Description

Technical Field

[0001] This invention relates to the field of bridge deck inspection technology, specifically to a device and method for detecting the flatness of bridge deck pavement construction. Background Technology

[0002] Most bridges are constructed using concrete, and the bridge deck, as the part of the bridge that directly bears the loads of vehicles and pedestrians, has its smoothness directly affecting vehicles, roads, and people. It impacts vehicle lifespan, increases travel time, and raises the likelihood of traffic accidents. With repeated vehicle use, it can also damage the bridge deck structure, increasing subsequent maintenance costs. Currently, bridge deck smoothness testing is generally done manually, with manual marking. This results in slow, time-consuming, and labor-intensive testing, sometimes affecting accuracy. Although some bridge deck smoothness testing devices can automatically identify bumps and depressions, using the same color for marking can easily lead to identification errors and operational mistakes by construction workers.

[0003] Therefore, the present invention provides a device and method for detecting the flatness of bridge deck pavement construction to solve the above problems. Summary of the Invention

A water tank 100 is connected to the first mixing tank 103 and is used to dilute the concentrated pigment 1 flowing into the first mixing tank 103; A second mixing tank 104 is provided below the second pigment tank 102, and the second pigment tank 102 is connected to the second mixing tank 104. A water tank 100 is connected to the second mixing tank 104 and is used to dilute the concentrated pigment 2 flowing into the second mixing tank 104.

[0040] A first stirring blade 107 and a second stirring blade 108 are rotatably disposed inside the first mixing chamber 103 and the second mixing chamber 104, respectively. The rotational axis of the first stirring blade 107 extends upward to the motor housing 112 at the upper end of the vehicle body 1. The first motor 113 is fixed to the upper part of the motor housing 112. The first gear 110, the second gear 111, and the third gear 114 are all located at the lower part of the motor housing 112, with the third gear 114 located between the first gear 110 and the second gear 111. The output shaft of the first motor 113 is fixedly connected to the third gear 114, and the lower part of the third gear 114 is connected to the vehicle body 1. The upper end of body 1 is rotatably connected, and the two ends of the third gear 114 are respectively meshed with the first gear 110 and the second gear 111. The second gear 111 is fixedly connected to the rotating shaft of the second stirring blade 108, and the first gear 110 is fixedly connected to the rotating shaft of the first stirring blade 107. When the first motor 113 is started, it can simultaneously drive the first stirring blade 107 and the second stirring blade 108 to rotate at the same time. During the process of the vehicle body 1 moving to detect the flatness of the bridge deck pavement layer, it can stir and dilute concentrated pigment one and concentrated pigment two, so that concentrated pigment one and concentrated pigment two are mixed evenly with water.

[0041] Multiple connecting rings 106 are provided on the upper part of the end face of the receiving groove of the vehicle body 1, and the connecting rings 106 are fixedly connected to the upper end of the fixing head 22; multiple sliding rings 105 are provided in the middle of the end of the vehicle body 1 near the receiving groove, and the sliding rings 105 are slidably connected to the middle of the detection tube 21 to limit the vertical direction of the detection tube 21; four wheels 109 are also rotatably provided on the vehicle body 1, and the four wheels 109 are located at the bottom of the vehicle body 1 in a rectangular arrangement to facilitate the vehicle body 1 to move along the bridge surface for detection.

[0042] The upper end of the detection cylinder 21 is inserted into the lower end of the fixing head 22. Multiple detection cylinders 21, multiple fixing heads 22, and multiple connecting levers 23 correspond one-to-one with multiple connecting rings 106. Multiple detection cylinders 21, multiple fixing heads 22, and multiple connecting levers 23 correspond one-to-one with multiple sliding rings 105. A threaded post is provided at the upper end of the fixing head 22, passing through the connecting rings 106 from bottom to top and locked with a nut. This arrangement allows for adjustment of the position of the fixing head 22 and facilitates replacement of the detection component 2. A sliding groove is provided inside the fixing head 22. The upper part of the detection cylinder 21 is inserted into the groove and slidably connected to the fixing head 22 through the sliding groove. A first spring 221 is fixedly installed inside the sliding groove, with its lower end fixed to the upper end of the detection cylinder 21. The connection is as follows: an electromagnetic plate 1 is fixedly installed at the lower end of the fixing head 22; a detection head 211 is installed at the lower part of the detection cylinder 21 for detecting uneven depressions or protrusions on the bridge surface pavement; a boss 212 is installed at the upper part of the detection cylinder 21, and an electromagnetic plate 22 is fixedly installed at the upper end of the boss 212. When the electromagnetic plate 1 and the electromagnetic plate 22 are energized, the boss 212 is attracted and connected to the lower end of the fixing head 22, and the detection cylinder 21 does not contact the bridge surface and does not perform detection; when the electromagnetic plate 1 and the electromagnetic plate 22 are de-energized, the boss 212 is separated from the lower end of the fixing head 22, allowing the detection cylinder 21 to contact the bridge surface for detection. The electromagnetic plate is designed to prevent the vehicle body 1 from dragging the detection cylinder 21 and continuously rubbing against the ground during normal driving, which would damage the detection cylinder 21 and reduce its service life.

