Description

Technical Field

[0001] The utility model relates to the technical field of road surface structure depth measurement, in particular to a circular sand-laying device using a manual sand-laying method. Background Art

[0002] The structural depth of the road surface is an important indicator of road roughness. It refers to the average depth of the open pores on the uneven road surface of a certain area. It is mainly used to evaluate the macro-roughness, drainage performance and skid resistance of the road surface. Spread fine sand on the road surface, calculate the ratio of the volume of sand embedded in the uneven surface gaps to the coverage area, and then find the structural depth. The existing manual sand spreading method is to first measure a certain amount of sand with a sand measuring cylinder, pour it on the road surface to be tested, and then use a push plate with a rubber pad on the bottom to repeat the rotating paving action from the inside to the outside, so that the sand fills the gaps on the uneven road surface, pushes the sand into a circle, and no residual sand is left on the surface. After the sand spreading is completed, the outer diameter of the circle is measured, and finally the road surface structural depth is calculated.

Therefore, the existing manual sand spreading method has obvious measurement errors, which in turn affects the measurement accuracy. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figure 1 to Figure 5 , in the embodiment of the present invention, a circular sand spreading device applying the manual sand spreading method includes a retaining wall 1 with a rectangular frame structure;

[0023] Connecting seat 2, the connecting seat 2 is installed at one end of the retaining wall 1, the connecting seat 2 has a "U" - shaped structure, at least one first guide rod 22 is arranged inside the connecting seat 2, and a support frame 21 is integrally formed at one end of the middle part of the connecting seat 2;

[0024] Rotating seat 3, the rotating seat 3 is located above the support frame 21, the bottom of the outer side end of the rotating seat 3 is fixedly connected with a rotating shaft 31, the rotating shaft 31 is rotatably connected with the support frame 21 through a bearing, a limiting groove is opened at the top of the rotating seat 3, and a second guide rod 32 is fixedly connected inside the limiting groove;

[0025] Moving component 4, the moving component 4 is slidably assembled on the second guide rod 32 along the length direction of the second guide rod 32, the moving component 4 includes a moving seat 401, and a sliding hole 403 which is slidably connected with the outer wall of the second guide rod 32 is opened at the lower end of the moving seat 401;

[0026] At least one third guide rod 6, one end of at least one third guide rod 6 is fixedly connected to one side wall of the upper end of the moving seat 401, and the third guide rod 6 and the first guide rod 22 are distributed in a cross - shape;

[0027] The guide seat 7 is disposed between the third guide rod 6 and the first guide rod 22, the lower end of the guide seat 7 is slidably connected to the first guide rod 22, and the upper end of the guide seat 7 is slidably connected to the third guide rod 6;

[0028] The adjusting component 8 is located in the middle of the enclosure 1, and the middle of the adjusting component 8 is connected with a connecting block 5, the connecting block 5 is fixedly connected to the other end of the third guide rod 6, and the lower end of the adjusting component 8 is connected with a pushing component 9.

[0029] In this embodiment: Since the existing manual sand-laying method is to push the sand into a circle as much as possible, the outer diameter of the circle determines the depth of the road surface structure. The existing manual sand-laying method has obvious measurement errors, which in turn affects the measurement accuracy. Therefore, this solution adds a connecting seat 2, a support frame 21, a first guide rod 22, a rotating seat 3, a rotating shaft 31, a second guide rod 32, a moving component 4, a connecting block 5, a third guide rod 6, a guide seat 7, an adjustment component 8 and a flattening component 9 to the inside and outside of the enclosure 1, and uses the above structure to combine into a circular sand-laying device to assist the flattening component 9 in pushing sand to draw a circle, so that the circular outline drawn during the sand-laying process is more standardized, which is convenient for the later measurement of the circular diameter size to be more accurate, thereby avoiding large errors in the obtained road surface structure depth.

[0030] Specifically, before measuring the road surface structure depth by manual sand spreading method, the selected road surface is first cleaned, and then a certain amount of fine sand is measured with a measuring cylinder, and the certain amount of fine sand is poured on the road surface to be measured. Then, the circular sand spreading device of this scheme is placed on the road surface and covered on the outside of the fine sand, so that the fine sand is in the center of the enclosure 1, and the flattening component 9 is on the fine sand pile. After the preparation work is done, the rotating seat 3 is driven to rotate manually. The rotating seat 3 performs circular motion with the rotating shaft 31 as the center and the distance between the center and the moving component 4 as the radius. The moving component 4 in the circular motion state will drive the third guide rod 6 to move. At the same time, the first guide rod 22 and the guide seat 7 will cooperate with the third guide rod 6 to perform horizontal and longitudinal reciprocating motion. The connecting block 5 at the other end of the third guide rod 6 will also perform circular motion with the adjusting component 8 and the flattening component 9. The trajectory of the circular motion is regulated by changing the distance between the rotating shaft 31 and the moving component 4. The sand surface paved by the circular sand paving device in this scheme is uneven and flat, and finally a more standardized circular sand surface can be obtained, which is convenient for measuring more accurate values ​​to further reduce the occurrence of errors.

