Roadbed pavement flatness detection device

Abstract

According to the roadbed pavement flatness detection device provided by the invention, when the roadbed pavement flatness detection device moves on a flat pavement, the movable assembly is kept at the initial position due to the flat pavement, and laser passes through the light transmission hole from the emitter and is directly emitted to the receiver, so that the pavement is flat. When the roadbed pavement flatness detection device passes through an uneven pavement, the movable assembly moves relative to the main body according to the convex-concave change of the pavement, and the position of the light hole is changed, so that the laser is shielded and cannot be directly emitted to the receiver, and the pavement is uneven. Through the continuous laser detection of the roadbed pavement flatness detection device, the rapid and continuous detection of the large-area pavement flatness can be realized, and the detection efficiency is greatly improved.

[0002] The roadbed is the foundation of the road structure, responsible for distributing and transferring the load of the upper pavement structure and vehicles. The roadbed can effectively disperse the load and reduce the pressure on the foundation.

[0003] The flatness of the road surface directly affects the driving comfort. If the road surface is uneven, it will cause the vehicle to bump while driving, affecting driving safety. Severe unevenness may also cause the vehicle to lose control and increase the risk of traffic accidents.

[0004] Therefore, it is particularly important to detect the flatness of the roadbed and pavement. The existing detection method is the straight-line ruler detection method. The straight-line ruler detection method is simple to operate and does not require complex equipment or professional technical knowledge. Ordinary construction workers can perform measurements after simple training.

[0005] The accuracy of the linear ruler detection method is low, especially when detecting small unevenness in a large area, it cannot accurately reflect the actual situation. It is necessary to manually move the linear ruler and measure, which is labor-intensive and inefficient for large-area road detection work.

[0006] Therefore, there is an urgent need for a roadbed and pavement flatness detection device to solve the problem of low detection efficiency. Utility Model Content

[0047] The embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0048] It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a central component at the same time. When a component is considered to be "located on" another component, it may be directly located on the other component or there may be a central component at the same time. The terms "top", "bottom", "upper", "lower", "left", "right", "front", "back", and similar expressions used herein are for illustrative purposes only.

[0049] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0050] The embodiment of the present application provides a roadbed and pavement flatness detection device 100, comprising:

[0051] A main body 110, wherein a rolling wheel 111 is provided at the bottom of the main body 110, and the rolling wheel 111 is used for driving;

[0052] A first laser emitter 120 is disposed at one side of the main body 110 and emits laser along a first direction A;

[0053] A first laser receiver 130 is disposed at the other side of the main body 110 , and the first direction A is the direction from the first laser emitter 120 to the first laser receiver 130 ;

[0054] The movable component 140 is disposed at the bottom of the main body 110 and is telescopically connected to the main body 110. The movable component 140 is provided with a light-transmitting hole 140a along the first direction A;

[0055] Wherein, when the roadbed is uneven, the movable component 140 moves relative to the main body 110 to shield the laser emitted by the first laser emitter 120;

[0056] When the roadbed is leveled, the laser emitted by the first laser emitter 120 passes through the light-transmitting hole 140 a and irradiates the first laser receiver 130 .

[0057] Please refer to Figures 1 to 6 In this embodiment, when the roadbed and pavement flatness detection device 100 moves on a flat road surface, the movable component 140 remains in its original position due to the flat road surface, and the laser is emitted from the transmitter directly to the receiver through the light-transmitting hole 140a, indicating that the road surface is flat.

[0058] When the roadbed and pavement flatness detection device 100 passes over an uneven road surface, the movable component 140 moves relative to the main body 110 according to the convex and concave changes of the road surface, and the position of the light-transmitting hole 140a changes, causing the laser to be blocked and unable to directly emit to the receiver, indicating that the road surface is uneven.

[0059] Through the continuous laser detection of the roadbed and pavement flatness detection device 100, rapid and continuous detection of the flatness of a large area of ​​the road can be achieved, greatly improving the detection efficiency.

[0060] By utilizing the rectilinear propagation characteristics of laser light and combining the precise adjustment mechanism of the active component 140 , minute unevenness of the road surface can be identified and measured with high precision, thereby improving the accuracy of the detection results.

[0061] It should be noted that the rolling wheel 111 enables the roadbed and pavement flatness detection device 100 to be easily moved on the roadbed and pavement without manual handling, thereby achieving continuous road surface flatness detection. The rolling wheel 111 is a roller.

[0062] The first laser emitter 120 is installed on one side of the main body 110 and can emit laser along a first direction A; correspondingly, the first laser receiver 130 is installed on the other side of the main body 110 to receive laser from the first laser emitter 120 .

