Description

Technical Field

[0001] The present invention relates to the technical field of bridge detection, and more particularly to a bridge pier detection device. Background Art

[0002] A pier is a lower load-bearing structure used to support the upper structure in civil engineering. The cross-section of a pier is mostly circular, and it is an important part of bridge projects such as highway bridges, railway bridges, overpasses, ramp bridges, and skybridges. Regular inspection and disease analysis of bridge piers are of great significance for ensuring the safe operation of bridges.

[0003] Currently, manual inspection is generally used for bridge piers. First, measurement points are marked on the pier, then an appropriate amount of coupling agent is applied at the corresponding measurement point positions, and then ultrasonic detection of the pier is carried out through the cooperation of detection devices such as ultrasonic transducers and receiving transducers at the corresponding measurement points on both sides. However, when operating manually, for relatively high piers, climbing is still required to conduct a full-range inspection of the upper part of the pier, and when detecting cross-water bridges, it is also necessary to dive underwater to detect the underwater part of the pier. This is not only troublesome to operate but also has a certain degree of danger.

The first motor 108 is connected to the support frames, and the output shaft of the first motor 108 is in transmission connection with the drive wheels, so as to drive the crawlers of the crawler drive vehicle 107 to rotate, thereby driving the device to climb and lift on the surface of the pier column.

[0044] It should be noted that the second motor 201 is an orbital motor and can slide along the inner chute of the arc-shaped bracket 101.

[0045] Refer to Figure 1 , rotating rods 109 are arranged at both the top and bottom of the frame 100.

It should be noted that the attached drawings are only for display and reference. In actual design and production, the second pipeline 305 can be misaligned with the first push rod 306, so that the first slider 301 will not interfere with or affect the first push rod 306 or the sleeve 310 during the lifting process.

[0048] Referring to Figure 4-13 , the cleaning component includes a second spring 313 arranged on the side wall of the auxiliary rod 300. A third slider 311 connected to the second spring 313 is slidably connected to the side wall of the auxiliary rod 300. A scraping blade 320 is arranged on the side wall of the auxiliary rod 300.

A limiting component is arranged inside the first slider 301. Discharge grooves 210 are formed in the side walls of the rotating tube 205 and the detection tube 200.

[0049] Referring to Figure 12-13 , the release component includes a limiting groove 317 formed inside the auxiliary rod 300. A second push rod 318 is sleeved inside the limiting groove 317.

A sleeve 310 cooperating with the clamping groove 212 is sleeved on the end of the first push rod 306 away from the auxiliary rod 300. A spring is arranged between the sleeve 310 and the first push rod 306.

[0052] It should be noted that a driving groove 208 is formed in the inner side wall of the rotating tube 205. The two ends of the driving groove 208 are designed as straight lines, and the middle part of the driving groove 208 is a spiral design. A ball 209 is arranged on the outer side wall of the detection head 204 and is matched with the driving groove 208.

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

[0054] First, the frame 100 is sleeved on the outer side of the bridge pier by means of disassembly and splicing. Then, the first cylinder 105 is started, and the output end of the first cylinder 105 is extended and retracted to control the movement of the adjusting block 106, pushing the crawler drive vehicle 107, and further controlling the stress between the crawler drive vehicle 107 and the pier. By applying appropriate stress, sufficient friction is ensured between the crawler drive vehicle 107 and the pier, thereby providing a stable climbing driving force. The crawler drive vehicle 107 is driven to rotate by the first motor 108, driving the frame 100 to crawl on the outer side wall of the pier. During the crawling process, the upper and lower groups of arc rollers 102 are simultaneously pulled towards the connection of the connecting rods 103 by the tension of the springs between the connecting rods 103. With the rotation of the rotating rod 109, the arc rollers 102 are always kept in contact with the outer side wall of the pier. During the up and down crawling of the frame 100, the area where the detection tube 200 is about to reach is pre-cleaned by the arc rollers 102, reducing the interference of impurities and aquatic organisms on the outer side wall of the pier and improving the accuracy of the subsequent detection effect.

[0055] During the detection, when crawling upward for detection and detecting the pier above the frame 100, the second motor 201 slides to the highest position in the chute of the arc-shaped bracket 101, and the rotating base 202 and the third motor 203 rotate and adjust to control the detection end of the detection tube 200 to face the direction of the pier. At the same time, the angle of the detection tube 200 is adjusted so that the direction of the discharge groove 210 is downward. Further, the output end of the second cylinder 207 controls the detection head 204 to push towards 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 7, at this time, the roller at the bottom of the second slider 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 blocking block 308 moves downward under the attraction of the second slider 309, so that the second pipeline 305, the first pipeline 304 and the discharge hole 303 are communicated. The coupling agent inside the feeding pump 213 enters through the second pipeline 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, the rotating pipe 205 is pushed to rotate one circle, so that while the auxiliary rod 300 sprays the coupling agent on the end of the detection head 204, it rotates around the end of the detection head 204 to realize the rotary and uniform spraying of the coupling agent on the end of the detection head 204. At the same time, through the rotation of the rotating pipe 205, the iris mechanism 206 rotates and opens. Further, when the detection head 204 continues to advance towards the pier column, after pushing the first slider 301 to the uppermost position, it will push the auxiliary rod 300 to rotate until the detection head 204 extends outside the detection pipe 200 and fits tightly against the surface of the pier column. Ultrasonic signals are simultaneously emitted and received by the two detection heads 204 on both sides, so as to perform ultrasonic detection on the inside of the pier column.

