Definitions

  • the invention relates to a civil engineering machine with a track-bound undercarriage, which has a chassis with wheels for driving on railway tracks, an upper carriage mounted on the undercarriage so as to be rotatable about a vertical axis of rotation, a leader mounted on the upper carriage with a linear guide along which a work carriage with a construction tool is mounted so as to be movable, and a drive unit for operating the civil engineering machine according to the preamble of claim 1.
  • Civil engineering machines are well known and are used, for example, to create bored piles in the ground, ground anchors or to insert sheet piles into the ground by vibrating or hammering. Civil engineering machines are used in particular to carry out foundation work for buildings or along buildings.
  • the EP 0 102 322 A2 shows a rail-bound low-loading bridge with a cable excavator arranged thereon according to the preamble of claim 1.
  • the invention is based on the object of specifying a civil engineering machine with which construction work along railway tracks can be carried out in a particularly efficient manner.
  • the civil engineering machine according to the invention carries the drive unit in the rail-bound undercarriage.
  • a basic idea of the invention can be seen in the formation of a civil engineering machine in which the upper carriage with the construction equipment is integrated with a rail-bound undercarriage, wherein the drive unit is arranged in the rail-bound undercarriage. Unlike conventional civil engineering machines, the drive unit is therefore not arranged in the upper carriage.
  • a drive unit in the sense of the invention is to be understood in particular as an internal combustion engine or an electric motor which serves to drive actuators on the upper carriage, such as actuating cylinders, motors and the like.
  • the drive unit can have at least one hydraulic pump which is arranged together with the at least one drive motor in the rail-bound undercarriage.
  • the actuators can preferably comprise hydraulic components, in particular hydraulic cylinders and hydraulic rotary drives. These can apply large forces or torques with a relatively low weight.
  • a preferred embodiment of the civil engineering machine according to the invention is that the track-bound undercarriage has a length in a longitudinal direction which is significantly greater, in particular at least twice as long as the length of the superstructure.
  • the undercarriage can be designed independently of the superstructure in terms of its dimensions. Due to a significantly greater length of the undercarriage, there is sufficient installation space in the undercarriage to accommodate the drive unit with the various components.
  • a pivot bearing, with which the superstructure is rotatably mounted on the undercarriage can thus be arranged very low. This promotes a compact arrangement and further improves the tipping stability of the overall arrangement.
  • extendable support feet can be arranged on the undercarriage, which can be extended laterally during construction work in order to increase tipping stability.
  • the rail-bound undercarriage of the civil engineering machine comprises a travel drive for automatic travel on the railway tracks.
  • a drive in particular with an internal combustion engine or an electric motor, can be provided on the undercarriage.
  • the drive can also be provided on the undercarriage.
  • the drive with the drive unit for the civil engineering machine. In this case, only one internal combustion engine or electric motor is required.
  • the drive can generally be controlled via a separate control station on the rail-bound undercarriage.
  • an operating cabin is arranged on the upper carriage, via which both the construction equipment and a drive of the rail-bound undercarriage can be operated. This allows efficient central operation.
  • the leader can basically be adjustably connected to the upper carriage via any desired linkage mechanism.
  • the leader can be placed on the upper carriage in a transport position.
  • it is particularly advantageous that the leader is pivotably connected to the upper carriage via a linkage mechanism, whereby the leader can be pivoted from a substantially vertical operating position into a substantially horizontal transport position, which is located longitudinally in front of the upper carriage.
  • the linkage mechanism can in particular have several horizontal pivot axes, so that the leader can assume a vertical operating position or an operating position with a certain angle of inclination thereto.
  • the leader can be pivoted to the linkage mechanism via at least one vertical pivot joint in the operating position, so that the leader can also pivot sideways relative to a support of the linkage mechanism.
  • the leader can be designed as a telescopic leader, which allows further upward adjustment of the leader in the operating position.
  • the linkage mechanism can also include a telescopic arm so that the working radius can be increased.
