Definitions

  • the invention relates to a movable machine with a machine chassis and work tools and floor support struts arranged thereon, the machine chassis being movable via a cable crane and lowerable to the floor.
  • Movable machines with implements on the machine chassis and floor supports including outrigger supports, for working on paved ground and off-road, are common as wheeled and caterpillar vehicles, on the chassis of which pivotable implements such as drilling equipment, rams, excavators, cranes and grabs are arranged.
  • pivotable implements such as drilling equipment, rams, excavators, cranes and grabs are arranged.
  • felling heads and harvester heads are also known as such tools in the forestry field, the harvester heads being used for the automatic felling, delimbing and cutting of trees.
  • the function of the implements can result in shear and tensile forces that exceed the static friction of the support struts on the ground and tilting moments that are not compensated for by the counter-moment of the machine's own weight, which can cause the machine to tip or slip and thus cause it to slip Damage.
  • the object of the invention is therefore to prevent the machine mentioned at the outset from tipping over or sliding off during use in the field.
  • Another object of the invention is to provide a movable machine that enables simple construction and also offers a cost-effective way of removing material.
  • At least one of the floor support struts is provided with a device for fixing the floor support strut relative to the floor.
  • the at least one floor support strut, on which the weight of the machine rests, is stabilized with the fixation device against excess static friction on the ground and the risk of tipping and slipping is thereby eliminated.
  • Another advantage of the device according to the invention is that due to the fact that the movable machine is fixed on the ground to the suspension element, which establishes the connection with the movable and clampable trolley of the cable crane, less mechanical requirements can be imposed than on the one in WO 02 / 16182 A1 disclosed machine.
  • the device for fixing the base support strut can be formed by an openable and closable gripper.
  • This type of fixation is often very useful, especially on hard ground (e.g. frozen ground), because it is the machine chassis can be stabilized very easily in the field.
  • hard ground e.g. frozen ground
  • there are often floor projections for anchoring the floor for example rocks, but also tree stumps or living trees that can be gripped very well by a gripper.
  • the device for fixing the floor support strut is formed by a drilling device integrated into the ground support strut with a locking drill spiral, which can be screwed into an underground by means of the drilling device. In this way, a releasable fixation of the ground support struts in the rock or stone subsoil can be achieved.
  • the machine chassis can be moved via a suspension element with a carriage that can be moved and clamped on the supporting rope of the cable crane and can be lowered to the floor, wherein the suspension element can be realized by a telescopic rod.
  • the suspension element is a simple cable pull or a cable pull with deflection pulleys, preferably a suspension point of the cable pull being formed by a swivel arm which enables the center of gravity of the machine chassis to be shifted relative to the carriage.
  • a cantilever element is provided on the machine chassis, which can be mechanically coupled via a coupling element to a carriage which can be moved and clamped on the supporting cable of the cable crane, so that the machine chassis is suspended, movable and by means of the cantilever element on the carriage can be lowered to the floor.
  • a special Suspension element and a second carriage for transport can be saved, so that only one carriage for transport and for the process is necessary.
  • a further reduction in the design effort results if a transport receiving basket is suspended from the first carriage, into which the cantilever element can be hung. This eliminates the need for an additional carriage for material transport.
  • three floor support struts are preferably provided which can be pivoted in at least one plane relative to the chassis or frame. These floor support struts are used primarily to achieve the non-rotatability and support of the chassis in the working position and can therefore be operated individually, and in particular they can be bent over their length and are preferably telescopic.

  • FIG. 7 shows a schematic oblique view of a further embodiment of the machine according to the invention with a rope crane
  • FIG. 8 shows a schematic oblique view of a further embodiment of the machine according to the invention with a rope crane
  • FIG. 9 shows a schematic oblique view of a further embodiment of the machine according to the invention with a cable crane.
  • FIG. 1 and FIG. 2 a harvester head is shown as the working device of the machines according to the invention when working after the tree has been gripped by the harvester head before the felling cut.
  • a clampable carriage 2 with a traction cable 3 runs and from the carriage 2 a suspension element, in this exemplary embodiment a telescopic column 4 is suspended, which carries a frame or a machine chassis 5 at its other end, which is about four hydraulically operated support struts 6 supported on the ground.
