I NVE NTORS BY MUNSON & FIDDLER 1 MOBILE, ROCK DRILL SUPPORTING RIG This invention relates to a mobile, rock drill supporting rig which comprises an operators platform.
Previous drill rigs of this type are disadvantageous in that the vibrations, caused by the rock drill or drills during drilling, are transferred to the platform and further to the operator being on the platform. Those vibrations cause considerable physical strain on theoperator and are particular serious in the case the rig is provided with two or more rock drills.
The main object of the invention is to solve this problem by arranging the platform separable from the rig chassis, so that the platform can be isolated from the chassis during drilling.
An embodiment of the invention will hereinafter be described in detail with references made to the accompanying drawings, wherein FIG. 1 is a side elevational view of a drill rig according to the invention set up in work position. FIG. 2 is an end elevational view of the rig inFIG. 1. FIG. 3 is a large scale cross section along line III-III in FIG. 1, wherein the platform is resting upon the rig chassis and the lifted up work position of the platform is marked out with dotted lines. FIG. 4 is a cross section through the conical support means taken along the line IV-IV of FIG. 3. FIG. 5 is a cross section similar to FIG. 4 showing a prismatic support means.
The mobile rig shown in FIG. 1 and 2 consists ofa rig chassis 2 provided with wheels 1. On the chassis 2 there are mounted three rock drill supporting feed bars 3, each provided with a rock drill 4. To establish a rigid set up of the drill rig in its working position, it is provided with a number of downwardly extendible support legs 5 preferably consisting of hydraulic jacks. On the rig chassis 2 there is provided a box 6 within which all the main valves for the rock drill functions are arranged. According to the invention the drill rig comprises an operators platform 7. On the platform there is mounted a control panel 8 which supports a number of control valves. These valves are operable by means of levers 13 for manoeuvering of the rig and the rock drills.'On the platform there is also arranged a drill rod rack 14 and a protective roof 9.
The rig chassis and the operators platform 7 are provided with cooperating support means 10 and 11 by means of which the platform is arranged to rest upon the rig chassis in a transporting position.
To isolate the operators platform 7 from the rig chassis, which is subjected to considerable vibrations during drilling, the platform is provided with downwardly extendible support legs 12 preferably consisting of hydraulic jacks. By means of these jacks the, platform can be lifted up so that the support means 10 and 11 are separated and the platform forms a free standing unit to which vibrations of the rig chassis will not be transmitted. In the described embodiment of the invention the support legs consist of hydraulic pistoncylinder units. However, the invention is not limited thereto. Of course, the support legs may consist of other equivalent devices; for example mechanical screw operated jacks. In the described embodiment of the invention, the support legs of the rig chassis as well as the support legs of the platform consist of hydraulic piston-cylinder devices which are all operated from the control panel 8. In order not to make the figures obscure, supply conduits to these hydraulic support legs are not shown.
As being apparent from FIG. 3 the support means 10 and I 1 are provided with slanted prismatic'contact surfaces (see FIG. 5) which will centralize the platform relative to the rig chassis as the former is lowered. The contact surfaces may also be conical as shown in FIG. 4. Moreover, between the rig chassis and the platform there are provided wire straps 15 for limiting the lift movement of the platform above the rig chassis. The height to which the platform is raised above the rig chassis should not exceed the ability of the support means 10 and 11 to restrict sidewise movement of the platform relative to the rig chassis. Should the platform be lifted up too high the bottom edge of the upper support means 10 may pass sidewise past the top edge of the lower support means 11 and bring them out of alignment. Thus, the support means 10 and l 1 may not be able to cooperate as the platform is lowered.
The invention is not limited to the described and shown embodiment but can freely be varied within the scope of the claims.
