Description

Technical Field

[0001] The invention relates to the technical field of road and bridge detection, and in particular to a mobile road and bridge nondestructive detection detector. Background Art

[0002] The application research of non-destructive testing technology in road engineering has far-reaching significance. With the rapid development of transportation infrastructure, the quality and safety of road engineering have received increasing attention. As a non-destructive evaluation method, non-destructive testing technology can evaluate its internal defects, damage and performance without destroying the material or structure, providing an important basis for the maintenance, repair and reconstruction of road engineering. Through the application of non-destructive testing technology, potential problems in road engineering can be discovered in time, accidents can be avoided, and traffic safety and smoothness can be ensured. In addition, non-destructive testing technology can also improve the quality and durability of road engineering, extend its service life, and reduce the frequency and cost of maintenance and reconstruction.

[0003] However, there are usually some problems with ordinary mobile road and bridge nondestructive testing detectors during daily use. With the development of science and technology, technicians in related fields have also made a lot of optimizations on mobile road and bridge nondestructive testing detectors to solve some problems that different consumer groups care about. In order to make a more accurate comparison, a Chinese patent with publication number CN212363071U discloses a mobile urban road bridge detection device. The above-mentioned prior art relates to the technical field of bridge and road detection devices. The mobile urban road bridge detection device includes a horizontal plate and a detection mechanism. The upper surface of the horizontal plate has two parallel grooves on the left and right, and The detection mechanism is provided with two and vertically penetrates the two slots; the front and rear sides of the upper surface of the horizontal plate are provided with slide grooves, and the slide grooves are parallel to the front and rear sides of the slots; the detection mechanism includes a support plate, a pull rod and a sliding rod, and two pull rods are provided and horizontally welded to the middle position of the front and rear sides of the support plate, two sliding rods are provided and vertically welded downward to the front and rear sides of the lower surface of the support plate, the two sliding rods correspond to the two slide grooves up and down, and the ends of the sliding rods slide into the slide grooves and are slidably connected thereto; the detection mechanism also includes a vertical plate, a bottom plate, a vertical plate, a connecting block, a round rod and a connecting plate; the beneficial effects of the above-mentioned prior art are: improving the flexibility of the detection device, the detection steps are simple and quick, and it is conducive to improving the detection efficiency.

[0004] However, the above mobile urban road bridge detection device still has some shortcomings in actual use:

[0005] 1. With the above-mentioned mobile urban road bridge detection device, the user can hold the pull rods on the front and back of the support plate through the sliding rods, and slide the two detection mechanisms left and right along the sliding grooves, which is convenient for the user to move left and right during the use of the detection mechanisms for detection. However, in non-destructive testing of bridges, it is necessary to detect bridge columns. When detecting bridge columns, it is necessary to detect different heights of the bridge columns, so that the device does not need to move significantly during detection, which is convenient for the operator to detect.

[0006] 2. The above-mentioned mobile urban road bridge detection device is attached to the top of the bridge or road through the springs under the bottom plate. When the bridge or road has unevenness, the bottom plate on the lower side will tilt downward, causing the springs on the tilted side of the bottom plate to shorten. However, when detecting, there will be vehicles driving on the road and the bridge, and the movement of the vehicles will cause the road and the bridge to vibrate, thus affecting the accuracy of the detection.

