Definitions

  • the invention relates to a removable frame for a loader device, in particular for a front loader, telescopic loader, skid steer loader, swing loader, wheel loader or Hoflader.
  • Front loaders, telehandlers, skid steers and others are loader devices intended to carry out batching, grading, shoveling, clearing, etc.
  • the charger device has one or more pivotable arms on which or on which a working tool is attached.
  • a front loader two booms are provided, which are usually coupled together by cross braces and can be raised and lowered by means of lifting cylinders.
  • the telehandler has only one boom.
  • a tilting movement of the tool at the end of the or the boom can be performed.
  • the boom or arms can be provided variable in length in order to increase the radius of action for the tool.
  • removable frame In order to equip the boom or arms modularly with different tools, are in the art used so-called removable frame.
  • a removable frame is exemplary in the FIG. 1 shown and designated by the reference numeral 1 '.
  • the removable frame 1 ' is coupled to the two arms 100' of a charger device, not shown.
  • the removable frame 1 ' has a frame 2' on which a tool, not shown, such as a blade or a fork can be attached.
  • the frame 2 ' has an upper and lower beam 3' and 4 ', which are connected to each other via side plates 5' and 6 'and together span the substantially rectangular frame 2'.
  • To stabilize or reinforce the removable frame 1 'further struts can be provided, which in the FIG. 1 are indicated.
  • the interchangeable frame 1 ' communicates with hydraulic devices 101' of the arms 100 'in connection with which a tilting movement of the interchangeable frame 1' and thus possibly a tool attached thereto about a substantially horizontal axis B 'can be realized
  • the removable frame 1 'of FIG. 1 is connected to the one degree of freedom of pivoting about the horizontal axis B 'fixed to the arms 100. Furthermore, the removable frame 1 'on no further degrees of freedom for tilting, rotating or pivoting of the tool. In particular, with the conventional removable frame a lateral inclination compensation, such as an uneven load distribution or an inclination of the charger device in the field is not possible. Any flexibility of the tool is not necessarily desirable, since this usually requires technically complex structures that are maintenance-prone and can affect the robustness or stability.
  • the US 5,562,398 describes a skid steer loader in which the tool, which is here a blade, can be rotated about a horizontal longitudinal axis in addition to the degree of freedom described above.
  • the skid steer loader has two parallel boom, at the end of which there is a plate which is connected via a rotary member with the blade.
  • the rotary shaft in the longitudinal direction is located centrally between the two arms and in the upper part of the plate.
  • the rotation about the horizontal longitudinal axis takes place in the US 5,562,398 hydraulically and for the purpose of lateral tilting of material from the blade, whereby comparatively large tilt angles about the horizontal longitudinal axis can be realized.
  • An object of the invention is to provide a removable frame for a charger device, which allows a side slope compensation of the charger device in a technically robust, compact, lightweight and low-maintenance manner.
  • the interchangeable frame according to the invention is coupled or coupled to one or more arms of a loading device, such as a front loader, telescopic loader, skid steer loader, swing loader, wheel loader or Hoflader.
  • the charger device is usually a vehicle, such as a tractor. Due to the position and position of the charger device in the state of use, the terms “right”, “left”, “top” and “bottom” are uniquely determined. Thus, the positions of a “horizontal longitudinal axis”, “horizontal plane”, “vertical plane”, “width direction”, “longitudinal direction”, etc. are also clearly determined.
  • the removable frame is connected or connectable with a tool.
  • the removable frame as a module for receiving and replacing different tools, such as for example, a shovel, a fork, etc. provided.
  • the exchangeable frame is pivotable about a horizontal axis in the width direction of the loading device relative to the cantilever and the cantilevers, respectively.
  • the removable frame according to the invention has a mechanism for tilting the tool about a compensating axis.
  • the compensating axis extends substantially horizontally and in the longitudinal direction with respect to the loading device.
  • the removable frame additionally permits tilting about the longitudinal axis.
  • the compensation axis is offset to the right or left from a vertical plane which intersects the center of gravity of the removable frame.
  • the compensation axis is thus not in a plane which bisects the rectangle symmetrically in the vertical direction.
  • the compensation axis is thus offset laterally, to the right or left of the center of the removable frame. Due to the lateral position of the pivot point for pivoting about the compensation axis of the desired lateral inclination compensation is accomplished with little force. A central pivot point would require considerable design effort to stabilize the rotation, especially in the case of large and very unevenly distributed loads.
