    Remote controlled (RC) section occupancy at a railroad with B-relay.
    This invention relates to the simulation of a section occupation of a railroad with security relays (so-called B-relays), in particular relays that are applied at security level in the control and control of points or crossings or used for track occupancy notification, such as a so-called occupancy notification track repeat relay (TPR relay). A security relay is an essential relay (in English: vital relay).
    A protection relay (also known as a B relay) is a relay with a safety function in a railway protection installation (including NX protection). B relays have a very high degree of reliability, and will last for decades, provided they are regularly overhauled. Important characteristics of B-relays are that they are guaranteed to fall off when the coil is de-energized and that the break contacts (in jargon back contact) open before the make contacts (front contact) are closed. There are various types of B relays, with specific characteristics. The most commonly used type is the 56001-783Grl. This relay has two coils that operate on 12V DC, four changeover contacts (whole contacts), two make contacts and a break contact. Furthermore, there are B-relays that come on with a delay, fall-off, are suitable for large currents, etc. Another type of B relay is the track relay (TR). This relay is part of a track current loop, and runs out if a track section is unoccupied, and drops out if the track section is occupied by a train. In the case of B-relays, in particular the B2 of relays (the track relay), use is often made of a movable element (in the case of the B2 relay the vane, or the vane) that is sensitive to magnetism and a resetting force, for example gravity, so that when the magnetic field generated by the one or more coils of the B-relay fails, this element is no longer present and a deflected position is retained by the magnetic field and moves by the resetting force, such as gravity, whereby the B-relay switches. A so-called BL relay is usually equipped with a return spring.
    A protection relay is supplied from the factory in a sealed housing. The rear wall of the housing is equipped with contact ports corresponding to contact plugs (so-called terminals) that protrude from a contact block (so-called plugboard) in the relay box. A Brelais is placed by pressing its rear wall against the contact block so that the terminals are inserted into the contact ports so that the B relay, via wires connected to the terminals, is galvanically connected to the relevant circuit in which the B relay must be included. If, after being delivered, the housing is modified or damaged by the factory or the seal is broken, the relevant product will be rejected.
    In order to be able to work safely on a railway section (for example repairing a damaged rail), it must be guaranteed that train traffic in the relevant section is blocked. For this purpose, it is known to use a so-called short-circuit lance (see e.g. EP 0847339 and EP2067650) in the relevant section, with which the presence of a train in this section is simulated. This generates a track occupancy notification with the result that the next train is not allowed in this section by the train protection. However, placing a short-circuit lance is cumbersome and time-consuming and dangerous.
    In a first aspect, the object of the invention is to improve the controlled curdling of a track section, preferably while avoiding the use of a short-circuit lance.
    In connection with this first aspect, it is proposed that the B relay associated with the track occupancy notification of a section (that is, the B relay that drops out as soon as a train enters the section or a short-circuit lance is placed that simulates a train in the section) to rest or associate with a switch which is preferably associated with or provided with a transmitter and / or receiver for wireless communication and is arranged such that upon receipt of a suitable wireless signal (or by suitable operation, e.g. manually) the switch is switched in a first or second switching position in which the switch causes the B relay to fall off or has no influence on the functioning of the B relay. The switch can optionally take one or more further switch positions. To release the B relay, the switch interrupts, for example, the power supply of the B relay, for example, a power supply wire connected to the B relay, eg 12V DC or 110V AC.
    The switch is preferably located on or in close proximity to the frame on which the B relay is mounted. The switch is more preferably located on, in or on a so-called adapter or intermediate piece against which the rear side of the B relay is placed. Applying an adapter offers the possibility of quickly converting an existing situation in, for example, a relay box or relay house. Preferably, an intervention within the housing of the B relay is avoided, more preferably the housing of the B relay remains unaffected.
    The adapter or the adapter is a separate component and is located behind the B relay, for example, is preferably enclosed, between the housing of the B relay and the contact block and preferably has a width and height substantially equal to that of the housing of the B relay.