[0063] When the road surface is smooth, the laser is directly emitted from the first laser emitter 120 through the light-transmitting hole 140 a to the first laser receiver 130 ; when the road surface is uneven, the laser is blocked by the movable component 140 and does not reach the first laser receiver 130 .

[0064] The movable assembly 140 is located at the bottom of the main body 110 and is connected to the main body 110 in a telescopic manner. The movable assembly 140 is provided with a light-transmitting hole 140a along the first direction A. The light-transmitting hole 140a is a through hole, and the main body 110 is a trolley.

[0065] The movement of the movable component 140 can adjust the position of the light-transmitting hole 140 a according to the flatness of the road surface, thereby controlling whether the laser can reach the first laser receiver 130 .

[0066] In at least one embodiment of the present application, the active component 140 includes:

[0067] An elastic member 141, one end of which is disposed on the main body 110;

[0068] The movable wheel 142 , one end of the elastic member 141 away from the main body 110 abuts against the movable wheel 142 .

[0069] Please refer to Figures 1 to 6 In this embodiment, when the roadbed and pavement flatness detection device 100 passes through a flat area of ​​the road surface, the movable wheel 142 remains stable and the elastic member 141 does not deform, so that the light-transmitting hole 140a and the first laser emitter 120 and the first laser receiver 130 remain in the correct alignment position, allowing the laser to pass through the light-transmitting hole 140a smoothly.

[0070] When encountering a road depression, the movable wheel 142 sinks, and the elastic member 141 stretches, causing the movable assembly 140 to move downward, and the position of the light-transmitting hole 140a also moves downward relative to the laser emission path, causing the laser path to be changed, reflecting the information of the road depression.

[0071] When encountering a bump on the road surface, the movable wheel 142 rises, the elastic member 141 is compressed, the movable assembly 140 moves upward, and the position of the light-transmitting hole 140a changes to block the laser path, reflecting the information of the bump on the road surface.

[0072] The elastic member 141 and the movable wheel 142 can automatically adapt to the unevenness of different road surfaces, thereby achieving high-precision detection of the flatness of the road surface.

[0073] Compared with the traditional manual detection method, the roadbed and pavement flatness detection device 100 can quickly and continuously complete the road surface flatness detection, thereby improving the work efficiency and the continuity of the detection.

[0074] It should be noted that the elastic member 141 is a retractable component such as a spring, rubber, etc., one end of which is fixed to the main body 110 of the roadbed and pavement flatness detection device 100 , and the other end of which is in contact with the movable wheel 142 .

[0075] The main function of the elastic member 141 is to provide a flexible support for the movable wheel 142 that can automatically adjust its height according to different road conditions. When the movable wheel 142 moves due to hitting a bump or depression on the road surface, the elastic member 141 can extend or shorten accordingly, thereby allowing the movable assembly 140 to maintain contact with the road surface or adjust its position.

[0076] The movable wheel 142 is in direct contact with the road surface, and is connected to the main body 110 of the roadbed and road surface flatness detection device 100 through the elastic member 141. It can move up and down when encountering uneven road surface to adapt to the uneven changes of the road surface.

[0077] The function of the movable wheel 142 is to reflect the smoothness of the road surface in real time. Its movement directly affects the position of the movable assembly 140, especially the position of the light-transmitting hole 140a, thereby controlling whether the laser can be transmitted to the first laser receiver 130 through the light-transmitting hole 140a.

[0078] In at least one embodiment of the present application, the movable wheel 142 includes:

[0079] A connecting rod 1421, one end of which is telescopically connected to the main body 110, the connecting rod 1421 abuts against the elastic member 141, the light-transmitting hole 140a is formed on the connecting rod 1421 and penetrates the connecting rod 1421 along the first direction A;

[0080] The detection wheel 1422 is rotatably connected to an end of the connecting rod 1421 away from the elastic member 141 .

[0081] Please refer to Figures 1 to 6 In this embodiment, when the roadbed and pavement flatness detection device 100 moves along the road surface, the detection wheel 1422 directly contacts the road surface and moves up and down according to the flatness of the road surface.

[0082] If a protrusion or depression is encountered, the position change of the detection wheel 1422 causes the connecting rod 1421 to move relative to the main body 110. Since the connecting rod 1421 abuts against the elastic member 141, the elastic member 141 extends or contracts accordingly, thereby adjusting the position of the movable component 140, especially the position of the light transmission hole 140a.

[0083] If the position of the light-transmitting hole 140 a changes due to the uneven road surface, the laser light is blocked or allowed to pass through and detected by the first laser receiver 130 , thereby evaluating the flatness of the road surface.

