Background Art

[0002] German Utility Model No. 202011100482 discloses an excavator that houses a mounting device at the free end of a stick. This mounting device is connected to a connecting device in the mounting device so as to be pivotable around the mounting axis of the stick. A swivel drive unit is provided in the connecting device, which likewise has a connecting portion on the opposite side of the connecting device for receiving the tool. The mounting device includes a rotating device with a rotational drive unit, whereby the connecting portion can rotate around the axis of rotation with respect to the drive unit housing of the rotating device. Further, another swivel drive unit is provided on the upper side of the drive unit housing, whereby the entire rotating device can swivel around an axis perpendicular to the axis of rotation correlated with the connecting device. This connecting device has a mounting bearing point and a connecting bearing point, both of which are located above the additional swivel drive unit. This results in a large overall height of the mounting device between the mounting bearing point of the connecting device and the connecting portion. This impairs the pivotal movement of the mounting device with respect to the stick.

Summary of the Invention

Problems to be Solved by the Invention

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

[0005] This problem is solved by a mounting device in which the rotating surface is formed between the drive housing and the coupling of the rotating device, and the virtual connecting surface of the fixedly positioned coupling device is formed by at least a partially formed cover surface of the drive housing. Here, the mounting bearing point of the coupling device is located on the virtual connecting surface of at least a partially formed cover surface of the drive housing, or on the rotating surface, or in the region between the connecting surface and the rotating surface, and the coupling bearing point of the coupling device is located above the connecting surface. This arrangement allows the axis of rotation around which the mounting device can pivot to be lowered in the direction of the rotating surface of the mounting device. The axis of rotation of the mounting device is located on the axis of the mounting point, thereby pivotably fixing the mounting device to the mounting axis of the stick.

[0006] Preferably, the coupling device is mounted in the drive housing so as not to rotate and / or pivot. This allows for direct power transmission.

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

[0008] The coupling device is preferably provided detachably at the virtual connection level or in the drive unit housing. Alternatively, the coupling device may be connected to the connection level of the drive unit housing in a single piece.

[0009] Preferably, the coupling device has two side plates, which are detachably mounted on at least a partially extended cover surface of the drive unit housing. As a result, these side plates can also be adapted, depending on the design of the stick or stick end, to achieve a large swivel range of the mounting device. Alternatively, these side plates in the coupling device can be formed integrally with the drive unit housing. This allows for cost-reduced manufacturing, and in particular, it can result in weight reduction.

[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 detachably connected to the rotating device as a single unit. More specifically, at least one connecting plate is provided so that it can be connected to the rotating device by a screw connection. This provides adaptability in that the coupling device is interchangeably provided on the rotating device, thereby allowing application to different sticks by replacing the coupling device.

[0011] The drive housing of the rotating device advantageously has at least one flat surface, or at least a flat surface between a partially formed cover surface and an end face of the drive housing to which the mounting bearing point is assigned. This allows the mounting bearing point to be moved closer to the drive housing. The distance between the axis of rotation of the mounting bearing point in the coupling device and the axis of rotation of the rotating device, to which the coupling is rotatably mounted relative to the drive housing, can be further reduced.

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

[0013] In detail, the distance between the mounting point axis and the rotation axis of the rotating device is intended to be shortened by at least one inclined section. This allows for the creation of an improved force ratio. Additionally, at least one flat section can also be used to reduce the shear force at the spring connection for the coupling device of the rotating device. This means that the threaded cross-section can be reduced.

[0014] According to another advantageous design of the mounting device, at least one connecting plate in the coupling device is provided to be connected to or resting on a flat surface, and at least one other connecting plate in the coupling device is provided to be connected to the top surface of the rotating device. This has the advantage that the shear force generated in the coupling device can be reduced.

[0015] Furthermore, preferably, the mounting bearing points of the connecting device are assigned to a flat portion or end face of the rotating device. This assignment also depends on the positioning of the mounting bearing points between the connecting surface and the rotating surface. This assignment may also depend on the size of the incline, because it can extend at least partially or completely from the cover surface on the opposite side of the end face of the rotating device.

