Description

Technical Field

[0001] The invention relates to the technical field of road surface detection, in particular to a large-scale highway detection device. Background Art

[0002] Road inspection vehicles integrate and apply modern information technology, using motor vehicles as a platform to integrate optoelectronics, IT and 3S technologies. When the vehicle is in normal driving, it can automatically complete the data collection, analysis, classification and storage of road pavement images, road shape, three-dimensional images of road facilities, flatness and road geometric parameters. Existing road surface inspection equipment detects the flatness of the road surface by emitting multi-point collimated laser beams to the road surface, but the laser needs to be adjusted to cover the entire road surface at different road widths. The adjustment process cannot be carried out in real time and is inefficient. In addition, when the inspection vehicle passes through a curve or an inclined road surface, the relative position of the detection device and the road surface will change, which will affect the detection value.

[0003] Therefore, it is necessary to provide a large-scale highway detection device to solve the problems raised in the above background technology. Summary of the invention

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a large-scale highway detection equipment, including a vehicle body, a bracket fixed to the rear of the vehicle body, a balance frame connected to the bracket, a cross bar perpendicular to the direction of travel of the vehicle body connected to the balance frame, and two detection components symmetrically arranged on both sides of the cross bar.

[0005] Further, as a preference, the balancing frame is rotatably connected to the bracket, the rotation axis of which is perpendicular to the bottom surface of the vehicle body, and can be driven to rotate by a motor.

[0006] Further, as a preference, the crossbar is rotatably connected to the balance frame, the rotation axis of which is parallel to the traveling direction of the vehicle body, and can be driven to rotate by motor 2.

[0007] Furthermore, as a preference, a slide groove is provided in the cross bar, and each of the detection components is slidably connected to the slide groove via a slider.

[0008] Further, as a preference, a rack is slidably provided on the upper and lower sides of the slide groove, a gear is provided at the center of the cross bar, the upper and lower sides of the gear are respectively meshed with two racks, and each of the racks is fixed to a slider.

[0009] Furthermore, as a preference, an adjustment motor is also fixed in the cross bar, and an output shaft of the adjustment motor is connected to a gear.

[0010] Further, preferably, the detection component comprises a fixed plate, which is an arc-shaped plate fixedly connected to the slider, and a plurality of connecting rods are evenly distributed below the fixed plate, and a laser sensor is fixed to the other end of each connecting rod.

[0011] Further, as a preference, a central axis is fixed at the center of the fixing plate, a vertical laser sensor is fixed below the central axis, the connecting rods are distributed on both sides thereof, and the connecting rods are rotatably hinged to the fixing plate;

[0012] An arc-shaped sliding plate is slidably sleeved in the central axis, and a rotating sleeve is rotatably connected to the sliding plate corresponding to the position of each connecting rod. Each rotating sleeve is slidably sleeved on the periphery of the connecting rod in a one-to-one correspondence.

[0013] Further, as a preference, the central shaft and the sliding plate, and each rotating sleeve and the connecting rod are connected via sliding bushings.

[0014] Further, as a preference, two connecting rods are symmetrically hinged above the cross bar, and the other ends of the connecting rods are respectively hinged to the middle parts of the two sliding plates.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In the present invention, the laser sensors distributed in arcs on both sides of the crossbar can perform fan-shaped detection on the ground. By analyzing the distance change of each laser sensor, the road condition can be dynamically detected. By changing the distance between the sliding plate and the fixed plate, the angle between each adjacent connecting rod can be changed synchronously, thereby changing the range of its fan-shaped detection to adapt to roads of different widths.

[0017] In the present invention, when the slider slides to change the distance between the two detection components, the sliding plate is driven to slide through the action of the connecting rod, so that the angle between the laser sensors changes synchronously, thereby changing the range of its fan-shaped detection, and making the fan-shaped detection surfaces of the two detection components always fit together.

DETAILED DESCRIPTION

[0021] See also Figure 1 and Figure 2 In an embodiment of the present invention, a large-scale highway detection device includes a vehicle body 1, a bracket 2 is fixed to the rear of the vehicle body 1, a balance frame 3 is connected to the bracket 2, a cross bar 4 perpendicular to the travel direction of the vehicle body 1 is connected to the balance frame 3, and two detection components 6 are symmetrically provided on both sides of the cross bar 4.

