Abstract

The movement control device allows the main movements of the turntable ladder (2), for determining its length, inclination and pivot angle to be controlled manually, with auxiliary movements of the turntable ladder controlled automatically. The turntable ladder is provided with an auxiliary device (14), e.g. a rescue basket, with automatic control of the latter, independent of emergency control functions, with an auxiliary release device for releasing the manual control of the auxiliary device.

Description

The invention relates to a device for controlling the Movement of an aerial rescue set, such as an aerial ladder, with at least one additional device, with main movements of the aerial rescue set, such as inclination, length and Swivel angle, can be controlled manually and possible Additional movements of the aerial rescue set can be controlled automatically are and still movements of the additional devices are automatically controllable. As additional devices come rescue cage, water cannon, platform and Exceeded in question.

With an aerial rescue set, such as an aerial ladder Main movements such as turning, straightening and tilting, telescoping (Extending and retracting) the aerial rescue set manually controllable. Especially when the so-called Terrain compensation, in particular the orientation of the Rungs one in the form of a turntable ladder Lift rescue set during the ladder operation gravity-oriented takes place, this usually happens as machine-specific control, because of this the operator is relieved. The rungs become automatic aligned perpendicular to the direction of gravity. Is a Additional device, such as a rescue cage, provided As a rule, the bottom of the basket should be aligned horizontally be. To relieve the operator here too, the necessary basket leveling is also in usually carried out automatically via forced operation. This also relieves the operator.

As a rule, all automatic controls are or regulations in emergencies, if an emergency operation is made, also manually by switching off the automatic control or regulation or bypass same possible.

However, there are also normal use cases where a further manual operation is desired without an emergency operation is immediately carried out, ie certain regulations continue to be implemented automatically other, usually automatic regulations to be carried out manually, especially those of additional devices. So it can be when operating the Main rescue sentence may be necessary depending on the situation, that the basket alignment is done manually to the Aerial rescue set with the basket, for example, in one Way to lead or connect to a transfer point, as with automatic regulation of basket leveling not possible. Even if other additional devices as rescue baskets, such as water cannons, Platform, step over or the like, are present, so is their manual control outside of emergency operation desirable.

The invention is therefore based on the object To further develop the device of the type mentioned at the beginning that regardless of an emergency operation taking normal safety requirements into account manual operation of additional devices possible is.

According to the invention, the stated task is at a Device of the type mentioned above solved that exclusively assigned to the additional devices Additional release devices to release a manual Control of the same are provided.

This ensures that even with manual operation the usual active regulations of an additional device the control logic and not how this is the case with emergency operation, switched off will. The additional manual control of an additional device is detected by the fact that an additional Actuation of an unlocking or just the additional release device is made so that then a corresponding Control of the additional device is possible. The unlocked state is usually by detects a switching element, thereby targeting the automatically regulated basket leveling is switched off, all other automatic regulations are to be maintained.

In a preferred embodiment it is provided that at Release of manual control of additional movements of the lifesaving set as part of an emergency operation Emergency release facilities inevitably include a manual one Control of the movements of the additional devices can be released is.

In alternative configurations it can be provided that Movements of the additional devices within the framework of safety technology conditional restrictions are taxable or but that additional devices without security-related Restrictions are controllable. The first case relates usually focus on the manual control of a rescue cage, at the certain angle of its bottom to Horizontal must not be exceeded while the second alternative relates to other accessories that does not include passenger transport, such as for example, a water cannon, a platform or a climb.

See further preferred embodiments of the invention before that additional controls for controlling the Movements of additional devices in relation to main control elements for controlling the main movements of the Aerial rescue set are spatially separated and that the Release devices for releasing control elements with switches to deactivate the automatic control are provided by movements, in particular Additional release devices for controls Control of movements of additional devices with Emergency release devices for emergency controls Emergency control are coupled. The latter configuration can be further developed in that additional release devices for controls for controlling Movements of additional devices with emergency release devices are coupled that when the the latter are releasable.

The release devices are preferably more specific Design by covers for the controls formed, the covers in the in the above for the release facilities are coupled together. It is preferably one mechanical coupling provided for covers by articulation of an additional release device acting cover on an emergency release device acting cover or by one the latter trained driver for the additional release device serving cover be formed can.

In a further preferred embodiment, provision can be made be that two or more at the release facilities for Determination of the position of the switches provided can be monitored for their function. This allows the Switching devices with which the release of controls is indicated by the release facilities, be monitored for their functionality.

a schematic overall representation of the device according to the invention.

1 shows the rear part of a fire engine 1 with an aerial rescue set 2 in the form of a Turntable ladder; the vehicle is therefore an aerial ladder vehicle. The ladder for a turntable ladder consists of Usually made up of individual ladder parts that are telescopic are stored, reducing the overall length of the situation can be adjusted. Are on a ladder part itself the so-called rungs parallel to the side members and arranged equidistant in one plane. The rungs themselves consist of slim, rod-shaped full or Hollow profiles.

