DEVICE FOR CONNECTION TO THE JOINT BODY OF THE VEHICLE

The invention relates to a device as defined in the preamble of claim 1.

A device for connecting a work vehicle articulated boom comprising a first boom arm articulated at one end for pivoting to a work vehicle and an outer second boom arm pivotally pivoted to the other end of the first boom arm, a quick release device pivoting about a horizontal pivot axis , and power means for pivoting the first, second boom arms and the quick coupler relative to the work vehicle and to each other. The device includes a mounting frame 15 with fasteners for attachment to the quick release device. The scope of the articulated boom of such a conventional work vehicle, such as an excavator, is usually so limited that the work vehicle is not suitable for use, e.g. In order to achieve a sufficient dimension, it is not expedient to drive the excavator on a sloping roadside, which may sometimes also be too steep, but preferably from a flat road surface. For example, in order to perform the leveling of small ramps quickly, it would be advantageous for the work vehicle to be able to drive the road back and forth while performing leveling and earthmoving work. This is not possible with known devices.

The object of the invention is to eliminate the above-mentioned drawbacks.

In particular, it is an object of the invention to provide a device for connection to the end of an articulated boom of a work vehicle, which device substantially and sufficiently increases the dimension of the boom to allow e.g. road finishing work while the work vehicle can be driven along the road. It is a further object of the invention to provide an accessory to which any known tool can be connected.

The device according to the invention is characterized by what is stated in claim 1.

According to the invention, the device comprises an adjustable, telescopic extension boom connected to a mounting frame; an implement pivotally articulated to the end of the overhang boom, and a first power member, such as a hydraulic cylinder, arranged between the overhang boom and the implement to pivot the implement relative to the overhang boom.

An advantage of the invention is that by means of the telescopic extension boom, the extent of the articulated boom of the work vehicle can be considerably extended and any suitable tool can be connected to the end of the boom. Together with the mobility of the articulated boom of the work vehicle, the 20 boom greatly expands the possibilities of using the work vehicle in various jobs. Due to the increase in dimension, it can be used e.g. in various lifting work: for example, a long object can be attached to the end of the boom, which can be hung in an upright position. An example of 25 is the so-called handling of the drum opening device for which the lifting height of the articulated boom of an ordinary excavator without an accessory is not sufficient.

In one embodiment of the device, the device comprises a second force member acting on a pressure medium, such as a hydraulic cylinder, e.g. a double-acting hydraulic cylinder, for shortening and lengthening the telescopic boom.

In one embodiment of the device, the fastening body comprises a first body part which is fastened to the fastening device by fastening means 35 and a second body part pivotally articulated relative to the first body part so as to be pivotable to the first articulated axle.

Around a joint axis perpendicular to the direction of the pivot axis; and the device comprises a pressure medium-acting third force member, such as a hydraulic cylinder, e.g. a double-acting hydraulic cylinder, for pivoting the first body part and the second body part relative to each other. With this arrangement, the extension boom with its tools can be tilted to the desired angle so that, for example, in leveling work on a roadside ramp, the leveling device 10 used as a tool at the end of the extension boom can be turned according to the ramp inclination.

In one embodiment of the device, the overhead boom comprises an elongate first boom beam connected to the second body portion and an elongate second boom beam adapted to move within the first boom beam; and the second force member is arranged to operate between the first boom beam and the second boom beam to telescopically extend and shorten the overhang boom. The beam beams 20 are preferably box beams of rectangular cross-section.

In one embodiment of the device, a sleeve-like guide member is attached to the second body part, on which the first boom beam is supported to be movable; and the device includes a pressure medium-operated fourth force member, such as a hydraulic cylinder, e.g., a double-acting hydraulic cylinder, for moving the first boom beam relative to the guide member in the longitudinal direction of the overhang boom. This arrangement further increases the range of adjustment of the overhang boom.

In one embodiment of the device, the tool is articulated to the end of the second boom beam to pivot about a second pivot axis transverse to the longitudinal direction of the second boom beam.

35 In one embodiment of the device, the implement is guided to pivot about a second pivot axis by a four-joint mechanism.

4 101001

In one embodiment of the device, the implement comprises a first implement body articulated to the end of the second boom for pivoting about a second articulated shaft; a second tool body to which 5 tools are attached; and a rotating device arranged to rotate the second means body about an axis of rotation which is perpendicular to the second articulated axis. The rotating device allows the tool to be rotated to the desired working position.

10 In one embodiment of the device, the device is connected to the articulated boom of an excavator in place of a bucket or other known tool; and the fastening mounts are elements known per se for a standard quick-release fastener known per se.

15 In one embodiment of the device, the tool tool is an earthmoving tool, such as a bucket, push plate, leveling plate, or a combination thereof. The tool may include a soil compaction device, such as a vibrating device, e.g. a vibratory roller. The tool can also be a clearing device, such as a cutting device 20 for cutting vegetation, e.g. a cotyledon, grass, etc., in particular a cutters equipped with a power device.

The invention will now be described in detail by means of application examples with reference to the accompanying drawing, in which Figure 1 shows an embodiment of a device according to the invention mounted on an excavator articulated boom, Figure 2 shows a side view of Figure 1 without a tool, Figure 3 shows section III-III of Figure 2, Figure 4 shows a side view of a part of the device of Fig. 2 with a tool connected to the end of the extension boom, which is a leveling device turned to its first extreme position, Fig. 5 shows the device of Fig. 4 with the leveling device turned to its second extreme position, and 5 101001 Fig. 6 shows a part of Fig. 2 devices, corresponding to Figures 4 and 5, and with a bucket as a tool.

