Reticule thickness measuring instrument

Abstract

The invention discloses a tester for the thickness of a marked line. The tester comprises a movable measuring platform, a sliding post, a vertical post and a high-accuracy measuring meter. The movable measuring platform is connected with the lateral wall of the sliding post; a sliding groove is arranged in the vertical post and the sliding post is arranged in the sliding groove; and the high-accuracy measuring meter is fixed on the vertical post, and the measuring head of the high-accuracy measuring meter is tightly contacted with the post head of the sliding post. The invention has the advantages of simple operation, high accuracy and tiny error. The tester provides convenience to the quality control of the construction, the field management of the supervision and the acceptation of the project. The tester is suitable for the maintenance and construction of the modern road and reduces the disturbance and the potential safety hazard for the urban traffic.

Description

technical field [0001] The invention relates to a road surface measuring device, in particular to a marking line thickness tester. Background technique [0002] In today's society, the traditional marking line thickness test uses calipers, feeler gauges, and even manual measurement methods such as the coin comparison method. The test accuracy is poor and the error is large, the operation is troublesome, and the human error is large, and it is impossible to detect whether the road surface is qualified. Due to the inability to accurately detect, some markings are too thin and worn out after being used for a period of time, which will cause road traffic chaos, have potential safety hazards, and slow down the development of modernization. Due to the above shortcomings, the existing equipment and measurement methods can no longer meet the quality control of construction, on-site supervision of supervisors, and acceptance of projects, let alone the needs of road maintenance and co...

Problems solved by technology

[0002] In today's society, the traditional marking line thickness test uses calipers, feeler gauges, and even manual measurement methods such as the coin comparison method. The test accuracy is poor, the operation is troublesome, and the human error is large, and it is impossible to detect whether the road surface is qualified.

Due to the inability to accurately detect, some markings are too thin to be used for a period of time, and they will wear off, which will cause road traffic chaos, pose safety hazards, and slow down the development of modernization.

Due to the above shortcomings, the existing equipment and measurement methods can no longer adapt to the quality control of construction, on-site supervision of supervision, and acceptance of projects, let alone the needs of road maintenance and construction
