Definitions

  • the invention relates to a carriage arrangement for a construction machine with a device carriage, which can be moved linearly along a substantially vertical guide device, and a carriage insert, which can be detachably connected to the device carriage, with a first connection and a second connection being provided, according to claim 1 .
  • the invention also relates to a method for connecting or disconnecting a slide insert to or from a device slide on a construction machine according to claim 15.
  • a device for attaching working equipment to a lifting carriage of a leader of a construction machine is known.
  • Transversely directed, hydraulically actuated locking bolts are arranged on the device carriage, which can move into corresponding bolt receptacles on the working device in order to connect and fasten a working device.
  • the working device which is a vibrator drive in the described embodiment and can weigh up to several tons, must be aligned exactly with respect to the lifting carriage on the leader. This is time and labor consuming.
  • the EP 1 983 149 B1 shows a carriage arrangement for a construction machine with a device carriage, which can be moved linearly along a substantially vertical guide device, and a carriage insert, which can be detachably connected to the device carriage, with a first connection and a second connection being provided, with the first connection being provided connection, at least one insertion link is provided, which is arranged on the device carriage, with at least one insertion bolt corresponding thereto being arranged opposite on the carriage insert, with the carriage insert being able to be pushed in from above relative to the device carriage to form the first connection, and with the second connection being at least a bolt connection is formed with a locking bolt.
  • a rotary drive is arranged on the carriage insert, which can also have a weight of several tons and a vertical height of several meters.
  • a lifting rope is to be used to hang the carriage insert with the rotary drive, with the carriage insert being lowered from above into the relatively narrow bolt entries. Due to the height of the arrangement, it may be necessary for a worker to climb a ladder in order to observe and control a correct insertion process for forming the upper connection from above. This process is time-consuming and can be problematic from the point of view of occupational safety.
  • the invention is based on the object of specifying a carriage arrangement for a construction machine and a method for connecting and disconnecting such a carriage arrangement, with a reliable connection being able to be produced efficiently and safely.
  • the carriage arrangement according to the invention is characterized in that at least one insertion link is provided to form the first connection, which, in the position of use, is either arranged on the device carriage and open at the bottom or arranged on the carriage insert and open at the top, that corresponding thereto at least one insertion bolt is arranged opposite on the carriage insert or the device carriage, wherein, in the position of use, the carriage insert can be pushed in from below relative to the device carriage to form the first connection, and that the second connection is designed as at least one bolt connection with a locking bolt.
  • a basic idea of the invention can be seen in the connection of the slide insert with a device slide on the construction machine to form a first Insert the slide insert relative to the device slide from below into this connection.
  • This process of pushing the at least one insertion bolt into the insertion slot from below can be easily observed and checked by personnel on the ground, even if the insertion takes place a few meters above the ground. This allows safe working on the ground and the use of climbing aids can be avoided.
  • the relative insertion from below can be achieved in that, when the device carriage is stationary, which has preferably been moved to the lower end of the vertical guide on the construction machine, in particular a leader, the carriage insert is lifted by means of a lifting cable at the upper end of the leader and thus in the device carriage is pushed in from below.
  • the hoist rope can be an auxiliary rope of an auxiliary rope winch on the mast or a main rope, which is guided over a mast head and actuated by means of a winch on the carrier device.
  • the carriage insert may be on the ground or suspended from a hoist line at a fixed vertical position while the equipment carriage is moved down the vertical track of the construction machine.
  • the device slide and slide insert can also be moved towards each other together.
  • the insertion link can be set with any course, so that a targeted insertion movement of the carriage insert into the device carriage for forming the first connection is ensured.
  • a pre-adjustment can be achieved by the first connection.
  • a final positioning and fixing is done by pushing in the transverse locking bolt or bolts.
  • the insertion link is designed as a groove which runs essentially vertically.
  • the insertion link can be arranged on the device carriage and directed with the opening downwards or arranged on the carriage insert and directed with the insertion opening upwards.
