Definitions
- the present invention relates to a quick coupling for coupling a Tool on a boom with a boom-side quick coupling part and a tool-side quick coupling part with a power circuit coupling, in particular hydraulic coupling, with plate-shaped carriers of the power coupling parts for automatically coupling a tool-side power connection to a cantilever-side power terminal, wherein in the plate-shaped carriers on the one hand male or female connector pieces as energy connections and spaced therefrom at least one guide pin or at least one Guide bore are integrated, which in the coupled state a perfect fit Ensure that the plate-shaped supports rest on one another, so that the plate-shaped Carrier to form a small gap largely parallel to each other are arranged.
- Swivel type quick couplings are widely used in hydraulic excavators since a simple and quick change of various tools such as hydraulic grippers, Gravenaum spoon, tongs and the like allowed.
- For coupling initially only needs one of the two locking axes positioned and engaged to be brought.
- This can advantageously be a transverse pin, which in a hook-shaped eyelet is hooked on the opposite coupling part.
- the latter is usually formed by a pair of locking bolts, the apart and in corresponding locking holes on the opposite Retract quick coupling part.
- the movable mounted energy coupling part the pivoting movement when moving together the quick coupling parts compensated by a linear guide and itself moved exactly so that between the two power coupling parts an exactly linear Movement takes place.
- the object of the invention is a generic construction machine with quick coupling in such a way that technical or safety risks safely prevented during automatic coupling of the tool to a construction machine become.
- this object is based on a generic Construction machine with the quick coupling by combining the features of Claim 1 solved. Accordingly, in or on one of the two plate-shaped carrier a read-write head and in the opposite plate-shaped carrier a disk arranged such that both together in the coupled state Can exchange data.
- the data carrier used according to the invention operates inductively.
- the read-write head only reliably exchanges data with this data carrier, if a small distance of, for example, about 3 - 5 mm is maintained exactly. This is ensured in the present system by the fact that the plate-shaped Carrier in the coupled state fit each other.
- the system can consist of read-write head on the one hand and data carrier On the other hand, they can also be used simultaneously as a security system, as here a data exchange can take place only if on the one hand the read-write head and on the other hand, the data carrier is in its desired position, So if the small distance of 3 - 5 mm is respected. That is only then the case when the locking bolt engages correctly and the system connects and the clutch closes. If the bolt accidentally does not close would, the distance would be so large that the read-write head with the disk just could not exchange data.
- the tool recognition means consisting of read-write head and data carrier, which are designed, for example, as an inductive system, are made possible.
- At least one of the two plate-shaped carrier part of an elastic Compensation system is provided.
- Such a compensation system allows a minimal gap spacing, so here the desired position for the Read-write head on the one hand and the disk on the other defined ingestible is.
- the type of the corresponding compensation system is already in the DE 101 59 417 C2, which is incorporated herein by reference.
- the compensation system by means of compression springs on which the respective plate-shaped Carrier support.
- the spring suspension is always ensures the optimal alignment of the plate-shaped carrier to each other.
- the Read-write head as well as the disk can be inside the plate-shaped Carrier be arranged. According to a particular embodiment of the invention but the read-write head as well as the data carrier but also on attachments, which connect to the plate-shaped carriers, be arranged.
- the complete records that are stored on the disk can be used are also operating data, such as data on the service life of the tool, contain.
- data on the service life of the tool contain.
- Such data are particular for various applications Interest. For example, when used as a rental tool by Landlord made an accurate billing after the appropriate use become. It can also be determined data, which tool as long on which excavator was used.
- the excavator can use the different data for each Tools are recorded so that here a total load of the excavator can be calculated is. Via a corresponding data interface, data of the tool also be read out via an interface on the excavator to the outside, so that you can query them centrally at a monitoring station.
- the automatic tool recognition allows with appropriate coupling the tool on the excavator the issue of a warning when the tool itself for the particular excavator or the work to be performed is not suitable.
- the identification of the tool also makes it possible to protect the excavator by:
- a tool with wrong Hydraulic oil is coupled.
- the tool indicates a maximum surcharge that must not be exceeded. This can for example, to a uniform, optimal compression with, for example an attached vibrating plate, a mounted roller compactor or the like to lead.
- the controlled introduction of a maximum force can also when using a appropriate construction machine, such as an excavator, for handling make materials safer. For example, by a Force limit of an excavator grab the bottom of a ship's hull protected become.
- the quick coupling 1 shown in the figures has a boom-side quick coupling part 2, pivotally on the stem 3 of a boom of a hydraulic excavator is attached and a non-illustrated pivoting pocket in itself known manner about the vertical axis to the longitudinal axis 3 of the pivot axis. 4 can be pivoted.
- the quick coupling 1 also has a tool side Quick coupling part 5, which is connected to a hydraulic excavator tool. This can be z. B. be a gripping tool with a rotating mechanism 6, the hydraulic is operable.
- the two parts 2 and 5 of the quick coupling 1 are connected to each other via two parallel, spaced apart locking axes 7 and 8 locked together.
- the locking axes 7 and 8 extend, as shown in Fig. 1, in parallel to the pivot axis 4, about which the quick coupling 1 is pivoted relative to the stem 3 can be.
- the locking bolt 8 is in an extended view shown. It can be hydraulically engaged and retracted.
- the first of the two locking axes 7 is on the one hand by a tool on the side Quick coupling part 5 provided transverse pin 9 and a pair on the boom-side quick coupling part 2 provided locking hook 10th educated.