[0022] In this embodiment, the balance frame 3 is rotatably connected to the bracket 2, and its rotation axis is perpendicular to the bottom surface of the vehicle body 1, and it can be driven to rotate by a motor 31.

[0023] In this embodiment, the cross bar 4 is rotatably connected to the balance frame 3 , the rotation axis of which is parallel to the moving direction of the vehicle body 1 , and can be driven to rotate by the second motor 32 .

[0024] In this embodiment, a slide groove 41 is formed in the cross bar 4 , and each of the detection components 6 is slidably connected to the slide groove 41 via a slider 5 .

[0025] In this embodiment, a rack 7 is slidably provided on the upper and lower sides of the slide slot 41, a gear 8 is provided at the center of the crossbar 4, the upper and lower sides of the gear 8 are respectively meshed with two racks 7, and each of the racks 7 is fixed to a slider 5. The meshing of the gear 8 and the rack 7 enables the detection components 6 on both sides to move synchronously, so that they always maintain symmetry.

[0026] In this embodiment, an adjustment motor 10 is also fixed in the crossbar 4, and the output shaft of the adjustment motor 10 is connected to the gear 8. That is to say, the adjustment motor 10 can drive the detection components 6 on both sides to adjust the distance to be suitable for roads of different widths.

[0027] In this embodiment, the detection assembly 6 includes a fixed plate 61, which is an arc-shaped plate fixedly connected to the slider 5, and a plurality of connecting rods 62 are evenly distributed below the fixed plate 61, and a laser sensor 63 is fixed to the other end of each of the connecting rods 62. The laser sensors 63 distributed in arcs on both sides of the crossbar 4 can perform fan-shaped detection on the ground, and the road condition of the road surface can be dynamically detected by analyzing the distance change of each laser sensor 63.

[0028] In this embodiment, a central shaft 64 is fixed at the center of the fixing plate 61, a vertical laser sensor 63 is fixed below the central shaft 64, the connecting rods 62 are distributed on both sides thereof, and the connecting rods 62 and the fixing plate 61 are rotatably hinged;

[0029] The central shaft 64 is slidably provided with an arc-shaped sliding plate 65, and the sliding plate 65 is rotatably connected with a rotating sleeve 66 corresponding to the position of each connecting rod 62, and each rotating sleeve 66 is slidably provided on the outer periphery of the connecting rod 62 in a one-to-one correspondence. In other words, by changing the distance between the sliding plate 65 and the fixed plate 61, the angle between each adjacent connecting rod 62 can be changed synchronously, thereby changing the range of the fan-shaped detection to adapt to roads of different widths.

[0030] In this embodiment, the central shaft 64 and the sliding plate 65, and each rotating sleeve 66 and the connecting rod 62 are connected by sliding bushings. The sliding bushings are made of polytetrafluoroethylene, which has lubricating properties, reduces vibration and friction between sliding parts, and improves detection accuracy.

[0031] In this embodiment, two connecting rods 9 are symmetrically hinged on the top of the crossbar 4, and the other ends of the connecting rods 9 are respectively hinged to the middle of the two sliding plates 65. That is to say, when the slider 5 slides to change the distance between the two detection components 6, the sliding plate 65 is driven to slide by the action of the connecting rod 9, so that the angle between the laser sensors 63 is changed synchronously, thereby changing the range of its fan-shaped detection, and making the fan-shaped detection surfaces of the two detection components 6 always fit together.

[0032] In specific implementation, the driving adjustment motor 10 adjusts the distance between the detection components 6 on both sides so that the laser sensor 63 closest to the outside of the detection component 6 is located at the edge of the road. Moreover, when the vehicle body 1 is moving, the motor 1 31 changes the horizontal rotation position of the cross bar 4 so that the two laser sensors 63 closest to the outside of the vehicle body 1 remain at the edge of the road when the vehicle body 1 passes through a curve. The motor 2 32 changes the vertical rotation position of the cross bar 4 so that the two laser sensors 63 closest to the outside of the vehicle body 1 remain at the same height as the road when the vehicle body 1 passes through an inclined road surface.

[0033] The vehicle body 1 can dynamically detect the road condition through the distance change of each laser sensor 63 while moving, that is, the position where the laser sensor 63 fluctuates greatly indicates poor road conditions, and the position where the distance of the laser sensor 63 changes suddenly may have cracks or depressions, so the road surface at that position can be inspected and repaired.

[0034] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
