It is bright.
It is a kind of it is monolateral squeeze switch apparatus, it is described it is monolateral squeeze switch apparatus include switch blade 9, stock rail 10, actuating strut 11,
Operating spring 12, position switch 13,14, piston 15, cylinder barrel 16；The switch blade 9 and the cylinder barrel 16 are located at the two of stock rail 10
Side；The piston 15 is arranged in cylinder barrel 16, and can be along the axially reciprocating of cylinder barrel 16；The switch blade 9 and the actuating strut
11 connections, the actuating strut 9 are located at same axis with the piston 15, and the two ends of the operating spring 12 connect described respectively
The first end 17 of actuating strut 11 and piston, and the operating spring elastic force effect under, the actuating strut can by switch blade with
Stock rail is close to；Switch blade can be squeezed with stock rail when passing through and be separated by wheel；Second end of the position switch and above-mentioned piston
18 positions are relative, and the second end of the piston can be abutted or be separated with the position switch when moving back and forth.Institute's rheme
The quantity for putting switch is 2, and the both sides positioned at above-mentioned piston axis are symmetrical arranged respectively.The cylinder barrel is hydraulic buffer cylinder
Cylinder or pressure buffer cylinder barrel are used to make switch blade speed squeeze return at a slow speed.The position switch by represent switch blade with stock rail be
It is no to be close to, and gather for whistle control system and process.The position switch is connected with track switch traffic signal control system, and
And switch blade is additionally provided with pressure transducer, the pressure transducer and the track switch traffic signalization with the contact surface of stock rail
System is connected to the track switch traffic signal control system and controls the action of piston to guarantee switch blade and base according to pressure signal
This rail is close to.The cylinder barrel is additionally provided with hydraulic circuit or gas path failure warning system, the warning system and the track switch
Traffic signal control system control connection.The position switch is also associated with position switch and connects display lamp.
The monolateral using method for squeezing switch apparatus comprises the steps：
1) by the monolateral port of export for squeezing switch apparatus installed in the unidirectional route track of usual friendship；
2) before train sails track switch into, switch blade and stock rail are pressed in one by actuating strut using elastic force by the spring 12
Rise；
3) when train sails track switch into, the switch blade can be extruded with stock rail under pressure effect in the vehicle wheel of train
Separate, piston 15 stretching out motion under, the second of piston correct abutted position switch 13,14 when, represent position switch
Jing is connected；
4) when train rolls track switch away from completely, under the retracting motion of piston 15, the second end and the position switch 13 of piston,
14 separate, and represent that position switch is already off, and the spring recovers to step 2) in by sense of movement by switch blade and basic rail pressure
State together.
According to the operation rule of tramcar level crossing, level crossing can only one direction traveling, i.e. " 1 " in Fig. 1,
" 2 " number track switch is direct motion state all the time.In FIG, " 1 ", the running status of " 2 " number track switch are always direct motion and (do not allow anti-
To driving), so in FIG, " 1 ", " 2 " number track switch can squeeze track switch using monolateral.In fig. 2, when train is by first direction
Into after, switch blade 8 carries the weight of train with stock rail 5, and switch blade 7 is easy to be squeezed；When train is sailed into by second direction, substantially
Rail 6 and switch blade 7 carry the weight of train, and switch blade 8 is easy to be squeezed.As the track switch that modern tram is used is grooved track
Trouble, foundation trench defines natural guard rail, as long as a switch blade is in place, even if another switch blade cannot be squeezed, does not also result in de-
Rail, slides down.In figs. 3 and 4, switch blade is forced together with stock rail by actuating strut by spring 12 using elastic force, when piston 15
Just during abutted position switch 13 and 14, represent that position switch has turned on, illustrate that switch blade is closely connected with stock rail, otherwise by without table
Show process.
When the track switch 1 and 2 of such as Fig. 1 be replaced with it is monolateral squeeze track switch after, whistle control system only consider control track switch 3 and 4
, that is to say, that signaling system only considers the track switch direction of porch, so need not consider hostile, as long as so signaling system
Know that train traveling demand can move track switch immediately, and provide route instruction, as long as so social signal lighties allow rail electricity
Car passes through, and switch location is early ready for, and this just greatly improves the handling capacity of level crossing.This is monolateral to squeeze switch apparatus
Can be fabricated to and open soon, the buffer-type device for closing slowly can greatly improve the service life of its track switch.
The above-mentioned description to embodiment is to be understood that for ease of those skilled in the art and apply this
It is bright.Person skilled in the art obviously easily can make various modifications to these embodiments, and described herein
General Principle is applied in other embodiment without through performing creative labour.Therefore, the invention is not restricted to enforcement here
Example, those skilled in the art's announcement of the invention, the improvement made without departing from scope and modification all should be
Within protection scope of the present invention.
