Description

Technical Field

[0001] This invention relates to the field of bridge inspection technology, specifically to a high-efficiency underwater condition detection device for bridge piers. Background Technology

[0002] Bridges can be broadly categorized into superstructure, substructure, and ancillary structures. In beam bridges, the superstructure primarily refers to the main beams; the substructure includes piers, abutments, foundations and pile caps, and piles; ancillary structures include bridge deck pavement, railings, and expansion joints. Each component has its own stress characteristics, and their defects also share some commonalities. If uncommon defects are observed, their causes should be carefully investigated. Inspection of the bridge superstructure includes assessing the concrete strength of hollow slab beams, the carbonation depth of the hollow slab beam concrete, and the condition and distribution of cracks in the beams. Inspection of the bridge substructure includes assessing the condition and distribution of cracks in piers and abutments, and examining the weathering, spalling, cracking, misalignment, settlement, and horizontal displacement or rotation of frame piers.

[0003] The underwater inspection of bridge piers is of paramount importance in bridge inspection. Because this part is hidden underwater, it is difficult to observe. Current inspection methods mainly rely on manual diving to take pictures or using ultrasonic probes for flaw detection. Divers have limited time for each underwater operation, resulting in low efficiency. In addition, each bridge has a large number of piers, so the entire inspection process is very long. Furthermore, the images taken by divers are not stable or complete enough. Summary of the Invention

[0018] In the transfer state: the third drive rod extends downward to push the lower clamping plate to rotate upward, so that the lower clamping plate clamps the bottom surface of the sealing track to clamp the sealing track; at the same time, the lower clamping plate pushes the abutment plate to move upward, the abutment plate and the unlocking plate move upward along the guide groove, and the unlocking plate abuts the locking component to unlock, so that the outward flipping component can drive the sealing track to rotate outward.

[0021] Furthermore, the interior of the inspection vessel is equipped with a connecting assembly, which includes a fourth drive rod, an extension plate, and a towing hook. The fourth drive rod is located on the inspection vessel, and its top end is vertically connected to the extension plate.

The inspection vessel can carry floating plates to install them on the outside of each pier one by one. After installation, the two sets of sealing tracks are closed. This can efficiently complete the inspection of multiple piers under a large bridge.

[0028] 5. The walking track has built-in wheels, which not only make the walking track move more smoothly up and down, but also support the walking track from the inside, so that the distance between the walking track and the bridge pier remains fixed. Attached Figure Description

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Example

[0045] To address the technical problems in the background section, the following efficient underwater condition detection device for bridge piers is provided:

[0046] Combination Figures 1-12As shown, the present invention provides an efficient underwater condition detection device for bridge piers, comprising a floating plate 8, which includes a central floating plate and side floating plates. The inner walls of the central floating plate are vertically connected to the two ends of the side floating plates, and the central floating plate is connected to the two sets of side floating plates in a U-shape. A first clamping assembly 2 is installed in the middle of the surface of the central floating plate, a set of central traction assemblies 3 is installed in the middle of the surface of each side floating plate, and an outward flipping assembly 4 is installed at the outer end of the surface of each side floating plate. A set of second clamping assemblies 5 is assembled and connected to each outward flipping assembly 4. The floating plate 8 is connected to the detection vessel in parallel with alternating soft and hard connections.

[0047] The bottom of the first clamping assembly 2 is detachably clamped with an inner semi-circular track 11, the bottom of the middle traction assembly 3 is connected to a side track 12, and each set of second clamping assemblies 5 is detachably connected with a set of sealing tracks 13. The two open ends of the inner semi-circular track 11 are connected to two sets of side tracks 12 by screws, and the outer ends of the two sets of side tracks 12 are detachably connected to the sealing tracks 13. The sealing tracks 13 are semi-circular. The inner semi-circular track 11, the two sets of side tracks 12, and the two sets of sealing tracks 13 form a ring-shaped walking track 1. The inner walls of the inner semi-circular track 11, the two sets of side tracks 12, and the two sets of sealing tracks 13 are all provided with walking wheels 14. The walking track 1 is placed at intervals on the outside of the pier, and the walking wheels 14 are attached to the outer wall of the pier. The bottom of the walking track 1 is equipped with a detection host.

[0048] In the detection state: the first clamping component 2 disengages from the inner semi-circular track 11, the second clamping component 5 disengages from the sealing track 13, the middle traction component 3 lowers the side track 12, so that the entire walking track 1 sinks into the water under its own weight, the walking track 1 moves downward along the pier, and the detection component moves along the walking track 1 to perform annular flaw detection on the outer wall of the pier.

