Description

[Technical Field]

[0001] The present invention relates to a mounting device for an excavator stick. [Background technology]

[0002] German Utility Model No. 202011100482 discloses an excavator that houses an attachment device at the free end of a stick. The attachment device is connected to a coupling device on the attachment device so that it can pivot about the attachment axis of the stick. A swivel drive is provided on the coupling device, which also has a coupling part on the opposite side of the coupling device for receiving an implement. The attachment device includes a rotation device with a rotation drive, whereby the coupling part can rotate about a rotation axis relative to the drive housing of the rotation device. Furthermore, another swivel drive is provided on the upper side of the drive housing, whereby the entire rotation device can pivot about an axis perpendicular to the rotation axis relative to the coupling device. The coupling device has a mounting bearing point and a coupling bearing point, both of which are located above the additional swivel drive. This results in a large overall height of the attachment device between the mounting bearing point of the coupling device and the coupling part, which impairs the pivoting movement of the attachment device relative to the stick.

[0003] [Patent Document 1] German Utility Model No. 202011100482 Summary of the Invention [Problem to be solved by the invention]

[0004] The invention is based on the problem of creating a mounting device for an excavator stick that allows control of a mounting with a larger swivel range. [Means for solving the problem]

[0005] This problem is solved by an attachment device in which a rotation plane is formed between the drive housing and the coupling part of the rotation device, and a virtual connection plane of the fixedly arranged coupling device is formed by an at least partially formed cover surface of the drive housing. Here, the attachment bearing point of the coupling device is located on the virtual connection plane of the at least partially formed cover surface of the drive housing, or on the rotation plane, or in the area between the connection plane and the rotation plane, and the coupling bearing point of the coupling device is located above the connection plane. This arrangement allows the rotation axis about which the attachment device can pivot on the stick to be lowered in the direction of the rotation plane of the attachment device. The rotation axis of the attachment device is located on the axis of the attachment point, whereby the attachment device is pivotally fixed to the attachment axis of the stick.

[0006] Preferably, the coupling device is mounted to the drive housing in a non-rotatable and / or non-pivotable manner, which allows for direct power transmission.

[0007] Furthermore, the coupling bearing point of the coupling device is preferably located in an upper region of the rotational feedthrough to the drive housing. This allows for the transmission of central forces through the pivot mechanism to the coupling bearing point. Additionally, this arrangement of the mounting and coupling bearing points can enable an improved leverage ratio and therefore increased power transmission to the instrument.

[0008] The coupling device is preferably removably provided at the virtual connection level or at the drive housing, Alternatively, the coupling device can be connected in one piece to the connection level of the drive housing.

[0009] Preferably, the coupling device has two side plates that are removably attached to the at least partially extended cover surface of the drive housing. These side plates can then be adapted depending on the design of the stick or stick end to achieve a large pivot range for the mounting device. Alternatively, the side plates of the coupling device can be integrally formed with the drive housing. This can allow for cost-saving manufacturing. In particular, this can result in weight savings.

[0010] Furthermore, preferably, at least two side plates of the coupling device are connected to each other by at least one connecting plate. This allows the side plates and the connecting plate to be removably connected to the rotation device as a single unit. In particular, at least one connecting plate is provided that can be connected to the rotation device by a screw connection. This provides adaptability in that the coupling device is provided exchangeably on the rotation device, thereby allowing application to different sticks by exchanging the coupling device.

[0011] The drive housing of the rotation device advantageously has at least one flat or flat surface between the at least partially formed cover surface and the end surface of the drive housing to which the mounting bearing point is assigned. This makes it possible to move the mounting bearing point closer to the drive housing. The distance between the rotation axis of the mounting bearing point in the coupling device and the rotation axis of the rotation device around which the coupling is rotatably mounted relative to the drive housing can be further reduced.

[0012] Furthermore, preferably, at least one flat is provided in the direction of the end face of the rotating device, inclined at an angle of 15 to 75° relative to the cover face. Preferably, only one flat is provided between the cover face and the end face of the rotating device. This flat may be inclined at an angle of 45° relative to the cover face. Alternatively, two or more inclined faces arranged side by side may be provided. These may be positioned side by side at the same or different angles.

