Embodiment Construction

[0013] The alloy steel reinforced frog structure of the present invention is as figure 1 As shown, it is composed of combined core rail 1 and wing rail. The combined core rail 1 is composed of left connecting core rail, right connecting core rail and core rail. The core rail is located at the end of the combined core rail. The combined core rail 1 and the wing rail are spaced The iron 10 is connected with the bolt 12, and the wing rail includes the left wing rail 3 and the right wing rail 2 such as image 3 As shown, where a is 20mm, the left wing rail splint 7 is installed between the left wing rail 3 and the core rail, and the left panel 5 is embedded inside the left wing rail 3; the right wing rail splint 6 is installed between the right wing rail 2 and the core rail, and the right wing rail 2 The inner side is embedded with the right panel 4, and the left panel 4, the right panel 5 and the left wing rail 3 and the right wing rail 2 are bonded by adhesive, and the left pane...

Abstract

An alloy steel reinforcement frog is composed of a point rail, a connection point rail and wing rails, wherein one end of the point rail is connected with the connection point rail, the wing rails include a left wing rail and a right wing rail, a left insertion plate is inserted into the inner side of the left wing rail, and a right insertion plate is inserted into the inner side of the right wing rail. According to the alloy steel reinforcement frog, high-strength wear-resistant alloy steel insertion plates are inserted into the wing rails in a cutting edge bending method. When steel plates are machined, chamfered edges are only manufactured on working edges of the point rail before 40mm of the section, R13mm arcs of a steel rail are eliminated, and R13mm frog center arcs are reduced. Therefore, wheels roll through the highest abrasion position of the frog, contact stress of the frog is reduced, strength of materials is improved, conquassation of the wing rails is reduced in the process of using the alloy steel frog, and service life of the frog is prolonged.

Description

technical field [0001] The invention relates to the field of railway equipment and equipment, in particular to a frog used for railway track bifurcations. Background technique [0002] Alloy steel turnouts are generally laid on turnouts with a vehicle speed of no more than 250km / h spanning super-long seamless and general lines. In recent years, with the increase in the number of uses, increasing the service life, that is, increasing the tonnage of currency, is an urgent problem that needs to be solved before us. In order to reduce railway operating costs and improve economic benefits, it is planned to improve the process of alloy steel frogs so that they can exceed the service life of ordinary alloy steel frogs. If used properly, it may reach a price that is twice as expensive as alloy steel frogs. Full bainitic steel frog life. [0003] The service life of alloy steel frogs currently used generally does not exceed 200 million tons. The forged fork center is made of wear-r...
