Technical Field
[0001] The utility model relates to the technical field of road and bridge engineering, in particular to a flatness detection device for road and bridge engineering construction. Background Technique
[0002] The flatness of road and bridge engineering is one of the important indicators of pavement construction quality and service level. An uneven road surface will increase the driving resistance and cause additional vibration of the vehicle. This vibration will cause driving bumps, affecting the driving speed and safety, the smoothness of driving and the comfort of passengers. At the same time, the vibration will also exert an impact force on the road surface, thus aggravating the damage of the road surface and the vehicle as well as the wear of the tires. An uneven road surface will accumulate rainwater and accelerate the damage of the road surface. Therefore, the detection and evaluation of flatness is a very important link in highway construction and maintenance. Generally, the flatness detection instruments for road and bridge engineering are divided into two categories: section type and response type. The section type instruments measure the unevenness of the road surface, such as the commonly used 3m straightedge and continuous flatness meter. The response type instruments measure the bumpy situation of the vehicle vibration caused by the unevenness of the road surface.
[0003] However, the detection surface of the existing flatness detection device for road and bridge engineering construction is limited, and multiple detections are required. The detection process is cumbersome, and it is not convenient to adjust the size of the detection surface, which is not convenient for the staff to use.

[0022] Such as Figures 1 - 4As shown in the figure, a flatness detection device for road and bridge engineering construction includes a flatness detection device main body 1. On one side of the bottom of the flatness detection device main body 1, a detection component 2 is provided. The detection component 2 includes a movable block 3. When detecting the flatness of the road surface, the roller 9 rolls on the detected road surface. The rolling roller 9 supports and pushes the second fixed rod 8 following the unevenness of the road surface, driving the push rod 10 to push at one end of the detection head 7. Thus, the spring provided in the detection head 7 pushes one end of the detection head 7 to change following the change of the road surface. According to the telescopic change of one end of the detection head 7, the flatness of the road surface is recorded. The flatness of the current road surface is simultaneously recorded by three identical detection components 2 provided on one side of the bottom of the flatness detection device main body 1. Multiple identical detection components 2 increase the detection area, the one-way detection area is larger, saving detection time, and the detection results are more reliable through the comparison of multiple groups of data.
[0023] As Figure 2 and Figure 3 shown in the figure, a support component 11 is provided on one side of the bottom of the flatness detection device main body 1.

The operation freedom is higher, which is convenient for the staff to use.
[0025] Working principle
[0026] It should be noted that the present utility model is a flatness detection device for road and bridge engineering construction. When in use, first pull the main body 1 of the flatness detection device and install the main body 1 of the flatness detection device on a towing vehicle. At this time, the roller 9 supports on the road and bridge where flatness detection is required. The roller 9 pushes the second fixing rod 8 to push the push rod 10, and the push rod 10 pushes one end of the detection head 7 to compress the spring arranged inside the detection head 7. The second fixing rod 8 slides outside the connecting rod 6. At the same time, the detection head 7 is supported at the bottom of the main body 1 of the flatness detection device by the first fixing rod 5 and the movable block 3. The fastening set screw 15 fixes the adjusting block 14 to support the support plate 12 on the main body 1 of the flatness detection device through the first fastening bolt 13, and the support plate 12 supports the first fixing rod 5. Then, the towing vehicle drives the main body 1 of the flatness detection device to move at a constant speed. The main body 1 of the flatness detection device drives the slider 4 to drive the movable block 3, the movable block 3 drives the first fixing rod 5 to drive the connecting rod 6, the connecting rod 6 drives the detection head 7 to drive the second fixing rod 8, and the second fixing rod 8 drives the roller 9 to roll on the detection road surface. When the detection road surface is uneven and the roller 9 rolls on the road surface, the roller 9 pushes the second fixing rod 8 to drive the push rod 10 to push one end of the detection head 7. Thus, the spring arranged inside the detection head 7 pushes one end of the detection head 7 to change following the road surface. According to the telescopic change of one end of the detection head 7, the road surface flatness is recorded. The flatness of the current road surface is simultaneously recorded by three groups of identical detection components 2 arranged on one side of the bottom of the main body 1 of the flatness detection device, achieving the purpose of increasing the detection area through multi-group cooperation.
[0027] By turning the first fastening bolt 13, the first fastening bolt 13 disengages from the support plate 12, and the support plate 12 disengages from the adjusting block 14. Then, pull the second fixing rod 8 to drive the connecting rod 6 to drive the first fixing rod 5 to rotate on the articulated movable block 3. After rotating the second fixing rod 8, it is received at the bottom of the flatness detection device main body 1. Turn the connecting screw rod 16. One end of the connecting screw rod 16 is threadedly connected to the internal thread of the threaded hole opened on the second fixing rod 8. The adjusting block 14 drives the connecting screw rod 16 to be installed on the second fixing rod 8, and the connecting screw rod 16 fixes the second fixing rod 8 at the bottom of the flatness detection device main body 1, which is convenient for the towing vehicle to move the flatness detection device main body 1. By turning the fastening set screw 15, the fastening set screw 15 disengages from the limit hole opened on the current flatness detection device main body 1. Turn the second fastening bolt 18, and the second fastening bolt 18 no longer abuts against the bottom of the flatness detection device main body 1. Push the second fixing rod 8 to drive the connecting rod 6 to drive the first fixing rod 5. The first fixing rod 5 drives the movable block 3 to drive the slider 4 to slide in the chute opened on the flatness detection device main body 1. At the same time, the second fixing rod 8 drives the connecting screw rod 16 to drive the adjusting block 14 to slide on one side of the top of the flatness detection device main body 1. According to the limit groove opened on the flatness detection device main body 1, adjust the spacing and position of the three groups of identical detection components 2 provided on the flatness detection device main body 1, so as to adjust the road surface detection width of the three groups of detection components 2, or the road surface width of a single group can be detected, achieving the purpose of conveniently adjusting the detection width.
