Technical Field
The invention relates to the technical field of turnouts, in particular to a device for quickly measuring the bending vector of turnout steel rail pieces.
Background
The angle formed by the switch point, called the frog angle, is large and small. The switch number (N) represents the number of switch.
The main dimensions of the individual portions of the switch are usually expressed in the value of the cotangent of the frog angle (α), i.e., N ═ cot α ═ FE/AE. Switch angle of No. 9
Obviously, the smaller the frog angle alpha, the larger the value of N, the larger the radius of the switch curve, the smoother the side track of the train passes through the turnout, and the higher the allowable turnout speed. It is advantageous for train operation to use large switches. However, things always have two sides, and the larger the number of turnout points is, the longer the turnout points are, the higher the manufacturing cost is naturally, and the more occupied land is. Therefore, what number of switches should be used is not an overview, and is not intended to be used according to local conditions and line-to-line conditions. The main railway line is mainly provided with switches of 9, 12 and 18 types.
The frog angle of the turnout steel rail piece is also measured by bending vector, the ratio (S/L) of the calculated rise S of the vector to the calculated span L or the ratio of the net rise to the net span, also called the vector, is smaller, the bending vector is larger, the vector is larger, and the stability of the train passing through the turnout steel rail is higher.

However, the defect that only the V-shaped steel rail can be measured exists, because the reference ruler and the movable ruler are straight rulers, the curved steel rail cannot be well attached and fixed with the steel rail when being measured, and the measurement is not accurate when the curved steel rail is measured; and because the bottom of the steel rail is often a gravel base layer, the surface of the gravel base layer is uneven, and when the reference ruler and the movable ruler are attached to one side of the steel rail, the bottom of the reference ruler and the bottom of the steel rail cannot be kept in the same horizontal state well, so that the measurement accuracy is influenced.
