A device for locking end positions of switch parts, having two parts, relatively axially displaceable and positively coupled in at least one direction, including a tube and a rod guided within the tube, at least partially arranged in an outer tube. Locking members cooperate with the parts and outer tube and are displaceable into a locking position in the outer tube's recess. Locking members include ring segments chamfered on insides forming first abutment surfaces converging obliquely toward rod axis. First abutment surfaces cooperate with oblique counter abutment surfaces in a rod recess for holding the rod and the tube coupled during the rod's first displacement path and for urging segments outwardly to emerge from rod recess, and to slide onto the rod's outer surface adjacent rod recess and to immerse into locking position in the outer tube's recess upon rod movement relative to the tube over a second displacement path.

Device for locking the final positions of moving switch points

In a device for checking the operation of devices () used to displace movable switch parts (), in which the movable switch parts () are connected with each other by a coupling rod (), the coupling rod () is comprised of two coupling rod parts () that are relatively movable in the axial direction. Sensors () are provided for the detection of at least two different displacement positions of the coupling rod parts ().

Device for mechanically and electrically checking the switching device of a railway switch machine

A method for installing railway switches in tracks is characterized in that the switch completely preassembled in functional units () is transferred onto a transport vehicle, and that the tongue region, the rail interspace region and the core region including preassembled sleepers (), the movable switch parts such as, e.g., the tongue device and the safety devices are lowered on the installation site in the preassembled state and connected with the adjoining rails, whereupon the switch is ballasted and the track ballast is packed, the connection ducts for the switch mechanism and the switch safety devices are connected and the switch is put into operation. In the railway switch capable of being transported in the preassembled state, the actuating drives are designed as hydraulic actuators (). The hydraulic lines () for the connection of the actuating drives are elastically fixed to the sleepers (). The actuating drives () are connected to the movable switch parts such as, e.g., tongues () in a manner pivotable about an axis extending in the longitudinal direction of the rails with elastic connection elements and/or crowned bearings () being interposed.

Method for installing points in railway tracks and points for carrying out said method

The invention relates to a device for displacing and locking movable switch parts (), comprising a hydraulic piston, which is formed by a rod () and cooperates, via coupling or locking members (), with an axially displaceable sleeve () intended to receive the radially displaceable coupling or locking members (), The displaceable sleeve () is coupled with the movable switch parts () and an externally arranged tube (), at least partly overlapping the sleeve () and the rod (). A hydraulic duct () is connected to the externally arranged tube (), on a front face of the sleeve (), facing away from the coupling site for the movable switch parts ().

Device for switching and locking moving points components

A device for switching and elastically locking the end positions of movable switch parts, in particular switch tongues of grooved rail switches, including an axially displaceable rod ( ) and a tube ( ) surrounding the rod, in which a spring ( ) encompassing the rod is braced against stops and locking members ( &prime;) capable of being displaced radially outwards are arranged, wherein the rod ( ) has axially spaced-apart control stops ( ) for a radially inward position of the locking members ( &prime;) and the tube ( ) has stops ( ) for the outward position of the locking members ( &prime;), wherein at least one ( ) of the control stops ( ) of the rod ( ) is displaceable relative to at least another one ( ) of the control stops ( ) in the axial direction of the rod ( ) and is capable of being fixed in the respective displaced position.

Device for adjusting and elastically locking moveable switch parts

In a device for displacing the movable parts of rail switches or crossings, in which a plurality of hydraulic cylinder piston units engaging in an offset manner in the longitudinal direction of the rails are each connected in series, at least one directional or seat valve ( ) capable of being adjusted in a pressure controlled manner is inserted in the duct ( ) that connects the hydraulic cylinder piston units ( to ) arranged in series, which directional or seat valve blocks the connection to the consecutive cylinder piston unit if a preset differential pressure is exceeded.

Device for displacing the moveable parts of rail switches or crossings

A device for locking the end positions of movable railway switch parts in which two parts axially displaceable relative to each other are displaced into a position coupled to each other for movement in at least one direction. The relatively displaceable parts, formed by a tube and a rod guided within the tube, are arranged at least partially within a stationary external tube. Locking elements comprising balls cooperate with the axially displaceable parts and the external tube and are displaceable radially into a lock position within a recess of the external tube. The balls are surrounded by a ring resiliently held in a position having an outer diameter smaller than, or equal to, the outer diameter of the axially displaceable tube retained in a peripheral groove of the tube. The balls are arranged in openings in the tube between the rod and the ring.

Device for locking end positions of mobile switch parts

In a connecting device for a switch actuator and/or a lock for movable parts of a railway switch or crossing, including a rod assembly, in particular a sliding rod or a locking rod articulately connected with the movable part, the movable part or the rod assembly, in particular the switch tongue (,), is rigidly connected with a strap (,) engaging from behind a pin (,) connected with the rod assembly or the movable part for transmitting tensile forces. Between the rod assembly and the strap (,) or the movable part is arranged at least one elastic compression element, which is compressible by the rod assembly in the abutment position of the movable part on a rigid rail part, the strap (,) being displaceable out of abutment on the pin (,).