  • a preferred development of the invention consists in that the leader is placed in the transport position on a shelf which is formed on the rail-bound undercarriage and/or a rail-bound additional carriage which is coupled to the undercarriage in an articulated manner.
  • the rail-bound undercarriage can be designed with two wheel sets or preferably four wheel sets. With a compact design, the leader can be placed in its entirety on the rail-bound undercarriage for transport, on which the upper carriage is also arranged.
  • the upper carriage is mounted approximately in the middle of the rail-bound undercarriage, so that the leader can be placed in the transport position on a rail-bound additional carriage, which is coupled in front of or behind the rail-bound undercarriage of the civil engineering machine.
  • the leader and/or the construction equipment can be separated from the upper carriage for transport.
  • the leader can also be brought into an approximately horizontal position for transport, in which the leader protrudes beyond the rail-bound undercarriage and is held by the linkage mechanism on the upper carriage.
  • any suitable device can be attached to the civil engineering machine as a construction tool.
  • the construction tool has a vibrator, a drilling drive, a piling device, a sheet pile press or a milling machine on the work carriage.
  • the piling device can in particular comprise an impact or hammer unit.
  • a drilling device can be used with a drilling drive, which is used in particular to create bored piles or foundation piles in the ground, whereby a drill hole created is filled with a preferably hardening mass, in particular concrete.
  • the drilling device can also be used to insert drill or screw anchors for foundation measures.
  • Vertical slots can be created in the ground using a milling machine, which, after being filled with a hardening mass, form diaphragm wall segments or connected diaphragm walls in the ground.
  • Pile-shaped or plank-like foundation elements can be driven into the ground using a vibrator, a ramming device or a sheet pile press.
  • a first civil engineering machine 10 is used in conjunction with the Figures 1 and 2 explained.
  • the civil engineering machine 10 comprises a track-bound undercarriage 20 with a flat supporting frame 22 with a chassis 21, at the ends of which a bogie 24 with four wheel sets 25 with rail wheels 26 is arranged.
  • the undercarriage 20 can have a length of about 12 to 18 meters, preferably about 15 meters.
  • an upper carriage 30 with an operator's cabin 32 is mounted so as to be rotatable about a vertical pivot axis 31.
  • a telescopic arm 42 which is adjustable in length, is mounted on the upper carriage 30 so as to be pivotable about a horizontal pivot axis 43 and can be pivoted about the horizontal pivot axis 43 by means of at least one actuating cylinder 38. Preferably, two actuating cylinders 38 can be provided.
  • the telescopic arm 42 is part of a linkage mechanism 40, wherein a holding device 46 for holding a leader 50 is arranged at the free end of the telescopic arm 42 via a detachable connection unit 45.
  • the holding device 46 can be adjusted by means of an inclination cylinder 47 between the Figures 1 and 2 shown, essentially vertical operating position and an essentially horizontal transport position.
  • a swivel unit 48 is arranged on the holding device 46, with which a vertical adjusting unit 49 with the leader 50 can be rotated by a Fig.1 vertical pivot axis can be pivoted.
  • the leader 50 can be adjusted in the vertical direction or in the longitudinal direction of the leader 50 via the vertical support 52.
  • the drive unit (not shown) for driving the civil engineering machine 10 is essentially arranged in a receiving space 23 on the support frame 22 of the undercarriage 20.
  • the drive unit serves both as a travel drive for the undercarriage 20 for automatic movement, for adjusting the upper carriage 30 and the linkage mechanism 40 and for operating a construction tool 70 on the leader 50.
  • a linear guide 54 is formed on a front side of the vertical support 52 of the leader 50, along which a work carriage 60 with the construction tool 70 is mounted so as to be vertically adjustable.
  • the construction tool 70 is designed to create a bore.
  • a drilling drive 72 is attached to the work carriage 60.
  • the drilling drive 72 rotates a Kelly drill rod 71 suspended from the leader 50 via a cable.