[0013] In particular, the distance between the attachment point axis and the rotation axis of the rotation device is intended to be shortened by at least one inclined section. This makes it possible to create an improved force ratio. Additionally, at least one flat can also be used to reduce the shear force in the spring connection of the rotation device to the coupling device. This means that the thread cross section can be reduced.

[0014] According to another advantageous design of the attachment device, at least one connecting plate of the coupling device is provided to be connected to or rest on the flat portion and at least one other connecting plate of the coupling device is provided to be connected to the upper surface of the rotation device, which has the advantage that the shear forces occurring in the coupling device can be reduced.

[0015] Furthermore, the mounting bearing points of the coupling device are preferably allocated to the flat part or the end face of the rotating device, this allocation also depending on the positioning of the mounting bearing points between the connecting face and the rotating face, this allocation may also depend on the size of the inclination, since this can extend at least partially or completely from the cover face opposite the end face of the rotating device.

[0016] In another advantageous embodiment, the mounting bearing point and the bearing point of the coupling device are arranged at an angle β relative to the mounting device, and this angle β is formed by two imaginary straight lines. One or one imaginary straight line extends through the mounting bearing point and the coupling bearing point, and the second or other imaginary straight line extends in the plane of rotation of the rotation device or parallel to the plane of rotation of the rotation device, and is offset from the direction of the cover surface. This offset arrangement of the coupling bearing point and the mounting bearing point on the coupling device allows the mounting bearing point to be offset in the direction of the plane of rotation of the rotation device. This allows the setting height of the mounting device relative to the stick to be reduced. In particular, this increases the pivot angle range of the mounting device relative to the underside of the stick.

[0017] Advantageously, the imaginary straight line of the attachment device is provided at an angle β of between 15 and 45°, preferably between 25 and 35°, which in turn enables advantageous connection of the attachment device to both the straight and cranked stick portions of the stick.

[0018] Furthermore, a rotary feedthrough is preferably provided in the drive housing. The rotary feedthrough has a stator fixed to the drive housing so as not to rotate and a rotor that can rotate relative to the stator. The rotary feedthrough is connected to the coupling and to at least one connection, preferably three, in the coupling. This allows for a compact design of the mounting device. Additionally, internal supply and discharge of drive fluid from and to the tool or to the coupling can be enabled. Advantageously, one connection is provided as a supply line for supplying the working fluid. Another connection is connected to a supply line for discharging the working fluid, and a third connection can be provided for leakage fluid.

[0019] The invention as well as other advantageous and alternative embodiments thereof are described and explained in more detail below with reference to examples shown in the drawings. The features from the description and drawings can be used individually or in any combination according to the invention. [Brief explanation of the drawings]

[Figure 16] FIG. 2 is a schematic side view of an excavator with an alternative work tool to that of FIG. 1; DETAILED DESCRIPTION OF THE INVENTION

[0021] FIG. 1 shows a schematic side view of an excavator 11. The excavator 11 comprises a basic machine 13 with a boom 12, which is hinged at its end with a stick 14. The boom 12 is moved up and down by a lifting cylinder 19. The boom 12 comprises at least one stick cylinder 18 for actuating the pivotal movement of the stick 14. At least one pressure cylinder 16 is provided on the stick 14, thereby actuating an attachment device 21 provided on the stick 14. The attachment device 21 is pivotally attached to the end of the stick 14 at an attachment axis 17. This attachment device 21 may comprise a rotation device 22 with a rotation drive 24 and a coupling part 23, which may in particular be a quick-change coupling. The rotation device 22 comprises a drive housing 66. The rotation drive 24 enables the coupling part to rotate along the rotation axis 26 relative to the drive housing 66. A work tool 25 is exchangeably attached to the coupling part 23. A pivoting mechanism 27 is provided for controlling the pivoting movement of the mounting device 21. It comprises a deflector 28, which is articulated at one end to the stick 14 at a deflector axis 29. The pivoting mechanism 27 further comprises a linkage 31, which is connected at one end to the deflector 28 via a common pivot axis 35. At the opposite end, the linkage 31 engages with a coupling device 33, which is a component of the mounting device 21 or is attached to the mounting device 21. Preferably, the drive housing 66 has an at least partially extending cover surface 67, on which the coupling device 33 is provided, and the pressure cylinder 16, in particular the piston rod of the pressure cylinder 16, engages with the pivot axis 35 of the pivoting mechanism 27.

