Description

Highway guardrail height measurement device Technical Field The application relates to the technical field of measuring tools, in particular to a highway guardrail height measuring device. Background The highway guardrail is a guardrail with isolation and protection functions, absorbs collision energy by utilizing deformation of soil bases, upright posts and cross beams, forces out-of-control vehicles to change directions and restore to normal running directions, and is widely applied at present. In the construction process and the trade inspection of highway guardrail, guardrail crossbeam central height measurement is an indispensable parameter to ensure that it accords with the safety standard, avoid leading to unable deformation absorption collision energy because of the altitude is not enough, or the too high effective isolation effect that can't play, influence driving safety, the present height measurement main altitude chi to highway guardrail combines the horizon rule to measure, for example, the patent of publication number CN221349916U discloses a wave form guardrail height measurement instrument, this patent is through setting up sleeve and telescopic link, realize quick accurate measurement, and can also fold the horizontal pole after using, save the transportation space. However, in the implementation process of the technical scheme, although the quick measurement can be realized through the cooperation of the telescopic rod and the sleeve, when the measurement is performed, fine adjustment cannot be realized in the process of operating the telescopic rod, the measurement accuracy can be limited by the telescopic length of the telescopic rod, so that the error is large, the accuracy of the measurement result is influenced, the existing specification requires that the center height of the cross beam, namely the height from the middle position of the waveform guardrail to the edge of the road surface, is required to be detected for the steel guardrail, but the middle position of the waveform guardrail is determined by visual inspection and then is measured by adopting a steel tape measure, and thus, the problem of detection is that the middle position is difficult to determine or is inaccurate, so that the detection result is distorted. It is necessary to provide a highway guardrail height measuring apparatus to solve the above-mentioned problems. It should be noted that the above information disclosed in this background section is only for understanding the background of the inventive concept and, therefore, it may contain information that does not constitute prior art. Disclosure of Invention Based on the problems in the prior art, the application aims to provide the highway guardrail height measuring device, which can realize height fine adjustment and improve measurement accuracy by arranging racks and gears. The technical scheme adopted by the application for solving the technical problems is that the highway guardrail height measuring device comprises: A longitudinal axis; the first sleeve is in sliding connection with the longitudinal shaft and is provided with a groove; A second sleeve fixed on the longitudinal axis, the second sleeve having a groove thereon; the graduated scale is arranged in the groove, one end of the graduated scale is fixed with the second sleeve, and the other end of the graduated scale is in sliding connection with the first sleeve; the vernier is arranged on the first sleeve; the level gauge is vertically fixed with the longitudinal axis; the rack is arranged on the back of the graduated scale; the gear is arranged in the first sleeve and meshed with the rack; the knob is fixed with the rack.
