Definitions
- the invention relates to a device for switching points, in which a plurality of coupled hydraulic actuating devices are arranged offset in the longitudinal direction of the rails and the cylinder-piston units of the hydraulic actuating devices are connected to each other to drive in the same direction.
- a device has become known, for example, from WO 96/00160.
- Hydraulic cylinder piston units has been proposed in WO 96/00160 to arrange poppet valves within the piston stroke of the hydraulic cylinder piston unit, which, for example, line connecting the two working spaces of the cylinder piston unit, e.g. were switched on in the form of a bore in the piston. Depending on the piston position, this connection is interrupted or there is a flow, whereby the target position can be reached exactly. This results in hydraulic synchronism of the hydraulic cylinder piston units, which are offset and coupled to one another along the longitudinal direction of the rails.
- a changeover device consists of a plurality of hydraulic cylinders with different cross sections, so that the installation of such a changeover device is complex due to the large number of different dimensions.
- the manufacture and assembly of the hydraulic cylinders is also more expensive, since everyone is involved. parts connected to the hydraulic cylinder piston unit or all parts arranged in the cylinder, such as end position safety devices, safety locking devices and / or sensors, must be adapted to the different dimensions.
- the installation dimensions of the differently dimensioned hydraulic cylinders also change accordingly, making installation even more difficult.
- the present invention now aims to provide a device for switching points, in which an exact setting of the required travel and actuating forces succeeds, while at the same time the installation dimensions of the hydraulic cylinders remain unchanged and, moreover, those required for the U actuating device Variety of parts of the hydraulic units can be kept as low as possible.
- the invention essentially consists in the fact that the working spaces of the hydraulic cylinder piston Aggregates each have two areas with a defined cylinder cross-section, the areas containing the end-position securing devices, safety locking devices and / or sensors of the cylinder piston assemblies which are offset in the longitudinal direction of the rails and have the same cross-section and the other areas of the i longitudinal direction of the rails staggered cylinder piston units have different cross sections.
- the other area of the cylinder-piston units is now designed with a different cross section in order to be able to adapt the adjustment stroke to the different circumstances along the longitudinal direction of the rail. At the same time, it succeeds in optimizing the actuating forces required in each case, with higher switching forces acting on the tongue with increasing proximity to the clamping point of the switch tongue. Due to the exact piston stroke adjustment, the remaining flushing volume is significantly reduced and thus the internal hydraulic losses of the changeover device are considerably reduced.
- the design is preferably developed in such a way that the area containing end position securing devices, safety locking devices, and / or sensors has a smaller cross section than the other area. As a result, the end position safety devices or safety locking devices arranged in the area in question can be arranged in an advantageous manner, wherein a particularly small-sized device can be implemented.
- the design is developed in such a way that the working spaces of the cylinder-piston unit are connected to one another by a bore in the piston and that blow-open valves are arranged in the bore.
- the working spaces of a cylinder-piston unit are in this case connected to one another by a line in the form of a bore. with burst valves are installed. These valves are actuated with a plunger that is firmly connected to the cylinder, so that the line connecting the two working spaces of the cylinder is opened and further adjustment of the piston is prevented.
- the design is advantageously developed in such a way that the cylinder is connected to a coupling flange with the interposition of a spacer, the length of the spacer corresponding to the stroke shortening caused by the cross-sectional enlargement of the cylinder.
- the spacers thus bridge the shortened stroke resulting smaller overall length of the cylinder, so. the installation situation and the attack situation for the linkage remain the same and the installation dimensions of the device are the same along the entire tongue rail.
- adjustments to the parts connected to the hydraulic cylinders can be reduced to a minimum, so that the effort for installation can be considerably reduced.
- FIG. 1 shows a plan view of a partial area of a rail switch
- FIG. 2 shows a detail of the
- FIG. 3 is a schematic partial view of the illustration of Fig. 2
- Figure 4 is an enlarged view of a conventional hydraulic
- Fig. 1 rails 1 are schematically indicated, which are connected to sleepers 2.
- tongue rails 3 are provided, which can be brought into their respective positions via an actuator, which is schematically designated by 4.
- the actuator 4 acts here via slide rods 5 on the tongue rails 3.
- the slide rods 5 are coupled to a hydraulic cylinder piston unit 7 via a central tap 6.
- cylinder piston units 7 are also additional cylinder piston units 7 in. Rail course can be seen, which are each coupled with slide rods and locking devices, which are in turn schematically designated by 5.
- the type of mechanical connection of the hydraulic cylinder-piston units 7 to the slide rods 5 can be seen more clearly.
- the cylinder piston units 7 have a sliding block 8 in which a pin 9 of the slide rod 5 engages.
- the sliding block and thus the piston of the hydraulic cylinder-piston units are displaced, as a result of which medium is pressed out of the respective working space.
- the type of fixing of the hydraulic cylinder piston units 7 on the threshold 2 is illustrated in FIG. 3. The determination is made via a stop plate 10, which is fixed on the threshold 2.
- the hydraulic cylinder piston units 7 require relatively little space, so that the plugging of the substructure is not impaired.
- FIGS. 4 and 5 The mode of operation of the hydraulic cylinder piston units and their preferred configuration is explained in more detail in FIGS. 4 and 5.
- a hydraulic cylinder piston unit 7 having a plunger 11 can be seen.
- the plungers 11 dip into the respective working spaces 13 of the hydraulic cylinder piston units via seals 12, and when the plunger 11 is displaced in one of the directions of the double arrow 14, medium is pressed out of the corresponding working space 13.
- the hydraulic connections open to the outer openings 15 in the respective work space 13.
- the sliding block is again designated 8, via which the mechanical coupling takes place.
- a rubber sleeve 16 is also provided.
- the device according to FIG. 4 can be seen in plan view.
- the individual hydraulic cylinder piston units are coupled to one another and arranged offset in the longitudinal direction of the rails, the first hydraulic cylinder piston unit acting as a pump element for the subsequent cylinder piston units.
- the working spaces 13 of the first hydraulic cylinder piston unit 7, which acts as a pump element, are connected to the corresponding working spaces via the hydraulic line 13 of adjacent hydraulic cylinder piston units 7, the connection being such that when the first hydraulic cylinder piston unit is used as a pump element, all other hydraulic cylinder piston units are coupled to move in the same direction.
- the working space 13 of the cylinder-piston unit 7 is formed in a first region 18 with a cross-section which is also the same in all the other cylinder-piston units arranged offset in the longitudinal direction of the rail.
- an area 19 of the working chamber is formed with an (enlarged cross-section, in this area, the cylinder cross-sections of the are in rail longitudinal direction are arranged offset cylinder piston units different from each other, in order to adjust the respectively required piston stroke.
- the end-position securing device in this case comprises locking members 20 designed as spheres, which are received in a driving sleeve 21.
- the locking members 20 cooperate here with stop shoulders, which are attached to a piston attached to the piston 11.
- End piece 22 is formed in the piston end piece 22, which opens or closes the bore 24, which axially penetrates the piston 11 and connects the two working spaces 13.
- the push-up valve is attached to the cylinder bottom Projection, for example in the form of a bolt s 25 is actuated, as a result of which the fluid of the hydraulic actuating drive can pass through the bore 24 into the respective other working space, whereby a further piston movement is prevented.
- a number of components are thus arranged in area 18 with a constant cross section, so that an adaptation of these components to the different cross sections of the area 19 is not necessary.
- a spacer 26 is provided, which is arranged between the hydraulic cylinder and the coupling flange 27.
- the installation length L is kept constant, so that overall the same fastening situation for receiving the cylinder-piston units can be found in all adjustment levels.
