One side squeezable turnout device and using method thereof

Abstract

The invention relates to a single-side extrudable turnout device and a use method thereof. The single-side extrudable turnout device comprises a switch blade, a stock rail, an actuating rod, an actuating spring, position switches, a piston and a cylinder barrel. The switch blade and the cylinder barrel are located on the two sides of the stock rail. The piston is arranged in the cylinder barrel and can move in a reciprocating mode in the axial direction of the cylinder barrel. The switch blade is connected with the actuating rod, the actuating rod and the piston are located on the same axis, the two ends of the actuating spring are connected with the first end of the actuating rod and the first end of the piston respectively, the actuating rod can enable the switch blade and the stock rail to be tightly attached under the elastic effect of the actuating spring, and the switch blade and the stock rail can be extruded to be separated when wheels pass. The position switches and the second end of the piston are opposite in position, and the second end of the piston can abut against or be separated from the position switches when the piston moves in a reciprocating mode. The single-side extrudable turnout device has the advantages that the structure is simple, design is reasonable, performance is stable and reliable, the passing time of rail transit on a turnout intersection can be saved, the passing capacity of a level crossing is improved, and the service life of a turnout is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of rail transit turnouts, in particular to a single-side squeezable turnout device and a method for using the same. Background technique [0002] All rail transit involves turnouts, and turnouts are also one of the core equipment of rail transit. Generally, turnouts have two positions: positioning and reverse (ie straight strands, side strands). Generally speaking, one approach involves multiple turnouts, and different approaches are listed through the combination of turnouts and stock tracks. The operating principles of rail transit signal equipment are: (1) routing; (2) approach locking; (3) Vehicles are pushed in sequentially and driven out sequentially; (4) The routes are unlocked. The various equipment elements used on the way forward without unlocking the route cannot be used by other routes. [0003] At present, with the development of modern urban trams, the traditional operation mode has had a gre...

Problems solved by technology

At this time, if the friction coefficient of the sliding bed is too large or there is a foreign object between the tip of the switch and the basic rail, it may cause the switch to be unable to squeeze through and cause a derailment accident. So no one dares to use this type of switch in China so far.
