Description

Technical Field

[0001] The invention relates to the technical field of road construction, in particular to a large-angle asphalt pavement thickness control device and a construction method thereof. Background Art

[0002] The roadbed of the road surface is composed of layered structures paved with various mixtures. According to the layers and their functions, it can be divided into surface layer, base layer and functional layer. The surface layer is the structural layer in direct contact with vehicles and the atmosphere. It must bear a large driving load and is affected by precipitation erosion and temperature changes. Generally, its influence gradually weakens with increasing depth. Therefore, the thickness of each layer is closely related to the overall strength of the road. Only when the thickness is guaranteed can the strength of each layer and the overall road surface be guaranteed.

[0003] The quality of roads depends largely on the paving quality of asphalt pavement, and the key to asphalt pavement paving is to control the paving thickness during the construction process. Controlling the paving thickness is to control the compaction quality of the pavement. Only by fully compacting each structural layer can the strength, rigidity, stability and flatness of the pavement be guaranteed, which plays a certain role in preventing early damage to the pavement caused by rutting, thereby extending the service life of the pavement. At the same time, strict control of the paving thickness can timely discover and prevent possible defects or cutting corners during the construction process.

[0004] During the paving process of asphalt pavement, a paver is generally used to control the thickness of asphalt. When the paver is working, it generally uses the method of vibrating the paving board to discharge the material. However, asphalt itself has a certain viscosity, and the unevenness of the roadbed makes the distribution of asphalt itself uneven. Although the asphalt will be rolled by a roller after it falls, since the asphalt itself is laid on the uneven ground with the same thickness, the road surface paved with asphalt is not flat, which causes the asphalt pavement to be easily damaged at the junction of different areas after being rolled by the roller, resulting in poor durability of the asphalt pavement. In addition, at the corner of the road, the paver moves with the corner to form a fan-shaped area, but the existing paver cannot adjust the amount of asphalt poured according to the corner, and will pour the same amount of asphalt on the inside and outside of the corner, resulting in excessive accumulation of asphalt on the inside and too little asphalt on the outside, resulting in uneven thickness of the asphalt pavement. To this end, we provide a large-angle asphalt pavement thickness control device and its construction method to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to make up for the deficiencies of the prior art and to provide a large-angle asphalt pavement thickness control device and a construction method thereof, which solves the problem that the existing paver cannot adjust the pouring amount of asphalt according to the angle.

[0018] A construction method for a large-angle asphalt pavement thickness control device comprises the following steps: asphalt is poured into a placement groove, a spring pushes a stopper to move downward so that a movable wheel contacts the ground, and then a guide wheel drives a bearing box to move; when the movable wheel moves on an uneven ground, the movable wheel can move synchronously with the ups and downs of the ground, a recording pen fixed on the side of the stopper can record the ups and downs of the movable wheel on a recording board, the recording board can transmit the movement amplitude of the movable wheel to an external control device, the external control device can calculate the raised height of the road surface according to the movement data of the movable wheel, and then control a correction component to correct and level the road surface that is higher than the standard height, and control a cleaning component to clean the leveled road surface; wherein, the road surface within a unit length is detected, and the road surfaces with the same height exceeding 80% are set as the standard height.

[0019] The guide wheel on the lower surface of the carrying box at the inner side of the corner is set as the inner wheel, and the guide wheel on the lower surface of the carrying box at the outer side of the corner is set as the outer wheel. When the carrying box moves in a straight line, the speeds of the inner wheel and the outer wheel are the same, and the speed ratio between the outer wheel and the inner wheel is 1:1.

[0047] A construction method of a large-angle asphalt pavement thickness control device comprises the following steps;

[0048] Asphalt is poured into the placement groove 101, and the spring 303 pushes the block 302 to move downward so that the movable wheel 306 contacts the ground, and then the guide wheel 103 drives the carrying box 1 to move. When the movable wheel 306 moves on the uneven ground, the movable wheel 306 can move synchronously with the ups and downs of the ground. The recording pen 304 fixed on the side of the block 302 can record the ups and downs of the movable wheel 306 on the recording board 305. The recording board 305 can transmit the movement amplitude of the movable wheel 306 to the external control device. The external control device can calculate the raised height of the road surface according to the movement data of the movable wheel 306, and then control the correction component 4 to correct and level the road surface that is higher than the standard height, and control the cleaning component 5 to clean the leveled road surface; wherein, the road surface within a unit length is detected, and the road surfaces with the same height exceeding 80% are set as the standard height.

[0049] The guide wheel 103 on the inner side of the lower surface of the carrying box 1 is set as the inner wheel, and the guide wheel 103 on the outer side of the lower surface of the carrying box 1 is set as the outer wheel. When the carrying box 1 moves in a straight line, the rotation speeds of the inner wheel and the outer wheel are the same, and the rotation speed ratio between the outer wheel and the inner wheel is 1:1. When there is a corner on the road surface and the carrying box 1 rotates following the corner of the road surface, the rotation speed of the outer wheel is greater than that of the inner wheel, and the rotation speed ratio between the outer wheel and the inner wheel is 1.2-3.5:1. The external control device controls the adjustment plate 203 near the inner side to close and the adjustment plate 203 near the outer side to open according to the rotation speed ratio between the outer wheel and the inner wheel.

