Description

Technical Field

[0001] The invention relates to the technical field of road slope inclination detection, and in particular to a road slope detection device. Background Art

[0002] Road slope detection is an important part of ensuring safe road operation. It can promptly detect various problems on road slopes, so that timely intervention and repair can be carried out, ensuring the safety of vehicles and people on the road.

[0003] Its testing items cover multiple aspects to ensure the stability of the slope. Among them, the detection of road slope gradient is a basic testing item stipulated in the highway engineering quality inspection and assessment standards. Once the design slope of the slope is determined, if it exceeds the specified value during the construction process, it will cause an increase in the occupied area and economic cost problems of the cross section; if it does not reach the specified value, it will affect the stability of the roadbed and bury quality risks. At present, the most commonly used method for road slope detection is to use a spirit level with a steel tape measure for measurement. The detection accuracy is not high, and 2-3 people must be present at the same time to complete the measurement, which is inconvenient for road slope detection.

[0004] The Chinese invention patent with patent application number CN202322780137.0 records a road slope detection device, which is installed and fixed on the road slope to be detected by setting a base plate, and is used to adjust the angle of the support rod through an angle adjustment component. The angle of the support rod is adjusted to a vertical state, and then the slope detection mechanism is installed on the fixed rod. The road slope is detected by the slope detection mechanism. The adjustable angle between the support rod and the base plate is suitable for installing the slope detection mechanism at any position on the road slope for detection, thereby improving applicability and detection accuracy. However, each time the above-mentioned detection device performs slope gradient detection, the base plate needs to be inserted into the slope. After the detection is completed, the base plate needs to be pulled out from the slope, and then the base plate needs to be inserted into the slope again during the next detection. This is time-consuming, reduces the efficiency of slope gradient detection work, and increases the labor intensity of the staff. Summary of the invention

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example 1

[0035] The inclination adjustment component 3 is used to adjust the inclination of the base plate 1;

[0036] The slope detection assembly 4 includes a first straight rod 41 and a second straight rod 42 movably plugged into the top of the bottom plate 1. The bottom ends of the first straight rod 41 and the second straight rod 42 penetrate the bottom plate 1 and are both connected to the universal roller 2. The slope detection assembly 4 also includes an angle measurement unit 43. The angle measurement unit 43 measures the slope of the slope side through the height difference between the first straight rod 41 and the second straight rod 42.

[0037] The fine detection component 5 is used to detect the slope of a smaller span on the slope edge.

[0038] refer to Figure 1-Figure 5 The inclination adjustment component 3 includes four first electric push rods 31, which are respectively fixedly connected to the four corners of the bottom of the base plate 1, and the four universal rollers 2 are respectively fixedly connected to the output ends of the four first electric push rods 31. The inclination adjustment component 3 also includes a spirit level fixedly connected to the top surface of the base plate 1.

[0039] Specifically, the base plate 1 can be adjusted to a horizontal position quickly and accurately by adjusting the extension lengths of the four first electric push rods 31 respectively and observing the level meter, thereby ensuring that the slope detection work can be carried out accurately and smoothly, thereby improving the accuracy and efficiency of the detection work.

[0040] refer to Figure 1-Figure 5 The angle measuring unit 43 includes a first rotating rod 431 and a second rotating rod 432 fixedly connected to the front sides of the first straight rod 41 and the second straight rod 42. The front end of the second rotating rod 432 is rotatably connected to a rotating plate 433. A sliding cavity 434 is provided on the front side of the rotating plate 433. The front end of the first rotating rod 431 extends into the interior of the sliding cavity 434 and is slidably connected in the sliding cavity 434. An alignment line 435 is fixedly connected to the front side of the rotating plate 433. The left end of the alignment line 435 coincides with the axis line of the second rotating rod 432. The alignment line 435 is parallel to the line connecting the centers of the front ends of the first rotating rod 431 and the second rotating rod 432. The front side of the second straight rod 42 is fixedly connected to an angle measuring ruler 436 through a connecting rod. The front side of the angle measuring ruler 436 is provided with angle scale lines.

