Definitions
- the invention relates to a device for switching switches, in which a plurality of hydraulic actuating devices coupled to one another are arranged offset in the longitudinal direction of the rails.
- a mechanical linkage In such devices for switching points, it is known to carry out the connection of the individual closures with a mechanical linkage.
- a mechanical connection of a plurality of actuating devices or closures requires a relatively large amount of space and a large number of individual parts which are different from one another.
- the pluggability of the tongue device is impaired with such a mechanical connection and, moreover, an unfavorable one-sided mass distribution is effected on a switch.
- a hydraulic actuating device is already known from EP-A2 480 303, in which a plurality of individual adjusting cylinders are controlled via a hydraulic station.
- Different circuit arrangements for the series connection or the parallel connection of a plurality of such hydraulic actuating devices are known from DE-B2 1952823.
- the known hydraulic actuating devices each require a separate hydraulic drive unit, which overall gives a relatively complex construction.
- the design according to the invention is developed in such a way that the pump element and the hydraulic actuating devices each contain a floating piston or plunger guided between two work spaces in a cylinder, the end faces or ring surfaces of the plunger respectively immersing in the opposite work spaces Pistons or plungers have identical cross-sectional area.
- a floating piston or plunger represents a structurally particularly simple, reliable and compact structural unit, which takes up the desired space in a small space Place can be arranged.
- a plurality of identical cylinder-piston assemblies of this type can be provided, the main advantage being that pressure is applied to identical cross-sectional areas, which results in a synchronous movement.
- the corresponding cross-sectional correction can be carried out in a simple manner by means of sealing elements or packings in such a configuration in order to ensure the respectively required adjustment path with a constant, displaced volume.
- Such a hydraulic actuating device with floating pistons or plungers thus, in addition to its compact design, also easily adapts to the respectively required requirements.
- the design can advantageously be such that the piston or plunger of the pump element has a bearing, in particular a sliding block with an annular groove or a bearing eye between it has free ends and that the bearing is protruding from an opening in the cylinder or between two fixed cylinders.
- a particularly simple and reliable compact design is possible, which is also suitable for subsequent installation in a simple manner.
- the annular surface of a piston can, as already mentioned above, ensure the required identical working cross section in both directions of displacement.
- a particularly simple construction is achieved in this case in that the piston is rigidly connected to a continuous piston rod which penetrates the cylinder and that the piston rod or the cylinder is fixed in place.
- the entire system is advantageously set at a predetermined excess pressure in relation to the atmospheric pressure. In this way, temperature fluctuations, which could lead to a change in pressure, can be buffered, for which purpose the design is advantageously made such that the working spaces of the cylinder-piston units are connected to a pressure accumulator via pressure relief valves.
- the overpressure valves are designed as controllable check valves, such controllable check valves resulting in a high degree of operational reliability. At high operating temperatures, medium is pressed out into the pressure accumulator by opening the check valves, whereas if the pressure drops, the pressure can be made available to the system again via the check valves.
- the design can be made in a particularly simple manner in such a way that a pressure-controlled directional control valve is connected to each of the pump work spaces which, when falling below a predetermined pressure, comes into the closed position, which ensures that in this case all adjusting devices are blocked. Blocking of the actuating devices would be signaled by the mechanical actuator and the corresponding control devices for the mechanical actuator at the corresponding point, so that the damage can be remedied immediately.
- An alternative to changing the cross-section to control a different adjustment position along the rail path is an embodiment which is preferably arranged such that blow-open valves are arranged in a line connecting the two working spaces of a cylinder piston unit, for example in the form of a bore . Depending on the piston or plunging position, this connection is interrupted or it there is flow, whereby the target position can be reached exactly.
- FIG. 1 shows a plan view of a partial area of a rail switch
- FIG. 2 shows a detail of the connection of a cylinder-piston unit with a mechanical slide rod
- FIG. 3 shows a schematic partial view of the illustration according to FIG. 2
- FIG. 4 shows an enlarged illustration of the Fig. 5 shows a top view of the representation according to Fig. 4
- Fig. 6 shows a schematic representation of the hydraulic connection of the individual cylinder piston assemblies
- Fig. 7 shows a modified design of the hydraulic connection
- Fig. 8 shows an alternative arrangement of hydraulic cylinder piston units in the course of the track
- FIGS. 9, 10 and 11 further alternative designs of cylinder piston units for the device according to the invention.
- Fig.l rails 1 are schematically indicated, which are connected to sleepers 2.
- tongue rails 3 are provided in addition to the control rails 1, which can be brought into their respective positions via an actuator, which is schematically designated by 4.
- Actuator 4 acts on slide rails 5 via slide rods 5.
