Currently, most ring-shaped flaw detection devices for steel piers use a crawling chassis as the moving platform. However, the rolling motion of this crawling chassis on the steel pier causes vibration to the flaw detection device, thus affecting the accuracy of the flaw detection. This invention addresses the technical problem of vibration impact on flaw detection devices caused by using a pier-mounted crawling chassis as the moving platform, by employing a crawling feature that eliminates vibration energy carried over during movement on steel piers.

[0042] This invention designs a method for annular flaw detection of steel piers in a stable motion state. The steps are as follows: the detection upper assembly is installed on a double-moving trolley, the double-moving trolley moves on the steel pier in a buffered contact state, and the thrust telescopic cylinder provides the power drive for the double-moving trolley, thus achieving the use of crawling to carry away vibration energy generated during movement on the steel pier.

[0043] The technical effects of the above solutions are: highlighting the technical feature of eliminating the creeping carryover of vibration energy generated during movement on steel piers, and introducing its application in the technical field of ring flaw detection methods for steel piers in a stable motion state.

[0044] The present invention is designed with the following steps: When annular flaw detection is required on a steel pier, the adsorption block is energized and magnetic. Two ring parts I for mounting the upper split ring disc and two ring parts I for mounting the lower split ring disc are placed on the steel pier. Under the action of spring part I, the contact wheel is placed on the steel pier, causing the swing telescopic cylinder to extend. This causes the lower ends of the outer swing support rod part III and the outer swing support rod part IV to swing inward on the annular groove of the intermediate shaft part I, causing the adsorption block to act on the steel pier. Under the elastic energy storage action of spring part II, the moving rod part II moves within the cylinder, causing the adsorption block to adhere to the steel pier. This aligns the corresponding two ear parts I on the upper split ring disc, allowing the adsorption block to adhere to the steel pier. Align the corresponding lug parts II on the upper split ring plate, align the two corresponding lug parts I on the lower split ring plate, and align the corresponding lug parts II on the lower split ring plate. Place the intermediate connecting bolt and nut into the through holes of lug parts I and II respectively, and rotate the intermediate connecting bolt and nut on the bolt. The bolt flange and nut of the intermediate connecting bolt and nut act on the outer side of lug part I and the outer side of lug part II respectively, so that the sides of the corresponding buffer block extensions are in contact. This completes the docking of the two ring parts I on the upper split ring plate and the two ring parts I on the lower split ring plate on the steel pier column. This allows the upper and lower split-type ring discs to be installed on the steel pier, so that the adsorption block on the upper split-type ring disc is in a de-energized and non-magnetic state, and the swing telescopic cylinder on the upper split-type ring disc is in a retracted state. This causes the lower ends of the outer swing support rod III and the lower ends of the outer swing support rod IV to swing outward on the annular groove of the intermediate shaft I. The adsorption block on the upper split-type ring disc separates from the steel pier, and the thrust telescopic cylinder is in an extended state, causing the ring I on the upper split-type ring disc to move upward. The receiving hole II moves upward on the guide rod, and the contact wheel on the upper split-type ring disc moves upward on the steel pier. When the extension of the guide rod is close to the outer end of the ring I on the upper split-type ring disc... When the outer surface contacts the steel pier, the thrust telescopic cylinder stops extending, the swing telescopic cylinder on the upper split ring disk extends, the adsorption block on the upper split ring disk becomes electrically charged and magnetic, the adsorption block on the upper split ring disk adheres to the steel pier, the adsorption block on the lower split ring disk becomes de-charged and non-magnetic, the swing telescopic cylinder on the lower split ring disk retracts, causing the lower ends of the outer swing support rod III and the outer swing support rod IV to swing outwards on the annular groove of the intermediate shaft I, separating the adsorption block on the lower split ring disk from the steel pier, the thrust telescopic cylinder retracts, and the ring I on the lower split ring disk moves upwards.The receiving hole II moves downward on the guide rod, while the contact wheel on the lower split ring disc moves upward on the steel pier. After the retraction of the thrust telescopic cylinder is completed, the swing telescopic cylinder on the lower split ring disc is in the extended state, causing the adsorption block on the lower split ring disc to become electrically charged and magnetic. The adsorption block on the lower split ring disc adheres to the steel pier, thus realizing the climbing motion of the upper and lower split ring discs on the steel pier, causing the lower split ring disc to... The adsorption block on the split ring disk is de-energized and non-magnetic, causing the swing telescopic cylinder on the lower split ring disk to retract. This causes the lower ends of the outer swing support rods III and IV to swing outward on the annular groove of the intermediate shaft I, separating the adsorption block on the lower split ring disk from the steel pier. This causes the thrust telescopic cylinder to extend, moving the ring I on the lower split ring disk downward, and causing the receiving hole II to move upward on the guide rod. The contact wheel on the lower split ring plate moves downwards on the steel pier. When the extended part of the guide rod contacts the outer side of the outer end face of ring I on the upper split ring plate, the thrust telescopic cylinder stops extending, the swing telescopic cylinder on the lower split ring plate is in the extended state, the adsorption block on the lower split ring plate is in an electrically charged and magnetic state, the adsorption block on the lower split ring plate is adsorbed onto the steel pier, and the adsorption block on the upper split ring plate is de-energized. In a non-magnetic state, the swing telescopic cylinder located on the upper split ring disk is in a retracted state, causing the lower ends of the outer swing support rod III and the outer swing support rod IV to swing outward on the annular groove of the intermediate shaft I. The adsorption block on the upper split ring disk separates from the steel pier, causing the thrust telescopic cylinder to retract, causing the ring I on the upper split ring disk to move downward. The receiving hole II moves downward on the guide rod, and the contact wheel on the upper split ring disk... The device moves downwards on the steel pier. After the thrust telescopic cylinder retracts, the swing telescopic cylinder on the upper split ring disc extends, causing the adsorption block on the upper split ring disc to become electrically charged and magnetic. This allows the adsorption block to adhere to the steel pier, thus enabling the upper and lower split ring discs to descend on the steel pier. When the motor is in operation, the end of the gear rotates within the rotating hole of the moving seat. Through the meshing transmission between the gear and ring II, the moving seat moves on ring II. The moving seat then drives the ultrasonic transmitter and receiver of the flaw detection component to move in an arc. When performing annular flaw detection on a section of the steel pier, the upper and lower split ring disks are positioned on the section of the steel pier, causing the adsorption blocks on the upper and lower split ring disks to simultaneously adhere to the steel pier.The ultrasonic transmitter and receiver of the flaw detection component move in a corresponding arc shape on one section of the steel pier. The ultrasonic transmitter releases detection ultrasonic waves, which act on one side of the steel pier section. The ultrasonic receiver receives the penetrating ultrasonic waves on the other side of the steel pier section, thus performing flaw detection on the steel pier. After completing the annular flaw detection, the bolts of the intermediate connecting bolt and nut are removed from the through holes of the lug part I and lug part II, respectively. This separates the two ring parts I on the upper and lower split ring disks on the steel pier, de-energizing the adsorption block and separating the ring parts I from the steel pier.

