Definitions

  • the invention relates to a milling head and a method for processing pile heads according to the preamble of patent claims 1 and 9, respectively.
  • Milling heads for civil engineering are, for example, from [1], "TOP TECHNOLOGY, WHICH WELTS WORLDWIDE", product catalog of erkat - spezialmaschinen - service - gmbh, www.erkat.de, and from [2], DE 100 41 275 A1 known.
  • a device for processing pile heads which has a mounted on a hydraulic support device, such as an excavator, milling head (type: erkat 300-2L). According to [1], the head of a pile can be worked with this device within 30 minutes.
  • Piles of this type to be machined which are typically provided with unstable ground to support a building object, consist of concrete, which can be loaded under pressure, and reinforcing iron, which is loaded on train.
  • the dimensions of the piles are selected according to the construction object and the ground and can vary within a wide range. Typically, piles with lengths of 5 to 50 meters and diameters of 0.4 to 2 meters are used. For the production of the piles, for example, holes are drilled in the ground into which pipes are inserted. The reinforcing iron is inserted into the pipes and the concrete is filled. Earth material, which is located at the lower end of the tube is thereby displaced mostly upwards and found after completion of the pile in the head area, which is why this does not have the required strength. Furthermore, the pile or its head does not normally have the required dimensions. Optionally missing for the construction object required coupling elements. The pile head is therefore mostly processed and rebuilt in the required dimensions and the necessary quality.
  • the prefabricated, usually cylindrical pile head for example, as shown in [1] machined by means of a milling head typically over a length of 0.4 to 1 meter to remove the defective concrete.
  • the concrete must be removed in such a way that the typically arranged coaxially to the longitudinal axis of the pile reinforcing iron is not injured.
  • the milling head shown in [1] the pile core within the reinforcing iron is milled to the edge of the reinforcing iron, depending on the skill of the excavator operator whether it is injured or not.
  • the outer pile casing adjoining the iron reinforcement is removed, which is even more difficult by means of the milling head according to [1].
  • the exposed original reinforcement must therefore meet certain requirements so that the supplementary reinforcement can be mounted.
  • [2] In order to fulfill more complex tasks, [2] requires a complex system with several milling cutters of any shape indicated, which is not suitable for processing pile heads.
  • the present invention is therefore based on the object to provide a method and an improved milling head, by means of which a pile head can be processed faster and more reliable, in particular without damaging the integrated reinforcement.
  • the milling head is used to machine the head of a prefabricated, sunken into the ground pile, which has a cylindrical pile core, a hollow cylindrical pile casing and an interposed, cast-in concrete metal reinforcement substantially.
  • the chiselled milling head is connected by means of a coupling device with a drive shaft which is movable by means of a lifting and drive unit, in particular raised and lowered, and is rotatable for the operation of the milling head.
  • a lifting and drive unit is preferably an excavator or a cable crane, which carries a corresponding drive device.
  • a central milling cutter provided with a plurality of central chisels and a ring milling cutter provided with a plurality of annular chisels are fixedly coupled to one another and aligned coaxially with the longitudinal axis of the drive shaft.
  • the central chisels are arranged in a central annulus and the ring chisel, separated by a central annulus thereof, in an outer annulus, the annuli are at least approximately perpendicular and concentric with the longitudinal axis of the drive shaft.
  • the segments of the pile core and the pile mantle can be removed by a linear lowering of the milling head.
  • Complex movements of the milling head which had to be carried out with a conventional tool by a skilled craftsman, omitted.
  • the processing of the pile head therefore succeeds within a few minutes (earlier according to [1] half an hour).
  • the drill bit is evenly loaded so that more uniform and longer maintenance intervals result.
  • the central annulus, within which the central chisel of the central milling machine are seconded, is preferably shifted 5 cm to 20 cm outwards relative to the outer annulus, within which the ring chisels are arranged, so that when machining a pile head, the central milling machine first linearly into the pile core penetrates and the ring mill is adjusted accordingly.
  • the central milling machine is provided with a central drill aligned coaxially with the longitudinal axis of the drive shaft, which projects beyond the chisel and serves for the more precise guidance of the milling head during the machining of the pile.
  • the central chisel and the optionally provided central drill are arranged on the front side on a shaft, preferably provided with a conveyor spiral.
  • the ring chisel are preferably mounted on an outer mounting ring which is fixed or detachably connected to a mounting cylinder.
  • the shank of the central milling machine and the mounting cylinder of the annular milling machine which run coaxially to the longitudinal axis of the drive shaft and thereby define an at least approximately hollow cylindrical void volume, are connected to the inside of a coupling plate, on the outside of which the coupling device which can be connected to the drive shaft is arranged.
  • the coupling device preferably has a mounting sleeve with a polygonal hollow profile, in which the inserted drive shaft can be locked, for example by means of a bolt.
  • the provided on the milling preferably identical chisel are subjected during operation of a high load and therefore preferably consist of a weldable or form-fitting mount and a chisel element can be inserted therein, which can be routinely replaced.