  • the interchangeable frame of the invention has a low weight and avoids a significant visual obstruction, which would be present in the case of a central pivot point.
  • the lateral displacement of the fulcrum and the associated advantages are, among other things, therefore technically useful, because for the purpose of side slope compensation no very large swivel angle must be achieved.
  • the compensation axis intersects the removable frame in the lower area.
  • the compensation axis intersects the rectangle in the lower half with respect to a horizontal bisector, preferably the compensation axis intersects the change frame in the vicinity or directly on the lower side.
  • the compensation axis preferably extends substantially through a lower corner of the frame. It is further preferred that the compensation axis is substantially perpendicular to the rectangle.
  • the degree of lateral inclination compensation to be made depends not only on the position of the loading device in the field and on the load distribution on the tool, but also on the position of the boom (s) and the tilting angle about the horizontal axis in the width direction. Depending on the position of the boom and the conventional tilt angle leads a lateral inclination compensation to the compensating axis, possibly also to an undesirable rotation about one or more other axes. For this reason, the tilting about the compensation axis can be accomplished so that not desired rotation angle can be compensated.
  • the compensation axis is not exactly perpendicular to the removable frame or the plane spanned by the removable frame level. Rather, deviations by a few degrees are possible.
  • the position of the compensation axis relative to the removable frame may even change depending on the tilt angle about the compensation axis.
  • the tilting about the compensating axis is effected via a hydraulic actuating means.
  • one or more hydraulic cylinders can be provided, the or which is preferably provided on the compensation axis of the opposite side of the removable frame or, with respect to the vertical plane which intersects the center of gravity of the removable frame.
  • the adjustment of the tilt angle about the compensating axis can be done manually or automatically, in particular electronically.
  • a sensor may be provided which measures the inclination of the loading device in the field and / or the load distribution on the tool and then adjusts the optimal tilt angle about the compensating axis.
  • the removable frame on a rail and a roller, which cooperate technically to guide the tilting movement about the compensating axis.
  • the rail and the roller are provided on two parts of the removable frame, which are pivotable relative to each other about the compensation axis.
  • the rail and the roller are preferably located on the opposite side of the compensating axis of the removable frame, with respect to the vertical plane which intersects the center of gravity of the removable frame.
  • the rail and the roller are located as far as possible on the lateral edge of the removable frame, which is opposite to the edge on which the compensation axis is located.
  • the rail is preferably curved along a contour that corresponds to the tilting movement about the compensating axis. In other words, the rail preferably describes approximately a circular arc around the compensation axis.
  • a guiding means and a guided means are provided, which cooperate technically to stabilize the tilting movement about the compensation axis.
  • roller and rail are mentioned for the sake of simplicity, the corresponding features can be applied generally to the guide means and the guided means.
  • the guide means may be curved as described above and below.
  • the rail is also curved in a direction that is not in the plane of the above circular arc, or more generally, is not in the plane perpendicular to the balance axis.
  • the curvature along such additional direction is intended to compensate for rotations about "unwanted" axes of rotation that may occur depending on the location of the tool, as described above. If such a compensation is to take place, the position of the compensation axis is variable as a function of the pivoting angle about the same.
  • Such mobility can be realized for example via a ball joint at the pivot point on the compensation axis.
  • the removable frame is intended and suitable for use with a front loader or telehandler.
  • a side slope compensation of the type described above is desirable.
  • the side tilt compensation mechanism can be made in a technically simple, robust, lightweight and low maintenance manner, without significant obstruction, without requiring constructive adjustment of the loader device and / or the tool.
  • the FIG. 2 shows a removable frame 1, which is attached to two arms 100 of a loading device, not shown beyond.
  • the removable frame 1 has a rectangular frame 2, which in turn is composed of an upper 3 and lower 4 spar and a right 5 and left 6 side plate and spans a rectangle.
  • Other elements for stabilizing or reinforcing the removable frame 1, such as struts can be provided and are in the FIG. 2 indicated, but unspecified.
  • the removable frame 1 is attached via hydraulic cylinder 101 to the arms 100, so that the removable frame 1 to a horizontal axis in the width direction B can be tilted forward and backward.
  • the removable frame 1 can be tilted about a compensating axis A, which is approximately perpendicular to the rectangle that is spanned by the frame 2.
