Description

Technical Field

[0002] Pavement subsidence is the result of the combined effects of the earth's structure and human engineering activities, and poses a huge threat to the safety of surface and underground structures. With the acceleration of urbanization and the continuous increase in traffic volume, the problem of pavement subsidence has become increasingly prominent, posing a serious threat to the safety and service life of roads. Accurate and timely monitoring and early warning of pavement subsidence are of great significance.

DETAILED DESCRIPTION

[0068] See also Figures 1 to 8 In an embodiment of the present invention, a device for detecting regional road surface settlement in sections includes:

[0069] The positioning support frame 1 is a telescopic structure, with two sets symmetrically distributed and fixed on both sides of the road;

[0070] The longitudinal moving mechanism 2 is symmetrically arranged in two groups and is fixed on the top of each group of positioning support frames 1;

[0071] The transverse moving mechanism 3 is arranged perpendicularly to the longitudinal moving mechanism 2, and both ends of the transverse moving mechanism 3 are respectively fixed on each group of positioning support frames 1;

[0072] A horizontal limit assembly 4 is fixed to the bottom of the lateral moving mechanism 3;

[0073] A pressing mechanism 5 is fixed at the center of the lateral moving mechanism 3;

[0074] A detection device 6 is rotatably arranged at the bottom of the pressing mechanism 5;

[0075] The adjusting device 7 is fixedly arranged on the detecting device 6 .

[0076] In this embodiment, the longitudinal movement mechanism 2 includes:

[0077] Two slide rails 21 are symmetrically arranged and fixed on the top of the positioning support frame 1 on both sides respectively;

[0078] The moving block 22 is arranged corresponding to the slide rail 21, and is slidably arranged on the slide rail 21, and the top two ends of the moving block 22 are slidably connected to the horizontal moving mechanism 3;

[0079] The driving gear 23 is used to rotate the top of the moving block 22 and is connected to the bottom of the horizontal moving mechanism 3;

[0080] The control motor 24 is fixed to one end of the slide rail 21 and connected to the moving block 22 by rotating a screw rod.

[0081] That is to say, under the action of the positioning support frame 1, the longitudinal moving mechanisms 2 on both sides are on the same horizontal plane, and the transverse moving mechanism 3 remains horizontal. Driven by the control motor 24, the moving block 22 is driven to slide on the slide rail 21 by rotating the screw, thereby driving the transverse moving mechanism 3 to move on the slide rail 21, so that the transverse moving mechanism 3 drives the detection device 6 to move longitudinally, and the transverse moving mechanism 3 can be driven by the driving gear 23 to move transversely on the moving block 22, thereby driving the detection device 6 to move transversely, and the position of the detection device 6 on the road surface to be detected is adjusted, and different positions are selected to conduct comprehensive detection of the road surface in the area.

[0082] In this embodiment, the lateral movement mechanism 3 includes:

[0083] A movable plate 31 is slidably disposed on the movable blocks 22 at both sides, and the bottom of the movable plate 31 is meshed with the driving gear 23;

[0084] Two limit plates 32 are symmetrically arranged in front and back, fixed on the moving block 22, and the moving flat plate 31 is slidably arranged between the limit plates 32;

[0085] The positioning block 33 is fixed between the limiting plates 32 , is slidably connected to the moving plate 31 , and is located on the top of the moving plate 31 .

[0086] That is to say, driven by the driving gear 23 and restricted by the limit plate 32 and the positioning block 33, the movable plate 31 slides on the movable block 22, thereby driving the detection device 6 to move laterally, adjusting the position between the detection device 6 and the road surface, and detecting different positions of the road surface in the area, so as to make the detection results more accurate and comprehensive.

[0087] In this embodiment, the horizontal limit assembly 4 includes:

[0088] Two telescopic reset shafts 41 are symmetrically arranged, and the telescopic reset shafts 41 are provided with a fixed end and an extended end, the two are connected by a reset spring, and the fixed end is fixed to the bottom of the moving plate 31;

[0089] The horizontal plate 42 has two ends at the top thereof fixedly connected to the extended ends of the telescopic reset shaft 41;

[0090] A through hole 421 is provided at the center of the horizontal plate 42, and the through hole 421 corresponds to the bottom center of the detection device 6;

[0091] The pressing mechanism 5 comprises:

[0092] A hydraulic cylinder 51 is fixed at the top center of the moving plate 31;

[0093] The pressing shaft 52 is slidably disposed in the hydraulic cylinder 51 , and the pressing shaft 52 passes through the moving plate 31 and is rotatably connected to the detection device 6 .

