Definitions
- TITLE Device for adjusting a tool attached to the end of the arm of a shovel or the like
- the present invention relates to a device for adjusting a tool fixed to the end of the arm of a shovel or the like.
- the arm of a shovel is movable in a vertical plane and the tool which it carries is movable around an axis perpendicular to said plane.
- the axis of its perforating point is movable only in the above-mentioned vertical plane.
- the axis of rotation of the tool is arranged obliquely to the vertical plane. This is the case when, for example, it is necessary to break a rock protruding from one of the side walls of a trench. In this case, the axis of the perforating tip must be inclined relative to said wall.
- the device of the invention which overcomes these drawbacks, is remarkable in that the tool is carried by a shaft, the axis of which is movable in the plane of the arm, said tool being able to be moved axially relative to said shaft, against the action of an opposing spring, and pivot about said axis, means being provided for locking, automatically the tool according to the required inclination.
- the device of the invention comprises two stirrups, one of which is made integral with the usual pivoting support of the arm while the other is made integral with the tool, the branches of the two stirrups being nested and crossed by a shaft, fixed relative to one of said stirrups, which are subjected to the action of a spring tending to move one stirrup relative to the other so as to make the two parts of a member of cooperation cooperate lock that holds the tool at the required tilt.
- the device of the invention is interposed between the tool and the adapter of the quick coupler, one of the two parts, the clip, normally attached to the tool.
- FIG. 1 shows in elevation a rock breaker fixed to the end of the arm d 'a machine through the device of the invention
- FIG. 2 is an elevation view on a larger scale of the device of the invention
- FIG 3 is a vertical sectional view of Figure 2;
- FIG. 4 is a view similar to that 3, showing the possibility of moving the tool axially relative to the arm, or vice versa;
- FIG. 5 is a view similar to that 2, showing a safety device;
- FIG 6 is a sectional view taken along line VI-VI of Figure 5;
- FIG. 7 is a view similar to that 5 corresponding to a characteristic position of the arm and of the tool allowing the displacement of one relative to the other;
- FIG. 8 is a view, in elevation and on a small scale, showing the initial positions of the arm and of the tool before a modification of the inclination of the tool;
- FIG. 9 is the top view of FIG. 8;
- FIG. 10 is a view similar to FIG. 8 showing the position of the arm and of the tool at the end of the adjustment of the inclination;
- FIG. 11 is the top view of FIG. 10.
- the tool B in this case a rock breaker, is fixed to the end of the arm 1 by means of the pivoting support 2 articulated by the shaft 3 on the said arms.
- the arm 1 can be moved in the vertical plane (plane of Figure 1). The operation of the arm 1 therefore makes it possible to move the tool and in particular the axis XXi in the vertical plane.
- the problem posed consists in providing a set of means making it possible to place the axis XXi in an oblique position relative to the vertical plane, to maintain it in this position, to modify the inclination and this, without the driver descending from the craft.
- the tool is articulated on a shaft 4, carried by the support
- the shaft 4 crosses the wings 6-6a and 7-7a of two stirrups, the middle part 8 of one of which is fixed to the support 2 while that 9 of the other is fixed to the tool B. Thereafter, the stirrups will be called: stirrup 8 and stirrup 9.
- the wings 6-6a and 7-7a are nested and the shaft 4 is made integral with the wing 6a.
- the spring 5 is interposed between the wings 6 and 7a, or internal wings, and tends to press one against the other the corresponding wings of the stirrups 8 and 9 as shown, in particular in FIG. 2.
- the spring 5 ensures the cooperation of the members of a locking means opposing the rotation of the stirrup 9. If by an external force one of the stirrups is displaced relative to the other according to the 'axis of the shaft 4, the aforementioned locking is removed and the tool can pivot.
- the aforementioned locking means is constituted by a dog clutch, arranged along the axis of the shaft 4, part of which 10 is constituted, for example, by means of a fixed pinion, carried by the caliper 8, capable of '' mesh with a crown 11 with internal toothing carried by the caliper 9.
- the device which has just been described above is actuated by judicious maneuvers of the arm and of the tool controlled by the driver from the cabin of the machine as shown in FIGS. 8 to 11 which illustrate the operation.
- the spring relaxes and the pinion 10 meshes again with the crown 11 while maintaining the axis of the tool in an inclined position relative to the vertical plane containing the arm 1.
- the invention also provides a means for opposing, in a positive manner, the movement of the stirrups when the tool is in the normal working position as shown in FIG. 1 for example.
- This means will be described with reference to FIGS. 5 to 7. It essentially consists of a pivoting finger 14, articulated by one of its ends on the stirrup 8, by means of a shaft 15, and the l 'other extends to near the wing 7a of the caliper when the tool is in its normal position of use.
- means, such as a stop 16 are provided to limit the pivoting of the finger 14.
- the device of the invention is perfectly compatible with the use of a quick coupler, for this it is sufficient to interpose it between the tool and the adapter of the quick coupler.
- Figures 8 to 11 illustrate this possibility.
