Definitions
- the invention relates to a trench wall milling device according to the preamble of claim 1.
- the invention further relates to a suspension sled, especially for such a trench wall milling device, which along a mast is feasible.
- a diaphragm wall milling device is made, for example the utility model DE 87 14 969 U1 known, which on the applicant goes back.
- Such trench wall milling devices are used in civil engineering for the production of diaphragm walls used in the ground. Here cut or break counter-rotating cutting wheels with teeth the floor and transport it to the center where it is sucked off together with surrounding support liquid. In a regeneration plant, liquid and soil are separated, the support fluid is pumped back and stands again at the milling point. The necessary for this Hoses are automatically defined under a Tension of the milling machine penetrating into the ground.
- the feed force of the milling machine is determined by its own weight generated. To see if the milling machine deviates from the desired one Avoid the vertical milling direction, the milling machine is possible to keep them free of lateral forces through the supply hoses. In the known trench wall milling device this by means of a complex tensioning device for the supply hoses reached.
- a generic trench wall milling device is in the Brochure "The Bauer device range” from April 1995 revealed.
- a milling machine is stored on a mast.
- the router is suspended from the mast head with a rope.
- the hydraulic belt systems are used to sink the tiller and the conveyor hose system via a hose drum system, which above the driver's cab as a round drum is arranged with hydraulic drive, tracked.
- the The router hangs on the main rope, which runs over the mast head becomes. After sinking the tiller to a specific one Final depth and the complete unwinding of the hydraulic and delivery hoses the hose deflection slide can be removed from the hose system are led down along the mast.
- Trench wall cutters are a winch for the main rope the router, a winch for the rope to move of the carriage and a drive for winding up the delivery hoses on the drum necessary.
- the invention has for its object to provide a trench wall milling device and a suitable suspension carriage, with which the structure of the device is simplified and at the same time a reliable guidance of a milling cutter is achieved when a milling slot is introduced into a floor.
- the invention allows a vertical guidance of the trench cutter with high directional stability.
- the pulleys on the guided suspension slide together with an articulation of the tether of the router a parallel and even supply of the supply hoses and the tether is ensured.
- the linkage can consist of one or more roles as well as one or there are several ropes for the router.
- a particularly preferred embodiment of the invention exists in that the linkage of the tether is a rope pulley and that the tether to the lower End of the mast and is attached there.
- the other The end of the tether is firmly connected to the milling machine, whereby the tether via a pulley on the suspension sled is led.
- Moving the suspension sled causes according to a pulley principle a shifting of the suspended milling cutter by double Length.
- the same applies to the supply hoses, which over the deflection rollers on the suspension slide from the Milling machine to a regeneration system on the floor or lower End area of the mast are guided.
- a drive for vertical displacement of the suspension carriage is provided.
- the hanging carriage is usually located during the milling process at the top of the mast. Because of its own weight the attached cutter has a corresponding pulling force down on the suspension sled.
- a drive to The sliding carriage must therefore be moved vertically when the cutter is brought down essentially a brake or Apply holding force to a controlled down Ensure routing the router.
- pulling out the The milling machine is a corresponding one from the drive of the suspension carriage Including torque to lift the router of the suspension carriage.
- Suitable engine and transmission combinations can be provided.
- the drive of the Suspension carriage has a drive cable, which on Articulated sled and a roller on the head of the Mastes is led.
- the drive cable for the suspension sled can with a winch at the bottom of the mast, especially connected to an uppercarriage or a carriage his. The winch can be moved through a construction machine Electric, hydraulic or internal combustion engine driven his.
- the milling machine will be brought down particularly reliably achieved according to the invention in that a Longitudinal and transverse guide designed for the suspension slide is.
- On the essentially vertical mast can provide guide rails and / or guide grooves be in which corresponding grooves or strips on Suspension slides are guided.
- Trench wall milling device is achieved in that the Length of the supply and disposal hoses about twice Height of the mast corresponds. Winches or reels for Pick up the supply hoses on the mast or the undercarriage are therefore not necessary.
- the invention Diaphragm wall milling device in this way a diaphragm wall to a depth of about 40 meters. This is sufficient for the majority of all civil engineering designs, only in rare cases, diaphragm walls into even deeper areas have to be brought down.
- a suspension carriage which is characterized in that a Linkage for a tether and a first hose guide roller for the supply hose and a second hose guide roller are provided for the disposal hose.
- suspension carriage according to the invention thus allows a reduction in investment costs Construction machinery and ensures better machine use, which in turn helps to reduce costs.
- a linkage is provided for a drive rope is.
- the deflection pulleys are to avoid tilting moments for the hoses symmetrical on both sides of the suspension slide arranged while a linkage or Deflection roller for the tether and the linkage for the Drive rope along a central axis of the suspension slide are arranged.
- the drawing shows a partial perspective view of a diaphragm wall milling device according to the invention with a suspension carriage according to the invention.
- a vertical mast 30 provided along its front a plate-shaped guide 32 essentially over the entire mast length is attached.
- the guide 32 ends at a mast head 34, which one has multi-grooved roller 36 for a drive cable.
- a suspension slide according to the invention is along the guide 32 10 slidably mounted.
- the hanging sled 10 comprises a base plate 11, one on both sides first hose guide roller 14 and a second hose guide roller 16 are rotatably attached.
- On the two Hose deflection rollers 14, 16 are not shown Hoses led to the supply and disposal of the milling machine.
- a roller holder 20 provided in which for the articulation of a tether for the router a deflection roller 12 and an oblique spacer roller 13 mounted underneath are mounted.
- the tether for the router is on one attached lower end of the mast 30 and along the mast 30 led to the pulley 12, the other end of the Tether is connected to the router.
- the spacer roll 13 provides a sufficient distance from the tether to Mast 30 sure.
- the sled can be lowered by one meter.
- the Milling machine twice the length, i.e. two meters.
- the Milling machine twice the length, i.e. two meters.
- the invention simplifies the construction of a Diaphragm wall milling device with simultaneous improvement the milling guide.
- a suspension slide according to the invention can also use conventional milling devices converted a drilling mast for the production of diaphragm walls become.
