Background
The automobile loading brake test bench is used for testing the braking performance and axle (wheel) weight of the wheels of the multi-axle and parallel axle vehicle. The height difference of the main roller and the auxiliary roller is one of verification items, and is mainly used for determining the ground clearance of a bus on the auxiliary roller. At present, a metering technical mechanism mainly adopts a height caliper to measure the height difference of a main roller and an auxiliary roller according to the verification procedure of JJG 1160-2019 'automobile loading brake inspection bench'. During measurement, the height caliper base is placed on a frame of the automobile loading braking inspection bench, the ground clearance heights of the main roller and the auxiliary roller are respectively measured through the measuring surface of the scriber, and then the ground clearance height difference of the main roller and the auxiliary roller is calculated. The vertical plane of the frame edge parallel to the main/auxiliary roller and the vertical plane of the main/auxiliary roller are far away from each other and exceed the measuring range of the measuring arm of the height caliper with the scriber, so the height caliper needs to customize and lengthen the measuring arm to finish measurement. In order to ensure measurement accuracy, the customized extender arm scriber can only meet single-point measurement, namely, the position of the base on the frame needs to be replaced when different positions are measured. However, the frame is affected by logistics transportation, construction and installation and the like, and the working surface of the frame can not be guaranteed to be always on the same horizontal plane; in addition, in order to measure the indication value stably, the base occupation area is relatively large, and the base can not be completely placed on the working surface of the frame, so that the reference surface for measuring the ground clearance of the main roller and the auxiliary roller is not on the same plane, and the measurement error is large. Therefore, there is a great limitation in the way of measuring the height difference between the main roller and the auxiliary roller by adopting the height caliper, and it is necessary to design a measuring device for the height difference between the main roller and the auxiliary roller to solve the above technical problems.
Disclosure of utility model
In order to solve the defect that a measuring mechanism laboratory adopts a height caliper to measure the height difference of a main roller and an auxiliary roller, the utility model provides a measuring device for the height difference of the main roller and the auxiliary roller.
