Definitions

  • the application has a screwing device for screwing foundation equipment or the like in the soil as an attachment for attachment to the boom arm of a construction vehicle according to the preamble of claim 1 to the subject, and an excavator with such a screwing.
  • Such screwing devices are known per se. They are available as independent, self-propelled implements with all necessary guides (holding and alignment options) and drives. As such, while they are appropriate and very comfortable, but relatively expensive. They are only profitable, where a large number of foundation equipment is constantly to be used.
  • the described misalignments are compensated in the prior art predominantly via the steering of the construction vehicle or the extension arm, namely by the driver driving the construction vehicle forward or backward depending on the situation or rotating or shortening, extending or pivoting the extension arm.
  • this object also avoids only the problems resulting from movements of the cantilever arm.
  • the font offers no solution. It remains only the readjustment of movements of the construction equipment or movements of the boom or take into account of misalignments.
  • This device is also quite complicated and is above all for long foundation facilities hardly in question, because they would require a height of the cantilever arm, which is hardly available in the conventional construction vehicles.
  • the compensation does not take place here in the cantilever arm and not by its change in length, but in the screwing, more precisely at any point between the pivot point on the boom and the screw head.
  • the error compensation requires no conversion of the construction vehicle or its boom more and no longer needs to be done with the most inadequate means of steering the construction vehicle.
  • the compensation takes place in an already existing additional part of the screw-in device, its suspension. This transformation builds relatively compact, for example, in comparison with the known hydraulic Langenver dichkeit a drilling device. Above all, however, the shift, if it is to be driven and controlled, with the existing in modern construction vehicles anyway, held for the ancillary equipment (hydraulic) drives and their control done. Thus, the control of the shift in the simplest way can be done manually by the operator.
  • the suspension - as for drilling devices - form a universal joint and extend one or both joint axes such that they - and with them the Anlenkstelle and the screw - are mutually displaceable.
  • the task is derived to realize the decoupling of the screwing of disturbing misalignments or incorrect movements of the construction vehicle or the excavator in a simpler, less expensive, less susceptible to failure and maintenance friendly way.
  • the suspension by means of which the screwing - optionally via a common quick coupling - is articulated at the articulation point of the boom, has a designed as a pivot lever formed actuator, which on his schraubkopf alleviaten and on his boom - Side end - in the simplest case - to two parallel to each other, transverse to the longitudinal axis of the screw head extending first axis is pivotable such that a Screwing the foundation device occurring in the soil occurring emigration of the boom-side articulation point from the longitudinal axis of the screw head is compensated.
  • the actuator also has at least one end transverse to the longitudinal axis the screw head and transverse to the first axis extending further axis is designed pivotable.
  • the actuator can be made pivotable at its two ends by two further, mutually parallel, transverse to the longitudinal axis of the screw head and transverse to the first axis extending further axes.
  • the simple solution would be that the provided on the one actuator end one pair of axles or provided on both Stellgiiedenden axes couples are formed as universal joints.
  • This solution which turns off instead of a mobility of the parts against each other on a simple pivot lever construction, has significant advantages over the prior art: it simplifies the compensation of possible directional errors compared to the solution according to DE 10 2008 022 478 without giving up the advantages there.
  • the construction according to the invention is structurally much simpler than that of DE 10 2008 022 478. It works with a simple actuator in the form of a pivoting lever and simple joints, as they are commercially available as standard.
  • the actuator may have a rocker. This ensures a particularly accurate guidance of the screwing device.
  • the pivoting of the actuator can be done by hand. However, it can preferably be provided at least one drive for this purpose.
  • This at least one drive can have a control / regulation by means of which the emigration of the articulation point from the longitudinal axis of the screw head can be detected and compensated.
  • the actuator may have at least one inclination switch or a gyroscopic sensor whose signals can be supplied to the drive by means of the control / regulation.
  • the screwing device is basically also seen as a device that is independent of the construction device, this does not mean that both have a common axis and that this common axis also forms the point of articulation and one of the axes of the actuator.
  • the device according to the invention is basically provided as an attachment for construction vehicles, which are designed for a device change, so it comes in the same way their use as a fixed device attachment, such as on an operated only with this intent excavator into consideration. Then it would be appropriate the ringvo device with the excavator so firmly, ie in the operating state inextricably linked to form a unit.

  • a circular line "B" indicates the line on which the articulation point 7 of the foundation device 2 moves on the extension arm 4 during the lowering of the boom 4 in the progress of the screwing operation, if this movement is not corrected the pivot point 7 in the event that the operator attempts to prevent the migration of the pivot point 7 from the line A by steering movements on the excavator or by changing the length of the boom.

Abstract

L'invention concerne un dispositif de vissage (1) pour visser des appareillages de fondation (2) ou similaire dans le sol (3) sous la forme d'un élément rapporté destiné à être monté sur le bras (4) d'un engin de construction. Le dispositif de vissage comprend une suspension (6) au moyen de laquelle il peut être articulé, éventuellement aussi par l'intermédiaire d'un accouplement rapide usuel, au point d'articulation (7) du bras (4) et une tête de vissage (8) qui est reliée à la suspension (6) et à laquelle l'appareillage de fondation (2) peut être accouplé pour le vissage, ainsi qu'un élément de commande (9) conçu comme un levier pivotant qui peut pivoter à son extrémité du côté tête de vissage (10) et à son extrémité côté bras (11) autour de deux axes (13a, b) s'étendant parallèlement entre eux et transversalement à l'axe longitudinal (12) de la tête de vissage (8) de telle manière que du fait d'une dérive du point d'articulation (7) en dehors de l'axe longitudinal (12) de la tête de vissage (8) survenant lors du vissage de l'appareillage de fondation (2) dans le sol (3) du fait du pivotement du levier pivotant (9) autour des axes (13a, b), le point d'articulation (20) sur la tête de vissage (8) suive son mouvement sur l'axe longitudinal (12). Les axes (13a, b) s'étendent transversalement à la direction longitudinale (14) du bras (4) et peuvent être complétés par au moins un autre axe (15a, b) monté transversalement à ceux-ci pour compenser ainsi une dérive du point d'articulation (7) dans chaque direction.
