[0002] High-speed railway, referred to as HSR, refers to a railway system with high design standards that can enable trains to travel safely and at high speeds. In order to maintain the smooth operation of the HSR, it is usually necessary to reduce changes in the HSR, so a large number of elevated bridges and tunnels will be used. When crossing rivers and other areas, the piers under the bridge will be located below the water surface. Long-term immersion in water will cause different corrosion and damage to the surface of the piers. Therefore, it is necessary to regularly inspect the surface of the piers and repair the piers in time to ensure the safety of the high-speed rail.

[0003] However, the existing bridge pier inspection equipment, especially underwater inspection, requires the inspection equipment to be moved to the position where the bridge pier is located on the water surface by means of transportation equipment during the inspection process, and then the inspection mechanism is moved underwater by means of a lifting rope or the like to inspect the surface of the bridge pier. The existing inspection method usually adopts the method of shooting with a camera, and many hidden dangers cannot be detected.

The movable plate scrapes and cleans the silt impurities attached to the outside of the pier through the outer scraper. At the same time, the water sucked into the second water pipe will be sprayed out through the water spray port to flush and clean the scraped silt. At the same time, the baffle can intercept the silt to prevent the flushed silt from entering the detection cavity, thereby improving the detection effect. BRIEF DESCRIPTION OF THE DRAWINGS

The side of the impact hammer 8 is connected to a limit clamp 801, and the limit clamp 801 extends to the inside of the detection mechanism 3. The detection mechanism 3 has limit plates on both sides extending between the limit clamps 801.

The mobile crane 2 moves in the moving groove 101 through the moving mechanism 201, and can drive the detection mechanism 3 to move along the outside of the pier, so as to facilitate the detection of the pier.

[0045] See also Figure 3 The mobile crane 2 is internally installed with a hoisting motor 202, multiple sets of traction rollers, a traction rope 203 and a wire 204. The traction rope 203 and the wire 204 are respectively wound around different traction rollers, and the multiple sets of traction rollers are transmission-connected to the hoisting motor 202, so that the detection mechanism 3 can be conveniently moved, and is connected to external equipment through the wire 204 when moving.

[0046] See also Figure 3 A detection cavity 301 is opened on the side of the detection mechanism 3, the adsorption roller 5, the collection camera 7 and the impact hammer 8 are all located inside the detection cavity 301, and the outer side of the detection mechanism 3 is located at the upper and lower positions of the detection cavity 301 and is connected with a buffer pad 302, and the inner wall of the detection cavity 301 is located at the outer side of the adsorption roller 5 and has a cleaning plate 304, and a baffle 303 is installed on the outer side of the detection cavity 301 near the movable plate 4, which can facilitate the fitting connection between the detection mechanism 3 and the bridge pier and reduce the interference of water flow.

[0047] See also Figures 6 to 9A first water pipe 16 is connected between the suction nozzle 15 and the driving box 12, a second water pipe 17 is connected to the inside of the swing plate 6, and the end of the second water pipe 17 extends to the inside of the movable plate 4 and is connected to each group of water spray ports 402.

[0048] The working principle of the present invention is as follows: first, the equipment is installed on the outside of the bridge pier, and the mobile crane 2 and the detection mechanism 3 are installed and limited through the detection platform 1. When in use, the detection mechanism 3 is first connected to the control device of the outside personnel through the wire 204, and then the hoisting motor 202 is started. The hoisting motor 202 drives multiple groups of winding rollers to rotate (the wire is also connected to the motor through a group of winding rollers, and the transmission method can be gear transmission), so that the traction rope 203 and the wire 204 are extended, and the detection mechanism 3 enters the water surface under the action of gravity. At this time, the output motor 14 in the detection mechanism 3 is started, and the output motor 14 drives the multiple groups of driven wheels 13 to rotate outside the driving box 12 through the transmission structure. The driven wheel 13 first drives the fan blades 1303 to rotate inside the driving box 12, and sends the external water into the second water pipe 17 through the adsorption nozzle 15 and the first water pipe 16. At this time, the negative pressure generated by the adsorption nozzle 15 will pass through the adsorption roller 5 to the outside, and the adsorption roller 5 is close to the outside of the pier, so that the adsorption roller 5 drives the detection mechanism 3 to be adsorbed on the outside of the pier, so that the two groups of acquisition cameras 7 can The outer wall of the pier is detected by collecting camera 7. At this time, the moving mechanism 201 is started. The moving mechanism 201 drives the moving crane 2 and the detection mechanism 3 to move through two sets of driving wheels, so that the detection mechanism 3 moves on the outer wall of the pier to perform all-round detection on the outer side of the pier. During the detection, the driven wheel 13 will also drive the rotating disk 1301 to rotate. The rotating disk 1301 slides in the slide groove 601 through the outer transmission rod 1302, thereby driving the swing plate 6 to swing up and down, and the swing plate 6 drives the outer movable plate 4 to move up and down synchronously, and this When the scraper 401 is in contact with the outside of the pier, the scraper 401 swings up and down to scrape and clean the silt impurities attached to the outside of the pier, thereby improving the shooting effect of the acquisition camera 7. At the same time, the water flow entering the second water pipe 17 will be sprayed out through the water spray port 402 to clean the silt accumulated on the outside of the scraper 401, thereby improving the cleaning effect of the scraper 401. The baffle 303 can clean the impurities remaining on the outside of the pier, and at the same time, block the silt when the scraper 401 is cleaning, thereby reducing the silt from entering the detection cavity 301 and improving the detection effect.

[0049] When the swing plate 6 moves up and down, the top block 602 connected to the outside of the swing plate 6 will also move up and down, repeatedly impacting and squeezing the squeezing push block 803. The squeezing push block 803 will squeeze the return spring 802 and push the limit clamp 801 to move. The limit clamp 801 drives multiple groups of impact hammers 8 to knock on the outer wall of the pier, and the impact hammer 8 is located between the two groups of acquisition cameras 7. The two groups of acquisition cameras 7 respectively synchronously collect the conditions before and after the outer wall of the pier is impacted, so as to accurately check the conditions on the outside of the pier, reduce the probability of residual hidden dangers, and improve the detection effect. After the detection mechanism 3 surrounds the pier, the output motor 14 is turned off. At this time, the suction nozzle 15 no longer generates negative pressure for adsorption, and the detection mechanism 3 is separated from the outside of the pier. At this time, the hoisting motor 202 is started to drive the detection mechanism 3 to move, so that the detection mechanism 3 also detects other positions of the pier.
