8. The repair apparatus for a road surface expansion joint for road maintenance according to any one of claims 1 to 7, wherein: the method specifically comprises the following steps:
s1: moving the repairing equipment to one end of the expansion joint to be repaired through a moving wheel (2014), and driving a threaded column (2037) to enable a coaming (2034) to be downward by driving a servo motor II (2032), so that a partition plate (2036) extends into a specified position in the expansion joint until the bottom of the partition plate (2036) contacts the inner wall of the bottom of the expansion joint;
s2: according to the positions of two sides of the expansion joint, a bidirectional screw rod (2021) is driven by a driving servo motor I (2022), so that two groups of movable blocks (2023) drive a U-shaped seat to further drive two groups of side surrounding edge assemblies (201) to be close to the expansion joint, the surrounding edge plates (2011) on the left side and the right side are respectively positioned on two sides of the expansion joint, and at the moment, the surrounding edge plates (2011) on the left side and the right side and a partition plate (2036) separate the expansion joint to perform one-section repairing operation;
s3: the electric telescopic rod is driven to drive the material injection nozzle (105) to enter the expansion joint, the waterproof asphalt material in the material box (102) is injected into the expansion joint through the pump body (103), the material injection is stopped after the filled waterproof asphalt material reaches a specified height, and the material injection nozzle (105) is driven to move by the air cylinder (107) to perform uniform injection during material injection;
s4: after injecting into, drive electric telescopic handle drives and annotates material mouth (105) to the clamp plate (301) top upwards, drive two-way lead screw (2021) through drive servo motor one (2022), thereby make two sets of movable block (2023) drive the U-shaped seat and then drive two sets of side surrounding edge subassembly (201) and be close to each other, carry out the block through constant head tank (302) and locating piece until clamp plate (301) on the left and right sides, at this moment, open miniature driving motor (303) again and drive bull stick (304) and make cam (305) rotate, press the cover through reciprocal extrusion clamp plate (301) of cam (305) to the waterproof pitch material of packing, after flattening, remove the device, segment the expansion joint again, then carry out above-mentioned operation to the expansion joint of segmentation part again and repair can.
