- DE 22 65 155 A1 and DE 22 65 199 A1 show and describe one mobile aerial ladder that rotates on a lower part of the slewing ring, which can be pivoted on all sides with the chassis of the corresponding vehicle is connected.
- U.S. Patent No. 4,834,215 discloses a fire engine that consists of a semi-trailer truck and a semitrailer.
- the front area of the semitrailer is with a horizontal, transverse swivel axis its rear area connected and is above another horizontal, transverse swivel axis in connection with the articulated lorry. If the fire engine is located at an in Incline, the front area with the help of actuating cylinders in a horizontal position compensating for the gradient pivoted.
- Leveling in the direction transverse to the vehicle is carried out with the help of hydraulic supports on both Sides of the vehicle that cover the front area of the trailer if necessary Lift off the floor and align.
- the object of the invention is to create an alignment device of the type mentioned above, which is a perpendicular Align the vertical axis reliably and especially with Using simple means.
- the essence of the invention is a luffing mechanism between two slewing rings to provide.
- the luffing mechanism preferably has one central pivot axis, which is also the diameter corresponds to the slewing rings.
- the luffing mechanism can in particular by actuating cylinders be replaced that the upper slewing ring has at least one Adjusting cylinder connected to the lower slewing ring and lengthways two opposite slopes of the lower slewing ring is movable.
- the extensions intersect the slopes of the lower turntable in the vertical Central axis of the lower slewing ring above it.
- there can be two identical slopes on each side be provided with respect to the vertical central axis.
- the Slopes are preferred as a guide for separate components, which are firmly connected to the lower slewing ring, whereby in the scenery guides scenery stones of the upper slewing ring intervene slidably.
- the advantage of this latter Design variants is that lower bearing forces occur due to a larger lever arm and the force curve can be transferred directly to the base.
- a luffing mechanism is provided between the two slewing rings, it preferably has two peripheral swivel bearings, which is diametrically opposite on the circumference of the two slewing rings Place.
- the luffing gear comprises a luffing drive, which has a Tilt sensor can be controlled around the vertical axis of the adjustable Align the structure automatically.
- the rocker drive has two hydraulic peripheral Actuating cylinder on the circumference of the two slewing rings are arranged in diametrically opposite positions, the pivot axis of the luffing gear in the middle between the two actuating cylinders.
- the base which is the chassis of an ambulance can be on the usually sloping surface positioned.
- the upper and lower slewing rings are located here parallel to each other.
- the vertical axis of the vehicle is inclined according to the slope of the surface.
- the lower rotary drive of the lower turntable preferably via a further level or inclination sensor actuated to the two diametrically opposite Through to the lowest or highest position
- the whole turns Structure, aerial ladder, etc. with. Are the highest and the the lowest position of the two actuating cylinders is set lower rotary drive or its drive pinion non-positively connected to the vehicle frame or underframe, so that the lower slewing ring is blocked.
- the Luffing drive of the luffing gear which over the assigned Inclination sensor for the vertical position of the vertical axis of the adjustable structure is controlled. More specifically the lowest one is a hydraulic one Adjusting cylinder of the luffing gear extended while the other hydraulic actuating cylinders at the highest position is retracted until the upper slewing ring is exactly horizontal is aligned. Accordingly aligned horizontally is then the upper adjustable structure, and it can this through the upper actuator of the upper slewing ring twisted exactly in the horizontal and for example a turntable ladder arranged thereon in a certain turntable and height position are driven.
- the upper and lower rotary drive during the compensation process for Alignment of the vertical axis can be operated simultaneously and in opposite directions such that the structure does not rotate and only takes part in the seesaw movement.
- a particularly simple construction of the alignment device results itself if slewing rings, actuators and / or actuating cylinders are essentially the same.
- the invention uses only two of the same Standard slewing rings allow which of only two of the same Standard actuators or rotary drives must be driven.
- the complicated oblique is advantageously eliminated Training of the intermediate slewing ring mentioned above and its actuator, especially the comparative complicated manufacture of the convex known drive pinions.
- the arrangement consists of simple components and there is also a simple control and position control.
- Another particularly advantageous development of the invention is characterized in that the lower slewing ring by means of a ball slewing ring in the form of a roller bearing is replaced and the latter instead of the lower rotary drive has a locking device through which the ball slewing ring with regard to the base can.
- the luffing gear is first turned until the positioning cylinders are in the fall line.
