Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and the features of different embodiments or examples without contradiction.

[0027] The following combination Figures 1-4 The embodiments of the present invention are described.

[0028] Figure 1 The schematic diagram of the structure of the first viewing angle of the measuring device provided by the embodiment of the present utility model is illustrated. Figure 2 The schematic diagram of the structure of the second viewing angle of the measuring device provided by the embodiment of the utility model is illustrated. Figure 1 and Figure 2A measuring device provided by an embodiment of the present invention includes a measuring wheel assembly 100 and a cleaning assembly 200. The measuring wheel assembly 100 includes a measuring wheel 120, which is used to move along a track on the object to be measured. The measuring wheel 120 is provided with a measuring device 130, which is used to measure the number of rotations of the measuring wheel 120; the cleaning assembly 200 is provided in front of the moving direction of the measuring wheel 120, and is used to clean foreign objects on the track.

[0029] In the above structure, by positioning cleaning assembly 200 ahead of the measuring wheel 120 in its direction of motion, cleaning assembly 200 can preemptively remove foreign matter, such as stones and dust, from the measuring wheel 120's path. This reduces the risk of bumps and deviations during the rolling process, thereby ensuring accurate measurement results. Furthermore, by promptly removing impurities from the road, wear and damage to the measuring wheel 120 caused by direct contact with hard objects is avoided, thereby extending the measuring wheel 120's service life.

[0030] In some possible embodiments, a data recording module can be installed within the measuring device 130 to record measurement data (including road conditions before and after cleaning, the number of revolutions of the measuring wheel 120, etc.) in real time and wirelessly transmit the data to a computer or cloud server for subsequent data analysis and processing. In other possible embodiments, a marker can be placed on the measuring wheel 120 to visually detect the number of revolutions and thereby calculate the distance traveled.

[0031] Reference Figure 1 In some embodiments of the present invention, the measuring wheel assembly 100 further includes a frame component 110 , and at least two measuring wheels 120 are provided, and the measuring wheels 120 are symmetrically arranged at both ends of the bottom of the frame component 110 .

[0032] In the above structure, by increasing the number of measuring wheels 120 and arranging them symmetrically, the stability of the measuring device during driving can be significantly improved. Even when encountering uneven roads or large obstacles, multiple measuring wheels 120 can better disperse the impact force, reduce bumps and deviations. Since the measuring device is more stable, the measuring wheels 120 are less subject to external interference during rolling, so the number of rotations can be recorded more accurately, thereby calculating a more accurate road length. This is especially important for road projects that require high-precision measurements. Secondly, the dual-wheel or multi-wheel design allows the measuring device to more easily cope with various road conditions, including narrow, rugged or complex terrain. This design enhances the versatility and adaptability of the measuring device, enabling it to function in a wider range of scenarios.

[0033] Specifically, the frame assembly 110 is the main structure of the entire measuring device, supporting the measuring wheel 120 and other auxiliary components. The frame assembly 110 can be made of a sturdy metal material (such as aluminum alloy or stainless steel) to ensure sufficient strength and durability. The frame can be rectangular or trapezoidal to facilitate the installation of the measuring wheel 120 and other components while maintaining overall stability. Specialized mounting brackets or supports are designed at both ends of the bottom of the frame assembly 110 to secure the measuring wheel 120. These mounting brackets should be adjustable to adjust the position and angle of the measuring wheel 120 as needed. Bearings or bushings may be included within the mounting brackets to reduce friction and wear on the measuring wheel 120 during rotation.

[0034] Reference Figure 1 In some embodiments of the present invention, the cleaning assembly 200 includes a suspension beam 210, a cleaning component 220 and a first transmission component 230. One end of the suspension beam 210 is connected to the frame component 110; the cleaning component 220 is arranged at the end of the suspension beam 210 away from the frame component 110; the first transmission component 230 is arranged between the measuring wheel 120 and the cleaning component 220, and the first transmission component 230 is used to transmit the rotational force of the measuring wheel 120 to the cleaning component 220, so that the cleaning component 220 cleans foreign matter.

[0035] It should be noted that the suspension beam 210 is an elongated structure, specifically a rectangular parallelepiped structure, and can be arranged horizontally. One end of the suspension beam 210 is welded to the frame member 110, or it can be detachably connected via bolts. The cleaning component 220 can be welded or detachably attached to the other end of the suspension beam 210 via bolts. In some possible embodiments, a lifting mechanism can be provided between the cleaning component 220 and the suspension beam 210 to adjust the height of the cleaning component 220, thereby enabling the distance between the cleaning component 220 and the road surface to be adjusted according to road conditions, thereby better cleaning the road surface.

[0036] Reference Figure 1 In some embodiments of the present invention, the first transmission component 230 includes a first transmission wheel 231, a transmission belt 232, and a second transmission wheel 233. The first transmission wheel 231 is located at the center of the measuring wheel 120 and is configured to rotate synchronously with the center of the measuring wheel 120. The second transmission wheel 233 is located at one end of the input shaft of the cleaning component 220. The transmission belt 232 is located between the first transmission wheel 231 and the second transmission wheel 233.