    In a second aspect, the object of the invention is to rapidly convert an existing application of a B relay in, for example, a relay box or relay housing. This second aspect forms an invention independent of the first aspect, which may optionally be combined with the first aspect.
    In connection with this second aspect, an adapter or intermediate piece, being a separate part, is provided and is located behind the B-relay, for example, is preferably enclosed, between the housing of the B-relay and the contact block and has at preferably a width and height substantially equal to that of the housing of the B relay. The adapter may be equipped with the aforementioned switch and / or another feature related to the function of the B relay, such as a galvanic coil.
    For the interior space of the housing of the B relay, one or more of the following preferably applies: is a single interior space; contains one or more of a single or double galvanic magnet coil with preferably soft-iron core, an anchor, a return spring of the anchor, or the anchor designed or equipped with a so-called vane in which the force of gravity, instead of a return spring, is the return force to displace the magnetic field by switching off the magnet coil, supplies the anchor in the other position, a changeover contact, a make contact, a break contact; contains all components of the B relay; is hermetically sealed with respect to the environment; is sealed against unauthorized access; has a boundary wall that is transparent to visible light; at least one or two, preferably mutually parallel and / or straight, mounting sleeves extend therethrough, sealed relative thereto, and culminating through the two opposite end wall walls, so that in a mounting sleeve a mounting pin protruding on either side can be plugged in (in a relay box a pair of mutually parallel, fixed mounting pins is available for each B-relay on which a B-relay housing is simply inserted so that its rear wall is placed against the contact block and then nuts are turned on the out of the front wall of the B-relay housing protruding wire ends of these mounting pins so that the B-relay housing remains slidably on the mounting pins); one or more galvanic conductors protruded through a boundary wall into the environment from this space; only one or more galvanic conductors extend from the space into the environment; the galvanic conductors are galvanically connected to one or more components in this space, such as a magnetic coil or a switch contact; contains a direction sensitive relay.
    The switch and / or other device is preferably located between the rear wall of the B relay and the contact block, for example inside the adapter.
    Preferably, the rear wall of the B relay includes rearwardly projecting contact members, for example pins in a pattern corresponding to the pattern of forward-facing, preferably complementary, contact members, such as holes on the front wall of the contact block, so that these members can be mutually galvanically connected, for example the contact pins can be inserted into the contact holes by pressing the B relay backwards against the contact block in the horizontal direction. The adapter preferably has contact holes similar to the contact block on its side facing the B relay and contact pins similar to the B relay on its side facing the contact block. Alternatives to the contact pins and holes are also conceivable, or the reverse situation.
    The switch is preferably equipped with a plurality of contacts, with mechanical means ensuring that the positions that these contacts can take are always in a fixed, predictable relationship to each other. This allows the safe functioning of the switch to be monitored. For this purpose, the switch is, for example, equipped with a primary and a secondary contact. The primary contact is arranged for canceling or adjusting the power supply, for example interrupting or making the circuit, of the B-relay, the secondary contact monitors the position of the primary contact. The primary and secondary contact are combined with each other by mechanical means such that when the primary contact is open, the secondary contact is closed, and vice versa. To achieve a blockage, the switch is operated so that the primary contact goes from closed to open (or vice versa), whereby the power supply of the B relay is canceled or adjusted, for example the circuit of the B relay is interrupted or closed. At the same time, the secondary contact is closed so that a control circuit is closed through which a control current flows, which is an indication that the circuit of the B relay is interrupted and therefore the associated section is blocked.
    The adapter is preferably equipped with mounting pins protruding at the front and / or rear, on which the B-relay and / or the contact block can be mounted. Alternatively, the adapter includes mounting sleeves to mount the adapter on mounting pins protruding from the contact block. The adapter is preferably substantially plate-shaped.
