Definitions
- the invention relates to drill rigs of the caterpillar type with a boom which in one end is mounted for pivotal motion about a substantially horizontal axis, and with a feed mast mounted for longitudinal adjustment in a guide pivoted on the free end of the boom, and with hydraulic operation for effecting the positioning movements.
- the boom can either be rotated only in a given vertical plane in relation to the chassis of the vehicle, or it is pivoted on a turntable which itself is mounted for rotation about a substantially vertical axis on the chassis approximately midway between the track frames.
- the invention seeks to overcome the above drawback and contemplates that the turntable be carried by a shaft centrally located in the vehicle with direct rack and pinion operation from a common connecting piston rod between two hydraulic cylinders fixed to the chassis and having sufficient stroke length for rotating the platform 360.
- the said rack .and pinion operation can be obtained with an adequate tooth module for properly takingvup the forces involved even when the feed mast is working' laterally in relation to the vertical longitudinal plane of rotation of the boom and at the same time with a sufficient stroke for 360 rotation by means of a favorable space-saving location of the cylinders in the transverse direction of the vehicle, while at the same time keeping the overall width of the vehicle sufficiently small to permit transportation of the drill rig on a standard truck body.
- the boom can be rotated 360 in the horizontal plane and this axis can be located approximately midway of the length of the track frames in order to operate under conditions as symmetrical conditions as possible and also to make the chassis as compact as possible, with a resulting possibility of positioning the mast at a short distance from the turntable axis in front of or behind the chassis and to obtain the most favorable center of gravity positions.
- an especially favorable feature of the invention in this respect is that the axis for relative pivoting of the track structures is concentric to the said cylinders and these form part of the connection between the chassis and the track frames.
- the maximum height difference between them i.e. the height difference at maximum oscillation angle is reduced, which makes it possible to simplify the construction by having one of the track frames rigidly fixed to the adjoining cylinder and having the other track frame mounted for pivotal motion about the other cylindrical with the possibility of fixation by means of a hydraulic damping cylinder device with an adjustably throttled by-pass.
- the boom is provided with an intermediate pivotal joint permitting it to adopt a downward angle which can be adjusted by means of a hydraulic cylinder.
- FIG. 1 shows a drill rig viewed from the left side
- FIG. 2 is a top view of the drill rig chassis with the mast in the vertical position and in section along the line 11-" in FIG. 1,
- FIG. 3 is a top view of the chassis in section along the line IIIIII in FIG. 4,
- FIG. 4 is a front view of the chassis and turntable in section along the line IVIV in FIG. 3,
- FIG. is a view in longitudinal section of the hydraulic damping cylinder for one of the track structures
- FIG. 6 is a rear view of the boom head and the mast guide
- FIG. 7 is a right-hand view of the same, and FIG. 8 shows the same as viewed from below and in section along the line VIII-VIII in FIG. 6.
- the track structures 1 and 2 of the drill rig are as usual fitted with caterpillar tracks 3 consisting of chains carrying track shoes and running over a driving wheel 4 at the rear end, a rotatable wheel 5 at the front end and guide rollers, all mounted on a fixed frame 6 in the respective track structure.
- the guide rollers along the bottom side are not visible in the drawings, but in FIG. 1 a single roller 7 for the upper run of the track can be seen.
- the driving wheels 4 are operated from separate drive units 8, which are mounted on the respective track frames 6, and each of which may consist of a compressed air motor 9 with a valve lever and reduction gear and capable of being engaged and disengaged by means of a lever 10.
- each track structure may be fitted with" a track-tensioning-spring 11 and the tensioning may be adjustable by means of a hydraulic'cylinder 12.
- the track frames 6 are interconnected by a link rod 13 which has a certain slack permitting relative vertical movement and which is adapted, if desired, for connection, at point 14, of a towing truck or of a portable compressor which can be pulled by the drill rig and feed its compressed air system.
- the actual vehicle chassis 15 of the drill rig consists mainly of a reductiongear box 16 which is centrally located in the vehicle and which is extended to both sides by a pair of aligned hydraulic cylinders 17 and 18 extending through their respective track structures 1 and 2 approximately to the outer edge thereof.
- the cylinder 17 is rigidly attached to the frame 6 in the right-hand track structure 2, whereas the cylinder 18 is supported for pivotal motion, but not for longitudinal displacement in a bearing 19, attached to the left-hand side track frame 6.
- the latter is integralwith a hollow shaft 24 which extends vertically through and is journalled in the box 16 and carries a turntable 25 of the drill rig.
- the cylinders 17 and 18 with pistons and rack and pinion transmission are arranged for efiecting rotation of the turntable 25 through an angle of 180 to either side from the central position shown.
