Description

Technical Field

[0001] The invention relates to a roadbed settlement detection device and method, belonging to the technical field of measurement. Background Art

[0002] The roadbed is a geotechnical structure formed by excavation or filling. The main function of the roadbed is to provide necessary conditions for road paving. The roadbed is prone to settlement and deformation due to factors such as soil holes. After the road is paved, the roadbed settlement is likely to cause cracking, skewing and other phenomena, causing certain hidden dangers to vehicle driving. Therefore, when the roadbed is completed, the roadbed settlement detection device is generally used to detect the settlement of the roadbed.

[0003] At present, the roadbed settlement detection device generally consists of a mobile vehicle and a laser ranging sensor and other ranging electronic components installed on the mobile vehicle. When in use, the mobile vehicle is first moved on the roadbed, and the ranging electronic components collect roadbed surface data at the same time. When the roadbed surface is deformed, the collected roadbed surface data will change, thereby providing information for judging whether the roadbed has settled and the location of the roadbed settlement;

[0018] A method for processing a roadbed settlement detection device comprises the following steps:

[0019] The first step is pretreatment, firstly, two connecting plates, two mounting plates and other components are moved downward by threaded rods and functional cylinders, so that the guide plate, multiple hard brushes, the first moving wheel and the second moving wheel are in contact with the roadbed surface, and then the mounting ring is connected to the driving vehicle by a latch, and then the frame guide frame and multiple rectangular rods are moved downward by screw rods and adjustment cylinders, and multiple top plates are unfolded with the assistance of multiple first folding frames and multiple second folding frames, and the length of the structure formed by the multiple top plates is adjusted;

[0020] The second step is moving, by driving the vehicle to move the mounting ring and the connecting rod, and the vibration generated by the driving vehicle will be eliminated under the action of multiple ropes, multiple first rolling members, multiple second rolling members and multiple elastic members, and the T-shaped plate, two mounting plates, two connecting plates, multiple top plates and other components are moved, and at the same time, two driving devices, two transmission rollers and two auxiliary rollers are used to make the two conveyor belts move relative to each other, and then make the multiple L-shaped frames move in a circular motion, and make the multiple hard brushes move along the roadbed surface, and make the two guide plates also move along the roadbed surface, so as to transport impurities such as pebbles on the roadbed surface to both sides of the roadbed;

[0021] The third step is detection. The movement of multiple top plates will cause multiple straight cylinders and multiple load-bearing columns to move, and multiple detection wheels to move along the roadbed surface. When the detection wheel moves to a local area on the roadbed surface that has been deformed downward due to settlement, the detection wheel moves downward into the deformation position under the action of the corresponding load-bearing column. At this time, the distance between the detector and the load-bearing column changes, and the distance data detected by the detector changes, thereby determining whether the roadbed has settled and the settlement position of the roadbed.

[0022] Beneficial effects of the present invention:

[0023] 1. When the detection wheel moves to a position where a certain area on the roadbed surface is deformed downward due to settlement, the corresponding detection wheel is brought into contact with the deformed roadbed surface again through the corresponding load-bearing column, the corresponding guide plate and the corresponding straight cylinder. With the assistance of the remaining load-bearing columns, the guide plate, the annular limit plate and the straight cylinder, the distance between the assembly formed by the multiple top plates and the roadbed surface remains unchanged, and the corresponding detector is used to detect the change in the distance data between the corresponding detector and the corresponding load-bearing column, thereby providing information for determining whether the roadbed has settled and the position of the roadbed settlement, which is used to complete the detection of roadbed settlement and realize the setting of the detection environment in a sealed space formed by the straight cylinder, the top plate and the guide plate, effectively reducing the probability of obstruction such as scattering of the detection operation due to impurities such as dust floating from the outside, and effectively ensuring the accuracy of the detection effect.

[0024] 2. Through the threaded rod and the functional cylinder, the two connecting plates, two mounting plates, the T-shaped plate, the round box and the round rod are moved downward to the appropriate position, and the multiple first moving wheels and the second moving wheels are all in contact with the roadbed surface, so that the structure formed by multiple straight cylinders, multiple load-bearing columns and multiple detection wheels can be placed auxiliary, effectively reducing the probability of the structure tilting, etc., with high stability, effectively ensuring the accuracy of the detection effect.

