Problems solved by technology

This kind of turnout point rail inserts bainitic point from the beginning of the point rail to the 20-40mm section, which solves the problem of high cost of using bainitic steel for the whole rail, and only needs to replace the bainite point rail during repair. It has the characteristics of simple process, stable performance, low manufacturing cost, and repeated reuse of resources. It can increase the service life of the switch rail and reduce the operating cost of the railway. It has good economic benefits and practical value. However, this kind of switch point rail The service life is still very short, frequent maintenance and replacement

Abstract

The invention discloses a stock rail and switch rail railhead configuration form, and relates to the technical field of rail components. A stock rail and a switch rail are included, the stock rail comprises a railhead and a rail chair, and the railhead is arranged above the rail chair; the width of the railhead is 10-20 mm, a working side in contact connection with a switch rail railhead on the switch rail is arranged on the railhead, and the inclination degree of the contact surface of the working side and the switch rail railhead is 1 / 5-1 / 3; extra 2-5 mm machining treatment is conducted on the working side inward, the extra machining portion is divided into two sections, the length of the first section is 50-200 mm, and the length of the second section is greater than 500 mm; the inclination degree is 1 / 1000-1 / 300, and the switch rail railhead is 23 mm lower than the outer edge of a wheel. According to the stock rail and switch rail railhead configuration form and the characteristicof the tangent line type switch rail, under the circumstance of not changing the impact angle, the stock rail railhead portion closely fitting the switch rail is extra machined, the width of the switch rail railhead is increased, and therefore the strength of the switch rail is increased.

Description

technical field [0001] The invention relates to the technical field of track components, in particular to a structure form of a basic rail and a switch rail head. Background technique: [0002] A point switch is a conversion device for a turnout, and it is a device that guides the wheel rim to enter the designated track smoothly; the point switch is composed of two basic rails, two tip rails, other connecting parts and switch conversion equipment. The point switch switch rails can be divided into three categories according to the plane form: tangential switch rails, spaced switch switch rails and separated switch switch rails; , as if entering a curved track, the formation is relatively stable; the impact angle of the wheel on the tip rail is small; the weakened part of the tip of the tip rail is too long, the width of the tip rail head is small, and the tip rail is not wear-resistant when subjected to lateral impact. The impact angles of the separation-type switch rail and...
