Definitions
- the invention relates to a mobile shovel loader with the features of the preamble of claim 1.
- shovel loaders for example mobile on caterpillars or tires, are known and have a wide range of uses. In particular, these shovel loaders are used to load trucks with soil and building materials. When loading high trucks or large dump trucks, especially with light bulk goods such as coal, coke, wood chips, garbage, etc., shovel loaders with a very large loading height are required. Such shovel loaders have, for example, a shovel pivot point of at least five meters above the level. In order to achieve this loading height, on the one hand there are very large shovel loaders with correspondingly articulated long booms with a corresponding dead weight and high engine output (for example 30 tons dead weight at 300 hp) for loading heavy goods. However, these shovel loaders are too large and too expensive to load light goods.
- the object of the invention is to increase the loading height of a relatively small mobile shovel loader from large series production in such a way that it can be used without compromising the stability for loading high trucks with light bulk goods.
- the shovel loader has an additional boom which is articulated in the manner of a parallel link by means of first links and second links on the extension arm and connects the extension arm and the tool.
- the shovel loader also has means for controlling the adjustment of the additional boom depending on the angular position of the boom arm with respect to the boom pivot axis.
- the additional boom is adjusted from a position folded in on the boom arm at the earliest after the boom arm has passed through its horizontal position with an upward pivoting movement. This ensures that an extension of the overall only occurs above the horizontal position of the cantilever arm. Conversely, it is of course also ensured that when the cantilever arm is pivoted downward, the additional cantilever arm is completely folded in again at the latest before the cantilever arm passes through its horizontal position.
- the means for controlling the adjustment of the additional boom include at least one angle sensor.
- the means for controlling the adjustment of the additional boom include at least one displacement sensor.
- the additional boom for extending the loading shovel can also be adjusted in a substantially horizontal direction below the horizontal position of the extension arm, the extension arm being switchable to a so-called floating position to compensate for the circular path of the loading shovel caused by the adjustment of the additional boom.
- This measure allows, for example, the special boom to be moved forward in special steering situations in which the shovel loader cannot be moved closer to the location of the pick-up or delivery of goods to be moved.
- the additional cantilever Before the cantilever arm can be raised from this position, the additional cantilever must be fully retracted to ensure that it does not tip over.
- an electrical angle or displacement sensor is advantageously provided for releasing the lifting movement by the cantilever arm.
- the length of the first link and the second link is essentially the same.
- the length of the first link is less than or greater than the length of the second link.
- This unequal configuration of the lengths of the first link and second link allows the end position of the additional boom to be influenced in the fully unfolded position.
- the first drivers i.e. the chassis remote from the boom arm
- the additional boom has a relatively flat positioning in relation to the fully raised boom.
- Figure 1 shows a shovel loader according to the invention in a side view with the boom fully retracted and fully extended.
- Figure 2 shows an enlarged view of the front section of the shovel loader of Figure 1 with the boom in an approximately horizontal position.
- FIG. 3 shows in an enlarged detail from FIG. 1 the front section of the shovel loader according to the invention with the boom fully folded in and fully extended.
- FIGS. 4a to 4c show the horizontal adjustment of the arm of the shovel loader according to the invention from FIG. 1 in a successive sequence, in which the loading shovel is moved forward along the floor.
- FIG. 5 shows the shovel loader according to the invention from FIG. 1 with a stacking fork as a working tool replacing the loading shovel in a horizontal adjustment of the boom along an elevated horizontal plane.
- FIG. 1 shows a shovel loader 1 according to the invention with articulated steering that can be driven on tires.
- the invention can also be implemented with other conventional shovel loaders with steering knuckle steering, crawler tracks and the like.
- a cantilever arm 3 is pivoted about a cantilever pivot axis 4 (cf. also FIG. 3).
- a first lifting cylinder 5, which serves to pivot the boom arm 3, engages at one end on the loader frame and at the other end approximately centrally on the boom arm 3.