[0022] 2 shows a schematic enlarged side view of the stick 14. FIG. 3 shows a perspective view of the stick 14 shown in FIG.

[0023] The stick 14 has a main stick portion 50. One end of the main stick portion 50 is a stick bearing point 41, through which the stick 14 is articulated relative to the boom stick 12. Adjacent to this is a stick bearing point 42, in which the stick cylinder 18 of the boom stick 12 engages. A lower side 43, designed as a lower chord, extends from the stick bearing point 41 to a front end 48 of the stick. On the opposite side, the stick 14 has an upper side 45, designed as an upper chord. A pressure cylinder bearing 46 for receiving the pressure cylinder 16 is provided on the upper side 45. The upper side 45 and the lower side 43 are aligned at an acute angle to each other in the direction of the deflector axis 29.

[0024] The stick 14 has a cranked stick portion 51. This cranked stick portion 51 is provided at the stick end 48. The stick 14 comprises a main stick portion 50 with stick bearing points 41 and 42, and the cranked stick portion 51. The mounting axis 17 is provided at the cranked stick portion 51. The cranked stick portion 51 extends from the deflector axis 29 toward the upper side 45 of the stick 14. The cranked stick portion 51 is cranked upward relative to the lower side 43 of the stick 14 at an angle α of, for example, 30°. The angle for the cranked stick portion 21 is determined by two imaginary straight lines 52, 53. The straight line 52 extends through the mounting axis 17 and the deflector axis 29 of the cranked stick portion 51. The straight line 52 extends through the deflector axis 29 and preferably runs parallel to the lower side 43 of the stick 14. A straight line 53 also extends through the deflector axis 29 and the stick bearing point 41 .

[0025] The length of the cranked stick portion 51 can be determined by the angle α and the height HS between the mounting axis 17 and the deflector axis 29. The distance between the mounting axis 17 and the deflector axis 29 includes the height HS.

[0026] The cranked stick portion 51 has the same width as the main portion 50 of the stick 14. In the case of very long sticks 14, the main stick portion 50 can taper towards the cranked stick portion 51. The width of the cranked stick portion 51 and the distance between the side plates 36 of the connecting device 33 are adapted to each other.

[0027] Figure 4 shows a perspective view of mounting device 21. Figure 5 is a schematic side view of mounting device 21 shown in Figure 4.

[0028] The coupling device 33 comprises two side plates 36 arranged at a distance from each other. The side plates 36 can be connected to at least one connection plate 34 extending between the side plates 36. The at least one connection plate 34 can rest on the upper side of the rotation device 22 and is preferably removably fixed thereto. A connection surface 65 is formed between the upper side of the rotation device 22, on which the coupling device 33 is mounted, and the coupling device 33, in particular the connection plate 34 of the coupling device 33. Each side plate 36 comprises a coupling bearing point 37 and a mounting bearing point 38. The coupling bearing points 37 and the mounting bearing points 38 are offset from each other by a height HK. The add-on storage locations 38 are recessed relative to the coupling storage locations 37. The mounting bearing points 38 of the coupling device 33 are located, for example, at the connection level 65. Alternatively, the mounting bearing points 38 can also be offset toward or located in the rotation plane 39 of the rotation device 22. The mounting bearing points 38 are offset laterally outward relative to the mounting device 21 , in particular the rotating device 22 , or are assigned to the end faces of the rotating device 22 .

[0029] The connection bearing point 37 and the mounting bearing point 38 are disposed at an angle β relative to the plane of rotation 39. The angle β is determined by two imaginary straight lines 56, 57. The imaginary straight line 56 extends through the connection bearing point 37 and the mounting bearing point 38. The imaginary straight line 57 extends through the plane of rotation 39 or is aligned parallel to the plane of rotation 39. The imaginary straight line 57 can also be located on a cover surface 67 at least partially formed in the drive housing 66 of the rotation device 22. The mounting bearing point 38 can be located on the straight line 57 or below in the direction of the plane of rotation 39, preferably within the height formed by the straight line 57 and the plane of rotation 39. Preferably, the angle β between the straight lines 56, 57 is in the range of 15 to 60°. In particular, an angle β of 30° is provided. This angle β preferably corresponds to the angle α.