[0050] The speed of the inner wheel can be expressed as: V1 = ω1*R

[0051] The speed of the outer wheel can be expressed as: V2 = ω2*(R+L)

[0052] According to the relationship between vehicle speed V and turning radius R, we have: V = ω1*R = ω2*(R+L)

[0053] The speed ratio between the inner wheel and the outer wheel is obtained: ω2 / ω1=(R / (R+L)).

[0054] The wheelbase of the carrying box 1 is L, the moving speed of the carrying box 1 is V, the rotation speed of the inner wheel is ω1, and the rotation speed of the outer wheel is ω2. Both ω1 and ω2 can be obtained by a rotation speed sensor arranged inside the guide wheel 103.

[0055] Working principle: first place the device in a suitable position, then pour asphalt into the placement groove 101, the spring 303 on the lower surface of the carrying box 1 pushes the block 302 to move downward, so that the movable wheel 306 contacts the ground, and then the carrying box 1 is driven to move through the guide wheel 103. When the movable wheel 306 moves on the uneven ground, the movable wheel 306 can move synchronously with the ups and downs of the ground. The recording pen 304 fixed on the side of the block 302 can record the ups and downs of the movable wheel 306 on the recording board 305. The recording board 305 can transmit the movement amplitude of the movable wheel 306 to the external control device. The external control device can calculate the convex height of the road surface according to the movement data of the movable wheel 306, and then The control correction component 4 corrects and levelles the road surface that is higher than the standard height, and controls the cleaning component 5 to clean the leveled road surface; when the road surface needs to be corrected, the external control device controls the second drive motor 403 to operate, driving the first gear 404 to rotate, the first gear 404 drives the second gear 406 meshing therewith to rotate, the second gear 406 drives the rotating shaft 405 to rotate, the rotating shaft 405 drives the threaded tube 407 to move, the threaded tube 407 drives the placement plate 408 to move, thereby driving the leveling device 409 fixed on the surface of the placement plate 408 to move synchronously, and when the leveling device 409 moves to the specified position, the control device can control the second drive motor 403 to stop operating.

[0056] The guide wheel 103 on the inner side of the lower surface of the carrying box 1 is set as the inner wheel, and the guide wheel 103 on the outer side of the lower surface of the carrying box 1 is set as the outer wheel. When the carrying box 1 moves linearly, the rotation speeds of the inner wheel and the outer wheel are the same, and the rotation speed ratio between the outer wheel and the inner wheel is 1:1. When the road surface turns a corner and the carrying box 1 rotates following the road surface corner, the rotation speed of the outer wheel is greater than that of the inner wheel, and the rotation speed ratio between the outer wheel and the inner wheel is 1.2-3.5:1. The external control device controls the adjustment plate 203 close to the inner side to close and the adjustment plate 203 close to the outer side to open according to the rotation speed ratio between the outer wheel and the inner wheel.

[0057] The speed ratio of the outer wheel and the inner wheel = ω2 / ω1 = (R / (R+L)), where the wheelbase of the carrying box 1 is L, the moving speed of the carrying box 1 is V, the speed of the inner wheel is ω1, and the speed of the outer wheel is ω2. Both ω1 and ω2 can be obtained by the speed sensor arranged inside the guide wheel 103.

[0058] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.

When the movable wheel (306) moves on the uneven ground, the movable wheel (306) can move synchronously with the ups and downs of the ground. The recording pen (304) fixed on the side of the stopper (302) can record the ups and downs of the movable wheel (306) on the recording board (305). The recording board (305) can transmit the movement amplitude of the movable wheel (306) to the external control device. The external control device can calculate the raised height of the road surface based on the movement data of the movable wheel (306), and then control the correction component (4) to correct and level the road surface that is higher than the standard height, and control the cleaning component (5) to clean the leveled road surface.

8. The construction method of the large-angle asphalt pavement thickness control device according to claim 7, It is characterized in that The following steps are involved: The guide wheel (103) on the lower surface of the carrying box (1) located inside the corner is set as the inner wheel, and the guide wheel (103) on the lower surface of the carrying box (1) located outside the corner is set as the outer wheel. When the carrying box (1) moves linearly, the rotation speeds of the inner wheel and the outer wheel are the same, and the rotation speed ratio of the outer wheel to the inner wheel is 1:

1. When a corner appears on the road surface, and the carrying box (1) rotates following the road surface corner, the rotation speed of the outer wheel is greater than the rotation speed of the inner wheel, and the rotation speed ratio of the outer wheel to the inner wheel is 1.2-3.5:

1. The external control device controls the adjustment plate (203) close to the inner side to close and the adjustment plate (203) close to the outer side to open according to the rotation speed ratio of the outer wheel to the inner wheel.
