Description

The invention relates to an arrangement of a crane base and a tool holder according to the preamble of claim 1.

Arrangements consisting of a crane base and a tool holder are known in the prior art. A crane base of such an arrangement is in EP3401269 described and can be used to mount a crane on a carrier vehicle. In some cases, a tool arranged on the crane arm of the crane can be transported in the hold together with any cargo. In many cases, especially with loose cargo, it may be necessary for cargo placed in the cargo hold to be covered for transport, making it impossible to place the tool in the cargo hold. In some cases it is also not possible to leave the tool on the crane arm during transport. In such or other cases, a tool that can be operated with the crane, such as a gripper, can be placed in a tool holder that is separate from the actual loading space. The crane can be in a retracted and optionally folded state. Conversely, the crane can pick up a tool placed on the tool holder for crane operation.

To transport the crane with the carrier vehicle, the crane and the tool holder must be arranged within a permissible width of the carrier vehicle. For reasons of space, the tool holder is often designed directly on the crane base. In order to couple or uncouple a tool placed or to be placed in the tool holder, the crane arm of the crane must be brought into a specific position which is difficult to reach for reasons of space. This is associated with a great deal of time, high demands on the user of the crane and a high risk of damage to the crane or the carrier vehicle.

The object of the invention is to specify an arrangement made up of a crane base and a tool holder, as well as a crane and a vehicle with such an arrangement, in which the problems discussed above do not occur. In particular, coupling or decoupling of a tool placed or to be placed in a tool holder should be simplified.

This object is achieved by an arrangement according to the characterizing part of claim 1, and by a crane and a vehicle with such an arrangement and method for coupling and decoupling a tool.

Advantageous embodiments of the invention are specified in the dependent claims.

The arrangement initially comprises a crane base for mounting a crane on a vehicle, the crane base having a crane base for supporting a crane column of a crane arm of a crane. In the assembled position of the crane base, the crane column—and thus its crane arm when the crane is assembled—can be pivoted about an upright and essentially vertical pivot axis.

To mount the crane on a vehicle, the crane base can be arranged, for example, on or on a vehicle frame and screwed directly or indirectly to it.

The arrangement further comprises at least one tool holder for receiving a tool that can be arranged or is arranged on a crane arm of the crane.

A tool can basically be understood as a device by means of which cargo can be manipulated with the crane or work can be carried out with the crane. Examples include augers, mulchers, Pallet forks, saws, grabs, grabs for digging, grabs for bulk goods, grabs for rails or grabs for wood are mentioned.

In principle, the tool holder can be used to store the tool when it is uncoupled and detached from a crane arm. The arrangement makes it possible, for example, to transport a tool safely with a vehicle. A tool placed on the tool holder can be coupled to the crane for crane operation.

The tool holder can be formed separately from the crane base.

In general, it can be provided that a tool arranged on the crane arm can be placed in the tool holder by movements of the crane arm and, if necessary, by actuating a coupling device. A tool stored in the tool holder can be arranged on the crane arm by moving the crane arm and, if necessary, by actuating a coupling device.

The arrangement further comprises at least one movement device, wherein the tool holder can be moved by the at least one movement device between at least one transport position for transporting a tool and at least one coupling position for coupling and/or decoupling a tool to a crane arm.

A relative movement between the crane base and the tool holder can be made possible by the movement device. As a result, the tool holder can be moved at least between two positions relative to the crane base.

It should not be excluded that the tool holder by the movement device in any intermediate position between the at least one transport position and the at least one coupling position is movable, whereby there can be more than one transport position and/or more than one coupling position.

The movement device makes it possible to eliminate part of the movement of a crane arm required for coupling and/or decoupling the tool to the crane arm by a relative movement between the crane base and the tool holder or by a corresponding offset between the crane base and the tool holder caused by the relative movement. In other words, due to the positionability of the tool holder between at least two positions relative to the crane base, the crane arm can be brought more easily into a position suitable for coupling and/or decoupling the tool on the crane arm.

A tool placed in the tool holder can be moved together with the tool holder by the movement device.