[0045] The technical effect of the above solution is that it enables motion support operation on steel piers by using springs as vibration damping.

[0046] In this technical solution, the thrust telescopic cylinder is the basic component and an essential technical feature of the invention. The upper split ring disc, the lower split ring disc, the guide rod, the follower wheel, the swing frame, the swing telescopic cylinder, the suction claw, the ring cart, the buffer block, and the flaw detection component are functional components, features that achieve other technical effects of the invention. The design of the ring part I, ear part I, ear part II, ear part III, receiving hole I, receiving hole II, receiving hole III, moving rod part I, spring part I, outer swing support rod part I, outer swing support rod part II, intermediate shaft part I, contact wheel part, outer swing support rod part III, outer swing support rod part IV, intermediate shaft part II, cylinder part, moving rod part II, spring part II, support seat, suction block, ring part II, moving seat part, gear part, and motor part are technical features that comply with the Patent Law and its implementing regulations.

[0047] In this technical solution, the crawling mechanism that eliminates vibration energy generated during movement on the steel pier is achieved by a double-moving disc carriage and a thrust telescopic cylinder.

[0048] In this technical solution, the key technical features are the use of a crawling-carried detection upper assembly, a dual-moving disc carriage, and a thrust telescopic cylinder to eliminate vibration energy generated during movement on the steel pier. In the technical field of ring flaw detection devices and methods for steel piers in a stable motion state, this solution is novel, inventive, and practical.

[0088] The present invention will be further described below with reference to embodiments. These embodiments are intended to illustrate the present invention and not to further limit the present invention.

