Description

Technical Field

[0001] This utility model belongs to the field of road smoothness detection technology, and relates to a smoothness detection device for road engineering construction. Background Technology

[0002] Road engineering refers to the planning, design, construction, and maintenance of roads.

[0003] Like any other type of civil engineering, road engineering has distinct technical, economic, and managerial characteristics throughout the entire process of maintenance and management. Road smoothness is a key indicator for evaluating road performance, reflecting the comfort and quality of driving on the road surface. It is of great significance in evaluating road service performance. Road smoothness testing requires a road engineering construction smoothness testing device.

[0004] For example, the road surface smoothness testing device disclosed in patent publication number CN215003477U, published on December 3, 2021, although it can be equipped with multiple sets of infrared ranging sensors as needed, and the sliding plate is slid upwards, the slider is slid from the end of the slide groove into the slide groove, the distance between each infrared ranging sensor is adjusted, and after adjusting to a suitable distance, the fixed insertion hole on the slider overlaps with the through hole at a suitable position, and the corresponding telescopic hydraulic rod is activated to insert the pin into the through hole and the fixed insertion hole to fix the infrared ranging sensor under the slider, so as to make the measurement range larger and the measurement more accurate; however, it does not have the function of simultaneously cleaning the road surface during use. There may be gravel, branches and other impurities on the road surface, which will cause unevenness of the road surface during the test, reducing the accuracy of the test. Therefore, it is urgent to redesign a road surface smoothness testing device to solve the problem of inaccurate error in the test of road surface smoothness.

[0005] The present invention aims to solve the technical problems existing in the prior art. To this end, a road engineering construction flatness detection device is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a road surface smoothness testing device for road construction, which solves the problem of uneven road surface and errors in the accuracy of road surface smoothness testing in the existing technology.

[0007] The technical solution adopted by this utility model is a road engineering construction flatness detection device, including a mobile vehicle, the mobile vehicle including a top crossbeam, and a first support arm and a second support arm fixedly connected to both sides of the top crossbeam respectively.

[0008] A level is fixedly connected to the top of the top beam, a mounting bracket is fixedly connected to the bottom of the first support arm on one side, and a mounting bracket is fixedly connected to the bottom of the second support arm on the other side. The mounting bracket is equipped with a cleaning component.

[0009] The first support arm and the second support arm have guide grooves perpendicular to the direction of the mounting frame on their opposite sides.

[0010] The top crossbeam has an internal cavity, and the cavity contains detection and alarm components.

[0011] The features of this utility model also include:

[0012] The cleaning assembly includes a pair of servo motors, each fixedly connected to a mounting bracket. The output end of the servo motor is fixedly connected to a rotating shaft, and the other end of the rotating shaft is fixedly connected to a cleaning brush.

[0013] The pivot shaft passes through the mounting bracket and is slidably connected to the mounting bracket.

[0014] The detection assembly includes a lifting plate, with limit sliders fixedly connected to both sides of the lifting plate. The limit sliders abut against the guide groove. A detection block is fixedly connected to the side of the lifting plate away from the cleaning brush, and the detection block passes through the mounting frame.

[0015] A detection tip is fixedly connected to the bottom of the detection block.

[0016] A set of springs is fixedly connected to the side of the lifting platform away from the mounting frame, and the other end of the springs is fixedly connected to the bottom of the top crossbeam.

[0017] A pair of connecting rods are fixedly connected to the side of the lifting plate away from the mounting frame. An extrusion plate is fixedly connected to the other end of the connecting rods. The extrusion plate is located inside the cavity and abuts against the inner wall of the cavity. The connecting rods pass through the top crossbeam.

[0018] The alarm assembly includes an alarm, with a point control switch one fixedly connected to one side and a point control switch two fixedly connected to the other side. Point control switch one abuts against the lifting plate, and point control switch two abuts against the pressing plate. The alarm is fixedly connected to the top crossbeam.

[0019] The beneficial effects of this utility model are:

[0020] 1. When this device is in use, the moving vehicle moves the detection block. When there are uneven areas on the road surface, the uneven block squeezes the detection block and the lifting plate to rise, or the detection block and the lifting plate are lowered by the action of the spring. That is, when the road surface is uneven, the detection block and the lifting plate move vertically. When the lifting plate rises, it squeezes the first control switch, which controls the alarm to sound an alarm to remind the staff. When the lifting plate falls, it drives the squeezing plate to fall through the level, and the squeezing plate squeezes the second control switch, which also controls the alarm to sound an alarm to remind the staff. This makes it easy to locate the uneven road surface.