[0043] A support shaft 24 passes through the middle of multiple connecting levers 23. The two ends of the support shaft 24 are fixedly connected to both sides of the vehicle body 1. The middle of each connecting lever 23 is rotatably connected to the support shaft 24. Multiple connecting levers 23 are evenly spaced along the support shaft 24 and are located in a receiving groove in the vehicle body 1. One end of each connecting lever 23 is hinged to the middle of the detection cylinder 21, and the other end is hinged to the marking assembly 3. When the device is in use, the detection head 211 detects uneven depressions on the bridge deck pavement, causing the detection cylinder 21 to slide downwards, thus driving the connecting levers 23... When the probe 211 detects an uneven depression on the bridge surface, the probe 21 rotates upward, causing the end of the connecting lever 23 connected to the marking component 3 to rotate upward, thus causing the marking component 3 to release pigment one and mark the uneven protrusions on the bridge surface. When the probe 211 detects an uneven depression on the bridge surface pavement, the probe 21 rotates upward, causing the end of the connecting lever 23 connected to the probe 21 to rotate upward, thus causing the end of the connecting lever 23 connected to the marking component 3 to rotate downward, thus causing the marking component 3 to release pigment two and mark the uneven protrusions on the bridge surface.

[0044] The marking assembly 3 includes a connecting pipe 31, a collecting cylinder 32, a first conveying pipe 33, a second conveying pipe 34, a discharge box 35, a discharge head 36, and a second motor 37. Two connecting pipes 31 are provided, corresponding to the first mixing box 103 and the second mixing box 104 respectively. The upper ends of the two connecting pipes 31 are connected to the lower ends of the first mixing box 103 or the second mixing box 104, and the lower ends are connected to the upper ends of the collecting cylinder 32. Each connecting pipe 31 is equipped with a switch valve to prevent pigment one or pigment two from flowing into the collecting cylinder 32 when the device is not in use. The collecting cylinder 32 has two chambers, receiving chamber one and receiving chamber two, used to receive pigments flowing out of the first mixing box 103 or the second mixing box 104 respectively. A second spring 321 is fixedly installed in receiving chamber one and receiving chamber two respectively, and a sliding spring 321 is installed in the middle of receiving chamber one. A slider 322 has a second spring 321 installed at the lower part of its receiving cavity, with the upper end of the second spring 321 fixedly connected to the slider 322. A slider 323 is slidably installed in the middle of the receiving cavity, with the second spring 321 installed at the upper part of the receiving cavity, and the lower end of the second spring 321 fixedly connected to the slider 323. Both sliders 322 and 323 can slide up and down. Slider 322 has a flow hole 1 running through it from top to bottom, for pigment 1 to flow into the receiving cavity 1 through the connecting pipe 31. Slider 323 has a flow hole 2 running through it from top to bottom, for pigment 2 to be fed into the receiving cavity 2 through the connecting pipe 31. The lower end of the receiving cavity is connected to a first conveying pipe 33, through which pigment 1 can be conveyed to the discharge box 35. The lower end of the receiving cavity is connected to a second conveying pipe 34, through which pigment 2 can be conveyed to the discharge box 35.

[0045] The sleeve 324 is fitted onto the outside of the collecting cylinder 32, and is located in the middle of the collecting cylinder 32. The sleeve 324 has a lug on its exterior, which is hinged to the connecting lever 23. The sleeve 324 can slide up and down along the outside of the collecting cylinder 32. Adjusting plate 325 and adjusting plate 326 extend inwards through the pipe wall of the collecting cylinder 32 on both sides of the middle of the sleeve 324. The sleeve 324 can prevent leakage from the collecting cylinder 32 through a sealing ring. Adjusting plate 325 is located in the middle of the receiving cavity 1, and adjusting plate 326 is located in the middle of the receiving cavity 2. The lower surface of adjusting plate 325 is in contact with or separate from slider 322. The surface of the first regulating plate 325 abuts against or separates from the upper thickened tube wall of the first receiving cavity, and the regulating plate 325 can slide up and down along the tube wall; the upper surface of the second regulating plate 326 is in contact with or separate from the second slider 323, and the lower surface abuts against or separates from the lower thickened tube wall of the second receiving cavity, and the regulating plate 326 can slide up and down along the tube wall. The sliding distance between the upper thickened tube wall of the first receiving cavity and the lower thickened tube wall of the second receiving cavity is the sliding distance between the regulating plate 325 and the regulating plate 326; the regulating plate 325 and the regulating plate 326 are respectively provided with through holes 1 and 2, with through hole 1 located on one side of flow hole 1 and through hole 2 located on one side of flow hole 2.

