A turnout includes a fixed beam, and a first and a second movable beams respectively on two opposite sides of the fixed beam. The fixed beam is arranged on a turnout platform. The first movable beam is movably arranged on the turnout platform between a first and a second positions. The second movable beam is movably arranged on the turnout platform between a third and a fourth positions. When the first movable beam is at the first position, the second movable beam is at the third position, the first movable beam is separated from the fixed beam, and the second movable beam and the fixed beam form a first passage; when the first movable beam is at the second position, the second movable beam is at the fourth position, the second movable beam is separated from the fixed beam, and the first movable beam and the fixed beam form a second passage.

Disclosed is switch lock device of a railway switching actuator connected to a switching slide and a tie bar/locking slide of the actuator, the switching slide and a tie bar/locking slide being slidable one over the other to lock a blade of a railway switch in a closed position, the switch lock including an oscillating catch unit oscillating between two positions, engaging either a stationary step of a casing of the actuator or a head surface of the switching slide. The oscillating catch unit links to the end of the tie bar by a spring actuated mechanism blocking oscillation of the oscillating catch unit in an unlocked position corresponding to the engagement of the switching slide. During switching, the tie bar compresses the spring actuated mechanism, and the oscillating catch unit is free to oscillate towards a locking position, engaging the step of the casing of the actuator.

A switch device for moving switch rails. The switch device includes a motor operatively coupled to move the switch rails into and between first and second positions. The motor is configured for electricity to flow therethrough along a first path and a second path. A first path relay has two normally open contacts each within the first path, where activating the first path relay closes the two normally open contacts thereof. A second path relay has two normally open contacts each within the second path, where activating the second path relay closes the two normally open contacts thereof. The motor moves the switch rails towards the first position when the first path relay is activated and the second path relay is deactivated, and the motor moves the switch rails towards the second position when the second path relay is activated and the first path relay is deactivated.

The present disclosure discloses an interlocking protection device for turnout switching. The interlocking protection device for turnout switching comprises a receiving module, a confirmation module, a processing module, and a centralized control interlocking module, wherein the receiving module is configured to receive a turnout switching instruction; the confirmation module is configured to receive a confirmation instruction; the processing module is configured to determine a target turnout position according to the turnout switching instruction and output a driving confirmation signal according to the confirmation instruction; and the centralized control interlocking module comprises a confirmation unit and a position switch unit. Under a centralized control mode, the confirmation unit carries out separate turnout locking according to the target turnout position and carries out locking confirmation according to the driving confirmation signal. After locking confirmation, the position switch unit closes target turnout position switches and opens the other turnout position switches.

A track switch that comprises track rails of basic (2), (3), straight, (4), (5) and lateral (6), (7) directions fastened on a slab track (1); sliding switch rails (8), (9) and point rails (10), (11) that are rigidly fastened to the slab track (1) by means of mounting means (12). The point rails and switch rails form points. The track switch comprises also a shift mechanism with a drive (14) and an axis (15), whereto sliding locks (16), (17) are connected. The point rails (10), (11) and the switch rails (8), (9) are connected with each other by means of units. Each of the units is a guide (18) that is rigidly fastened to the point rail, a wedge (19) that is rigidly fastened to the switch rail (8), (9), a cleat wedge (20) placed in the guides that is capable of moving longitudinally and fastened with its both ends to point rods (21) of the wedge (see FIGS. 1 and 4). The sliding wedges (20) are connected to each other by means of point rods (21), the last of the point rods being connected with the axis of the shift mechanism that is capable of rotating or moving longitudinally, and is set into motion by a shift drive mechanism. The sliding switch rails (8), (9) are connected to each other by means of spacing rods (22).