[0041] Specifically, since the top surface of the slope has a slope, the two universal rollers 2 at the bottom ends of the first straight rod 41 and the second straight rod 42 are located at different heights, so that there is a height difference between the first rotating rod 431 and the second rotating rod 432, so that the rotating plate 433 is tilted. In this way, the slope value of the top surface of the lower slope can be accurately detected by observing the angle scale line on the angle measuring ruler 436 aligned with the alignment line 435. In this way, the slope detection work of the slope can be completed by adjusting the bottom plate 1 to a horizontal position, which effectively improves the efficiency of the slope detection work and reduces the labor intensity of the staff.

[0042] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 The fine detection component 5 includes a through slot 51 opened on the top of the bottom plate 1, a fixed sleeve 52 is fixedly inserted at the right end of the through slot 51, a movable sleeve 53 is slidably connected between the front and rear inner walls of the through slot 51 through a slider and a slide slot, the first straight rod 41 and the second straight rod 42 are movably inserted in the fixed sleeve 52 and the movable sleeve 53 respectively, the fine detection component 5 also includes a movable unit 54 and a fixed component 55, the movable unit 54 is used to drive the movable sleeve 53 to slide left and right in the through slot 51, and the fixed component 55 is used to fix the position of the movable sleeve 53.

[0044] Specifically, the movable sleeve 53 is driven by the movable unit 54 to move left and right in the through groove 51, thereby driving the second straight rod 42 to move left and right. In this way, the distance between the first straight rod 41 and the second straight rod 42 can be adjusted, and then the corresponding slope value can be detected within a smaller slope span range, thereby effectively improving the detection accuracy and greatly improving the practicability and reliability of the detection equipment.

[0045] refer to Figure 1-Figure 5 The first straight rod 41 and the second straight rod 42 are rectangular square rods.

[0046] Specifically, the first straight rod 41 and the second straight rod 42 can be prevented from rotating, thereby ensuring that the detection work can be carried out more reliably and smoothly.

[0047] Example 2

[0048] According to Example 1, please refer to Figure 1-Figure 6The movable unit 54 includes a first elastic member fixedly connected between the left side surface of the movable sleeve 53 and the left inner wall of the through groove 51.

Two take-up wheels 542 are symmetrically fixedly sleeved on the outer peripheral surface of the rotating tube 541. Two pull ropes 543 are symmetrically fixedly wound around the two take-up wheels 542. The movable unit 54 also includes two pull plates 544 symmetrically fixedly connected to the front and rear sides of the movable sleeve 53. One end of the two pull ropes 543 away from the take-up wheels 542 is symmetrically fixedly connected to the two pull plates 544.

[0049] Specifically, it is only necessary to rotate the rotating tube 541 to drive the two take-up wheels 542 to rotate clockwise or counterclockwise, thereby driving the second straight rod 42 to slide to the right or left along the through groove 51 through the pull rope 543, the pull plate 544 and the first elastic member. In this way, the distance between the first straight rod 41 and the second straight rod 42 can be quickly adjusted to realize the slope detection of different slope spans, further improving the detection efficiency of the equipment.

The two plug plates 57 are symmetrically slidably connected in the two cavities 56, and two groups of partitions 58 are symmetrically fixedly connected on the top of the two plug plates 57. The number of each group of partitions 58 is multiple and is equidistantly distributed along the length direction of the plug plates 57. The top surface of the partition 58 is arc-shaped, and the pull plate 544 can be inserted into the gap between any two adjacent partitions 58 in each group of partitions 58.

[0051] Specifically, the moving distance of the pull plate 544 is limited by multiple partitions 58, so as to ensure the accuracy of the adjustment of the span of the slope top surface, thereby facilitating the statistical and comparative study of the slope detection results, improving the value of the detection results, and further improving the practicality of the equipment.

[0054] Specifically, the resistance of the pulling plate 544 moving between the gaps between different partitions 58 is reduced, the pulling strength of the staff is reduced, and the efficiency of the detection work is improved.

[0055] refer to Figure 6 The distance between any two adjacent partitions 58 in each group of partitions 58 is equal to the width of the pull plate 544 .

[0056] Specifically, it further ensures the accuracy of the span adjustment of the top surface of the slope and ensures the value of the test results.

[0057] refer to Figure 1-Figure 5 , and also includes a lifting component 6, which is used to lift the first straight rod 41 and the second straight rod 42 upward so that the universal roller 2 connected at the bottom ends of the two rods are away from the top surface of the slope.
