Problems solved by technology
The traditional method is to use mechanical measurement, such as vernier calipers, which can only reflect the parameters of a single track slab during detection, and cannot realize the detection of parameters such as flatness, straightness, and torsion of the bearing surface of the entire track slab.

Embodiment Construction
[0011] Detection frame of the present invention such as figure 1 , figure 2 As shown, the left detection board and the right detection board are connected by connecting rod 7, and the left detection board is connected by screws and nuts to form a rectangular structure by the left bottom board 10, two long vertical boards 8, and two short vertical boards 9, and the right detection board is formed by The right bottom plate 11, two long vertical boards 8, and two short vertical boards 9 are connected by screws and nuts to form a rectangular structure. The above two long vertical boards 8 and two short vertical boards 9 are divided into front long vertical boards according to their positions. , Rear long riser, outer short riser, inner short riser. The inclination angles of the above-mentioned outside short riser and the inside short riser are respectively the same as the inclination angles of the outside bevel 20 and the inside bevel 21 of the rail platform, and the inclination...

The invention aims to provide a detection frame capable of detecting a plurality of geometric parameters of a track slab, in particular a track slab detection frame, wherein a left detection plate and a right detection plate are connected by a connecting rod and provided with 6 dial gauges; the bottom of a left bottom plate is provided with a first universal ball seat and a second universal ball seat; a right bottom plate is provided with a third universal ball seat; and a contact point of the sixth dial gauge and a rail bearing surface and three contact points of the three universal ball seats and the rail bearing surface form a rectangle. In the invention, data of the dial gauges are initialized to zero on only a pair of standard rail bearing stations, then the dial gauges are installedon the rail bearing station of a track slab to be detected, and the data variation of the dial gauges is compared with a theoretical value, thus the geometric parameters, such as large and small jaw distance of the track slab, torsion resistance of a rail cant and the rail bearing surface and the like are obtained by calculation.
Description
technical field [0001] The invention relates to a detection device and a detection method for detecting whether the geometric positional relationship of the track plate of the high-speed railway meets the design requirements during the construction of the high-speed railway. Background technique [0002] When building a new railway, especially when inspecting the quality of the track slab, it is necessary to control the quality of the track slab within the allowable tolerance range of the design value given by the design institute. The traditional method is to use mechanical measurement, such as vernier calipers, which can only reflect the parameters of a single track slab during detection, and cannot realize the detection of parameters such as flatness, straightness, and torsion of the bearing surface of the entire track slab. . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a detection frame capable of detect...
