Description
- The present invention is related to an industrial vehicle, of the self-propelled type, provided with tools useful for carrying out the operation foreseen for it.
- Examples of industrial vehicle falling within this definition are, for instance, a dumper provided with a mechanical bucket and a hopper, a fork lifter, an excavator, an articulated crane, a lifting platform and so on.
- Several embodiments of vehicles as depicted above are known, usually comprising a self-propelled chassis, e.g. crawler-mounted, and various kind of tools mounted above the chassis.
- By way of example, a self-loading dumper as previously defined is provided with a loading bucket, mounted on articulated arms, and a hopper, and the main feature thereof is its capacity to move an load the hopper with its own bucket.
- For this reason, this kind of machine, widely used in the field of earthwork, is highly considered for its flexibility in operation. Therefore, several self-loading dumpers exist, with different sizes, suitable for different purposes.
- However, the limit in the use of the self loading dumper lies in its capacity of loading only in an area localized in front of the hopper according to the direction of travel. Therefore, for loading material which is not placed just on its track, the dumper is forced to move itself, to be placed in a loading position, through even complicated maneuvering, possibly on a rough and slope grounds.
- The same problem may be encountered also in other typology of vehicle.
- With reference to lifters, they are generally provided with forks, hooks, blades apt to work in front of the vehicle, which has the capacity to rotate as a whole and to follow a curved track.
- Such a configuration allows an eased use in storing areas and depots, where the loads are arranged in an ordered manner, with corridors and spaces allowing the lifter to move so as to place itself with said loads in a frontal position for the lifting thereof.
- However, when the spaces are narrower, more complex systems are used, e.g. travelling cranes, provided that the vehicle cannot rotate in a narrow space to lifter and to transport the load.
- These inconveniences are more felt when the vehicle, for practical reasons, are crawled-mounted instead of wheel-mounted, and with the operator positioned on board.
- The technical problems underlying the present invention is to provide a self-propelled vehicle allowing to obviate to the drawbacks mentioned with reference to the prior art.
- Such a problems is solved by a self-propelled vehicle as above specified, comprising:
- a self-propelled chassis, on which a tool support plate is placed; and
- drive means, placed between the chassis and the support plate, apt to rotate the support plate.
- The main advantage of the self-propelled vehicle according to the present invention lies in allowing the rotation of the whole rotating plate which can support the operative tools, separating such a rotation from the whole vehicle.
- The present invention will be hereby described according to a preferred exemplificative embodiment thereof, given by way of a non-limiting example, with reference to the annexed figures, wherein:
-
figure 1A shows a partial exploded perspective view of a self-propelled vehicle according to the invention, in particular a self-loading dumper; -
figure 1B shows a further perspective view of the vehicle offigure 1A ; -
figure 2 shows a side orthographic view of the vehicle of the preceding two figures; -
figure 3 shows a perspective view of the vehicle of the preceding figures, in a complete assembly; -
figure 4 shows a perspective view of a second vehicle example, in particular a self-propelled lifter; -
figure 5 shows a side orthographic view of the lifter offigure 4 ; -
figure 6 shows a plan view of the lifter offigures 4 and5 , in different operative positions; -
figure 7 shows a side orthographic view of a telescopic arm excavator according to the present invention; -
figure 8 shows a side orthographic view of a lifting platform according to the present invention; and -
figure 9 shows a side orthographic view of a crane according to the present invention. - With reference to
figures 1A, 1B ,2 and3 , a self-loading dumper, shown with thereference number 1, will be described in the following, as an example of self-propelled vehicle according to the invention. - It is mounted on
crawlers 2 and it is provided with ahopper 3 and a front bucket 4 mounted on a pair ofarms 5. - Moreover, it is meant to be controlled by an operator placed in an
operating cab 6 by means ofcontrols 7. - Crawlers 2 support a self-propelled
chassis 8, onto which thecab 6 is provided, and comprising a motor and all the controls of hopper and bucket. - Frontally, opposite the
cab 6, thechassis 8 supports asupport plate 9 entirely resting above thechassis 8. Theplate 9 is horizontally disposed and it is constrained to thecab 6. - Underneath it, the
dumper 1 comprises drive means, placed between thechassis 8 and thesupport plate 9, apt to rotate thesupport plate 9. In particular, said drive means comprises afifth wheel 10 fixed to theplate 9 by means of crown-disposed bolts. Thefifth wheel 10 is rotated by means of a motor-drivenpinion gear 11. - The
plate 9 receives saidhopper 3, and the respective controls thereon, so that thehopper 3 can be rotated relative tochassis 8 and crawlers, opposite to the operator. - In the present exemplificative embodiment, the
plate 9 is provided with supportingprojections 12 at the side edges thereof, supporting the articulatedarms 5 and the controls thereof, respectively. Accordingly,arms 5 and loading bucket 4 can rotate together with thehopper 3, thus always remaining in an optimal position for the material loading. - Anyhow, it is intended that the arms could be directly articulated to the
hopper 3 or, alternatively, to thechassis 2. - In the present exemplificative embodiment, the
arms 5 are optimally placed for being controlled in a position in which they provide the dumper a balanced configuration, even when thehopper 3 is rotated. - As in the present example, they could be telescopically extensible.