- the components of the boom arm 3, boom pivot axis 4 and lifting cylinder 5 largely correspond to the standard parts of a standard shovel loader.
- the shovel loader 1 comprises an additional boom 7, the length of which in the exemplary embodiment shown and described is essentially somewhat shorter than the length of the boom arm 3.
- the additional boom 7 is articulated by means of a first link 8 and a second link 9 to the extension arm in the manner of a parallel link such that it comes to rest directly on the extension arm 3 in its folded position (see also FIG. 2).
- the links 8, 9 can each be individual links or, in particular, symmetrically arranged pairs of links.
- the first link 8 is articulated on an end of the boom arm 3 remote from the boom pivot axis 4 about an axis of rotation 6, which is the blade tilt axis of the series boom 3, while the link 9 engages approximately in the region of the center of the boom arm 3.
- the articulation axis 18 of the second link 9 on the extension arm 3 coincides with the articulation axis of the first lifting cylinder 5, which can of course be configured differently in other embodiments.
- the links 8, 9 are arranged on the additional boom 7, specifically in the area approximately in the middle of the additional boom 7 (link 8) and at an end 19 pointing towards the shovel loader 1 (link 9).
- a second lifting cylinder 15 is provided for moving the additional boom 7 out of and into its folded position on the boom arm 3, which is articulated at one end approximately centrally on the link 9 and at the other end on the boom arm 3 or on the boom pivot axis 4.
- other articulations of the second lifting cylinder 15 are also also the other actuating cylinders necessary to operate the entire boom and the loading shovel are possible.
- Both the first and the second lifting cylinder can be paired arrangements of hydraulic cylinders, if the size or the load to be handled by the loader so requires.
- the loading shovel 13 is actuated by means of a tilting linkage 11, 12 which has a rocker arm articulated (approximately in the middle) on the additional boom 7
- the tilt linkage 11, 12 is actuated by means of a tilt cylinder 14, which engages on one end on a central section of the rocker arm 12 and on the other end on the end 19 of the additional boom 7 facing the shovel loader 1.
- Loading shovel 13, tipping rods 11, 12 and tipping cylinder 14 can correspond to the normal series device and differ from the example shown.
- An angle sensor 16 or 17 is respectively arranged on the boom pivot axis 4 and on the bucket pivot axis 10.
- the angle sensors 16, 17 are used to determine the relative angle between the boom arm 3 and the vehicle body 2 or the position of the loading shovel 13 with respect to the additional boom 7.
- the hydraulic cylinders 14 are controlled electronically on the basis of the angle or position values determined by the angle sensors 16, 17 , 15.
- the angle sensor 16 is part of means for controlling the adjustment of the additional boom 7, as will be described below.
- other suitable sensors can of course also be used are used, for example displacement sensors, which are preferably arranged on the extension arm 3 or on the first lifting cylinder 5.
- the loading shovel 13 is lifted by pivoting the boom arm 3 about the boom pivot axis 4 by means of the first lifting cylinder 5.
- the axis of rotation 6 (bucket pivot point of the series device) describes a circular path Kl ( up to the highest position A) and the blade articulation axis 10 describes a circular path K2 which leads through a horizontal position D.
- the bucket pivot axis 10 is at the same height as the boom pivot axis 4 and the maximum radius corresponding to the minimum tipping load has been reached.
- the additional boom 7 initially remains unpowered in its retracted position on the boom arm 3, while the tilting cylinder 14 already actuates the loading shovel 13 in a controlled manner by the angle sensor 17 and associated control means, which are not shown in detail that the loading bucket 13 always points upwards with its opening (parallel holding function - cf. FIG. 2, in which the overall boom is shown in the position indicated by D in FIG. 3).
- an adjustment of the additional cantilever 7 begins by means of the second lifting cylinder 15, which is controlled by electronic control means connected to the angle sensor 16.
- the embodiment of the additional boom 7 is adjusted from a position Bl of the axis of rotation 6 of the boom 3, which is approximately 10 ° above the horizontal.