[0016] In another advantageous embodiment, the mounting bearing point and bearing point of the coupling device are positioned at an angle β with respect to the mounting device, and this angle β is formed by two virtual straight lines. The first or one of the virtual straight lines extends through the mounting bearing point and the coupling bearing point, and the second or the other of the virtual straight lines extends to or parallel to the plane of rotation of the rotating device, and is offset from the direction of the cover surface. This offset arrangement of the coupling bearing point and the mounting bearing point in the coupling device allows the mounting bearing point to be offset in the direction of the plane of rotation of the rotating device. This makes it possible to reduce the set height of the mounting device relative to the stick. In detail, this expands the range of swivel angles of the mounting device relative to the underside of the stick.

[0017] Advantageously, the virtual straight line of the mounting device is provided at an angle β of 15–45°, preferably 25–35°. This also enables an advantageous connection of the mounting device to both the straight and cranked portions of the stick.

[0018] Furthermore, preferably, the rotary feedthrough is provided in the drive unit housing. The rotary feedthrough has a stator fixed non-rotatably to the drive unit housing and a rotor that can rotate relative to the stator. The rotary feedthrough is connected to a coupling and to at least one, preferably three, couplings in the coupling. This allows for a compact design of the mounting device. Additionally, internal supply and discharge of the drive fluid from and to the device, or to the coupling, can be enabled. Advantageously, one coupling is provided as a supply line for supplying the working fluid. Another coupling is connected to a supply line for discharging the working fluid, and a third coupling can be provided for leak fluid.

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

[Figure 16] This is a schematic side view of the excavator with alternative working tools compared to Figure 1. [Modes for carrying out the invention]

[0021] Figure 1 shows a schematic side view of the 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 is provided with at least one stick cylinder 18 for actinguating the pivotal motion of the stick 14. At least one pressure cylinder 16 is provided on the stick 14, thereby actinguating a mounting device 21 provided on the stick 14. The mounting device 21 is pivotally mounted on the end of the stick 14 on a mounting shaft 17. The mounting device 21 may comprise a rotating device 22 with a rotary drive unit 24, and a coupling unit 23, which is in particular a quick-change coupling unit. The rotating device 22 comprises a drive unit housing 66. The rotary drive unit 24 allows the coupling unit to rotate along the rotation shaft 26 relative to the drive unit housing 66. A working tool 25 is interchangeably provided on the coupling unit 23. A swivel mechanism 27 is provided to control the swivel motion of the mounting device 21. It comprises a deflector 28. At one end, the deflector 28 is articulated with respect to the stick 14 at the deflector shaft 29. Furthermore, the swivel mechanism 27 comprises a coupling 31, which at one end is connected to the deflector 28 via a common swivel shaft 35. At the opposite end, the coupling 31 engages with a coupling device 33. This coupling device 33 is a component of the mounting device 21 or is attached to the mounting device 21. Preferably, the drive housing 66 has at least a partially extended cover surface 67 on which the coupling device 33 is provided, and the piston rod of the pressure cylinder 16, in particular the pressure cylinder 16, engages with the swivel shaft 35 of the swivel mechanism 27.

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

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

[0024] The stick 14 has a crank-shaped stick portion 51. This crank-shaped 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 crank-shaped stick portion 51. The mounting shaft 17 is provided at the crank-shaped stick portion 51. The crank-shaped stick portion 51 extends from the deflector shaft 29 in the direction of the upper side 45 of the stick 14. The crank-shaped stick portion 51 is bent upward in a crank shape at an angle α of, for example, 30° relative to the lower side 43 of the stick 14. The angle for the crank-shaped bent stick portion 51 is determined by two imaginary straight lines 52, 53. The straight line 52 extends through the mounting shaft 17 and the deflector shaft 29 of the crank-shaped stick portion 51. The straight line 52 extends through the deflector shaft 29 and preferably runs parallel to the lower side 43 of the stick 14. The straight line 53 also extends through the deflector shaft 29 and the stick bearing point 41.

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

[0026] The crank-shaped stick portion 51 has the same width as the main portion 50 of the stick 14. In the case of a very long stick 14, the main stick portion 50 can be tapered toward the crank-shaped stick portion 51. The width of the crank-shaped 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 the mounting device 21. Figure 5 is a schematic side view of the mounting device 21 shown in Figure 4.

