Description

Technical Field

[0001] This utility model relates to the field of road surface testing technology, and in particular to an eight-wheeled road surface smoothness tester. Background Technology

[0002] Road surface smoothness is a key indicator for evaluating road quality and driving comfort, and its testing typically relies on various smoothness testing equipment. The eight-wheel smoothness meter, as a classic device, reflects longitudinal profile elevation changes by detecting the undulations of the wheels on the road surface. It boasts advantages such as accurate measurement and high stability, and is widely used in the testing of high-grade highways.

[0003] However, in actual use, when the detection wheel rolls on the road surface, it is very easy for asphalt, mud and other adhering substances to stick to it. These adhering substances will cause uneven mass distribution of the detection wheel and generate periodic rotational imbalance. This imbalance will introduce significant periodic noise, seriously interfere with the acquisition of real road surface contour data, and reduce the accuracy and reliability of the detection results. Utility Model Content

[0004] To overcome the shortcomings of the testing wheel easily adhering to asphalt, mud and other adhesives when rolling on the road surface, which leads to uneven mass distribution of the testing wheel and periodic rotational imbalance, this utility model provides an eight-wheel smoothness tester for road surface testing.

[0005] The technical solution is as follows: An eight-wheeled road surface evenness tester includes an eight-wheeled frame and a test wheel; the test wheel is connected to the middle of the eight-wheeled frame; a power supply module, an adjustment module for controlling and adjusting the position of the test wheel, and an information processing module for recording the lifting and lowering of the test wheel are connected to the eight-wheeled frame; it also includes an electric push rod, a mounting plate, a scraper, and an alarm light; the electric push rod is fixedly connected to the eight-wheeled frame; the extension end of the electric push rod is fixedly connected to the mounting plate; the scraper is fixedly connected to the mounting plate, and the scraper is located directly above the test wheel; the alarm light is fixedly connected to the eight-wheeled frame.

[0006] As a preferred option, the alarm light integrates an audible alarm module.

[0007] Preferably, the lower side of the scraper is curved.

[0008] Preferably, the scraper material is made of polyurethane, which is wear-resistant and does not damage the tire.

[0009] Preferably, a pressure sensor is also included; a pressure sensor is installed between the telescopic end of the electric actuator and the mounting plate.

[0010] Preferably, it also includes an electric heating frame; the electric heating frame is fixedly attached to the mounting plate; and the scraper is located inside the electric heating frame.

[0012] Preferably, the paint in the storage tank of the electric sprayer is a water-based reversible marking paint.

[0013] The beneficial effects are as follows: the information processing module intelligently diagnoses imbalances in the detection wheel caused by adhesive residue and triggers an alarm light; an electric push rod drives a mounting plate with a pressure sensor and a scraper to achieve constant pressure cleaning, minimizing wear on the detection wheel while ensuring effective cleaning; the added heating frame effectively prevents secondary adhesion of high-temperature asphalt to the scraper, improving operational capabilities under harsh conditions; and the electric sprayer can instantly apply biodegradable markings at fault points, providing a basis for accurate positioning and continuous testing. The entire system effectively solves the problems of traditional equipment requiring interruptions due to adhesive residue interference, poor cleaning results, and inaccurate re-measurement positioning, significantly improving the automation, data accuracy, and overall efficiency of road surface smoothness testing.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] Example: An eight-wheeled road surface evenness tester, such as... Figures 1-3 As shown, it includes an eight-wheeled frame 1 and a detection wheel 2; the detection wheel 2 is connected to the middle of the eight-wheeled frame 1; a power supply module, an adjustment module for controlling and adjusting the position of the detection wheel 2, and an information processing module for recording the raising and lowering of the detection wheel 2 are connected to the eight-wheeled frame 1; It also includes an electric push rod 3, a mounting plate 4, a scraper 5, and an alarm light 11; the electric push rod 3 is fixedly connected to the eight-wheel frame 1; the extension end of the electric push rod 3 is fixedly connected to the mounting plate 4; the scraper 5 is fixedly connected to the lower side of the mounting plate 4, and the scraper 5 is located directly above the detection wheel 2; the alarm light 11 is fixedly connected to the left side of the eight-wheel frame 1.

[0018] To enhance the warning effect, the alarm light 11 integrates an audible alarm module.

[0019] In order to conform to the contour of the outer ring surface of the detection wheel 2 and improve the effect of scraping off the adhering material, the lower side of the scraper 5 is set to be arc-shaped.