[0084] The roadbed and pavement flatness detection device 100 can automatically adapt to different road conditions. No matter whether the road surface is convex or concave, the road surface condition can be accurately reflected by adjusting the position of the movable component 140, thereby increasing the applicable scope of the detection.

[0085] By finely adjusting the position of the movable component 140, the relative position between the light-transmitting hole 140a and the first laser emitter 120 and the first laser receiver 130, the road surface flatness can be detected very accurately, providing higher accuracy than traditional methods.

[0086] The connecting rod 1421 is roughly rod-shaped, and the detection wheel 1422 is roller-shaped.

[0087] In at least one embodiment of the present application, the main body 110 is provided with an activity hole 110a;

[0088] The connecting rod 1421 passes through the movable hole 110 a and is telescopically connected to the main body 110 .

[0089] Please refer to Figures 1 to 6 In this embodiment, when the roadbed and road surface flatness detection device 100 moves and encounters different road surface flatnesses, the detection wheel 1422 moves up and down according to the unevenness of the road surface. The connection rod 1421 is transmitted, causing the connection rod 1421 to perform a telescopic action in the movable hole 110a.

[0090] The telescopic movement of the connecting rod 1421 affects the position of the entire movable assembly 140, especially the movement of the light-transmitting hole 140a relative to the first laser transmitter 120 and the first laser receiver 130, thereby realizing the detection of the road surface flatness.

[0091] Through the telescopic connection between the movable hole 110a and the connecting rod 1421, the roadbed and pavement flatness detection device 100 can flexibly adapt to various road conditions, thereby ensuring the accuracy and reliability of the detection.

[0092] The roadbed and pavement smoothness detection device 100 can quickly respond to changes in the road surface, reduce detection delays caused by uneven road surface, and significantly improve the efficiency of the detection process.

[0093] In at least one embodiment of the present application, an abutment plate 1423 is provided at one end of the connecting rod 1421 away from the detection wheel 1422 , one end of the elastic member 141 abuts against the main body 110 , and the other end is sleeved on the connecting rod 1421 and abuts against the abutment plate 1423 .

[0094] Please refer to Figures 1 to 6 In this embodiment, when the roadbed and road surface flatness detection device 100 encounters unevenness on the road surface, the detection wheel 1422 moves up and down, thereby causing the connecting rod 1421 to move relative to the main body 110. This causes the elastic member 141 sleeved on the connecting rod 1421 to deform. One end of the elastic member 141 is fixed to the main body 110, and the other end is fixed to the connecting rod 1421.

[0095] Since one end of the elastic member 141 is fixed to the main body 110 and the other end is connected to the connecting rod 1421 through the abutment plate 1423, the deformation of the elastic member 141 directly affects the position of the connecting rod 1421, especially the relative position of the light-transmitting hole 140a, thereby adjusting whether the laser can pass through the light-transmitting hole 140a to reach the first laser receiver 130.

[0096] By precisely controlling the interaction between the elastic member 141 and the abutment plate 1423 , it is possible to very sensitively respond to slight changes in the road surface, thereby improving the accuracy of road surface flatness detection.

[0097] The roadbed and pavement flatness detection device 100 can better adapt to various road conditions. No matter whether the road surface is convex or concave, the roadbed and pavement flatness detection device 100 can accurately measure and record.

[0098] The interaction between the abutment plate 1423 and the elastic member 141 ensures that the movement of the connecting rod 1421 is stable and controllable when encountering different road conditions, thereby reducing the error caused by uneven road conditions.

[0099] An abutment plate 1423 is provided at one end of the connecting rod 1421 away from the detection wheel 1422. The abutment plate 1423 is a key part of the interaction between the elastic member 141 and the connecting rod 1421, providing a stable abutment point for transmitting force and movement.

[0100] One end of the elastic member 141 directly contacts the main body 110, and the other end is sleeved on the connecting rod 1421 and contacts the contact plate 1423. The elastic member 141 can effectively adjust the position of the connecting rod 1421 (and the detection wheel 1422) through its deformation when the detection wheel 1422 experiences a road surface change.

[0101] In at least one embodiment of the present application, a mounting plate 1424 is provided at one end of the connecting rod 1421 close to the detection wheel 1422;

[0102] The roadbed and pavement flatness detection device 100 further includes:

[0103] A second laser receiver 150 is disposed on a side of the mounting plate 1424 close to the first laser transmitter 120;

[0104] The movable component 140 moves toward the side close to the main body 110 so that the second laser receiver 150 receives the laser emitted by the first laser emitter 120 to determine that the ground is protruding.

