Definitions
- the invention relates to a device for supporting the displacement movement and for elastically locking movable switch parts, in particular switch tongues of grooved rail switches, with an axially displaceable tube or a rod which has recesses on its periphery for receiving radially displaceable ones Has locking members and a tube concentrically surrounding the pipe or rod, which has recesses for receiving radially outwardly displaced locking members.
- Embodiments of a changeover aid have also become known from AT-PS 379 624, a spring rocker being used here in which an angle lever is mounted at the crossing point of the arms, an energy store being supported against the arms of the two angle levers by means of a compression spring.
- Two spring rockers were connected to the two tongue rails via a coupling rod.
- the invention now aims to develop a device of the type mentioned in such a way that it can be made particularly compact and short and can be used both in rail switch actuators and as a changeover aid for switches.
- the compact design should allow the retrofitting of existing switches in a simple manner and should be particularly suitable for grooved rail switches.
- the design according to the invention consists essentially in the fact that the locking members are mounted in two separate pipe sections or cages arranged at an axial distance from one another between the pipe and the rod, and that a compression spring acting in the axial direction is arranged between the pipe sections or cages .
- a compression spring acting in the axial direction is arranged between the pipe sections or cages .
- the training is such that.
- the axial spacing of the recesses for the locking members in the tube is chosen to be different from the axial spacing of the recesses on the rod.
- Such a coupling rod connecting the switch tongues can be connected directly to a drive, so that instead of the existing actuating rod of the switch drive, the device according to the invention can be used directly as a drive rod.
- the exchange of existing coupling rods is possible without any structural changes.
- the design according to the invention is such that the recesses for the locking members are designed as circumferential or ring grooves and the locking members as balls.
- the pipe sections can be designed as ball cages in a manner known from bearing construction, so that a particularly simple design is made possible.
- the design is advantageously made such that the annular grooves have a trapezoidal cross section.
- the design is such that the cages for the locking members are sealingly guided between the rod and the tube, and that the annular space containing the compression spring has non-return valves that open outwards and a throttle that is connected in parallel with these valves and that is located outside the spring space Annular spaces is connected.
- the final phase of the changeover movement is hydraulically damped, the fluid being pressed out of the outer annular space into the spring space. With appropriate dimensioning of the cross sections, this can be ensured when the annular spaces are completely filled with fluid.
- the compression spring In order to ensure that the compression spring can be used as a device to support the displacement movement, starting from its resilient locking position or end position, it must be ensured that the spring can be further compressed in the first part of the displacement movement in order to reduce the pressure in the sequence to make stored spring force available as a changeover aid.
- the design is therefore advantageously made such that the compression spring is partially relaxed in its position corresponding to one end position of the device.
- the compression spring can be designed as a helical spring.
- a further and possibly additional form of damping of the changeover movement can be realized in that the rod carries stops which cooperate with damping devices, in particular a hydraulic damper, in each end position of the device.
- FIG. 1 shows a view of the adjusting device according to the invention, partly in section with the point machine
- FIG. 2 shows a plan view of the changeover aid in the direction of arrow II of FIG. 1
- FIG. 3 shows an enlarged illustration of the device according to the invention in a first left end position 4 shows a representation analogous to FIG. 3 in a transition position during the changeover movement
- FIG. 5 shows the beginning of the relaxation of the compression spring to support the changeover movement to the right
- FIG. 6 shows the right end position of the device according to the invention
- FIG. 7 shows a schematic representation an additional hydraulic damping in an embodiment according to FIGS. 3 to 6.
- FIG.l a grooved rail switch can be seen, the movable switch tongues with 1 and the stock rails with 2 are drawn.
- the switch tongues 1 are coupled via coupling pins 3 to a rod 4, which can itself be displaced in the direction of the double arrow 6 by a schematically indicated drive 5.
- 7 schematically shows the device according to the invention for supporting the displacement movement and for elastically locking the tongue rails 1, which is illustrated in more detail in the following FIGS. 3 to 7.
- Fig.l it can also be seen that the rod carries 4 stops 8. As can be seen in particular from the top view according to FIG. 2, these stops 8 come into contact with a hydraulic damper, indicated schematically by 9, after a predetermined path a, so that the end position of the adjustment movement takes place under the influence of the damping of the hydraulic damper 9.
- a hydraulic damper indicated schematically by 9
- the rod 4 On its circumference, the rod 4 has trapezoidal grooves 10 and 11 in cross section, the axial spacing of which is chosen to be b.
- the locking members 14 and 15, which are designed as balls, are arranged in ball cages 12 and 13.
- the fixed outer tube 16 has grooves 17, the effective axial distance between these grooves 17 being chosen to be different from the distance b.