[0089] A method for annular flaw detection of steel piers in a stable motion state includes the following steps: When annular flaw detection of the steel pier is required, the adsorption block 85 is energized and magnetic. Two ring parts I11 for mounting the upper split ring disk 1 and two ring parts I11 for mounting the lower split ring disk 2 are placed on the steel pier. Under the action of the spring part I52, the contact wheel part 56 is placed on the steel pier, causing the swing telescopic cylinder 7 to extend. This causes the lower ends of the outer swing support rod part III61 and the outer swing support rod part IV62 to swing inward on the annular groove of the intermediate shaft part I55, causing the adsorption block 85 to act on the steel pier. Under the elastic energy storage action of the spring part II83, the moving rod part II82 moves within the cylinder part 81, causing the adsorption block 85 to adhere to the steel pier. This aligns the corresponding two ear parts I12 on the upper split ring disk 1, ensuring that the upper split ring disk 1 is properly aligned. Align the corresponding lug portions II13 on the split ring disc 1, align the corresponding two lug portions I12 on the lower split ring disc 2, and align the corresponding lug portions II13 on the lower split ring disc 2. Place the intermediate connecting bolt and nut into the through holes of lug portions I12 and II13 respectively, and rotate the intermediate connecting bolt and nut on the bolt. The bolt flange and the nut of the intermediate connecting bolt and nut act on the outer side of lug portion I12 and the outer side of lug portion II13 respectively, so that the sides of the extension portions of the corresponding buffer blocks 91 are in contact. This completes the docking of the two ring portions I11 on the upper split ring disc 1 and the two ring portions I11 on the lower split ring disc 2 on the steel pier column, thus realizing the installation of the upper split ring disc 1 and the lower split ring disc 2 on the steel pier column. The adsorption block 85 on the upper split ring disk 1 is de-energized and non-magnetic, and the swing telescopic cylinder 7 on the upper split ring disk 1 is in a retracted state. This causes the lower ends of the outer swing support rod III 61 and the outer swing support rod IV 62 to swing outward on the annular groove of the intermediate shaft I 55. The adsorption block 85 on the upper split ring disk 1 separates from the steel pier, and the thrust telescopic cylinder 3 is in an extended state. This causes the ring I 11 on the upper split ring disk 1 to move upward, accommodating the hole II. 16. The guide rod 4 moves upward, and the contact wheel 56 on the upper split ring disk 1 moves upward on the steel pier. When the extension of the guide rod 4 contacts the outer side of the outer end face of the ring part I11 on the upper split ring disk 1, the thrust telescopic cylinder 3 is stopped from extending, the swing telescopic cylinder 7 on the upper split ring disk 1 is extended, and the adsorption block 85 on the upper split ring disk 1 is in a state of being electrically charged and magnetic, so that the adsorption block 85 on the upper split ring disk 1 is adsorbed onto the steel pier. On the column, the adsorption block 85 located on the lower split ring disk 2 is de-energized and non-magnetic, and the swing telescopic cylinder 7 located on the lower split ring disk 2 is in a retracted state. This causes the lower ends of the outer swing support rod III 61 and the outer swing support rod IV 62 to swing outward on the annular groove of the intermediate shaft I 55, separating the adsorption block 85 located on the lower split ring disk 2 from the steel pier column. This causes the thrust telescopic cylinder 3 to be in a retracted state, causing the ring I 11 located on the lower split ring disk 2 to move upward. The perforated body II 16 moves downward on the guide rod 4, while the contact wheel 56 on the lower split ring disk 2 moves upward on the steel pier. After the thrust telescopic cylinder 3 completes its retraction, the swing telescopic cylinder 7 on the lower split ring disk 2 is extended, causing the adsorption block 85 on the lower split ring disk 2 to become electrically magnetic. The adsorption block 85 on the lower split ring disk 2 then adheres to the steel pier, thus enabling the upper split ring disk 1 and the lower split ring disk 2 to climb on the steel pier. The adsorption block 85 on the lower split ring disk 2 is de-energized and non-magnetic, and the swing telescopic cylinder 7 on the lower split ring disk 2 is in a retracted state. This causes the lower ends of the outer swing support rod III 61 and the outer swing support rod IV 62 to swing outward on the annular groove of the intermediate shaft I 55, separating the adsorption block 85 on the lower split ring disk 2 from the steel pier. This causes the thrust telescopic cylinder 3 to extend, causing the ring I 11 on the lower split ring disk 2 to move downward, and the receiving hole II 16 to move upward on the guide rod 4. The contact wheel 56 on the lower split ring disk 2 moves downward on the steel pier. When the extended part of the guide rod 4 contacts the outer side of the outer end face of the ring part I11 on the upper split ring disk 1, the thrust telescopic cylinder 3 stops extending, the swing telescopic cylinder 7 on the lower split ring disk 2 is in the extended state, the adsorption block 85 on the lower split ring disk 2 is in the energized and magnetic state, the adsorption block 85 on the lower split ring disk 2 is adsorbed onto the steel pier, the adsorption block 85 on the upper split ring disk 1 is in the de-energized and non-magnetic state, the swing telescopic cylinder 7 on the upper split ring disk 1 is in the retracted state, driving the lower end of the outer swing support rod part III61 and the lower end of the outer swing support rod part IV62 to the intermediate shaft part I55. The upper split ring disc 1 swings outward on the annular groove, causing the adsorption block 85 on the upper split ring disc 1 to separate from the steel pier column, thus retracting the thrust telescopic cylinder 3. This causes the ring part I 11 on the upper split ring disc 1 to move downward, and the receiving hole II 16 to move downward on the guide rod 4. The contact wheel part 56 on the upper split ring disc 1 moves downward on the steel pier column. After the thrust telescopic cylinder 3 completes its retraction, the swing telescopic cylinder 7 on the upper split ring disc 1 extends, causing the adsorption block 85 on the upper split ring disc 1 to become electrically magnetic, thus adsorbing the adsorption block 85 on the upper split ring disc 1 onto the steel pier column. This achieves the downward movement of the upper split ring disc 1 and the lower split ring disc 2 on the steel pier column. When the motor unit 96 is in operation, the end of the gear unit 97 rotates in the rotating hole of the movable seat unit 98. Through the meshing transmission between the teeth of the gear unit 97 and the ring unit II 99, the movable seat unit 98 is driven to move on the ring unit II 99. The movable seat unit 98 drives the ultrasonic transmitter head and the ultrasonic receiver head of the flaw detection component 92 to perform arc-shaped movements. When performing annular flaw detection on a section of a steel pier, the upper split annular disk 1 and the lower split annular disk 2 are positioned on the section of the steel pier. The adsorption blocks 85 on both the upper and lower split annular disks simultaneously adhere to the steel pier. The ultrasonic transmitter and receiver of the flaw detection component 92 then perform corresponding arc-shaped movements on this section of the steel pier. The ultrasonic transmitter of the flaw detection component 92 releases detection ultrasonic waves, which act on one side of the section of the steel pier. The ultrasonic receiver of the flaw detection component 92 receives the penetrating ultrasonic waves on the other side of the section of the steel pier, thus achieving flaw detection of the steel pier. After completing the annular flaw detection of the steel pier, the bolts of the intermediate connecting bolts and nuts are removed from the through holes of the lug part I12 and the lug part II13, respectively. This separates the two ring parts I11 on the upper split ring disk 1 and the two ring parts I11 on the lower split ring disk 2 on the steel pier, and puts the adsorption block 85 in a de-energized and non-magnetic state, thus separating the ring parts I11 from the steel pier.