Next to the lower rear end of the aerial rescue set 2, a main control station 3 is arranged such that a the operator occupying the main control station can see entire lifesaving set and movements can track it directly.

As can be seen from FIG. 2, the main control station has 3 a seat 4 with various controls is provided. It is a main control element 6 for movements of main movements turning f1 and telescoping (Extending and retracting the aerial rescue set) f3, in another main control element 7 for raising and tilting f2 of the aerial rescue set provided. Furthermore is a Validation button 8 for validating the entire system available. There are further key controls 9 available (Fig. 3).

At the front upper end of the aerial rescue set 2 can Additional device may be provided in training 4 is formed by a rescue basket 11. To the detachable hooking a hooking device 12 is provided, which is provided with contacts 13, by means of which validation can be carried out to the effect that the basket is suspended. An alternative accessory can be a water cannon 14 (Fig. 5a). The water cannon 14 is mounted on a suspension device 16, which corresponds to the suspension device 12, or such led him to make an additional, azimuthal movement can execute how this is hatched by the double shown pivoting range 17 is indicated.

More examples of alternative accessories, that are not intended for the transportation of people, such as a platform 18 with, for example, a headlight bridge (Fig. 5b) or a step 19, which is a conductor element is formed (Fig. 5c), can also in the suspension device 16 are stored, the azimuthal movement can be controlled.

6 schematically shows a first embodiment the device according to the invention with emergency controls S21-S24 (also Fig. 7 and 8), an additional control element S31 for an additional device 11, 14 and an emergency release device A2 and an additional release device A3, both of which are realized with covers. The Cover A3 has an adjusting element 21 for adjustment of the control element S31 in a zero position. Both Covers A2, A3 are on a common axis 22 pivoted. If the additional cover A3 is open, as shown in Fig. 6, the control element S31, as indicated by the arrows, can be operated.

The control element S31 is released by a Contact K3a detected that in the illustrated embodiment Contact parts on the cover A3 and on the Cover A2 has.

FIG. 7 shows the same device as in FIG. 6. It is only the emergency release device or cover A2 open. This has, as in FIGS. 6 and 7 is recognizable, a driving element 23, which at Inevitably opening the additional cover A3 opens, even if it was previously closed. Opening the Emergency cover A2 is determined by a contact K2. After opening the emergency cover A2, the emergency control is activated using the S21-S24 controls possible, opening the switch K2 machine-specific Kinematic control system controls switched off and / or optical and acoustic information can be switched on.

The fact that the additional release device or additional cover A3 regardless of the emergency release facility A2 can release the control element S31 via this also manual control functions when not released Emergency operation can be carried out. The fact that at Release by the emergency release device A2 the additional release device A3 with the driving element 23 is always open, even if cover A3 was previously closed in the event of an emergency actuation of the control element S31 ensures.

By designing the device according to FIG. 6 and 7, the operating states "normal state" (closed Release devices), extended operating options with control of the additional equipment via the control elements S31 when the additional release device is released A3 and "emergency operation" by releasing all Release devices A2, A3 recognized.

While the switching elements in the embodiment of FIG. 7 K3a have switch parts on covers A2 and A3, the embodiment of FIG. 8 differs characterized in that a switching part of the switching element there K3b is stationary, so that this switching element K3b the position of the cover A3 opposite the fixed environment detected.

The formation of the mechanical coupling of the release devices A2 and A3 can also - instead of driver 23 - According to FIG. 9 can be realized in that the additional release device A3 on the emergency release device A2 is pivotally mounted about a pivot axis 24. By Unfold the additional release device or additional cover A3 around axis 24 becomes control element S31 Approved. The detection of the release of the control element S31 takes place via a switching element K3b with a stationary and one connected to cover A3 Switching part. Even if the additional release device A3 is closed, the emergency operation is triggered when the Emergency release device A2 by pivoting around the Axis 22 necessarily the additional release device A3 with released what by opening the contact element K3b is detectable.

10 shows an extension of the Device according to the invention with two additional controls S31, S32. Otherwise the configuration corresponds 10 of those of FIGS. 6 and 7. It can also further additional elements with common additional release devices or possibly also individual Additional release devices A3 may be provided.

The arrangement of the switching elements K2 and K3a and K3b require a separate, independent monitoring logic.

The arrangement of the switching element K3a on the emergency release device A2 shown in FIG. 6 detects the state of the covers relative to one another. As a result, the switching elements K2 and K3a are monitored in accordance with the following overview by means of a suitable monitoring unit or logic: Simple monitoring of the binary switching elements K2 and K3a binary switching element and its arrangement Operating mode error arrangement Switching element Normal operation (N) N with subsystem Emergency operation Error K2 or K3a firmly K2 1 1 0 0 at A2 K3a 1 0 1 0 Switching states (0 = open, 1 = closed)

If both switching elements K2 and K3a show an open position, there must necessarily be an error, i.e. one of the switching elements K2, K3a does not work, while by indicating the closed position of both switching elements normal operation, by displaying the opening of the Switching element K2 the release of the additional device or of the subsystem and only by opening the switching element K3a the emergency mode is displayed.