[0031] Please refer to Figure 3 and Figure 4The moving assembly 4 also includes a handle 402 integrally formed with the moving seat 401, a through hole 404 connected to the sliding hole 403 is formed on the top of the handle 402, a first limiting ring 405 is integrally formed on the inner wall of the middle part of the through hole 404, a limiting rod 406 is arranged inside the through hole 404, the limiting rod 406 passes through the first limiting ring 405 and extends to the top of the sliding hole 403, a pressing block 407 is arranged on the upper end of the limiting rod 406, the lower end of the pressing block 407 is inserted into the upper open end of the handle 402, the outer wall of the limiting rod 406 is sleeved with a first spring 408, and the first spring 408 is located between the pressing block 407 and the first limiting ring 405; a limiting tooth groove 33 is arranged on the outer wall of the upper surface of the second guide rod 32; a limiting tooth matching the limiting tooth groove 33 is arranged at the lower end of the limiting rod 406.

[0032] In this embodiment: the moving assembly 4 in this solution can flexibly control the distance between the rotating shaft 31 and the moving assembly 4. Specifically, the handle 402 can be held by hand, and the pressing block 407 can be pressed with the thumb to make the pressing block 407 compress the first spring 408, and at the same time push the limit rod 406 downward until the lower end of the limit rod 406 is embedded in the limit tooth groove 33 opened on the second guide rod 32, so as to limit the relative displacement between the moving seat 401 and the second guide rod 32, thereby fixing the radius value of the circle drawn. Conversely, the limit of the moving seat 401 can be released by releasing the pressing block 407, and the radius of the circle drawn can be changed by pushing the position of the moving seat 401 on the second guide rod 32, and the operation is flexible and changeable.

[0033] Please refer to Figure 5 The adjusting component 8 includes a tube body 801 with upper and lower openings, an external thread 802 is provided on the middle outer wall of the tube body 801, the tube body 801 is fixedly connected to the connecting block 5 by a nut, a bolt 803 is threadedly connected to the upper open end of the tube body 801, and the lower end of the bolt 803 is connected to a limit block 804, and the limit block 804 is located in the inner cavity of the tube body 801; the pushing and leveling component 9 includes a pushing plate 901, and the upper end of the pushing plate 901 is connected to a connecting rod 902, and the connecting rod 902 Inserted in the lower open end of the tube body 801, the upper end of the connecting rod 902 is integrated with a second limiting ring 903, and the bottom of the push plate 901 is adhered with a rubber pad 904; the adjustment component 8 also includes a second spring 805 located inside the tube body 801, and the second spring 805 is located between the limiting block 804 and the second limiting ring 903; the inner diameter of the upper open end of the tube body 801 is smaller than the outer diameter of the limiting block 804, and the outer diameter of the second limiting ring 903 is larger than the lower open end of the tube body 801.

[0034] In this embodiment: As is known to all, in the existing manual sand spreading method, the sand is pushed gently during the sand spreading process. The force of pushing the sand should not be too large, which will affect the measurement accuracy. Therefore, the force of the adjustment component 8 in this solution given to the flattening component 9 is buffering, so that the problem of excessive pushing force will not be caused during the sand pushing process. Instead, the sand can be pushed evenly, so that the fine sand is evenly spread, further improving the accuracy of the measured value. Specifically, by turning the bolt 803 forward, the limit block 804 is forced to move downward to further compress the second spring 805, and then the reaction force of the second spring 805 on the flattening component 9 will also increase. On the contrary, by turning the bolt 803 in the reverse direction, the limit block 804 is driven to move upward, thereby reducing the rebound force of the second spring 805, and the reaction force of the second spring 805 on the flattening component 9 will also decrease.

[0035] In addition, the present solution also provides an external thread 802 on the middle outer wall of the tube body 801, and the tube body 801 is fixedly connected to the connection block 5 by a nut. By loosening the nut, the position restriction of the tube body 801 is released, and the position height of the tube body 801 relative to the connection block 5 can be adjusted, and the adjusted tube body 801 is then limited and fixed by the nut. The above operation method is mainly convenient for adjusting the relative position height of the push-flattening assembly 9.

[0036] 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 within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