  • a drilling tool 73 is detachably attached to the lower end of the Kelly drill rod 71.
  • the construction equipment 70 with the superstructure 30 is pivoted outwards about the vertical axis of rotation 31, usually by about 30° to 60°, in individual cases up to a maximum of 90°, as shown schematically in Fig.2 is shown.
  • lateral support devices 27 with a laterally pivoting swivel support 28 are arranged on the undercarriage 20.
  • Vertically extendable supports 29 are arranged at the free end of the swivel supports 28. This allows the vertical supports 29 to rest on the ground or on prepared support elements 8.
  • an optionally hydraulically extendable support foot 58 can be arranged at the lower end of the vertical support 52 of the leader 50, with which the leader can be supported directly on the ground.
  • Fig.3 is a schematic representation of a possible working range or adjustment range of the civil engineering machine 10 according to the Figures 1 and 2
  • the hatched working area has an inner radius R1, at which the telescopic arm 42 of the linkage mechanism 40 is retracted.
  • the working area is further limited by the outer radius R2, at which the telescopic arm 42 is extended as far as permissible.
  • a working area along the tracks can be reliably processed at a distance within the outer radius R1. If the leader 50 supports itself on the ground with the support foot 58, the working area is extended up to the maximum outer radius R2.
  • Fig.4 is a first transport position of the civil engineering machine 10 according to the Figures 1 and 2 shown.
  • the first transport position can also be referred to as the relocation position, as it is essentially intended for relocating the device at low speed and over short distances.
  • Fig.5 is another civil engineering machine 10 according to the invention in the transport position according to Fig.4 shown, wherein a vibrator 74 is adjustably mounted on the leader 50 as a construction tool 70.
  • the vibrator 74 has in particular rotary-driven imbalances with which targeted vibrations can be generated, for example for driving sheet piles into a ground.
  • Fig.6 is another civil engineering machine 10 according to the invention in the transport position according to the Figures 4 and 5 , wherein the construction tool 70 comprises a piling device 76.
  • the piling device 76 can be used to exert targeted impact impulses for driving supports or piles into the ground.
  • Fig.7 is another civil engineering machine 10 according to the invention in the transport position according to the Figures 4 to 6 shown, wherein a sheet pile press 78 for pressing sheet piles into the ground is attached to the leader 50 as construction equipment 70.
  • a civil engineering machine 10 according to the invention is shown in a different second transport position, which is particularly suitable for covering longer distances.
  • the civil engineering machine 10 with the track-bound undercarriage 20 has an additional carriage 80, which can be detachably coupled to the undercarriage 20.
  • An upper side of the additional carriage 80 is designed as a storage area 82 for the leader 50.
  • a movement can take place automatically or preferably in a train, for example with a locomotive.
  • the leader 50 is brought into a substantially horizontal position via the linkage mechanism 40 on the upper carriage 30 and is placed on the support 82 of the additional carriage 80 immediately or preferably after pivoting by 90° to the side.
  • the pivoting by 90° preferably takes place with a vertical stop.
  • the connection unit 45 between the telescopic arm 42 and the holding device 46 of the linkage mechanism 40 can then be released.
  • the telescopic arm 42 can now be retracted again.
  • the laid-down leader 50 on the additional carriage 80 can be moved sideways and/or in the direction of the track in order to bring the center of gravity of the unit consisting of leader 50 and work carriage 60 as close as possible to the middle of the additional carriage 80.
  • the mast head 56 can be folded down in order to avoid it projecting sideways beyond the width of the additional carriage 80.
  • cable connections 66 can remain between the telescopic arm 42 on the upper carriage 30 and the leader 50 laid down on the additional carriage 80.
  • the cable connections can be power and/or data cables. This means that when another construction site is reached, the leader 50 can be reconnected to the upper carriage almost automatically by extending the telescopic arm 42 and closing the connection unit 45, without the cable connections 66 having to be re-established before work begins.