[0094] That is to say, under the action of the horizontal plate 42, the detection device 6 is limited so that the detection device 6 is perpendicular to the road surface, and when the road surface is detected, the detection device 6 is not affected by the outside world and always remains perpendicular to the road surface, effectively avoiding errors caused by the center angle offset of the detection device 6, affecting the detection accuracy. When the hydraulic cylinder 51 drives the lower pressure shaft 52 to move downward, the detection device 6 moves downward under the push of the lower pressure shaft 52, and at the same time, the bottom of the detection device 6 passes through the through hole 421 of the horizontal plate 42, and then, under the continuous push of the lower pressure shaft 52, the horizontal plate 42 moves downward, and at the same time drives the telescopic reset shaft 41 to extend. After the detection device 6 contacts the road surface for settlement detection, the lower pressure shaft 52 is retracted under the drive of the hydraulic cylinder 51, and then drives the detection device 6 to move up and reset. At the same time, under the action of the reset spring inside the telescopic reset shaft 41, the horizontal plate 42 moves up and resets, completing the detection of the road surface in the given area.

[0095] In this embodiment, the detection device 6 includes:

[0096] The center stopper assembly 61 has its bottom connected to the through hole 421 on the horizontal plate 42;

[0097] The connecting shaft 62 has a bottom fixedly connected to the top of the central stop assembly 61 and a top rotatably connected to the lower pressing shaft 52;

[0098] A plurality of displacement components 63 are provided in an annular distribution and fixed on the outer side of the central limiting component 61;

[0099] A plurality of detection components 64 are provided in an annular distribution and are arranged corresponding to the displacement components 63 , and the detection components 64 are rotatably connected to the displacement components 63 .

[0100] That is to say, under the action of the center limit component 61, the detection device 6 is driven by the downward pressure mechanism 5 and moves synchronously with the horizontal limit component 4. The balance of the detection device 6 is maintained by the horizontal limit component 4, and the detection device 6 is driven by the downward pressure mechanism 5 to detect the road surface. When the downward pressure mechanism 5 drives the detection device 6 to move downward, the detection component 64 contacts the road surface. If there is settlement of the road surface in the detection area, the detection component 64 that contacts the road surface first will lift the displacement component 63 under the continuous push of the downward pressure mechanism 5. After all the detection components 64 are in contact with the road surface, the displacement component 63 is analyzed to determine the settlement of the road surface at different positions in the area.

[0101] In this embodiment, the center limiting assembly 61 includes:

[0102] The central column 611 is arranged corresponding to the through hole 421 on the horizontal plate 42, and the top is fixedly connected to the connecting shaft 62;

[0103] The limiting clamp ring 612 is fixed to the lower part of the central column 611 and is located above the through hole 421;

[0104] A limiting cone 613 is fixed at the bottom of the central column 611, and the limiting cone 613 passes through the through hole 421;

[0105] The limiting annular surface 614 is fixed on the central column 611 and is located above the limiting clamping ring 612;

[0106] The fixed top surface 615 is fixed on the upper end of the central column 611 .

[0107] That is to say, under the action of the limiting clamp 612 and the limiting cone 613, the center limiting component 61 is connected to the through hole 421, and under the mutual fit of the limiting clamp 612 and the horizontal plate 42, the balance of the detection device 6 is effectively maintained, which helps to improve the accuracy of the detection.

[0108] In this embodiment, the displacement component 63 includes:

[0109] A plurality of fixed shaft bodies 631 are provided in an annular distribution, the top of which is fixedly connected to the fixed top surface 615, and the bottom of which is fixedly connected to the limiting clamp ring 612;

[0110] The movable arc surface 632 is provided corresponding to the fixed shaft body 631 and is located above the limiting ring surface 614, and a plurality of the movable arc surfaces 632 form a complete circular ring;

[0111] The compression spring 633 is disposed on the fixed shaft 631 and is located between the movable arc surface 632 and the fixed top surface 615;

[0112] The connecting table 634 is fixed on the top of the movable arc surface 632 . The top of the connecting table 634 is fixedly connected to the adjusting device 7 , and a rotating motor is disposed inside one of the connecting tables 634 .