[0037] Specifically, a cylindrical protrusion extends from the outer side of the measuring wheel 120, and the first transmission wheel 231 is embedded in this protrusion. When the measuring wheel 120 rotates, it drives the protrusion to rotate. It should be noted that the protrusion does not change in height and rotates continuously around the center of the measuring wheel 120. The rotation of the measuring wheel 120 drives the rotation of the first transmission wheel 231, which, through the transmission of the transmission belt 232, drives the rotation of the second transmission wheel 233. The rotation of the second transmission wheel 233 serves as a power source for the cleaning component 220, thereby driving the cleaning component 220 to clean. In some possible embodiments, a tensioning pulley can be added to the transmission belt 232 to increase transmission efficiency.

[0038] Figure 3 The cross-sectional view of the cleaning component of the measuring device provided by the embodiment of the present utility model is illustrated. Figure 3 In some embodiments of the present invention, the cleaning component 220 includes a box body 221 and a cleaning head 224. The box body 221 is fixed to the suspension beam 210. A second transmission component is provided inside the box body 221, and the second transmission component is provided with an output shaft; the second transmission component is connected to the input shaft, and the second transmission component is used to transmit the force of the input shaft to the output shaft; the cleaning head 224 is provided at one end of the output shaft.

[0039] In the above structure, the power of the second transmission wheel 233 is transmitted to the cleaning head 224 through the second transmission component, and then the road surface is cleaned by the cleaning head 224.

[0040] Reference Figure 3 In some embodiments of the present invention, the second transmission component includes a first bevel tooth 222 and a second bevel tooth 223 that mesh with each other; the input shaft passes through the side wall of the box body 221 and is rotatably connected to the side wall, and the first bevel tooth 222 is provided at the end of the input shaft away from the second transmission wheel 233; the output shaft passes through the bottom wall of the box body 221 and is rotatably connected to the bottom wall, and the second bevel tooth 223 is provided at the end of the output shaft away from the cleaning head 224.

[0041] Specifically, the rotation of the second transmission wheel 233 drives the input shaft, which in turn drives the first bevel gear 222. The meshing transmission between the first and second bevel gears 222 and 223 drives the second bevel gear 223 to rotate. The second bevel gear 223 drives the output shaft, which in turn drives the cleaning head 224. The rotation of the cleaning head 224 clears foreign matter from the road surface. The cleaning head 224 can be equipped with a variety of types, such as a soft brush, a hard scraper, or a vacuum cleaner, to accommodate different types of impurities and road materials. Furthermore, the cleaning head 224 can be designed to be replaceable, making it easier for staff to select and replace it according to actual needs.

[0042] In the above structure, the meshing area of ​​the bevel gears is large and the contact stress is evenly distributed, which is conducive to achieving smooth and efficient transmission and reducing energy loss. Secondly, through the mutual engagement of the bevel gears, the change of transmission direction can be achieved within a limited space, making the overall structure more compact and suitable for installation in space-constrained equipment. It should be noted that the transmission method of the second transmission component is not limited to the above structure, and any other method that can achieve horizontal rotation of the cleaning head 224 at the bottom of the box body 221 is acceptable.

[0043] In some possible embodiments, an effective lubrication system can be designed into the bevel gear transmission mechanism, such as oil spray lubrication or oil bath lubrication, to reduce friction, wear, and heat generation, thereby improving transmission efficiency and service life. Seals can also be provided on the output shaft and at the connection between the output shaft and the housing 221 to prevent lubricant leakage and the ingress of foreign matter, thereby ensuring clean and normal operation of the transmission mechanism.

[0044] Reference Figure 1 In some embodiments of the present invention, the frame component 110 includes a push rod body 112 and a rotating shaft 113, and the two ends of the rotating shaft 113 are respectively rotatably connected to the two measuring wheels 120; one end of the push rod body 112 is connected to the rotating shaft 113, and the other end is provided with a handle 111.

[0045] Specifically, the push rod body 112 is arranged vertically, so that the handle 111 is at a normal grip height, which is convenient for the worker to push. In some possible embodiments, the height of the push rod body 112 can be set to be adjustable, so that it can be adjusted to an appropriate height according to the height of the worker, which is convenient for the worker to push. In other possible embodiments, a protective cover can be provided on the handle 111.

[0046] Figure 4 The schematic diagram of the structure of the cleaning component of the measuring device provided by the embodiment of the utility model is illustrated. Figure 1 and Figure 4 The measuring device also includes a cleaning assembly 300, which is mounted on the suspension beam 210 and is used to remove foreign matter from the measuring wheel 120. The cleaning assembly 300 includes a mounting base 310, which is detachably mounted on the suspension beam 210 and is provided with a scraper 320. The scraper 320 extends in front of the measuring wheel 120 and has a gap between the scraper 320 and the measuring wheel 120.

[0047] Specifically, the mounting base 310 is a U-shaped structure, its dimensions matching those of the suspension beam 210. Both the suspension beam 210 and the mounting base 310 are provided with threaded holes, allowing bolts to detachably connect the mounting base 310 to the suspension beam 210. Two cleaning assemblies 300 can be provided, one corresponding to each of the two measuring wheels 120. A scraper 320 is located in front of the measuring wheel 120. When foreign matter adheres to the measuring wheel 120, the scraper 320 contacts the foreign matter, removing it from the measuring wheel 120.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
