Abstract
The utility model discloses a smithwelding combination formula obtuse frog belongs to railway switch technical field, it by the stock rail, forge the fork heart, heart rail, group's rail, interval iron, bolt group, just fill up, locking side's pad constitutes, its structure does: heart rail is the track setting symmetrical relatively of two symmetries, is the angle after two heart rails make up 18 55'29 ", two heart rail front end intercepting length 120mm, the fork heart after will forging uses the flash welding connection to weld the basal orbit front end of heart rail, heart rail symmetry in overall structure sets up, the relative 286mm of two sets of heart rail point, and does the rail set up the angle is 161 for stock rail and group 4'31 ", the flangeway distance between group's rail and the stock rail is 47mm, fill up and install in the web of the rail of group's rail the side, and the bolt of bolt group passes the bolt -up of helping rail, stock rail, heart rail, interval iron, stock rail, group's rail, locking side's pad to be organized by the bolt in proper order.
Description
Technical field
This utility model is related to a kind of smithwelding combination type obtuse frog, belongs to railway switch technical field.
Background technology
At present, No. 3 double crossover track switches of China railways are the equipment using under rail yard hump, and current No. 3 intersections
Obtuse frog in crossover turnout all adopts potassium steel block cast pattern, and due to casting flaw and high manganese steel casting, it makes
Relatively low with the life-span, frequently change and will bring impact to train marshalling list.
Content of the invention
In order to overcome above-mentioned technical deficiency, this utility model provides a kind of smithwelding combination type obtuse frog, this forging
Welding combined obtuse frog adopts steel alloy material to manufacture, stock rail, heart rail, the fork heart, side rail, interval iron, high-strength bolt group, side
Pad, anti-loose measure pad composition, wherein help the use of rail, effectively wheel are played with protective action and increased stock rail intensity, make rut
Fork improves resisting fatigue and does polishing machine, extends service life.
This utility model solves its technical barrier and be the technical scheme is that a kind of smithwelding combination type obtuse frog, rut
The stock rail of fork, fork heart heart rail are added using steel alloy rail high intensity, after heat treatment improving resisting fatigue and anti-wear performance
Work manufactures；It is made up of stock rail, the forging fork heart, heart rail, side rail, interval iron, bolt group, side's pad, anti-loose measure pad；Its structure
For: heart rail is two symmetrical track relative symmetry settings, and the angle after two heart rail combinations is 18 ° 55 ' 29 ", two heart rails
Front end intercepted length 120mm, the fork heart after forging is welded to the basal orbit front end of heart rail using flash welding connection；The described heart
Rail is symmetrical arranged in overall structure, two groups of heart rail rail point relative distances 286mm, and stock rail and side rail setting angle are 161 ° 4 '
31 ", the flangeway distance between side rail and stock rail is 47mm；It is arranged in the web of the rail of side rail in symmetrical centre prescription pad, spiral shell
The screw bolt passes of bolt group help rail, stock rail, heart rail, interval iron, stock rail, side rail, anti-loose measure pad by the bolt of bolt group
Fastening；Between side rail, stock rail, the forging fork heart, stock rail, the side each rail of rail, interval iron is installed.
The beneficial effects of the utility model are: the accessory of stock rail, fork heart heart rail and wheel close contact, using high intensity
Alloy rail thermally treated processing and manufacturing, improve the overall resisting fatigue of railway frog and wear resistance, extend service life；
The use of side rail increases the safety of railway frog.

Bolt group, side's pad, anti-loose measure pad assembling composition；As shown in Figure 1-Figure 3, its structure is: heart rail 3 is that two symmetrical tracks are relatively right
Claim setting, the angle after two heart rail combinations is 18 ° 55 ' 29 ", two heart rail 3 front end intercepted length 120mm, after forging
The fork heart is welded to the basal orbit front end of heart rail using flash welding connection；Described heart rail 3 is symmetrical arranged in overall structure, two groups
Heart rail 3 rail point relative distance 286mm, stock rail 1 and side rail 4 setting angle are 161 ° 4 ' 31 ", between side rail 4 and stock rail 1
Flangeway distance is 47mm；It is arranged in the web of the rail of side rail 4 in symmetrical centre prescription pad 7, the screw bolt passes side of bolt group 6
Rail 4, stock rail 1, heart rail 3, interval iron 5, stock rail 1, side rail 4, anti-loose measure pad 8 are fastened by the bolt of bolt group 6；Side rail 4, base
Between this rail 1, the forging fork heart 2, stock rail 1, the side each rail of rail 4, interval iron 5 is installed.
