Detection device

Abstract

The invention discloses a detection device. The detection device comprises a detection plate (2) and base plates (1), wherein the bottom face of the detection plate (2) is a flat face horizontally arranged in a working state; the base plates (1) are arranged at the two ends of the detection plate (2) and used for positioning and being in contact with a bottom plate edge beam (4), and the bottom faces of the base plates (1) protrude out of the bottom face of the detection plate (2). According to the detection device, as the bottom face of the detection plate is the flat face, the flat face is a datum face, and the interval between the bottom face of the detection plate and the surface of a floor can be obtained; as the size of the thickness of a floor cloth layer and the size of the thickness of a honeycomb layer are fixed values, and the height that the bottom faces of the base plates protrude out of the bottom face of the detection plate is a fixed value, the thickness of a damping layer can be obtained. In this way, compared with damping layers at different positions of a vehicle body floor, the specific values of the thicknesses of the damping layers can be obtained with the method; the thicknesses of the damping layers are adjusted, and the leveling purpose of floor arrangement is effectively achieved.

Description

technical field [0001] The invention relates to the technical field of tooling equipment, in particular to a detection device. Background technique [0002] At present, the floor of urban rail vehicles mainly adopts a double-layer floor structure, and the double-layer floor is composed of a car body floor, a vibration-damping layer, a honeycomb layer and a floor cloth layer. [0003] In the double-layer floor, the thickness of the honeycomb layer and the floor cloth layer is a fixed value, so the leveling operation in the floor layout process can be achieved by adjusting the vibration-damping layer. However, because the processing precision of the vehicle body floor is not high, the surface flatness of the vehicle body floor is not high, so that the thickness of the damping layer corresponding to different vehicle body floor regions is different, and the problem of leveling the floor layout still exists. [0004] Therefore, how to solve the floor layout leveling problem is ...