[0046] When the probe cylinder 21 encounters a concave point, the end of the connecting lever 23 connected to the collecting cylinder 32 moves upward, pushing the sleeve 324 to move upward, thereby causing the adjusting plate 325 and the adjusting plate 326 to move upward along the inner wall of the collecting cylinder 32. The adjusting plate 326 pushes the slider 323 to move upward, and the slider 323 squeezes the second spring 321 in the receiving cavity. At this time, the adjusting plate 325 and the slider 322 in the receiving cavity separate, so that the pigment 1 flowing into the receiving cavity 1 can flow through the through hole 1 and the flow hole 1 into the first conveying pipe 33 below, and reach the discharge box 35 through the first conveying pipe 33. When the probe cylinder 21 encounters a protrusion, the end of the connecting lever 23 connected to the collecting cylinder 32 moves downward, pushing the sleeve 324 downward, thereby causing the adjusting plate 1 325 and the adjusting plate 2 326 to move downward along the inner wall of the collecting cylinder 32. The adjusting plate 1 325 squeezes the second spring 321 of the receiving cavity 1, and the adjusting plate 1 325 pushes the slider 1 322 downward. At this time, the adjusting plate 2 326 and the slider 2 323 in the receiving cavity 2 separate, so that the pigment 2 flowing into the receiving cavity 2 can flow into the lower second conveying pipe 34 through the through hole 2 and the flow hole 2, and reach the discharge box 35 through the second conveying pipe 34.

[0047] When the bridge surface to be inspected meets the requirements, the probe 211 contacts the bridge surface, making the connecting lever 23 horizontal. The sleeve 324 is located in the middle of the collecting cylinder 32. The adjusting plate 1 325 is in contact with the slider 1 322, and the adjusting plate 2 326 is in contact with the slider 2 323. Pigment 1 flowing into the receiving cavity 1 cannot pass through the through hole 1 and the flow hole 1 and then flows into the first conveying pipe 33 below. Pigment 2 flowing into the receiving cavity 2 cannot pass through the through hole 2 and flows into the second conveying pipe 34 below.

[0048] The discharge box 35 can be a cylindrical box. A second motor 37 is fixedly installed on the upper surface of the discharge box 35. The output shaft of the second motor 37 passes through the discharge box 35, extends to the bottom of the discharge box 35, and is fixedly connected to the discharge head 36. The discharge box 35 and the discharge head 36 are rotatably connected. The discharge box 35 is provided with a first partition 353 and a second partition 354. The discharge box 35, the first partition 353, and the second partition 354 divide the interior of the discharge box 35 into three placement chambers in sequence: placement chamber one, placement chamber two, and placement chamber three. Placement chamber one, placement chamber two, and placement chamber three are not connected. The output end of the first conveying pipe 33 is located at the upper end of placement chamber one and is connected to placement chamber one. A first discharge hole 351 is provided through the lower end of placement chamber one. Placement chamber two is used for the output shaft of the second motor 37 to pass through. The output end of the second conveying pipe 34 is located at the upper end of placement chamber three and is connected to placement chamber three. A second discharge hole 352 is provided through the lower end of placement chamber three.

[0049] The discharge head 36 can be a circular plate. A first discharge port 361 and a second discharge port 362 are provided through the discharge head 36. The first discharge hole 351, the second discharge hole 352, the first discharge port 361, and the second discharge port 362 are arranged in a circle. The angle between the first discharge hole 351 and the second discharge hole 352 and the center of the circle is 120°, and the angle between the first discharge port 361 and the second discharge port 362 and the center of the circle is 180°. That is, when the first discharge port 361 corresponds to the first discharge hole 351, the second discharge port 362 and the second discharge hole 352 will not correspond simultaneously. Multiple flow holes are provided on the first discharge port 361 and the second discharge port 362, and these flow holes are arranged in different shapes. In this embodiment, the multiple flow holes on the first discharge port 361 can be arranged in a T-shape, and the multiple flow holes on the second discharge port 362 can be arranged in a grid pattern, for more intuitive differentiation of pigment one and pigment two marking the bridge surface. The unevenness of the paving layer has concave and convex points. The first discharge port 361 is used for pigment one to flow into the first placement chamber of the discharge box 35, and the second discharge port 362 is used for pigment two to flow into the third placement chamber of the discharge box 35. When the probe tube 21 encounters a convex point, the second motor 37 is started. The output shaft of the second motor 37 drives the discharge head 36 to rotate until the second discharge port 362 corresponds to the second discharge hole 352. At this time, the first discharge hole 351 does not correspond to the first discharge port 361, and pigment two can flow out through the second discharge hole 352 and the second discharge port 362. When the probe tube 21 encounters a concave point, the second motor 37 is started. The output shaft of the second motor 37 drives the discharge head 36 to rotate until the first discharge hole 351 corresponds to the first discharge port 361. At this time, the second discharge port 362 does not correspond to the second discharge hole 352, and pigment one can flow out through the first discharge hole 351 and the first discharge port 361.

