Description

Technical Field

[0001] The present invention relates to the field of road engineering detection, and particularly to a mobile platform for high-precision pavement evenness detection. Background Art

[0002] The eight-wheel continuous evenness meter is a device designed specifically for measuring the evenness of road surfaces. By rolling its eight wheels on the road surface, it uses high-precision sensors to record key indicators such as road unevenness data. It is easy to operate, measures quickly and accurately, and is widely used in the quality inspection and evaluation of highway engineering. It is a common mobile platform for high-precision pavement evenness detection.

[0003] When detecting the pavement evenness with an eight-wheel continuous evenness meter, due to problems such as equipment looseness, operation specifications, and vibration interference, abnormal measurement data may occur. Generally, data recheck is required, and repeated measurements are carried out along the original path to determine whether the problem is an accidental event or a systematic problem. The existing eight-wheel continuous evenness meter is difficult to track the trajectory after movement, and it is difficult to accurately recheck the data. Summary of the Invention

[0004] The purpose of the present invention is to provide a mobile platform for high-precision pavement evenness detection to solve the above technical problems.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions: A mobile platform for high-precision pavement evenness detection includes a support beam, an eight-wheel suspension, walking wheels, a traction link structure, a bracket, a measuring wheel, a sensor, a fixed seat, a trace water tank, and a follow-up pump water wheel. The front and rear parts of the bottom end of the support beam are respectively installed with eight-wheel suspensions. The walking wheels are distributed on the eight-wheel suspensions. The traction link structure is installed on the front eight-wheel suspension. The bracket is installed in the middle of the bottom end of the support beam. The measuring wheel is installed at the rear of the bracket. The sensor is installed at the front of the bottom end of the support beam, and the measuring wheel corresponds to the sensor through the bracket. The fixed seat is installed at the rear of the top end of the support beam. The trace water tank is installed on the fixed seat. The follow-up pump water wheel is installed at the rear of the bottom end of the support beam.

[0006] On the basis of the above technical solutions, the trace water tank includes a box body, a water injection interface, air holes, a water pipe, a peristaltic part, and pump water holes. The box body is installed on the rear part of the support beam through the fixed seat. The water injection interface is opened in the middle of the top end of the box body. The air holes are distributed on the top end of the box body. The top end of the water pipe is connected to the box body through the fixed seat. The peristaltic part is arranged at the lower part of the water pipe. The pump water holes are distributed at the lower part of the peristaltic part.

[0007] Based on the above technical solution, the follow-up pump water wheel includes a fixed block, a pump water cover, a shaft hole, a water pipe interface, a pipe groove, and a pump water wheel. The fixed block is fixed to the rear part of the bottom end of the support beam. The pump water cover is installed at the bottom end of the fixed block. The shaft hole is opened in the middle of the pump water cover. The water pipe interface is opened at the rear part of the pump water cover according to the measured moving direction. The pipe groove is opened in the middle inside the pump water cover, and the peristaltic part is fixed to the pipe groove through the water pipe interface. The pump water wheel is installed in the pump water cover through the shaft hole.

[0008] Based on the above technical solution, the pump water wheel includes a wheel body, a rotating shaft, a pump water groove, a peristaltic block, and water seepage lines. The rotating shaft is installed in the middle of the wheel body, and the wheel body is connected to the shaft hole through the rotating shaft. The pump water groove is circumferentially opened in the middle of the side end of the wheel body and corresponds to the pipe groove. The peristaltic blocks are distributed in the pump water groove, and the water seepage lines are distributed on the side end of the wheel body.

[0009] Based on the above technical solution, as the wheel body rotates, the peristaltic blocks peristaltically pump the water in the box body into the water seepage lines through the peristaltic part.

[0010] Compared with the prior art, the present invention has the following advantages: By installing a trace water tank and a follow-up pump water wheel on the eight-wheel continuous flatness meter, water stains are left on its trajectory when the eight-wheel continuous flatness meter moves for measurement, so that the original path can be found to obtain data when data recheck is required along the original path.

[0019] The trace water tank 9 includes a box body 11, a water injection interface 12, an air hole 13, a water pipe 14, a peristaltic part 15, and a water pump hole 16. The box body 11 is installed on the rear part of the support beam 1 through a fixed seat 8. The water injection interface 12 is opened in the middle of the top of the box body 11. The air hole 13 is distributed at the top of the box body 11. The top of the water pipe 14 is connected to the box body 11 through the fixed seat 8. The peristaltic part 15 is arranged at the lower part of the water pipe 14, and the water pump hole 16 is distributed at the lower part of the peristaltic part 15.

[0020] The follower pump water wheel 10 includes a fixed block 17, a pump water cover 18, an axial hole 19, a water pipe interface 20, a pipe groove 21, and a pump water wheel 22. The fixed block 17 is fixed to the rear of the bottom end of the support beam 1, the pump water cover 18 is installed at the bottom end of the fixed block 17, the axial hole 19 is opened in the middle of the pump water cover 18, the water pipe interface 20 is opened at the rear of the pump water cover 18 according to the measurement movement direction, the pipe groove 21 is opened in the middle of the pump water cover 18, and the peristaltic part 15 is fixed to the pipe groove 21 through the water pipe interface 20, and the pump water wheel 22 is installed on the pump water cover 18 through the axial hole 19.

[0021] The pump wheel 22 includes a wheel body 23, a rotating shaft 24, a pump water groove 25, a peristaltic block 26, and a water seepage pattern 27.

The peristaltic block 26 moves with the rotation of the wheel body 23, pressing the peristaltic part 15 of the water pipe 14. While the water in the peristaltic part 15 is twisted out through the water pump hole 1, the water in the box body 11 is sucked along the water pipe 14 for replenishment. (The water in the box body 11 can be added with pigment to leave clearer marks) to realize the rotation of the wheel body 23 to pump water circulation. The pumped water is distributed on the wheel surface of the wheel body 23 through the seepage lines 27. During the rolling process, the wheel body 23 leaves the water in the seepage lines 27 on the track to form water stains, so that the original path can be found to obtain data when the original path is needed for data review.