Figure 1 shows a wheeled excavator with a rotating boom base and a ni-5 articulated boom 1 comprising successively articulated boom arms 5, 6 rotatable relative to each other by force members 2, 3, 4. The articulation of the articulated boom 1 to the end of the outer boom arm 6 is 7, to which, for example, an excavator bucket or other device equipped with similar quick-attaching members can normally be attached. The fastening device 7 is articulated for pivoting about a horizontal pivot axis 8. The boom accessory attached to the standard quick release device 7 has a mounting frame 9, 15 with mounting members 10 for mounting to the mounting device 7. The device has a hydraulically adjustable, telescopic extension boom 11 connected to a mounting frame 9. The tool 12 is pivotally articulated to the end of the extension boom 11. The first force member 13, which is a double-acting hydraulic cylinder, is arranged to act between the extension boom 11 and the implement 12 to rotate the implement relative to the extension boom.

The extension boom 11 increases the dimension of the machine in the example of Fig. 25 1 by about 3 to 5 meters. When installed, for example, in an 18 tn wheeled excavator according to Fig. 1, its dimension with the overhang boom 11 is about 14 meters. When the machine is on a level surface, the stability of the machine is sufficient without excavation supports, which makes it possible to work so that the machine is driven on the road during work, which considerably speeds up, for example, the ramp-making work according to Fig. 1.

Referring now to Figure 2, the device includes a pressure medium actuated second power member 14, which is a two- to 35-acting hydraulic cylinder, for shortening and lengthening the telescopic overhead boom.

As can also be seen in Figure 3, the fastening frame 9 with which the boom device can be fastened to the articulated boom of the work vehicle comprises a first body part 15 fastened by fastening means 10 to the fastening device 5. Further fastening frame 9 comprises a second body part 16 pivotally articulated first frame with respect to the part 15 so that it can be rotated around the first pivot shaft 17 by a third force member 18, which is a double-acting hydraulic cylinder. The articulated shaft 17 is perpendicular to the direction of the pivot shaft 8 (see Fig. 1). Figure 3 further illustrates the tilted positions of the extension boom 11, drawn in dotted lines. Preferably, the second body part 16 can be tilted with respect to the first body part 15 up to about 40-45 °, whereby the machine can perform and maintain very steep road ramps.

As further shown in Figure 2, the end boom 11 includes an elongate first boom beam 19, 20 connected to a second body portion 16 of the mounting frame 9. The elongate second boom beam 20 is adapted to move within the first boom beam. The second force member 14 is arranged to operate between the first boom beam 19 and the second boom beam 20 to telescopically extend and shorten the outermost boom 11. Attached to the second frame part 16 is a sleeve-like guide member 21 on which the first boom beam 19 is supported to move. The pressure medium-operated fourth force member 22, which is a double-acting hydraulic cylinder 30, moves the first boom beam relative to the guide sleeve 21 in the longitudinal direction of the overhang boom 11.

Figure 2 does not show the tool at the end of the second boom 20, but Figures 4 and 5 show an example of a tool 12 in which the tool 27 is a leveling device 35 seen from the side in Figures 4 and 5 with the leveling and buffer surfaces 30, 31, 32 and 33 of the leveling device in a position perpendicular to the longitudinal direction of the second boom, 101001 beam 20, and the plane of the image. The tool 11 is articulated to the end of the second boom 20 by a four-joint mechanism 24 so as to pivot about a second articulated shaft 23 5 transverse to the longitudinal direction of the second beam. The four-joint mechanism, i.e. the articular square mechanism, includes a second articulated shaft 23 at the end of the second boom 20 and a joint 34 at a distance from the articulated shaft at the end of the boom beam 20. The portion between the joints 23 and 34 can be considered a fixed member 10 of the mechanism. This body has a pivot lever 35 articulated by a joint 34, which is acted upon by a hydraulic cylinder 13. An end lever 37 is articulated at one end of the pivot lever 35 by a hinge 36, the other end of which is articulated by a hinge 38 to the first tool body 25 of the tool 15. The hinge 38 is located in the first tool body 25 at a distance from the pivot shaft 23.

The tool 12 includes a first tool body 25 articulated to the end 20 of the second boom 20 for pivoting about a second pivot shaft 23. The tool further comprises a second tool body 26 to which a tool 27 is attached. The rotating device 28 is arranged to rotate the second tool body about an axis of rotation 29. The axis of rotation 29 is perpendicular to the second articulated axis 23 25. Figure 4 shows a dotted line equalization device with a rotating device 28 rotated by way of example 90 ° with respect to a position drawn with a solid line. Preferably, by means of the rotating device 28, the tool 12 can be rotated a full 360 ° and locked by a locking device 39, which, for reasons of weight saving, is preferably pneumatically operated, to any desired angular position.

Figure 6 shows a bucket 27 of the tool 12 as a tool. Equipped with a bucket, the device can be used, for example, for clearing ditches and earthmoving.

35 A ground compaction device, such as a vibrating device, e.g. a vibratory roller, can also be connected to the end of the extension boom 11. A clearing device, such as a cutting device for cutting vegetation, e.g. a cotyledon, grass, etc., can also be connected to the end of the extension boom 11, in particular a cutters equipped with a power device.

The invention is not limited to the application examples presented above only, but many modifications are possible while remaining within the scope of the inventive idea defined by the claims.