The transport position of the tool holder can be particularly suitable for transporting a tool. For the transport position, it should not be ruled out that a tool can also be coupled and/or uncoupled to the crane arm here. However, due to certain circumstances, such as the relative position between the crane base and the tool holder, this can be significantly more difficult than, for example, in the coupling position, so that the advantages of the invention may not be able to be used. It is also conceivable that a tool cannot be coupled and/or uncoupled in the transport position of the tool holder because, for example, a coupling point of the tool is not accessible or a crane arm cannot be brought into a position in which the tool can be reached can.

The coupling position is characterized in that it is particularly suitable for coupling and/or decoupling a tool to the crane arm of a crane.

The tool holder can be at a first distance from the crane base in the transport position. In the coupling position, the tool holder can be at a second distance from the crane base. In an advantageous embodiment, the second distance can be greater than the first distance.

In an advantageous embodiment, the tool holder can be in the at least one transport position in a position closer to the crane base, and the tool holder in the at least one coupling position can be in a position further away from the crane base compared to the transport position.

The distance between the tool holder and the crane base of the crane base can essentially be measured transversely to an axis defined by the crane base. In particular, the axis specified by the crane base can be an axis that runs vertically when the crane base is in the installed position, and the distance between the tool holder and the crane base can be measured in the horizontal direction.

In the event that a tool is to be coupled from a tool holder or uncoupled into a tool holder, in particular to or from a crane tip of a crane arm, a tool holder located in a position close to the crane base can be reached only with great difficulty or not at all. When the tool holder is positioned in this way, actuators, bending angles between individual arms of the arm system and extension lengths of individual extensions of the arm system can be in the limit range of the respectively possible freedom of movement. This can make it difficult to position a crane arm precisely.

If the tool holder is in a position that is further away from the crane base compared to the transport position, that is to say at a greater distance from the crane base, a crane arm of a crane can be positioned much more easily. One for coupling and/or decoupling a The position of the crane arm required for the tool in the coupling position of the tool holder can essentially correspond to an easily accessible, normal working position of the crane arm.

In an advantageous embodiment, the movement device is formed on the crane base or is connected to it. The movement device can be formed directly on the crane base or integrated into it, or connected to it, for example via a common screw connection on a vehicle frame.

In a particularly advantageous embodiment, the movement device can have at least one boom that can be moved relative to the crane base, and the tool holder can be arranged on the at least one boom. The movement device can act on the jib with a drive or an energy accumulator and move the tool holder between at least one transport position and at least one coupling position by moving the jib relative to the crane base.

It can be advantageous if the movement device includes a telescoping device and the jib can be extended telescopically relative to the crane base.

The movement device can have a hydraulic or electric drive.

The telescoping device can preferably be part of a telescopic support extension of the arrangement. Other designs, such as telescoping devices provided specifically for the mobility of the tool holder, are also conceivable.

Alternatively or in combination with this, it can be advantageous if the movement device has a pivoting device for the at least one boom and the boom can be pivoted relative to the crane base.

A distance between the tool holder and the crane base of the crane base can be changed by pivoting the boom. The boom can preferably be pivotable about a pivot axis running transversely to the pivot axis of the crane column.

In an advantageous embodiment, the arrangement can have a raised stand for a user and the raised stand and the at least one tool holder can be designed as a common structural unit. In principle, a raised stand can provide a secure operating area with a good view of the work area for a user. A joint design of the raised stand with the tool holder has the advantages that the space required for the raised stand on the arrangement can be used as storage space for a tool when not in use, and also that the raised stand can be moved relative to the crane base of the crane base by the movement device. It should not be ruled out that the high stand is designed as a high seat.

In an advantageous embodiment, the tool holder has holding elements for the positive and/or non-positive attachment of a tool. The holding elements can be designed as projections and/or recesses, which can encompass parts of a tool and/or into which parts of a tool can engage.

As already mentioned at the outset, protection is also sought for a vehicle with an arrangement as described above.

A vehicle may have a longitudinal extent (vehicle length) along a longitudinal axis, a transverse extent (vehicle width) along a transverse axis, and a vertical extent (vehicle height) along a vertical axis.

A crane base of an arrangement can, for example, be arranged directly or indirectly on or on a vehicle frame of the vehicle. For example, the crane base can be bolted to the vehicle frame.