  • the brackets are secured by positive connections, e.g. Dovetail connections, connected to the associated mounting elements or mounting rings.
  • central drill is front side in the shank of the central milling used, at the front workedem the central chisel are attached.
  • the central drill can therefore easily be replaced.
  • central drill is connected to an inner mounting ring to which the central chisel are attached.
  • the central chisel and the central drill can therefore be replaced with each other.
  • the inner and the outer diameter of the inner mounting ring and the outer mounting ring are preferably precise to the Dimensions of the pile and the position of the reinforcement in the pile adjusted so that maximum removal of concrete is ensured and there is a minimal risk of injury to the reinforcement.
  • the appropriate mounting rings can be placed to adapt the milling head to the pile to be processed.
  • a preferably manually operable coupling element is provided on the coupling plate, in which the shank of the central milling machine can be used. This results in the possibility to remove the entire central milling machine from the milling head and exchange.
  • FIG. 1 shows the underside of a milling head 1 according to the invention, which has a central milling machine 11 serving to machine the pile core 81 and an annular milling machine 12 serving to remove the pile muffle 82.
  • the central milling machine 11 carries at the front a central drill 114 and six central chisels 111, which surround the central drill 114 along an inner circular ring kr1 in a ring-shaped manner.
  • the annular milling machine 12 has a mounting ring 122 on the front, mounted on the four quadrants, six ring chisel 121 are, which act within an outer annulus kr3.
  • a middle circular ring kr2 is kept free, into which none of the central chisel 111 or the ring chisel 121 can engage.
  • the material to be removed is removed in one operation, after which only one provided with the reinforcement 83 concrete sleeve 88 remains, which corresponds to the central annulus kr2.
  • FIG. 2 shows a partial section through the milling head 1 with the cutting elements of the circular milling machine 12 and the distance h3 deeper lying milling and drilling elements 111, 114 of the central milling machine 11.
  • FIG. 3 shows a milling head 1 according to the invention with the in FIG. 2
  • the mounting ring 122 with the ring chisels 121 is connected to the underside of a hollow mounting cylinder 123 (see also FIG. 2 ) whose top is connected to a coupling plate 133.
  • the mounting cylinder 123 is further provided with outlet openings 1231 through which the removed material can escape from the milling head 1.
  • a coupling device 13 is attached (see also FIG. 8 ), which consists of a coupling sleeve 131 and a coupling pin 132 insertable therein.
  • the secured by means of optionally provided reinforcing elements 134 coupling sleeve 131 comprises a hexagonal hollow profile into which the correspondingly designed drive shaft 2 can be inserted and locked by means of the coupling pin 132.
  • the milling head 1 can therefore be moved and rotated by means of the lifting and driving device.
  • the drive shaft 2 connected to a suitably equipped excavator (see [1]) or crane.
  • FIG. 3a Furthermore, one of the central chisel 121, which consists of a holder 1111 and a chisel element 1112, shown enlarged.
  • the chisel element 1112 is held in an interference fit in the holder 1111 and can be knocked out after the occurrence of wear and replaced, if necessary be renewed, which is symbolized by B.
  • the brackets can be welded or preferably by means of positive connections, such as dovetail connections mounted and optionally, for example by means of a bolt, secured. Form-fitting connection techniques are particularly suitable because the milling head is preferably always driven in the same direction. If the bracket is mounted form-fitting, it can be removed with a handle or a hammer blow.
  • the central chisel 121 and the ring chisel 121 are preferably configured identically according to the needs of the user.
  • the mounting cylinder 123 further comprises a window 1232 which allows manual engagement in the milling head 1 to actuate an optional provided on the underside of the coupling plate 133 coupling unit 14, in which the shaft 112 of the central milling machine 11 is inserted.
  • the milling head 1 can therefore either a suitable or a new central milling machine 11, as a replacement for a worn-out central milling machine 11, are used, which is symbolized by C.
  • D symbolizes an option which allows drilling and / or milling elements 111, 114 of the central milling machine 11 to be optionally mounted and dismounted.
  • the options C, D and E which may be isolated or in combination, provide significant advantages for the production, operation and maintenance of the milling head 1. Due to the interchangeability of the drilling and milling tools with a basic structure of the milling head 1 a variety of requirements be fulfilled. By choosing the drilling and milling tools in the desired dimensions, the milling head 1 can be adapted in a few steps to the respective structure and the dimensions of the pile 8 to be machined. By appropriate choice of the outer diameter rd2 of the mounting ring 122 can be adapted to the outside diameter d of the pile 8 (see FIG. 5 ). By appropriate choice of the inner diameter rd1 of the mounting ring 122 can be adjusted to the position of the reinforcement 83 within the pile 8.

  • the chisels can be easily repartitioned or replaced. A return to the workshop is possible because the milling and drilling units can be stored in a small space and kept in reserve.
  • FIG. 4 shows the milling head 1 of FIG. 3 in a three-dimensional representation and without window 1232.
  • the shaft 112 of the central milling machine is therefore firmly mounted or screwed.
