Ram-type test boring system - with leading point comprising concentric disc with diameters decreasing towards end

In a ram-type of test boring system the leading point consists of several concentric discs with diameters which decrease in steps towards the end. The periphery of each disc is designed as an annular cutting edge with a top rake and a clearance angle. Inclined grooves are arranged on each clearance face and the disc assembly can swivel relative to the drill rods. This eliminates the risk of conventional conical points of being deflected by rock and stressing the drill string to breaking point. The new leading point will not become wedged either.

DISC CUTTER

DISC CUTTER ABSTRACT An improved disc type rolling rock cutter, and novel cutterheads employing such cutters. A rock cutter with an improved, simplified structure, with compact bearing, and smooth, rounded blade shape is disclosed. The design incorporates a cutter ring, bearing, and seal into a single cutter ring assembly. The cutter may be assembled and disassembled for rework by a single worker with simple hand tools. Replacement of worn out cutter rings is done quickly and easily by removing the old ring assembly and then sliding a new ring, bearing, and seal assembly on to the cutter shaft. This simplified assembly is achieved by using a comparatively large shaft which is normally in the range of 40-50% of the ring diameter. The shaft design is sufficiently robust to permit a cantilever mount of the cutter. The unique configuration allows 30,000 lbs. or more thrust to be applied to a 5 inch diameter miniature disc. This capacity permits single disc cutter technology to be applied to smaller bits or cutterheads than previously possible. Also, a unique method of shaping and installing hard metal inserts improves cutting efficiency over the life of the cutter, and increases wear life in highly abrasive conditions.

Abstract of the Disclosure A method for assembling rock bit sections in preparation for welding in a manner to assure dimensional integrity. Involved in the method is the use of a clamping fixture that has locator dowels and dowel holes on a base. These locator means are used in combination with a fixed position ring gage, determining the selected diameter of the assembled rock bit, to establish accurate alignment of the sections for clamping and welding. The fixed ring gage and locator means accurately position the sections relative to each other to minimize pre-assembly slippage between the sections.

Rock boring cutter with internal vibrator

A boring device is disclosed having a roller equipped with one or more ring teeth. The roller is caused to vibrate by an internally mounted bob weight. The bearings supporting the roller are of a resilient material to insulate the supporting structure for the roller from the vibration of the roller. In one form of the invention the roller has plural ring teeth of varying diameter and in another form, plural rollers are used with the ring teeth of one roller positioned at an acute angle to those of an adjacent roller.

Bei einer Vorrichtung zum Halten einer Schneidrolle (212) ist eine Fixieranordnung (215) mit Klemmblöcken (303), die mit eine Schneidrollenachse (315) aufnehmenden Achslagerblöcken (312) lösbar verbindbar ist, und mit schräg gestellten Auflageblöcken (318) ausgebildet. In einem Auflageblock (318) ist eine Mobilkopplereinheit (324) einer Lastmessanordnung (327) integriert, die weiterhin über eine von einem Schneidrollenkasten (206) aufgenommenen Stationärkopplereinheit (330) verfügt. Die Mobilkopplereinheit (324) und die Stationärkopplereinheit (330) dienen zum berührungsfreien Übertragen von Energie sowie Austausch von Daten. Dadurch ergibt sich bei einer sehr kompakten Bauform eine verhältnismäßig präzise Lastmessung. In a device for holding a cutting roller (212), a fixing arrangement (215) with clamping blocks (303), which can be detachably connected to axle bearing blocks (312) receiving a cutting roller axle (315), and with inclined support blocks (318) is formed. A mobile coupler unit (324) of a load measuring arrangement (327) is integrated in a support block (318) and also has a stationary coupler unit (330) received by a cutting roller box (206). The mobile coupler unit (324) and the stationary coupler unit (330) are used for the contact-free transmission of energy and the exchange of data. This results in a relatively precise load measurement with a very compact design.

Rotary cutterhead for an earth boring machine

A main frame (24) includes an annular beam (30) by which the cutterhead is mounted onto an earth boring machine for a rotation about an axis of rotation. A plurality of radial spoke beams (28) extend generally vertically at the front of cutterhead and curve rearwardly to intersect with the annular beam (30). Each radial spoke (28) beam is constructed from a pair of spaced apart side plate members (42, 44) which define spaces between them for receiving a plurality of roller cutter mounts (38) therebetween. Roller cutters, including gauge cutters (36), can be installed and removed from their associated cutter mounts from the rear side of the cutterhead. A plurality of generally radially elongate cut-ground-material passageways (46) extend through the cutterhead in the regions between the radial spoke beams. A plurality of concentric, substantially circumferentially continuous face-support-ring members (48) are located forwardly of the cutterhead main frame but rearwardly of the peripheral cutting edges of the cutters in at least the radial region of cutterhead in which the cut-ground-material passageways are located. During rotation of the cutterhead, face-support-ring members (48) support fractured material against the face of the tunnel while the roller cutters (38) cut concentric kerfs with such material.
