Abstract

The invention relates to a directional boring appliance comprising a drivable rotating boring rod assembly and a boring appliance which is connected to said rotating boring rod assembly and comprises a boring rod which is provided with a boring tool and is rotatably mounted in a rotationally fixed housing consisting of non-magnetisable steel. Said housing (1) is embodied as a cast steel housing.

Description

Richtbohrgerät directional drilling
Die Erfindung betrifft ein Richtbohrgerät gemäß dem Oberbegriff des Anspruch 1.The invention relates to a directional drilling rig according to the preamble of claim 1.
Ein derartiges Richtbohrgerät ist aus der DE 199 50 040 A 1 bekannt. Das Richtbohrgerät besteht aus einem antreibbaren Drehbohrgestänge und einem an das Drehbohrgestänge angeschlossenen Bohrgerät mit einer in einem drehfestem Gehäuse drehbar gelagerten Bohrstange mit einem Bohrwerkzeug, wie einem Bohrmeißel.Such a directional drilling machine is known from DE 199 50 040 A1. The directional drilling device consists of a drivable rotary drill pipe and a drill connected to the rotary drill pipe with a drill rod rotatably mounted in a rotatable housing with a drilling tool, such as a drill bit.
Die Bohrstange und das Gehäuse bestehen aus nicht magnetisierbarem geschmiedeten Stahl. Die in der Tiefbohrtechnik eingesetzten geschmiedeten Stähle haben eine sehr hohe Festigkeit. Die Bohrstange, das Gehäuse sowie die an dem Gehäuse angeordneten Teile werden aus geschmiedetem NoUmaterial hergestellt, das anschließend zum Endprodukt bearbeitet wird.The boring bar and the housing are made of non-magnetizable forged steel. The forged steels used in deep drilling technology have a very high strength. The boring bar, the housing and the parts arranged on the housing are made of forged NoU material, which is then processed into the end product.
Dieses Herstellungsverfahren ist sehr zeitaufwendig und kostenintensiv.This manufacturing process is very time consuming and costly.
Der Erfindung liegt die Aufgabe zugrunde, ein Richtbohrgerät zur Verfügung zu stellen, bei dem das Gehäuse und die an dem Gehäuse angeordneten Teile mit relativ geringem Aufwand und damit kostengünstig hergestellt werden können, das aber trotzdem die Anforderungen an die Tiefbohrtechnik erfüllt.The invention has for its object to provide a directional drilling rig in which the housing and the parts arranged on the housing can be produced with relatively little effort and thus inexpensively, but which nevertheless meets the requirements for deep drilling technology.
Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst. Weiterbildungen erfolgen gemäß den Merkmalen der Unter anspräche.This object is achieved by the features of patent claim 1. Further training takes place according to the characteristics of the subclaims.
Die Erfindung beruht auf dem Grundgedanken, dass das Gehäuse das aufwendigste aller Teile des Richtbohrgerätes ist und das Gehäuse sowie die an dem Gehäuse angeordneten Teile, wie Deckel, Futterring, Gehäuseabschluss und Steuerleisten nicht die Festigkeitswerte von geschmiedetem Stahl aufweisen müssen. Deshalb werden das Gehäuse und die Einzelteile im G sverfahren hergestellt. Die anschließende Bearbeitung der vorgeformten Gussteile ist wesentlich schneller und kostengünstiger möglich. Durch die Verwendung von Gussteilen werden die Kosten für die Fertigung des Bohrgerätes mehr als halbiert. Dadurch werden die Kosten für die Fertigung des Bohrgerätes deutlich reduziert.The invention is based on the basic idea that the housing is the most complex of all parts of the directional drilling machine and that the housing and the parts arranged on the housing, such as cover, casing ring, housing closure and control strips, do not have to have the strength values of forged steel. For this reason, the housing and the individual parts are manufactured using the gas process. The subsequent processing of the preformed cast parts is possible much faster and more cost-effectively. The use of castings more than halves the cost of manufacturing the drill. This significantly reduces the cost of manufacturing the drill.
Die erfindungsgemäße Fertigung des Gehäuses sowie der am Gehäuse angeordneten Teile, wie Deckel, Futterring, Gehäuseabschluss und Steuerleisten eignen sich für alle auf dem Markt befindlichen Richtbohrgeräte und Spezialgeräte. Es muss darauf geachtet werden, dass die vorgeformten Gussteile lunkerfrei sind. Die auf diese Art und Weise hergestellten Bohrgeräte erfüllen sämtliche Anforderungen, die in der Tiefbohrtechnik gestellt werden.The manufacture of the housing according to the invention and of the parts arranged on the housing, such as cover, casing ring, housing closure and control strips, are suitable for all directional drilling devices and special devices on the market. It must be ensured that the preformed castings are free of voids. The drilling rigs manufactured in this way meet all the requirements placed in deep drilling technology.
Die Erfindung wird nachfolgend anhand einer ein Ausführungsbeispiel darstellenden Zeichnung näh r erläutert.The invention is explained in more detail below with reference to a drawing representing an exemplary embodiment.
Die einzige Figur zeigt ein feststehendes Gehäuse 1 aus Gussstahl, in dem mittig eine Bohrung 2 für eine Bohrstange7 mit einem Bohrmeißel 8 angeordnet ist. Das Gehäuse 1 weist eine Kammer 3 für die Hydraulik und eine Kammer 4 für die Elektronik sowie eine Kammer 5 für den Hydraulikspeicher auf. Außerdem ist in dem Gehäuse 1 noch eine Kammer 6 für die Anschlussplatten angeordnet.The single figure shows a fixed housing 1 made of cast steel, in which a bore 2 for a drill rod 7 with a drill bit 8 is arranged in the center. The housing 1 has a chamber 3 for the hydraulics and a chamber 4 for the electronics and a chamber 5 for the hydraulic accumulator. In addition, a chamber 6 for the connection plates is arranged in the housing 1.
Das Gehäuse 1 besteht aus Gussstahl und ist deshalb deutlich kostengünstiger als ein aus geschmiedetem Stahl gefertigtes Gehäuse. ie Kammern, 3, 4, 5 und 6 sind jeweils mit einem Deckel 10, 11, 12 und 13 verschlossen. n dem, dem Bohrmeißel 8 gegenüberliegenden Ende des Gehäuses 1 ist ein Futterring 14 it dem Gehäuseabschluss 15 angeordnet. Im Bereich der Kammern 3 und 4 des Gehäuses sind Steuerleisten 16 und 17 angeordnet. The housing 1 is made of cast steel and is therefore significantly cheaper than a housing made of forged steel. The chambers 3, 4, 5 and 6 are each closed with a cover 10, 11, 12 and 13. In the end of the housing 1 opposite the drill bit 8, a chuck ring 14 with the housing end 15 is arranged. Control strips 16 and 17 are arranged in the area of the chambers 3 and 4 of the housing.
