Definitions
- the invention relates to a device for locking the end positions of movable switch parts, in particular switch lock, in which two parts which are axially displaceable relative to one another can be displaced in a position which is non-positively coupled to one another in at least one direction of movement, the parts displaceable relative to one another by a tube and a are formed in the tube guided rod and are at least partially arranged in a stationary outer tube, locking members formed by balls cooperate with the axially displaceable parts and the outer tube and are radially displaceable in a locking position in a recess or inner ring groove of the outer tube.
- Coupling rods of this type are usually prescribed by the relevant railway administrations for safety reasons. While during the sliding movement of the tongue, the forces to be absorbed by the ball are limited by the maximum permissible sliding force, the balls can be subjected to higher loads in the locking position. Conversion forces are usually in the order of 150 kp, whereas the forces acting on the locking components can be in the range of 10,000 kp and more. Since these locking forces can only be absorbed by balls via a line point contact, the contact points are exposed to an excessively high load, which can lead to inadmissible deformations.
- the invention now aims to improve the function in a device of the type mentioned and also to ensure the absorption of extremely high locking forces without the risk of premature impairment of the locking function.
- the inventive design consists essentially in that the balls are surrounded by an expandable ring or a ring consisting of segments, that the segments or the ring are held resiliently in a position with an outer diameter which is less than or equal to Outside diameter of the axially displaceable tube guided in the outer tube and immersed or immersed in a circumferential groove of the tube and that the balls are arranged in openings in the tube between the rod and the ring consisting of segments.
- the balls no longer interact directly with the edges of the grooves of the outer tube in the locking position, excessive edge loading is avoided and the correspondingly high load is absorbed by the ring segments or the expandable ring, which in turn can have a corresponding cross section. to ensure a flat contact on the side walls of the grooves effective for locking.
- the fact that these segments are now pulled resiliently is simultaneously ensured when the rod is displaced into a position in which the balls can move back to an area of reduced cross section that this radially inward movement of the balls is supported by the force of the springs , so that a minimal displacement resistance is ensured between the component coupled to the tongue and the outer tube.
- the segments of the ring are immersed in a circumferential groove of the tube, the balls themselves, as in the known design, being guided in radial openings in the tube.
- the design is such that the ring segments for the axial displacement direction have normal or inclined end faces which cooperate in the locking position with the stops of the outer tube, so that effective and safe support of high locking forces in the locking position is guaranteed.
- the spring of the ring segments can be formed by springs running in the circumferential direction or a spring band.
- the individual ring segments can be connected to one another by separate springs, an embodiment with an external continuous spring band being particularly simple to manufacture.
- the design is advantageously made such that the rod has two axial areas at a smaller diameter in its end area and has an intermediate axial region of full diameter, the axial length of which is less than the distance between two balls adjacent in the axial direction of the tube.
- each axially displaceable tube connected with a switch tongue has openings which are offset in the axial direction at an axial distance (II) and that the outer tube is at least two to one another with a radius exceeding the diameter of the inner tube has oppositely arranged stops at an axial distance (12)> dl), the distance (I2) less the distance (l ⁇ ) corresponding to the axial displacement path between the adjacent and remote end position of a tongue.
- the locking of the remote tongue can be ensured by an inner plane of balls and segments and the locking of the tongue in contact position by an outer plane of balls and segments, while at the same time it can be ensured that the desired direction the locking is achieved in both cases. In other words, this means that the tongue in contact is secured against moving back to a storage position and the tongue in storage is secured against movement in the contact position.
- the device according to the invention for locking the end positions can at the same time be used as a drive for moving the tongues into the contact position or into the storage position.
- a compact displacement drive can be designed particularly simply in that the displaceable rod immersed in the tubes is designed to be continuous over its axial length and is connected in a central region to a drive device, in particular a piston, which is in a cylinder of a double-acting cylinder-piston unit trained outer tube is axially displaceable by fluid.
- the rod thus acts as a piston rod of a double-acting cylinder piston unit and because of the two in each case arranged offset in the axial direction Rings with the respective ring segments and the associated balls, one of the levels created in this way can be used for the displacement drive and / or the locking.
- the balls In the locking position, the balls rest on a partial area of the rod with the full diameter and therefore cannot be moved in the axial direction when the rod is displaced, since they are locked in the circumferential groove of the outer tube. If such an external locking plane consisting of balls and ring segments is subsequently brought into an unlocking position by moving the rod, these same balls cannot be used for a displacement drive of the tube connected to the tongue when they rest on the end region of the rod .