[0105] Please refer to Figures 1 to 6In this embodiment, when the roadbed and pavement flatness detection device 100 moves and encounters a ground protrusion, the movable assembly 140 (including the connecting rod 1421, the detection wheel 1422 and the mounting plate 1424) will move to the side close to the main body 110. This allows the second laser receiver 150 to directly receive the laser emitted by the first laser transmitter 120.

[0106] The second laser receiver 150 receives the laser signal, and the roadbed and pavement flatness detection device 100 detects the protruding part of the road surface. This is because on a flat road surface, the laser emitted by the first laser emitter 120 usually does not directly irradiate the second laser receiver 150. Only when the roadbed and pavement flatness detection device 100 encounters a protrusion on the ground will it drive the movable component 140 to move toward the side close to the main body 110.

[0107] By adding the second laser receiver 150, the raised portion of the road surface can be detected more accurately, thereby improving the detection accuracy of the entire system.

[0108] The roadbed and pavement flatness detection device 100 can adapt to various complex road conditions and can effectively detect whether it is flat, convex or concave.

[0109] Compared with traditional linear ruler inspection methods, the use of laser technology can significantly improve the speed and efficiency of inspection, especially when dealing with large areas of road surface.

[0110] Since the first laser receiver 130 and the second laser receiver 150 can automatically identify the laser signal, the need for manual intervention is reduced, the operation is simpler, and the technical requirements of the operator are reduced.

[0111] It should be further explained that if neither the first laser receiver 130 nor the second laser receiver 150 receives the laser, it is determined to be a depression.

[0112] A mounting plate 1424 is provided at one end of the connecting rod 1421 close to the detection wheel 1422, providing a position for fixing the second laser receiver 150.

[0113] The second laser receiver 150 is disposed on the mounting plate 1424 , close to one side of the first laser transmitter 120 , allowing the second laser receiver 150 to directly receive the laser from the first laser transmitter 120 .

[0114] In at least one embodiment of the present application, the movable component 140 moves to a side away from the main body 110 so that the second laser receiver 150 and the first laser receiver 130 do not receive the laser emitted by the first laser transmitter 120, so as to determine that the ground is sunken.

[0115] In this embodiment, when the roadbed and pavement flatness detection device 100 passes through a sunken part of the ground, due to the sinking of the ground, the movable component 140 (including the connecting rod 1421, the detection wheel 1422, etc.) will move downward, that is, move away from the main body 110.

[0116] The laser emitted by the first laser transmitter 120 cannot be received by the first laser receiver 130 and the second laser receiver 150. Because the straight path of laser emission and reception is affected by the position change of the movable component 140 in the ground depression, the laser path is blocked.

[0117] The depression of the road surface can be judged very accurately.

[0118] Since the road condition is determined by the presence or absence of laser, the detection efficiency is improved, especially when moving at high speeds.

[0119] It can respond to slight changes in the road surface and adapt to various road conditions, thereby increasing the application scope of the roadbed and road surface flatness detection device 100.

[0120] In at least one embodiment of the present application, a sealed movable cavity 110 b is further provided on the main body 110 , the movable cavity 110 b is communicated with the movable hole 110 a , and one end of the connecting rod 1421 is movably received in the movable cavity 110 b .

[0121] Please refer to Figures 1 to 6 In this embodiment, when the roadbed and pavement flatness detection device 100 moves and encounters different road surface conditions (such as flat, convex or concave), the connecting rod 1421 will move accordingly. The movement may be extension or contraction, depending on the specific conditions of the road surface.

[0122] The movement of the connecting rod 1421 allows the movable assembly 140 (such as the detection wheel 1422 and the light-transmitting hole 140a, etc.) to adapt to changes in the road surface, while a portion of the connecting rod 1421 is always in the sealed movable cavity 110b, ensuring its stability and protection.

[0123] By protecting a portion of the connecting rod 1421 in the sealed active cavity 110b, factors such as dust and moisture that may damage the device are effectively prevented, thereby extending the service life of the device.

[0124] The sealing of the movable chamber 110b protects the connecting rod 1421 from external influences, ensures the accuracy of its movement, and thus maintains the accuracy of the detection result.

[0125] The main body 110 is provided with a sealed active cavity 110 b, and the active cavity 110 b is used to protect the internal components from the influence of the external environment, such as dust, moisture, etc.

[0126] The movable cavity 110b is in communication with the movable hole 110a, allowing the connecting rod 1421 to move freely in the cavity while remaining isolated from the external environment.

[0127] In at least one embodiment of the present application, the movable components 140 are arranged in multiple rows, and the movable components 140 in each row are arranged at equal intervals.

