Description

[0002] Piers are the lower load-bearing objects used to support the upper structures in civil engineering. The cross-section of piers is mostly circular. They are an important part of bridge projects such as highway bridges, railway bridges, overpasses, ramp bridges, and flyovers. Regular inspection and disease analysis of bridge piers are of great significance to ensure the safe operation of bridges.

[0003] At present, manual inspection is generally used for bridge piers. First, the measuring points are marked on the piers, and then an appropriate amount of coupling agent is applied to the corresponding measuring points. Then, ultrasonic inspection of the piers is carried out at the corresponding measuring points on both sides through the cooperation of ultrasonic transducers, receiving transducers and other inspection devices.

[0053] The working process of the bridge pier detection device is as follows:

[0054] First, the frame 100 is connected to the outside of the bridge pier by splitting and splicing, and then the cylinder 105 is started, and the adjustment block 106 is moved by the telescopic control of the output end of the cylinder 105 to push the track-driven vehicle 107, and further control the stress between the track-driven vehicle 107 and the pier. By applying appropriate stress, it is ensured that sufficient friction is maintained between the track-driven vehicle 107 and the pier, thereby providing a stable climbing driving force, and the track-driven vehicle 107 is driven to rotate by the motor 108. , driving the frame 100 to crawl on the outer wall of the pier. During the crawling process, the upper and lower sets of arc rollers 102 are pulled toward the connection point of the connecting rod 103 through the tension of the springs between the connecting rods 103, and the rotation of the rotating rod 109 is coordinated to make the arc rollers 102 always keep in contact with the outer wall of the pier. During the up and down crawling of the frame 100, the arc rollers 102 are used to pre-clean the area that the detection tube 200 is about to reach, thereby reducing interference from impurities and aquatic organisms on the outer wall of the pier and improving the accuracy of subsequent detection results.

[0055] During the inspection, during the upward crawling inspection process, when inspecting the pier above the frame 100, the motor 201 slides to the highest point in the sliding groove of the arc-shaped bracket 101, and the rotating base 202 and the motor 3 203 are rotated and adjusted to control the detection end of the detection tube 200 to face the direction of the pier, and at the same time adjust the angle of the detection tube 200 so that the discharge groove 210 is facing downward. Further, the output end of the cylinder 207 controls the detection head 204 to advance toward the pier. During this process, the ball 209 on the side wall of the detection head 204 first contacts the straight part of the driving groove 208 until the detection end of the detection head 204 contacts the bottom of the auxiliary rod 300, refer to Figure 7At this time, the roller at the bottom of the slider 2 309 contacts the end of the detection head 204, the auxiliary rod 300 is parallel to the surface of the detection head 204, and the block 308 moves downward under the attraction of the slider 2 309, so that the pipe 2 305, the pipe 1 304 and the discharge hole 303 are connected, and the coupling agent inside the feed pump 213 enters through the pipe 2 305 and is discharged to the surface of the detection head 204 through the discharge hole 303. At the same time, as the detection head 204 continues to advance, the ball 209 advances along the spiral section of the driving groove 208. Since the detection head 204 cannot rotate, it pushes the rotating tube 205 to rotate one circle, so that the auxiliary rod While spraying coupling agent on the end of the detection head 204, 300 rotates around the end of the detection head 204 to achieve rotational and uniform spraying of the coupling agent on the end of the detection head 204. At the same time, the iris mechanism 206 is rotated and opened by rotating the rotating tube 205. Further, when the detection head 204 continues to move toward the pier column, after pushing the slider 301 to the top, it will push the auxiliary rod 300 to rotate until the detection head 204 extends out of the detection tube 200 and fits tightly against the surface of the pier column. The detection heads 204 on both sides synchronously send and receive ultrasonic signals, thereby performing ultrasonic detection on the inside of the pier column.

[0056] It should be noted that the detection head 204 preferably adopts the waterproof ultrasonic transducer in the prior art. The two groups of symmetrically arranged detection heads 204 are respectively a transmitting transducer and a receiving transducer, and are located on the same axis for transmitting and receiving ultrasonic signals to detect the inside of the pier.

[0057] It should be noted that the end of the auxiliary rod 300 away from the slider 1 301 is designed as a magnet, and the end of the detection head 204 is made of stainless steel. When the detection head 204 moves up and contacts the slider 2 309 and continues to move up, the attraction of the magnet at the end of the auxiliary rod 300 to the surface of the detection head 204 can overcome the elastic force of the torsion spring 302 and the spring 1 211, so that in the process of the detection head 204 pushing the auxiliary rod 300 and the slider 1 301 to move up and compressing the spring 1 211, the auxiliary rod 300 can remain parallel to the end of the detection head 204 through magnetic force, and with the design of the slider 2 309 and its bottom roller, there is a certain distance between the auxiliary rod 300 and the detection head 204, so that the coupling agent smoothly sprayed out from the end of the discharge hole 303 can be evenly coated on the surface of the detection head 204.

