[0039] It should be noted that the present invention is a road bridge surface detection device. Before use, the device is placed in a required location. The device can be divided into four usage scenarios according to the needs of bridge detection; Scenario 1: When the bridge deck needs to be inspected, the device is placed on the bridge deck that needs to be inspected, and then the motor 19 is started to rotate the bidirectional screw 7 until the bidirectional screw 7 acts on the two sliders 10 to slide toward the middle of the rack 6 to a suitable position and then stops, and then the motor 2 14 is started to work, so that the transmission gear 12 and the transmission gear 2 16 are meshed, until the hollow plate 17 rotates 90 degrees and stops, at which time the hollow plate 17 is parallel to the ground and the auxiliary wheel 18 is in contact with the ground, and then the hand is pinched The two sliders 3 23 make it move toward the middle of the slide bar frame 22. At this time, the limit rod 24 is pulled out from the limit hole corresponding to the baffle 20, and the limit of the slider 21 is released. The slider 21 is manually pushed to the direction of the storage rack 1 6 to a suitable position and then stopped, and the slider 3 23 is released. The spring 25 loses its force and rebounds with the slider 3 23 and the limit rod 24, so that the limit rod 24 is inserted into the limit hole corresponding to the baffle 20. At this time, the slider 21 is restricted, and the staff can push the vehicle body 1 forward to inspect the bridge deck; Scenario 2: When it is necessary to inspect the bridge deck and inner wall of the bridge at the same time, based on the use scenario 1, one of the motors 2 14 is started to rotate the movable plate 15 90 degrees and then stop. At this time, one of the movable plates 15 is perpendicular to the ground, and the movable plates 15 on both sides of the rack 1 6 form a 90-degree angle. Then, as needed, the slider 2 21 is adjusted to a suitable position and fixed so that the detection probe 2 is in a suitable detection position. Then, the vehicle body 1 is moved to a suitable position so that the auxiliary wheel 18 of the hollow plate 17 perpendicular to the ground fits with the inner wall of the bridge. At this time, the two detection probes 2 of the device correspond to the bridge deck and the inner wall of the bridge respectively. The staff can push the vehicle body 1 so that the device can detect the bridge deck and the inner wall of the bridge at the same time. Scenario 3: When it is necessary to inspect the inner and outer walls of the bridge at the same time, based on Scenario 1, first remove the screw 30 to remove the restriction of the rotating disk 28, then rotate the rotating disk 28 by 90 degrees, and then install the screw 30 at the corresponding positions of the protrusion 27 and the protrusion 3 29 to fix the rotating disk 28, and then start the multi-stage electric telescopic rod 1 31 to lift the storage rack 2 35 to a suitable height and then stop, and then start the motor 2 14 to rotate the movable plate 1 15 90 degrees toward the ground and then stop, and then start the motor 3 41 to make the gear plate 42 act on the gear ring 43 to mesh until the movable plate 2 39 is rotated 90 degrees and stops , and then adjust the position of the extension plate 36 according to the distance between the vehicle body 1 and the bridge wall, start the multi-stage electric telescopic rod 2 33 to make it act on the extension plate 36 to slide toward the bridge wall until the extension plate 36 slides to a suitable position and stops, and then adjust the height according to the position of the detection probe 2 and the bridge wall, start the multi-stage electric telescopic rod 1 31, and make it move down with the storage rack 2 35 to a suitable position and stop. At this time, the height position of the detection probe 2 and the bridge wall is adapted, and then the position of the slider 10 is adjusted by the motor 1 9 until the auxiliary wheel 18 fits the outer wall and the inner wall of the bridge and stops. At this time, the staff pushes the vehicle body 1 forward to simultaneously detect the outer wall and the inner wall of the bridge; Scenario 4: When the inclination of the bridge wall needs to be detected, based on Scenario 1, the bolt fastener 19 on one side of the rack 16 is removed, and then the hollow plate 17 at the corresponding position is rotated 180 degrees and then the bolt fastener 19 is reinstalled to fix the position of the hollow plate 17. Then, the motor 2 14 is started to rotate the movable plate 15 90 degrees and then stop. At this time, the movable plate 15 is perpendicular to the ground, and the auxiliary wheel 18 of the hollow plate 17 is set in the direction of the rack 16. Then, the multi-stage telescopic rod 48 is rotated 90 degrees. The rotated multi-stage telescopic rod 48 is aligned with the ground. The ground is vertical, and the connecting rod 50 is stuck on the inner side of the elastic clamp 51. The vehicle body 1 is moved to a suitable position on the bridge, and then the motor 2 14 is started to rotate the movable plate 15 toward the bridge wall until the hollow plate 17 is in contact with the bridge wall and stops. During the process, the hollow plate 17 moves through the elastic clamp 51 to move with the connecting rod 50, and the connecting rod 50 acts on the multi-stage telescopic rod 48 to rotate and extend, and the multi-stage telescopic rod 48 moves synchronously with the pointer 49. When the hollow plate 17 is in contact with the bridge wall, the value corresponding to the pointer 49 on the protractor 46 is read to obtain the inclination of the bridge wall.
