[0001] DESCRIPTION

[0002] Monitoring switch device for monitoring a control valve operating state and monitoring device with such a monitoring switch device

[0003] Monitoring switch device for monitoring a control valve operating state of a control valve and monitoring device with such a monitoring switch device.

[0004] Control valves are used, for example, in pneumatic braking systems for rail vehicles to supply the appropriate brake cylinder pressure to the brake cylinders. The control valves include a mechanism for switching the control valve operating state from a P position for passenger transport to a G position for freight transport, and vice versa. In the P position, the air passages in the control valve are throttled less than in the slower-acting G position. The mechanism also controls the brake activation and release according to specified standards for the respective transport operation.

[0005] Monitoring the operating status of the control valves or the mechanism responsible for switching is currently performed via local, physical inspection of the control valves. Since a rail vehicle, especially in long trains or train sets, contains a large number of control valves, this manual inspection of the operating status of the control valves is time-consuming and therefore costly. Furthermore, manual inspection is prone to errors, especially with a large number of control valves, as attention can lapse during longer inspections and / or control valves can be overlooked.

[0006] The problem described above can also affect other areas of application of control valves that have different control valve operating states in different operating modes according to a corresponding mechanism for switching the control valve operating state. In view of the above, it is therefore an object of the present invention to provide a control valve operating state monitoring system that is improved compared to the prior art.

[0007] This problem is solved by the subject matter of the independent claims. Advantageous further developments are the subject matter of the dependent claims.

[0008] According to the invention, a monitoring switch device for monitoring a control valve operating state of a control valve comprises a control valve switching lever configured to be movable at least into a first position corresponding to a first control valve operating state, a switch switching device formed together with the control valve switching lever or operatively connected to the control valve switching lever to be moved together with the control valve switching lever, and a switch device comprising at least one first switch switchable by the switch switching device when the control valve switching lever is in the first position.

[0009] The monitoring switch device is accordingly a device for monitoring a control valve operating state of a control valve having at least one first switch. The control valve operating state can be monitored based on the switching state of the at least one first switch. The at least one first switch can be designed as a normally open contact, or normally open contact, so that it indicates the reaching of the first position and thus the first control valve operating state when an electrical circuit is closed. Alternatively, the at least one first switch can be designed as a normally closed contact, or normally closed contact, which indicates the reaching of the first position and thus the first control valve operating state when the electrical circuit is interrupted. The term "switchable" or "switching" can thus encompass both the closing and opening of an electrical circuit.The following description assumes a normally open contact as the at least one first switch, whereby the description contents are equally applicable in a correspondingly reversed form with regard to reaching the first position, unless this is excluded due to the reverse principle. The description of the design of the first switch is also applicable to the second switch described below. The control valve operating state relates to a control valve switching position and / or control valve actuation that corresponds to a basic configuration setting of a control valve. Within the scope of the basic configuration setting, a fluid flowing through the control valve can still be adjusted, although a transmission behavior characterizing the operating state is determined by the basic configuration.With reference to an exemplary pneumatic braking system of a rail vehicle, the first control valve operating state may correspond to a basic configuration in which the air passages in the control valve are throttled less than in another control valve operating state. Alternatively or additionally, the basic configuration may also refer to the times and / or durations of brake activation and / or brake deactivation.

[0010] The at least one first switch is switched by moving the control valve switching lever into the first position. The movement of the control valve switching lever corresponds to a switching operation of the control valve into the first control valve operating state by a corresponding control valve switching mechanism. The control valve switching lever is thus a lever whose movement corresponds to a switching of the control valve. For this purpose, the control valve switching lever can, for example, be directly or indirectly mechanically connected to the control valve switching mechanism or even form the control valve switching mechanism, so that the control valve switching lever not only switches the first switch but also the control valve operating state.