- Slide rods 5 are coupled to a hydraulic cylinder piston unit 7 via a central tap 6. Additional hydraulic cylinder-piston units 7 in the course of the rail can also be seen, each of which is coupled to slide rods and locking devices, which in turn are denoted schematically by 5.
- FIG. 2 the type of mechanical connection of the hydraulic cylinder piston assemblies 7 to the slide rods 5 can be seen more clearly.
- the cylinder-piston units 7 have a sliding block 8, in which a bolt 9 of the slide rod 5 engages. When the slide rod 5 is actuated, the sliding block and thus the piston of the hydraulic cylinder piston units shifted, whereby medium is pressed out of the respective work space.
- the type of fixing of the hydraulic cylinder piston units 7 on the threshold 2 is illustrated in FIG. 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 show a hydraulic cylinder piston unit 7 having a plunger 11.
- the plungers 11 plunge into the respective work 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 work space 13.
- the hydraulic connections lead to the external openings 15 in the respective work space 13.
- the link block is again designated 8, via which the mechanical coupling takes place.
- a rubber sleeve 16 is also provided.
- FIG. 5 shows the device according to FIG. 4 in a top view.
- identical cross sections are effective on both sides.
- the cylinders of the hydraulic cylinder-piston unit are fixed via bolts 17 on the angle plate 10.
- the working spaces 13 of the first hydraulic cylinder piston unit 7, which acts as a pump element, are connected via hydraulic lines 18 to corresponding working spaces 13 of adjacent hydraulic cylinder piston units 7, the connection being such that when the first hydraulic cylinder piston unit, as the pump element, is displaced all other hydraulic cylinder piston units 7 at the same meaningful shift are coupled.
- the cross section must be influenced accordingly, for which purpose a corresponding sealing element can be arranged inside the cylinder to reduce the cross section.
- the hydraulic lines 18 now contain a series of valves in order to keep the pressure constant under operating conditions and to be able to reliably detect impermissible situations.
- a spring-loaded valve 19 is provided, which is acted upon by the hydraulic pressure in the lines 18. If the pressure in the hydraulic lines 18 drops below a limit value, the force of the spring of the spring-loaded valve 19 will move the spring-loaded valve 19 into the closed position, so that a further displacement of the hydraulic cylinder piston unit 7, which acts as a pump element, is prevented. In this case, the point machine is blocked and a corresponding fault message is issued.
- a pressure accumulator 20 is also provided, which is connected to the respective hydraulic lines 18 via overflow valves or check valves 21.
- the overflow valves or non-return valves are switched in such a way that when the pressure rises due to thermal expansion, fluid is pressed into the reservoir 20 and conversely, when the pressure drops slightly, fluid is pressed out of the hydraulic accumulator 20 into the lines 18.
- the spring-loaded safety valves 19 only become effective in the event of a leak and a corresponding pressure drop in the accumulator 20.
- FIG. 7 shows a simplified design of the hydraulic linkage.
- the reference numerals from FIG. 6 have been retained in FIG.
- a pressure accumulator 20 is connected to the entire hydraulic circuit, so that hydraulic fluid is returned to the accumulator 20 when a pressure relief valve 21 responds.
- the preload valves or safety valves 19 are acted upon by the accumulator pressure of the piston accumulator. Overpressure can occur, especially if the temperature increases due to sunshine.
- the piston chambers are in turn connected to one another in series, the pump element in turn being provided with the preload valves or safety valves 19. Both connecting lines are protected separately with pressure relief valves.
- modified hydraulic cylinder piston units 7 are provided, each of which engages at the ends of the slide rods 5.
- the modified cylinder-piston units 7 serve the same purpose as the design according to FIG. 1, but the functions for displacements to the left or to the right are separated from one another and no common plunger or piston is used for both working spaces finds.
- FIG. 9 again shows a modified design of the hydraulic cylinder piston units.
- the design is such that the same cross sections of a piston come into effect in the two work spaces 13.
- the piston 22 is connected to a piston rod 23 and in the present case the ring surface is effective or acted upon.
- the same components as in the embodiment according to FIG. 6 or 7 are used in this embodiment, and the same reference numerals have been used here again.
- a blockage in the event of a drop in pressure of any cylinder-piston unit is brought about directly and all work spaces 13 are equipped with corresponding safety valves.
- the individual adjustment paths of these closures can be roughly specified by determining the diameter ratios, and the poppet valves can be used to fine-tune the details by adjusting the path of the plunger by adjusting the cylinder base to the poppet valve.
- the reference circuit of the push-open valves makes a new adjustment. A displacement of the piston due to leaks is thus remedied by re-adjustment after the changeover process has taken place.