[0021] 2. The device is equipped with a servo motor, which controls the rotation of the shaft. The shaft drives the cleaning brush to sweep the road surface, avoiding the influence of debris such as gravel and branches on the road surface on the test results. The device can easily locate uneven road surfaces and avoid the influence of debris such as gravel and branches on the road surface on the test results. Attached Figure Description

[0026] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0027] like Figure 1 As shown, the road construction flatness testing device includes a mobile vehicle 1, which includes a top crossbeam 2, and a first support arm 3 and a second support arm 4 are fixedly connected to both sides of the top crossbeam 2.

[0028] A level 6 is fixedly connected to the top of the top beam 2, a mounting bracket 5 is fixedly connected to the bottom of the first support arm 3 on one side, and a mounting bracket 5 is fixedly connected to the bottom of the second support arm 4 on the other side. The mounting bracket 5 is equipped with a cleaning component.

[0029] like Figure 2 As shown, the first support arm 3 and the second support arm 4 are respectively provided with guide grooves 9 perpendicular to the direction of the mounting frame 5 on their opposite sides;

[0030] The top crossbeam 2 has a cavity 8 inside, and the cavity 8 is equipped with a detection component and an alarm component.

[0031] like Figure 2As shown, the cleaning assembly includes a pair of servo motors 10, which are fixedly connected to the mounting bracket 5. The output end of the servo motor 10 is fixedly connected to a rotating shaft 11, and the other end of the rotating shaft 11 is fixedly connected to a cleaning brush 12. The servo motor 10 controls the rotating shaft 11 to rotate, and the rotating shaft 11 drives the cleaning brush 12 to rotate to clean the road surface, so as to avoid the gravel and branches on the road surface from affecting the test results. The cleaning brush 12 is used for road cleaning.

[0032] The rotating shaft 11 passes through the mounting bracket 5 and is slidably connected to the mounting bracket 5.

[0033] like Figure 3 As shown, the detection assembly includes a lifting plate 17. Limiting sliders 13 are fixedly connected to both sides of the lifting plate 17. The limiting sliders 13 abut against the guide groove 9. A detection block 18 is fixedly connected to the side of the lifting plate 17 away from the cleaning brush 12. The detection block 18 passes through the mounting frame 5. A detection tip 19 is fixedly connected to the bottom of the detection block 18. A set of springs 20 is fixedly connected to the side of the lifting plate 17 away from the mounting frame 5. The other end of the springs 20 is fixedly connected to the bottom of the top crossbeam 2. The detection block 18 is used for road flatness detection. During the movement of the moving vehicle 1, the detection block 18 is moved. When there are uneven areas on the road surface, the uneven blocks squeeze the detection block 18 and the lifting plate 17 to rise, or the detection block 18 and the lifting plate 17 are lowered by the action of the springs 20. That is, when the road surface is uneven, the detection block 18 and the lifting plate 17 move vertically.

[0034] A pair of connecting rods 21 are fixedly connected to the side of the lifting plate 17 away from the mounting frame 5. The other end of the connecting rod 21 is fixedly connected to the extrusion plate 7. The extrusion plate 7 is located in the cavity 8 and abuts against the inner wall of the cavity 8. The connecting rod 21 passes through the top crossbeam 2.

[0035] like Figure 2 As shown, the alarm assembly includes an alarm 15. One side of the alarm 15 is fixedly connected to a point control switch 14, and the other side is fixedly connected to a point control switch 16. Point control switch 14 abuts against the lifting plate 17, and point control switch 16 abuts against the pressing plate 7. The alarm 15 is fixedly connected to the top crossbeam 2. When the lifting plate 17 rises, it presses the point control switch 14, which controls the alarm 15 to sound an alarm to alert the staff. When the lifting plate 17 falls, it drives the pressing plate 7 to fall via the level 6, which presses the point control switch 16. Point control switch 16 also controls the alarm 15 to sound an alarm to alert the staff, thus making it easy to locate uneven road surfaces.

[0036] The working principle of this utility model is as follows:

[0037] When the device is in use, the mobile vehicle 1 moves, driving the detection block 18 to move. When there are uneven areas on the road surface, the uneven block squeezes the detection block 18 and the lifting plate 17 to rise, or the detection block 18 and the lifting plate 17 are lowered by the action of the spring 20. That is, when the road surface is uneven, the detection block 18 and the lifting plate 17 move vertically. When the lifting plate 17 rises, it squeezes the point control switch 14, which controls the alarm 15 to sound an alarm to remind the staff. When the lifting plate 17 falls, it drives the squeezing plate 7 to fall through the connecting rod 21. The squeezing plate 7 squeezes the point control switch 26, which also controls the alarm 15 to sound an alarm to remind the staff. This makes it easy to locate the uneven road surface. At the same time, the device is equipped with a servo motor 10, which controls the rotating shaft 11 to rotate. The rotating shaft 11 drives the cleaning brush 12 to rotate and clean the road surface.