- The
fifth wheel 10 rotation axis A is substantially centered on theplate 9, in a vertical position. - It is intended that the shape of the hopper and of the bucket could be varied as preferred, in order to satisfy any operative requirement.
- With reference to figures from 4 to 6, in the following it will be described a second example of self-propelled vehicle according to the invention, in particular a crawlers-mounted self-propelled
lifter 1. - In the following, components common to both examples will be shown with the same reference numbers.
- Crawlers 2 support a self-propelled
chassis 8, onto which thecab 6 is provided, and comprising a motor and all the controls of device for grasping, lifting, and/or movingloads 3A, provided on thechassis 8 opposite thecab 6. -
Such device 3A comprises a telescopicallyextensible arm 5, formed by twoparts support plate 9 in correspondence of ahinge structure 5c. - On its distal end, the
arm 5 has a pair offorks 4a associated to a stoppingbulkhead 13. - The
forks 4a are of the type apt to lift standard pallets. Nevertheless, the device for grasping, lifting, and/or movingloads 3 could comprise any other loading implement. - In order to simplify loading and unloading,
forks 4a andbulkhead 13 are articulated at thetelescopic arm 5 distal end, and they can be controlled in their rotation above an horizontal axis, i.e. ahinge 15 onto which suitable actuators are mounted (not shown). - Underneath the
plate 9, thelifter 1 comprises drive means, apt to rotate thesupport plate 9. In particular, said drive means comprises afifth wheel 10 fixed to theplate 9 by means of crown-disposed bolts. Thefifth wheel 10 is rotated by a motor-drivenpinion gear 11. - The
plate 9 receives saidlifting device 3 and the respective controls thereon, so that thehopper 3 could be rotated relative tochassis 8 and crawlers, opposite to the operator. - The rotation axis A of the
fifth wheel 10 is substantially centered to theplate 9, in a vertical position. - In order to avoid the device for grasping, lifting, and/or moving loads to unbalance the self-propelled lifter, in particular when the arm 4 is extended and when it is rotated relative to the frontal position, the
plate 9 has anextension 9a placed according to a configuration opposed to the direction in to which the arm 4 projects. It comprises amobile compensator 14 that is translated according to the position of thearm 5,fork 4a and of the load lifted therefrom. - To this regard, the
compensator 14 could be extensible. - In this way, the
lifter 1 will not be allowed to tilt due to the laterally lifted weight. - It is intended that shape of the device for grasping, lifting, and/or moving loads could be varied as preferred in order to satisfy any operative requirement.
- With reference to
figure 7 , the vehicle, analogous to the preceding ones, comprises a lifting device 3a, the lifting member thereof being formed by abucket 4b articulated to a telescopicallyarm 5 distal end. - The
bucket 4b can thus be operated in its rotation above an horizontal axis, i.e. ahinge 15 in correspondence of which suitable actuators (not shown) are mounted, for simplifying the loading of the material to be displaced. - According to an analogous embodiment, the vehicle of
figure 8 is provided with a telescopic arm supporting alifting platform 4c, also articulated to thearm 5 distal so that it can be always maintained horizontal. - The
platform 4c can be formed by a safety cage. - With reference to
figure 9 , a self-propelled vehicle analogous to the preceding ones, comprises, at thetelescopically arm 5 distal end, a hoist 4d provided with ahook 16 connected to acable 17 end. The hoist 4d could be obviously also replaced by a winch or by any other lifting member. - In each described examples, the operating
cab 6 is disposed on thechassis 8 and not on therotating plate 9. Nevertheless, according to a modification of the invention, thecab 6 could be disposed above theplate 9 and together rotated, so that the operator is always directed towards the implemented mounted on the vehicle. - In this case, the compensator could be mounted at the back of the operating cab, and could be extensible rearwards, with an improved efficiency thanks to the rocker arm accordingly defined.
- The distance of the balance weight at the vehicle center could be manually modified by means by means of an automatic servomechanism, for enhancing balancing momentum.
- Moreover, It is intended that, in case, any of above described vehicle could be provided with stabilizing feet. Moreover, they can be provided with an universal quick coupling for a quick changing of implement at the arm.
- Furthermore, the crawler mounted vehicle could be of the fixed track-gauge type, variable track-gauge type or variable and/or enlarged track-gauge type.
- To the above-described self-propelled vehicle a person skilled in the art, in order to satisfy further and contingent needs, could effect several further modifications and variants, all however encompassed in the protective scope of the present invention, as defined by the appended claims.
