A concrete road width and thickness measuring vehicle and a measuring method thereof

ActiveCN116499338BMechanical width measurementsMechanical thickness measurements
The application discloses a concrete road width and thickness measuring vehicle and a measuring method thereof, a rotating driver is internally provided with a No.1 motor connected with a rotating bearing, the rotating bearing is connected with a thickness measurer through a horizontal telescopic rod; the rotating driver is connected with a horizontal fixing rod, a vertical supporting rod and a rectangular sliding frame, the rectangular sliding frame is provided with a width measurer; the width measurer moves on the sliding rod and the sliding rail through a circular sliding block and a spherical sliding block respectively and moves through a traction line of a sliding driver; a distance recorder is installed at the bottom of the rotating driver, and an electronic controller controls the rotating driver, the sliding driver and the distance recorder to work wirelessly. The application solves the problems of uneven road surface, transverse and longitudinal inclination and multi-person operation in the width and thickness detection of the concrete road surface, and can greenly, efficiently and accurately measure the width and thickness of different concrete road surfaces.

Method for measuring the tooth width of a negative angle trapezoidal thread and device therefor

ActiveCN115615289BMechanical width measurementsDentistryScrew thread
The application discloses a negative angle trapezoidal thread tooth width measuring method and device, comprising the following steps: 1) confirming the design parameters of thread tooth profile; 2) producing a tooth width standard sample according to the design parameters in step 1); 3) producing a tooth width instrument according to the tooth width standard sample in step 2); 4) zeroing the tooth width instrument with the tooth width standard sample as a reference; 5) measuring the tooth width data of the thread tooth profile by using the tooth width instrument; and 6) converting the measured tooth width data into actual tooth width S. The application realizes quick and accurate negative angle trapezoidal thread tooth width parameter measurement, and operation will be more convenient, quick and accurate.
