Abstract

The utility model relates to a fixed frog, which is a guide frog used on a railway. The utility model comprises a basis straight rail 1, a basis arc bend rail 3, an arc tongue 2, a straight tongue 4 and a frog center 11. The arc tongue 2 and the straight tongue 4 are respectively and fixedly installed on rail bearings of the inner sides of the basis straight rail and the basis arc bend rail. Wheel edge grooves of a wheel 7 are respectively arranged between the end part of the arc tongue and the basis straight rail and between the straight tongue and the basis arc bend rail. A train of the outer side of the wheel 7 or the bottom of a car 9 is provided with a composition part of a swinging wheel shaft 10 the lower end of which is provided with a rotary wheel 6 by a control device. The utility model makes the train switched accurate, quick, safe and stable.

Description

Fixed frog

The utility model relates to the guiding track switch of using on a kind of railroad track.

At present, track switch commonly used mainly contains two kinds of forms on the railroad track, and a kind of is Artificial Control track switch; Another kind is electronic control track switch.No matter be Artificial Control track switch, still electronic control track switch, as shown in Figure 1, all curved 3 by basic straight rail 1, basic arc, straight tongue 4, arc tongue 2, controller 5 and the fork heart 11 etc. are formed.The guiding of railroad track is to rely on controller 5 to drive straight tongue 4 or 2 translations of arc tongue, and finish the inboard inboard or basic straight rail 1 that makes it to abut against basic arc-shaped curved track 3.All there is the slow shortcoming of action in this road fork that uses now no matter be which kind of mode is controlled its translation, the effect of clutch guiding fast between the vehicle in being difficult to realize running at high speed.If the action of road fork is untimely, trouble accident or other fault might take place to squeeze, bring very big hidden danger will for the property of country and the people's life security.

The purpose of this utility model is to provide a kind of train lane change accurate, rapid, safe Fixed frog.

The utility model is to realize like this, it comprises the basic straight rail that constitutes traditional railway track switch, basic arc-shaped curved track, straight tongue, the arc tongue and the fork heart, its technical essential is: the arc tongue is fixedly mounted on the sleeper of basic straight rail inboard, and between arc tongue end and stock rail, be provided with the flangeway of wheel, straight tongue is fixedly mounted on the inboard of basic arc-shaped curved track, and between straight tongue end and basic arc-shaped curved track, be provided with the flangeway of wheel, a swing wheel shaft is installed through control device in train or bottom, compartment at lateral wheel, in the outer end of this swing wheel shaft a runner is installed and constitutes.

The application principle of this Fixed frog is: when train during along straight tongue or the lane change of arc tongue, because straight sharp road and basic arc-shaped curved track or arc tongue be with substantially directly the slit between the rail is less, wheel then can automatically be gone through transition reposefully.When train during against straight tongue or the lane change of arc tongue, with the train craspedodrome is example, before train enters the fork road, the control device of train and lower end, compartment makes axially upset down of wobble wheel under the control of train driver, the runner of swing wheel shaft lower end is leaned against the outside of basic straight rail, the wheel rim of wheel is pulled to basic straight rail inboard, up to the side of wheel rim and rail substantially directly till contacting.At this moment, when wheel passes through the arc tongue, pass through the flangeway of the car edge of wheel between arc tongue and basic straight rail.The car edge of opposite side wheel then falls back on straight tongue inboard, progressively carries out the transition on the straight tongue from basic arc-shaped curved track, finishes the craspedodrome of train.After finishing train and keeping straight on, make on the swing wheel shaft with control device turn over, resetting gets final product.

Because this pass has become fixedly road fork with novel moving road fork with track, train no longer is subjected to the influence of fork motion when pitching by the road, the multiple row train can be continuously by this road fork like this, it can improve the handling capacity of train widely, when train passes through, wheel progressively transition on another track from the track, guarantee train operation steadily, safety.The transition of train becomes the train operator according to signal controlling by road fork industry control system, makes the lane change of train more accurate.

Fig. 1 is existing railway switch and control principle figure;

Fig. 2 is said Fixed frog of the utility model and wheel operation schematic diagram;

Fig. 3 is the structure principle chart of the said transition controlling organization of installing in train or lower end, compartment of the utility model.

Below in conjunction with accompanying drawing the utility model is described in detail.

As shown in Figure 2, basic straight rail 1 in the element of this track switch, basic arc-shaped curved track 3, arc tongue 2, straight tongue 4 and the fork heart 11 are basic identical with existing track switch shown in Figure 1, they are different is that arc tongue 2 is fixedly mounted on the sleeper of basic straight rail inboard, and arc tongue 2 leading sections with substantially directly leave the flangeway that can allow the wheel rim of wheel 7 pass through between the rail.Straight tongue 4 then is fixedly mounted on the sleeper of basic arc-shaped curved track 3 inboards, and the leading section of straight tongue 4 with also be provided with the flangeway that can allow the wheel rim of wheel 7 pass through substantially between the arc-shaped curved track 3.In order to control train by track switch, wheel 7 outsides of train that adapts therewith or 9 lower ends, compartment are equipped with a swing wheel shaft 10 through a control device 8, a runner 6 is installed in the lower end of this wheel shaft 10 constitutes.Here said control device 8 can be a hydraulic pressure tilt cylinder, through the swing of hydraulic pressure tilt cylinder, drives wheel shaft 10 swings, and the direction of train is controlled in the outside that makes runner 6 lean against stock rail.This control device 8 can also be to pass through crank-link mechanism by hydraulic cylinder, makes the swing of wheel shaft 10.

It can also be seen that by Fig. 2 when A travelled, need not control, and then can become rail automatically by train from B or C for train, promptly progressively forward on the stock rail by tongue, and train from A when B or the C transition, then need the train operator to control.The train of representing with Fig. 2 is that example is carried out following explanation from A to the C direction running.When wheel 7 drove to the position of I, the effect of process runner 6 made the wheel rim side that is pressed in the wheel 7 on the basic arc-shaped curved track 3 lean against the medial surface of basic arc-shaped curved track 3.When wheel 7 ran to the position of II, wheel began transition; When wheel 7 ran to the position of III, the wheel that is pressed on the basic straight rail 1 progressively forwarded on the arc tongue 2; When wheel 7 ran to the position of IV, wheel 7 transitions finished.Have only after the permutation train passes through track switch, whole runners 6 are lifted.