[0030] 6 shows a schematic cross-section along line VI-VI shown in FIG. 4. The rotation device 22 has a flat 69 between the upper side or connection level 65 and the end face 81 of the rotation device 22. This flat 69 can be inclined, for example, at an angle of 45° relative to the connection face 65. The flat 69 can also be provided at an angle, for example, relative to the connection face 85. In particular, this flat 69 can, on the one hand, allow the mounting bearing point 38 of the side plate 36 to be offset closer to the rotation device 22 and / or, on the other hand, allow it to be offset downward relative to the connection face 65. This arrangement is particularly advantageous in that it can reduce the introduction of forces from the stick 14 into the mounting device 21, thereby reducing shear forces acting on the coupling device 33 of the mounting device 21 during operation.

[0031] The coupling device 33 is preferably connected to the rotation device 22 by means of a threaded connection 83. In particular, the one or more connection plates 34 contact the upper side of the rotation device 22 and the flat part 82 of the rotation device 22 and are fixed in particular by means of the threaded connection 83. This removable arrangement of the coupling device 33 relative to the rotation device 22 also enables an increased adaptability, since the coupling device 33 can be exchanged for the rotation drive 24 and the coupling 23.

[0032] By lowering the set height of the attachment device 21, which can be achieved in particular by shifting the mounting bearing point 38 towards or below the connection level 65 in the direction of the rotation plane 39, the kinematics of the stick 14 and the attachment device 21 are improved to the extent that the overload height and / or separation force can be increased. This is especially the case when the mounting bearing point 38 is located in the rotation plane 39.

[0033] The mounting device 21 according to FIGS. 4 to 6 also has the advantage that the integration of the rotary drive 24 and the coupling 23 makes it possible to reduce the number of hydraulic connections for controlling the instrument 25. For example, the number of connections in the coupling 23 can be reduced from five connections to three connections. Two of the connections serve the main function of supplying and returning the hydraulic fluid, in particular hydraulic oil. The third connection is intended for so-called oil leakage. The connection or integration of the coupling 23 in the rotary actuator 24 makes it possible for the hydraulic connections required for controlling the rotary actuator 24 to be provided within the rotary actuator 24 and / or within the coupling 23, as well as to be permanently connected to each other.

[0034] FIG. 7 is a perspective view of the stick 14 according to FIG. 3 and the hinged mounting device 21 according to FIG. 4 connected to the stick 14. A fork-shaped connection 20 is provided between the pivoting mechanism 27 and the mounting device 21. The pivoting mechanism 27 has two deflectors 28, each positioned outside the stick portion 51 and attached to a deflector shaft 29. The deflectors 28 engage with the pivot shaft 35 of the pivoting mechanism 27 opposite each other. The coupling part 31 of the pivoting mechanism 27 is fork-shaped. The coupling part 31 has two coupling arms 64 facing the mounting device 21. Each of the coupling arms 64 preferably engages with the outside of the side plate 36 of the connecting device 33. Each end of the coupling arms 64 is pivotally attached to a connecting bearing point 37, preferably by a pin. On the opposite side of the coupling arms 64, the connecting part 31 comprises, for example, a connecting stick 65. The width of this connecting stick 65 is less than the distance between the two connecting arms 64. The connecting stick 65 may be provided with a recess, by means of which the piston rod of the pressure cylinder 16 can be positioned between them and engage with the pivot shaft 35.

[0035] The height HK of the connection bearing point 37 and the mounting bearing point 38 of the connection device 33 advantageously corresponds to the height HS of the cranked stick portion 51. The height HS is formed by the distance between the mounting axis 17 and the deflector axis 29. The cranked stick portion 51 is provided between the side plates 36. The mounting axis 17 of the cranked stick portion 51 is aligned with the mounting bearing point 38, whereby they are pivotally connected to each other by a bearing pin.

[0036] Figure 8 shows a schematic side view of the stick 14 with the mounting device 21 in a first pivoted or working position. In Figure 9 the stick 14 is shown with the mounting device 21 in another pivoted or working position that differs from the arrangement in Figure 7.

[0037] The stick 14 with cranked stick portion 51 allows the mounting device 21 to pivot in the direction of the underside 43 of the stick 14 at a pivot angle A of up to 60° relative to the imaginary straight line 52. The offset arrangement of the mounting bearing points 38 relative to the connecting bearing points 37 and the cranked stick portion 51 allows the rotation device 22 to be positioned with its axis of rotation approximately parallel or parallel to the imaginary straight line 52.