[0011] To switch the at least one first switch, a switch switching device is provided which is formed together with the control valve switching lever or at least operatively connected thereto. The switch switching device is thus moved together with the control valve switching lever. The design of the operative connection refers to the fact that the switch switching device is not formed integrally with the control valve switching lever, but rather the joint movement occurs according to a direct or indirect connection. The indirect connection can, for example, contain bridging elements and / or transmissions so that, for example, comparatively large movements of the control valve switching lever can be implemented with respect to comparatively smaller movements of the switch switching device. Furthermore, the switch switching device can be provided in an interchangeable manner thanks to the connection, in contrast to an integral design.This not only refers to easier replacement due to wear or other damage, but can also affect replacement due to different transmission behavior. By designing the switch switching device together with the control valve shift lever, the influence of manufacturing tolerances can be reduced, at least compared to combining separate components.

[0012] The configuration described above thus enables direct and automatically detectable monitoring of at least a first control valve operating state by simultaneously switching the at least one first switch together with the switching of the control valve into at least a first control valve operating state.

[0013] In one embodiment, the control valve switching lever is further movable into at least one second position corresponding to a second control valve operating state, and the switch device has at least one second switch that can be switched by the switch switching device when the control valve switching lever is in the second position.

[0014] Accordingly, the achievement of at least two control valve states can be monitored. The control valve switching lever can be configured to be bidirectionally movable between the first position and the second position. Alternatively or additionally, a movement from the first position to the second position or vice versa, and thus a switching of the first switch and the second switch, can also be unidirectional.

[0015] In particular, the switch switching device is arranged between the first switch and the second switch.

[0016] Due to the arrangement between the first switch and the second switch, the switch switching device can switch the respective switches with comparatively short switching paths, as only a bidirectional movement of the switch switching device can occur. In particular, the first switch and the second switch are located opposite each other.

[0017] For example, starting from an axis of symmetry from which the first and second switches are equidistant in a direction perpendicular to the axis of symmetry, the switch switching device can thus switch the first or second switch over equal distances. Regardless of the switching distance, the opposing arrangement of the first switch and the second switch can also simplify the switch switching device kinematics and design required for switching. This also applies to the control valve switching lever.

[0018] In one embodiment, the first switch and / or the second switch is / are a mechanical switch, in particular a microswitch, and the switch switching device has at least one switch switching element which is designed as a control gate for switching the first switch and / or the second switch.

[0019] The mechanical switch has, for example, a switch arm that is closed by the movement of the control valve switching lever into the first position and thus the movement of the switch switching device in the case of the switch as a normally closed contact. For this purpose, the switch switching device is designed as a control gate so that the switch is closed depending on the position of the switch switching device relative to the switch arm. The switch arm can be closed directly via the switch switching device or have a switching section facing the switch switching device that can come into contact with the switch switching device. Additional intermediate elements for bridging and / or gear ratio adjustment can also be provided between the switch switching device and the switch arm.

[0020] The control gate thus serves as a contour element, with the contour changing the distance between the switch arm and a contact section of the switch to close the switch, at least in sections, during a relative movement between the switch arm and the switch switching element. The contour section, which reduces the distance between the switch arm and the contact section to such an extent that the switch is closed, thus forms a switch switching section. However, the term "switch switching section" is not limited to the use of a control gate, but can also be designed differently with regard to other switching principles. In general, the switch switching section forms the section of the switch switching device intended for switching a respective switch.

[0021] If the first switch and the second switch are designed as mechanical switches, the control gate can have two switch switching sections in order to switch the respective switch by a respective switch switching section upon movement. Specifically, when the control valve switching lever is moved into the first position, the first switch can be closed by the corresponding movement of the first switch switching section into a position in which the first switch arm of the first switch contacts a contact section of the first switch. The switch switching device or the control gate is designed such that the second switch switching section does not switch the second switch when the first switch is switched by the first switch switching section.In other words, the switch switching device is designed with a respective first switch switching section and second switch switching section such that the first switch switching section switches the first switch when the control valve switching lever is in the first position, and the second switch switching section switches the second switch when the control valve switching lever is in the second position. As already explained, the principle of using normally open contacts can also be applied to normally closed contacts, wherein reaching the first and / or second position is then represented not by a closed contact, but by an open contact. The switch principle as normally closed or normally open contact of the first switch and the second switch can also be different.

[0022] Instead of a first switch switching section for the first switch and a second switch switching section for the second switch, only one switch switching section can be provided for switching the first switch and the second switch. This is independent of the switch's design as a mechanical switch and can also apply to other switching configurations, as described below. By using only one switch switching section, it can be ensured that only one of the switches is switched at a time. However, using two switch switching sections can shorten the distances required for switching between the first switch and the second switch.

