Definitions

  • the present invention relates to a system and a method for producing a precision-fitted attachment blade and a corresponding bucket according to the preambles of claims 1 and 7.
  • the ground floor of the bottom sole in particular in pipeline construction, is in the foreground in the manifold tasks of excavating soils. If you want to use excavator buckets, for example, also for cutting or for leveling subsoil areas, that the bucket should have a flat grave edge. Here you consciously take the uneconomic
  • the object of the present invention is to overcome these disadvantages.
  • the cost of transport to the site should be significantly reduced, on site at the construction site intent knives to be quickly produced for certain excavator buckets and attachment blades and dredger blades in case of maintenance quickly be regenerated.
  • the system includes a Grabgefä ß and a G rabgefäß releasable cutting element, characterized as a us by at least one template for attachment of the tooth attachments on the cutting element and at least one Scha blone for d he attachment of the tooth holder on G rabgefäß.
  • the template for attaching the tooth attachments no bucket and the Scha blone for d he attachment of the tooth holder no attachment blade has to do with teachings that are used only for the manufacture, but not for the work itself.
  • an already existing bucket or an already existing attachment knife may also be used as gauges.
  • a cutting attachment is provided with tooth attachments adaptable to the teeth holders of an excavator bucket.
  • a single cutting attachment can be adapted to different excavator buckets and in particular to positions of the tooth brake changed by the operation.
  • there is no damage in the sense of the present invention since it is not possible to create a uniform system of standardized dimensions, but again only an im provement of special bucket dimensions.
  • the system is used for producing a passgena uen header blade and corresponding single bucket with each petba rer Bema tion.
  • "Repeatable” in this context means that a number of buckets or offset knives can be made, each having the same dimensions, which may take any length of time between the production of the bucket or the attachment blade, since the respective templates are used only for the production of these elements and otherwise for nothing else, a lso in particular not to work.
  • the attachment is a non-releasable fixation, preferably a Sch pasverbind ung.
  • the system comprises a cutting element without attached tooth attachments and / or a grave vessel without attached tooth holder and additionally tooth attachments and / or tooth holder. This can be used to make new attachment blades or excavator buckets.
  • the system may also include existing bucket with attached tooth holders and / or attachment blade attached thereto tooth attachments. In this way, the positions of the tooth holders or tooth attachments can then be corrected for maintenance or such tooth holders and tooth attachments can be exchanged.
  • the tooth holder and the tooth attachments are those of standard production.
  • the companies Cargo, MTG, Caterpillar, Bofors, Lehnhoff or ESCO supply appropriate parts.
  • the template for attaching the tooth attachments has a number of tooth holders corresponding to the number of tooth attachments to be fixed, which are arranged at a fixed distance from one another, the tooth holders preferably being fastened on a common first base and / or that the template for the attachment of the tooth holder has a number of tooth attachments corresponding to the number of tooth holders to be fixed, which are arranged at a fixed distance from each other, wherein the tooth attachments are preferably mounted on a common second base.
  • the fixed distance is a constant.
  • the distance is advantageously rasterized, ie that it is selected as a function of the width of the grave vessel. For example, for widths of 500 mm and 600 mm grave vessels, four equally spaced toothpicks are used, corresponding to a pitch of 166.67 mm and 200 mm respectively, and for a width of 800 mm, five tooth mounts are used. which corresponds to a distance of 160 mm. Thus, strictly speaking, not the distance rastered, but the number of teeth based on the vessel width. For larger widths of grave vessels correspondingly more tooth holder and tooth attachments are used.
  • the outer tooth holder of the bucket be arranged so that a free cut is formed and the grave vessel itself does not cut when digging into the digging property.
  • the templates are made so that the bottom of the bucket and the bottom of the attachment blade form a plane.
  • the template for attachment of the tooth holder has a stop edge for the grave vessel and / or that has the template for attaching the tooth attachments a stop edge for the attachment blade. Then the distance between front attachment and bucket can be set very accurately.
  • the templates for bucket and front attachment blade are made so that the cutting element of the attachment blade rests directly on the grave vessel in the arrangement of the attachment blade on the bucket. Due to the high accuracy of fit achieved with the stencil manufacturing no major gap must be left, so that no compensating plates are required.
  • the template for the attachment of the tooth attachments and the template for the attachment of the tooth holder are present as a unitary one-piece template. Then only a single part is present, so that the transport cost to the site is reduced.
  • the templates by certain markings, for example in the form of different colors or characters indicate that the user is identifiable for their intended purpose, so that no confusion can occur.
  • Self-contained protection is claimed for the template according to the invention for the production of an attachment blade with a cutting element and at least two tooth attachments attached thereto, wherein the template has the features of the system according to the invention related to the characteristics of the template for producing a header blade.
  • Self-contained protection is further claimed for the inventive template for producing a bucket with at least two attached tooth holders, the template has the related to the characteristics of the template for the manufacture of a bucket spoiler features of the system according to the invention.
  • At least one of the templates according to the invention is used to produce a repeatable dimensioning element, the element being the attachment blade or the bucket.
  • Self-contained protection is further claimed for the method according to the invention for producing a precisely fitting attachment blade and a corresponding bucket, wherein the attachment blade has a cutting element and at least two attached tooth attachments and wherein the bucket has a grave vessel and at least two corresponding to the tooth attachments of the attachment blade tooth holder, the is characterized in that for the attachment of at least one tooth attachment on the cutting element a template is used and for the attachment of at least one tooth holder on the grave vessel a template is used.
  • the attachment blade and the bucket have a repeatable dimensioning.
  • only one bucket with at least one tooth holder or an attachment blade can be provided with at least one tooth attachment, in which case the respective template is used. Even then, a high recurrent precision in the manufactured buckets or attachment blades is achieved.

Abstract

L'invention concerne un système (1) et un procédé pour produire une lame d'attaque sur mesure et un godet d'excavatrice correspondant, ainsi que des gabarits (3, 9) pour produire une lame d'attaque sur mesure et un godet d'excavatrice correspondant. Cette invention permet de réduire significativement la complexité du transport jusqu'au site de construction. Par ailleurs, directement sur le site de construction, il est possible de produire rapidement des lames d'attaque pour des godets d'excavatrice spécifiques et également d'équiper des godets d'excavatrice au moyen de porte-dents (11, 11', 11"). En outre, les lames d'attaque et godets d'excavatrice existants peuvent rapidement être remis en état lors des maintenances.