[0049] In the transfer state: the first clamping component 2 clamps the inner semi-arc track 11, the middle traction component 3 pulls and lifts the sealing track 13, the second clamping component 5 clamps the sealing track 13, the two sets of outward flipping components 4 drive the two sets of second clamping components 5 to flip outward, so that the two sets of sealing tracks 13 rotate outward and open, and the quarter arc surface of the two sets of sealing tracks 13 faces inward. The area between the two sets of sealing tracks 13 is the pier entry and exit gap.

[0050] The above technical solution has the following effects:

[0051] I. The design of the walking track 1 has the following effects: 1. The walking track 1 can serve as a guiding structure for the underwater movement of the detection host, enabling it to accurately and equidistantly detect along the outer perimeter of the bridge pier without shifting with the water flow, thus improving the detection effect; 2. When the first clamping component 2 and the second clamping component 5 are unlocked, the central traction component 3 can lower the entire walking track 1, which will then slowly sink under its own weight, thereby driving the detection host to make a circular motion while sinking vertically, solving the drawbacks of previous manual underwater filming; 3. The walking track 1 is composed of multiple sections, and each section can be replaced with a suitable size according to the dimensions of the bridge section. 4. Two sets of symmetrically arranged sealing tracks 13 are designed. During inspection, they can be connected with other tracks to allow the main inspection unit 9b to move in a ring. During transfer, the two sets of sealing tracks 13 can be opened individually, thus forming a gap for the bridge section to enter and exit. The inspection vessel can carry the floating plate 8 to install on the outside of each pier one by one. After installation, the two sets of sealing tracks 13 are closed again. This can efficiently complete the inspection of multiple piers under a large bridge. 5. The walking track 1 has built-in walking wheels 14, which can make the walking track 1 move up and down more smoothly, and can also support the walking track 1 from the inside, so that the distance between the walking track 1 and the pier remains fixed.

[0052] Second, the floating plate 8 and the inspection vessel adopt a flexible and rigid connection method. When rigidly connected, the floating plate 8 can be rotated and assembled, and when flexiblely connected, it can meet the inspection requirements.

[0053] To enable the first clamping assembly 2 to achieve the aforementioned clamping, locking, and unlocking requirements of the inner semi-circular track 11, the following solution is provided:

[0054] In this embodiment, the first clamping assembly 2 includes a first column 21, a first top plate 22, and a first adjusting screw 23. The first column 21 is vertically disposed on the surface of the middle floating plate. The top of the first column 21 slides vertically through the first top plate 22. The top of the first column 21 is threaded vertically through the first adjusting screw 23. The first adjusting screw 23 is horizontally disposed below the first top plate 22. A vertical rod 24 is vertically disposed at the inner end of the bottom surface of the first top plate 22. The inner end of the first adjusting screw 23 is rotatably connected to the vertical rod 24. The bottom end of the vertical rod 24 is provided with an inverted U-shaped bracket 25. The bottom end of the bracket 25 is vertically provided with a support plate 251. The support plate 251 and the bracket 25 are arranged in an L-shape. The inner wall of the bracket 25 is provided with an outer clamping assembly 26.

[0055] The inner semi-circular track 11 is clamped within the area enclosed by the tray 251, the bracket 25, and the outer clamping assembly 26, with the top wheel on the inner wall of the inner semi-circular track positioned opposite each other within the opening of the bracket 25.

[0056] In this embodiment, the outer clamping assembly 26 includes an outer clamping rod 261 and a sliding rod 262; the sliding rod 262 is vertically fixedly connected to the top of the inner wall of the bracket 25, the outer clamping rod 261 is slidably fitted on the outer wall of the sliding rod 262, the top of the outer clamping rod 261 is connected to the first column 21 through a connecting arm, and the bottom of the outer clamping rod 261 is an outward arc-shaped structure.

[0057] In the above technical solution, rotating the first adjusting screw 23 inward can drive the first top plate 22 and the bracket 25 to move inward, increasing the distance between the bracket 25 and the outer clamping rod 261, and separating the support plate 251 from the inner arc-shaped track.

