Description

Technical Field

[0001] The utility model relates to the technical field of pavement evenness measurement, and particularly relates to a pavement evenness detection device for epoxy asphalt pavement paving on a steel bridge deck. Background Technique

[0002] After bridge construction, mainly for steel bridges, in order to facilitate vehicle passage, it is necessary to lay epoxy asphalt on the surface of the bridge to increase the durability of the bridge deck, reduce noise or improve driving comfort, which helps to disperse the load and reduce the wear of the steel bridge deck.

[0003] After laying epoxy asphalt to form a pavement, according to the requirements of relevant technical specifications in China, it is necessary to detect the evenness of the pavement in order to control the quality of the pavement and avoid unevenness of the pavement affecting vehicle driving. At present, there are many ways to measure pavement evenness, such as the 3m straightedge method, the continuous evenness meter method, the laser evenness meter method, etc.

[0004] Because the equipment used in the 3m straightedge method is relatively simple, therefore, the 3m straightedge method is usually used to complete the detection of pavement evenness. The equipment used in the 3m straightedge method is mainly a 3m long straightedge plate. The 3m long straightedge is placed flat on the epoxy asphalt surface, and the maximum gap between the straightedge and the epoxy asphalt surface is measured. For example, on a 3m long epoxy asphalt surface, it is measured every 1m, and the maximum value is taken as the evenness index. The 3m straightedge plate can refer to a quality detection device for a plastic runway disclosed in a Chinese patent with the patent number CN218842801U, which includes an intermediate ruler and side rulers. The intermediate ruler and the side rulers are both arranged horizontally. Quick-release components are installed horizontally on both sides of the intermediate ruler; the side rulers are respectively located at both ends of the intermediate ruler. The ends of the side rulers at both positions close to each other are detachably connected to the intermediate ruler through the quick-release components, and part of the quick-release components are installed at the end positions of the side rulers. When using the 3m straightedge plate provided by the above structure to detect pavement evenness, it is convenient to store and transfer according to needs, and avoid the problem that the length of the straightedge plate cannot be adjusted and affects carrying.

[0005] Although the 3m straightedge plate provided by the above patent is convenient to carry, and after it is placed flat on the road surface, the staff holds the measuring ruler to measure the gap between the straightedge plate and the road surface. However, this measurement method has a large error, because the staff can only measure several gaps according to experience when holding the measuring ruler. The data obtained through measurement is very likely not the data at the maximum gap. Then, based on the measurement results, the maximum gap between the straightedge and the road surface is evaluated, and after the evaluation, the evenness detection of this part of the road surface is completed. This will cause a deviation between the maximum gap obtained by measurement and the actual maximum gap, and it is impossible to obtain a more accurate detection result. Content of the Utility Model

[0031] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "connection", "connection", "fixation" and other terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0032] The following will be further described in conjunction with the drawings and specific embodiments:

[0033] Embodiment 1

[0034] In order to solve the problem that there is a deviation between the detection result obtained by using the existing straightedge board to detect the road surface flatness and the actual result, in this embodiment, a measuring component is installed on the existing straightedge board. After the three-meter straightedge board is placed flat on the road surface, the staff can push the measuring component to move, so as to comprehensively measure the road surface covered by the three-meter straightedge board, and accurately obtain the data of the maximum gap. The specific structure of the measuring component will be introduced below. Since the three-meter straightedge board is an existing technology and will not be described, hereinafter, the three-meter straightedge board will be collectively referred to as straightedge board 1.

[0035] As Figure 1 , Figure 2 , Figure 7 shown, the measuring component includes a first bracket 2, a second bracket 3, rollers 4 and a measuring mechanism 5. The first bracket 2 and the second bracket 3 are adjustably spliced and connected, and their lower ends are distributed on both sides of the straightedge board 1. There are two rollers 4, and the two rollers 4 are arranged on the front and rear sides of the lower ends of the first bracket 2 and the second bracket 3, and are in rolling contact with the straightedge board 1 at the same time. Therefore, with the cooperation of the first bracket 2, the second bracket 3 and the rollers 4, the measuring component is stably and movably installed relative to the straightedge board 1, so as to control the movement of the measuring component under the action of an external force, which facilitates the continuous detection of the gap under the straightedge board 1. The measuring mechanism 5 is arranged on the first bracket 2 or the second bracket 3, and it includes a drawing board 51 and a drawing device 52. The drawing device 52 is arranged to move up and down on the side of the drawing board 51. During the movement of the measuring component, the bottom of the drawing device 52 is always in contact with the road surface, and a vertical line can be formed on the drawing board 51 at the same time. The length of this line is the data of the maximum gap. Through the operation of the measuring component, the continuous measurement of the gap under the straightedge board 1 is realized, and it is not necessary for the staff to select the points to be measured, which provides support for quickly completing the measurement of the road surface flatness.

[0036] As Figure 3 , Figure 5 shown, in order to stably install the measuring component on the straightedge board 1, the first bracket 2 includes a first vertical plate 21 and a first splicing plate 22, the second bracket 3 includes a second vertical plate 31 and a second splicing plate 32. The first vertical plate 21 and the second vertical plate 31 are the same, and the first splicing plate 22 and the second splicing plate 32 are arranged on the side walls of the first vertical plate 21 and the second vertical plate 31 close to each other. At the same time, the first splicing plate 22 is inserted into the second splicing plate 32. Therefore, the first vertical plate 21 and the second vertical plate 31 are stably connected in parallel.