- an adjustment of the additional boom 7 can also begin in other positions, which, however, are preferably all above the maximum radius, in order to prevent the maximum radius from being exceeded even during loading work on slightly sloping terrain, or to ensure that it cannot tip over.
- the position B1 of the axis of rotation 6 corresponds to a position B2 of the bucket linkage axis 10, which represents the end point of the previous circular path K2 of the bucket linkage axis 10, since the bucket linkage axis 10 at the end of the additional boom 7 now moves more upward by actuation and the associated folding out of the additional boom 7 is considered on the circular path K2.
- the parallel holding function by hydraulically electronic adjustment of the angular position between the loading shovel and the additional boom 7 is thus superimposed on a folding-out movement of the additional boom 7, so that after reaching position A through the axis of rotation 6 of the extension arm 3, the bucket linkage axis 10 of the additional boom 7 has reached the highest position C.
- FIGS 4c The horizontal adjustment of the loading shovel below the horizontal position of the extension arm 3 is shown in FIGS 4c illustrates.
- FIG. 4 a shows the shovel loader according to the invention from FIG. 1 in the basic position with the boom lowered and the loading shovel 13 tilted out 13 is located. If, for example, this is not possible due to the unsuitable nature of the subsoil, the boom can now be moved forward according to the invention by actuating the additional boom 7, as shown in FIGS. 4b and 4c. For this purpose, the second lifting cylinder 15 is actuated and the links 8, 9 are adjusted.
- the cantilever arm 3 is switched to a so-called floating position, in which it is actuated by means of the first lifting cylinder 5 in such a way that the circular path of the loading shovel 13 caused by the adjustment of the additional boom 7 takes place, so that the loading shovel 13 essentially runs along a path horizontal plane, given by the ground.
- the loading shovel 13 is moved so far forward that it is sufficiently filled with the load L (FIG. 4c), the filled loading shovel is tipped over.
- the additional boom 7 must be completely retracted. This position corresponds to the position shown in Figure 4a, with the difference that the loading shovel 13 is tilted upwards. Only then can the cantilever arm 3 be raised, as explained above in connection with FIGS. 1 to 3.
- An electric angle or displacement sensor is preferably provided on the handlebar 9 or on the second lifting cylinder 15, which registers the position of the additional boom 7 and only when the additional extension is completely retracted. ger 7 releases the lifting movement for the cantilever arm 3. This ensures adequate tipping safety.
- FIG. 5 A corresponding application of the horizontal adjustment along a horizontal plane spaced from the floor is illustrated in FIG. 5 using the example of a stacker insert.
- the loading shovel 13 is replaced by a stacking fork 13 'as a working tool.
- the horizontal movement of the additional boom 7 according to the invention explained above with reference to FIGS. 4a to 4c can be used, as illustrated by the dash-dotted line, without the shovel loader having to be moved forwards or backwards.
- the particular advantage of the invention is based on the fact that the shovel loader according to the invention can be obtained with relatively simple means by exchanging the cantilever arm from a series shovel loader without the stability being significantly changed by an overly long cantilever arm and all the working tools of the series device can be used further.
- a small series shovel loader can be used for the upload work, the additional weight of the additional boom being compensated for by an additional counterweight (reference number 20 in FIG. 1).
- the circular paths Kl and K2 can coincide in the most favorable case. If, however, as in the exemplary embodiment shown, they are spaced apart from one another, this shift in the center of gravity must also be compensated by the additional counterweight 20.
- the invention is not limited to the exemplary embodiment shown in the figures, but also includes further structural modifications.
- the handlebar pairs 8 and 9 do not have to be of essentially the same length, as in the illustrated embodiment, but can also be of different lengths.
- the number of handlebars and their articulation points can be freely selected without departing from the scope of the invention.
- the cantilever arm 3 and / or the additional frame 7 can be equipped as desired, for example as a so-called mono-boom cantilever, as a hollow body box construction or as a frame formed from two side parts, as shown by way of example.