[0025] 3. By adjusting the cylinder, the screw, the frame guide frame and the multiple rectangular rods, downward pressure is applied to the tops of the multiple first folding frames and the tops of the multiple second folding frames, so that the structure formed by the multiple top plates can be unfolded to a suitable length, and the length of the assembly formed by the multiple top plates can be adjusted, which effectively meets the settlement detection of roadbeds of different widths, improves the scope of use, and has good practicality.

[0026] 4. The vibration generated by the running vehicle is initially offset by multiple ropes, and the vibration is offset again by multiple first universal balls, multiple second universal balls, round boxes, discs and multiple elastic parts, so as to achieve multiple offsets of the vibration generated by the driving vehicle, and effectively reduce the probability of vibration-induced jumping of the mechanism formed by multiple top plates, multiple straight cylinders, multiple load-bearing columns and multiple detection wheels, etc., with high stability, effectively ensuring the accuracy of the detection effect.

[0027] 5. Through two motors, two transmission rollers, two auxiliary rollers, two conveyor belts, multiple L-shaped frames and multiple hard brushes, pebbles and other impurities on the roadbed surface are transported to the opposite sides of the roadbed surface, and two guide plates are used to discharge the impurities to the outside of the roadbed surface, so as to clean up the impurities on the surface to be detected on the roadbed, effectively reducing the probability of the mechanism formed by multiple top plates, multiple straight cylinders, multiple load-bearing columns and multiple detection wheels moving upward as a whole due to pebbles and other impurities, and effectively ensuring the accuracy of the detection effect.

[0028] 6. The dust and other impurities that are raised are extracted and collected through the exhaust fan, two hoses, two outer shells, two extraction cylinders, two main pipes, two hollow shafts, two inner cylinders, two connecting cylinders and two filter bags, so that the dust and other impurities raised by cleaning small stones and other impurities can be collected in time, effectively reducing the probability of the raised dust and other impurities falling on the roadbed surface between the two mounting plates, and further effectively reducing the probability of the overall upward movement of the mechanism formed by multiple top plates, multiple straight cylinders, multiple load-bearing columns and multiple detection wheels, effectively ensuring the accuracy of the detection effect.

[0056] Then, the driving vehicle is started and made to travel on the roadbed surface, thereby pulling the connecting rod 85 to move, and the mounting plate 83 to move, and with the assistance of multiple ropes 82, round boxes 81, multiple second universal balls 892, functional plates 89, round rods 87 and other components, multiple top plates 1 are made to move synchronously, thereby making multiple straight cylinders 2 and other components move, and then making multiple detection wheels 4 move along the roadbed surface;

[0057] At this time, the vibration generated by the operation of the driving vehicle will be transmitted to the mounting plate 83 through the mounting ring 84 and the connecting rod 85, and the multiple ropes 82 will initially offset the vibration, and the ropes 82 in a straight state will still transmit the remaining vibration to the round box 81, and with the assistance of the multiple first universal balls 891 and the multiple second universal balls 892, the round box 81 and the disc will move relative to each other, thereby compressing or stretching the multiple elastic members 893, so that the multiple elastic members 893 all generate elastic force, and the elastic force of the multiple elastic members 893 will offset the vibration again, thereby achieving multiple offsets of the vibration generated by the driving vehicle, effectively reducing the probability of the mechanism formed by the multiple top plates 1, the multiple straight cylinders 2, the multiple load-bearing columns 3 and the multiple detection wheels 4 and other components jumping due to vibration, with high stability, effectively ensuring the accuracy of the detection effect;

