Definitions

  • the invention relates to an extendable ladder set, in particular fire ladder, from at least two ladder parts, which are each formed of spars and between the spars extending rungs, wherein the uppermost ladder part is formed from at least two conductor sections which are interconnected by an articulated connection, the hinge axis is substantially parallel to the rungs, wherein cover in the fully retracted into the underlying ladder part position of the uppermost conductor part of the first conductor portion and the second conductor portion with the underlying conductor part.
  • the invention also relates to a vehicle, in particular a rescue vehicle, with a ladder set designed as an aerial ladder.
  • the DE9416367U1 discloses an aerial ladder for rescue vehicles with a multi-part ladder set of a number of telescopically extendable ladder parts, each with a sprouts lower chord and serving as a railing upper chord.
  • the uppermost ladder part is divided into two and comprises an inner part which has approximately the same length as the immediately underlying ladder part, and an outer part which is articulated by an articulated connection with a horizontal hinge axis to the inner part.
  • the inner part is extended with the additional outer part.
  • the hinge axis lies outside of the immediately below the uppermost ladder part conductor part, ie the hinge axis does not overlap with the immediately underlying conductor part.
  • the outer part protrudes in the basic position above the cab forward and forms an extension of the ladder set, which can be swung over the hinge axis.
  • a work basket is attached at the end remote from the hinge axis of the outer part, ie at the conductor tip. By pivoting the work basket can be placed on the ground, allowing the direct entry and exit of rescue teams.
  • ladders are also called articulated conductors and the outer part is also referred to as an articulated arm.
  • the hinge point is located outside the ladder set. Due to the protruding from the telescopic portion of the ladder joint part results in an unfavorable overall length.
  • the length of the joint part has a great negative influence on the ladder set geometry (ladder set package length).
  • the ladder set In order to achieve a required overall length with fully extended ladder set, either the vehicle must be extended to accommodate a sufficiently long ladder set, or the number of ladder parts can be increased. Both measures are undesirable, the former due to increased space requirements of the vehicle, the second due to the increase in weight.
  • the ladder set becomes harder to achieve a larger projection or a loss of take-off must be accepted.
  • the DE102005024585A1 discloses an aerial ladder for rescue vehicles with a number of telescopically extendable ladder parts, at the top of which a pivotable about a horizontal hinge axis articulated arm is mounted.
  • the hinge axis is located on fully retracted aerial ladder outside the underlying ladder parts.
  • the articulated arm itself consists of two parts, with one part being telescopically extendable from the other part.
  • the EP2182164A1 discloses a ladder set of a plurality of extendable ladder parts.
  • the uppermost ladder section consists of a first ladder section and a second ladder section (articulated section), which are connected to one another by an articulated connection.
  • the length of the uppermost conductor part is substantially the same size as the lengths of the underlying conductor parts.
  • the articulated connection inside the ladder set ie they covered with the underlying ladder parts.
  • This means that the uppermost conductor part must first be extended so far that the joint or the hinge axis is outside the underlying conductor part. Only then can the second conductor section (joint part) be averse. For a long hinge part, this requires a large minimum projection or ladder length.
  • the hinge part is guided over sliding shoes on the underlying ladder section until the top ladder section reaches the head rollers after the pivot point. Only then is the uppermost ladder section guided on the head rollers.
  • the articulated arm lies on the head roll and is guided by it. Only when the bottom cylinder moves over the roller, this slides on a sliding block to bridge the distance to the piston rod. In order to avoid collisions when retracting the ladder parts, it must be ensured that the articulated part is stretched before the uppermost ladder section can be completely retracted.
  • a similar known ladder set consists of four ladder sections from which the uppermost ladder section can be moved with a separate winch (single pullout) while the other three ladder sections are moved synchronously by a second winch.
  • the pivot point can be like the EP2182164A1 be retracted into the ladder set.
  • both solutions are known in which the hinge point is arranged in the lower flange, as well as solutions in which the hinge point is arranged in the upper flange.