[0038] 9 shows another pivoted position of the mounting device 21, in the opposite direction to that of FIG. 6. A pivot angle B of up to 160° can be assumed relative to an imaginary straight line 53 passing through the deflector axis 29. This pivoted position can be assumed by the cranked stick portion 51. This results in a pivoted angle of the mounting device 21 relative to the cranked stick portion 51 of up to 220°.

[0039] Figure 10 shows an alternative embodiment of the stick 14. The stick portion 51 is not bent relative to the main stick portion 50. Such a stick 14 is referred to as a straight stick. The upper and / or lower sides of the stick portion 51 and the main stick portion 50 are provided to lie in a common plane. In all other respects, the description of the stick 14 above applies.

[0040] Figure 11 is a perspective view of the stick 14 according to Figure 10 and the attachment device 21 according to Figure 4. The pivoting movement of the attachment device 21 relative to the stick 14 is controlled using a pivoting mechanism 27, which corresponds to the embodiment shown in Figure 7. A fork-shaped linkage 31 is used. This embodiment thus comprises a fork-shaped connection 20 between the pivoting mechanism 27 and the attachment device 21.

[0041] Figure 12 shows an alternative embodiment of the stick 14 shown in Figures 2 and 3. The stick 14 has a cranked stick portion 51 towards the main stick portion 50. In contrast to the embodiment according to Figures 2 and 3, the cranked stick portion 51 according to Figure 12 is fork-shaped. The cranked stick portion 51 has two fork arms 61, which are spaced apart from each other. A deflector axis 29 and a mounting axis 17 are provided on each fork arm 61. Preferably, the distance between the fork arms 61 in the region where the deflector axis 29 is provided is shorter than the distance between the fork arms 61 in the region towards the stick free end 48, where the mounting axis 17 is located. This has the advantage that similar or identical proportions exist for connecting the mounting device 21 to the stick 14, as in the embodiment according to the stick in Figures 2 and 3 and 9.

[0042] 13 is a perspective view of the stick 14 according to FIG. 12 with the attachment device 21 according to FIG. 4 in a pivoted position. A fork-shaped connection 20 is formed between the stick 14 and the attachment device 21. In this embodiment, the pivoting mechanism 27 has a coupling 31 that is, for example, rod-shaped. Alternatively, in this embodiment according to FIG. 12, it may be provided that the coupling 31 can also be designed as a fork-shaped coupling 31 with two connecting arms 64. Preferably, the coupling 31 can be designed as a welded structure, in which two rod-shaped metal sheets are connected to a web, preferably also made of sheet metal, and the rod-shaped metal sheets engage both the pivot axis 35 and the connecting bearing point 37. Alternatively, the welded structure can also be designed as a cast structure.

[0043] Figure 14 shows an alternative embodiment of the stick 15 to that of Figure 11. This embodiment differs from that in Figure 11 in that the stick portion 51 is straight relative to the main stick portion 50. No offset of the stick portion 51 is provided. In all other respects the description of Figure 12 applies.

[0044] Figure 15 shows a perspective view of the stick 14 shown in Figure 14 and the attachment device 21 shown in Figure 4 in the working position. In this embodiment, the swivel mechanism 27 is designed similarly to that of Figure 12. A fork-shaped connection 31 can also be provided as an alternative in this respect.

[0045] FIG. 16 shows a schematic side view of the excavator 11 according to FIG. 1 with an alternative embodiment of the implement 25. The implement 25 shown in FIG. 16 is, for example, a scraper bar. The excavator 11 can be used as a grader by attaching a leveling bar to the attachment 21. Such graders, also known as planers, earth graders, or road graders, allow for the creation of large, flat surfaces in road construction, gardening, landscaping, and the like. Relocating the attachment bearing point 38 of the attachment device 21 to the area between the connection surface 65 and the rotation surface 69 and / or to the flat portion 69 of the rotation device 22 allows for a reduction in the leverage force acting on the leveling bar during the creation of a flat ground. Additionally, there is only one interface between the stick 14 and the attachment device 21, which significantly reduces or eliminates play in the machine parts. The design of the mounting device 21 with the rotation device 22 also makes it possible to align the scraper bar in the direction of movement but parallel to the ground, so that the excavator 11 can be operated as a grader using the movement drive.
