(Cl. Z55-20) 7 Claims.
This invention relates to a horizontal boring machine which is adapted to rotationally project a drilling bit to drill a substantially horizontal pilot hole, and to ream the hole as the projected drill stem is retracted.
It is an object of this invention to provide a horizontal drilling machine and drilling method in which a stationary prime mover is equipped with a Kelly bushing in a rotary member through which a kelly is projected; such kelly being connected to the drill stern on which the bit is installed and which drills the pilot bore; and after which the reamer is installed on the drill stem to ream the pilot bore as the drill stem is retracted.
It is a further object of this invention to provide a horizontal drilling machine of this class which is adapted to supply drilling fluid through the Vdrill stem to lubricate the drilling of the pilot hole bit and the reaming of the reamer which enlarges the pilot hole.
It is a further object of this invention to provide a horizontal drilling machine of this class which has a carriage adapted to be fed forward, or retracted outwardly, by manually operable means permitting an infinitesimal degree of control for the drill stem travel.
It is an object of this invention to provide a horizontal drilling machine of this class which has a stationary engine mounted on the frame thereof; which has a kelly rotationally projected through the driving means; and which has a carriage mounted to be moved along the track and to support the drill stem to which the kelly is attached.
Other and further objects will be apparent when the drawings are considered in connection with the specication in which:
Fig. 1 is an elevation showing the machine in the act of reaming out a pilot bore;
Fig. 2 is a plan view of the machine shown in Fig. 1;
Fig. 3 is an elevation of the drive transmission mechanism as viewed on line 3-3 of Fig. 2;
Fig. 4 is a fragmentary sectional elevation showing the carriage, and including a iiuid supply therefor;
Fig. 5 is an end elevation of the travelling carriage, looking in the direction of the arrows on line 5-5 of Fig. 4;
Fig. 6 is a perspective view of the reamer.
As shown in Fig. 1, a prime mover, as a gasoline engine I, is mounted on the main frame 2, consisting of avpair of longitudinal I-beams joined and spaced apart by suitable transverse framing members. This engine has the conventional transmission 3 and gear shift lever 4 and, through speed reduction gearing, such as a belt or roller chain connection 5, rotates the shaft 6, which in turn, through the belt connection l, rotates the gear 8 which has a non-circular hole, as the square hole 9, axially therethrough. The transmission details are best visualized when Fig. 3 is considered,
A kelly, or square cross-section member 8', passes through the hole 9, and has a sliding drive connection t therewith. The opposite end of the Kelly drive shaft is connected by means of the ange coupling or drive joint II) to a hollow sectional drill stem II the initial section of which constitutes a drive connector rotatably mounted as by well known type of rotary and end thrust bea-rings housed by the pillow blocks or bearings I2 and I3 on the carriage I4 for travel back and forth with the carriage. This carriage I4, as most clearly shown in Figs. 4 and 5, has a frame I5 which has the wheels I6 mounted on the axles Il thereof, the wheels riding on a trackway affording by the co-operating ilanges I8 of the spaced I-beams constituting the main frame 2.
The carriage I4 has the shaft 20 mounted for rotation in the pillow blocks 2| thereof. This shaft has on one end thereof the pinion 22, and the other end is of a non-circular cross-section to receive the socket lever 24. On the shaft 20 inwardly of the socket lever 24, the pinion 22 meshes with, and moves along, the rack 26 which is mounted on the frame 2. The longitudinal spacing of the wheels I6 insures that the carriage will move along in a substantially straight line.
A stuiiing box 30 surrounds the rotatable drill stem section between the bearings I2 and I3, and thus moves back and forth with the carriage lil. This stuiiing box comprises the conventional body l3|, gland 32 and closure 33, the gland being moved by the threading of the closure member upon the body so as to compress the seal 34 against the drill stem surface. A connection for iuid, as the connection 35, is provided, as shown inV Fig. 4 and such connection may preferably be a flexible one to accommodate carriage travel as shown by the hose connection 36 in Fig. l.