In an advantageous embodiment, the movement device of the arrangement can be formed on the crane base and can thus be arranged together with it on the vehicle frame.

In a further embodiment, the movement device of the arrangement can be designed separately from the crane base and, for example, can be arranged separately from this on the vehicle, in particular on the vehicle frame.

In the installed position of the crane base on the vehicle, a distance between the tool holder and the crane base can advantageously be changed at least transversely to the longitudinal axis of the vehicle, and preferably in the direction of the transverse axis, by means of the movement device. Thus, in the at least one transport position of the tool holder of the arrangement, it can be in a position that is closer to the crane base of the crane base in a direction transverse to the longitudinal axis of the vehicle. In the at least one coupling position of the tool holder of the arrangement, this can be located in a direction transverse to the longitudinal axis of the vehicle relative to the crane base in a position further away than the at least one transport position.

It should not be ruled out that the tool holder can also be moved in a direction other than in the direction of the transverse axis of the vehicle by the movement device.

In an advantageous embodiment, in the at least one transport position, the tool holder can be located essentially completely within the transverse extent or width of the vehicle. In the at least one coupling position, the tool holder can be located in a position further away from the crane base and partially outside the width of the vehicle. Preferably, the tool holder can be substantially are completely outside the width of the vehicle. A vehicle width can be given by the transverse stretching of the body and/or the wheels (or similar drive means such as a caterpillar drive).

Protection is also sought for a crane having an arrangement as previously described.

Such a crane can include a crane base with a crane base for supporting a pivoted crane column of a crane arm of the crane, at least one tool holder for receiving a tool that can be arranged or is arranged on the crane arm of the crane and at least one movement device for the tool holder.

In an advantageous embodiment of the crane, it can be a knuckle-boom crane.

In an advantageous embodiment of a vehicle as described above, it can have a crane.

Protection is also sought for a method for coupling a tool to a crane arm of a crane with an arrangement as described above.

• Positioning the crane arm in an arm position suitable for coupling the tool from the tool holder.
• Coupling the tool from the tool holder.
• Removing the coupled tool from the tool holder.

If the movement device is formed by a telescopic support extension of the crane, the tool holder can be moved with the tool from a transport position into a coupling position when the crane is set up for work.

Protection is also sought for a method for decoupling a tool from a crane arm of a crane with an arrangement as described above

Figure 1a, 1b , 2 , 3a, 3b and 3c show views of a first embodiment of a crane 3 with a first embodiment of an arrangement 1. In the embodiment shown, the crane 3 is designed as a knuckle-boom crane.

In the front and side views of the Figures 1a and 1b the crane arm 9 is in a collapsed arm position and the tool holder 7 is in a transport position.

In the front view of the figure 2 the crane arm 9 is in a collapsed arm position and the tool holder 7 is in a coupled position.

In the front and side views of the Figures 3a and 3b is the crane arm 9 in a for coupling and decoupling of a tool 8 in Tool holder 7 suitable arm position and the tool holder 7 is in a coupled position.

In the first embodiment of the arrangement 1 shown, it comprises a crane base 2 for mounting a crane 3 on a vehicle 4 (see, for example, Figures 4a, 4b , 5 , 8th and 9 ) with a crane base 5 for supporting a pivotably mounted crane column 6 of the crane 3. In the assembly position of the crane base 2 shown, the pivot axis s1 runs essentially vertically. In this embodiment, the arrangement 1 further comprises a tool holder 7 for receiving a tool 8 which can be arranged on a crane arm 9 of the crane 3 and which is designed here, for example, as a gripper.

The tool 8 is in the representation of Figures 1a and 1b stored in the tool holder 7. The tool holder 7 is in a transport position approaching the crane base 5 . In the transport position shown, the tool holder 7 is at a first distance d1 from the crane base 5 .

The arrangement 1 further comprises a movement device 10 with which the tool holder 7 can be moved between at least one transport position for transporting a tool 8 and at least one coupling position for coupling and/or decoupling a tool 8 to the crane arm 9 .

