Description

Technical Field

[0001] This invention relates to the field of bridge crack repair, specifically to a bridge crack adaptive angle grouting repair device. Background Technology

[0002] Cracks are one of the most common defects in the long-term operation of bridge engineering. Timely pressure grouting is a key repair method to restore the integrity and durability of the structure. At present, bridge crack grouting repair relies on manual or semi-mechanized grouting equipment. Existing grouting repair devices usually simply fix the grouting bucket, grouting pump and other equipment on a wheelbarrow or platform.

[0003] In a single repair task, it is often necessary to use base grout and modified grout sequentially, or use different materials at different work stations. Traditional bolt-plate fixing structures require tools for cumbersome disassembly and installation when changing grouting tanks, which is time-consuming and labor-intensive. This inefficient tank-changing method seriously interrupts the continuity of construction and cannot meet the process requirements of continuous or alternating operation of multiple grouts, becoming a major obstacle to improving the overall repair efficiency. In addition, the fixed clamps are difficult to adapt to grouting tanks of different specifications on the construction site, resulting in insufficient flexibility. Therefore, we have proposed an adaptive angle grouting repair device for bridge cracks. Summary of the Invention

[0083] Working principle: After the equipment is in place, the operator first manually pushes the square sleeve 8. The movement of the square sleeve 8 is converted into torque on the double-screw 20 through the limiting rod 23, causing it to rotate. Since the slider 21 meshes with the left and right threaded sections of the double-screw 20, and its movement is constrained by the sliding pair between the limiting rod 23 and the cross hole 22, when the double-screw 20 rotates, the four sliders 21 are driven synchronously and move towards each other in pairs. This causes the four square sleeves 8 fixed at the end of the limiting rod to close from the four sides, precisely clamping the grouting tank 3 placed on the top surface of the rotating table 2. After the grouting tank is fixed laterally, the operator manually pulls out the handle-type fixing... Positioning ring 11 disengages its insert rod 32 from the insertion hole 33 on the square sleeve 8. At this time, positioning ring 11, through its internal connecting rod 31 and the sliding hole 30 on the rotating shaft 12, still maintains an axial sliding and circumferential linkage relationship with the rotating shaft 12. The operator can then rotate positioning ring 11 to drive the rotating shaft 12 to rotate. The rotation of the rotating shaft 12, through a pair of meshing bevel gears 29 and 28, converts the vertical rotational motion into horizontal rotational motion, thereby driving the lead screw 24 to rotate. The telescopic column 9, which meshes with the lead screw 24 through the threaded hole 34, cannot rotate under the sliding constraint of the limiting block 26 and the strip hole 27. It can only extend along the axial direction of the square sleeve 8, eventually causing the pressure plate 10 fixed at its top to be stably pressed against the top edge of the grouting tank 3. After pressing, the positioning ring 11 is released, and the positioning ring 11 is pushed to make the insertion rod 32 re-insert into the insertion hole 33, locking the rotating shaft 12 to prevent it from loosening during vibration. When grouting is required for cracks with different spatial angles, the rotation positioning program is started. The central controller sends a command to the motor 15 according to the preset or real-time visual recognition of the crack angle. The motor 15 drives the gear 18 to rotate, and through meshing with the gear 17 fixed on the rotating tube 14, it drives the rotating tube 14 to rotate between the support column 13 and the bearing 19. The rotating mechanism forms a smooth rotation, and the rotating pipe 14 drives the entire rotating table 2 and all its components, including the clamped and fixed grouting tank 3, the grouting pump 5, and some pipelines, to rotate together to the optimal working angle. The relative position between the grout delivery pipe 4 and the grouting tank 3 remains unchanged, and the grout delivery path is smooth. At the same time, the grouting hose 6 only needs to be bent to a minimum to connect with the grouting nozzle 7. Finally, the grouting procedure is executed. The system starts the grouting pump 5 installed on the rotating table 2. The grout is pumped from the bottom of the grouting tank 3 through the grout delivery pipe 4, and through the grouting hose 6, it is finally continuously and high-pressure injected into the depth of the crack by the grouting nozzle 7 that has been inserted into the crack.
