Definitions
- the invention relates to a bogie with a device for terrain compensation, with one around essentially vertical axis of rotation rotatable first slewing ring with a second slewing ring and with a pivot axis, by means of first and second slewing rings at right angles to Axis of rotation aligned axis of rotation aligned pivot axis are pivotable relative to each other.
- the turntable ladder is in the balance, i.e. the rungs are aligned horizontally, so that it can be committed safely. This is not secured when such a vehicle with an aerial ladder stands in an uneven terrain and the aerial ladder in in a direction that is not the fall line corresponds to the terrain, but to this an angle includes. In this case, the rungs of the The aerial ladder is not horizontal, but inclined to the horizontal.
- swash plates have already been proposed rotatable against each other via crowned teeth are and about a wobble relative to each other a compensation of the vehicle slope or the terrain slope can effect.
- Such a terrain compensation is very expensive due to the crowned toothing.
- EP 0 565 833 A1 shows a bogie with a Device for the vertical alignment of a vertical axis one with a base can be rotated and tilted connected construction, with an upper and a lower slewing ring.
- a pivoting of the two slewing rings over one Rocker over a central swivel axis in the area the diameter of the slewing rings is arranged.
- By moving of the upper slewing ring are those with this connected sliding blocks in opposite to that lower turntable connected link guides an actuating cylinder arranged.
- Both versions are a large height and an extremely limited angle of inclination of the slewing rings together.
- the invention is therefore based on the object of a bogie with a device for terrain compensation create that with a minimized height as possible large relative inclination of the slewing rings.
- the stated object is achieved by a bogie with a device for terrain compensation with the Features of claim 1 solved.
- the second or basic slewing ring can be directly above the Substructure and thus largely in a podium covering of the same be sunk so that its top edge and possibly the lower edge of one on it and the basic mounting plate connected to it can be arranged above the podium since the second slewing ring and, if necessary, the base mounting plate no vertical or inclination movements the podium and the substructure.
- the second slewing ring arranged directly above the substructure is, in particular the second slewing ring in one the podium located in the substructure.
- Training provide that above the second slewing ring and below the first turntable a mounting plate are arranged and in particular that the mounting plates stiffened from tube by reinforcement frame are and that the reinforcement frame of the first mounting plate within the reinforcement frame of a basic mounting plate is arranged, with the pivot axis for the slope compensation itself through parts of the Frame extends.
- the fact that the reinforcement frame of Interlocking mounting plates will be a low one Height reached. This is still supported by that the pivot linkage is only one-sided and an inclination compensation only from the (lowest) Swivel position with 0 ° up to a maximum, preferably in the order of 5 to 10, in particular at 7 °.
- FIG. 1 the inventive device for Terrain compensation shown schematically.
- a podium 3 which consists of a frame structure exists on which walk-on panels 4 rest.
- the slewing ring 6 consists of an outer, undermount ring 8, one opposite this pivotable or rotatable ring 9 and between these only indicated schematically here Bearing elements 11, such as a single or a double Ball bearings etc., with which the rings 8, 9 radially and are guided axially.
- the inner ring 9 is with a Provide internal toothing 12 on which a in the substructure 2 arranged swivel drive 13 with a pinion 14 for Swiveling of the ring 9 attacks.
- the quarter turn actuator 13 can be an electrical or a act hydraulic drive, which is a pivoting of the Inner ring 9 allows in any direction by at least 180 °.
- the base mounting plate 16 is by a stiffened on its frame 18 made of square tube. On the base mounting plate 16 is surrounded by another mounting plate 21 on the frame 18. The Mounting plate 21 is also through a frame 22nd stiffened, the frame 22 largely within of the frame 18.
- the mounting plate 21 is on the frame 22, 18 on one Side, seen here in the front area in the direction of travel, pivotable in the vertical direction relative to the Basic mounting plate articulated, the pivot axis S extends perpendicular to the main axis of rotation A.
- the plates 16, 21 are relative pivotable relative to one another by means of an inclination adjustment 23.
- the tilt adjustment 23 can for example formed by a double-acting hydraulic cylinder his.
- first slewing ring 24 designated slewing ring - because it known turntable of a turntable ladder vehicle corresponds.
- This carries the bogie 26 for one Turntable ladder, consisting of a ladder set and if necessary a carriage that is essentially horizontal Raising axis R can be pivoted in a manner known per se is.
- An inner ring 27 of the slewing ring 24 is fixed to the Mounting plate 21 connected and supports via bearing elements 28 an outer ring 29 with which the bogie 26 is fixed connected is.
- the inner ring 27 is with an internal toothing 31 provided, in turn, a swivel drive 32 engages with a pinion 33.
- the swivel drive 32 is firmly connected to the bogie 26. Electrical and / or hydraulic lines for the drive 32 are via a rotary union 34 from the base 2 to Drive 32 feasible.
- the terrain compensation device now works as follows: the device for Terrain compensation is used when the substructure 2 is not in the balance, but on an inclined Area. In this case, after, if necessary the vehicle that supports the substructure 2 is known Was supported, the ladder set if that Vehicle is uphill to a small compensation area erected. Then the basic mounting plate 16 pivoted relative to the base 2 so that the inclination adjustment device 23 in a deepest Position, ie in a "downhill position" of the total inclination comes into position. As a rule, the shortest path from the starting position to the above described operating position selected.
- the base mounting plate 16 relative to the Substructure 2 is also preferably about the same speed the bogie 26 over the turntable 24 opposite the Mounting plate 21 by the same swivel angle, but in pivoted in the opposite direction. This will achieved that between substructure 2 and alignment of the bogie 26 and thus carried by it Head, at least as a result, no change in swivel angle during the terrain balancing process. Then the inclination of the mounting plate is adjusted 21 and the turntable 24 by means of the inclination adjustment device 23 until the bogie pivot axis A aligned exactly vertically, i.e.
- Tilt adjustment device preferably laterally or to the rear also to an additional negative ladder inclination, i.e. alignment of the ladder at an angle can be used below. For example, this is necessary when working on embankments, such as in river areas will or access to a house from one position secured above it on a mountain slope shall be.