[0056] It should be noted that the detection head 204 is preferably a waterproof ultrasonic transducer in the prior art. The two 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 column.

[0057] It should be noted that one end of the auxiliary rod 300 away from the first slider 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 upward and contacts the second slider 309 and then continues to move upward, 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 forces of the torsion spring 302 and the first spring 211, so that during the process that the detection head 204 pushes the auxiliary rod 300 and the first slider 301 to move upward and compress the first spring 211, the auxiliary rod 300 can be kept parallel to the end of the detection head 204 by magnetic force. With the design of the second slider 309 and the roller at its bottom, there is a certain distance between the auxiliary rod 300 and the detection head 204, so that the coupling agent smoothly ejected 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, during the process of the detection head 204 retracting into the detection tube 200, the ball 209 resets along the driving groove 208. First, it passes through the straight part of the driving groove 208, then through the spiral part of the driving groove 208, and further through the straight part at the other end of the driving groove 208 to complete the reset. During this process, when the detection head 204 retracts past the auxiliary rod 300, under the elastic reset action of the torsion spring 302, the auxiliary rod 300 rotates and resets. 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. When it contacts the second slider 309, it then contacts the side wall of the second slider 309 and pushes the second slider 309 in the direction of the first slider 301. At this time, referring to Figure 10 , the auxiliary rod 300 is magnetically adsorbed on the top of the detection head 204 through the magnetism at the end of the auxiliary rod 300. During the reset process of the detection head 204, when the rotation tube 205 and the auxiliary rod 300 are driven to rotate in the reverse direction through the cooperation of the ball 209 and the driving groove 208, the auxiliary rod 300 can be driven to rotate one week along the end of the detection head 204, and the coupling agent remaining at the end of the detection head 204 is scraped and cleaned by the scraping blade 320. As the detection head 204 continues to retract and reset, when the auxiliary rod 300 rotates to be inclined towards the direction of the detection head 204 under the elastic force of the torsion spring 302, referring to Figure 11-13 , through the cooperation of the convex block 319 and the second push rod 318, when the auxiliary rod 300 rotates to the second push rod 318 passes through the convex block 319, the second push rod 318 is pushed into the limiting groove 317. Through the arc design at the bottom of the limiting groove 317 and the arc design at the top of the fourth slider 321, the fourth slider 321 can be pushed away from the clamping of the limiting groove 317, so that the third slider 311 resets under the elastic force of the second spring 313, and the coupling agent residue on the surface of the scraping blade 320 is pushed away and cleaned, so that the cleaned coupling agent residue is discharged through the sleeve 310 under the action of gravity, realizing the automatic cleaning of the scraping blade 320.

[0059] It should be noted that during the process of the detection head 204 detecting and extending to drive the auxiliary rod 300 to rotate upward, the rotation of the auxiliary rod 300 drives the first gear 315 to rotate. The first gear 315 drives the second gear 316 and the winding roller 312 to rotate more turns through meshing, tightens and winds the pull rope 314, and compresses the second spring 313 until the auxiliary rod 300 rotates to the highest point. At this time, the fourth slider 321 inside the third slider 311 is elastically clamped with the limiting groove 317, realizing the fixation and energy storage of the third slider 311. Until the detection head 204 completes the reset and the scraping blade 320 completes the cleaning work, after the auxiliary rod 300 rotates to the lowest point, the release of the third slider 311 and the cleaning of the scraping blade 320 are realized through the cooperation of the convex block 319 and the second push rod 318.

[0060] It should be noted that during the process of the detection head 204 driving the first slider 301 to rise to the highest position, through the pushing of the auxiliary rod 300 on the first push rod 306, the first push rod 306 applies a thrust to the sleeve 310, and the spring between the sleeve 310 and the first push rod 306 is also compressed. When the first slider 301 moves to the highest position, under the elastic force of the spring between the first push rod 306 and the sleeve 310, the sleeve 310 extends out and engages with the corresponding winding roller 312, realizing the fixation of the first slider 301. Only when the detection head 204 is reset, when the end of the detection head 204 passes by the auxiliary rod 300, after the auxiliary rod 300 rotates and resets to disengage from pushing the first push rod 306, under the elastic force of the spring between the first push rod 306 and the first slider 301, it drives the sleeve 310 to retract and disengage from the engagement of the clamping groove 212, realizing that during the reset process of the detection head 204, the auxiliary rod 300 synchronously resets with the end of the detection head 204, achieving a synchronous cleaning effect on the end of the detection head 204.

[0061] It should be noted that during the reset process of the detection head 204, when the detection head 204 pushes the second slider 309 to move towards the first slider 301, although the first pipeline 304 and the second pipeline 305 are connected at this time, since the distance between the blocking block 308 and the second slider 309 becomes larger and the magnetic attraction force between them becomes smaller, the blocking block 308 rises under the elastic force of the spring between it and the communication groove 307, blocking the connection between the discharge hole 303 and the first pipeline 304 to prevent the coupling agent from being discharged during reset.

[0062] When the frame 100 climbs downward to detect the lower part, only need to control the second motor 201 to move to the lower part, and at the same time, correspondingly rotate the rotating base 202 and the detection pipe 200, and adjust the detection head 204 to face the direction of the pier column, then the detection of the pier column in the downward movement direction can be realized. By adjusting the detection position of the detection pipe 200, the detection range during the movement of the frame 100 can be expanded.

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

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