- the ladder support of the commercial vehicle serves as a counter-holding device for the assembly during the turning process of the luffing gear. If the actuating cylinders are in the fall line, the parking brake is applied. The ladder is then raised. After an upright angle of approx. 5 °, the luffing cylinders start to work and bring the vertical axis into line.
- a level swivel block with an upper swivel head, rocker, roller bearing and parking brake with effect in the direction of the base frame has great advantages in addition to a simple overall structure.
- DE-PS 20 36 559 is a rocker-like yoke linkage a mobile pull-out ladder, especially a fire ladder, known.
- the known yoke linkage requires always one during the rotation on the inclined plane Readjust the ladder or the basket floor to the horizontal Level.
- the alignment device according to FIG DE-A-22 65 165 is not the essence of the invention.
- the fire engine illustrated in Figs. 1 and 2 includes a device (10) for the vertical alignment of the Vertical axis (9) one with a base (11) rotatable and inclinable structure (7) consisting of carriage and Turntable ladder (12).
- the base (11) of the fire engine is a lower one ball-bearing slewing ring (2) assigned, which by a lower rotary drive (4) can be adjusted or turned can.
- the lower rotary drive (4) has a blocking device, to fix the lower slewing ring (2).
- the rotatable and inclinable structure (7) is on the underside an upper turntable (8) assigned by a upper rotary drive (3) can be driven or adjusted can.
- Lower (2) and upper (8) slewing rings and lower (4) and the upper (3) rotary drive are designed essentially the same.
- a luffing gear (1) which is essentially consisting of two disks with swivel bearings connected to them (5) consists.
- two are diametrically opposite Swivel bearing (5) is provided, as illustrated in Fig. 2 is.
- Both swivel bearings (5) have the same central one Swivel axis (13).
- the luffing gear (1) in turn has a luffing drive in Form of two hydraulic peripheral actuating cylinders (6), which on the circumference of the two slewing rings (2, 8) on diametrically opposite Are fixed, the pivot axis (13) of the luffing gear (1) in the middle between the two actuating cylinders (6) lies.
- the rocker drive can be controlled via an inclination sensor, about the vertical axis (9) of the adjustable structure (7) in the to align the vertical position.
- the tilt sensor controls the luffing cylinders with the help of the hydraulics or the hydraulic actuating cylinders (6) and Actuators (3, 4) and puts the implement in Level "zero" as described in detail above.
- the lower actuator (4) becomes non-positive during this process connected to the substructure.
- the implement or the adjustable body (7) with the upper rotary or actuator (3) Rotate endlessly on the horizontal plane without any need to make further adjustments (such as this according to DE-PS 20 36 559 is necessary).
- the lower slewing ring (2) The embodiment variant described above is an economical one Ball slewing ring (14) in the form of a roller bearing and a parking brake in place of the lower rotary drive (4) (15) through which the ball slewing ring is referenced of the base (11) can be determined.
- the conductor support (16) according to FIG. 5 serves as a counter-holding device for the structure (7) during the turning process of the luffing gear (1).
- the aerial ladder (12) is erected. After an upright angle of approx. 5 °, the luffing or positioning cylinders start to work and bring the vertical axis into line. After the required level regulation angle has been reached, the ladder is adjusted in every operating position and is therefore ready for operation in a functionally reliable manner * Tactically, this has great advantages.
- the device (10) for the vertical alignment of the vertical axis (9) according to FIGS. 6 and 7 has instead of the entrance mentioned luffing gear at least one actuating cylinder (17) between the upper slewing ring (8) and the lower slewing ring (2).
- the piston rod (23) of the actuating cylinder (17) on a lower mounting bracket (24) of the upper one Slewing ring in an upper pivot point (25) and the other End of the actuating cylinder (17) via an upper mounting bracket (26) of the lower slewing ring in a lower articulation point (27) articulated.
- Both mounting brackets (24, 26) are essentially the same.
- the backdrop tours are therefore able to absorb tensile and compressive forces.
- the overall arrangement is taken so that in the fully retracted Position of the control cylinder or cylinders (17) upper
- the slewing ring (8) and the lower slewing ring (2) are plane-parallel exactly aligned one above the other with the same perpendicular bisector according to FIG. 6 7, while the actuating cylinder (17) according to FIG. a maximum in its fully extended position Adjustment angle between the upper slewing ring (8) and the lower one Set up slewing ring (2).
- the upper part is in operation for vertical alignment of the vertical axis only in shifted one direction, always against the fall line.
