Definitions
- the invention relates to a switch drive with an elongated adjusting slide.
- the invention further relates to a method for operating such a switch drive.
- the invention also relates to using a variable length adjusting slide.
- the invention can therefore relate to the technical field of rail vehicles, in particular switch mechanisms for corresponding rails.
- Switches are generally known as transition devices to enable a rail vehicle to change from one track to another.
- the actual switch (-changing) position is accomplished by a so-called switch drive.
- Switch drives have the task of changing switches, i.e. moving the switch tongues to one of two end positions (left or right, or retracted or extended).
- the switch drive usually has an axially movable throw bar which is connected to the switch tongues of the switch via an external rod.
- the throw bar must both transmit the actuating forces and also be the right length for the required actuating stroke (e.g. in the range 150-220 mm).
- the switch drive 200 has a housing 205 in which the adjusting slide 210 is mounted with a defined length.
- the adjusting slide 210 is arranged in a first position and fixed by a locking slide 250.
- the locking slide 250 can snap into a respective groove of the adjusting slide 110.
- the adjusting slide 210 can be moved axially into a second position via the retaining coupling 240, either manually or by a motor.
- the locking slide 250 also changes from a first position to a second position and defines the new end position of the adjusting slide 210 and snaps into a corresponding groove again. Because the length of the adjusting slide 210 is fixed, a relatively large installation space 206 is required.
- a switch drive which comprises: i) an elongated adjusting slide, wherein the elongated adjusting slide is designed such that the length is variably adjustable; ii) a drive device which is coupled to the elongated adjusting slide and which is designed to set the variably adjustable length to a predetermined position; and iii) a control device which is coupled to the drive device and which is designed to provide and/or determine the predetermined position.
- a method for operating a switch drive comprising: i) providing a predetermined position with respect to the length of a control slide; and then ii) variably adjusting the length of the control slide to the predetermined length by means of a mechanism.
- a use of a control slide with variably adjustable length in a switch drive is described, wherein the adjustment of the length is carried out electromechanically until an end position is reached.
- adjusting slide can refer in particular to an elongated element which can be used mechanically to move a switch tongue, in particular from a first position to a second position. While a conventional adjusting slide has a defined length and is designed, for example, as a rigid rod, the elongated adjusting slide according to the invention has a variable length. In one example, the length can be varied stepwise. In a preferred example, however, the length can be varied continuously. Various implementations of the variable length are possible, some of which are described below as examples.
- the adjusting slide has at least two parts, one with an external thread and one with an internal thread.
- the length can be varied continuously by turning the thread.
- the adjusting slide can be constructed telescopically, so that an inner part can be pushed out of an outer part (or vice versa).
- the adjusting slide can have a (rolled) push chain, whereby the length increases when unrolling or Rolling up of the push chain is varied.
- the term “drive device” can refer in particular to a device which is set up as described above To move the adjusting slide in such a way that its length is varied in a controlled manner.
- the drive device can be designed as an electric motor, which is coupled to the adjusting slide. By activating the electric motor, the adjusting slide can be lengthened/shortened via the thread, for example.
- an electric motor can trigger the telescopic displacement.
- the drive device can have a drive wheel for a push chain.
- the drive device can be configured such that the predetermined position cannot be exceeded. For example, the electric motor can be switched off when the predetermined position is reached.
- an electric motor is usually used as the drive device.
- the drive device is not limited to this; other types of mechanical power transmission can also be used as a drive, e.g. B. an internal combustion engine.
- control device can refer in particular to a device which is suitable for controlling and/or regulating the length variation of the adjusting slide via the drive device described above.
- the drive device and control device are designed separately from one another, for example as an electric motor and processor.
- spatial separation can also be possible, e.g. the control device can communicate with the drive device via radio and/or a network.
- the drive device and control device can also be installed in the same unit.
- the control device can have one or more processors and specify the predetermined position or end position of the drive device. The predetermined position can, for example, be entered or selected by an operator.
- control device can be embedded in a network, e.g. an Internet of Things (IoT) environment. Based on the data from this network, the control device can then determine the predetermined position (itself). In a further example, the control device can have artificial intelligence which can be trained to determine the predetermined position and/or to determine the time or duration of the switch setting.
- IoT Internet of Things
- the invention can be based on the idea that a switch drive can be provided flexibly and in a space-saving manner if an adjusting slide whose length is variable is used, which is extended by an (electromechanical) drive into a predetermined position, which is provided by a Control device is specified or determined.
- an adjusting slide has a certain length and is fixed in one of two end positions using specific grooves.
- variable-length adjusting slide can cover all required adjusting strokes with just one design and can therefore be used extremely flexibly.
- the control device can be viewed as a smart controller that can set the desired length of the adjusting slide (and a corresponding end position).
- the drive can make it possible for the adjusting stroke to be set without mechanical grooves in the adjusting slide.
- control device of the drive device can specify the end position by not setting any further extension of the adjusting slide, e.g. B. about the number of revolutions of the driving electric motor in a slip-free system.
- an actively adjustable slide valve can significantly reduce the installation space required for the switch drive, as the length of the slide valve can be reduced in the retracted end position. With the same connection dimensions as the current drive, the required installation space is thus reduced, so that the switch drive can be installed by more users without protruding into the clearance profile of rail vehicles or trains.
