to the support cylinder 40 through a bearing. A rotating handle 43 is installed on the top of the rotating screw 42.

[0030] The operating principle of this embodiment of the present invention is as follows: the retraction mechanism is primarily used to switch between mobile and fixed positions. During operation, the fourth servo motor 32 drives the third bidirectional screw 34 to rotate, driving the adjustment block 35 to move. Through the linkage of the first rotating plate 37, the hinge, and the second rotating plate 38, the moving wheel 31 retracts or extends, achieving both movement and fixation of the device. To achieve fixation, rotating the handle 43 drives the rotating screw 42, pushing the support cylinder 40 downward, allowing the positioning plate 41 to rest against the ground, enhancing the stability of the device.

[0031] Specifically, a method for constructing a roadbed grouting reinforcement device for treating roadbed defects includes the following steps: SS001. Move the roadbed grouting reinforcement device to the construction location of the roadbed damage area; SS002. Start the first servo motor 5 in the vibration mechanism, so that its output shaft drives the first rotating rod 6 to rotate, thereby rotating the cam 7; the cam 7 slides in the limiting groove 12 of the working plate 11, pushing the working plate 11 to reciprocate with the help of the extrusion telescopic rod 9 and the return spring 10, generating vibration for the grouting, which promotes the discharge of internal bubbles; SS003. If the position and posture of the device need to be adjusted, the second servo motor 16 is started to drive the first bidirectional screw 17 to rotate, causing the moving block 20 to move along the screw. At the same time, the tensioner 21 cooperates with the rotating belt to drive the moving block 20 on the second bidirectional screw 19 to move synchronously, thereby adjusting the horizontal position of the workbench 1. In addition, the third servo motor 26 is started to drive the gear 28 to rotate, meshing with the rack 25, moving the working base 14, and cooperating with the sliding wheel 29 to achieve flexible movement and precise positioning of the entire device. SS004. After the device reaches the designated position, start the fourth servo motor 32 to drive the third bidirectional screw 34 to rotate, thereby moving the adjustment block 35. Through the linkage of the first rotating plate 37, the hinge, and the second rotating plate 38, the moving wheel 31 is retracted to fix the device. If the stability of the device needs to be further enhanced, the handle 43 can be turned to drive the rotating screw 42 to rotate, pushing the support cylinder 40 downward to make the positioning plate 41 close to the ground. SS005. When the grouting is completed and the device needs to be moved, the fourth servo motor 32 is started again to extend the moving wheel 31, and the device can be flexibly moved to the next construction position.

[0032] Working principle: When grouting reinforcement is required for the diseased part of the roadbed, the device is first moved to the designated construction position. During the grouting process, in order to avoid the generation of bubbles inside the grouting that affect the reinforcement effect, the first servo motor 5 in the vibration mechanism is started, and its output shaft drives the first rotating rod 6 to rotate, thereby rotating the cam 7. The cam 7 slides in the limit groove 12 of the working plate 11, pushing the working plate 11 to perform reciprocating motion with the help of the extrusion telescopic rod 9 and the return spring 10, generating vibration for the grouting, prompting the internal bubbles to be discharged, thereby ensuring the density of the grouting.

[0033] At the same time, if the position and posture of the device need to be adjusted, the adjustment mechanism can be used to achieve this. The second servo motor 16 is started to drive the first bidirectional screw 17 to rotate, so that the moving block 20 moves along the screw, and the tensioning wheel 21 cooperates with the rotating belt to drive the moving block 20 on the second bidirectional screw 19 to move synchronously, thereby adjusting the horizontal position of the workbench 1; in addition, the third servo motor 26 is started to drive the gear 28 to rotate and engage with the rack 25 to move the working base plate 14, and cooperate with the sliding wheel 29 to realize the flexible movement and precise positioning of the entire device.

[0034] After the device reaches the designated position, the retraction mechanism is activated to secure it. The fourth servo motor 32 is activated, driving the third bidirectional screw 34 to rotate, which in turn moves the adjustment block 35. The first rotating plate 37, the hinge, and the second rotating plate 38 are linked to retract the moving wheel 31, securing the device. When the device needs to be moved, the fourth servo motor 32 is activated again, extending the moving wheel 31, allowing the device to move flexibly. To further enhance the device's stability, the handle 43 can be rotated, driving the rotating screw 42 to rotate, pushing the support cylinder 40 downward, allowing the positioning plate 41 to rest against the ground, thereby improving the device's stability during operation.

[0035] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the invention is defined by the appended claims and their equivalents.

Move the roadbed grouting reinforcement device to the construction location of the roadbed damage area; SS002, start the first servo motor (5) in the vibration mechanism so that its output shaft drives the first rotating rod (6) to rotate, thereby rotating the cam (7); the cam (7) slides in the limiting groove (12) of the working plate (11), pushing the working plate (11) to perform reciprocating motion with the help of the extrusion telescopic rod (9) and the return spring (10), thereby generating vibration on the grouting and promoting the discharge of internal bubbles; SS003. If the position and posture of the device need to be adjusted, the second servo motor (16) is started to drive the first bidirectional screw (17) to rotate, so that the moving block (20) moves along the screw; at the same time, the tensioning wheel (21) cooperates with the rotating belt to drive the moving block (20) on the second bidirectional screw (19) to move synchronously, thereby adjusting the horizontal position of the workbench (1); in addition, the third servo motor (26) is started to drive the gear (28) to rotate and mesh with the rack (25), so that the working base plate (14) moves, and cooperates with the sliding wheel (29) to achieve flexible movement and precise positioning of the entire device; SS004. After the device reaches the designated position, the fourth servo motor (32) is started to drive the third bidirectional screw (34) to rotate, thereby driving the adjustment block (35) to move; through the linkage of the first rotating plate (37), the hinge and the second rotating plate (38), the moving wheel (31) is retracted to achieve the fixation of the device; if it is necessary to further enhance the stability of the device, the handle (43) can be turned to drive the rotating screw (42) to rotate, pushing the supporting cylinder (40) downward to make the positioning plate (41) close to the ground; SS005. When the grouting is completed and the device needs to be moved, the fourth servo motor (32) is started again to extend the moving wheel (31), and the device can be flexibly moved to the next construction position.