[0128] Please refer to Figures 1 to 6 In this embodiment, when the roadbed and pavement flatness detection device 100 moves along the road surface, each row of movable components 140 independently responds to the flatness or unevenness under the road surface. Since the movable components 140 are arranged in multiple rows and at equal intervals, this ensures that the roadbed and pavement flatness detection device 100 can cover a wider road surface area at any given time.

[0129] When encountering an uneven road surface, the movable components 140 of different arrangements will move independently according to the road surface conditions at the specific location, and the movement process will be transmitted to the detection system of the roadbed and pavement flatness detection device 100, thereby allowing the system to accurately identify the flatness of the road surface or the specific uneven location.

[0130] By adding multiple rows of movable components 140 arranged at equal intervals, the roadbed and pavement flatness detection device 100 can more accurately map the condition of the road surface, thereby improving the accuracy and reliability of the detection results.

[0131] The multiple rows of movable components 140 expand the coverage of the detection, so that the roadbed and pavement flatness detection device 100 can simultaneously evaluate a wider road surface area, thereby improving the detection efficiency.

[0132] The equally spaced layout of the active components 140 provides uniform data collection points, which helps to generate more consistent and continuous road surface roughness data, providing more accurate reference information for road maintenance and repair.

[0133] This enables the roadbed and pavement flatness detection device 100 to better adapt to road surfaces of different widths and complexities, including road surfaces with a variety of different concavities and convexities.

[0134] In at least one embodiment of the present application, a control display terminal 112 is provided on the main body 110 , and the control display terminal 112 is electrically connected to the first laser emitter 120 and the first laser receiver 130 .

[0135] Please refer to Figures 1 to 6In this embodiment, when the roadbed and pavement flatness detection device 100 moves along the road surface and performs flatness detection, the first laser transmitter 120 transmits laser to the opposite first laser receiver 130. The unevenness of the road surface will cause the laser path to change, so that the second laser receiver 150 or the first laser receiver 130 receives the signal, or the first laser receiver 130 and the second laser receiver 150 cannot receive the laser signal.

[0136] These signals are transmitted to the control display terminal 112 via an electrical connection, and the control display terminal 112 processes the data and visually displays the detection results to the operator.

[0137] By displaying the detection data in real time, the control display terminal 112 reduces the time delay of data processing, making the road detection and evaluation work faster and more efficient.

[0138] The electrical connection enables the control display terminal 112 to be used to remotely adjust the parameters of the laser transmitter and the receiver, thereby increasing the adaptability and flexibility of the roadbed and pavement smoothness detection device 100 under different road conditions.

[0139] It should be noted that when the roadbed and pavement flatness detection device 100 passes through a concave portion of the road surface, the detection wheel 1422 will drop along with the road surface, causing the connecting rod 1421 and the movable assembly 140 to move away from the main body 110 .

[0140] The laser emitted by the first laser transmitter 120 cannot directly reach any laser receiver (the first laser receiver 130 or the second laser receiver 150 ) because the position change of the movable component 140 causes the light-transmitting hole 140 a to deviate from the laser path.

[0141] The information received by the control display terminal 112 indicates that no laser signal is received, thereby determining that there is a depression in the road surface.

[0142] On the flat surface of the road, the detection wheel 1422 remains stable and the movable assembly 140 does not excessively move in any direction of the main body 110 .

[0143] The laser emitted by the first laser emitter 120 passes through the light-transmitting hole 140 a smoothly and is captured by the first laser receiver 130 , while the second laser receiver 150 does not receive the laser.

[0144] The control display terminal 112 displays information that the laser signal is received normally, indicating that the road surface is smooth.

[0145] When the roadbed and pavement flatness detection device 100 encounters a road surface bump, the detection wheel 1422 will rise, pushing the movable component 140 to move in a direction close to the main body 110 .

[0146] The second laser receiver 150 is enabled to receive the laser light from the first laser transmitter 120 because the movement of the movable assembly 140 results in the adjustment of the laser light path.

[0147] The control display terminal 112 receives the information that the second laser receiver 150 receives the laser, thereby determining that there is a bump on the road surface.

[0148] For each road surface condition (depression, flat surface, bump), the control display terminal 112 will display the detection results in real time, providing intuitive graphical or numerical information.

[0149] Operators can use this information to assess the condition of the road surface and decide if further repairs or treatment measures are needed.

[0150] The above is only an implementation method of the present application. It should be pointed out that a person skilled in the art can make improvements without departing from the inventive concept of the present application, but these improvements are within the scope of protection of the present application.