- the locking hooks 10 can be hooked on the transverse bolt 9, so that it is gripped by the locking hooks 10 and the tool side Quick coupling part 5 can be raised (see Fig. 6).
- the locking hooks 10 are open to one side, hook-shaped recesses which surround the transverse pin 9 in the form of a half shell.
- the Hakenauslangisme are to the side of the quick coupling part. 2 open, which faces away from the second locking axis 8.
- the second locking axis 8 is on the one hand by a diverging Locking bolt pair 11 and an associated pair of locking holes 12 formed.
- the locking pin pair 11 on the jib-side quick coupling part 2 arranged and can by a per se known drive mechanism, preferably hydraulically retracted and extended become.
- the locking holes 12 are in the tool-side quick coupling part 5 formed.
- both have the boom side Quick coupling part 2 and the tool-side quick coupling part 5 spaced apart, substantially vertical support pieces, which from each other are spaced differently, so that the plate-shaped carrier of the jib-side quick coupling part between the plate-shaped carrier of the can retract tool side quick coupling part 5.
- the two Quick coupling parts 2 and 5 are pivoted together so far that the Locking bolt pair 11 and the associated locking holes 12 with each other aligned. Then, the locking bolts 11 are preferably through hydraulic loading apart, allowing them into the locking holes 12 retract. By the two locking axes 7 and 8 are the two quick coupling parts 2 and 5 firmly locked together.
- the two quick coupling parts 2 and 5 may be provided with a pivoting guide 44 (see Fig. 6).
- a hydraulic clutch 13 associated with a boom side hydraulic circuit with a tool-side hydraulic circuit connects z.
- B. can the Turning mechanism 1 shown in FIG. 1 are operated hydraulically. There can be more Drive elements and accordingly provided several hydraulic circuits and be coupled.
- the hydraulic clutch 13 comprises two power coupling parts 14 and 15, on the one hand on the boom-side quick coupling part 2 and on the other hand on the Tool-side quick coupling part 5 are mounted.
- the power coupling parts 14 and 15 are on the first locking axis 7 and 8 opposite sides arranged the quick coupling parts 2 and 5, in each case at the same distance from the first locking shaft 7, so that when pivoting together the two quick coupling parts 5 drive each other.
- the power coupling parts 14 and 15 outside the locking shafts 7 and 8, these are less prone and better to wait.
- the power coupling parts 14 and 15 respectively between the vertical support pieces 16 of the boom side Quick coupling part 2 and the vertical support pieces 17 of the tool side Quick coupling parts 5 arranged. They are protected by this. Especially Do not over the quick coupling parts 2 and 5 so over that the power coupling parts 14 and 15 would be pressed into the ground, if the corresponding quick coupling parts 2 are placed on the ground.
- Both power coupling parts 14 and 15 hold a plurality of power clutches together. They are each designed as a connector block in which a plurality of connector pieces 18 are summarized.
- this is on the boom side Quick coupling part 2 arranged energy coupling part 14 with its plate-like Carrier firmly stored, d. H. it is rigid relative to the quick coupling part 2.
- the attached to the tool-side quick coupling part power coupling part 15 with its plate-shaped support is movably mounted on this.
- the entire power coupling part 15 sits on a spring assembly 21, which in the embodiment shown in FIG. 4 arranged in a rectangular compression springs consists.
- the compression springs 22 are on the one hand attached to angle plates in the vertical support pieces of the tool-side quick coupling part 5 is arranged are.
- the springs 22 have a sufficient height and elasticity, so that the power coupling part 15 can be multiaxially displaced or tilted.
- the spring arrangement 21 forms a multi-axially movable mounting for the power coupling part 15, so this one offset to the opposite Energy coupling part 14, in particular due to the pivoting movement of the Quick coupling parts 2 and 5 can compensate.
- the linear guide 23 consists in the drawn Embodiment of a pair of guide pins 24 and associated guide holes 25 (see Fig. 3), the said guide pin 24 when moving together retract the two power coupling parts 14 and 15. They force it the springs 22 to a deflection to the pivoting movement component to compensate. In addition, offset due to tolerances in the Assembly also compensated (see Fig. 3 and 4).
- a read-write head 30 and in the plate-shaped Carrier 20 of the power coupling part 15 a data carrier 32 is arranged.
- the read-write head 30 and disk 32 must be in the coupled state, such as it is shown in Fig. 4, only a minimum distance of a few millimeters have from each other to transfer the data (inductive system). by virtue of however, the aforementioned locking mechanism ensures that that the energy coupling parts 14 and 15 come to lie exactly opposite each other. This ensures that the read-write head 30 on the one hand and the disk 32 arranged on the other hand in the exactly aligned position to each other are.
- the plate-shaped carrier 20 in section and in perspective view shown.
- the data carrier 32 in the plate-shaped carrier 20th used.
- the disk 32 before insertion into the corresponding receiving opening 31 of the plate-shaped Carrier 20 is shown.
- the data carrier 32 can in the opening, for example be glued.
- Fig. 1 the quick coupling is shown in not yet coupled state.
- the corresponding locking pin 11 but already extended, so that a correct coupling by retracting the locking pin 11 in the corresponding locking holes 12 are no longer possible.
- the read-write head 30 and the disk 32 can not communicate with each other communicate because they are too far apart. This will therefore simultaneously a fuse to the effect given that the quick coupling not is properly coupled.