[0053] Reference Fig. 9 As shown, that is, the flip mechanism 4 in the present application; specifically, the flip mechanism 4 also includes a flip ring 43, a rotating ring 44, an active rod 45, a flip rod 46, a spring three 47, a clamping block two 48, a spring four 480 and a clamping groove two 481, the flip ring 43 is rotatably sleeved on the adjusting rod 363, the bottom of the flip ring 43 is sleeved with a rotating ring 44, and a plurality of active rods 45 cooperating with the driven rod 42 are evenly arranged along the circumference of the rotating ring 44. When the adjusting rod 363 rotates, the flip ring 43 can be driven to rotate together, when the flip ring 43 rotates, the rotating ring 44 can be driven to rotate together, when the rotating ring 44 rotates, the active rod 45 can be driven to rotate together, and when the active rod 45 rotates, the driven rod 42 can be driven to rotate together; the adjusting rod 36 3 is provided with a flip rod 46 which can slide under the restriction of the adjusting rod 363; a spring 3 47 is provided between the adjusting rod 363 and the flip rod 46, and the spring 3 47 can always provide an upward thrust for the flip rod 46; a clamping block 2 48 is provided on the front side of the flip rod 46, and the clamping block 2 48 and the flip rod 46 are connected by a plurality of springs 480; a clamping groove 2 481 which cooperates with the clamping block 2 48 is provided on the adjusting rod 363 and the flip ring 43; when the flip rod 46 moves, the spring 480 can be driven to move together; when the spring 480 moves, the clamping block 2 48 can be driven to move together; through the cooperation of the clamping block 2 48 and the clamping groove 2 481, when the adjusting rod 363 rotates, the flip ring 43 can be driven to rotate together.

[0054] During the specific implementation process, the operator presses the flip rod 46 to make the flip rod 46 move downward under the restriction of the adjusting rod 363. When the flip rod 46 moves, it can drive the spring four 480 to move together. When the spring four 480 moves, it can drive the block two 48 to move together. When the block two 48 moves to the slot two 481, the block two 48 enters the slot two 481 under the action of the spring four 480. Through the cooperation of the block two 48 and the slot two 481, when the adjusting rod 363 rotates, the flip ring 43 can be driven to rotate together. When the flip ring 43 rotates, the rotating ring 44 can be driven to rotate together. When the rotating ring 44 rotates, the active rod 45 can be driven to rotate together. When the active rod 45 rotates, it can drive the driven rod 42 to rotate together.

[0055] During operation: In the first step, when the moving wheel 11 rotates, it can drive the connecting shaft 10 to move. When the connecting shaft 10 moves, it can drive the fixing rod 12 to move together. When the fixing rod 12 moves, it can drive the driving motor 13 to move together. At the same time, when the connecting shaft 10 moves, it can drive the mounting ring 1 to move together through the shock absorbing mechanism 2, so that the mounting ring 1 moves to the position to be detected.

[0056] Step 2: The operator then adjusts the orientation of the flaw detector 3743 according to the inspection location. When inspecting the road surface of a road or a bridge, the operator rotates the locking plate 3745 to drive the rotating shaft 3741 to rotate together. When the rotating shaft 3741 moves, it can drive the rotating plate 3742 to rotate together. When the rotating plate 3742 rotates, it can drive the flaw detector 3743 to rotate together, so that the flaw detector 3743 faces the vertical plane. Then the operator presses the flip lever 46 to make the flip lever 4 6 moves downward under the restriction of the adjusting rod 363, and when the flip rod 46 moves, it can drive the spring 480 to move together, and when the spring 480 moves, it can drive the clamping block 48 to move together. When the clamping block 48 moves to the clamping groove 481, the clamping block 48 enters the clamping groove 481 under the action of the spring 480, and through the cooperation of the clamping block 48 and the clamping groove 481, when the adjusting rod 363 rotates, it can drive the flip ring 43 to rotate together, and when the flip ring 43 rotates, it can drive the rotating ring 44 to rotate together. When the rotating ring 44 rotates, the active rod 45 can be driven to rotate together, when the active rod 45 rotates, the driven rod 42 can be driven to rotate together, when the driven rod 42 rotates, the flip plate 40 can be driven to rotate together, when the flip plate 40 rotates, the synchronous rod 41 can be driven to rotate together, when the synchronous rod 41 rotates, the strip plate 32 can be driven to rotate together, when the strip plate 32 rotates, the square plate 370, the support plate 372 and the flaw detector 3743 can be driven to move together, so that the flaw detector 3743 is located below the mounting plate, so that the road surface of the road and the bridge can be inspected; when inspecting the bridge column of the bridge, the operator rotates the locking plate 3745 to make the flaw detector 3743 face the horizontal plane; then by pressing the flip rod 46, the operator rotates the adjusting rod 363 to drive the flaw detector 3743 to rotate, so that the flaw detector 3743 is located above the mounting ring 1, so that the flaw detector 3743 can not only detect the road surface of the road and the bridge, but also detect the bridge column of the bridge, thereby improving the practicality of the device.