[0023] The use of a microswitch as the first and / or second switch can enable miniaturization of the switching device.

[0024] In one embodiment, the first switch and / or the second switch are / are designed as a magnetic switch or electrical contact, and the switch switching device comprises at least one switch switching element with at least one switch switching section. In the case of the magnetic switch, the magnetic switch can be closed via the at least one switching section. In the case of the electrical contact, the at least one switch switching section forms a counter contact in order to be connectable to the electrical contact as a circuit.

[0025] In the case of the first switch and / or the second switch being designed as a magnetic switch, the switch switching section can be designed, for example, as a permanent magnet or have a permanent magnet whose magnetic field, when positioned accordingly, closes the respective contact, i.e., for example, contacts the switching arm of the first switch with the contact section of the first switch when the control valve switching lever is in the first position, and contacts the switching arm of the second switch with the contact section of the second switch when the control valve switching lever is in the second position.

[0026] If an electrical contact is formed, the switch switching device forms part of the first and / or second switch via the at least one switch switching section. In other words, the at least one switch switching section forms a counter contact via which the electrical circuit in which the first and / or second switch is provided can be closed. The term counter contact encompasses both embodiments in which the electrical circuit is then further conducted via the switch switching device and embodiments in which the switch switching section connects two contact sections of the respective switch. The switching principles can be combined with one another. For example, to switch the first switch and / or the second switch, the switching section assignable to this switch can be designed as a control gate, which additionally contains a permanent magnet or is designed as such.This allows the movement of a corresponding switch arm to be supported or supplemented by the switch switching section. For example, the switch arm can first be moved mechanically and then finally contacted with the switch contact section via the magnetic field. Such a combination can also compensate for manufacturing tolerances that result, for example, in a residual gap between the switch arm and the contact section.

[0027] However, the different switching principles can also be different for the first switch and the second switch.

[0028] In one embodiment, the switch device comprises a switch device housing with a switch device housing opening. The switch switching device protrudes at least partially through the switch device housing opening into the switch device housing in order to switch the first switch arranged in the switch device housing and / or the second switch arranged in the switch device housing.

[0029] The first switch and / or the second switch can thus be protected from external influences by the switch device housing.

[0030] In particular, the switch device housing opening forms at least one stop for the switch switching device, so that the switch switching device cannot be moved beyond the first position in a first direction of movement and / or cannot be moved beyond the second position in a second direction of movement.

[0031] For example, the switch device housing opening can be designed as a circular segment, wherein the boundaries of the circular segment in the circumferential direction limit the movement of the switch switching device in the switch device housing opening and thus function as two stops. Abutment of the switch switching device against the first stop corresponds to the first position of the control valve switching lever, in which the first switch is to be switched by the switch switching device. If the control valve switching lever is moved in an opposite direction into the second position, the circular segment represents this second position via the second stop, and the switch switching device switches the second switch when it rests against the second stop.

[0032] The at least one stop can also be formed by a different shape of the switch device housing opening or by shaped elements attached thereto. In alternative embodiments, the switch device housing can also have stop elements that are independent of the switch device housing opening.

[0033] Conversely, by using at least one stop, the movement of the control valve switching lever can also be limited, thus also supporting the positional retention of the control valve for a corresponding control valve operating state. This particularly applies to configurations in which the control valve switching lever is simultaneously designed as a mechanism for switching the control valve or is at least in a fixed positional relationship to the mechanism for switching the control valve.

[0034] In one embodiment, a movement of the control valve switching lever, in particular a rotational movement of the control valve switching lever, can be transferred into a rotational movement of the switch switching device.

[0035] The rotary movement of the switch switching device can, for example, occur around an axis that is substantially perpendicular to a switching movement of the first and / or second switch. The rotary movement of the switch switching device via a rotary movement of the control valve switching lever, in particular pivoting the control valve switching lever about a rotational axis parallel to the switch switching device, results in a simple implementation of the monitoring switching process. Alternatively, however, translational movements can also be used for the control valve switching lever and / or the switch switching device.

