Problems solved by technology
Due to the relatively small height of the F rail installation seat plate, it will affect the normal induction sleeper signal of the speed sensor, and will generate a long-term constant or short-term high-frequency pulse speed acquisition signal, which will affect the speed processing and output of the speed measurement system, and then output abnormal signal
In addition, when the distance between the two rails is less than 600mm, the timing error of the two speed sensors will occur or the pulse will be sensed at the same time, and the calculated speed signal will be wrong.

Abstract
The invention relates to a turnout beam structure adapting to speed measurement of a magnetic suspension running vehicle. The turnout beam structure not only can enable a speed sensor of the magneticsuspension running vehicle to accurately and effectively realize speed measurement positioning of the magnetic suspension running vehicle by detecting the number of sleepers, but also can effectivelysolve the interference problem in the speed measurement signal acquisition process, and also can effectively avoid the natural vibration frequency of the magnetic suspension running vehicle. 1) A turnout beam is formed by welding a bottom plate, a middle high web plate, two side short web plates, a middle cover plate and two side cover plates into a box body shape with three continuous cavities, the width a of the turnout beam is determined according to the limit requirements of the magnetic suspension vehicle; 2) each sleeper consists of an upper cover plate, two side web plates and a stiffening plate to form two box bodies separated by the stiffening plate in the middle, and an adjusting plate is located on the upper cover plate; 3) the sleepers are symmetrically arranged on the two sides of the turnout beam at the intervals of 600mm-1200mm according to requirements of the speed measurement sensor, and are fixed through welding or bolt connection modes.