    Starting from the existing situation, the contact block, or front face thereof, is preferably moved backwards, for example by exchanging the existing contact block for another contact block. This displacement to the rear is preferably substantially equal to the distance over which the front side of the B relay would come forward through the intermediate placement of the adapter and is therefore generally substantially equal to or determined by the thickness of the adapter . This displacement is preferably at least 10 or 25 or 40 or 60 millimeters. This prevents the B relay from coming (too far) through the adapter insertion. If the B relay (too far) came forward, a closing door in front of the B relay could, for example, no longer be closed.
    The rearward displacement is preferably carried out without replacing the existing contact block and / or the contact block is mounted on the suspension frame via the adapter.
    The rearward displacement is preferably carried out as follows: The attachment of the existing contact block to the suspension frame located behind it is canceled, whereafter the now loose contact block is placed behind the suspension frame. The adapter can be placed entirely in front of or entirely behind the suspension frame, preferably the front part is behind and the rear part behind the suspension frame.
    The usual mounting pins on the contact block are preferably removed, or possibly replaced by longer ones. In the case of longer specimens, they protrude through the adapter and through the B relay and a little further in front of the B relay, as is customary with a B relay that is directly on the contact block, ie without the intervention of the adapter. mounted. The adapter is preferably equipped with mounting pins that preferably protrude only from the front and / or on which only the B relay is plugged. Preferably the contact is attached to the adapter with screws or bolts.
    Preferably, the front of the adapter, that is, the side facing the B relay, has an embodiment in shape and contact plugs that allow the B relay to be electrically and / or mechanically coupled to the adapter; and / or the rear of the adapter has a form and contact ports that allow the contact block to be electrically and / or mechanically coupled to the adapter such as in a manner known per se that the B relay is electrically and mechanically coupled to the contact block . Preferably, the front of the adapter is identical to the front of the contact block and the rear of the adapter is identical to the rear of the B relay.
    The adapter is preferably mounted permanently, in other words it stays at least one week or month or year between the B relay and the contact block.
    The adapter offers the advantage that wiring in the vicinity of the B relay does not have to be changed and / or disconnected

    FIG. 1 shows the block-shaped relay housing 1 which hermetically closes a single internal space from the environment. At a high level, two parallel, straight mounting sleeves 2 run through the interior and protrude through both end walls. These mounting sleeves are sealed with respect to the internal space. A mounting pin longer than the sleeve can protrude from the sleeve at both sleeve ends.
    The internal space contains all components of the B relay, of which only the magnet coil is shown. This is at a low level. This magnet coil switches the relay and is located at the bottom of the B relay.
    Fig. 1 also shows an adapter plate 3 and a contact block
    4. From the contact block 4 (as usual) place the two mounting pins (not visible in fig. 1) on which the adapter plate 3 and the B relay 1 are mounted (the mounting pins stick into the mounting sleeves 2). These mounting pins, which are extended from the prior art, are rigidly fixed on the contact block 4 and protrude perpendicularly from the contact block, extending substantially horizontally. The adapter plate 3 carries the switch with associated wireless receiver for remotely wirelessly switching the B relay between on and off to simulate a train occupation. Furthermore, the adapter plate carries contact points in the pattern matching the contact block and the B relay so that the contact block and B relay experience the facing side of the adapter plate as the relevant side of the B relay (ie rear wall of the B relay), respectively contact block.
    B relays are available, for example, from Alstom Signaling Inc., West Henrietta, NY, USA (www.alstomsignalingsolutions.com).
    FIG. 2 shows the block-shaped, hermetically sealed relay housing (made of transparent plastic, excluding the rear wall 16) and now also most components of the B relay (type B1) inside this relay housing, including: a galvanic magnet coil with soft-core core, an anchor, a return spring of the anchor, a changeover contact, a make contact, a break contact. The mounting sleeves are also visible. The B relay is mounted on a contact block 4. FIG. 8 shows a B2 type B relay.
    FIG. 3-5 show a possible embodiment of the invention and give a better representation of the adapter 3 or the adapter located between the relay housing 1 and the contact block 4 and which is equipped with the wireless remote-controlled switch according to the invention. Modifications to the relay and / or contact block are therefore unnecessary.