[0036] In one embodiment, the monitoring switch device is configured to transmit a signal when the first switch and / or the second switch are / are switched. As described above with regard to the configuration of the first and / or second switch as a normally open or normally closed contact, the signal can represent a closed or open contact. The signal transmission can be limited to the signal which, in the case of the first switch, corresponds to the first position of the control valve switching lever, i.e. the first switch is switched. In addition, however, a signal transmission can also be provided which additionally indicates the case in which the first switch is not switched. This equally applies to the signal transmission for the second switch. If the first switch and the second switch are provided, the comparison of the signals can also be used for a plausibility check.For the purposes of a plausibility check, the case in which the signal transmission indicates that both the first and second switches are switched is considered a fault. This can then trigger an alarm or initiate other fault-correcting action.

[0037] The signals can be transmitted to a signal acquisition unit, which can be part of the monitoring switch device. However, the signal acquisition unit can also be part of a monitoring device described below or a higher-level unit. For example, when monitoring a control valve of a rail vehicle, a higher-level signal acquisition unit can be provided that acquires the signals from several monitoring switch devices installed in the rail vehicle.

[0038] The signal transmission can, for example, be used for control purposes and / or displayed optically and / or acoustically.

[0039] In one embodiment, the first switch and / or the second switch are / is arranged on a mounting plate.

[0040] The mounting plate allows the positional relationship of the first and / or second switch to the switch switching device to be easily specified. The mounting plate can be provided alternatively or additionally for simple attachment to a control valve device, in particular a control valve device housing. If the switch device has a switch device housing, the mounting plate can be formed over the switch device housing or connected to it.

[0041] In a further aspect, the present invention relates to a monitoring device for at least one control valve device. The monitoring device comprises the at least one control valve device with at least one control valve and at least one monitoring switch device as described above. The control valve switching lever can be moved into the first position and / or the second position when the at least one control valve is switched to a predetermined control valve operating state.

[0042] In particular, in this configuration, the control valve switching lever also forms the mechanism for switching the control valve into the at least one control valve operating state.

[0043] In one embodiment, the at least one monitoring switch device is attached to the control valve device.

[0044] This can be done via the mounting plate described above or the switch device housing.

[0045] In one embodiment, the monitoring device is provided for monitoring a control valve operating state of a rail vehicle, and the first position corresponds to a control valve operating state for passenger transport, and / or the second position corresponds to a control valve operating state for freight transport.

[0046] Accordingly, a manual check of the control valve operating states for passenger transport or freight transport can be easily implemented through automated testing via the respective monitoring devices. If there are multiple monitoring devices or multiple monitoring switch devices, depending on the design of the rail vehicle, the signals from the monitoring switch devices are preferably transmitted to a central signal acquisition unit or a central unit superordinate to individual signal acquisition units in order to centrally monitor control valve operating states. In particular, control valve data is assigned to the signal transmission in order to locally assign the signals from individual control valves.

[0047] The features described in the above description of the monitoring switch device are equally applicable to the monitoring device. Likewise, features described for the monitoring device are transferable to the monitoring switch device, unless they have already been described for this purpose.

[0048] In a further aspect, the present invention relates to a rail vehicle with a monitoring switch device described above and / or a monitoring device described above.

[0049] The features described in the above description of the monitoring switch device and the monitoring device are equally applicable to the rail vehicle. Likewise, features described for the monitoring switch device and the monitoring device for the rail vehicle are transferable to the latter, unless they have already been described for this purpose.

[0050] Exemplary embodiments of the present invention are described below with the aid of the accompanying drawings.

