Embodiment
Below in conjunction with accompanying drawing 1-4, the monolateral structure squeezing switch apparatus of the present utility model is described in detail.
One is monolateral squeezes switch apparatus, and the described monolateral switch apparatus that squeezes comprises trouble point 9, basic rail 10, action bar 11, action spring 12, position switch 13,14, piston 15, cylinder cylinder 16; Described trouble point 9 and described cylinder cylinder 16 are positioned at the both sides of basic rail 10; Described piston 15 is arranged in cylinder cylinder 16, and can along the axially reciprocating of cylinder cylinder 16; Described trouble point 9 is connected with described action bar 11, described action bar 9 is positioned at same axis place with described piston 15, the two ends of described action spring 12 connect the first end 17 of described action bar 11 and piston respectively, and under the elastic force effect of described action spring, trouble point can be close to by described action bar with basic rail; Wheel is separated through out-of-date can being squeezed with basic rail by trouble point; Described position switch is relative with the 2nd end 18 position of above-mentioned piston, and the 2nd end of described piston or can be separated to connecing with described position switch when to-and-fro movement. The quantity of described position switch is 2, and the zygomorphy laying respectively at above-mentioned piston axis is arranged. Described cylinder cylinder is that hydraulic cushion cylinder cylinder or pressure buffer cylinder cylinder are used for making trouble point speed to squeeze going back at a slow speed position. Whether described position switch is close to basic rail by expression trouble is sharp, and for whistle control system acquisition and processing. Described position switch is connected with track switch traffic signalization system, and the point that branches off also is provided with pressure transmitter with the contact surface of basic rail, described pressure transmitter is connected with described track switch traffic signalization system and is used for described track switch traffic signalization system according to the action of pressure signal control piston to guarantee that trouble is sharp and basic rail is close to. Described cylinder cylinder is also provided with hydraulic circuit or gas path failure warning, and described warning is connected with described track switch traffic signalization Systematical control. Described position switch is also connected with position switch and connects pilot lamp.
The monolateral using method squeezing switch apparatus comprises the steps:
1) monolateral the exit end that switch apparatus is arranged on the unidirectional route track of usual friendship is squeezed by described;
2) when train sails into before track switch, described spring 12 utilizes elastic force will branch off point together with basic rail pressure by action bar;
3) when train sails track switch into, described trouble point can be separated with the extruding of basic rail under pressure effect in the vehicle wheel of train, piston 15 stretch out motion under, the 2nd of piston corrects in time connecing position switch 13,14, represents that position switch is connected;
4) when train rolls track switch completely away from, under the retracting motion of piston 15, the 2nd end of piston is separated with position switch 13,14, representing that position switch disconnects, described spring returns to step 2) in will the state of trouble point together with basic rail pressure by sense of movement.
Operation rule according to tramway usual friendship crossing, can only one direction travel at usual friendship crossing, and namely in Fig. 1, " 1 ", " 2 " number track switch are direct motion state all the time. In FIG, the running status of " 1 ", " 2 " number track switch is always direct motion (namely not allowing reverse driving), so in FIG, " 1 ", " 2 " number track switch can adopt monolateral squeezes track switch.In fig. 2, when train by first party to after entering, trouble point 8 carries the weight of train with basic rail 5, trouble point 7 is easy to be squeezed; When train is sailed into by second direction, basic rail 6 and the trouble point 7 carrying weight of train, trouble point 8 is easy to be squeezed. The track switch used due to modern tram is grooved track turnout, and base groove defines natural guard rail, as long as a trouble point puts in place, even if another trouble point cannot squeeze, also can not cause derailing, slide down. In figs. 3 and 4, spring 12 utilizes elastic force will branch off point together with basic rail pressure by action bar, when piston 15 is just in time connecing position switch 13 and 14, represents that position switch is connected, and illustrates that trouble point is closely connected with basic rail, otherwise by processing without expression.
When the track switch 1 and 2 of such as Fig. 1 be replaced with monolateral squeeze track switch after, whistle control system only considers control track switch 3 and 4, that is signalling system only considers the track switch direction of ingress, so it is hostile without the need to considering, as long as so signalling system knows that train traveling demand just can move track switch immediately, and provide route instruction, as long as society's signal lamp allows tramway to pass through like this, switch location is ready to for a long time, and what this just greatly improved usual friendship crossing passes through ability. This is monolateral squeezes switch apparatus and can be made into and open soon, the buffer-type device closed slowly, it is possible to greatly improve the work-ing life of its track switch.
The above-mentioned description to embodiment can understand for ease of those skilled in the art and apply the utility model. These embodiments obviously easily can be made various amendment by person skilled in the art, and General Principle described herein are applied in other embodiments and need not pass through creative work. Therefore, the utility model is not limited to embodiment here, and those skilled in the art, according to announcement of the present utility model, do not depart from improvement that the utility model category makes and amendment all should within protection domain of the present utility model.