[0058] To enable the central traction assembly 3 to achieve the clamping, locking, and unlocking requirements of the opposite side rail 12, the following solution is proposed:

[0059] In this embodiment, the central traction assembly 3 includes a second column 31, which is vertically disposed on the surface of the side floating plate. A fixing plate 32 is provided at the top of the second column 31, and a winding wheel 33 is provided on the surface of the fixing plate 32. A second top plate 35 is vertically slidably passed through the top of the second column 31, and a second adjusting screw 36 is vertically threaded through it. The second adjusting screw 36 is disposed above the second top plate 35. A constraint plate 351 is vertically disposed on the surface of the second top plate 35, and the inner end of the second adjusting screw 36 is rotatably connected to the constraint plate. The top surface of the plate 351 and the constraint plate 351 are provided with a first guide ring 3511. The outer wall of the winding reel 33 is wound with a traction rope 34. The bottom surface of the second top plate 35 is vertically provided with a support rod 37. The bottom end of the support rod 37 is vertically provided with a horizontal second guide ring 371. The traction rope 34 passes through the first guide ring 3511, the second top end, and the second guide ring 371. The bottom end of the traction rope 34 is connected to a stud 341. The stud 341 is screwed into the middle of the top surface of the side track 12. The stud 341 and the second guide ring 371 are fitted together.

[0060] In the above technical solution:

[0061] 1. The design of the first guide ring 3511 and the second guide ring 371 can guide the release and retraction of the traction rope 34. At the same time, when the side rail 12 is in the lifted and retracted state, the stud 341 is embedded in the second guide ring 371. In this way, the second guide ring 371 constrains the stud 341 and thus constrains the side rail 12, so the side rail 12 can no longer shake.

[0062] 2. The rotation of the second screw can drive the second top plate 35 to extend and retract, thereby adjusting the distance between the side rail 12 and the pier, so that the side rail 12 can be placed close to the side of the pier; while moving, the position of the first guide ring 3511 also changes accordingly, ensuring the guide effect.

[0063] 3. When the motor drives the winding wheel 33 to rotate and release the traction rope 34, the side rail 12 can be lowered.

[0064] To enable the second clamping assembly 5 to achieve the aforementioned requirements for clamping, locking, and unlocking the sealing track 13, the following solution is provided:

[0065] In this embodiment, the second clamping assembly 5 includes a main support plate 51, the outer end of which is connected to the outward flipping assembly 4. A movable telescopic section 511 is provided in the middle of the main support plate 51. A clamping column 53 is rotatably installed on the inner end of the bottom surface of the main support plate 51. A second motor 52 for driving the clamping column 53 to rotate is installed on the surface of the main support plate 51. The second motor 52 is used to adjust the sealing track 13 to face inward with a quarter arc surface. An upper clamping plate 531 is provided in the middle of the outer wall of the clamping column 53. The upper clamping plate 531 clamps the top surface of the sealing track 13. A third drive rod 532 is installed inside the clamping column 53. An adjusting plate 533 is provided at the bottom end of the third drive rod 532. The adjusting plate 533 is meshed with a flipping gear 541. The flipping gear 541 is rotatably installed at the bottom end of the inside of the clamping column 53. The flipping gear 541 is fixedly connected to the lower clamping plate 54.

[0066] In the above technical solution:

[0067] 1. The main support plate 51 and the clamping column 53 form a swing arm structure. The outward flipping component 4 drives the swing arm structure to drive the entire sealing track 13 to flip outward significantly.

[0068] 2. When the third drive rod 532 extends downward, it pushes the adjusting plate 533 to move downward. The adjusting plate 533 drives the flipping gear 541 to rotate. The flipping gear 541 drives the lower clamping plate 54 to flip upward and clamp the sealing track 13.

[0069] 3. The second motor 52 can fine-tune the position of the sealing track 13 a second time, based on the first drive of the outward flipping component 4 to flip the sealing track 13 outward, so that the quarter arc surface faces inward. In this way, when the floating plate 8 is adjusted and the open state walking track 1 enters the outside of the pier, the arc of the pier and the sealing track 13 make contact, allowing the pier to smoothly enter the walking track 1. At the same time, the middle part of the main support plate 51 is designed as a movable telescopic section 511, so that the guide structure becomes a flexible guide structure. When the sealing track 13 comes into contact with the pier, the movable telescopic section 511 moves elastically to avoid hard contact and collision.