[0051] In detail,

[0052] Fig. 1 is a schematic representation of an exemplary embodiment of a monitoring device with a monitoring switch device according to the present invention;

[0053] Fig. 2 is a schematic sectional view of a first exemplary embodiment of a switch device and a switch switching element for a monitoring switch device according to Fig. 1; Fig. 3 is a schematic sectional view of a second exemplary embodiment of a switch device and a switch switching element as an alternative to a switch device and a switch switching element for a monitoring switch device according to Fig. 1;

[0054] Fig. 4 is a schematic sectional view of a third exemplary embodiment of a switch device and a switch switching element as a further alternative of a switch device and a switch switching element for a monitoring switch device according to Figure 1;

[0055] Fig. 1 shows a schematic representation of an exemplary embodiment of a monitoring device 50 with a monitoring switch device 30 according to the present invention. The monitoring switch device 30 comprises a switch device 2 with a first switch 21 and a second switch 22 (Fig. 2), a control valve switching lever 3, and a switch switching device 4. The switch switching device 4 is connected to the control valve switching lever 3 at one end and extends perpendicular to an extension direction of the control valve switching lever 3 in the direction of the switching device 2 in order to switch the first switch 21 or the second switch 22, as described below. The signals corresponding to the switching of the first switch 21 and the second switch 22 are transmitted from the switching device 2 via a signal line 5 to a signal acquisition unit 60.

[0056] The monitoring device 50 also comprises a control valve system 10 with a control valve device 1 having a control valve 1a. In the present embodiment, the control valve 1a is a control valve of a pneumatic braking system for a rail vehicle, which can be switched into a control valve operating state for passenger transport and a control valve operating state for freight transport. The mechanism for switching the control valve 1a into the different control valve operating states is formed here by the control valve switching lever 3, which is correspondingly connected to the control valve 1a. In the present embodiment, the control valve switching lever 3 thus serves both as a mechanism for switching the control valve 1a and as a control valve switching lever for switching the first switch 21 and the second switch 22 depending on the selected control valve operating state.

[0057] For the control valve operating state for passenger transport, the control valve switching lever 3 is to be moved such that the control valve switching lever 3 rotates into a first position, so that the switch switching device rotates together therewith into a position in which the first switch 21 is switched. For the control valve operating state for freight transport, the control valve switching lever 3 is in turn to be moved such that the control valve switching lever 3 rotates into a second position, so that the switch switching device rotates together therewith into a position in which the second switch 22 is switched. Through the corresponding signal transmission, the control valve operating state can be displayed via the signal acquisition unit 60.In alternative embodiments, the control valve system 10, in addition to or alternatively to the control valve device 1, comprises control valve devices that are designed to switch, for example, the control valve operating states "on" or "off" or the control valve operating states "empty" or "loaded" of the control valve 1a by means of the control valve switching lever 3. Such control valve devices can also be monitored, analogously to the control valve device 1, by means of switches that perform the functions of the first switch 21 and the second switch 22.

[0058] Fig. 2 shows a schematic sectional view of a first exemplary embodiment of a switch device 2 and a switch switching element 4a for a monitoring switch device according to Figure 1. The switch element 2 has a switch device housing 2a with a switch device housing opening 2b through which the switch switching device protrudes at least partially into the switch device housing 2a from the outside in order to be able to switch the first switch 21 and the second switch 22. The switch switching element 4a thus refers to the part of the switch switching device 4 that protrudes into the switch device housing 2a and is provided for switching the first switch 21 and the second switch 22. The switch switching element 4a is designed as a control gate with a first switch switching section 41a for switching the first switch 21 and a second switch switching section 42a for switching the second switch 22.The switch device housing 2a also serves as a mounting plate for mounting the first switch 21 and the second switch 22 and attaching them to the control valve system, here a housing of the control valve device 1.

[0059] The first switch 21 and the second switch 22 are designed as mechanical switches, specifically microswitches. The first switch 21 thus comprises a switch arm 21a and a contact section 21b. To move the switch arm 21a into a closed position in contact with the contact section 21b, the switch arm 21 has, at its end intended for contact, a switching section 21aa facing the switch device housing opening 2b, which is curved outwards to facilitate engagement with the first switch switching section. In alternative embodiments, the switching section 21aa can be shaped differently or even omitted. With respect to the rotational axis of the switch switching element 4, which runs perpendicular to the control valve switching lever 3, the first switch 21 and the second switch 22 are arranged opposite one another. The second switch 22 has a structure analogous to the first switch 21.Accordingly, the second switch 22 also includes a switch arm 22a with a switching section 22aa and a contact section 22b. The first switch 21 and the second switch 22 are arranged opposite each other such that the respective switching arms 21a and 21b face each other. The first switch 21 and the second switch 22 are configured as normally open contacts, so that they interrupt an electrical circuit in a state in which the respective switching arm 22a, 22b is not moved by the respective switch switching section 41a, 42a.

