Embodiment 1

[0023] Such as Figure 1-3 As shown, the present invention provides an alloy steel fork center of an I-rail asymmetrically welded three-opening turnout, including a fork center block 1, and a fork center rim groove is opened on the fork center block 1, and the fork center track It includes straight rim groove 2, curved rim groove 1 3 and curved rim groove 2 4, the three-way turnout is an asymmetric structure, and the curved rim groove 2 4 is located at the front end of the curved rim groove 1 3 The straight rim groove 2 is on the same side, the curved rim groove 2 4 intersects with the curved rim groove 1 3 at the front of the fork block 1 to form the first fork center part, and the curved rim groove A 3 intersects with the straight rim groove 2 to form a second fork at the rear of the fork block 1 . This structure can be applied to the fork center of various asymmetric three-way turnouts. It has good integrity, and the number of components is only one fork center block. It h...

Abstract

The invention discloses an alloy steel fork center of an asymmetrically welded three-throw turnout of an I-shaped rail. The alloy steel fork center comprises a fork center block. A fork center flangeway is formed in the fork center. A fork center rail comprises a linear flangeway, a curved flangeway I and a curved flangeway II. The three-throw turnout is of an asymmetrical structure. The front ends of the curved flangeway I and the curved flangeway II are located on the same edge of the linear flangeway, the curved flangeway I and the curved flangeway II are intersected to the front part of the fork center part to form a first fork center part, and the curved flangeway I and the linear flangeway are intersected to the back part of the fork center part to form a second fork center part. The fork center of the three-throw turnout can be arranged flexibly according to the current situation. The alloy steel fork center has the advantages of being good in wear resistance, long in service life, high in processing precision and the like, and meanwhile, a high cost of developing a casting mold is saved.

Description

technical field [0001] The invention belongs to the field of rails, and in particular relates to an alloy steel fork center of an I-rail asymmetrically welded three-opening turnout. Background technique [0002] In the track field, a turnout is a connecting device that allows vehicles to transfer from one track to another, and is usually laid in large numbers in the parking lots of vehicles and depots. The three-way turnout is a relatively complex structure of the turnout, which has the unique characteristic of being able to open in three directions. When arranging turnouts in marshalling yards and freight yards, due to terrain constraints, there is not enough space for laying multiple sets of single-opening turnouts to meet the demand. At this time, the advantages of three-way turnouts are highlighted. At present, most marshalling yards and freight yards in China are laid with symmetrical three-way turnouts. The fork center is cast in high manganese steel. The layout is si...