[0058] In the process that multiple detection wheels 4 are moving along the roadbed surface, when the detection wheel 4 moves to a position where a certain area on the roadbed surface is deformed downward due to settlement, a distance is generated between the corresponding detection wheel 4 and the deformed roadbed surface, while the remaining detection wheels 4 are still in contact with the normal roadbed surface, so that with the assistance of the remaining load-bearing columns 3, guide plates 31, annular limit plates 21 and straight cylinders 2, the distance between the assembly and the roadbed surface remains unchanged, and at the same time, under the action of the corresponding load-bearing columns 3 themselves, the corresponding load-bearing columns 3 and the corresponding guide plates 31 move downward along the corresponding straight cylinders 2, so that the corresponding detection wheels 4 are in contact with the roadbed surface again;

[0059] At this time, the distance between the corresponding detector and the corresponding load-bearing column 3 changes, and the distance data detected by the corresponding detector changes, thereby providing information for judging whether the roadbed has settled and the position of the roadbed settlement, which is used to complete the detection of roadbed settlement and realize setting the detection environment in a sealed space formed by the straight tube 2, the top plate 1 and the guide plate 31, effectively reducing the probability of obstructions such as scattering of the detection operation due to impurities such as dust floating in the outside world, and effectively ensuring the accuracy of the detection effect.

[0060] Embodiment 2: Multiple top plates 1, multiple straight cylinders 2, multiple load-bearing columns 3, multiple detection wheels 4, multiple laser ranging sensors 18, multiple annular limit plates 21 and multiple guide plates 31 are used to detect roadbed settlement. However, the roadbed surface is prone to impurities such as pebbles. When the moving detection wheel 4 comes into contact with the impurities, the corresponding detection wheel 4, load-bearing column 3, guide plate 31, annular limit plate 21 and straight cylinder 2 move upward, causing the mechanism formed by multiple top plates 1, multiple straight cylinders 2, multiple load-bearing columns 3 and multiple detection wheels 4 to move upward as a whole. There is a high probability that the remaining load-bearing columns 3 and guide plates 31 move downward, causing the corresponding laser ranging sensor 18 to detect changes in distance data, which will affect the accuracy of the detection effect.

[0061] In order to solve the above problems, Figure 1 , Figure 5 and Figure 6 As shown, two conveyor belts 71 arranged along the length direction of the mounting plate 7 are respectively arranged on the lower sides of the two mounting plates 7, and the conveyor belts 71 are used to provide a mounting carrier for the L-shaped frame 72, and two driving rollers 61 respectively meshed on the inner left walls of the two conveyor belts 71 are respectively rotatably connected to the lower end of the left portion of the mounting plate 7, and the conveyor belt 71 is moved through the driving rollers 61, and then two auxiliary rollers 79 respectively meshed on the inner right walls of the two conveyor belts 71 are respectively rotatably connected to the lower end of the right portion of the mounting plate 7, and the movement of the conveyor belt 71 is assisted by the auxiliary rollers 79, and the driving rollers 61 are used in conjunction with the auxiliary wheels to flexibly connect the conveyor belt 71 and the mounting plate 7;

[0062] The fixed parts of the driving device connecting the two output shafts with the driving roller 61 are respectively installed on the upper right ends of the two connecting plates 5. The driving roller 61 is driven to rotate through the driving device. The driving device can adopt a motor 6, and a plurality of L-shaped frames 72 extending from the lower side of the conveyor belt 71 are equidistantly installed on the outer end of the conveyor belt 71. The L-shaped frames 72 are used to provide a mounting carrier for the hard brush 73. Then, the plurality of hard brushes 73 are respectively arranged on the lower ends of the transverse parts of the plurality of L-shaped frames 72. The hard brushes 73 are used to clean up impurities such as pebbles on the roadbed surface, and two guide plates 53 arranged in a V-structure with a width on the left and a narrowness on the right, which are located outside the detection wheel 4 and on the left side of the mounting plate 7, are respectively installed on the lower left ends of the two connecting plates 5.