[0090] In verifying this invention, the inventors abandoned the existing technical features that use a pier-crawling chassis as the moving chassis, which would cause vibration to the flaw detection device. Instead, they first proposed a crawling feature that eliminates vibration energy generated during movement on the steel pier, resulting in the first unexpected technical effect: enabling fan-shaped flaw detection on the steel pier, achieving full lateral coverage of the steel pier, and improving the reliability of flaw detection on the steel pier. The second unexpected technical effect was achieved: enabling flaw detection on the steel pier using the ring-shaped vehicle 9 and the flaw detection component 92, and enabling flaw detection on the steel pier itself. The segmented flaw detection method improved the efficiency of flaw detection on steel piers, resulting in a third unexpected technical effect: It enabled the crawling motion support of the annular vehicle 9 via the upper split annular disc 1, lower split annular disc 2, thrust telescopic cylinder 3, follower wheel 5, swing frame 6, swing telescopic cylinder 7, and suction claw 8, allowing for omnidirectional ultrasonic scanning on the steel piers. This resulted in a fourth unexpected technical effect: It enabled the guiding motion between the upper and lower split annular discs 1 and 2 via the guide rod 4, preventing deviations in the crawling trajectory on the steel piers. This resulted in a fifth unexpected technical effect: By using buffer block 91 to pad the ring I11, impact forces are prevented on guide rod 4, follower wheel 5, and adsorption claw 8, resulting in a sixth unexpected technical effect: contact with the steel pier column is achieved through moving rod I51, spring I52, outward swing support rod I53, outward swing support rod II54, and contact wheel 56, improving the smoothness of contact wheel 56's movement, resulting in a seventh unexpected technical effect: electromagnetic adsorption of the steel pier column is achieved through cylinder 81, moving rod II82, spring II83, support seat 84, and adsorption block 85, extending the lifespan of adsorption block 85. The service life was extended, resulting in the eighth unexpected technical effect: the ultrasonic transmitter and receiver of the flaw detection component 92 were driven to perform semi-circular motion by the ring part II 99, the moving seat part 98, the gear part 97, and the motor part 96, respectively, which improved the correspondence between the ultrasonic transmitter and receiver of the flaw detection component 92. This resulted in the ninth unexpected technical effect: the use of the pier climbing chassis as the motion chassis was no longer the sole method, which enhanced the adsorption force of the crawling motion on the steel pier and improved the stability of the flaw detection component 92 in its service life on the steel pier.

[0101] 5. Due to the design of buffer block 91, the buffer body docking connection between the upper split ring disk 1 and the lower split ring disk 2 is realized.
