Problems solved by technology

[0004] The detection of the above-mentioned patent is to directly install the level on the mobile car, and judge the inclination degree of the road according to the degree of inclination during the passing of the car. Only the slope of the road can be measured, and the unevenness of the road means that in a certain place Potholes appear, although the above patent can make the value of the level meter change to a certain extent after one end of the trolley enters the pothole, but these small value changes cannot effectively remind the inspectors to pay more attention to the land , causing potholes to be difficult to be found in time;
[0005] And the traditional detection device mostly draws marks on the ground after detecting the deviation of the road surface, and makes positioning to guide the repair personnel to repair. However, it takes more time to find the few drawn marks on the longer road. Concentrated attention and slower speed for observation and search, resulting in longer time for road inspection and repair, increasing the time for road acceptance

Embodiment 1

[0030] see figure 1 , image 3 and Figure 4, the present embodiment provides a road section smoothness detection device after asphalt paving in highway engineering, comprising a frame plate 1, the top middle of the frame plate 1 is fixedly connected with a level 3, which can detect the overall inclination angle of the road surface, so The bottoms of both ends of the frame plate 1 are fixedly connected with a mobile trolley 2, and the middle part of one side of the frame plate 1 is fixedly connected with a No. 1 support plate 4, and the middle part of the No. 1 support plate 4 is threadedly connected with a threaded rod 5. The bottom of the threaded rod 5 is plugged with a telescopic block 6, and the bottom of the telescopic block 6 is rotatably connected with a No. 2 rolling ball 15. The setting of the No. 2 rolling ball 15 is convenient to reduce the telescopic block 6 and the sticker when the threaded rod 5 rotates. Frictional force between the ground, the bottom of the t...

Embodiment 2

[0033] see Figure 1-3 , further improvements have been made on the basis of Example 1:

[0034] The top of the floor 12 and the side of the No. 2 insertion rod 22 are fixedly connected with a No. 2 support plate 16, and the side of the No. 2 support plate 16 close to the No. 2 insertion rod 22 is movably connected with two connecting plates 20 A switch 21 is relatively fixedly connected to the sides of the two connecting plates 20 close to each other, and a switch 23 is fixedly connected to the top of the No. 2 insertion rod 22 and between the two switches 21. The No. 2 insertion rod The top of 22 is provided with a No. 3 spring 24, and the two ends of the No. 3 spring 24 are fixedly connected with the dial 23 and the floor 12 respectively. When moving to a relatively narrow depression or protruding road surface, the floor 12 cannot be accurately detected. When the second insertion rod 22 is inserted into the depression or raised due to the protrusion, the flatness of the ro...

Embodiment 3

[0037] see figure 1 and Figure 5-7 , further improvements have been made on the basis of Example 1:

[0038] The side of the shelf board 1 away from the floor 12 is provided with a standard warehouse 26, and the interior of the standard warehouse 26 is provided with a number of marks 27. By replacing the traditional marking coordinates with physical marks, it is convenient for later maintenance personnel to find. , the mark 27 includes a tumbler 32, the top of the tumbler 32 is fixedly connected with a connecting rod 33, and one side of the top of the connecting rod 33 is fixedly connected with a flag 34, and the physical mark 27 stands on the ground under the support of the tumbler 32. On the road, it is convenient for later maintenance personnel to observe and search, and improve the maintenance efficiency. The standard warehouse 26 is installed at an angle of more than 30 degrees, and the outer wall of one side of the standard warehouse 26 is fixedly connected with a moto...

Abstract

The invention discloses a road section flatness detection device after asphalt paving in highway engineering, which comprises a frame plate, a gradienter is fixedly connected to the middle of the top end of the frame plate, moving trolleys are fixedly connected to the bottoms of the two ends of the frame plate, a first support plate is fixedly connected to the middle of one side of the frame plate, and a threaded rod is in threaded connection to the middle of the first support plate; a telescopic block is inserted into the bottom of the threaded rod, a second insertion rod which stretches out and draws back through a spring is arranged on the floor, when the second insertion rod moves to a narrow pit and a protrusion, the second insertion rod stretches out and draws back on the floor, concave and convex parts at tiny positions can be monitored, the equipment monitoring capacity is improved, and the problem that traditional equipment is not comprehensive in monitoring is solved; when an obvious concave or convex road surface exists, the second inserting rod ascends and descends obviously, the shifting plate on the top makes contact with the switch, the motor on the side wall of the mark bin is started, the purpose of releasing the marks is achieved, later repairing personnel can find the marks conveniently, and the repairing efficiency is improved.

Description

Technical field: [0001] The invention belongs to the technical field of road detection equipment, and in particular relates to a detection device for road section smoothness after asphalt paving in highway engineering. Background technique: [0002] my country is a country with a large infrastructure. In order to facilitate people's travel, various expressways, viaducts, expressways and other roads intersect each other. Road construction has become a major feature of our country's construction. Among them, expressways are for long-distance travel and avoid congested roads. The running vehicle can reach more than 100 kilometers per hour. During the high-speed driving of the vehicle, if it encounters potholes and protrusions, it will easily cause the wheels to turn, etc., which will easily cause traffic accidents. [0003] In the prior art, the Chinese patent with the patent number CN201921354797.X is based on the road level detection device for civil engineering construction, ...
