Definitions

  • the invention relates to a construction work implement with a base support, a mast which is pivotally mounted on the base support, a first hydraulic cylinder and a second hydraulic cylinder for erecting the mast, which are hinged together in a connecting portion, wherein the first hydraulic cylinder on the base support and the second hydraulic cylinder is hinged to the mast, and a coupling rocker, which is articulated on one side of the mast and on another side to the connecting portion.
  • a generic construction equipment is from the US 4,708,581 known. According to this publication, a generic double-cylinder arrangement is used for erecting and folding a transfer arm, which has a mast-like section. The actual drilling mast is erected by means of a telescopic cylinder.
  • Another construction tool with a mast, on the holder two hydraulic cylinders are arranged one behind the other, is from the JP 05-202686 A known.
  • the JP 2002-285775 A discloses a construction implement, the mast is telescopic and is pivotable about a horizontal pivot axis by means of a hydraulic cylinder.
  • the object of the invention is to develop a generic construction equipment so that a particularly high reliability and cost-effectiveness is achieved.
  • the construction work apparatus according to the invention is characterized in that a spacer is arranged in the region of the connecting portion, through which the connecting portion is releasably supported on the mast.
  • two erecting cylinders coupled in series are provided for erecting the mast, which are connected to one another via a coupling rocker articulated on the mast.
  • the first hydraulic cylinder is articulated in the corner region of a triangle, which is formed by the second hydraulic cylinder, the coupling rocker and a mast section extending between the second hydraulic cylinder and the coupling rocker.
  • the invention has recognized that with such a cylinder arrangement, in particular at the beginning of the erection process, relatively high forces may have to be applied. This may be due to the fact that, at the beginning of the erection process, the hydraulic cylinders, in particular the second hydraulic cylinder, run comparatively flat to the mast longitudinal axis.
  • the force applied by the cylinders force vector thus extends flat to the mast longitudinal axis and, accordingly, small is the force component which acts transversely to the mast longitudinal axis and thus in the raising direction.
  • a basic idea of the invention resides in a spacer with which the connecting section between the second hydraulic cylinder and the coupling rocker can be supported on the mast in the initial phase of the erection process.
  • This spacer allows an additional introduction of force from the connecting portion in the mast and can thus relieve the second hydraulic cylinder, but also the coupling rocker.
  • the spacer can be arranged steeply relative to the longitudinal axis of the mast, preferably at an angle of at least approximately 90 ° to the longitudinal axis of the mast, so that the force vector transmitted via the spacer can point at least approximately in the erecting direction. Since therefore no unnecessary force components must be applied perpendicular to the installation direction, the forces to be applied are relatively small and the hydraulic cylinders are relieved.
  • the hydraulic cylinders can thus be designed with the same mast weight for smaller operating forces, so that the initial cost is reduced.
  • the connecting portion is releasably supported on the mast.
  • the given via the spacer contact between the connecting portion and mast can thus be solved if, especially at a late stage of Aufrichtvorganges, no force on the spacer is required in the mast more.
  • the spacer for a detachable connection on the mast or on the connecting portion that is, the mast or the connecting portion forms a stop for the spacer, which limits further movement of the spacer to the mast or connecting portion, a detachment of the spacer by a Movement from the mast or connecting section, however, allowed.
  • the spacer is held by the mast or connecting portion only to pressure, but not to train.
  • a locking device with which the spacer is releasably held both on pressure and train on the mast or connecting portion.
  • the base carrier may be, for example, a carrier vehicle, or a structure which is releasably attachable to a carrier vehicle.
  • the base support has an at least approximately horizontally extending frame.
  • On the base support can also be provided a winch for moving a drilling carriage along the mast.
  • the mast is pivotally mounted on the base support about a horizontal axis.
  • the mast can be pivotable from an at least approximately horizontal transport position into an at least approximately vertical operating position.
  • the first hydraulic cylinder is hinged at its end facing away from the connecting portion on the base support, and the second hydraulic cylinder articulated at its end facing away from the connecting portion on the mast. It is particularly preferred that the first hydraulic cylinder is articulated on its cylinder housing on the base carrier and / or that the second hydraulic cylinder is articulated on its piston rod on the mast. As a result, the forces to be applied can be further reduced.
  • the spacer is arranged on the mast.
  • the spacer at the connecting portion attached, in particular hinged.
  • the spacer is provided detachably with respect to the mast and moves with the connecting portion as it moves away from the mast during erection of the mast.
  • a further preferred embodiment of the invention is that the spacer is rotatably connected to the coupling rocker.
  • the spacer is rotatably connected to the second hydraulic cylinder, wherein the spacer can then be pivotable relative to the coupling rocker.
  • the spacer may be arranged, for example, on the second hydraulic cylinder. With regard to the design effort, it is particularly preferred that the spacer is arranged on the coupling rocker.
  • the spacer is arranged on the end side of the coupling rocker.
  • the coupling rocker and the spacer suitably together form an L-shape, wherein the angle which is enclosed by the spacer and the coupling rocker, preferably less than 90 °.
  • the spacer is formed integrally with the coupling rocker. According to this embodiment, the spacer and the coupling rocker are fixedly connected to each other and consist of the same material.
  • the spacer has a front face bearing surface for resting on the mast.
  • the spacer may be cylindrical or cuboid.
  • the spacer is formed shorter than the coupling rocker.
  • a corresponding second spacer, on which the spacer according to the invention comes to rest, can be provided on the mast.
  • the two hydraulic cylinders and the coupling rocker are hinged coaxially to each other in the connecting portion.
  • a common pivot axis for the two hydraulic cylinders and the coupling rocker is provided, via which the cylinder and the rocker are connected together.
  • the piston rod of the first hydraulic cylinder is connected to the cylinder housing of the second hydraulic cylinder.
  • a further preferred embodiment is that the spacer extends at least approximately at right angles to a longitudinal axis of the mast when the connecting portion is supported by the spacer on the mast.
  • forces can be introduced into the mast via the spacer in a particularly efficient manner transversely to the longitudinal axis of the mast, that is to say in the direction of erection.
  • the orthogonal arrangement of the spacer is particularly advantageous at the times at which the connecting portion is supported by the spacer on the mast, to which thus the connecting portion rests on the spacer on the mast. At the times when the spacer does not perform supporting tasks and to which the spacer is spaced from the mast, also a different angular position of the spacer may be provided.
  • the design effort can be further reduced by the fact that the mast has a first projection on which the coupling rocker is articulated, and that the mast has a second projection on which the second hydraulic cylinder is articulated.
  • a contact surface is provided for the spacer between the projections.
  • the articulation points for the second hydraulic cylinder and the coupling rocker on the mast preferably have approximately the same distance from the mast longitudinal axis.
  • the contact surface is preferably offset relative to these articulation points and / or the projections to the mast longitudinal axis.
  • a further preferred embodiment of the invention is that the second hydraulic cylinder and the coupling rocker on a first hydraulic cylinder facing Mast Wegseite are hinged to the mast.
