Description
1326~48 BACKGROUND OF THE INVENTION
FIELD OF THE INVENTION
The present invention generally relates to earth S drilling equipment and more particularly to an apparatus for handling rods in the making or dismounting of a string during a drilling operation. It also relates to a mobile camp provided with the essential boring elements which camp is suitable to be displaced from one drilling location to another.
DESCRIPTION OF THl~ PRIOR ART
The boring of holes through the earth requires the freguent handling of drill rods to be brought to or taken away from a vertical drilling mast, also called tower or derrick, and a rod storage rack to assemble or disassemble them into or from a rod string. Use is made, for this purpose, of rod-handling devices suitable for feeding the rods to the mast from a nearby storage rack and returning them to it from the derrick. Whenever the bore to be drilled, and consequently the mast, is to be inclined, the handling has to be done manually which is of course a tiresome job which may further be dangerous. Indeed, it must be considered that the heavy rods may have approximately 10 feet in length with a diameter of about 2"
to 4". They may further have to be moved on a distance of several feet as well as shifted lengthwise, that is lifted and lowered in order to place them and remove them on and from the mast and coupled and uncoupled to the drill head.
This manual operation, as will be gathered, is not very productive.
Also, the existing drilling equipment is designed to be rigged up on the drilling site and it has to be dismounted, at least in part, whenever a new drilling 1326~48 location is selected.
SUMMARY OF THE INVENTION
An object of the invention is to avoid the above noted drawbacks by providing a rod-handling apparatus capable of gripping a drill rod and move it angularly in a vertical plane so that it may reach the angular position of the drill mast so that it may be applied to it.
Another object is to provide such an apparatus allowing the rod to be moved lengthwise so that it may be adjusted to be coupled to the drill head of the mast.
Yet another object lies in providing an apparatus of the above type which may ~ransport the rod between a nearby storage rack and the mast.
Still another object of the invention resides in providing a mobile drill camp having an enclosure capable of containing a drill mast pivotable in a vertical plane; a storage rack for drill rods and a rod handling apparatus of the aforesaid type.
More specifically, the invention essentially proposes an apparatus for handling elongated rods which comprises a horizontal stationary base over which is mounted a support member movable in a first direction along the base Z5 and, over the support member, an elongated rod-handler arm movable in a second direction normal to the first one. The arm is provided, at one end, with a rod handler capable of pivoting in a vertical plane and provided with a rod-gripping device capable of gripping one of the rods. This latter device is equiped with a mechanism which allo~s the gripping rod to move lengthwise while being gripped. The invention also proposes a mobile drill camp having the above described rod-handling apparatus.

1326~4~ ' DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to Figures 1 and 2, there is shown a mobile camp 1 including a sleigh-like vehicle 3 with xunners 5 so that it may be moved over the ground when hitched to a tractor by a towing structure 7. The vehicle may of course alternatively be wheel-mounted.
Vehicle 3 has a floor platform 9 and an upright frame 11 rising from the floor, defining an enclosure 13 suitable to contain a magazine or storage rack 15, on one side of the vehicle center line 17, and a rod-string handling mast 19 extending up from the floor platform along the center line 17. The enclosure is also meant to contain other sundry equipment so that the camp may be said to be self-contained and thereby moved from one drilling site to another without having to dismantle the drill mast 19. The latter has one end pivoted, at 21, on a floor bracket 23 and made to swing in a vertical plane by a hydraulic power jack 25. The construction should be such as to allow the mast 19 a total swing of about 75 in the vertical plane, i.e., between 17 and 92, for instance. In the low position, the mast and other equipment in the enclosure 13 should be within the height permissible under official road regulations. This applies to the rods 27 in the rack 15 which would then be made to lie over the floor platform 9.
In the rack, the rods are slightly inclined so as to form an angle of 80 with the floor of the platform as shown in figure 2. The mast 19 has the usual drill head 29 movable along it and serving to rotate the rod string and force it down into the ground; the lowermost rod being of course provided with a drilling tool, such as trepan. Finally, the ' enclosure 13 defines a top opening circumscribed by a horizontal chassis 31 of the frame 11.
The apparatus for handling the rods essentially !
1326a4s comprises a horizontal stationary base 33 secured to the side members of the chassis 31. Mounted on the base 33 for displacement transversely of the center line 17, in a first direction indicated by arrow a, is a support member 35 in the form of a platform. An elongated rod-handler arm 37 is provided on the support platform 35 for displacement lengthwise in a second direction, indicated by arrow b, normal to the first direction, that is parallel to the center line 17. Provided at the end of the arm 37 away from the support member or platform 35, is a rod-handler 39 of which the lower end is pivoted, a~ 41, to the arm 37, so that it may swing in a vertical plane along arrow _; the swing axis being perpendicular to the arm's longitudinal axis, i.e. perpendicular to the second direction _. The apparatus of the embodiment further includes a pair of rod-gripping devices 43 spaced from one another and so as to swing in the vertical plane as the whole rod-handler 39.
Finally, means are provided on each gripping device 43 for moving the rods lengthwise; such means being detailed hereinafter with respect to the description relative to Figure 4.
With the above arrangement, it will be appreciated that a rod 27 may be gripped by the rod-handler 39 from the storage rack 15; moved along arrow _ to be placed facing the drill mast 19; pivoted to the same angle as the mast, along arrow c; moved along arrow b so that it may operatively be connected with it and finally moved down to be coupled with the drill head 29. The reverse operation is of course also ; possible.
