Description

Technical Field

[0001] This utility model relates to a road rut detection device, belonging to the field of road detection technology. Background Technology

[0002] Rutting depth directly reflects the comfort of vehicle driving, as well as the safety and service life of the road surface. Rutting depth testing can provide important information for decision-makers, enabling them to make optimized decisions for road maintenance, repair, and resurfacing.

[0003] Existing detection methods generally employ automated detection equipment, which uses displacement sensors mounted on the vehicle body to quickly and continuously detect road cross-sections. The equipment mainly consists of three parts: a detection beam, sensors, and a computer system. When there are a sufficient number of sensors, it can detect the depth and shape of ruts on the road surface.

[0004] Based on practical experience, the following technical problems still exist with existing automatic road rut detection equipment:

[0005] The width of the detection area formed by multiple sensors on the detection beam is fixed, but the road width varies. The width of the detection area cannot be adaptively adjusted according to the road width. When the road width is greater than the width of the detection area, the vehicle body needs to move back and forth to achieve full detection, which is inefficient and can easily lead to inaccurate data.

[0006] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0007] This invention addresses the shortcomings of the prior art by providing a road rut detection device that allows the width of the detection area to be adaptively adjusted according to the road width, thus enabling automatic detection of ruts on roads of different widths.

[0008] To solve the above technical problems, the present invention adopts the following technical solution:

[0009] The road rut detection device includes a U-shaped frame, the open end of which is fixed to the front or rear end of the vehicle body, and a row of first sensors is installed on the end face of the frame away from the vehicle body.

[0010] A transversely arranged conveyor belt is installed inside the U-shaped cavity of the fixed frame. A movable seat is installed on the upper and lower sides of the conveyor belt. The movable seats move with the conveyor belt and are staggered. The inward sides of the two movable seats are connected to a horizontally arranged arm through flanges. A row of second sensors is installed below the end of the arm away from the movable seats.

[0011] Furthermore, both the first and second sensors are evenly distributed laterally.

[0012] Furthermore, the two ends of the conveyor belt are wound around the driving wheel and the driven wheel, and the axial direction of the driving wheel and the driven wheel is the same as the direction of travel of the vehicle body.

[0013] Furthermore, the driving wheel and the driven wheel are rotatably connected to the fixed frame, wherein the driving wheel is connected to the motor drive, the motor is fixed inside the fixed frame, and the motor is a forward and reverse reversing motor.

[0014] Furthermore, the arm has a hollow structure.

[0015] Furthermore, both the first and second sensors are non-contact displacement sensors, which are set vertically toward the road surface.

[0016] Furthermore, the conveyor belt is equipped with a linear guide rail, which is fixedly installed horizontally.

[0017] Furthermore, sliders are installed on the upper and lower sides of the linear guide rail, respectively, and the two sliders are staggered. The sliders are fixedly connected to the moving seat on the periphery of the conveyor belt by bolts.

[0018] Furthermore, the bolts are installed vertically through the surface of the conveyor belt.

[0019] Furthermore, limit blocks are installed at both ends of the linear slide rail along its length.

[0020] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0021] In this invention, the motor drives the conveyor belt to rotate, which in turn drives the moving seat and the arm to move stably along the linear slide rail. While the upper arm slides to the left, the lower arm slides to the right, thereby increasing the width of the detection area formed by the first and second sensors. The width of the detection area can be adjusted by rotating the motor in both directions, thus making it suitable for the automatic detection of ruts on roads of different widths.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0028] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0029] like Figures 1-4 As shown in the figure, the present invention provides a road rut detection device, including a U-shaped fixed frame 1, the open end of the fixed frame 1 is fixed to the front or rear end of the vehicle body, and a row of first sensors 6 are installed on the end face of the fixed frame 1 away from the vehicle body. The first sensors 6 are evenly distributed in the transverse direction.

[0030] A transversely arranged conveyor belt 4 is installed inside the U-shaped cavity of the fixed frame 1. The two ends of the conveyor belt 4 are wound around the driving wheel 2 and the driven wheel 3. The axis of the driving wheel 2 and the driven wheel 3 is in the same direction as the travel direction of the vehicle body.

[0031] The driving wheel 2 and the driven wheel 3 are rotatably connected to the fixed frame 1. The driving wheel 2 is connected to the motor 5 for transmission. The motor 5 is fixed inside the fixed frame 1. The motor 5 is a forward and reverse motor and provides power for the rotation of the conveyor belt 4.

[0032] A movable seat 7 is installed on the upper and lower sides of the conveyor belt 4 respectively. The movable seat 7 moves with the conveyor belt 4. The two movable seats 7 are staggered. The inner sides of the two movable seats 7 are connected to the horizontally arranged arm 8 through flanges 9.

[0033] A row of second sensors 10 is installed below the end of the arm 8 away from the movable seat 7, and the second sensors 10 are evenly distributed in the lateral direction.

[0034] The arm 8 has a hollow structure, which facilitates internal wiring.

[0035] Both the first sensor 6 and the second sensor 10 are non-contact displacement sensors, which are set vertically toward the road surface and detect the depth of ruts during movement.

[0036] The conveyor belt 4 is equipped with a linear slide rail 11, which is fixedly installed horizontally.

[0037] The linear guide rail 11 has sliders 12 installed on its upper and lower sides respectively, which are slidably connected to it. The two sliders 12 are staggered. The sliders 12 are fixedly connected to the movable seat 7 on the periphery of the conveyor belt 4 by bolts. The bolts are set to penetrate the surface of the conveyor belt 4 in a vertical direction.

[0038] The cooperation between slider 12 and linear guide rail 11 ensures the stability of moving seat 7 and arm 8 during movement.

[0039] Limiting blocks 13 are installed at both ends of the linear slide rail 11 along its length direction. The limiting blocks 13 limit the movement stroke of the slider 12 along the linear slide rail 11.

[0040] The specific working principle of this utility model is as follows:

[0041] The vehicle body pulls the entire testing device to the section of road to be tested, and then moves slowly on the section of road to be tested;

[0042] Motor 5 drives conveyor belt 4 to rotate, which in turn drives moving seat 7 and arm 8 to move stably along linear slide rail 11. While the upper arm 8 slides to the left, the lower arm 8 slides to the right, thereby increasing the width of the detection area formed by the first sensor 6 and the second sensor 10. The width of the detection area can be adjusted by the forward and reverse rotation of motor 5, thus making it suitable for detecting ruts on roads of different widths.
