[0023] See also Figure 1-4 , a pavement crack detection mechanism for road and bridge inspection, comprising a base 1, with a cleaning mechanism 2 arranged above the base 1;

[0024] The cleaning mechanism 2 includes a collecting box 201, the bottom surface of the collecting box 201 is fixedly connected to the upper surface of the base 1, the inner wall of the collecting box 201 is slidably connected to a filter plate 202, and an air pump 203 is fixedly installed on the front of the collecting box 201. The input end of the air pump 203 passes through the collecting box 201 and extends to the interior of the collecting box 201. Two limit frames 3 are fixedly installed on the bottom surface of the base 1, and moving wheels 4 are fixedly installed at both ends of each limit frame 3. The moving wheels 4 can be limited by the limit frames 3, thereby facilitating the movement of the device and increasing the convenience of moving the device.

[0025] The output end of the vacuum pump 203 passes through the base 1 and is fixedly installed with a three-way air supply hose 204. Two fixing brackets 205 are fixedly installed on the upper surface of the base 1. The bottom surface of each fixing bracket 205 is fixedly installed with an electric telescopic rod 206. Two fixing plates 5 are fixedly installed on the upper surface of the base 1. A handle 6 is fixedly installed on the front of each fixing plate 5. The handle 6 can facilitate personnel to operate the device, thereby facilitating the repair of cracks in different positions, increasing the convenience of the device.

[0026] The telescopic ends of the two electric telescopic rods 206 are jointly fixedly installed with a collection rack 207. The inner wall of the collection rack 207 is fixedly connected to the outer surface of the three-way gas hose 204. The outer surface of the three-way gas hose 204 is fixedly connected with equidistantly arranged blowing heads 208. The left side of the collection box 201 is movably hinged with a switch door 7. The left side of the switch door 7 is fixedly installed with a handle 8. The switch door 7 can be manually opened through the handle 8, so that it is convenient for personnel to collect the collected debris in a centralized manner, thereby increasing the convenience of debris collection.

[0027] The back of the collection box 201 is fixedly connected to a delivery hose 209, and the end of the delivery hose 209 away from the collection box 201 is fixedly connected to the upper surface of the collection rack 207. A support frame 9 is fixedly installed on the upper surface of the base 1, and a camera 10 is fixedly installed on the back of the support frame 9. The support frame 9 is L-shaped, so that the camera 10 can be supported and protected. The camera 10 can be limited and fixed by the support frame 9, so that the camera 10 can take pictures of cracks in the road surface, which increases the practicality of the device.

[0028] A limiting cylinder 11 is fixedly installed on the bottom surface of the base 1. The inner wall of the limiting cylinder 11 contacts the outer surface of the three-way gas hose 204. The limiting cylinder 11 can limit the three-way gas hose 204, thereby preventing the three-way gas hose 204 from being entangled, further increasing the practicality of the device.

The limiting groove 12 can limit the roller 13 so that the roller 13 can roll on the ground, thereby facilitating the movement of the collection rack 207.

[0030] The working principle of the present invention is as follows: when in use, first connect the vacuum pump 203 and the electric telescopic rod 206 to the power supply. When it is necessary to detect cracks on the road surface of a bridge, manually hold the handle 6 to move the device through the moving wheel 4, and the elasticity provided by the electric telescopic rod 206 can drive the collection rack 207 to move downward, and the suction force provided by the vacuum pump 203 can be used to extract the air in the collection box 201. The extracted air is directly transported to the blowing head 208 through the guidance of the three-way air supply hose 204, so that the blowing head 208 can spray air, thereby blowing up the debris on the road surface and the cracks in the road surface, and the collection rack 207 can block the blown debris, thereby preventing the debris from flying around. After the air inside the collecting box 201 is extracted, the inside of the collecting box 201 can be in a negative pressure state, so that the conveying hose 209 can directly convey the debris into the collecting box 201, and the filter plate 202 can block the incoming debris, thereby facilitating the centralized collection of the debris. The support frame 9 can limit and fix the camera 10 so that the camera 10 can take pictures of the road cracks, so that before detecting the road cracks, it is convenient to clean up the debris on the road surface to prevent the debris from covering the cracks or remaining inside the cracks and affecting the accuracy of the road crack detection. The switch door 7 can be manually opened by manually holding the handle 8, thereby facilitating the removal of the collected debris, making the road crack detection mechanism for road and bridge inspection more practical.
