Description

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

In the prior art, arrangements of a crane base and a tool holder are known. A crane base of such an arrangement can be used to mount a crane on a carrier vehicle. In some cases, a tool arranged on the crane arm can be transported in the loading space together with any cargo. In many cases, especially with loose cargo, it may be necessary for cargo stored in the hold to be covered for transport, which means that it is not possible to place the tool in the hold. It is also sometimes 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 stored in a tool holder that is separate from the actual loading space. The crane can be in a retracted and possibly collapsed 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 stored or to be deposited in the tool holder, the crane arm of the crane must be brought into a specific position that is difficult to reach for reasons of space. This is associated with a high expenditure 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 provide an arrangement comprising 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 uncoupling of a tool that is deposited or to be deposited in a tool holder is intended to be simplified.

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

Advantageous embodiments of the invention are given 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 mounting a crane column of a crane arm of a crane. In the assembled position of the crane base, the crane pillar - and thus its crane arm when the crane is installed - can be mounted pivotably 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 or is arranged on a crane arm of the crane.

In principle, a tool can 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 can be earth drills, mulchers, Pallet forks, saws, grippers, digging grabs, bulk material grabs, rail grabs or wood grabs can be called.

The tool holder can in principle serve to store the tool in the uncoupled state, detached from a crane arm. The arrangement can thus, for example, enable a tool to be transported 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 designed 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 moving 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, the tool holder being movable 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 uncoupling 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 ruled out that the tool holder is moved by the movement device into any intermediate position between the at least one transport position and the at least one coupling position is movable, it being possible for there to be more than one transport position and / or more than one coupling position.

Due to the movement device, part of the movement of a crane arm required for coupling and / or uncoupling the tool on the crane arm due to a relative movement between the crane base and the tool holder or a corresponding offset between the crane base and the tool holder caused by the relative movement can be dispensed with. In other words, because the tool holder can be positioned between at least two positions relative to the crane base, the crane arm can more easily be brought into a position suitable for coupling and / or uncoupling the tool on the crane arm.

A tool stored in the tool holder can be moved together with the tool holder by means of 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 coupling and / or uncoupling of a tool to the crane arm is also possible here. However, due to certain circumstances, such as the relative position between the crane base and the tool holder, this can be much 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 coupling and / or uncoupling of a tool in the transport position of the tool holder is not possible 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 uncoupling 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 have 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 approximated 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 be measured essentially transversely to an axis specified by the crane base. In particular, the axis specified by the crane base can be an axis running vertically in the assembly position of the crane base 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 in a position approaching the crane base can be very difficult or impossible to reach. With such a positioning of the tool holder, actuators, bending angles between individual arms of the arm system and extension lengths of individual extensions of the arm system can be located in the limit area of the respective possible freedom of movement. This can make precise positioning of a crane arm difficult.

If the tool holder is in a position 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 connecting and / or disconnecting one Tool in the coupling position of the tool holder required position of the crane arm 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 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 boom with a drive or an energy store and move the tool holder between at least one transport position and at least one coupling position by moving the boom relative to the crane base.

It can be advantageous if the movement device comprises a telescoping device and the boom can be telescopically extended 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 are also conceivable, such as telescoping devices provided specifically for the mobility of the tool holder.

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

By pivoting the boom, the distance between the tool holder and the crane base of the crane base can be changed. 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. A raised stand can in principle provide a secured operating area with good visibility into the work area for a user. A common design of the raised stand with the tool holder has the advantages that the space required for the raised stand on the arrangement can serve 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 raised stand is designed as a raised seat.

In an advantageous embodiment, the tool holder has holding elements for the form-fitting and / or force-fitting fastening of a tool. The holding elements can be designed as projections and / or recesses which encompass which parts of a tool and / or which parts of a tool can engage.

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

A vehicle can have a longitudinal extension (vehicle length) along a longitudinal axis, a transverse extension (vehicle width) along a transverse axis and a vertical extension (vehicle height) along a height 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 screwed to the vehicle frame.

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

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

In the assembly 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, the latter can be in a position approaching the crane base of the crane base in the direction transverse to the longitudinal axis of the vehicle. In the at least one coupling position of the tool holder of the arrangement, the latter can be in a position that is further away from the at least one transport position in the direction transverse to the longitudinal axis of the vehicle relative to the crane base.

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 as a result of the movement device.

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

Protection for a crane with an arrangement as described above is also desired.

