[0018] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0019] Example 1: Please refer to Figure 1 - Figure 2 A road slope detection device according to this embodiment includes a first caliper 1 and a second caliper 2. One end of the second caliper 2 is movably connected to the interior of the first caliper 1. A support rod 3 is fixedly connected to the bottom of one end of the first caliper 1. A first level 4 is fixedly connected to the top of one end of the first caliper 1. Two first handles 5 are fixedly connected to both sides of one end of the first caliper 1. A movable measuring rod 6 is movably connected to the interior of one end of the second caliper 2. A limit block 7 is fixedly connected to the top of the limit block 7. A second level 8 is fixedly connected to the top of the limit block 7. Two second handles 9 are fixedly connected to both sides of one end of the second caliper 2.
[0020] When it is necessary to measure the slope of two points on a road, the support rod 3 is placed vertically at the first target point. The bubble inside the first level 4 can be adjusted by the first handle 5 so that the bubble inside the first level 4 is centered, thereby making the support rod 3 vertical and the first caliper 1 horizontal. Then, the second caliper 2 is pulled so that one end of the second caliper 2 is pulled out from the inside of the first caliper 1.
[0021] Secondly, the second caliper 2 will drive the movable measuring rod 6 to move to the second target point, so that the movable measuring rod 6 is placed vertically, and the movable measuring rod 6 is moved up and down so that the bottom of the movable measuring rod 6 contacts the ground. At the same time, the second caliper 2 and the first caliper 1 are kept in a horizontal state. The second level 8 on the top of the limit block 7 can be adjusted by the second grip 9 so that the bubble inside the second level 8 is centered and the movable measuring rod 6 is made vertical. Thus, the horizontal distance between the support rod 3 and the movable measuring rod 6 can be calculated through the scale sizes on the surfaces of the first caliper 1 and the second caliper 2. At the same time, the height difference between the movable measuring rod 6 and the support rod 3 after the movable measuring rod 6 moves up and down can be calculated through the scale sizes on the outside of the movable measuring rod 6, so that the drop slope of the two points on the measured road can be calculated.
[0022] Furthermore, the bottom of the support rod 3 is fixedly connected to a first earth-breaking cone 301, and the bottom of the movable measuring rod 6 is fixedly connected to a second earth-breaking cone 601. By providing the first earth-breaking cone 301 and the second earth-breaking cone 601, it is convenient to position the support rod 3 and the movable measuring rod 6, and it is also convenient to adjust the verticality of the support rod 3 and the movable measuring rod 6.
[0023] Furthermore, a movable groove 10 is formed at one end of the second caliper 2, and a movable measuring rod 6 is movably connected to the inside of the movable groove 10. By moving the movable measuring rod 6 up and down in the movable groove 10, the height difference between the support rod 3 and the movable measuring rod 6 can be determined.
[0024] Furthermore, a handwheel 11 is provided at one end of the second caliper 2, and a threaded rod 12 is fixedly connected to one side of the handwheel 11, and one end of the threaded rod 12 is in contact with the outside of the movable measuring rod 6. A threaded groove 13 is processed at one end of the second caliper 2, and one end of the threaded rod 12 is threadedly connected to the inside of the threaded groove 13. By rotating the handwheel 11, the handwheel 11 drives the threaded rod 12 to rotate, and the threaded rod 12 will move along the inside of the threaded groove 13, so that one end of the threaded rod 12 moves to the inside of the movable groove 10 and contacts the movable measuring rod 6, thereby facilitating the fixing of the movable measuring rod 6.
[0025] Furthermore, one end of the first caliper 1 is hingedly connected to two first supporting legs 14 at the bottom, and the bottom end of the first supporting leg 14 is movably connected to the second supporting leg 15 inside, and the bottom of the second supporting leg 15 is fixedly connected to the third earth-breaking cone 16. After the support rod 3 is placed vertically at the first target point, the two first supporting legs 14 are opened, so that the two first supporting legs 14 are separated outward to form a triangle, and the second supporting leg 15 is pulled outward at the same time, so that the second supporting leg 15 drives the third earth-breaking cone 16 to contact the ground, thereby fixing the first caliper 1. The first caliper 1 can be adjusted to a horizontal state through the first level 4, so that the second caliper 2 is pulled outward, and the second caliper 2 will drive the movable measuring rod 6 to move, so that the movable measuring rod 6 can measure multiple points on the moving route of the second caliper 2 when it is moving. The operation is simple and convenient, and multiple sets of data make the detection results more accurate.
[0026] Working principle: By placing the support rod 3 vertically at the first target point, and then adjusting the bubble inside the first spirit level 4 to be centered, the support rod 3 is vertical, and at the same time the first caliper 1 is horizontal, and then pulling the second caliper 2, the second caliper 2 will drive the movable measuring rod 6 to move to the second target point, so that the movable measuring rod 6 is placed vertically, and by moving the movable measuring rod 6 up and down, the bottom of the movable measuring rod 6 is in contact with the ground, and by adjusting the bubble inside the second spirit level 8 to be centered, the movable measuring rod 6 is vertical, and at the same time the second caliper 2 and the first caliper 1 are kept horizontal, so that the horizontal distance between the support rod 3 and the movable measuring rod 6 can be calculated, and at the same time the height difference between the movable measuring rod 6 and the support rod 3 after the up and down movement is calculated, and then the drop slope of the two points of the measured road can be calculated.
[0027] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
