Description
Technical field
The utility model relates to a kind of pavement strip thicknessmeter.
Background technology
Pavement strip limits the thickness of graticule in the technical standard of " road traffic marking quality requirements and the detection method " of China.Survey crew, measuring in the process of pavement strip, allows fixing sole plate be placed on graticule by using existing pavement strip thickness gauge to obtain first bending, more mobile thickness measuring piece, then reading from digital dial gauge.In standard, be defined in the number of times of measuring on a transversal section and be not less than 5 places, the necessary bending of staff at least 5 times, makes survey crew very tired so like this, and the efficiency of measurement is low.
Utility model content
The purpose of this utility model is in order to solve above-mentioned technical matters, and a kind of pavement strip thicknessmeter is provided, and ensureing can to reduce labour intensity under the prerequisite that measuring accuracy is high, improves the efficiency of measuring.
For addressing the above problem, the utility model adopts following technical scheme: comprise AD converter and sole plate, one end of described sole plate is fixedly installed cylindrical shell, in cylindrical shell, lower end is provided with measurement piece, thickness measuring piece upper end is provided with self-inductance sensor, self-inductance sensor top is provided with the connecting link being connected with self-inductance sensor, the top of connecting link is provided with digital indicator, self-inductance sensor is connected with the input end of AD converter, and the output terminal of AD converter is connected with digital indicator.
Self-inductance sensor comprises armature, coil and the iron core that can move up and down, and coil winding, on armature, is provided with iron core in coil, and iron core lower end is fixedly connected with thickness measuring piece, and iron core (6) upper end is fixedly connected with connecting link.
Cylindrical shell is stretched out in described connecting link upper end, and stretches out on the connecting link sidewall of cylindrical shell and be provided with for connecting link is carried out to spacing stop screw.
On the sidewall of described cylindrical shell, be also provided with handrail.
Described cylindrical shell is rectangular-shaped structure.
Described sole plate end is provided with back up pad, and back up pad is vertical with sole plate to be arranged, and cylindrical shell is arranged in back up pad.
With respect to prior art, the beneficial effect the utlity model has: the utility model is by arranging sole plate, cylindrical shell is set on sole plate, in cylindrical shell, lower end arranges thickness measuring piece, the upper end of thickness measuring piece is connected with self-inductance sensor, and self-inductance sensor is connected with the digital indicator that is arranged on connecting link top through AD converter, while measuring the thickness of pavement strip, thicknessmeter is placed on pavement strip, carries out reading and can learn the thickness of pavement strip from digital indicator.This utility unit is easy and simple to handle, has reduced tester's labour intensity, and measuring accuracy is high, measures efficiency high.
Further, in the utility model, by stop screw is set, can carry out spacing to connecting link, make initially to make the lower surface of thickness measuring piece and the lower surface of base substrate concordant measuring, when measurement, by adjusting stop screw, can make connecting link free-falling, thickness measuring piece is contacted with meter.In addition, the utility model arranges handrail and is convenient to whole measuring instrument to move.