Such a crane can include a crane base with a crane base for mounting a pivotably mounted crane column of a crane arm of the crane, at least one tool holder for receiving a tool that can be or is arranged on the crane arm 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.
• Remove the coupled tool from the tool holder.

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

Protection is also sought for a method for uncoupling 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 folded 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 folded arm position and the tool holder 7 is in a coupling position.

In the front and side views of the Figures 3a and 3b is the crane arm 9 in a for coupling and uncoupling of a tool 8 in

Tool holder 7 suitable arm position and the tool holder 7 is in a coupling position.

In the illustrated first embodiment of the arrangement 1, this 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 mounting a pivotably mounted crane column 6 of the crane 3. In the illustrated assembly position of the crane base 2, 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 as a gripper, for example.

The tool 8 is shown in the Figures 1a and 1b stored in the tool holder 7. The tool holder 7 is in a transport position approximated to 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 uncoupling a tool 8 on 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, the tool holder 7 being arranged at the outer end of the boom 11. In the embodiment shown, the movement device 10 is formed by a telescopic device 14, specifically a telescopic support widening with a support leg 14, through which the boom 11 - and thus the tool holder 7 together with the tool 8 - can be telescopically extended relative to the crane base 2.

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

In the representation of the Figure 2 the tool holder 7 is in a coupling position remote from the crane base 5. 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 approximated 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 from the transport position at a distance d2.

When the booms 11, 12 move, in the embodiment shown, the linear telescopic movement maintains an alignment of the tool holder 7 relative to the crane base 5 of the crane base 2. In contrast 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 the 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 in relation to its position in the preceding figures.

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

In the first embodiment of the arrangement 1, the movement 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 is 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 performed by a sequence of Figures 1a , 2 and 3a to be illustrated.

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

In a second method 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 Figure 2 to the Figure 3a correspond.

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

In the reverse sequence, a method for uncoupling 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 optionally be moved from a transport position to a coupling position by the movement device 10, whereupon the crane arm 9 is positioned in an arm position of the crane arm 9 suitable for inserting the tool 8 into the tool holder 7 (see, for example, FIG 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 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 on the rear of the vehicle frame 22 of the vehicle 4.

Figure 5 FIG. 11 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 height axis z.

In the assembly position of the crane base 2 on the vehicle 4, a distance d1, d2 of the tool holder 7 from the tool holder 7 is in this embodiment due to the movement device 10 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 movement device 10 of the Figures 8 and 9 A distance between the tool holder can also be changed in the direction of the vertical axis z.

The vehicle 4 has a vehicle width w along a transverse axis y. The tool holder 7 can be located essentially completely within the vehicle width w in at least one possible transport position (distance d1, schematic representation of the tool holder 7 with a solid line). 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 located 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 that is similar to the embodiment described above is shown, which additionally has a raised stand 18 for a user, the raised stand 18 and the tool holder 7 being designed as a common structural unit. In the Figures 6a and 6b a use of the tool holder 7 for storing a tool 8 is shown and in FIG Figures 7a and 7b a use of the raised stand 18 by a user is shown.

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 which 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, it should not be ruled out that the arms 15, 16 are designed to be variable in length.

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

In contrast 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 boom.

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

The tool 8 is shown in the Figure 8 stored in the tool holder 7. The tool holder 7 is in a transport position approximated to 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 the Figure 9 the tool holder 7 is in a coupling position remote from the crane base 5. 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 approximated 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 from the transport position at a distance d2.

Due to the parallelogram guidance of the booms 15, 16, when the booms 15, 16 move, an alignment of the at least one tool holder 7 relative to the crane base 5 of the crane base 2 can be maintained. In contrast to what is shown, however, provision can also be made for the orientation of the tool holder 7 to change relative to the crane base 5 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 approximated to crane base 5 at distance d1), it should not be ruled out that a tool 8 can also be coupled and / or uncoupled from the crane arm here . As can be seen from the illustration, this can be much more difficult due to the relative position between the crane base 2 and the tool holder 7. The articulation angle positions of the individual arms of the crane arm 9, which is designed as an articulated arm, can be located in the limit areas of the mobility of the joints of the crane arm 9 when coupling and / or uncoupling 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 resulting change in position, reaching and leaving such a position can be difficult. Also, when the tool 8 is removed from or deposited in a transport position, the risk of damage to the crane 3 or a carrier vehicle is increased.
