Description

Technical Field

[0001] The utility model relates to the technical field of road surface leveling, in particular to a road surface leveling instrument for road construction. Background Art

[0002] Patent No. CN215366701U discloses a municipal road surface level meter. The utility model has a reasonable structural design, is convenient for measurement, can locate the position of the support rod, is convenient to fold, and is highly practical.

[0003] However, the above-mentioned existing municipal road surface level meter moves the device through roller No. 1. When there is a bulge on the road surface, roller No. 2 drives the indicator line to move upward through the lifting rod. When there is a bulge on the road surface, the lifting rod drives the indicator line to move downward under the elastic force of spring No. 1. During the process, the position of the indicator line is observed through the through groove No. 2, and the flatness of the road surface is measured with the cooperation of the scale lines. The device detects ground depressions by rolling roller No. 2 on the road surface. When the depression is large and relatively gentle, it is difficult for roller No. 2 to accurately detect the existence of the depression, resulting in a deviation between the detection result and the actual situation.

[0004] In order to solve the above problems, the utility model provides a road surface leveling instrument for road construction. Utility Model Content

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the utility model, rather than implying that each embodiment of the utility model must have the described feature. In addition, it should be noted that this specification describes many features. Although some features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0021] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments:

[0022] refer to Figure 1-4 A road surface level meter for road construction comprises a support frame 1, a support rod 3 is fixedly connected to the lower end surface of the support frame 1, a first detection plate 4 is fixedly connected to the surface of the support rod 3, a fixing frame 5 is fixedly connected to the bottom end of the support rod 3, a first connecting rod 6 is rotatably connected inside the fixing frame 5, moving wheels 7 are rotatably connected to both symmetrical sides of the first connecting rod 6, two support plates 9 are fixedly connected to the lower end surface of the support frame 1, a second connecting rod 10 is rotatably connected between the two support plates 9, a support block 12 is rotatably connected to one end of the second connecting rod 10, detection wheels 13 are rotatably connected to both symmetrical sides of the support block 12, and a second detection plate 14 is fixedly connected to the upper end surface of the support block 12.

[0023] By providing the first connecting rod 6 , the moving wheel 7 can rotate on the first connecting rod 6 and can make a circular motion through the first connecting rod 6 .

[0024] Furthermore, the upper end surface of the second detection plate 14 is fixedly connected to the second spring 11 , and the top end of the second spring 11 is fixedly connected to the lower end surface of the support frame 1 .

[0025] By providing the second spring 11 , when the detection wheel 13 is subjected to uneven ground, the vibration can be fed back to the second detection plate 14 through the second spring 11 for data recording.

[0026] Furthermore, the number of the support rods 3 is set to four, and the number of the fixing frames 5 matches the number of the support rods 3 .

[0027] Furthermore, the scraper 2 is fixedly connected to the lower end surface of the support frame 1 , and the limit ring 15 is fixedly connected to the upper end surface of the support frame 1 .

[0028] By providing the scraper 2, the scraper 2 can scrape the debris on the road surface to the side of the support frame 1 when the support frame 1 moves, so as to prevent the debris from affecting the detection data.

[0029] Furthermore, the number of the first connecting rods 6 is set to four, and the number of the first connecting rods 6 matches the number of the fixing frames 5 .

[0030] Furthermore, the upper end surface of the first connecting rod 6 is fixedly connected with a first spring 8 , and the top end of the first spring 8 is fixedly connected with the lower end surface of the first detection plate 4 .

[0031] By providing the first spring 8, when the moving wheel 7 is subjected to uneven ground, the vibration can be fed back to the first detection plate 4 through the first spring 8 for data recording.

[0032] The working principle of the utility model is as follows: first, the staff can pull the entire device to the test road surface through the limit ring 15, and then the staff can pull the device forward on the test road surface through the vehicle. When a small pothole appears on the road surface, the detection wheel 13 will drive the support block 12 to move up and down when passing through the pothole, and the force will be fed back to the second detection plate 14 through the second spring 11 for recording. When a larger and relatively gentle depression appears on the road surface, it is difficult for the detection wheel 13 to move obviously. At this time, the moving wheel 7 will drive the first connecting rod 6 to tilt when passing through the groove, and drive the first spring 8 to feedback the force to the first detection plate 4 through the first connecting rod 6, and record the force conditions, so as to accurately detect the large and small depressions on the road surface;

[0033] Compared with the prior art, the first connecting rod 6 squeezes or stretches the first detection plate 4 through the first spring 8, and the first detection can record the force conditions, accurately detect larger grooves on the road surface, and improve the accuracy of the detection.

[0034] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