[0057] Step 3: After adjusting the orientation of the flaw detector 3743, start the drive motor 13. When the output shaft of the drive motor 13 rotates, it can drive the transmission shaft 30 to rotate together. When the transmission shaft 30 rotates, it can drive the rotating circular plate 300 to rotate together. When the rotating circular plate 300 rotates, it can drive the rotating block 301 to rotate together. When the rotating block 301 rotates, it can drive the reciprocating screw 31 to rotate together. When the reciprocating screw 31 rotates, it can drive the connecting block 302 and the strip plate 32 to rotate together, so as to adjust the position of the strip plate 32, thereby adjusting the position of the flaw detector 3743 in the mounting plate.

[0058] Step 4: The operator then presses the adjusting rod 363 to move the adjusting rod 363 downward. When the adjusting rod 363 moves, it can drive the clamping block 1 365 to move together, so that the clamping block 1 365 moves into the clamping groove 1 366. Then the adjusting rod 363 is rotated. When the adjusting rod 363 rotates, it can drive the limiting ring 361 to rotate together. When the limiting ring 361 rotates, it can drive the bevel gear 2 362 to rotate together. When the bevel gear 2 362 rotates, it can drive the bevel gear 1 360 to rotate together. When 360 rotates, it can drive the reciprocating screw 31 to rotate together. When the reciprocating screw 31 rotates, it can drive the annular sleeve 35 to move back and forth. When the annular sleeve 35 moves, it can drive the adjusting block 33 to move together. When the adjusting block 33 moves, it can drive the L-shaped plate 371 to move together. When the L-shaped plate 371 moves, it can drive the square plate 370 to move together. When the square plate 370 moves, it can drive the supporting plate 372 to move together. By adjusting the position of the supporting plate 372, the position of the flaw detector 3743 can be further adjusted.

[0059] Step 5: When the square plate 370 moves, the horizontal plate 375 can be driven to move together. When the horizontal plate 375 moves, the rotating shaft 376 can be driven to move together. During the movement of the rotating shaft 376, the rotating shaft 376 can contact the arc-shaped spring piece 378. During this process, the triangular block 3780 on the arc-shaped spring piece 378 enters the triangular groove 3781, thereby driving the rotating shaft 376 to rotate. When the rotating shaft 376 rotates, it can drive the spur gear 377 to rotate together. When the spur gear 377 rotates, it can drive the rack 3770 to move up and down. When the rack 3770 moves, it can drive the support plate 372 to move together, thereby adjusting the height of the flaw detector 3743 to achieve

[0060] By adjusting the height of the flaw detector 3743, the bridge columns can be inspected during nondestructive testing, and different heights can be inspected when inspecting the bridge columns, thereby improving the practicability of the device and achieving precise movement of the flaw detector 3743 within a certain range, thereby being able to perform multi-point inspections on roads or bridge pavements within a certain range, making it convenient for operators to perform inspections without the need for operators to frequently move the flaw detector 3743.

[0061] Step 6: During the detection process, the vibration generated by the vehicles running on the roads and bridges is reduced by the spring 23, and the shock when the spring 23 rebounds after shock absorption and the impact from the road surface are suppressed by the telescopic rod 22, so as to reduce the impact of the vibration generated by the vehicles running on the roads and bridges on the detection, thereby improving the accuracy of the detection.
