Description

Technical Field

[0001] This utility model relates to the field of testing tools, and in particular to a simple and portable guardrail testing tool. Background Technology

[0002] After repairs, the guardrails on highways require measurement of their height and C-value. The C-value refers to the distance from the guardrail surface to the curb surface, generally not less than 50cm, to provide sufficient safety distance for vehicles and reduce damage in the event of a collision. Maintenance personnel need to use both a spirit level and a ruler for measurement, which is more difficult when encountering areas with rapid flow channels in the stop areas. Furthermore, at least two workers are required for measurement, and the results are significantly affected by human factors, leading to relatively poor accuracy.

[0003] Existing patent CN202311676241.3 discloses a continuous measuring device for highway guardrail height, comprising: a column; a swing frame assembly including a first swing frame rod, a second swing frame rod, a third swing frame rod, and a first spring rod; a positioning mechanism slidably disposed in a slot and provided with a first reflector indicating the position of the upper edge of the guardrail plate; a linkage frame; a ground support assembly including a first outer rod, a first inner rod, and a spring; and a measuring assembly including an inclination sensor, a first distance sensor, and a second distance sensor. With this device, the measurement process can be performed without personnel operating measuring tools, reducing the workload of measuring personnel, and enabling continuous measurement of guardrail height to obtain more comprehensive highway guardrail height data, better reflecting the overall changes in guardrail height. However, the structure of the aforementioned patent is very complex, its portability is poor, and the measurement cost is relatively high. Utility Model Content

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] like Figure 1 - Figure 6 As shown, a simple and portable guardrail inspection tool includes a vertical pole 1, which is made of stainless steel and has good corrosion resistance. A base 12 is welded to the bottom of the vertical pole 1 to support it. Several reinforcing plates 13 are welded to the upper surface of the base 12 and fixed to the vertical pole 1 to improve the connection strength between the base plate and the vertical pole 1. The base 12 improves the stability of the vertical pole 1 when placed on the ground. A rubber anti-slip pad 14 is glued to the bottom surface of the base 12 to improve its anti-slip properties.

[0029] A displacement grating ruler sensor for measuring the height of the guardrail is installed on one side of the vertical pole 1. The fixed part 2 of the displacement grating ruler sensor is fixed to one side of the vertical pole 1 along its length. The moving part 3 of the displacement grating ruler sensor is fixed to a sliding structure. The height is measured by the distance the moving part 3 slides on the fixed part 2. The measuring distance of the displacement grating ruler sensor is the distance between the bottom surface of the anti-slip pad 14 and the bottom surface of the moving part 3. The measurement accuracy of the displacement grating ruler sensor is ±1mm, which meets the measurement accuracy requirements of the guardrail. The moving part 3 is electrically connected to the display 11 via a wire, and the reading of the displacement grating ruler sensor is directly displayed on the display 11, making it convenient to use.

[0030] A sliding structure is installed on the vertical rod 1. The side of the base 12 near the vertical rod 1 where the sliding structure is installed is flush with the surface of the vertical rod 1, facilitating the measurement of the guardrail by the vertical rod 1. The sliding structure includes a slide block 4, with a fixed part 2 fixed on the slide block 4. The slide block 4 is located outside the moving part 3. A guide rail 5 is fixedly installed on the vertical rod 1 to guide the movement of the slide block 4. A positioning block 6 is fixedly installed in the middle of the vertical rod 1, located at the bottom of the guide rail 5. The height of the positioning block 6 is lower than the general height of the guardrail. The positioning block 6 blocks and positions the slide block 4, preventing it from slipping off the guide rail 5 and facilitating the movement of the measuring structure via the slide block 4. It also provides some space for the measuring structure, improving the portability of the testing tool. A stop block is fixedly installed at the top of the guide rail 5 to prevent the slide block 4 from slipping off the guide rail 5.

[0031] The measuring structure for measuring the C-value of the guardrail is mounted on the slide block 4. The measuring structure includes a horizontal bar 9 and a slide bar 10, with the slide bar 10 located outside the horizontal bar 9. Both the horizontal bar 9 and the slide bar 10 are made of stainless steel. A groove 15 is provided on the outer wall of the horizontal bar 9, and a slide rail 16, adapted to the groove 15, is provided on the inner wall of the slide bar 10. The slide rail 16 is located within the groove 15 and slides along it. A scale is provided on the horizontal bar 9, with the starting graduation of the scale being the distance from the side of the vertical bar 1 closest to the horizontal bar 9 to the scale, facilitating the measurement of the C-value. The measured C-value of the guardrail is the length of the slide bar 10 plus the graduation of the scale.

[0032] A baffle 19 is fixedly installed on the upper surface of the end of the crossbar 9 away from the vertical bar 1, and a positioning plate 18 is fixedly installed on the end of the slide bar 10 near the vertical bar 1. The positioning plate 18 and the baffle 19 prevent the slide bar 10 from slipping off the crossbar 9. A mounting seat 8 is provided on the slide block 4. The mounting seat 8 is hinged to one end of the crossbar 9 via a pivot 17, which facilitates the folding of the crossbar 9 and the slide bar 10, improving the portability of the testing tool. A limiting plate is fixedly installed on the top of the mounting seat 8 to limit the horizontal movement of the crossbar 9, ensuring the horizontality of the crossbar 9 during measurement and improving the convenience of use and the accuracy of measurement.

[0033] A horizontal bubble 7, which is circular, is fixed to the top of the vertical rod 1 by adhesive. The verticality of the vertical rod 1 is detected by the horizontal bubble 7. Placing the horizontal bubble 7 at the top of the vertical rod 1 makes it easy to observe the state of the horizontal bubble 7.

[0034] In use, place the vertical bar 1 on the road surface, rotate and open the horizontal bar 9, and pull the horizontal bar 9 upward to slide the sliding bar 10 off the horizontal bar 9. The lower surface of the sliding bar 10 contacts the top of the guardrail. Adjust the verticality of the vertical bar 1 using the bubble level 7, and read the height of the guardrail directly from the display 11. Slide the sliding bar 10 until its end contacts the guardrail surface, and read the C value of the guardrail directly from the scale on the horizontal bar 9.

[0035] The inspection tool described in this invention requires only one worker to inspect the guardrail panels. It is convenient to use, saves manpower, reduces the impact of human factors, and effectively improves the accuracy of the inspection. Using this tool, the height and C-value of the guardrail panel can be detected within 50 seconds, thus improving inspection efficiency.

[0036] Therefore, the simple and portable guardrail detection tool described in this utility model can solve the problems of complex structure and poor portability of existing measuring devices.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
