Description

Railway does not have split switch

The utility model relates to railroad track equipment.Concrete is a kind of no split switch.

We know: countless station that distributing on the railway line, all there are some circuits at each station.Train or shunt that to want the key equipment of turnover bar circuit freely be track switch is a tongue and track switch plays a major role.Because it is the residing position of tongue and its role be the particularity of its shape furthermore, therefore all very high to the technical requirements and the quality requirement of tongue.And tongue is rapid wear and easy break-down parts, and is very easily got involved and the generation fault by foreign matters such as ballasts in manipulation process and between the stock rail.There is train can strengthen through out-of-date rocking again from tongue.As seen, the not only important but also unavoidable problem of tongue is many.

Therefore, the utility model integrates important and vitals problem---tongue with regard to having cancelled this.The utility model adopts no split switch to realize the function of former track switch.This nothing split switch is fairly simple, fault rate is low, handle the more reliable more steady safety of train operation that makes.Belong to railway switch of new generation.

The purpose of this utility model is achieved in that

At the tongue root place of former track switch, together with stock rail " it is disconnected to impose uniformity without examining individual cases ".(this is popular saying) renames " switch track " (not changing substantially) as from " cut-out " towards the frog centre end; Tongue is removed towards the point of tongue from " cut-out ", again two stock rails are adjusted into standard gauge 1435mm, fix with cylinder lever connecting rod, ten meters are cried " moving rail " with interior renaming.(i.e. the meaning that can pull as former tongue) adds " moving rail root girth member " at the moving rail root at ten meters.Rail and sleeper is firm with fixed (outside this two meters rail joint must not be arranged with interior).To move the last point mechanism of rail connection and load onto annex and just become no split switch.Can pull the realization conversion and open the station track.

Now two key issues are illustrated respectively---location and fixing (locking) of moving rail (track switch):

One, the location of moving rail:

Every slide plate two ends of moving rail bottom all add " moving rail locator card " (being called for short locator card, down together), and moving rail can only be pulled between locator card back and forth.And the position that locator card sets is exactly the normal place of line clear straight line or side line.

Two, fixing (locking) of moving rail:

After moving rail was pulled certain card qualification that is positioned on one side, the fixing of moving rail this side just finished by locator card.The fixing of another side then finished by moving rail location latch fitting pusher (being called for short pusher, down together).Pusher places moving rail head portion, and one (totally four, all interlocks) respectively pacified in both sides.Each pusher partly is made of front and back two again:

1, pusher front portion: mainly be that the rail head bolt is released in the wedging switch track rail head bolt hole, make rail switch track head be able to fastening locking.(being about to the rail head bolt in the time of need pulling track switch retracts in the pusher).

2, pusher rear portion: mainly be with moving rail locating clamp plate (be called for short clamp, down with) promote in the wedging locating groove will the moving rail of full section another side fix.(need only extract out in the locating groove synchronously with bolt in the time of need pulling track switch and get final product).

So far, moving rail (track switch) head and both sides are all by firm fixation, and train steadily safety passes through.

The utility model has following positive beneficial effect:

1, this track switch has been adopted and has been had only two moving rails, and moving rail can adopt the common rail identical with circuit.Thereby saved high standard and sternly required parts resemble the tongue.

2, because of having saved the problems that the tongue stock rail has also saved tongue and stock rail, as: the manipulation fault that gets involved because of foreign matter etc.Make and handle flexibility and reliability more, reduce fault.

3, adopt the square butt joint of moving rail and switch track, just common as the butt joint of two common one steel rails.Train operation is steady and smooth safety more.Can improve train running speed.

4, the annex installation and maintenance are simple and convenient, and are cheap.

5, this track switch is preferably installs the installation on prefabricated sleeper on advanced person's curing railway roadbed.

No split switch of the present utility model comprises that point mechanism is installed on the turnoff of two railway lines.(seeing Fig. 1, Fig. 2).Switch track section 2 does not change substantially, only at the head of switch track 2 eight (have four switch tracks, install 2 for every) rail head bolt hole 7 (fixedly the rail head bolt is with seeing Fig. 3) is installed.It is standard gauge 1435mm that moving rail 1 is made up of between two strands 2 rail identical with circuit.Fix by cylinder lever connecting rod.Pull when point mechanism will move rail 1---when moving rail A-share 101 is aimed at switch track AZ thigh 201, moving rail B thigh 102 aligning switch track BZ thighs 203, line clear straight line (see figure 1); Pull when point mechanism will move rail 1---moving rail A-share 101 aims at switch track AC thighs 202, when moving rail B thigh 102 is aimed at switch track BC thighs 204, and this has just realized that the road divides due function line clear side line (see figure 2), train or shunt can be freely any circuit of turnover.

The operating principle of pulling, locate, fixing (locking) of no split switch of the present utility model is such: when point mechanism is pulled track switch, through driving bevel gear 302 this revolving force is passed to the rail head bolt bevel gear 303 of front portion (equally also passing to the rear portion) and is rotated affixed with it bolt screw shell 304 for earlier 301 1 revolving force (see figure 5)s of driving shaft of pusher 3, pulling bolt push rod 305 related bolts 306 retreat, in the withdrawal pusher (synchronous), cancelled fixing between moving rail 1 and switch track 2 rail heads with moving rail locating clamp plate.When the anterior bolt bevel gear 303 of driving shaft bevel gear 302 rotation drives moves, also drive 307 rotations of rear portion clamp clutch bevel gear synchronously and drive 308 rotations of clamp screw shell, and 309 withdrawals of pulling clamp spiral handspike, move and drive clamp pusher arm 3013 and clamp connecting rod 3014 and moving rail locating clamp plate 3015, recess moving rail locator card 4 (synchronous), cancelled moving rail (track switch) side and fixed (locking) with the rail head bolt.This moment, point mechanism stopped the rotation to latch fitting pusher driving shaft 301.Pull track switch (moving rail 1) to the precalculated position, the position that promptly moving rail locator card 4 is limited.Firm fixation in the moving rail locating groove 402 of this side moving flange of rail limit wedging this moment.Opposite side then repeats above-mentioned reverse action by moving rail location latch fitting pusher 3, can will move rail head portion and opposite side firm fixation (seeing Fig. 4,5,6)

Pulled the precalculated position at track switch, promptly moving rail 1 is positioned card 4 when limiting positions, and the umbrella tooth at pusher 3 rear portions of its homonymy clutch knob 3011 fixedly clutch knob shelves 3012 that also are set at homonymy simultaneously outward is pressed into and arrives and make clamp clutch bevel gear 307 leave driving bevel gear 302 and this pusher rear portion be failure to actuate (seeing Fig. 4,5).That is be that the moving rail locator card of homonymy is pulled 3015 to be in the room motionless.Opposite side (seeing Fig. 3,4,5,6) by fixing moving rail 1 in the moving rail locating groove 402 of the moving rail locating clamp plate 3015 action wedgings of opposite side.

So far, promptly be the once full course of work of no split switch of the present utility model.Pull this track switch later at every turn and all repeat said process.

This nothing split switch only needs point mechanism to there emerged a revolving force and be used for release and locking (reinforcing) to this track switch pulling respectively to give before and after the track switch than former track switch more.