[0113] That is to say, when the pressing mechanism 5 drives the detection device 6 to move downward, the detection component 64 contacts the road surface. If there is settlement of the road surface in the detection area, the detection component 64 that contacts the road surface first, under the continuous push of the pressing mechanism 5, drives the corresponding movable arc surface 632 to move on the fixed shaft 631 through the connecting table 634, and compresses the compression spring 633. After all the detection components 64 are in contact with the road surface, the moving distance of the movable arc surface 632 on the fixed shaft 631 is analyzed to determine the settlement of the road surface at different positions in the area. After the detection is completed, the pressing mechanism 5 drives the detection device 6 to move upward and reset, and then under the action of the compression spring 633, the movable arc surface 632 moves and resets on the fixed shaft 631, and multiple movable arc surfaces 632 are restored to the same horizontal plane.

[0114] In this embodiment, the detection component 64 includes:

[0115] A plurality of rotating connecting rods 641 are provided in an annular distribution and are rotatably connected to the connecting table 634;

[0116] A contact roller 642 is rotatably disposed at an end of the rotating link 641 away from the connecting table 634;

[0117] The slideway 643 is disposed on a side of the rotating connecting rod 641 away from the center of the displacement assembly 63 .

[0118] That is to say, when the rotating link 641 rotates toward the center of the detection device 6, it drives the contact roller 642 to move toward the center of the detection device 6, and the ring formed by the detection points of the multiple detection components 64 becomes smaller; when the rotating link 641 rotates away from the center of the detection device 6, it drives the contact roller 642 to move away from the center of the detection device 6, and the ring formed by the detection points of the multiple detection components 64 becomes larger. With the rotation adjustment of the rotating link 641, the bottom center of the detection device 6 is used as the detection center, and the outer ring of the detection center is detected in real time in sequence, accurately reflecting the actual situation of road surface settlement, and under the rotation action of the connecting shaft 62, the detection device 6 can be driven to rotate as a whole to detect different points on the annular area where the detection component 64 is detected. Of course, it is necessary to pay attention to the position between the rotating link 641 and the horizontal plate 42. The rotation range of the rotating link 641 is limited by the horizontal plate 42.

[0119] In this embodiment, the adjusting device 7 comprises:

[0120] A plurality of adjusting rails 71 are provided in an annular arrangement and fixed on the top of the connecting table 634;

[0121] A plurality of adjusting arc surfaces 72 are provided corresponding to the adjusting track 71 and are rotatably connected to the adjusting track 71. The plurality of adjusting arc surfaces 72 form a complete ring, and an arc track 73 is provided on the adjusting arc surface 72;

[0122] The transmission gear 74 is meshed with the inner ring of the adjustment arc surface 72 and is fixedly connected to the rotating motor inside the connection table 634;

[0123] The moving member 75 is slidably disposed in the corresponding adjustment track 71 and the arc track 73;

[0124] The moving rod assembly 76 has one end fixedly connected to the bottom of the moving member 75 and one end slidably connected to the slideway 643 .

[0125] That is to say, driven by the rotating motor, the transmission gear 74 rotates, and when the transmission gear 74 drives the adjusting arc surface 72 to rotate counterclockwise, under the restriction of the arc path 73, the moving part 75 moves toward the center of the detection device 6, and then under the restriction of the moving rod assembly 76, the rotating connecting rod 641 rotates toward the center of the detection device 6; when the transmission gear 74 drives the adjusting arc surface 72 to rotate clockwise, under the restriction of the arc path 73, the moving part 75 moves away from the center of the detection device 6, and then under the restriction of the moving rod assembly 76, the rotating connecting rod 641 rotates away from the center of the detection device 6, and under the adjustment action of the adjustment device 7, the position of the contact roller 642 of the detection assembly 64 corresponding to the road surface is adjusted and changed, so as to realize the detection of different outer rings of the same center in sequence.