    The front side of the adapter 3, that is to say the side facing the B relay 1, has an embodiment in form and contact plugs that allows the B relay 1 to be electrically and mechanically coupled to the adapter 3 and the back of, respectively. the adapter 3 has an embodiment in shape and contact ports that allows the contact block 4 to be electrically and mechanically coupled to the adapter 3 in the manner known per se that the B relay 1 is electrically and mechanically coupled to the contact block 4. Preferably, the front side of the adapter 3 is identical to the front side of the contact block 4 and the rear side of the adapter 3 is identical to the rear side of the B relay.
    The adapter 3 shown in Figs. 3-5 is equipped with mounting pins 5 which replace the usual mounting pins on the contact block 4. The mounting pins 5 are permanently fixed to the adapter 3 and protrude from the adapter 3 on its side facing the relay 1. For the purpose of mutual mounting, these pins 5 protrude into the mounting sleeves 2 of the relay
    1. Mounting pins 6 protrude from the adapter 3 on its side facing the contact block 4 and are inserted into mounting sleeves 7 of the contact block 4 for mutual mounting. In an alternative, the pins 6 and the sleeves 7 are missing.
    The adapter is equipped with lips 8 for mounting by fixing means (not shown) to the contact block 4.
    FIG. 5 shows the adapter 3 equipped with two galvanic coils and the switch. The coding holes 20 on the relay 1 are also visible (see also Fig. 4).
    FIG. 6 shows the per se known mounting of the contact block 4 on the support frame 11 via the lips 19. The B relay is plugged onto the pins protruding from the contact block and is pressed against the contact block 4 by placed on the free end of the pins nuts 9 or similar retaining members.
    FIG. 7 shows the situation when starting from FIG. 6, the contact block 4 is moved backwards to provide space for the adapter 3 without the B relay moving further forward. The adapter 3 is now coupled to the support frame 11 with a lip 10 and carries on its rear side the contact block 4 and on its front side the B relay 1. The contact block 4 has been stripped of the pins 5, the adapter 3 is now equipped with pins 5 on which the B relay is plugged. The lips 19 are not used.
    FIG. 9 shows the usual electrical plug connection between the B relay and the contact block 4. The arrow A indicates the direction in which the plug connection is made or disconnected by moving the housing 1 and the contact block 4 in the direction of the arrow relative to each other. At the rear of the rear wall 16 of the relay there are contact ports, each of which is formed by a respective pair of contact lips 15 (prongs) protruding from the rear wall 16. Each contact port 15 fits an associated contact plug provided by an electrically insulated wedge-shaped pin 12 protruding from the front of the contact block 4. The pin 12 has an upper contact (top terminal) 13 and a lower contact (bottom terminal) 14, each of which has its own electrical wire 17 connected. The electrical wires 17 protrude from the rear of the contact block 4. Each contact lip 15 is electrically connected to its own relay contact 18 located inside the housing 1 and mounted on the front of the rear wall 16. The contact lips 15 are resiliently biased towards each other and are pushed away from each other by the pin 12 so that they clamp the pin 12 elastically resiliently between them. One contact lip 15 makes electrical contact with the upper contact 13, the other contact lip 15 makes electrical contact with the lower contact 14. The electrical currents from the relay contacts 18 to the wires 17 are thus electrically isolated from each other.
    FIG. 10 shows a per se known contact block 4 with the pins 5 on which the relay is plugged in, and the contact plugs 12. The contact plugs 12 are arranged in three (at least two) horizontal rows and three (at least two) vertical columns.
    FIG. 13-15 show an embodiment of the adapter 3. FIG.
    shows the coding pins 21 which prevent a relay 1 without coding holes 20 or with coding holes 20 from being mounted in a different pattern on the contact block 4 or the adapter 3. The adapter 3 comprises a plate 22 which mimics a contact block 4. This plate 22 is mounted on a box-shaped body 23. In Fig. 15, the plate 22 is removed so that the inside of the body 23 is visible.
