X-shaped fast positioning device for railway rail center position measurement
The invention relates to an X-shaped fast positioning device for railway rail center position measurement. For the steel rail three-dimensional space posture observation in the prior art, a rail geometrical state measuring instrument needs to be put in a steel rail measuring position for positioning, and the collecting efficiency is lower. The X-shaped fast positioning device comprises a lower layer X arm and an upper layer X arm provided with center open holes, wherein the two arms are respectively straight arms, the upper and lower center open holes are aligned, crossed and combined for forming an X shape; a locking screw nut is arranged in each center open hole, a prism rod is inserted in each locking screw nut, the bottom end of each prism rod is a concave spherical surface, a semi-cylinder is arranged under the concave spherical surface, and is positioned on the surface of the steel rail, the bottom surface of the semi-cylinder is a flat plane, and the top surface of the semi-cylinder is a spherical surface; the end part of the lower layer X arm and the end part of the upper layer X arm are respectively provided with downwards steel rail clamp hook heads which are positioned at the two sides of the steel rail; fixing buckles are arranged between the same ends of the lower layer X arm and the upper layer X arm positioned at the opposite sides of the steel rail. The X-shaped fast positioning device has the advantages that the fast positioning of the high-speed railway rail center position can be realized through a full station instrument, the collecting efficiency is improved, the measurement is simple, convenient and flexible, and the measuring precision is also greatly improved.
