[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. 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 belong to the protection scope of the present invention.

[0025] As Figure 1 、 Figure 2 and Figure 4 , a road gradient measuring device includes a first measuring rod 1 and a second measuring rod 2 arranged above the stepped surfaces of different heights of a stepped road. The first measuring rod 1 is located on the lower step, and the second measuring rod 2 is located on the higher step, capable of cooperating to measure the gradient of the stepped road. A horizontal bracket 3 is installed on the second measuring rod 2. Two fixed blocks 4 are fixedly connected to the bottom of the horizontal bracket 3, and a protractor 5 is fixedly connected to the bottom of the fixed block 4. The protractor 5 is an inverted semi-circular shape;

[0026] As Figure 4 and Figure 5 , a connecting block 6 is fixedly connected to one side of the horizontal bracket 3, a connecting shaft 7 is fixedly connected to the connecting block 6, a gradient measuring rope 8 is fixedly connected to one side of the first measuring rod 1, and the end of the gradient measuring rope 8 away from the first measuring rod 1 penetrates through the connecting shaft 7 and extends to the outside of the connecting shaft 7. The lengths of the first measuring rod 1 and the second measuring rod 2 are the same. The position of the entrance of the gradient measuring rope 8 on the connecting shaft 7 and the center of the arc of the protractor 5 are at the same height and aligned. The relative height of this position on the second measuring rod 2 is the same as the relative height of the gradient measuring rope 8 on the first measuring rod 1, so that when the first measuring rod 1 and the second measuring rod 2 are on a horizontal road surface, the gradient measuring rope 8 between the connecting shaft 7 and the first measuring rod 1 can remain horizontal. When there is a gradient on the road surface, the gradient measuring rope 8 between the connecting shaft 7 and the first measuring rod 1 is parallel to the ground gradient.

[0027] The slope measuring rope 8 is fixedly connected with a limiting sleeve rod 9 at one end passing through the connecting shaft 7. There is an opening on the connecting shaft 7 to facilitate the passing of the slope measuring rope 8. By pulling the limiting sleeve rod 9, the length of the slope measuring rope 8 between the first measuring rod 1 and the second measuring rod 2 can be adjusted, enabling slope measurement when the first measuring rod 1 and the second measuring rod 2 are at different distances.

[0028] As Figure 1 and Figure 2 show, support footrests 10 are provided at the bottoms of the first measuring rod 1 and the second measuring rod 2. The bottoms of the first measuring rod 1 and the second measuring rod 2 are both threadedly connected to the support footrests 10. External threads are provided at the bottoms of the first measuring rod 1 and the second measuring rod 2, and screw holes are provided at the tops of the support footrests 10 to achieve the threaded connection of the first measuring rod 1, the second measuring rod 2 and the support footrests 10 at their bottoms. The stability of the first measuring rod 1 and the second measuring rod 2 is improved by using the support footrests 10, enabling the first measuring rod 1 and the second measuring rod 2 to be vertically set on the road.

[0029] The support footrests 10 at the bottoms of the first measuring rod 1 and the second measuring rod 2 are both located above the edges of the corresponding step surfaces, ensuring that the relative positions of the first measuring rod 1 and the second measuring rod 2 on different step surfaces remain consistent, making the measured slope more accurate.

[0030] As Figure 2 and Figure 3 show, a threaded hole 11 is provided at the top of the second measuring rod 2. A vertical circular hole 12 is provided at the bottom of the inner wall of the threaded hole 11. The centers of the threaded hole 11 and the vertical circular hole 12 are both located at the center of the second measuring rod 2.

[0031] As Figure 2 and Figure 3 show, a fixing ring 13 is provided at the top of the second measuring rod 2. A threaded shaft 14 that cooperates with the threaded hole 11 is fixedly connected to the bottom of the fixing ring 13. A fixing rod 15 is fixedly connected to the bottom of the threaded shaft 14.

[0032] As Figure 2 and Figure 3 show, one end of the transverse bracket 3 passes through the second measuring rod 2 and extends to the outside of the second measuring rod 2. There is an opening on the second measuring rod 2 to facilitate the passing of the transverse bracket 3. An arc-shaped limiting plate 16 is fixedly connected to the transverse bracket 3. The arc-shaped limiting plate 16 is in contact with the surface of the second measuring rod 2, capable of restricting the position of the transverse bracket 3 passing through the second measuring rod 2 to achieve the positioning of the transverse bracket 3. The bottom of the fixing rod 15 passes through the transverse bracket 3. There is an opening on the transverse bracket 3 to facilitate the passing of the fixing rod 15. When the arc-shaped limiting plate 16 is in contact with the surface of the second measuring rod 2, the opening on the transverse bracket 3 is aligned with the vertical circular hole 12 in the vertical direction.

[0033] AsFigure 2 A limiting ring 17 is fixedly connected to the top of the first measuring rod 1, a counterweight 18 is embedded and fixed on the transverse bracket 3, the counterweight 18 and the protractor 5 are respectively arranged on both sides of the second measuring rod 2, and the counterweight 18 can balance the gravity at both ends of the transverse bracket 3 to improve the stability of the transverse bracket 3.

[0034] The working principle of a road slope measuring device provided by the utility model is as follows:

[0035] When the fixing ring 13 is rotated counterclockwise to drive the threaded shaft 14 to rotate counterclockwise, the fixing rod 15 can be driven to move up and disengage from the vertical circular hole 12. At this time, one end of the transverse bracket 3 can be passed through the second measuring rod 2, or the transverse bracket 3 can be removed from the second measuring rod 2, and then the fixing ring 13 is rotated clockwise to drive the threaded shaft 14 to rotate clockwise. The threaded shaft 14 is threadedly connected to the threaded hole 11, and the fixing rod 15 passes through the vertical circular hole 12 and the transverse bracket 3, completing the installation or disassembly of the transverse bracket 3.

[0036] When it is necessary to measure the slope of a stepped road, first install the transverse bracket 3 on the second measuring rod 2, then set the first measuring rod 1 and the second measuring rod 2 above the stepped surfaces of different heights of the stepped road, manually pull the limiting sleeve rod 9 to one side to straighten the slope measuring rope 8, and at this time the slope measuring rope 8 is parallel to the slope surface of the stepped road;

[0037] The angle formed by the slope measuring rope 8 and the top plane of the protractor 5 is the slope of the stepped road surface to be measured.

[0038] After the slope measurement is completed, the transverse support 3 can be disassembled, and the slope measurement rope 8 can be wound around the first measuring rod 1 to facilitate carrying of the measuring device.

[0039] Compared with the related art, the road slope measuring device provided by the utility model has the following beneficial effects:

[0040] The utility model arranges the first measuring rod 1 and the second measuring rod 2 above the step surfaces of different heights of the stepped road, and manually pulls the slope measuring rope 8 so that the slope measuring rope 8 is in a straightened state. At this time, the slope measuring rope 8 and the road surface of the stepped road remain parallel. The inclination of the slope measuring rope 8 is read by the protractor 5, and the slope of the stepped road can be measured. When the slope measurement is not performed, the slope measuring rope 8 can be wound around the first measuring rod 1, which is convenient for carrying and transporting the measuring device.

[0041] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and what is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the present utility model claimed.
