Background
The turnout is one of key railway engineering equipment, and can realize the crossing or turning operation of a train. The switch is divided into switch area, connecting part and frog area, the key parts of switch area are point rail and basic rail, and the key parts of frog area are point rail and wing rail. When a train passes through a turnout zone, the wheel load needs to be transited between a switch rail/stock rail and a point rail/wing rail, and the process causes the transfer of wheel rail contact points, so that the rolling circle radiuses of two sides of a wheel set are inconsistent, or the height of the mass center of the wheel set is changed. When the rolling circle radiuses on the two sides of the wheel pair are different, the wheel pair deviates from the center of the track and deviates to one side to form transverse irregularity;
when the height of the mass center of the wheel pair changes, under the action of inertia, the wheel rail forms large-amplitude impact load to form vertical irregularity. The transverse and vertical irregularity is inherent irregularity of a turnout area, so that the dynamic action of a wheel rail of the turnout area is obviously larger than that of an interval line, the frog area is most obvious, and the wheel rail impact of the frog reaches 2-3 times of the nominal wheel load in serious conditions.
In order to reduce the wheel-rail impact load of a turnout switching area as much as possible, a certain number of wing rail lifting values are usually set when the turnout structure is designed, and the purpose is to reduce the variation amplitude of the wheel set mass center height as much as possible and reduce the wheel-rail impact load. In the actual operation process, the wing rail is seriously abraded, the height of the wing rail is severely changed, but no special wing rail lifting value measuring equipment is provided at home at present, and great difficulty is brought to field maintenance. Therefore, the invention provides special equipment for measuring the lifting value of the frog wing rail on the basis of analyzing the structural characteristics of the frog, and aims to realize simplicity and high efficiency.
At present, there are existing devices for measuring relative height difference between a frog region point rail and a wing rail, such as miniprox, vernier caliper and the like. miniProf can measure the rail head profile of the steel rail, obtain the longitudinal and horizontal coordinate values of the center rail and the wing rail, and calculate the relative height difference between the center rail and the wing rail according to the coordinate values, thereby obtaining the center rail reduction value through calculation. The vernier caliper is installed on a horizontal cross beam, the cross beam is placed on the wing rails on two sides, and the vernier caliper is vertically moved to be in contact with the top surface of the point rail, so that the relative height difference between the point rail and the wing rails is obtained.
