Specific embodiment
To be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, below with reference to
The drawings and specific embodiments, the present invention is further explained.
Embodiment
As shown in Figures 1 to 5, a kind of combination high manganese steel frog, including block cast plate 1, the block cast plate 1 are equipped with frog flangeway 2,
The frog flangeway 2 includes singly opening frog flangeway and obtuse frog slot 5, and the frog flangeway of singly opening includes that I type list opens frog flangeway 3 and II type
Frog flangeway 4 is singly opened, the I type list opens frog flangeway 3 and the II type list opens the obtuse angle that frog flangeway 4 is located at the obtuse frog slot 5
Side, the I type list opens the acute ends that frog flangeway 3 is located at the obtuse frog slot 5, and the II type list opens frog flangeway 4
Positioned at another acute ends of the obtuse frog slot 5；The I type list opens the straight inguinal canal of frog flangeway 3 and the II type list opens rut
The straight inguinal canal of fork pockets 4 is connected and collinearly, and the I type list opens the side inguinal canal rail corresponding with the obtuse frog slot 5 of frog flangeway 3
Slot is connected and collinearly, the side inguinal canal track slot corresponding with the obtuse frog slot 5 that the II type list opens frog flangeway 4 be connected and
Collinearly.
The I type list opens the straight inguinal canal of frog flangeway 3 and the II type list identical, the institute that opens the groove width of straight inguinal canal of frog flangeway 4
State I type list open frog flangeway 3 side inguinal canal it is identical as the groove width of the corresponding track slot of the obtuse frog slot 5, the II type list opens rut
The side inguinal canal of fork pockets 4 is identical as the groove width of the corresponding track slot of the obtuse frog slot 5.
The block cast plate 1 is no bottom shell body, and vertical muscle 6 is equipped in the shell and transverse bar 7, the transverse bar 7 are arranged at intervals on
The bottom of the block cast plate 1, the top of the vertical muscle 6 are fixedly connected on the top of the block cast plate 1, the bottom end of the vertical muscle 6
It is fixedly connected with the transverse bar 7；The slot bottom of the frog flangeway 2 is fixedly connected with the vertical muscle 6.
The vertical muscle 6 for being connected to 2 slot bottom of frog flangeway is the riser for extending along corresponding track slot direction and being formed.
The block cast plate 1 is fixedly mounted on sleeper 9 by railway spike bolt 8.
In the present embodiment, the frog flangeway 2 is made into integration with the block cast plate 1；The block cast plate is equipped with for subtracting
The wing plate of small idle space.
The course of work and principle: in city rail, due to landform and primitive architecture, some, which need to be arranged, is handed over
The region of fork branch-cut bridge can not but arrange double crossover；And for small spacing double crossover, railway frog is singly opened due to potassium steel
Inconvenience is spliced and combined with the obtuse frog of potassium steel, therefore, it is difficult to be combined into the small spacing intersection of potassium steel for being suitable for above-mentioned environment
Branch-cut bridge；High manganese steel frog of the invention has skipped the splicing for singly opening railway frog and obtuse frog by the way of monoblock cast, can root
According to landform, adaptation to local conditions directly produces a complete whole branch-cut bridge railway frog.
First according to design of land double crossover, then according to the branch-cut bridge modeling of design, to produce sand mold, so
Melted metallic solution is cast into sand mold afterwards, takes out finished product after cooling.
Described on base, existing double crossover is to be spliced and combined by multiple railway frogs, however work as in city rail mostly
In, due to landform and primitive architecture, some regions for needing to be arranged double crossover can not but arrange that big spacing intersection is crossed
Line can only arrange small spacing double crossover；And in small spacing double crossover, due to the poor toughness of potassium steel, potassium steel list is opened
Railway frog can not be spliced and combined with potassium steel obtuse frog, and the potassium steel double crossover for the small spacing that cannot be produced can only use
Steel alloy rail is spliced；However the intensity of steel alloy and wearability are not so good as potassium steel, rail abrasion is larger.
The railway frog that block cast of the present invention goes out, replaces splicing and combining with monoblock cast, is not required to consider the splicing between railway frog
A complete small spacing double crossover is produced, vehicle is smoothly passed, route operational efficiency is increased；The present invention
It is provided with unified groove width in link position, the transition of guard rail open section difference groove width is avoided, improved the stationarity of vehicle；This
Muscle in length and breadth 7 is reasonably arranged in invention inside railway frog, while not influencing railway frog intensity and performance, is also reduced tired when casting
Difficulty reduces the probability of casting flaw appearance；When railway frog abrasion needs lower road, since the present invention is overall structure, only
A new railway frog is needed to change, so that replacement is more convenient, cost is compared to lower.
The above, preferable embodiment only of the invention, but scope of protection of the present invention is not limited thereto, and it is any
Those familiar with the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its invents
Design is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
