Description

Technical Field

[0001] The present application relates to the technical field of calibration of rail detection equipment, and more specifically, to a spacing scale calibrator. Background Art

[0002] The track gauge is a narrow-gauge track detection device. Its structure consists of a ruler body, a scale and a sliding frame on the ruler body. The ruler body is a duplex profile structure in the shape of a square tube. The upper and lower outer edges of the profile have outward extensions. A notch is opened on the inner side of the outer edge. The stainless steel scale is inserted into the notch and then fixed at the end with a pin. A sliding frame is installed in the middle of the ruler body. A secondary ruler and side plates are fixed on the sliding frame. Adjustment bolts are fixed on the side plates. A cross plate and a probe are installed at the end of the ruler body. The entire track gauge is a T-shaped structure. In order to ensure the accuracy of the measurement, the track gauge needs to be calibrated regularly. The common tool for calibrating the track gauge is a calibrator, which can be used for track gauge measurement calibration and superelevation measurement calibration.

[0003] The gauge calibrator is a special detection tool for detecting the railway gauge. The current railway gauge calibrator used in my country has a fixed measuring point structure, that is, several fixed point measuring blocks are installed on the calibrator body, and each measuring block gives a specific position size (usually detection points: 100, 300, 500, 700, 900, 1100, 1290 (mm)) and the installation error of the measuring block. Since this calibrator can only detect several fixed points of the gauge when detecting the gauge, it cannot grasp the measurement status of any point of the gauge, and the measuring block cannot be accurately installed on the measuring point.

[0004] In addition, there are also digital railway rulers, which are commonly used measuring tools for railway turnout inspection, on-site line installation and commissioning, safety management, etc. Its structure mainly includes ruler body, insulating plate and probe, etc. How to use the ruler: Place the front and rear insulating pads on the rail joint, adjust the position of the ruler so that the two positioning screws are in contact with the inner side of the rail, and align one side of the ruler body with one of the rail ends. Use a steel ruler to check the misalignment of the same side of the ruler body at the rear insulating pad and the rail end. The misalignment value measured by the steel ruler is the right-angle misalignment value of the rail.

[0005] There is no relatively unified calibrator for railway square rulers at present. Therefore, when using this kind of fixed point calibrator to detect the distance ruler, it is necessary to correct it according to the installation error of each measuring point, which brings trouble and inconvenience to the calibration work. Utility Model Content

[0008] A distance scale calibrator comprises: a fixed calibrating component and a movable calibrating component;

[0009] The fixed calibration assembly includes a calibration device body, an end measurement plate, and a fixed measurement block.

A plurality of fixed measurement blocks are arranged at intervals along the length direction on the top surface of the calibration device body. The fixed measurement blocks are arranged on the same side of the end measurement plate.

[0010] The movable calibration component includes a slider and an indicator mark arranged on the slider. A scale mark is arranged on the calibrator body, and the indicator mark can be used to read a numerical value through the scale mark.

[0011] Furthermore, the top surface of the fixed measuring block is provided with a groove, the top surface of the end measuring plate is provided with a groove, the grooves on the end measuring plate and the top surface of the fixed measuring block are arranged along the length direction of the detector body, and all the grooves are located on the same straight line.

If there is an error, it needs to be corrected and adjusted. Of course, the judgment program can also be set inside the display device 8 to prompt the calibration process and data. Note: During the detection process, please make sure that the span ruler is completely fitted with the end measuring plate and fixed measuring block at the top of the calibrator body, otherwise it will affect the accuracy of the test results. When adjusting the position of the movable calibration component, be careful not to use excessive force to avoid damaging the calibrator. If it needs to be used for a long time, please clean and maintain the calibrator regularly to maintain its good performance.
