Definitions

  • the invention relates to a device for vertically aligning the vertical axis of a structure that can be rotated and tilted with a base frame, for example a rescue device with a turntable ladder, telescopic or articulated mast, with an upper slewing ring adjustable by means of a rotary drive, which is assigned to the adjustable structure.
  • an alignment device of the aforementioned type which has three turntables and a corresponding number of actuators in order to align the adjustable structure horizontally with a base frame positioned on an inclined surface.
  • the middle of the three slewing rings arranged one above the other is inclined in order to establish a maximum inclined position between the two other slewing rings with a relative rotation of the individual parts.
  • the middle slewing ring including the associated drive pinion is comparatively complicated to set up and implies high manufacturing and assembly costs.
  • the object of the invention is to provide an alignment device of the type mentioned at the outset which enables vertical alignment of the vertical axis reliably and in particular with the aid of simple means.
  • the essence of the invention is to provide a luffing mechanism between two slewing rings.
  • the luffing mechanism preferably has a central pivot axis, which also corresponds to the diameter of the slewing rings.
  • the luffing mechanism can in particular be replaced by actuating cylinders in that the upper slewing ring is connected to the lower slewing ring via at least one adjusting cylinder and can be displaced along two opposite slopes of the lower slewing ring.
  • the extensions of the bevels of the lower turntable intersect in the vertical central axis of the lower turntable above the same.
  • two identical bevels can be provided on each side with respect to the vertical central axis.
  • the bevels are preferably link guides of separate components which are fixedly connected to the lower turntable, with sliding blocks of the upper turntable engaging in the link guides.
  • a luffing mechanism is provided between the two slewing rings, this preferably has two peripheral pivot bearings which are located on the circumference of the two slewing rings at a diametrically opposite point.
  • the luffing mechanism comprises a luffing drive which can be controlled via an inclination sensor in order to automatically align the vertical axis of the adjustable structure perpendicularly.
  • the luffing drive has two hydraulic peripheral actuating cylinders which are arranged on the circumference of the two slewing rings at a diametrically opposite location, the pivot axis of the luffing mechanism being in the middle between the two actuating cylinders.
  • the base which can be the chassis of an ambulance, is positioned in advance on the generally sloping surface.
  • the upper and lower slewing rings are plane-parallel to each other.
  • the vertical axis of the vehicle is inclined according to the slope of the ground.
  • the lower rotary drive of the lower turntable is then preferably actuated via a further level or inclination sensor in order to adjust the two diametrically opposite actuating cylinders to the lowest or to the highest position by means of rotary movement.
  • the entire structure, turntable ladder, etc. rotates with it.
  • the lower rotary drive or its drive pinion is non-positively connected to the vehicle frame or base frame, so that the lower turntable is blocked. Then the luffing mechanism of the luffing mechanism is activated, which is controlled via the assigned inclination sensor for the purpose of plumbing the vertical axis of the adjustable structure. Specifically, one of the hydraulic actuating cylinders of the luffing gear located at the lowest point is extended, while the other hydraulic actuating cylinder located at the highest point is retracted until the upper swivel head is aligned exactly horizontally.
  • the upper, adjustable structure is then correspondingly aligned horizontally, and it can be rotated exactly horizontally by the upper actuator of the upper slewing ring and, for example, a turntable ladder arranged thereon can be moved into a certain rotational and vertical position.
  • the upper and lower rotary drives can be operated simultaneously and in opposite directions during the compensating process for aligning the vertical axis in such a way that the structure does not rotate and only takes part in the rocking movement.
  • a particularly simple construction of the alignment device is obtained if the slewing rings, actuators and / or actuating cylinders are essentially of the same design.
  • the invention enables the use of only two identical standard slewing rings, which have to be driven by only two identical standard actuators or rotary drives.
  • the complicated oblique configuration of the intermediate turntable mentioned at the beginning and its actuator, in particular the comparatively complicated manufacture of the convex known drive pinions, are advantageously eliminated.
  • 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 is replaced by a ball slewing ring in the form of a roller bearing and the latter has a locking device instead of the lower rotary drive, by means of which the ball slewing ring can be determined with respect to the base frame.
  • a particularly simple level turning block results.
  • a reduction in the rotational play is advantageous. The power flow no longer takes place via two gears, but only via a rotary drive and an (upper) slewing ring.
  • the luffing gear is first turned until the actuating 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 From about 5 o the luffing cylinders start to work and bring the vertical axis into line. After the required level control angle has been reached, the ladder is adjusted in every operating position and is thus ready for operation in a functionally reliable manner. * (whereby the present invention achieves at least the level regulation angle of 7 ° required according to DIN 14701).
