Abstract

The utility model relates to a track frog in the railway track, it is equipped with a pivot to lie in the crossing department of two wing rail central lines on the its characterized in that backing plate, a tie rail is equipped with in the pivot, the both ends of pivot, frog point rail point end and the one end that two wing rails are facing to frog point rail are with the coaxial face of cylinder of pivot axis, the tie rail can rotate along with the pivot and link up two wing rails and frog point rail respectively, and by dog on the tie rail and the spout location on the bottom plate, the "harmful space" of frog has been eliminated, wheel outer fringe collision injury caused by "harmful space" has been overcome, the vibration, the big and a great deal of problems such as greatly reduced speed of a motor vehicle when the train passes through the frog of noise.

Description

A kind of rail frog

The utility model relates to a kind of rail frog in a kind of railroad track.

At present the railway frog in the railroad track is made up of wing rail, central body of frog and backing plate etc., and bigger space is arranged between central body of frog and two wing rails, and the throat of frog place that forms the most nearby of actual point of frog to two wing rail working edge has formed one " idle space " like this.So when train passed through railway frog wheel warp " idle space ", the collision of wheel and wing rail or central body of frog was more serious, it is higher that felly face subject to damage and vibration reach noise more greatly, need slow down when train is by railway frog simultaneously.

The purpose of this utility model is to provide the rail frog of a kind of elimination " idle space ".

The purpose of this utility model is realized by following technical scheme:

The utility model is by two wing rails 1,10, central body of frog 5, and backing plate 9 is formed, wing rail 1,10 and central body of frog 5, be installed on the backing plate 9, the tip of central body of frog 5 is a face of cylinder, two wing rails 1,10 is one section straight rail, on backing plate 9, be positioned at both wings rail 1,10 center line intersection is provided with a rotating shaft 4, one section connection rail 3 is housed in the rotating shaft 4, have arc chute 11 on the backing plate 9, the both ends of the surface 11a of chute 11,11b respectively with two wing rails 1,110 is parallel, being fixedly arranged on the block 8 that connects rail 3 bottoms stretches in the chute 11, and the two sides 8a of block 8,8b is parallel with the both sides that connect rail 3, link stopper 8 two sides 8a, 8b to the distance on connection rail 3 bases of homonymy with it respectively with relative chute both ends of the surface 11a, 11b to two wing rail 1, the distance of 10 flanges of rail outside equates.Two wing rails 1,10 are the dead in line of coaxial circles cylinder and axis and rotating shaft 4 facing to an end of central body of frog 5, the two ends that connect rail 3 and the tip of central body of frog 5.The length that connects rail 3 is slightly less than the distance of two

wing rails

1,10 and 5 of central body of frog, rotates mutual required gauge play when being connected wing rail 1,10 and central body of frog 5 respectively to guarantee to connect rail 3 with rotating shaft 4.

Establish an electric point machine at this railway frog place with drive connection rail 3, and connect the tongue interlock that needs when rail 3 rotates with rotating shaft 4 with another goat drive, to guarantee the safety of driving.Connect rail 3 and can be connected central body of frog 5 and two wing rails 1,10 respectively, and, make to be connected accurately, can eliminate " idle space " of railway frog like this, make train smooth ground pass through railway frog by arc chute 11 and link stopper 8 location with changeing 4 rotations.

The utility model is simple in structure, is connected accurately and reliably, and basic collisionless when train passes through, and vibrate little noise floor, the fork speed excessively of more original railway frog train can improve greatly simultaneously.

Description of drawings:

Fig. 1 is an example structure figure of the present utility model;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the upward view of Fig. 1.

Below in conjunction with embodiment the utility model is further specified.

This railway frog can be cast into a whole railway frog by potassium steel, and for guaranteeing the fixing of rotating shaft 4 and connection that is connected rail 3 and block 8, the web of the rail of connection rail 3 is thickeied.Have axis hole 12 on backing plate 9, a lining 6 is housed in the axis hole 12, rotating shaft 4 is rotary with retaining ring for shaft shoulder 7 after passing lining 6, rotating shaft 4 be connected between rail 3 for being threaded.Block 8 is fixed on by screw 2 and connects on the rail 3.One end of the tip of central body of frog 5, two wing rail rails 1,10 and connect rail two ends the face of cylinder axis coaxle and with the dead in line of rotating shaft 4, so that mutual gauge play is less when connecting rail 3 and being connected wing rail 1,10 and central body of frog 5 respectively, and can rotate freely.The employing on the cohesive end face of cylinder has simultaneously also slowed down collision and the vibration when wheel passes through.The utility model adopts a rotating connection rail 3 to be engaged on 5 of wing rail 1,10 and central body of frog, eliminated idle space, thus the many unfavorable factors that caused because of idle space when having avoided train by railway frog.