  • the joint cylinders which serve as an actuating device for pivoting off or pivoting the joint part, are each arranged in the other belt.
  • the aim of the invention is to provide a ladder set, in which these disadvantages do not occur and which are characterized by a long range, especially on balconies and in the underfloor area (quay wall and bridges) and with the laying of the work platform on the floor in particular before Cab is possible.
  • the ladder set should allow a short overall vehicle length and be characterized by straightforward kinematic processes and relationships. A large spread between minimum and maximum reach should be possible.
  • the ladder set should also be characterized by a small footprint in the ladder movement, small footprint when placing the work platform on the ground, short set-up time and simple control technology.
  • the invention allows a bending of the second conductor section, also called hinge part, even in a position in which the hinge axis of the articulated connection is not completely moved beyond the underlying ladder part. This increases the flexibility and the range of use of a ladder set.
  • An important advantage of the invention is that the length of the uppermost ladder part and thus the total length of the ladder set does not have to be extended in order to allow a decline even in (partially and / or fully) retracted state.
  • the free space in the head area of the underlying ladder parts (s) is free of continuous rungs and at least so wide that the second conductor section (also called articulated arm) fits with its width through the free space.
  • the clearance is formed between the bars or sides of the ladder part and extends between the uppermost continuous rung and the ladder section top, wherein the free space is open towards the ladder section tip, so that the second ladder section passes through the free space (about the hinge axis). can be disinclined.
  • the free space forming head portion of a ladder part is thus 'forked'.
  • the joint part can thus be moved even when at least partially or completely retracted ladder set.
  • the free space including that in the underlying ladder parts
  • the free space is dimensioned such that even when fully retracted position of all ladder parts, a dislike of the joint part is possible.
  • the uppermost conductor part could then be retracted completely even in the case of a bent second conductor section and only then be stretched again, i. be brought into alignment with the first ladder section.
  • the ladder set or the second conductor section can not be damaged when retracted without having previously stretched the second conductor section completely.
  • the joint can be averse, while the ladder set is in the ladder pad.
  • the hinge axis of the articulated connection is in the retracted state within the ladder set.
  • the ladder rungs can be omitted in each case in the region of a ladder part, which overlaps with the respective overlying ladder part when the ladder set is fully extended, i. within the minimum coverage of ladder parts. This ensures the continuous ascendability of the ladder set.
  • the entire range of motion of the joint part is usable with completely retracted ladder set.
  • concepts are conceivable in the joint part can not use the entire range of motion with completely retracted ladder and thus sprouts in the larger, lower ladder parts can be maintained.
  • it may be provided that the uppermost ladder section may have to be extended a little with the ladder section located immediately below, before the articulated section can be dislodged. The hinge point is still within at least one ladder section.
  • the invention is suitable for sequential, synchronous or combined separation systems and has the same advantages as described above.
  • the hinge axis can be retracted within the other ladder parts.
  • a free space in the coverage area of the ladder parts in at least the width of the joint part so that at conductor strokes, in which the hinge axis is located within at least one of the other ladder parts, the hinge part can be disliked by at least one ladder part.
  • the clearance is created in the coverage area of the ladder parts in at least the width of the joint part, so that the ladder set can be partially or even completely retracted at any joint angles.
  • the extent of the free space in the direction along the spars is greater than the distance between two adjacent rungs of a ladder part.
  • the distance refers here to the regular rung spacing, which is formed in the majority of the rungs of the ladder set. The longer the free space, the less strong the top ladder part has to be be extended to the underlying ladder part to be able to decline the second conductor section.
  • the extent of the free space in the direction along the spars is at least twice as large, preferably at least three times as large as the distance between two adjacent sprouts of a ladder part.
  • the required extension distance of the uppermost conductor part, before a dislike of the joint part is possible, further shortened.
  • the extent of the free space in the direction along the spars is at least a quarter, preferably at least half the length of the second conductor section, whereby the required extension distance is further shortened with respect to the length of the second conductor section.