[0070] The design of the clamping and locking structure for the sealing track 13 needs to address the following issues: 1. The sealing track 13 needs to be detachably connected to the side track 12, and the disassembly operation cannot be performed by workers; 2. The sealing assembly needs to be able to sink normally, and the unlocking structure should not interfere; 3. The sealing assembly needs to remain clamped when rotating outwards. To solve the above problems, the following solutions are proposed:

[0071] In this embodiment, the lower clamping plate 54 is provided with an abutment plate 55 on its side, the side wall of the clamping column 53 is provided with a guide plate 57, the guide plate 57 is provided with a guide groove 571 inside, a moving column is slidably installed inside the guide groove 571, the inner end of the moving column is vertically connected to an abutment rod 56, the abutment rod 56 extends vertically downward, the bottom end of the abutment plate 55 is arc-shaped, the outer end of the moving column is provided with an unlocking plate 58 vertically, the unlocking plate 58 extends horizontally outward from the guide plate 57; the top of the sealing track 13 is provided with a locking assembly 6.

[0072] Under testing conditions: the lower clamping plate 54 is in a vertical position, the locking assembly 6 connects the sealing track 13 and the side track 12 into one unit, and the sealing track can be lowered normally;

[0073] In the transfer state: the third drive rod 532 extends downward to push the lower clamping plate 54 to rotate upward, so that the lower clamping plate 54 clamps the bottom surface of the sealing track 13 to clamp the sealing track 13; at the same time, the lower clamping plate 54 pushes the abutment plate 55 to move upward, the abutment plate 55 and the unlocking plate 58 move upward along the guide groove 571, and the unlocking plate 58 abuts the locking component 6 to unlock, so that the outward flipping component 4 can drive the sealing track 13 to rotate outward.

[0074] In the above technical solution, during the flipping process of the lower clamping plate 54, the abutment plate 55 can simultaneously push the abutment rod 56, thereby pushing the moving column to move along the guide groove 571. The unlocking plate 58 moves upward at an angle, thereby lifting the locking component 6 and realizing unlocking. The whole process is synchronized with the clamping process. While clamping is achieved, the sealing track 13 will separate from the side track 12. Subsequently, the sealing track 13 can be moved directly without waiting, resulting in higher unlocking efficiency. When the lower clamping plate 54 moves downward, the unlocking plate 58 no longer abuts the locking component 6, and the locking component 6 can lock again.

[0075] The unlocking plate 58 is unlocked by tilting upward, which allows the unlocking plate 58 to be misaligned to the side in the detection state, and it will not block the synchronous downward movement of the locking component 6 and the sealing track 13.

[0076] In this embodiment, the locking assembly 6 includes a vertical post 61, a horizontal post 62, a second spring rod 63, and a locking post 64. The horizontal post 62 is located above the sealing track 13. The bottom surface of the horizontal post 62 is vertically spaced with the locking post 64 and the second spring rod 63. The second spring rod 63 is located on the top surface of the sealing track 13. The inner end of the horizontal post 62 is vertically spaced with a downwardly extending vertical post 61. The vertical posts 61 are spaced apart on the inner side of the sealing track 13, and they engage with the unlocking plate 58. When the unlocking plate 58 engages with the vertical post 61, it causes the horizontal post 62 to move upward, which in turn causes the locking post 64 to move upward to unlock the track, and the second spring rod 63 is stretched.

[0077] To enable the sealing track 13 to automatically flip outward to the appropriate position, this embodiment provides the following solution:

[0078] The outward-turning assembly 4 includes a base plate 41. A first drive rod 42 is fixed to the inner side of the surface of the base plate 41. The output end of the first drive rod 42 is vertically fixed to a push plate 43. A center block 44 is slidably installed on the outer side of the push plate 43. The side wall of the push plate 43 is connected to a second drive rod 46 through a connecting plate 45. A longitudinal groove 411, a transverse groove 412, and a circular groove 413 are integrally formed on the outer end of the surface of the base plate 41. The longitudinal groove 411 is located inside the transverse groove 412. The longitudinal groove 411 and the transverse groove 412 are connected in an L-shape. The outer end of the transverse groove 412 is connected to the circular groove 413. A turntable 48 is rotatably embedded inside the circular groove 413. The turntable 48 has a U-shaped receiving groove 481 inside, and a first motor 49 for driving the turntable 48 to rotate is installed on the bottom surface of the base plate 41. The center block 44 has a vertically arranged swing column 47 inside, and a moving block 441 is provided at the bottom end of the swing column 47. The first drive rod 42 pushes the center block 44 to move, and the moving block 441 moves along the longitudinal groove 411, so that the sealing track 13 is longitudinally separated from the side track 12. The second drive rod 46 drives the moving block 441 to move along the transverse groove 412 to the receiving groove 481. The rotation of the turntable 48 can drive the sealing track 13 to rotate outward to form a gap for the bridge pier to enter and exit.