[0028] The coupling device 33 comprises two side plates 36 positioned at a distance from each other. The side plates 36 can be connected to at least one connecting plate 34 extending between the side plates 36. The at least one connecting plate 34 can be mounted on the upper side of the rotating device 22, and preferably is removablely fixed thereto. A connecting surface 65 is formed between the upper side of the rotating device 22 on which the coupling device 33 is mounted and the coupling device 33, and more specifically the connecting 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 point 37 and the mounting bearing point 38 are offset from each other by a height HK. The add-on storage area 38 is recessed relative to the coupling storage area 37. The mounting bearing point 38 of the coupling device 33 is located, for example, at the connection level 65. Alternatively, the mounting bearing point 38 can also be offset in the direction of the rotation plane 39 of the rotating device 22, or can be located on this rotation plane 39. The mounting bearing point 38 is offset laterally outward with respect to the mounting device 21, particularly the rotating device 22, or is assigned to the end face of the rotating device 22.

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

[0030] Figure 6 shows a schematic cross-sectional view along the line VI-VI shown in Figure 4. The rotating device 22 has a flat portion 69 between the upper side or connection height 65 and the end face 81 of the rotating device 22. This flat portion 69 can be inclined, for example, at an angle of 45° with respect to the connection surface 65. The flat portion 69 can also be provided at an angle, for example, with respect to the connection surface 85. In detail, this flat portion 69 can, on the one hand, allow the mounting bearing point 38 of the side plate 36 to be shifted closer to the rotating device 22, and / or, on the other hand, allow it to be shifted downward with respect to the connection surface 65. This arrangement is particularly advantageous in that it can reduce the introduction of force from the stick 14 into the mounting device 21, thereby reducing the shear force acting on the connecting device 33 in the mounting device 21 during operation.

[0031] The coupling device 33 is preferably connected to the rotating device 22 by screw connections 83. More specifically, one or more coupling plates 34 contact the upper side of the rotating device 22 and the flat portion 82 of the rotating device 22, and are secured in particular by screw connections 83. This removable arrangement of the coupling device 33 relative to the rotating device 22 also enables improved adaptability, as the coupling device 33 can be replaced relative to the rotary drive unit 24 and the coupling unit 23.

[0032] In detail, the kinematics of the stick 14 and the mounting device 21 are improved to a range in which the overload height and / or separation force can be increased, by lowering the setting height of the mounting device 21, which can be achieved by shifting the mounting bearing point 38 in the direction of the rotation plane 39 to or below the connection level 65. This is especially true when the mounting bearing point 38 is located on the rotation plane 39.

[0033] The mounting device 21 shown in Figures 4 to 6 also has the advantage that the integration of the rotary drive unit 24 and the coupling unit 23 allows for a reduction in the number of hydraulic connections for controlling the device 25. For example, the number of connections in the coupling unit 23 can be reduced from five to three. Two of these connections, namely the supply and return of the working fluid, particularly hydraulic oil, serve as the main functions. The third connection is intended for so-called oil leakage. The connection or integration of the coupling unit 23 in the rotary actuator 24 allows for the provision of the hydraulic connections necessary to control the rotary actuator 24 within the rotary actuator 24 and / or within the coupling unit 23, and for them to be permanently connected to each other.

[0034] Figure 7 is a perspective view of the stick 14 according to Figure 3 and the hinged mounting device 21 according to Figure 4, which is connected to the stick 14. A fork-shaped connector 20 is provided between the swivel mechanism 27 and the mounting device 21. The swivel mechanism 27 comprises two deflectors 28. Each is positioned outside the stick portion 51 and mounted on the deflector shaft 29. These deflectors 28 face each other and engage with the swivel shaft 35 of the swivel mechanism 27. The connector 31 of the swivel mechanism 27 is fork-shaped. The connector 31 has two connecting arms 64 directed toward the mounting device 21. Preferably, each of these connecting arms 64 engages with the outside of the side plate 36 of the connector device 33. Each end of the connecting arms 64 is preferably pivotally attached to a connecting bearing point 37 by a pin. On the opposite side of the connecting arms 64, the connector 31 comprises, for example, a connecting stick 65. The width of this connecting stick 65 is narrower than the distance between the two connecting arms 64. The connecting stick 65 may have a recess so that the piston rod of the pressure cylinder 16 can be positioned between them and engage with the pivot shaft 35.