  • the groove can also have a horizontal or preferably oblique section, so that the end position is approached in a guided manner.
  • Reliable threading of the insertion bolt into the insertion slot can be achieved in a further development of the invention in that the insertion slot in its Entry area has an insertion bevel.
  • the width of the groove of the insertion guide, which is adapted to the diameter of the insertion bolt, is thus widened in the area of the insertion bevel.
  • a further advantageous embodiment of the invention is that the insertion link has an axial stop.
  • the axial stop is located at the opposite end to the open entry area. Due to the axial stop, the entrance link can not only define the position of the carriage insert on the device carriage in a horizontal direction, but also in the vertical direction upwards. As a result, the carriage insert and the device carriage can assume their desired end position relative to one another overall. In this case, to finally secure the position, only the locking bolt or bolts of the second connection have to be inserted in a transverse direction in order to fix the carriage insert in a positionally accurate and secure manner on the device carriage.
  • the axial stop allows high axial forces, which are directed downwards, to be transmitted from the device carriage to the carriage insert. Such axial compressive forces are to be transmitted in a drilling operation.
  • a single insertion link and a single insertion bolt can be provided on a side or, in particular, a central area of the carriage arrangement.
  • a particularly efficient and reliable fixing of the carriage insert on the device carriage is achieved according to a development of the invention in that two insertion guides are provided, one insertion guide being arranged on one of two opposite longitudinal sides of the device carriage or the carriage insert.
  • the arrangement of the insertion links and the insertion bolts in a respective side area of the carriage insert or device carriage also allows precise observation and thus control of the insertion process and thus the fixing on the device carriage.
  • the at least one insertion bolt can have a cylindrical shape.
  • Targeted guidance of the insertion movement of the carriage insert relative to the device carriage, including the possibility of a guided pivoting movement, is achieved according to one variant of the invention in that the insertion bolt has at least one flattened or planar contact section which is attached to a guide surface the introductory link comes to rest. Torque or tilting moments can be transmitted or absorbed via the at least one flattened surface of the bolt, which is not possible with cylindrical bolts. A desired pivoting or adjusting movement of the carriage insert can thus be achieved during insertion. Overall, the insertion and pivoting movement of the carriage insert can be effected relative to the device carriage in the manner of a mechanical link control.
  • the arrangement of the first and second connection to one another on the carriage arrangement can be provided in any way.
  • the first connection with the insertion link is arranged above the second connection.
  • the connection with the insertion guide is the upper first connection
  • the connection with the transverse connecting bolt represents the lower second connection.
  • the second connection is arranged close to the ground, so that the locking bolts can optionally be pushed in or pulled out by hand by a person on the ground.
  • the first connection secures the position of the slide insert in a horizontal direction and that the second connection secures the position at least in the vertical direction.
  • a single bolt connection is provided approximately in a central area of the carriage arrangement.
  • a bolt passage is formed on the device carriage and the carriage insert, through which the locking bolt protrudes for locking.
  • two bolt passages could also be provided at least on the device carriage or at least on the carriage insert, so that a particularly reliable locking can be achieved.
  • the locking bolt can be actuatable, in particular displaceable, by hand.
  • the locking bolt can be adjustable between a locking position and a release position by means of a power-operated adjusting device.
  • the adjusting device can in particular have a pressure cylinder, in particular a hydraulic cylinder.
  • other linear drives such as a ball screw drive or a rack and pinion drive.
  • the slide insert can be used for any purpose. It is particularly advantageous according to embodiment variants of the invention that the slide insert has a rotary drive, a vibrator drive or a ram unit. In particular, these drive units enable practical use in special civil engineering.
  • the invention also includes a construction machine with a vertical mast, in particular a leader, which is provided with a guide device for a device carriage, the carriage arrangement according to the invention described above being provided.
  • the method according to the invention is characterized in that the slide insert is pushed in relative to the device slide to form a first connection from below and a second connection is formed by locking using a locking bolt.
