l Claim.
This invention relates toimountings, and more particularly to a portable mounting for rock drills o' the drifter type;
One object ofthe: inventionis to enable a roel; drill to. bef expeditiously' and; conveniently placed inv position with respect to thematerial intended to-V beZ drilled.
Another object is. toi construct a light weight portable: mounting that may be conveniently moved about vwith a minimum of effort.
Another object isto construct a rugged and durable mounting, the parts ofv which may be quickly and: safely adjusted: relatively to each other toplace the rock drilling mechanism in a desired drillingposition.
'Other objects will be in part obvious and in part pointed out hereinafter.
In the drawings accompanying this specication and in which similar reference numerals refer to similar parts,
Figure l is; a sidef elevation of a mounting constructed in accordance with the practice of the invention and a rook drillingmechanism carried by the mounting,
Figureiz is an end elevation of' the mounting,
Figures 3 and, 4 are. transversevr viewsv taken through. Figure, 1- onv the lines- 3-3 and 1 -4, respectively;v
Referring: more. particularly t the drawings, the-mounting, constructed in accordance withthe practice or' the invention and designated in'its entirety by; comprises. a support member 2| which consists of .a horizontal tubular bar 2,2 and legs 23 extending laterally thereof. The legs 23 may be formed integrally with the bar 22 or, as indicated at 24, be welded to the bar, and at their lower ends are brackets 25 having spindles 26 for wheels 21 upon which the mounting may be wheeled from one drilling site to another.
The rock drilling mechanism is arranged upon the bar 22. It consists of a guide frame 28, a rock drill 29 slidable on one side of the guide frame for actuating a working implement 30 and a winch 3l on the opposite side ofthe frame 28 for moving the rock drill along the guide frame, a cable 32 leading from the winch to the rock drill being entrained over a sheave 33, at the upper end of the guide frame, and fastened to the rock drill.
The guide frame 28 is secured to the bar 22 by a clamp 34. The clamp 34 may be of a well known type that is both rotatable on and shiftable endwise of the bar 22 and will permit of endwise .adjustment of the guide frame in the clamp, and the clamp has a swivel connection q 35 is of V-shape.
with the' guide frame to enable; the.: rook; drilling mechanism to be conveniently placedin adsired position; with respect toy the rock.
In order; to hold the support member- 2| an;
upright position, and in. the inclinedA positionsthat may be necessary to locate the; rock drill correctly; with the respect to thework, the supporting. member is-provided with; a brace 35 that is piyotally connected to the bar 22. The brace It has a pair of tubular arms 3,'5'that are joinedY together at their outer ends by a bolt 3l, extending through, plates 38 having stemsSS. lying-in the'end portions ofthe arms 36V tol which they maybe fastened in anysuitable manner.
One of the; plates 3.8 isv shownashaving a projectilonAdandA an eye-bolt 4|- is arranged therein for holding an anchor pin 42. The anchor pin extends through, the eye I3l of the bolt 4I and iedrawninto frictional engagement with a washer 44;, located; between the eye of the; bolt and the projection 4,0, byV a nut 45,. The anchor pin, kas is customary, is pointed at its lower 'end for engagement with the surface upon which it rests.
,.The plates 3,3 also serve as ai support for a handle c6; of 4a well known construction including a bolt 4l that projects from'A the opposite sides of; the plate 38,` and. has grip members 48 on its projecting portions.
The, pivotal connect-ions between the arms 3E andthe support member 2l are in the form of cone clutchesA and servef as brakesy to; control therate of speed at which the brace may swing relatively to the support member and serve also as locks to lock the brace immovably to the support member. To this end the arms 36 are provided with hubs 49 that lie coaxial with the bar 22 and have sockets 5l!v of coniform shape to receive correspondingly shaped end portions 5l of the bar 22 lying outside the points of juncture of the legs 23 with the bar. The hubs 49 and the ends 5l are perforated axially to receive a rod 52 that extends entirely through the hubs .and the bar. Both ends of the rod 52 are threaded for the accommodation of nuts 53 that act against the outer ends of the hubs 49 to press their coniform surfaces against those of the ends 5l In practice, one of the nuts 53 may be manipulated to effect the decrease of friction between the coniform surfaces and the bar 22, together with its load, may be lowered gradually and with a minimum of effort to place the rock drilling mechanism in a new drilling position.
Although the rate and the degree of pivotal movement of the support member and the brace relatively to each other may be nicely controlled by means of the nut 53, it is preferred that additional means be provided to assure against the abrupt collapse of the mounting in the event that the nut 53 is inadvertently turned to a position that will permit free pivotal movement between the hubs 49 and the coniform ends 5I. To this end a stop member 54 is disposed upon one of the hubs 49 for engagement with one of the legs 23 of the support member.
The stop member 54 comprises a split collar 55 that encircles the hub 49, preferably in the transverse plane of the socket 50. On opposite sides of the gap in the collar 55 are lugs 56, and a bolt 51 extends through the lugs and has a nut 58 acting against one of them for clamping the collar securely to the hub 49. On one of the lugs 56 is an arm 59 that extends diagonally of the collar into the path of movement of the adjacent leg 23 which it may engage to limit the degree of inclination of the legs 23 relatively to the brace 35.
The collar 55 is readily rotatable on the hub, and the arm 59 may, therefore, be conveniently adjusted to diiferent positions to act as a stop for the adjacent leg 23 and thereby prevent the support member 2l and the brace 35 from assuming incorrect angular positions relatively to each other for a desired setting of the drilling mechanism.
Preferably, anchor pins 42 are also arranged on the legs 23 to assist in maintaining the mounting stationary on the surface supporting it. These pins are clamped firmly to the legs 23 by suitable clamping devices 69 that are similar in all essential respects to that described in connection with the anchoring pin 42 at the handle-end of the brace 35.
In the operation of the device, and assuming that the anchoring pins 42 on the legs 23 have been moved out of contact with the ground, the `free end of the brace is lifted by means of the handle 45 and the mounting may then be wheeled to the desired location. The handle-end of the brace is then anchored securely by forcing the pointed end of the pin 42 into the rock or material supporting the mounting.
Thereafter the stop member is rotated about the hub to place 'the arm 59 in approximately the correct position for engagement with the adjacent leg 23 in the positions which the support member 2| and the brace l35 will assume in the new setting, and the collar is again clamped xedly to the hub 49. The nut 53 is then manipulated to maintain only braking friction between the hubs 49 and the ends 5I and the wheels 21 will then roll along the ground and permit the bar to move downwardly until the leg 23 contacts the arm 59. The nut 53 is then again rotated to lock the brace to the bar and the anchoring pins 42 on the legs 23 are driven into the ground to hold the mounting stationary.
Thus, as will be readily apparent from the foregoing description, the changes in the angular relationship of the brace to the supporting member 2| may be conveniently and quickly effected, to raise and lower the drilling mechanism, and with a minimum of effort on the part of the operator,
I claim:
In a mounting for rock drills, a horizontal bar to support a rock drilling mechanism, legs integral with the bar, wheels on the legs, a brace for the bar having a pair of arms, coniform surfaces on the arms and on the ends of the bar cooperating with each other to form pivotal connections between the bar and the brace to permit of angular adjustment of the brace relatively to the bar, clamp means on the brace adjustable with respect to the brace and to the legs,A a projection on the clamp means to extend into the path of movement of and engage one of the legs to limit the degree of angular movement of the brace with respect to the bar, a bolt extending through the bar and through the ends of the arms, and a nut on an end of the bolt to engage one of the arms for forcing the coniform surfaces of the arms and the bar into braking and locking engagement 'with each other.