[0035] In the coupling device 33, the heights HK of the coupling bearing point 37 and the mounting bearing point 38 are advantageously equivalent to the height HS of the crank-shaped stick portion 51. The height HS is formed by the distance between the mounting shaft 17 and the deflector shaft 29. The crank-shaped stick portion 51 is provided between the side plates 36. The mounting shaft 17 of the crank-shaped stick portion 51 is aligned with the mounting bearing point 38, thereby connecting them pivotably to each other by bearing pins.

[0036] Figure 8 shows a schematic side view of the stick 14 with the mounting device 21 in a first pivot or working position. Figure 9 shows the stick 14 with the mounting device 21 in a different pivot or working position, different from the arrangement in Figure 7.

[0037] The stick 14 with the crank-shaped stick portion 51 allows the mounting device 21 to pivot at a pivot angle A of up to 60° with respect to the virtual straight line 53 in the direction of the lower side 43 of the stick 14. The offset arrangement of the mounting bearing point 38 relative to the connecting bearing point 37, and the crank-shaped stick portion 51, allow the rotating device 22 to be positioned approximately parallel or parallel to the virtual straight line 52 with respect to its axis of rotation.

[0038] Figure 9 shows another pivot position of the mounting device 21, in the opposite direction to that shown in Figure 6. A pivot angle B of up to 160° can be assumed with respect to a virtual straight line 53 passing through the deflector axis 29. This pivot position can be assumed by the crank-shaped stick portion 51. This results in a pivot angle of up to 220° of the mounting device 21 with respect to the crank-shaped stick portion 51.

[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 be located in a common plane. In all other respects, the description of the stick 14 described above applies.

[0040] Figure 11 is a perspective view of the stick 14 according to Figure 10 and the mounting device 21 according to Figure 4. The rotational movement of the mounting device 21 relative to the stick 14 is controlled using a swivel mechanism 27 corresponding to the embodiment shown in Figure 7. A fork-shaped connecting portion 31 is used. Thus, this embodiment includes a fork-shaped connecting portion 20 between the swivel mechanism 27 and the mounting device 21.

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

[0042] Figure 13 is a perspective view of the stick 14 according to Figure 12, with the mounting device 21 according to Figure 4, in the pivot position. A fork-shaped connector 20 is formed between the stick 14 and the mounting device 21. In this embodiment, the pivot mechanism 27 has a connector 31, for example, which is rod-shaped. Alternatively, in this embodiment according to Figure 12, the connector 31 may also be provided to be designed as a fork-shaped connector 31 with two connecting arms 64. Preferably, the connector 31 can be designed as a welded structure, where two rod-shaped metal sheets are connected to a web, preferably also made of sheet metal, and the rod-shaped metal sheets engage with both the pivot shaft 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 compared to Figure 11. This embodiment differs from the embodiment in Figure 11 in that the stick portion 51 is in a straight line with respect to the main stick portion 50. There is no offset of the stick portion 51. In all other respects, the description in Figure 12 applies.

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

[0045] Figure 16 shows a schematic side view of the excavator 11 according to Figure 1, with an alternative embodiment of the tool 25. The tool 25 shown in Figure 16 is, for example, a scraper bar. The excavator 11 can be used as a grader by attaching a leveling bar to the mounting device 21. Such a grader, also called a planer, earth grader, or road grader, makes it possible to create a wide, flat surface in road construction, gardening, landscaping, etc. By repositioning the mounting bearing point 38 of the mounting device 21 to the area between the connection surface 65 and the rotating surface 69, and / or to the flat portion 69 in the rotating device 22, it is possible to reduce the lever force acting on the leveling bar while creating a flat ground. Additionally, there is only one interface between the stick 14 and the mounting device 21, thereby significantly reducing or eliminating play in the mechanical parts. The design of the mounting device 21 with the rotating device 22 also allows the scraper bar to be aligned with respect to the direction of movement, but parallel to the ground, thereby enabling it to be operated as a grader using the moving drive unit of the excavator 11.