[0126] In this embodiment, the moving rod assembly 76 includes:

[0127] A fixed roller 761, fixed to the bottom of the moving member 75;

[0128] A rolling wheel 762, which is arranged to roll in the slideway 643;

[0129] The adjusting connecting rods 763 are symmetrically provided with two ends, and the two ends are respectively fixedly connected to the two sides of the fixed roller 761 and rotatably connected to the two sides of the rolling roller 762.

[0130] That is to say, when the transmission gear 74 drives the adjustment arc surface 72 to rotate counterclockwise, under the limitation of the arc track 73, the movable member 75 moves toward the center of the detection device 6, and at the same time drives the adjustment link 763 to move toward the center of the detection device 6 through the fixed roller 761, and then the rolling roller 762 moves in the slideway 643 toward the position where the connecting table 634 is located, pushing the rotating link 641 to rotate toward the center of the detection device 6; when the transmission gear 74 drives the adjustment arc surface 72 to rotate clockwise, under the limitation of the arc track 73, the movable member 75 moves away from the center of the detection device 6, and at the same time drives the adjustment link 763 to move away from the center of the detection device 6 through the fixed roller 761, and then the rolling roller 762 moves in the slideway 643 toward the position where the contact roller 642 is located, pulling the rotating link 641 to rotate away from the center of the detection device 6, and then under the adjustment action of the adjustment device 7, the position of the contact roller 642 of the detection component 64 corresponding to the road surface is adjusted and changed, thereby realizing fixed-point multi-position detection.

[0131] During the specific implementation, first, under the action of the positioning support frame 1, the longitudinal moving mechanisms 2 on both sides are placed on the same horizontal plane, and the lateral moving mechanism 3 is kept horizontal. Under the joint action of the longitudinal moving mechanism 2 and the lateral moving mechanism 3, the position of the detection device 6 on the road surface to be detected is adjusted. After the detection position is determined, the transmission gear 74 is driven to rotate by the rotating motor in the connecting table 634 in the displacement component 63. When the transmission gear 74 drives the adjustment arc surface 72 to rotate counterclockwise, under the restriction of the arc 73, the moving member 75 moves toward the center of the detection device 6, and then under the restriction of the moving rod component 76, the connecting rod is rotated. 641 rotates toward the center of the detection device 6, driving the contact roller 642 to move toward the center of the detection device 6; when the transmission gear 74 drives the adjustment arc surface 72 to rotate clockwise, under the restriction of the arc path 73, the moving member 75 moves away from the center of the detection device 6, and then under the restriction of the moving rod assembly 76, the rotating connecting rod 641 rotates away from the center of the detection device 6, driving the contact roller 642 to move away from the center of the detection device 6, so as to realize the detection of different outer rings of the same center in sequence, and under the rotation of the connecting shaft 62, the detection device 6 can be driven to rotate as a whole, and the annular area of ​​the detection assembly 64 can be detected. The detection device 6 moves downward under the push of the lower pressure shaft 52, and the bottom of the detection device 6 passes through the through hole 421 of the horizontal plate 42. Then, under the continuous push of the lower pressure shaft 52, the horizontal plate 42 moves downward, and the telescopic reset shaft 41 is extended. As the detection device 6 contacts the road surface, settlement detection is performed. If there is settlement on the road surface in the detection area, the detection component 64 that contacts the road surface first drives the corresponding moving arc surface 632 to move on the fixed shaft 631 through the connecting table 634 under the continuous push of the lower pressure mechanism 5, so as to compress the road surface. The spring 633 is compressed, and after all the detection components 64 are in contact with the road surface, the moving distance of the movable arc surface 632 on the fixed shaft 631 is analyzed, and the road surface settlement at different positions in the area can be determined. After the detection is completed, the pressing mechanism 5 drives the detection device 6 to move up and reset, and then under the action of the compression spring 633, the movable arc surface 632 moves and resets on the fixed shaft 631, and multiple movable arc surfaces 632 return to the position on the same horizontal plane. The relative position of the contact roller 642 and the road surface can be adjusted again through the adjustment device 7 and the connecting shaft 62, and then the road surface in this area can be detected.

[0132] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