  • the alignment device known from US Pat. No. 4,834,215 also deviates significantly from the essence of the present invention.
  • the known alignment device has lower vertical support cylinders on the bottom, which are required for adjustment.
  • the alignment device according to DE-A-22 65 165 does not correspond to the essence of the invention.
  • the known device namely has a ball joint bearing which can be pivoted on all sides and has a counter ring which can be adjusted via cylinders.
  • the fire engine illustrated in FIGS. 1 and 2 comprises a device (10) for the vertical alignment of the vertical axis (9) of a structure (7) which can be rotated and tilted with a base frame (11) and consists of a carriage and turntable ladder (12).
  • the lower frame (11) of the fire engine is assigned a lower ball-bearing rotating ring (2) which can be adjusted or rotated by a lower rotary drive (4).
  • the lower rotary drive (4) has a blocking device in order to fix the lower turntable (2).
  • An upper swivel head (8) which can be driven or adjusted by an upper rotary drive (3), is assigned to the underside of the rotatable and inclinable structure (7).
  • the lower (2) and upper (8) turntable and lower (4) and upper (3) rotary drive are essentially the same.
  • a luffing mechanism (1) which essentially consists of two disks with swivel bearings (5) connected to them.
  • a luffing mechanism (1) which essentially consists of two disks with swivel bearings (5) connected to them.
  • two diametrically opposite pivot bearings (5) are provided, as is illustrated in FIG. 2. Both pivot bearings (5) have the same central pivot axis (13).
  • the luffing gear (1) in turn has a luffing drive in the form of two hydraulic peripheral actuating cylinders (6) which are attached to the circumference of the two slewing rings (2, 8) at a diametrically opposite location, the pivot axis (13) of the luffing gear (1) in the middle between the two actuating cylinders (6).
  • the rocker drive can be controlled via an inclination sensor in order to align the vertical axis (9) of the adjustable structure (7) in the vertical position.
  • the tilt sensor controls the luffing cylinders or the hydraulic actuating cylinders (6) and the actuators (3, 4) with the aid of the hydraulics and sets the implement to the "zero" level as in detail described above.
  • the lower actuator (4) is non-positively connected to the substructure.
  • the implement or the adjustable structure (7) with the upper rotary or actuator (3) can rotate endlessly on the horizontal plane without having to make any further adjustments (as is necessary, for example, according to DE-PS 20 36 559).
  • the device (10) for the vertical alignment of the vertical axis (9) is shown in another embodiment.
  • the luffing gear (1) is first turned until the actuating cylinders (6) are in the fall line. 5 serves as a counter-holding device for the structure (7) during the turning process of the luffing mechanism (1).
  • the aerial ladder (12) is erected. After an upright angle of approx. 5 o , 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. * (whereby the present invention achieves at least the level regulation angle of 7 ° required according to DIN 14701).
  • the device (10) for the vertical alignment of the vertical axis (9) according to FIGS. 6 and 7 has at least one actuating cylinder (17) between the upper slewing ring (8) and the lower slewing ring (2) instead of the luffing mechanism mentioned at the beginning.
  • the piston rod (23) of the actuating cylinder (17) on a lower fastening bracket (24) of the upper slewing ring in an upper articulation point (25) and the other end of the actuating cylinder (17) via an upper fastening bracket (26) of the lower slewing ring in one lower pivot point (27) articulated.
  • Both mounting brackets (24, 26) are essentially the same.
  • the bevels (18, 19) are in particular in the form of link guides of separate components which are fixedly connected to the lower slewing ring (2).
  • link guides (21) - illustrated schematically in dash-dotted lines in FIGS. 6 and 7 bolts or coulisse stones (22) of the upper turntable (8) engage in a displaceable manner, so that the upper turntable cannot be lifted off.
  • the link guides are therefore able to absorb tensile and compressive forces.
  • the overall arrangement is such that, in the fully retracted position of the actuating cylinder (s) (17), the upper slewing ring (8) and the lower slewing ring (2) are aligned plane-parallel one above the other with the same perpendicular bisector according to FIG. 6, while according to FIG. 7 the adjusting cylinder (17) in its fully extended position sets up a maximum adjustment angle between the upper slewing ring (8) and the lower slewing ring (2).
  • the upper part is only ever moved in one direction during operation for the vertical alignment of the vertical axis, and always against the falling line.
  • the advantage of this embodiment variant is that low bearing forces occur due to the larger lever arm and the force curve can be transferred practically directly to the substructure.