[0020] To improve service life, scraper 5 is made of wear-resistant polyurethane that does not damage the tire.

[0021] It also includes a pressure sensor 6; a pressure sensor 6 is installed between the telescopic end of the electric push rod 3 and the mounting plate 4.

[0022] It also includes an electric heating frame 7; the electric heating frame 7 is fixedly connected to the lower side of the mounting plate 4; and the scraper 5 is located inside the electric heating frame 7.

[0023] It also includes an electric sprayer 8, a mounting frame 9, and a spray pipe 10; the electric sprayer 8 is fixedly connected to the eight-wheeled frame 1, and the electric sprayer 8 is equipped with a storage box for storing paint; the mounting frame 9 is welded to the eight-wheeled frame 1; the spray pipe 10 is fixedly connected to the mounting frame 9, and the spray pipe 10 is located to the right of the inspection wheel 2; the discharge pipe of the electric sprayer 8 is connected to the spray pipe 10 through a flexible hose.

[0024] The paint in the storage tank of the electric sprayer is a water-based reversible road marking paint. Its characteristics are moderate adhesion. Under the action of vehicle rolling, rain washing and natural weathering, it can quickly decompose, peel off and dissipate within a few days, leaving no permanent residue on the road surface and is harmless to the environment.

[0025] by Figure 1 Based on the viewing angle, the side where the eight-wheeled frame number 1 is located is the front side.

[0026] In use, connect the left side of the eight-wheeled vehicle frame 1 to the external traction device. First, adjust the detection wheel 2 to contact the road surface to be tested. Then, manually start the external traction device to move the eight-wheeled vehicle frame 1 to the left on the road surface. The detection wheel 2 rolls on the road surface, detecting the true contour of the road surface. The information processing module inside the eight-wheeled vehicle frame 1 automatically records the detection data. The information processing module analyzes the real-time vibration data. When the information processing module detects the occurrence of periodic noise caused by the imbalance of the detection wheel 2 (due to adhering materials), it controls the alarm light 11 to flash. To improve the warning effect, the alarm light 11 integrates an audible alarm. The alarm module activates when staff receive an alarm, shutting down the external traction device. They then control the electric push rod 3 to move the mounting plate 4 and scraper 5 downwards, bringing the scraper 5 into contact with the detection wheel 2. The external traction device is then activated again, moving the eight-wheeled vehicle frame 1 to the left on the test surface, allowing the detection wheel 2 to roll across the scraper 5, which removes the adhesive residue. After removal, the electric push rod 3 moves the mounting plate 4 and scraper 5 upwards to reset them. The external traction device then moves the eight-wheeled vehicle frame 1 to the right on the test surface, moving the detection wheel 2 to a position where periodic noise is no longer present, allowing the testing to continue.

[0027] A pressure sensor 6 is installed between the telescopic end of the electric push rod 3 and the mounting plate 4, which can provide real-time feedback on the contact pressure between the scraper 5 and the detection wheel 2. No matter how worn or vibrating the detection wheel 2 is, the system can automatically adjust to maintain a constant and optimal contact pressure, which can ensure the cleaning effect and minimize the wear of the detection wheel 2.

[0028] When inspecting newly paved asphalt pavement in high temperatures, the soft asphalt easily sticks to the inspection wheel 2. After the scraper 5 removes the asphalt, it cools and hardens, sticking back to the scraper 5, causing secondary pollution and affecting subsequent cleaning. Therefore, manual cleaning of the scraper 5 is required, but the stickiness of the asphalt makes cleaning difficult. At this time, the power supply module on the eight-wheel frame 1 can supply power to the heating frame 7. The heating frame 7 heats the scraper 5, thereby raising the temperature of the adhered asphalt, reducing its viscosity, and making it easier to remove the asphalt.

[0029] After scraping is completed, in order to allow the detection wheel 2 to move precisely to the right to a position where no periodic noise occurs, an electric sprayer 8 is fixed to the eight-wheeled frame 1. Paint is pre-filled into the storage tank of the electric sprayer 8. When the information processing module detects that periodic noise caused by the imbalance of the detection wheel 2 (due to adhering material) begins to appear, the electric sprayer 8 is immediately started. The electric sprayer 8 sprays the paint in the storage tank onto the ground, forming a mark on the ground. Then, the detection wheel 2 is precisely moved to the right of the mark to continue the detection. It should be noted that the mark will quickly dissipate with rain or natural forces after the detection is completed.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
