Definitions

  • the invention relates to a plant for producing a concrete molding, in particular a concrete pipe, manhole bottom part or the like., Which has at least one compaction tool for distributing and / or compacting concrete in a mold shell and a drive device with at least one drive shaft to the compression tool in the axial direction to move the drive shaft and in the direction of rotation of the drive shaft.
  • the compaction tool and the drive shaft are provided with mutually associated locking means which allow a releasable connection of the compaction tool with the drive shaft.
  • the invention relates to a method for producing a concrete molding, e.g. a concrete pipe body, for example by means of such a plant.
  • Such a change of the compaction tool is usually associated with a workload of about one hour. Since the compaction tools can have a weight of up to 1.5 t, depending on the size, there is also a certain risk of injury and accident for workers who need to loosen or tighten the gland beneath the compaction tool for connection to the drive shaft.
  • Object of the present invention is in contrast to provide a system and a method of the type mentioned above, which allows a rapid and less risky change of the compaction tool.
  • the compacting tool and the drive shaft according to the invention are positively connected, at least in the axial direction of the drive shaft, not by a screw connection. This is preferably done by at least one locking means being movable in a plane which is at least approximately perpendicular to the longitudinal axis of the drive shaft.
  • the invention is based on the idea that a positive connection between the drive shaft and the compaction tool can not only be made and released very quickly, but also has advantages in terms of operability. So it is neither necessary below the To work compacting tool, there is still the risk of incorrect assembly as may occur, for example. When using incorrect screws.
  • the detachable connection of the compaction tool to the drive shaft essentially takes place automatically or mechanically, without requiring manual operation for fastening the compaction tool to the drive shaft or releasing the compaction tool from the drive shaft.
  • the locking means are designed as a latching connection
  • a change of the compaction tool can be carried out particularly quickly and easily. This can take place, for example, within only about two to three minutes.
  • the latching or snap connection can be designed such that the drive shaft is inserted into the compression tool and locked there automatically or vice versa is locked by a movement of the compression tool relative to the drive shaft.
  • the release of the compaction tool from the drive shaft can, for example, be effected in that a corresponding opening element is actuated on the compaction tool or the drive shaft or is moved relative thereto, that the latching or snap connection dissolves.
  • the locking means comprise according to a preferred embodiment of the invention, at least one particular spring-loaded clamping clamp on the compression tool or the drive shaft and a latching recess on the drive shaft or the compression tool.
  • the use of two spring-loaded clamping brackets in the compaction tool, which can engage in corresponding grooves in the drive shaft, has proven to be a particularly reliable connection between the drive shaft and the compaction tool.
  • the clamping chamber there are several ways to open the clamping chamber: either in a so-called active variant, the clamp by movement of the drive shaft in the direction of rotation, axially and / or radially actuated or the drive shaft is in a so-called passive variant only in the direction of rotation, axially and / or radially positioned or aligned.
  • the clip is then opened and / or closed by an external element.
  • connection between the drive shaft and the compaction tool may be configured as a bayonet connection.
  • the drive shaft is firstly moved in its longitudinal direction relative to the compaction tool and then rotated relative to it for locking.
  • the locking means are designed as a toggle lever or a sliding block closure.
  • Such compaction tools usually have at least one smoothing piston and pressing or distributing rollers arranged in at least one plane.
  • at least two levels of pressing or distributing rollers are provided, wherein the upper operating plane of the pressing or distributing rollers may be closer to the longitudinal axis of the compacting tool or the drive shaft to effect a step-wise greater compaction of the concrete when the compacting tool is in the mold jacket is moved upwards.
  • the smoothing piston and at least the press or distributor rollers arranged in one plane can be driven in different directions of rotation.
  • the drive shaft is preferably surrounded by a hollow shaft, which can drive the press or distributor rollers.
  • the connection between the compaction tool and the drive shafts preferably takes place simultaneously.
  • the inner drive shaft can be positively connected in the axial direction with the compression tool, while the outer hollow shaft and the inner drive shaft are both positively connected in the direction of rotation with the compression tool.
  • the drive shaft is designed, at least in sections, as a polygonal shaft. It is particularly preferred if the drive shaft is designed as a square shaft. Alternatively, it is also possible to provide the shaft with a flange which is provided with teeth and / or with holes and corresponding bolts for torque transmission.
  • At least one sensor is provided.
  • a switching cam whose position can be detected by a proximity sensor.
  • a compacting tool is first introduced into a stand for the production of a concrete pipe, having a drive device with a drive shaft for moving the compaction tool in the axial direction and in the direction of rotation of the drive shaft. Subsequently, the compaction tool and the drive shaft are connected to each other by a relative movement of these two components. This is preferably done so that a non-rotatable and solid in the axial direction of the drive shaft connection as possible automatically, that is produced without further assembly work.
  • at least one locking means can be moved in a plane perpendicular to the longitudinal axis of the drive shaft in order to positively connect the compaction tool and the drive shaft at least in the axial direction of the drive shaft.
  • a mold shell can be introduced into the stand and filled with concrete, which is then compressed by the compaction tool in the mold shell. Finally, the concrete pipe can be demolded from the mold shell.
  • connection of the compaction tool with the drive shaft for example, via a snap or snap connection
  • the compression tool and the drive shaft perform a relative movement to each other in the axial direction of the drive shaft to connect these two components together.
  • the connection can also take place via a relative rotational movement of the compaction tool relative to the drive shaft, for example when these two components are to be connected to one another via a bayonet catch or the like.
  • Fig. 1 shown plant for the production of a concrete pipe has an in Fig. 3 closer compression tool 1 and a drive shaft 2, which is detachably connected to the compaction tool 1.
  • the compaction tool 1 is arranged in a mold jacket 3, from which the drive shaft 2 projects upwards.