In the embodiment shown, the movement device 10 has two booms 11 , 12 that can be moved relative to the crane base 2 , with the tool holder 7 being arranged at the outer end of the boom 11 . The movement device 10 is formed in the embodiment shown by a telescopic device 14, specifically a telescopic support extension with a support leg 14, through which boom 11 - and thus the tool holder 7 including tool 8 - relative to the crane base 2 is telescopically extendable.

The movement device 10 can have a hydraulic or electric drive, not shown here.

In the representation of figure 2 is the tool holder 7 in a remote from the crane base 5 coupling position. In the coupling position shown, the tool holder 7 is at a second distance d2 from the crane base 5 . A comparison with the Figure 1a shows that the second distance d2 is greater than the first distance d1.

In the at least one transport position, the tool holder 7 is in a position closer to the crane base 5 at a distance d1, and in the at least one coupling position the tool holder 7 is in a position further away than the transport position at a distance d2.

When the booms 11, 12 move, in the illustrated embodiment, the linear telescoping movement maintains an alignment of the tool holder 7 relative to the crane base 5 of the crane base 2. Contrary to what is shown, it can be provided that an alignment of the tool holder 7 relative to the crane base 5 changes when the tool holder 7 moves.

In the representations of Figures 3a and 3b the tool 8 in the tool holder 7 is coupled to the crane arm 9 via a tool changer 22 arranged on the crane tip 21 of a telescopic boom 20 of the crane arm 9 . The support leg 14 is folded down from its position in the previous figures.

In the embodiment shown, the tool holder 7 has holding elements 19 for the positive and/or non-positive attachment of a tool 8 . Rod-shaped holding elements 19 are used for a form-fitting attachment, while a bar-shaped holding means 19 that can be gripped by the tool 8 designed as a gripper can allow the tool 8 to be fastened in the tool holder 7 with a non-positive and form-fitting connection.

In the first embodiment of the arrangement 1 the moving device 10 is formed on the crane base 2 .

In Figure 3c the crane arm 9 of the crane 3 is shown in a position which results shortly after a coupled tool 8 has been removed from the tool holder 7 or shortly before a coupled tool 8 is deposited in the tool holder 7 . As shown, the tool holder 7 is in a coupling position remote from the crane base 5 .

A method for coupling a tool 8 to a crane arm 9 of a crane 3 with an arrangement 1 can be carried out by a sequence of Figures 1a , 2 and 3a be illustrated.

In a first method step, the movement device 10 moves the tool holder 7 with the tool 8 placed therein from a transport position into a coupling position. This can make the transition Figure 1a to the figure 2 correspond to.

In a second step, the crane arm 9 is positioned in an arm position of the crane arm 9 that is suitable for coupling the tool 8 from the tool holder 7. This can be the transition from the figure 2 to the Figure 3a correspond to.

In a third method step, the tool 8 is coupled out of the tool holder 7, after which the coupled tool 8 can be removed from the tool holder 7 (see, for example, Figure 3c ).

In the reverse sequence, a method for decoupling a tool 8 from a crane arm 9 of a crane 3 with an arrangement 1 can be illustrated

In a first method step, the tool holder 7 can be moved from a transport position into a coupling position by the movement device 10, whereupon the crane arm 9 can be positioned in an arm position of the crane arm 9 that is suitable for inserting the tool 8 into the tool holder 7 (see, for example, Figure 3c ) and the tool 8 can be inserted into the tool holder 7 . Such a configuration can be found, for example, in Figure 3a be seen.

After the tool 8 has been uncoupled from the crane arm 9 in the tool holder 7 , the tool holder 7 can be moved with the tool 8 from a coupling position into a transport position by the movement device 10 . Such a configuration can be found, for example, in figure 2 be seen.

Optionally, the crane arm 9 can then be moved into an arm position suitable for transport. Such a configuration can be found, for example, in Figure 1a be seen.

In the Figures 4a, 4b and 5 an embodiment of a vehicle 4 with an arrangement 1 according to the previously discussed first exemplary embodiment is shown.

In Figure 4a the crane 3 with the arrangement 1 is mounted on the vehicle frame 22 of the vehicle 4 behind the driver's cab. In Figure 4b the crane with the arrangement 1 is mounted at the rear on the vehicle frame 22 of the vehicle 4 .

figure 5 shows a schematic plan view of the vehicle of FIG Figure 4a .