- a stop shoulder of the area lying on a larger diameter must subsequently grip the internal balls for the displacement drive and in this way that external tubes connected to the tongues take along over the adjustment path of the tongues.
- This adjustment path extends into a further area of the outer tube, in which the balls can in turn pass through to the outside and emerge into a new locking position for the tongue which is now removed, the displacement of the tongue from this storage position being prevented in this way.
- the axial area with a full diameter which is provided in the end area and has a smaller diameter, must have an axial length which is less than the distance between two balls which are adjacent in the axial direction of its tube, in order to ensure that the unlocking has occurred before the shifting movement is initiated.
- the design according to the invention is advantageously made such that the outer tube has a further annular recess on each side of the cylinder between the recess adjacent to the cylinder for locking an end position of the tongues and the second recess for locking the opposite end position of the tongues has a clear width which is less than the clear width of the locking recesses for securing the end position.
- Such training offers additional security if, for example, the coupling rod is broken. In the event of a break in the coupling rod, the displacement of a remote tongue into the adjacent position no longer results in the synchronous displacement of the originally adjacent tongue into a remote position, since this forced coupling was achieved via the coupling rod.
- the tongue which originally bears against it, is also moved into a storage position by the stop shoulder and the balls, but the correct storage position is not ensured, which would only be achieved if a coupling rod was present.
- the tensile load on the balls which become effective for the drive in this case would be sufficient to displace these balls together with their ring segments into the further annular recess in between, with the result that a further displacement is no longer possible.
- proximity sensors or switches dependent on the displacement path are arranged on or near the end faces of the cylinder penetrated by the piston rod, a signal would be generated in this case which would indicate an incorrect position of the remote tongue signals what can be concluded from a break in the coupling rod.
- the design according to the invention is advantageously made such that in an end position of the tongues the distance (I3) of the balls facing the cylinder on a smaller diameter of the rod and that of the axial area with the full diameter stop is greater than the distance (I4) of the outer balls of the part of the rod opposite the cylinder from the stop adjacent to these balls, which is formed by the axial area with the full diameter.
- the coupling rod fulfills its function, an unintentional escape of the leading balls into the intermediate recess of the Outer tube is avoided and further movement is in no way prevented. Only when the coupling rod is broken do these balls reach the corresponding counter stop of the area of the rod widening to the full diameter and are brought into a position in which the further displacement of the rod is no longer possible.
- the design according to the invention is advantageously made such that, in an end position of the rod, the axial distance (I5) of the balls lying on the full cross section, in their locking position, is greater than the distance (16) of the balls at the opposite end of the rod of the rod against the full cross section of axially inner balls from the inner stop formed by the full cross section of the rod.
- the axial width of the outer locking grooves of the outer tube is advantageously greater than the axial width of the ring consisting of segments, which ensures that the segments enter securely under the pressure of the locking members into the locking position of the outer tube.
- the device according to the invention is also suitable for a design in which the switch can be opened.
- a first unit facing away from the end of the tongue must be designed such that it can be opened under the force of the rolling load, a corresponding hydraulic coupling being able to release the locking of the subsequent units.
- the design is such that, when a plurality of devices for interlocking in the longitudinal direction of the rail for locking the end positions are arranged, at least one device counteracts them the force of a spring has displaceable locking members which, after a predetermined displacement in the axial direction with compression of the spring, can be displaced outward in the radial direction and release the further displacement of the rod and that the fluid spaces of the cylinder-piston units of adjacent device are connected to one another for the same displacement of the pistons.
- the design in such cases is such that the springs are designed as helical springs concentrically surrounding the piston rod, which are supported between the end walls of the cylinder-piston unit and a spring plate displaceable in the outer tube against a stop of the outer tube, the one in the outer tube displaceable spring plate distributed around its circumference in radial openings of the spring plate carries radially displaceable balls.
- a spring plate which carries the balls displaceable in the radial direction, ensures that the compression stroke extends only over a limited path and, as a result, the free displacement of the rod and thus the complete unlocking is ensured.
- the balls are placed in their spring plate in a radially outward position, in which the spring does not have to be compressed further for the further displacement of the rod.
- the tongue that is in contact with each other is carried into the shelf when it is opened by displacement forces which act on the remote tongue Tongue take effect.
- this embodiment which relates to the areas of the switches that are furthest away from the end of the tongue, there is generally no further track or coupling rod provided, since the coupling rods are usually arranged near the switch drive itself.
- the design is advantageously made such that the rod interacting with axially acting springs has a head with the diameter at its end faces of the rods exceeding diameter, which cooperates with axially external stops of the tube.
