[0027] The limiting component 3 is used to limit the upward and downward movement range of the square steel tube 21, the limiting component 3 includes a limiting plate 31, a tapered groove 32 and a pushing block 33, the tapered groove 32 is arranged at the bottom of the limiting plate 31, the end of the tapered groove 32 protrudes into the vertical slide 12, the limiting plate 31 and the tapered groove 32 are slidingly connected to the vertical slide 12, the bottom of the pushing block 33 is slidingly connected to the tapered groove 32, when the pushing block 33 moves towards the tapered groove 32, the tapered groove 32 is pushed by the pushing block 33 to bend towards the inner wall of the vertical slide 12, so that the tapered groove 32 extrudes the vertical slide 12, and then limits the movement of the limiting plate 31, when the square steel tube 21 which can slide moves to the limiting plate 31, the square steel tube 21 cannot move upward and downward.

[0028] The top of the pushing block 33 is slidingly connected to the limiting plate 31, the rear end of the limiting plate 31 is provided with a bolt 311, the rear end of the pushing block 33 is provided with an upward protruding vertical rod, the vertical rod of the pushing block 33 is slidingly connected to the bolt 311, the bolt 311 limits the horizontal movement of the pushing block 33, and ensures that the front end of the pushing block 33 can be inserted into the tapered groove 32, and the bolt 311 is screwed with a locking ring 312, when the pushing block 33 needs to be fixed in position, the locking ring 312 is screwed to tightly contact the vertical rod of the pushing block 33.

[0029] The measuring arm 4 includes a fixed arm 41 and a telescopic arm 42, the telescopic arm 42 is slidingly connected to the fixed arm 41, and the fixed arm 41 is slidingly connected to the slide rail 211, when the fixed arm 41 is connected with the slide rail 211, the top surface of the fixed arm 41 is in the same horizontal plane as the top surface of the square steel tube 21, and the value of the scale line on the plane is the distance between the bottom surface of the telescopic arm 42 and the bottom of the measuring scale 1.

[0030] The telescopic arm 42 is also equipped with scale lines. The front end of the fixed arm 41 is screwed with a fastening button 411. The bottom of the fastening button 411 presses the telescopic arm 42. When it is necessary to measure the C value of the highway guardrail, the telescopic arm 42 is extended to the lowest range of the C value. Then the fastening button 411 is tightened to fix the length of the telescopic arm 42. Then the measuring ruler 1 is moved along the curb. If the guardrail does not collide with the telescopic arm 42, it means that the C value of the guardrail is qualified.

[0031] like Figure 4 As shown, the telescopic arm 42 has an equipment slot 421 at its front end, which opens downwards. A rangefinder 422 is rotatably connected to the equipment slot 421. Without external force, the rangefinder 422 remains vertically upright under gravity. A display 212 is mounted on the square steel tube 21 and is connected to the rangefinder 422. During use, the telescopic arm 42 is placed on the guardrail, and the value displayed on the display 212 is the height of the guardrail. A directional plate 423 is rotatably connected to the bottom rear end of the equipment slot 421. The directional plate 423 can magnetically attract the front end of the equipment slot 421. When the directional plate 423 is in contact with the equipment slot 421, the probe of the rangefinder 422 is adjusted by the directional plate 423 to face forward. At this time, the value displayed on the display 212 plus the scale of the telescopic arm 42 is the C value of the guardrail.

[0032] The top of the front end of the telescopic boom 42 is equipped with a guide wheel 424, which contacts the guardrail. When measuring the height of the middle of the guardrail, the guide wheel 424 is pressed against the middle of the guardrail, and then the guide wheel 424 is pushed to move. When the guide wheel 424 deviates from the guardrail, the abnormal position is recorded and repaired.

[0033] The moving plate 5 has wheels 51 at its bottom and a threaded rod 52 at its top. The measuring ruler 1 has a threaded hole 13 at its bottom, and the threaded rod 52 is screwed into the threaded hole 13. When performing long-distance testing, the threaded rod 52 is inserted into the threaded hole 13 to connect the moving plate 5 to the measuring ruler 1. Pushing the moving plate 5 can maintain the stability of the route and save effort.

[0034] When measuring the height of the guardrail, the telescopic arm 42 is placed above the guardrail, and the height value can be obtained through the measuring ruler 1 and the display 212. When checking whether the height meets the standard, the position of the square steel pipe 21 is fixed so that the telescopic arm 42 is at the lowest value of the standard height. Then, it is extended directly to the guardrail. If the telescopic arm 42 passes smoothly, it means that the height at that point is insufficient. When inspecting a long distance in a section, the clamp 22 is loosened, and the two limit plates 31 are fixed to the highest and lowest standard positions. Then, the telescopic arm 42 is placed on the guardrail, and the moving plate 5 is moved. If the square steel pipe 21 conflicts with the limit plate 31, it means that this point is unqualified. The rangefinder 422 can also record the undulation of the guardrail over this distance. After the telescopic arm 42 is locked, the C value of the guardrail can also be checked to see if it meets the standard.

[0035] It should be pointed out finally that: the above only for the preferred embodiments of the utility model have, and do not for limiting the utility model, although the utility model has been described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features.