[0037] As Figure 3 , Figure 5 , Figure 6As shown, in addition, a first support plate 24 and a second support plate 34 are respectively and fixedly arranged on the sides of the first vertical plate 21 and the second vertical plate 31. A central shaft 42 is penetrated through the roller 4. Both ends of the central shaft 42 penetrate through the first support plate 24 and the second support plate 34 respectively. A first spring 41 is sleeved on the central shaft 42. The first spring 41 is in a compressed state, and both ends are in contact with the roller 4 bearing and the support plate respectively. Under the action of the first spring 41, the roller 4 is located at the middle position between the first vertical plate 21 and the second vertical plate 31. At the same time, the first vertical plate 21 and the second vertical plate 31 are vertically arranged on the scale plate 1, providing support for the staff to push the measuring component to move on the scale plate 1 and providing continuous measurement with a complete gap.

[0038] As Figure 3 , Figure 4 , Figure 5 As shown, in order to reduce the resistance of the first vertical plate 21 and the second vertical plate 31 moving relative to the scale plate 1, mounting grooves 25 are arranged at the lower ends of the side walls of the first vertical plate 21 and the second vertical plate 31 that are close to each other. A curved surface groove 26 is arranged on the side wall of the mounting groove 25. The central angle of the curved surface groove 26 is 180°. A limiting plate 28 is arranged at the mounting groove 25. A curved hole is arranged on the limiting plate 28. The center of the larger diameter opening of the curved hole coincides with the center of the curved surface groove 26. Therefore, the cooperation of the curved hole and the curved surface groove 26 can limit the stable placement of the sphere 27. At the same time, the sphere 27 protrudes from the limiting plate 28 and contacts the scale plate 1. Therefore, the rolling of the sphere 27 can reduce the resistance of the vertical plate and the scale plate 1 moving relative to each other. In order to stably install the limiting plate 28 on the vertical plate, a threaded column 29 is fixedly arranged on the side of the limiting plate 28. The threaded column 29 penetrates through the vertical plate and a nut is threadedly sleeved at the end. Therefore, the limiting plate 28 can be stably installed on the vertical plate under the cooperation of the nut and the threaded column 29.

[0039] As Figure 3 , Figure 5 As shown, in order to be able to adjust the relative positions of the first support 2 and the second support 3 according to requirements and adapt to scale plates 1 of different widths, the first support 2 further includes an adjusting screw rod 23. The adjusting screw rod 23 is connected through a bearing and penetrates through the first vertical plate 21. The second support 3 further includes an internally threaded tube 33. The internally threaded tube 33 is vertically installed on the second vertical plate 31 and is threadedly sleeved on the adjusting screw rod 23. Therefore, by rotating the adjusting screw rod 23, the relative positions of the first support 2 and the second support 3 can be adjusted, and further the width of the measuring component can be adjusted so as to stably install it on the scale plate 1.

[0040] As Figure 8As shown in the figure, in order to draw lines on the drawing board 51 and at the same time stably install the drawing board 51 relative to the vertical board, a frame body 512 is arranged on the outer side of the drawing board 51. A limiting tube 513 is fixedly arranged on the side of the frame body 512, and a connecting rod 511 is fixedly arranged on the other side. The end of the connecting rod 511 is provided with a thread. Therefore, the connecting rod 511 penetrates through the first vertical board 21 or the second vertical board 31, and a nut is sleeved on the threaded end. Therefore, the frame body 512 can be stably installed relative to the vertical board.

[0041] As Figure 9 shown in the figure, in addition, the line-drawing device 52 includes a top rod 521, a bottom rod 525 and a paintbrush 523. The top rod 521 is arranged in an L-shaped structure. The main part of the bottom rod 525 is inclined, that is, the main part of the bottom rod 525 has an angle with the horizontal line. Upper clamping plates 522 and lower clamping plates 524 are respectively fixedly arranged at the adjacent ends of the top rod 521 and the bottom rod 525. The upper clamping plates 522 and the lower clamping plates 524 are connected by bolts. The paintbrush 523 penetrates through the space formed by the upper clamping plates 522 and the lower clamping plates 524. At the same time, a disc body is arranged on the top rod 521 and penetrates through the limiting tube 513 at the top. A second spring 53 is sleeved on the top rod 521. The second spring 53 is in a compressed state and is in contact with the limiting tube 513 and the disc body at both ends respectively. Under the action of the second spring 53, only the end of the bottom rod 525 contacts the road surface. Because the second spring 53 can be telescopic and the top rod 521 penetrates through the limiting tube 513, when the road surface is uneven, the bottom rod 525 and the top rod 521 drive the paintbrush 523 to lift and lower synchronously. At the same time, the paintbrush 523 draws vertical lines on the drawing board 51. The vertical lines are the height differences of the paintbrush 523 rising and falling when walking along the uneven road surface, that is, the maximum gap formed between the scale board 1 and the road surface.

[0042] Embodiment 2

[0043] As Figure 10 、 Figure 11 、 Figure 12 shown in the figure, on the basis of Embodiment 1, in order to realize the storage and convenient carrying of the scale board 1, the scale board 1 includes a first board body 11 and a second board body 12. There are two first board bodies 11, which are respectively arranged at both ends of the second board body 12. In addition, buckling plates 13 are arranged at the ends of the first board bodies 11 close to each other. Buckling grooves 14 are arranged on both end faces of the second board body 12. The buckling plates 13 and the buckling grooves 14 are both arranged in an uneven structure. At the same time, the buckling plates 13 are installed in the buckling grooves 14. In addition, an anti-slip layer is arranged on the contact surface of the buckling plates 13 and the buckling grooves 14. Through the anti-slip layer, the buckling plates 13 are stably installed in the buckling grooves 14. In addition, with the cooperation of the buckling plates 13 and the buckling grooves 14, the first board body 11 and the second board body 12 are stably connected, and at the same time, it provides convenience for quick disassembly and assembly according to needs.

[0044] The above is only the preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model.