[0079] In the above technical solution, the eversion process is designed into three stages:

[0080] In the first stage, the first drive rod 42 pushes the center block 44 to move, and the moving block 441 moves along the longitudinal groove 411, so that the sealing track 13 is longitudinally separated from the side track 12.

[0081] In the second stage, the second drive rod 46 drives the center block 44 to move laterally along the push plate 43, so that the moving block 441 enters the transverse groove 412, causing the sealing track 13 to expand to both sides.

[0082] In the third stage, the moving block 441 moves into the receiving groove 481, the first motor 49 drives the turntable 48 to rotate, which in turn drives the moving block 441 to rotate, the moving block 441 drives the swing column 47 to rotate, which in turn drives the sealing track 13 to rotate.

[0083] The entire unlocking process is more continuous and efficient, eliminating the need for separate steps.

[0084] In this embodiment, a connecting assembly 7 is installed inside the inspection vessel. The connecting assembly 7 includes a fourth drive rod 71, an extension plate 72, and a traction hook 73. The fourth drive rod 71 is located on the inspection vessel, and its top end is vertically connected to the extension plate 72. The traction hook 73 is vertically provided at the outer end of the bottom surface of the extension plate 72. In the transfer state, the traction hook 73 is fitted into the stop groove 512 of the main support plate 51. The side walls of the inspection vessel are connected to the side floats via multiple soft ropes 9a. The traction hook 73 can drive the floats 8 to follow the movement. The traction hook 73 can be directly fitted onto the main support plate 51, and then it can be pulled against the surface. The operation is simple. The inspection vessel's prow is connected in parallel with the opening of the travel track 1, which facilitates control and adjustment.

[0085] Working principle and usage process of this invention:

[0086] S1. The floating plate 8 is placed on the outside of the pier, the walking track 1 is placed on the water surface, and each walking wheel 14 is attached to the outer wall of the pier; the protruding column of the inner semi-circular track 11 is inserted into the left and right side tracks 12, and then screws are tightened: the two sealing tracks 13 are connected to each other, and each sealing track 13 is inserted into the side track 12. The locking component 6 is inserted and positioned at the connection between the sealing track 13 and the side track 12.

[0087] S2, the first clamping assembly 2 and the second clamping assembly 5 are unlocked, the winding wheel 33 releases the traction rope 34, so that the traveling track 1 sinks into the water under the action of gravity, the traveling wheel 14 rolls along the outer wall of the pier, and the detection host 9b makes a circular motion along the traveling track 1, thereby taking a comprehensive picture of the underwater part of the pier and performing ultrasonic flaw detection; the detected data is transmitted to the detection vessel 9 in real time.

[0088] S3. After the inspection is completed, the central traction component 3 drives the walking track 1 to the water surface, the first clamping component 2 clamps the inner semi-circular track 11, the second clamping component 5 clamps the sealing track 13, and the locking component 6 unlocks.

[0089] S4. The outward turning process is divided into three stages: In the first stage, the first drive rod 42 pushes the center block 44 to move, and the moving block 441 moves along the longitudinal groove 411, so that the sealing track 13 is longitudinally separated from the side track 12; In the second stage, the second drive rod 46 drives the center block 44 to move laterally along the push plate 43, so that the moving block 441 enters the transverse groove 412, and the sealing track 13 expands to both sides; In the third stage, the moving block 441 moves into the receiving groove 481, the first motor 49 drives the turntable 48 to rotate, which in turn drives the moving block 441 to rotate, and the moving block 441 drives the swing column 47 to rotate, which in turn drives the sealing track 13 to rotate.

[0090] S5. The second motor 52 drives the clamping column 53 to rotate, adjusting the position of the sealing track 13 so that the arc surface of the sealing track 13 faces inward, forming a guide structure.

[0091] S6. The traction hook 73 of the inspection vessel is connected to the main support plate 51. The inspection vessel drives the floating plate 8 to exit the inspected pier, and then drives the floating plate 8 to align with the next pier. The pier entry and exit gap of the travel track 1 is aligned with the pier. Then the travel track 1 gradually moves to the outside of the pier. Under the action of the pier entry guide structure, the pier smoothly enters the travel track 1, and the traction hook 73 is disengaged from the main support plate 51.
