A sanding apparatus for bridge work as defined in claim 7, wherein: the transverse motor (33) is fixedly arranged on the right side of the top of the longitudinal displacement plate (29) through a connecting block, a reinforcing plate (36) is fixedly connected to the left side of the top of the longitudinal displacement plate (29), one end of a second threaded rod (34) is rotatably connected with the right side of the reinforcing plate (36) through a bearing, the inner surface of the U-shaped frame (35) is matched with the outer surface of the longitudinal displacement plate (29), and the hydraulic telescopic rod (5) is fixedly arranged on the top of the U-shaped frame (35).
9. A sanding apparatus for bridge work as defined in claim 1, wherein: the right side of assembly plate (6) is through bolt fixed mounting balancing weight (37), and balancing weight (37) set up the right side at hydraulic telescoping rod (5).
10. The polishing method for the bridge engineering is characterized by comprising the following steps of: the method specifically comprises the following steps:
step one, closed polishing: the movable trolley (1) is pushed by the handle (32), the polishing head (11) moves to the bridge floor to be polished, the hydraulic telescopic rod (5) is controlled to shrink, the hydraulic telescopic rod (5) drives the assembly plate (6) to descend, the assembly plate (6) drives the protective frame (12) to enable the rubber pad sleeve (16) to descend through the hanging frame (7), after the rubber pad sleeve (16) contacts with the ground, the protective frame (12) drives the hanging rod (13) to move upwards relative to the hanging frame (7), in the process, the limiting plate (14) stretches the spring (15) until the polishing head (11) contacts with the bridge floor to be polished, the hydraulic telescopic rod (5) is stopped to shrink, the polishing motor (9) is started, the polishing motor (9) drives the rotating shaft (10) to rotate, and the rotating shaft (10) drives the polishing head (11) to polish the bridge floor;
step two, dust removal: in the polishing process, a fan (18) is started, dust generated in the polishing process is conveyed into a collecting box (19) through a dust guide pipe (22) by the fan (18) after passing through a dust suction head (21) and a dust suction hose (20), the dust falls into a collecting basin (23) after being filtered by a first filter screen (24), and air is discharged out of the collecting box (19) after being filtered by a second filter screen (25);
step three, transversely moving: when the polishing head (11) needs to be transversely moved and adjusted, a transverse motor (33) is started, the transverse motor (33) drives a second threaded rod (34) to rotate, so that a U-shaped frame (35) transversely moves along a longitudinal displacement plate (29), and in the process, the U-shaped frame (35) drives a hydraulic telescopic rod (5) to transversely move a mounting plate (6), and the mounting plate (6) drives the polishing head (11) to transversely move through a hanging bracket (7);
step four, longitudinally moving: when the polishing head (11) needs to be longitudinally moved and adjusted, a longitudinal motor (26) is started, the longitudinal motor (26) drives a first threaded rod (27) to rotate, a semicircular block (28) longitudinally moves along a semicircular groove (30), in the process, the semicircular block (28) drives a longitudinal displacement plate (29) to longitudinally move, the longitudinal displacement plate (29) drives a U-shaped frame (35) to enable a hydraulic telescopic rod (5) to enable an assembly plate (6) to longitudinally move, and the assembly plate (6) drives the polishing head (11) to longitudinally move through a hanging bracket (7).