The vehicle 4 has a longitudinal axis x, a transverse axis y and a vertical axis z.

In the installed position of the crane base 2 on the vehicle 4, in this embodiment the moving device 10 has a distance d1, d2 between the tool holder 7 and the Crane base 5 can be changed transversely to the longitudinal axis x of the vehicle 4 and in the direction of the transverse axis y. In the embodiment of the moving device 10 of figures 8 and 9 a distance of the tool holder can also be variable in the direction of the vertical axis z.

The vehicle 4 has a vehicle width w along a transverse axis y. In at least one possible transport position (distance d1, schematic representation of the tool holder 7 with a solid line), the tool holder 7 can be essentially completely within the vehicle width w. In at least one possible coupling position of the tool holder 7 (distance d2, schematic representation of the tool holder 7 with a dashed line), the tool holder 7 can be essentially completely outside the vehicle width w. An intermediate position, in which the tool holder 7 is partially outside the vehicle width w, is also conceivable.

In the Figures 6a, 6b and 7a , 7b an embodiment of an arrangement 1 similar to the embodiment described above is shown, which additionally has a high stand 18 for a user, the high stand 18 and the tool holder 7 being designed as a common structural unit. In the Figures 6a and 6b is shown a use of the tool holder 7 for storing a tool 8 and in the Figures 7a and 7b 1 is shown use of the high stand 18 by a user.

In the figures 8 and 9 a third embodiment of an arrangement 1 mounted on a vehicle frame 22 of a vehicle not shown here is shown.

In this embodiment, the movement device 10 is designed separately from the crane base 2 and is connected to it via the vehicle frame 22 .

In this embodiment, the movement device 10 has two booms 15 , 16 that can be moved relative to the crane base 2 . The tool holder 7 is arranged at an outer end of the arms 15,16.

As in figure 9 is indicated, should not be ruled out that the cantilevers 15, 16 are designed to be variable in length.

In the embodiment shown, the moving device 10 has a pivoting device 17 with parallelogram guidance for the booms 15, 16, the booms 15, 16 being pivotable relative to the crane base 2 about a pivot axis s2 running transversely to the pivot axis s1 of the crane column 6.

Contrary to what is shown, however, the provision of a parallelogram guide is not absolutely necessary. It should also not be ruled out that the pivoting device 17 only has a single pivotable extension arm.

The movement device 10 can have a hydraulic or electric drive, not shown here.

The tool 8 is in the representation of figure 8 stored in the tool holder 7. The tool holder 7 is in a transport position approaching the crane base 5 . In the transport position shown, the tool holder 7 is at a first distance d1 from the crane base 5 .

In the representation of figure 9 is the tool holder 7 in a remote from the crane base 5 coupling position. In the coupling position shown, the tool holder 7 is at a second distance d2 from the crane base 5 . A comparison with the figure 8 shows that the second distance d2 is greater than the first distance d1.

In the at least one transport position, the tool holder 7 is in a position closer to the crane base 5 at a distance d1, and in the at least one coupling position the tool holder 7 is in a position further away than the transport position at a distance d2.

Due to a parallelogram guidance of the outriggers 15, 16, an alignment of the at least one tool holder 7 relative to the crane base 5 of the crane base 2 can be maintained when the outriggers 15, 16 move. In contrast to what is shown, however, it can also be provided that the alignment of the tool holder 7 relative to the crane base 5 changes during a movement.

As in figure 10 is shown, for the transport position, i.e. while the tool holder is in a transport position (position closer to the crane base 5 at a distance d1), it should not be ruled out that a tool 8 can also be coupled and/or uncoupled to the crane arm here . As can be seen from the illustration, this can be significantly more difficult due to the relative position between the crane base 2 and the tool holder 7 . The articulated angle positions of the individual arms of the crane arm 9 designed as an articulated arm can be located in the limit areas of the mobility of the joints of the crane arm 9 when being coupled and/or uncoupled in a transport position. Since there is often a non-linear relationship between the movement of the drives of the crane arm 9 and the change in position caused thereby, reaching and leaving such a position can be difficult. The risk of damage to the crane 3 or a carrier vehicle is also increased when the tool 8 is removed or put down in a transport position.