  • the removable frame 1 is shown in three positions to show the lateral tilting movement about the compensating axis A.
  • the pivot point of this tilting movement is located approximately in the lower left corner of the frame 2 spanned by the rectangle.
  • the fulcrum is thus offset laterally from a vertical plane which intersects the center of gravity of the removable frame 1.
  • the here mentioned vertical plane is in the FIG. 2 not shown; it stands vertically on the frame 2 and bisects it in the vertical direction.
  • the emphasis here is on the geometric center of gravity of the frame 2.
  • An actuating means for pivoting the frame 2 about the compensating axis A such as a hydraulic cylinder is provided, but in the FIG. 2 for the sake of clarity not shown.
  • FIGS. 3 to 5 a removable frame 1, which is provided for attachment to a telescopic boom 102 of a telehandler.
  • FIG. 3 a front view of the removable frame 1
  • FIG. 4 a side view
  • FIG. 5 a top view.

  • a removable frame 20 is attached.
  • the exchangeable frame 20 is about a horizontal axis in the width direction B tiltable.
  • the removable frame 20 is connected via a shaft 103 with the telescopic arm or telescopic boom 102.
  • the removable frame 20 is rotatable about the compensating axis A, which is laterally offset from the center of the rectangular frame 20 by a distance a.
  • the vertical plane which intersects the interchangeable frame in the geometric center of gravity is denoted here by VE.
  • VE The vertical plane which intersects the interchangeable frame in the geometric center of gravity
  • FIGS. 3, 4 and 5 also a rectangular frame is clamped.
  • the plane of the rectangle is in the FIG. 3 the paper plane and stands in the FIGS. 4 and 5 perpendicular to the paper plane.
  • the change frame 20 is shown in three tilted positions about the compensating axis A.
  • this figure shows a hydraulic cylinder 21, which causes the tilting movement about the compensating axis A via a pin 22 and a slot 23. The movement is guided by a sliding of the pin 22 in the slot 23.
  • FIGS. 6, 7 and 8 Another embodiment of the removable frame 40 is in the FIGS. 6, 7 and 8 shown.
  • the FIG. 6 shows a front view of the removable frame 40 in the tilted state.
  • the FIGS. 7 and 8 are detailed views of the actuating mechanism for tilting the removable frame 40th
  • FIG. 6 shows an upper spar 41 and a lower spar 42 forth, which span together with side plates 43 and 44 a rectangular, tiltable frame.
  • the tiltable frame is tiltable relative to a base portion 45 of the removable frame 40, which in turn can be connected to brackets, not shown, of a loading device.
  • FIG. 6 a hinge 46 is shown about which the frame 41, 42, 43, 44 is tiltable.
  • the compensation axis A, to which the Tilting movement occurs, is approximately perpendicular to the plane of the paper FIG. 6 and passes through the hinge 46.
  • FIGS. 7 and 8 are detailed views of the actuating mechanism for tilting the frame 41, 42, 43, 44 about the compensating axis A.
  • the movement is effected by a hydraulic cylinder 47.
  • a guide takes place along a rail 48.
  • a roller 49 runs on a running surface of the rail 48, whereby the tilting movement is guided and stabilized about the compensating axis A.
  • the rail 48 is curved both in the plane which is perpendicular to the compensating axis A, and along a component perpendicular thereto. This can be compensated for a typical position of the boom and the tool unwanted rotational components in the side slope compensation.
  • the exemplary embodiments presented above realize the invention in a technically robust and low-maintenance manner.
  • the removable frame shown are relatively easy and are actuated by a technically particularly simple operating mechanism, which is particularly possible because the compensation axis is not centrally provided with respect to the removable frame, but laterally offset.
  • the lateral inclination compensation system shown here is suitable for wheel loaders (loaders), front loaders (for tractors, tractors), telescopic loaders, swing loaders, skid steer loaders and reciprocating loaders (which can also be laterally offset) with or without telescopic unit.
  • the lateral tilt compensation mechanism is part of or provided on the removable frame. Thereby, it is not necessary that the tools and / or arms of the charger device in a special way for this additional Functionality to be adjusted. Due to the comparatively low inclination movement (a very large inclination movement is not required for the lateral inclination compensation described here), a very compact design with low additional weight can be realized. In addition, the additional functionality of the side tilt compensation can be produced inexpensively, it is insensitive to dirt and extremely durable. Hydraulic actuation is preferred.