[0060] The operation of the monitoring device 50 results from the configuration described above as follows. If the control valve 1a is moved into a control valve operating position for passenger transport via the control valve switching lever 3, the control valve switching lever 3 simultaneously moves into a first position. In the present embodiment, the first position corresponds to a position in which the concurrently moved switch switching device 4 is moved into a rotational position in which the first switch switching section 41a of the switch switching element 4a brings the switching arm 21a of the first switch 21 into contact with the contact section 21b of the first switch 21 via the switching section 21aa. The switch switching element 4a is designed here as a circular segment that projects into a circular switch device housing opening 2b.The circular segment is configured such that the switch switching element 4a is smaller in the circumferential direction from the first switch switching section 41a to the second switch switching section 42a than the circumferential section of the switch device housing opening 2b from the switching section 21aa of the first switch 21 to the switching section 22aa of the second switch 22. In other words, with a distance of approximately 180° between the switching sections 21aa and 22aa along the circumference of the switch device housing opening 2b, the circular segment is smaller than 180° to prevent the switch switching element 4a from switching both the first switch 21 and the second switch 22 simultaneously.

[0061] When the first switch 21 is closed by the movement of the control valve switching lever 3 into the first position and thus the corresponding movement of the switch switching element 4, an electrical signal is transmitted to the signal transmission unit 60 and the control valve operating state for a passenger transport is displayed.

[0062] If, due to a change in use of the rail vehicle, the control valve operating state for freight transport is to be switched, the control valve switching lever 3 is moved to a second position, which triggers this operating state. By moving to the second position, the switch switching element 4a is rotated about its axis of rotation into a position in which the second switch 22 is switched via the second switch switching section 42a. The rotational movement of the switch switching element 4a for the second position occurs in a direction opposite to the direction of rotation in the first position. In other embodiments, in particular with only one switch switching section, a direction of rotation in the same direction can be provided alternatively or additionally.

[0063] Fig. 3 shows a schematic sectional view of a second exemplary embodiment of a switch device 2' and a switch switching element 4a' as an alternative to a switch device and a switch switching element for a monitoring switch device according to Fig. 1. The switch device 2' of the second embodiment differs from the switch device 2 in the switch device housing opening 2b'. The switch device housing opening 2b' does not form a complete circle here, but rather a circular segment. As a result, the switch device housing opening 2b' forms two stops at the respective segment boundaries in the circumferential direction.The circular segment is dimensioned and arranged such that the first stop corresponds to a position in which the switch switching element 4a' switches the first switch 21 when it rests against the first stop, and the second stop corresponds to a position in which the switch switching element 4a' switches the second switch 22 when it rests against the second stop. The switch switching element 4a' is not designed as a circular segment with two switch switching sections, but rather as a pin arranged eccentrically to the longitudinal axis of the switch switching device 4 as an axis perpendicular to the control valve switching lever 3, which pin is bidirectionally movable between the first stop and the second stop along the circumference of the switch device housing opening 2b' when the switch switching device 4 rotates.

[0064] Fig. 4 shows a schematic sectional view of a third exemplary embodiment of a switch device 2" and a switch switching element 4a" as a further alternative of a switch device and a switch switching element for a monitoring switch device according to Figure 1. The switch device 2" of the third embodiment differs from the switch devices 2, 2" of the first and second embodiments in that the first switch 21" and the second switch 22" are designed as electrical contacts. The switching of the first switch 21" takes place in that the switch switching element 4a" comprises a first counter contact as a switch switching section 41a", which is connected to the contact section 21b" of the first switch 21" when the control valve switching lever 3 is in the first position.In addition, the switch switching element 4a" also has a second counter contact as a switch switching section 42a", which is connected to the contact section 22b" of the second switch 22" when the control valve switching lever 3 is in the second position.

[0065] The invention is not limited to the described embodiment. In particular, features described in the embodiment, other refinements, and developments of the invention described herein can be combined with one another, provided they do not reasonably exclude one another.