Referring to figures 3 and 4, it will be seen that the rod handler 39 includes a central square post 45 having a longitudinal axis lying in the aforesaid vertical plane and that the two rod-gripping devices, only partly detailed ; in figure 3, are spaced along the post so as to grip the rod 1326~8 27 at two locations thereon.
As the two devices are identical, only one need be described which is particularly shown in Figure 4. It is seen to comprise a first jaw 47 fixed to and projecting laterally of the post 45; having an inwardly curved face 49.
It also has a second jaw 51 projecting laterally of the post 45 but pivoted ~o it, at 53. Its inner face 55 is concave like that of face 49 of the first jaw 47. Boths jaws are hollow so as to include concave walls forming the inner faces 49, 55, and having roller openings. A driving roller 57, having a roughened concave periphery, is housed in the first jaw 47 and projects slightly, at 59, out through the jaw's opening. Similarly, the second jaw 51 has an idler roller rotatably mounted within it and having a concave periphery projecting slightly out through the jaw's opening, as at 63. The driving roller 57 is rotated by a hydraulic motor 63, mounted on the jaw 47. When the jaws 47, 51, close in on a rod 27, the latter is firmly gripped between the rollers 57, 61, and may be difiplaced axially by the action of the driving roller 57. The roughened surface of this driving roller 57 may be obtained by a series of ribs extending parallel to the rotation axis of the roller.
The second jaw 51 is pivoted, at 53 as aforesaid, by a bell-crank lever 65 of which the apex is pivoted at 67 to the outer end of the jaw. Lever 65 has one section 69 inwardly curved at 71 and positioned for drawing a rod to be gripped between the cooperating jaws 47 and 51. It also has a driving section 73 of which the free end is connected to a rod 75 of an extensible power jack 77 pivoted to the free end of a bracket 79 solid with and projecting laterally of the post 45 on its side which is opposite to its other side having the jaws 47, 51. The pivoting motion of the lever 65 is limited by a first stop lug 81 solid with and projecting up from a finger 83 extending from the jaw 51 and by a ~ 3 2 ~ 8 second stop lug 85 projecting up from the said jaw 51 but on the side of the driving section 73 opposite to the side of the lug 81; both lugs 81 and 85 being thus on the pivot path of the lever driving section 73.
When the jack 77 is extended, the bell-crank lever 65 first pivots clockwise around axes 67 to drive a rod between the two jaws 47 and 51 until its driving section 73 hits the stop lug 81 at which the jaw 51 is forced to pivot also clockwise to bring the gripped rod against the first jaw 47. When the jack 77 is retracted, the lever 65 rotates counterclockwise untils its driving section 73 comes against the stop lug 85 to bring the jaw 51 to rotate counterclockwise and release the rod.
To assist in dislodging a rod 27 from the stack lS stored in the rack 15, the fixed pivot jaw 47 is provided with a straight thin guide finger 87 projecting outwardly away from the jaw 47 and adapted to be inserted between two adjacent rods 27 and cooperate with the curved lever section 69 in drawing a rod between the jaws 47 and Sl.
The rod-handler 39 is made to pivot about the axis 41 (figures 2 and 3) by means of another extensible hydraulic power ~ack 89 connected to the rod-handler arm 37, through a bracket 91, and to another bracket 93 of the handler post 45. The angle of swing of the rod-handler 39 is adjustably controlled by a thin roà 95 pivoted at one end to the bracket 93 and slidable through a rockable block 97 (figure 3) at the top of the bracket 91. Stop nuts 99, 101 (figure 5), are screwed along the rod 95, on either side of the bracket 91 to provide the adjustable swing.
Referring now to figures 3, 5 and 6, it is seen that the rod-handler arm 37 is made up of a pair of parallel channel members 103, 105, having their webs upright and their lower flanges slidably guided over the support platform 35 by a pair of guide angles 107, 109 secured to i32~8 the platform 35, as by welding, on either side of the channels. The latter are held in parallelism by transverse brace plates 111, 113, at either end; by the axle structure 41 and by the bracket 91. Movement of the rod-handler arm 37 in the second direction aforesaid is obtained by a power jack 115 of which the rod is connected to the transverse plate 113 and the cylinder connected to a bracket 117 fixed to and upstanding from the support platform 35 between the channel members 103, lOS. As will be appreciated from figure 5, extension of the jack 115 will move the rod-handler arm 37 leftward and the contraction will move it rightward, in the second direction along arrow b, in figures 1, 3 and 5.
The means responsible for moving the support platform 35, and thus the arm 37 in the direction _ in figures 1, 3 and 7, are of a similar construction.
Referring to figures 3, 7 and 8, channels 119, 121 and 123, with webs upright, have their lower flanges secured to the stationary base 33, itself fixed at his ends to the chassis 31 at the top of the frame 11 (figures 1 and 2). The support platform 35 has two pairs of guide angles 125, 127, ; on its underface which guidingly receive the upper flanges of the channel 121, 123. A power jack 129 is housed between the channels 119, 121; having its rod mounted on a braket 131, fixed to and downwardly projecting from the support platform 35 and having its cylinder supported by a cross-plate 133. Figures 7 shows that extension and contraction of jack 129 moves the support platform 35, and the rod-! handler arm 37 thereon, in the first direction a aforesaid.