  • the machine according to the invention can be moved via the telescopic column 4 with the carriage 2 which can be moved and clamped on the supporting cable 1 of the cable crane and onto the floor lowered.
  • the working tool is a harvester head 8 arranged at the end of a crane boom 7.
  • a second carriage 10 runs on the supporting cable 1 of the cable crane with its own traction cable 11 together with a suspended trunk basket 12 for transporting harvested logs 13.
  • the harvester head 8 is a known roller harvester head with two advancing pinch rollers 9, two pairs of knives and a felling chain saw at the end with integrated length and thickness measurement or a push harvester head.
  • the frame 5 is firmly connected to the telescopic column 4, which can only be tilted but not rotated relative to the carriage 2, so that the frame 5 is always the same with respect to the supporting cable 1.
  • a boom element here a crane boom 7, is articulated via a guide tube 16 to a platform 14 of the machine chassis, which, together with a work cabin 15 and drive units, can be pivoted hydraulically around the telescopic column 4 - and thus also with respect to the frame 5.
  • Fig. 2 shows an embodiment in which the telescopic column 4 is pivotally connected to the frame 5 via a transmission 17 and has a pivot bearing 18 which can be clamped relative to the towing vehicle 2.
  • the crane boom 7 cannot be pivoted horizontally relative to the platform 14 and the working cabin.
  • the latter is rotated in the air with the rotary bearing 18 clamped against the telescopic column 4, lowered and fixed to the floor by means of the floor support struts 6, which, in the same way as in the exemplary embodiment according to FIG a device 50 for fixing the floor support struts 6 to the floor are provided in order to enable this fixing.
  • a mechanically stable position is preferably achieved with three floor support struts 6 fixed with respect to the ground, but the number of floor support struts 6 can be chosen as desired within the scope of the invention.
  • the clamping of the pivot bearing 18 is released, so that the unit consisting of telescopic column 4, platform 14, working cabin 15, crane boom 7 and harvester head 8 can then be pivoted horizontally relative to the supporting cable 2 and the frame 5 via the transmission 17.
  • the function of the implement 9 can result in tensile and shear forces which are absorbed by the inventive fixing of the floor support struts relative to the ground. Tipping moments of the machine according to the invention at the respective work location are compensated for by the support struts 6 fixed relative to the ground.
  • the machine according to the invention enables wood to be harvested in winter. During this time, the least damage to the stock occurs and there is the cheapest wood quality.
  • the floor support struts 6 are fixed, e.g. with a gripper as shown in Fig. 3, on the edge trees of the work line in such a way that the weight of the working machine rests on the floor support struts 6 and the same are stabilized accordingly against excess static friction on the ground.
  • the chassis 5 also serves as a carrier for the energy supplier in the machines according to the invention, as a rule an internal combustion engine which has an electric generator, pumps such as compressors or hydraulic motors, and / or mechanical drives or the like depending on feeds their function.
  • the movability of the machines according to the invention is given by their suspension from the suspension cable of a cable crane, the overcoming of ground obstacles takes place in the air and also the transport to and from the machine of materials necessary for working and accumulating during work. For this purpose, at least one (uphill or downhill of the first carriage), move the second carriage over a - preferably own - pull rope and suspended from this (n) carriage transport container.
  • machines with control cabin are shown - however, it is also contemplated to provide machines with radio remote control, so that there is no operator on board the machine when working.
  • the suspension element for the machine chassis on the carriages running on the rope of the cable crane can be a lifting rope.
  • a deflection pulley for a support cable can also be provided on the carriage, which runs from the end of a boom to a winch on the chassis.
  • Fig.3 shows a device for fixing 50 the floor support struts 6 in detail. This is formed by a hydraulically operated, openable and closable gripper 51, which is shown in FIG. 4 in the closed position, in which it encloses a tree trunk.
  • the device for fixing 50 the floor support strut is formed by a drilling device 52 integrated in the floor support strut 6 with a locking drill spiral 53, which can be screwed into an underground by means of the drilling device 52.
  • the machine according to the invention can thus also be used on stony ground, e.g. find use in oil development.
  • the drilling device 52 drives the locking drilling spiral into the ground and thus fixes the associated floor support strut 6 on the floor or in a wall.