[0063] When the multiple first moving wheels 76 and the second moving wheels 86 are moved along the roadbed surface by the driving vehicle, the two motors 6 are started to drive the two transmission rollers 61 to rotate relative to each other, and with the assistance of the two auxiliary rollers 79, the two conveyor belts 71 are rotated relative to each other, so that the multiple L-shaped frames 72 are moved in a circular motion, so that the multiple hard brushes 73 are moved along the roadbed surface and move in a circular motion at the same time, and the hard brushes 73 moving to the outside transport impurities such as pebbles on the roadbed surface to the opposite sides of the roadbed surface, thereby transporting the impurities to the opposite edge positions of the roadbed surface;

[0064] At this time, the two guide plates 53 are in contact with the impurities located on the edge positions of the opposite sides of the roadbed surface respectively, and the guide plates 53 are in operation, so that the impurities continue to be transported outward along the guide plates 53, and then the impurities are discharged from the outside of the roadbed surface, thereby cleaning the impurities on the surface to be detected on the roadbed, effectively reducing the probability of the mechanism formed by multiple top plates 1, multiple straight cylinders 2, multiple load-bearing columns 3 and multiple detection wheels 4 moving upward as a whole due to impurities such as pebbles, and effectively ensuring the accuracy of the detection effect.

[0065] Embodiment 3: Two motors 6, two drive rollers 61, two auxiliary rollers 79, two conveyor belts 71, multiple L-shaped frames 72, multiple hard brushes 73 and two guide plates 53 are used to discharge impurities such as pebbles on the roadbed surface to be detected to the outside of the roadbed surface. However, some impurities such as tiny volumes and dust are easily lifted up during the cleaning process using the hard brushes 73, resulting in a high probability that the lifted tiny volumes, dust and other impurities will float between the two mounting plates 7 and fall down. As a result, the fallen tiny volumes, dust and other impurities will cause the mechanism formed by multiple top plates 1, multiple straight cylinders 2, multiple load-bearing columns 3 and multiple detection wheels 4 to move upward as a whole, which will affect the accuracy of the detection effect.

[0066] In order to solve the above problems, Figure 9-12As shown, the function plate 74 is rotatably connected to the mounting plate 7 through the hollow shaft 703, and two main pipes 702 located in the conveyor belt 71 and between the driving roller 61 and the auxiliary roller 79, which are respectively connected to the lower ends of the two hollow shafts 703, are respectively installed on the lower ends of the two mounting plates 7. Through the main pipe 702, a mounting carrier is provided for a plurality of L-shaped suction pipes 701, and the vertical parts of the plurality of L-shaped suction pipes 701 with suction ports facing the roadbed surface are equidistantly connected and arranged on the lower end of the main pipe 702, and the L-shaped suction pipes 701 are used to extract the dust generated by cleaning;

[0067] The two extraction cylinders 784 connected to the upper ends of the two hollow shafts 703 are respectively installed on the upper ends of the two functional plates 74 facing outwards, and the extraction cylinders 784 are used to provide a mounting carrier for the inner cylinder 787 and other components, and the two outer cylinders 788 extending into the outer shell 783 are respectively arranged on the inner ends of the two extraction cylinders 784, and the outer cylinders 788 are used to facilitate the disassembly and assembly between the extraction cylinders 784 and the outer shell 783, and then the two inner cylinders 787 located in the outer cylinders 788 and extending into the connecting cylinder 786 are respectively connected and installed on the inner ends of the two extraction cylinders 784, and the inner cylinders 787 are used to facilitate the disassembly and assembly between the extraction cylinders 784 and the connecting cylinder 786;

[0068] The two outer shells 783 are respectively threadedly connected to the inner ends of the two outer cylinders 788, and a filtering space is provided through the outer shells 783. The two hoses 782 whose other ends are connected to the exhaust fan 781 are respectively connected and installed on the inner ends of the two outer shells 783. The exhaust fan 781 is connected and installed with the outer shells 783 through the hoses 782. The exhaust fan 781 is then set at the middle position of the upper end of the auxiliary frame 78. The exhaust fan 781 is used for extraction operations, and the two connecting cylinders 786 extending into the outer cylinder 788 are respectively threadedly connected to the inner ends of the two inner cylinders 787. The connecting cylinder 786 and the inner cylinder 787 are used together to connect the filter bag 785 with the extraction cylinder 784. Then the two filter bags 785 respectively located in the two outer shells 783 are respectively connected and installed on the inner ends of the two connecting cylinders 786. The extracted dust and other impurities are collected through the filter bags 785.