[0058] After the detection is completed, when the detection head 204 retracts into the detection tube 200, the ball 209 is reset along the driving groove 208, first passing through the straight part of the driving groove 208, then passing through the spiral part of the driving groove 208, and further passing through the straight part at the other end of the driving groove 208 to complete the reset. In this process, when the detection head 204 retracts through the auxiliary rod 300, the auxiliary rod 300 rotates and resets under the elastic reset action of the torsion spring 302. Different from the initial contact, during the reset process, the edge of the detection head 204 slides along the bottom of the auxiliary rod 300, and when it contacts the slider 2 309, it contacts the side wall of the slider 2 309 and pushes the slider 2 309 toward the direction of the slider 1 301. At this time, refer to Fig.10 The auxiliary rod 300 is adsorbed on the top of the detection head 204 by the magnetic force at the end of the auxiliary rod 300. During the resetting process of the detection head 204, the cooperation between the ball 209 and the driving groove 208 drives the rotating tube 205 and the auxiliary rod 300 to rotate in the opposite direction, and the auxiliary rod 300 can be driven to rotate along the end of the detection head 204 for one circle, and the coupling agent remaining at the end of the detection head 204 is scraped and cleaned by the scraper 320. As the detection head 204 continues to retract and reset, when the auxiliary rod 300 rotates to tilt toward the detection head 204 under the elastic force of the torsion spring 302, refer to Figure 11-13 Through the cooperation between the protrusion 319 and the push rod 318, when the auxiliary rod 300 rotates until the push rod 318 passes the protrusion 319, the push rod 318 is pushed toward the inside of the limiting groove 317. Through the arc-shaped design at the bottom of the limiting groove 317 and the arc-shaped design at the top of the slider 321, the slider 321 can be pushed away from the clamping of the limiting groove 317, so that the slider 311 is reset under the elastic force of the spring 313, and the coupling agent residue cleaned on the surface of the scraper 320 is pushed away and cleaned, so that the cleaned coupling agent residue is discharged through the sleeve 310 under the action of gravity, thereby realizing automatic cleaning of the scraper 320.

[0059] It should be noted that in the process of the detection head 204 extending and driving the auxiliary rod 300 to rotate upward, the auxiliary rod 300 rotates and drives the gear 1 315 to rotate. The gear 1 315 drives the gear 2 316 and the winding roller 312 to rotate more circles through meshing, tightens and winds the pull rope 314, and compresses the spring 2 313 until the auxiliary rod 300 rotates to the highest point. At this time, the slider 4 321 inside the slider 311 is engaged with the limit groove 317 under the action of elastic force, thereby fixing and storing force on the slider 311 until the detection head 204 is reset. After the scraper 320 completes the cleaning work, after the auxiliary rod 300 rotates to the lowest point, the slider 311 is released and the scraper 320 is cleaned through the cooperation of the protrusion 319 and the push rod 2 318.

[0060] It should be noted that, when the detection head 204 drives the slider 301 to rise to the highest point, the auxiliary rod 300 pushes the push rod 306, so that the push rod 306 applies a thrust to the sleeve 310, and the spring between the sleeve 310 and the push rod 306 is also compressed. When the slider 301 moves to the highest point, under the elastic force of the spring between the push rod 306 and the sleeve 310, the sleeve 310 extends out and engages with the corresponding winding roller 312, so as to realize the sliding block 301. The auxiliary rod 300 is fixed only when the detection head 204 is reset, after the end of the detection head 204 passes through the auxiliary rod 300, the auxiliary rod 300 rotates to reset and disengages from the push on the push rod 306, and the sleeve 310 is retracted and disengaged from the engagement of the slot 212 under the elastic force of the spring between the push rod 306 and the slider 301, so that during the reset process of the detection head 204, the auxiliary rod 300 is synchronously reset with the end of the detection head 204, and the synchronous cleaning effect is achieved on the end of the detection head 204.

[0061] It should be noted that, during the resetting process of the detection head 204, when the detection head 204 pushes the slider 2 309 to move toward the slider 1 301, although the pipe 1 304 and the pipe 2 305 are connected at this time, since the distance between the blocking block 308 and the slider 2 309 becomes larger, the magnetic attraction between them becomes smaller, and the blocking block 308 rises under the elastic force of the spring between the connecting groove 307, thereby blocking the connection between the discharge hole 303 and the pipe 1 304 to avoid the discharge of the coupling agent during resetting.

[0062] When the frame 100 climbs downward to detect the lower part, it is only necessary to control the motor 201 to move downward, and at the same time, by rotating the rotating base 202 and the detection tube 200, and adjusting the detection head 204 to face the pier, the pier in the downward direction can be detected. By adjusting the detection position of the detection tube 200, the detection range of the frame 100 during its movement can be expanded.

[0063] It should be noted that when diving to inspect the underwater pier, a waterproof coupling agent can be used. At the same time, the cleaned coupling agent residue can also be discharged through the discharge chute 210 by gravity sedimentation.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