In a corresponding manner, targeted monitoring of the switching element K2 is possible by providing switching elements K2 and K3b in accordance with the configuration in FIG. 9. If the switching element K2 shows an open position, but the switching element K3b shows a closed position, there must be an error in the switching element K2. The other operating states can be found in the table below. Targeted monitoring of the binary switching element K2 binary switching element and its arrangement Operating mode error arrangement Switching element Normal operation (N) N with subsystem Emergency operation Error K2 firmly K2 1 1 0 0 firmly K3b 1 0 0 1 Switching states (0 = open, 1 = closed)

The switching elements K3a and K3b and their arrangement together with the switching element K2 can also be implemented within a device. The following logic then results:

This is a complete surveillance of all of them Switching elements and their combinations possible.

If a rescue kit as an additional device or subsystem has a rescue cage according to FIG. 4, the contacts 13 (corresponding to the switching element BTK of FIG. 11) first carry out a validation in such a way that the rescue cage 11 is suspended and therefore with a passenger transport to calculate. As a result, the inclination of the basket base with respect to the horizontal is generally limited to ± α _limit , for example ± 15 °.

If the additional release device A3 is released during normal operation to expand manual operation, the automatic basket leveling is switched off and manual basket leveling within the limit position range of ± α _{limit is} possible by means of the operating element 31.

If the emergency release device A2 released so that the emergency controls S21-S24 can be operated by the inevitable Opening the additional release device A3 also the control element S31 released. This can also be used in this case the basket leveling can be carried out manually when the Basket suspension validated via switching element 13 or BTK is. In this case, too, the border position monitoring carried out.

If there is no rescue cage available, the Switching element BTK is not validated Ladder operation without a basket, where appropriate a Water cannon 14 according to FIG. 5 can be provided. In in this case there is no passenger transport, and the protection goal of a safe transport of people does not apply through a rescue cage. This means that when released the release device A3 alignment movements throughout constructively kinematically designed area released, such as for a water cannon, and manually executable.

11 shows an overview of an overall system a device according to the invention with associated Control logic. Machine-specific are not shown Self-protection regulations and information circles.

Five releasable functions f1-f5 are shown, of which f1, for example, turning, f2 erecting and tilting and f3 telescoping the aerial rescue set (Aerial ladder) includes, of which over the primary manual operation b1i functions f1-f3 can be carried out are.

Parallel to these primary controls or control units increase additional emergency control units S2j the operational safety of the machine. they seem directly and solve the assigned to them when actuated Motion functions without the logic LG in the The process of movement intervenes. In addition to the three already mentioned main kinematic movements of the boom (f1-f3), in The emergency operating case labeled F1-F3 may determine constructive rung compensation f4 die Kinematics of the aerial rescue set with. In the event of an emergency this is usually an automatically controlled rung compensation function f4 by a manual control unit S24 replaced, with the help of which may be constructive given rung compensation can be controlled and in Function F4 can also be implemented in an emergency can. In addition to validation, emergency operation is required of the overall system (B0) a further actuation B2 for Release of the emergency release device A2. The device hereby recognizes that emergency operation is desired. In addition, access to the controls of the Emergency operation only possible. Will this emergency operation confirmation B2 by releasing the release device A2 completed, this is detected by the switching element K2, so that the emergency operation function for actuation b2j is released are. At the same time, all active Regulations such as rung compensation and basket leveling, deactivated, i.e. no longer of the machine specific Logic LG regulated. As shown above through mechanical coupling of the the two release devices A2, A3 also the latter released and the accessibility of the control element S31 guaranteed for the function fF1 basket leveling, as far as the additional basket is available and by BTK was validated, so that the actuation of the Basket leveling is also carried out manually in an emergency mode can be. But even in this case one separate logic LTK overriding the basket floor leveling avoid by reaching extreme Limit positions of the boom caused manually be canceled.

In an extended operating option without emergency operation the release device can only be operated by actuating B3 A3 are released, so that the additional manual basket leveling fF1 is enabled, what is detected by a switching element. This will specifically targeted the basket leveling regulated by the logic LG switched off and when validating the BTK basket suspension whose logic LTK is switched on in this case too again to prevent extreme inclinations. The automatic, regulated function f5 the basket leveling becomes then replaced by manual basket leveling fF1.

While the embodiment is effective on the five Functions f1-f5, the primary control functions S1i with i = 1 to 3, the emergency operating functions S2j with j = 1 to 4 and an additional control function S31 is restricted the device according to the invention for additional functions expandable (Fig. 10).