' A bit,- not shown, which has uid openings therethrough, is employed to drill a pilot hole througha formation, as the formation beneath the railroad or highway 40. In the drilling of such pilot hole the rotation of the prime mover I rotates the gear 8 thereof which in turn rotates or constitutes the rotatable driver for the drive transfer shait or kelly s through the slip drive joint afforded by the sliding of the kelly within the non-circular hole 9. This rotates the bit to drill the pilot hole and the kelly slides through the driving means as the carriage lll is fed orwardly on the track ilanges i8 and direct the drill under the road bed. This feeding of the carriage is best accomplished in practice by manual force on the handle of the socket lever 2li, although a power operated drive under manual control may be employed.
As the pilot hole is bored, it may be necessary in the event the drill stem length is less the length to be tunneled to add additional sections oi drill stem to the drill stem il and this is done by breaking the drill stem section, as by'tongs, preferably at a joint, as shown in Fig. 4, when the carriage approaches the vicinity of the guide post d2, then retracting the carriage and insert-- ing an additional drill stem section. As the drilling progresses, the drilling fluid, as water, or as a drilling mud, is supplied through the hose or connection 3S to the stuffing box 3e into the ports as the drill stem ii rotates. This fluid passes through the hollow drill stem and outwardly through the holes in the bit to lubricate and soften the formation which the bit is drilling.
When the pilot hole it has been completed underneath the road si) to the side opposite the ditch in which the machine has been set up, the bit is removed. Then a reamer 5c is installed on the drill stem I i on the far side of the road, and 'the prime mover i rotates the drill stem l es the carriage iii under control ci rack and p on manipulation, is retracted or moved backwardly and toward the prime mover i. This drill stem rotation and reverse longitudinal movement of carriage causes kthereamer @il to reain out, or enlarge, the hole d'5. Any drill stein sections which may have been added during forward drilling operation will need to be removed in stages as the roaming operation progresses with the back travel of the carriage through pinion and rack operation.
The reamer 5i! comprises a rim 5i which surrounds and is connected as by welding to the outer ends of radially extending arms 52 which are Welded or otherwise connected centrally to a hollow tube The tube 53 is a co-axial extension of the drill stem ii and is either integral with the stem or a separate part joined to the stein by a pipe coupling. `The arms 52 comprise ile which have blade supports 55 connected thereto and v-f ich have mounted thereon a group of radially spaced blades t. The radial location oi the several supports relative to one another is such that the blades of successive supports are staggered or have rotary paths odset and the several succeeding blades co-operate to out throughout the entire diameter of the reamer ie pipes 51% constitute branch conduits commucating with the hollow tube 53 or drill stem end, and Water, or rluid, flows radially outward there through and is discharged through the. jets or ports 5l into contact with the formation being roamed by the blades 5t. Connected to, or adjacent 'the rim 5 l, are mounted blades 58 which have surfaces extending axially, Whereas the surface of the blades E5 extend in a transverse plane acrossthe drill stem axis.
The diameter of the reamer and of the drill vbit Will depend upon the desired size of the tunnel. 1n some instances the use of a drill bit alone maysuoe without being followed up by a reamer enlargementqrlllihen the stroke ofthe i.
machine is completed a conduit such as a pipe line may be projected under a road without naving had to break up the road surface or detour the iioW of road traic. Before inserting the conduit the rea-med out dirt may be removed by drawing forward a suitable clearout plug on the end o a winch cable. A cable may conveniently be to the end oi the drill stem beyond the reamer prior to the start ci roaming operation so that the cable will be pulled through the tunnel as the reamer is retracted and upon completion of the reaming operation the cable can be readily attached a winch.
lrcadly this invention considers a horizontal boring machine having a stationary engine mounted in a track; such engine being adapted to drive a kelly, or non-circular member, which moves axially through the driving means bushlt also considers a machine of this type h has the lielly connected to a drill stem, the v l stein being mounted to rotate in a carriage which is movable along the track.
