Embodiment Construction

[0013] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0014] see figure 1 , The present invention provides a technical solution: a staggered limb elastically bendable core rail frog, including a first wing rail 1, a second wing rail 2, a long core rail 3 and a short core rail 4.

[0015] The first wing rail 1 and the second wing rail 2 are arranged symmetrically or asymmetrically, and a long core rail 3 and a short core rail 4 are arranged between the first wing rail 1 and the second wing rail 2, and the long core rail 3 One end is fixedly connected to one end of the short core rail 4.

[0016] In this embodiment, the first wing rail 1 and the secon...

Abstract

The invention belongs to the technical field of railway turnouts, and provides a staggered double-limb elastic bendable point rail frog including a first wing rail, a second wing rail, a long point rail and a short point rail. The first wing rail and the second wing rail are arranged symmetrically or asymmetrically, and the long point rail and the short point rail are arranged between the first wing rail and the second wing rail, and one end of the long point rail is fixedly connected with one end of the short point rail. Since the first wing rail, the second wing rail and the long and short point rails arranged between the two wing rails are arranged, and the long point rail and the short point rail are of an integrated structure, by means of mutual staggering of the long and short pointrails in the conversion process, reliable work of the double-limb elastic bendable structure is achieved, harmful space and an inclined joint are eliminated, meanwhile, the turnout line shape is wellcontrolled, structural design is simplified, train stability is improved, running conditions are improved, vibration noise produced by wheel track impact is reduced, and environmental protection requirements are met.

Description

technical field [0001] The invention belongs to the technical field of railway turnouts, in particular to a staggered double-leg elastic bendable center rail frog. Background technique [0002] The turnout is the key equipment of the urban rail transit, and it is also the weak link of the track, which directly affects the smooth operation of the train, the comfort of passengers and the vibration of the surrounding environment. The frog is an important part of the turnout, which is divided into fixed frogs and movable core rails. There are two types of frogs. Urban rail transit turnouts mainly use fixed frogs, which have a simple structure, but the trajectory is discontinuous, there are harmful spaces, and the structure vibrates greatly; the track of the movable center frog is continuous, smooth, and can eliminate harmful spaces, but the structure is complex Among them, there is an oblique joint in the elastically bendable and movable frog with one limb, which is not conduci...