- Hydraulic liquid is supplied to the outer ends of the cylinders 17 and 18 and to the remaining hydraulic cylinders of the drill rig from a source of hydraulic pressure mounted on the turntable 25 and consisting of an oil tank 27 and a pump unit 28 driven by compressed air.
- conduits 26 for hollow shaft 24 are not shown on the drawings as this would make the drawings difficult to understand and unnecessarily complicated and, besides, these systems are conventional, except that conduits 26 for hollow shaft 24.
- a control panel 32 carried by an arm 33 which is mounted on the turntable 25 and can be positioned at different angles in a horizontal plane.
- this structure will adjust itself in relation to the remaining part of the drill rig by following the terrain.
- the weight of the vehicle is to be transmitted'to the feed mast 34, and a rigid connection between the frame 6 of the track structure 1 and the chassis 15 has to be established.
- a hydraulic bracing and damping piston-cylinder unit 35 as shown in detail in FIG. 5.
- the piston 36 works in a chamber through which the piston rod 37 extends with a slideable fit at the ends, and a by-pass conduct 38 extends from one end of the chamber to the other and is fitted with an adjustable throttling valve 39.
- valve 39 By adjusting the valve 39 it is thereby possible to achieve both an adjustable damping of the oscillating movement of the track frame 1 in the terrain and also a locking of the piston when a rigid connectionis required.
- a problem in this connection is, however, that it is difficult to obtain a perfect sealing of the end walls of the cylinder chamber against leakage, which may cause sagging of the track structure in operation. Sealing gaskets as such have proved inadequate, and therefore, in addition to gaskets, closed oil chambers 42, 43 are provided in the end walls 40, 41, which has proved to afford an adequate seal.
- Numeral 44 designates the drill rig boom, which is rotatably mounted on horizontal pivots 45 on the turntable 25 and can be adjusted in relation to the latter by means of a hydraulic cylinder 46.
- the boom 44 is composed of two sections 47, 48 linked together by a pivotal joint the axis 49 of which is parallel to that of thepivots 45, and interconnected by ahydraulic cylinder 50 so that they can be adjusted for adapting different downwardly facing angles in relation to each other.
- the boom is symmetrical with respect to a vertical plane passing through the pivotal axis of the turntable and the boom carries at its outer end a boom head 51 which can be rotated in the swinging plane of the boom on a pivot 52 on the boom section 48 by means of a hydraulic cylinder 53 connected to the boom section 47.
- the boom head 51 is fitted with a rotational bearing for a supporting pin 55 with axis in the vertical swinging plane of the boom.
- the guide 56 can be rotated about this axis by a hydraulic cylinder 57.
- On the mast guide 56 and the feed mast 34 is supported for displacement in its longitudinal direction.
- the mast guide 34 mainly consists of an elongated plate 58 with fittings 59 bolted thereto, which engage flanges of the mast in the manner of a dovetail guide.
- the position of the mast in the guide can be adjusted by means of the elongated hydraulic cylinder 60 which is mounted on the mast near the top and is connected to the guide 56 by its piston rod 61 and which presses the lower end of the mast with its fixation point 62 against the ground so as to transmit the weight of the drill rig during operation.
- the feed mast 34 is shown as consisting of two channel sections with the webs facing each other, and the operational devices for the drill rod include a drive unit 64 which is mounted near the lower end of the mast and may consist of a compressed air motor 65 with reduction gear for driving an endless feed chain which extends along the mast and is fixed to a working unit 66 with percussion and rotation devices for the drill rod 63.
- a drive unit 64 which is mounted near the lower end of the mast and may consist of a compressed air motor 65 with reduction gear for driving an endless feed chain which extends along the mast and is fixed to a working unit 66 with percussion and rotation devices for the drill rod 63.
- a mobile drill rig comprising two spaced track structures each with a caterpillar track, a chassis, means supporting said chassis from said track structures, a boom having opposite ends, a turntable supported on said chassis for rotation about a substantially vertical axis, means connecting one end of the boom to the turntable for pivotal movement about a horizontal axis, a guide means pivotably connected to the other end of the boom, a drill mast supported in said guide means for longitudinal adjustment thereon, said means supporting the chassis from the track structures comprising two hydraulic cylinders coupled to respective track structures, and aligned in the transverse direction relative to said track structures to serve to provide a mechanical load supporting connection between the chassis and the track structures, said track structures each including separate drive means, said cylinders being supported by the track structures such that the track structures can be pivotably moved relative to one another about a transverse axis concentric with said cylinders and located approximately midway of the length of the track structures, a common piston rod for said cylinders, and means coupled to said common piston rod and said turntable for rotating the