  • the extent of the free space in the direction along the spars substantially corresponds to the length of the second conductor portion, whereby a bending of the second conductor portion is possible even with fully retracted top conductor part.
  • At least two of the conductor parts located below the uppermost conductor part each have a free space, so that the second conductor section can be tilted through the free spaces around the hinge axis in a position in which the articulation axis overlaps with the at least two conductor parts.
  • the joint part can also be disliked by two ladder parts.
  • the extent of the free space in the direction along the spars in one of the ladder parts is greater than in the other ladder part. This allows a dislike of the second conductor section with retracted underlying ladder parts by a certain angle, which in many cases, however, is already sufficient to park a platform attached to the end of the joint part at the bottom. By this measure, the stability of the ladder set is optimally ensured with a corresponding reduction of the free space in the direction of lower conductor parts.
  • all lying below the top conductor part ladder parts each have a free space, so that the second conductor section in a position in which the underlying Ladder parts are completely retracted and overlaps the hinge axis with the underlying ladder parts, can be tilted by the free spaces around the hinge axis.
  • the second conductor section of the uppermost conductor part can be disliked by all the underlying conductor parts.
  • the spars of the first conductor section extend beyond the hinge axis and overlap at least partially with the second conductor section.
  • the sections of the spars that extend beyond the joint axis preferably include at least one bottom flange or its continuation from the first conductor section.
  • This variant additionally allows a guide of the first conductor section without height offset and thus without vibration excitation when driving over a shoulder or a sliding element, preferably over the full stroke of the first conductor section.
  • This embodiment also allows continuous guidance from the side, from above and from below through the next larger ladder part.
  • top conductor part can continue to be performed with a pair of head rollers on the underlying ladder part.
  • a lift-off and side guides for the top ladder part can be positioned or stored in the head region of lying below the top ladder part ladder, whereby the introduced forces and thus the mechanical stability with minimal coverage (extended position) of the ladder parts compared to a solution without joint equal stay.
  • the second conductor section is narrower here than the first conductor section in order to be retracted in the extended state.
  • slide blocks are also conceivable as guide elements.
  • the sections of the spars (or side walls) that extend beyond the joint axis are preferably at least twice as long as the distance between two adjacent sprouts of a ladder section. That in this embodiment, the spar passes through. This allows a secure grip during the transition.
  • the length of the sections of the spars (or side walls) extending beyond the joint axis is preferably at least a quarter, preferably at least half the length of the second conductor section.
  • the extended spars can already take on considerable support functions on the underlying ladder part.
  • the sections of the spars of the first conductor section which extend beyond the joint axis can have essentially the same length as the second conductor section (joint part).
  • the spars (or side walls) of the uppermost ladder section extend to the end of the underlying ladder section.
  • the side cheeks of the first conductor section can be extended to the length of the second conductor section (or articulated arm), so that the head rollers of the underlying conductor part over the entire stroke of the uppermost conductor part can lead this without height offset. If a synchronous extension is provided, there are no restrictions on the ladder lift of all ladder parts.
  • the uppermost ladder part is guided on or on guide elements which are mounted in the underlying ladder part, wherein in the fully retracted into the underlying ladder part position of the uppermost ladder part beyond the hinge axis extended portions of the spars of the first conductor section on or on the guide elements lie.
  • the kinematics of the ladder set is thereby increased and the stability of the ladder set is maintained.
  • guide elements rest from below and / or from the side and / or from above at the sections of the spars of the first conductor section that are extended beyond the joint axis, thereby ensuring a high degree of safety.
  • the guide elements are arranged in the head region of the underlying conductor part, whereby the first conductor section is reliably supported or guided up to the head region.
  • the guide elements are rotatably mounted rollers, whereby friction, effort and noise are reduced.
  • the spars of the uppermost ladder part comprise a lower chord and a upper chord, wherein the articulation axis of the articulated connection is formed in the lower chord or upper chord of the uppermost ladder section.
  • hinge axis in the area between the upper belt and lower belt.