[0069] When the multiple first moving wheels 76 and the second moving wheels 86 are moved along the roadbed surface by the driving vehicle, the multiple hard brushes 73 are moved along the roadbed surface and perform a circular motion by using two motors 6, two driving rollers 61, two auxiliary rollers 79, two conveyor belts 71 and multiple L-shaped frames 72, and the hard brushes 73 moving to the outside convey impurities such as pebbles on the roadbed surface to the opposite sides of the roadbed surface, and at the same time, impurities such as dust on the roadbed surface are lifted up.

[0070] At the same time, the exhaust fan 781 is started, so that negative pressure is generated at the suction port position of the multiple L-shaped suction pipes 701. Under the action of the negative pressure, the raised dust and other impurities enter the L-shaped suction pipes 701, and enter the filter bag 785 along the main pipe 702, the hollow shaft 703, the extraction cylinder 784, the inner cylinder 787 and the connecting cylinder 786. The filter bag 785 collects the dust and other impurities, and timely collects the dust and other impurities raised by cleaning small stones and other impurities, effectively reducing the probability of the raised dust and other impurities falling on the roadbed surface between the two mounting plates 7, and further effectively reducing the probability of the mechanism formed by the multiple top plates 1, the multiple straight cylinders 2, the multiple load-bearing columns 3 and the multiple detection wheels 4 and other components moving upward as a whole, effectively ensuring the accuracy of the detection effect;

[0071] When the detection work is completed, the outer shell 783 is first rotated to disassemble the outer shell 783 and the outer cylinder 788, and then the connecting cylinder 786 is rotated to disassemble the connecting cylinder 786 and the inner cylinder 787, and then the filter bag 785 is disassembled to realize convenient cleaning of dust and other impurities collected in the filter bag 785, effectively ensuring the subsequent sedimentation detection operation.

[0072] A method for processing a roadbed settlement detection device comprises the following steps:

[0073] The first step is pre-processing. First, the two connecting plates 5, the two mounting plates 7 and other components are moved downward by the threaded rod 51 and the functional cylinder 52, so that the guide plate 53, the multiple hard brushes 73, the first moving wheel 76 and the second moving wheel 86 are in contact with the roadbed surface, and then the mounting ring 84 is connected to the driving vehicle by a latch. Then, the frame guide frame 11 and the multiple rectangular rods 12 are moved downward by the screw rod 15 and the adjustment cylinder 16, and the multiple top plates 1 are unfolded with the assistance of the multiple first folding frames 13 and the multiple second folding frames 14, and the length of the structure formed by the multiple top plates 1 is adjusted;

[0074] The second step is to move. The mounting ring 84 and the connecting rod 85 are moved by driving the vehicle. The vibration caused by driving the vehicle is eliminated by the multiple ropes 82, multiple first rolling members, multiple second rolling members and multiple elastic members 893. The T-shaped plate 8, two mounting plates 7, two connecting plates 5, multiple top plates 1 and other components are moved. At the same time, two driving devices, two transmission rollers 61 and two auxiliary rollers 79 are used to make the two conveyor belts 71 move relative to each other, thereby making the multiple L-shaped frames 72 move in a circular motion, and making the multiple hard brushes 73 move along the roadbed surface, and making the two guide plates 53 move along the roadbed surface, so as to transport impurities such as pebbles on the roadbed surface to both sides of the roadbed.

[0075] The third step is detection. The movement of multiple top plates 1 will cause multiple straight tubes 2 and multiple load-bearing columns 3 to move, and multiple detection wheels 4 to move along the roadbed surface. When the detection wheel 4 moves to a position where a local area on the roadbed surface is deformed downward due to settlement, the detection wheel 4 moves downward into the deformation position under the action of the corresponding load-bearing column 3. At this time, the distance between the detector and the load-bearing column 3 changes, and the distance data detected by the detector changes, thereby determining whether the roadbed has settled and the settlement position of the roadbed.

[0076] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