[0050] The present invention also provides a method for detecting the flatness of bridge deck pavement construction using the above-mentioned bridge deck pavement construction flatness detection device, comprising the following steps:

[0051] S1: Place the bridge deck pavement construction flatness detection device on the bridge surface to be tested. De-energize the lower electromagnetic plate 1 of the fixed head 22 and the upper electromagnetic plate 2 of the boss 212, so that the detection cylinder 21 is released from the fixed head 22 and the detection head 211 contacts the bridge surface. Start the first motor 113 to drive the first stirring blade 107 and the second stirring blade 108 to stir, and drive the vehicle body 1 to travel along the bridge surface to be tested.

[0052] S2: If an uneven depression is encountered on the bridge surface, the corresponding detection cylinder 21 slides downward, the connecting lever 23 drives the sleeve 324 to move upward, and drives the adjusting plate 1 325 and adjusting plate 2 326 to move upward along the inner wall of the collecting cylinder 32. The adjusting plate 2 326 pushes the slider 2 323 to move upward, so that the adjusting plate 1 325 and the slider 1 322 separate. Pigment 1 reaches the discharge box 35 through the first conveying pipe 33. At the same time, the second motor 37 is started. The output shaft of the second motor 37 drives the discharge head 36 to rotate until the first discharge hole 351 corresponds to the first discharge port 361. Pigment 1 can flow out through the first discharge hole 351 and the first discharge port 361 to mark the uneven depression on the bridge surface.

[0053] S3: If an uneven bump is encountered on the bridge surface, the corresponding detection cylinder 21 slides upward, and the sleeve 324 moves downward through the connecting lever 23, causing the adjusting plate 1 325 and adjusting plate 2 326 to move downward along the inner wall of the collecting cylinder 32. The adjusting plate 1 325 pushes the slider 1 322 downward, causing the adjusting plate 2 326 to separate from the slider 2 323. Pigment 2 reaches the discharge box 35 through the second conveying pipe 34. At the same time, the second motor 37 is started. The output shaft of the second motor 37 drives the discharge head 36 to rotate until the second discharge port 362 corresponds to the second discharge hole 352. Pigment 2 can flow out through the second discharge hole 352 and the second discharge port 362 to mark the uneven bump on the bridge surface.

[0054] S4: Repeat S2-S3 above until all uneven pits or bumps on the bridge surface to be tested are marked. Then turn off the second motor 37 and the first motor 113. The lower electromagnetic plate 1 of the fixed head 22 and the upper electromagnetic plate 2 of the boss 212 are energized and attracted.

[0055] During the above process, water tank 100 and first pigment tank 101 periodically replenish water and concentrated pigment one to first mixing tank 103, and water tank 100 and second pigment tank 102 periodically replenish water and concentrated pigment two to second mixing tank 104.

[0056] When the bridge deck pavement layer flatness testing device is not in use, the switch valves on the two connecting pipes 31 are closed to prevent the electromagnetic plate one at the bottom of the fixed head 22 from being attracted by the electromagnetic plate two at the top of the boss 212, which would cause the connecting lever 23 to be out of horizontal position and cause a large amount of pigment to enter the discharge box 35 along the collecting cylinder 32.

[0057] The bridge deck pavement layer flatness detection device described in this invention can visually observe the locations of abnormal unevenness on the bridge deck pavement layer. The device incorporates multiple sets of marking components, each corresponding to a different detection cylinder. A first and second pigment box are mounted on the vehicle body, each corresponding to two different pigments. The marking components, controlled by levers, allow pigment to flow from the collection cylinder, marking the corresponding uneven depressions or protrusions. The device also features discharge ports of different shapes, enabling more direct observation of uneven areas on the bridge deck, facilitating subsequent construction and correction by construction personnel, and enhancing the performance of the bridge deck structure.

[0058] The present invention also provides a method for testing the flatness of bridge deck pavement construction using the above-mentioned bridge deck pavement construction flatness testing device. By moving the vehicle body on the bridge surface to be tested, the cooperation between the above-mentioned testing components and marking components can directly mark the protrusions or depressions on the bridge surface to be tested, thereby improving the accuracy of the testing results.

[0059] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