- the drive device has an electric motor and is set up to adjust the length electromechanically.
- This can have the advantage that established technology can be used directly.
- Electric motors as such are known and can be used flexibly to vary the length of the adjusting disk.
- Various couplings between the adjusting disk and electric motor can also be implemented.
- the length is adjusted mechanically or non-hydraulically.
- a motor e.g. the electric motor mentioned above
- the length can be adjusted mechanically.
- an end position can thus be reached particularly reliably and precisely.
- the term "mechanical” or “electromechanical” includes hydraulics. In the latter case, the length variation of the control slide is not achieved via hydraulics.
- the predetermined position is an end position of the elongated adjusting slide.
- the drive device and/or the control device is set up to ensure that the end position is not exceeded. This can have the advantage of increasing security.
- the drive device can block the adjusting disk at a certain length setting, so that further extension (but also shortening) is impossible.
- the drive device should provide this function. In one example, this can be implemented by stopping an electric motor. In another example, the control device controls the drive device accordingly.
- the elongated adjusting slide has: a first part and a second part along the longitudinal direction.
- the second part In a first operating state, the second part is at least partially arranged around the first part (in a transition area). In a second operating state, the second part is arranged less around the first part than in the first operating state.
- This can have the advantage that the parts of the adjusting slide can be stored in a space-saving manner (in terms of installation space) and, if necessary, extend the adjusting slide by pushing it apart can .
- Two embodiments described below include the parts of a telescopic adjusting slide and the parts of an external and an internal thread.
- the first part and the second part each have a thread.
- the first part has an external thread and the second part has an internal thread. This can have the advantage that the extension can be adjusted precisely. In addition, the end position can be safely determined.
- such a mechanism can be implemented using a driven threaded rod and an adjusting slide with a threaded hole.
- the thread can be designed to be self-locking, e.g. B. compared to the axial forces in the end position due to spring forces from the switch tongues (residual tongue tension) and transverse forces from trains passing over them.
- the extended end position is achieved by unscrewing the threaded rod and the retracted end position is achieved by screwing the threaded rod in.
- the elongated adjusting slide is designed to be telescopic.
- the adjusting slide can have a large number of parts which can be pushed into one another to save space, but can also reach a great length by being pushed apart. This embodiment can be used particularly flexibly.
- the elongated adjusting slide has a push chain.
- a push chain can both pull and push. In this way, a forward and backward movement can be generated with just one drive (e.g. a drive (gear) wheel).
- the push chain can be rolled up to save space and rolled out or in depending on the operating mode.
- an elongated element is mounted on a push chain as the adjusting slide tip.
- the adjusting slide is formed entirely from the push chain.
- the term "push chain” can refer in particular to a mechanical component of conveyor technology that can be rolled up when not under tension, but can transmit thrust and pressure forces when under tension.
- the elongated adjusting slide is essentially free of a latching area, in particular a groove.
- a locking slide is conventionally used to fix the adjusting slide in a specific end position via its grooves. According to the invention, such a blockage is preferably achieved by the drive device, so that additional effort can be saved.
- the switch drive further comprises: a housing in which the elongated adjusting slide is at least partially arranged.
- the elongated adjusting slide is arranged (substantially) in the housing at a first length setting, and wherein the elongated adjusting slide is arranged partially outside the housing in a second length setting.
- installation space can be saved because the adjusting slide practically extends out of the housing without requiring a retraction area (e.g. for a rigid rod).
- the switch drive further comprises: a sensor which is coupled to the control device and which is set up to detect at least one parameter relating to the setting of the length of the elongated adjusting slide.
- control with feedback can be operated, in particular by means of the control device.
- the control device can determine the end position and control/regulate the drive device accordingly.
- the control device can be configured to include the sensor data accordingly.
- the time of the switch setting or the duration of the switch setting can also be determined using sensor data.
- the parameter has at least one of speed, torque, actuating stroke, force, an electrical parameter, in particular one of current, voltage, power factor, power.
- control device further comprises: a communication device which is configured to carry out communication with a further control device with regard to the predetermined position and/or the parameter.
- the term "communication device” may refer in particular to a device which is designed to send and/or receive signals or data.
- the communication may be wired or wireless.
- the communication device is configured for both operating modes.
- the communication device can have one or more antennas.
- the communication device can have one or more connections (e.g. Ethernet, power cable, USB, etc.).
- the communication device can be provided as a radio transmitter/receiver.
- the communication device can be designed as a router, in particular a WLAN router.
- control device can thereby provide data or Receive instructions from other control devices and/or send them yourself.
- control device can be integrated into a network with the other control devices, e.g. B. a loT network. In this way, smart control/regulation of several switch machines or even a train station can be implemented. Modern tools such as artificial intelligence algorithms can make the evaluation of data volumes more efficient.
- the adjusting slide is mounted in a form-fitting manner, in particular in the housing of the switch drive.
- the adjusting slide can preferably be secured against unwanted rotation. This can be achieved, for example, by an n-sided outer shape with, for example, n > 2 or two parallel flattened areas of a circular base. This measure can prevent the end position from turning open, which means that the end position can be better secured.
