Definitions
- Adjustment device for a mobile working device of a mobile working machine
- the invention relates to an adjusting device for a movable working device of a mobile working machine, in particular for a shovel of a wheel loader or the like. , with a lifting frame and a tilting linkage and with a plurality of end position stops for the implement and the linkage, at least one stop being wedge-shaped and adjustable, such that the stop is adjustable.
- the end positions of the bucket are limited by stops in order to maintain defined positions of the bucket and the lever of the tilting linkage and to avoid undesired angular positions of the levers.
- These end position stops are usually produced by welded steel plates that strike parts of the lifting frame when the machine is in use.
- stops wear during use. To avoid consequential damage, the stops must be welded on from time to time. Reworking the stops is also necessary when replacing the shovel.
- stops are known which are set by shims, but these have the disadvantage that the setting process is very time-consuming.
- a generic adjusting device is known from DE-A-1 913 536.
- a stop is provided which has two oppositely directed wedge surfaces with different inclinations.
- This stop is arranged rotatably about a pin, such that the stop can be brought into the operative position either with one or the other wedge surface.
- the stop can thus be brought into two different operative positions, but the disadvantages described above cannot be remedied with such an adjustment device, since adaptation to the respective installation conditions or wear on the stop surfaces is not possible because only two adjustment options are possible are given by appropriate rotation of the stop.
- the object of the invention is to further develop such an adjusting device in such a way that a simpler and safer and easily adjustable system for setting the stops is provided.
- This task is carried out with an adjusting device of the gangs designated type solved according to the invention in that the adjustable wedge-shaped stop is displaceable in and against the wedge direction and is formed by a wedge-shaped anvil with a displaceable anvil carrier.
- the anvil carrier is provided with elongated fastening holes for displaceable fastening on a sliding surface of a screw-on block arranged on the linkage, lifting frame and / or implement.
- the wedge angle between the inclination of the anvil and the sliding surface is selected such that self-locking is generated on the sliding surface.
- the self-locking ensures that the screw connection does not Must absorb pushing forces.
- the facing surfaces of the anvil carrier and the screw-on block are machined and / or that the stops are attached to the blade between the bearing plates.
- the rocker arm stop is preferably attached to the lifting frame crossbar.
- stops are advantageously arranged below the blade pivot point and an anvil is arranged such that it strikes directly on the lifting frame.
- the anvil is preferably made of non-hardened steel and its strength is equal to or less than that of the lifting frame. If two stops are provided on the implement, it can be provided that only one is designed to be adjustable.
- FIG. 1 is a side view of a wheel loader
- 2 is a perspective view of the adjusting device with a shovel
- 3 is a plan view of the blade of the adjusting device
- Fig. 4 is an illustration of the blade in the articulation area to the linkage
- Fig. 5 is an enlarged perspective view of the attachment of a stop.
- a wheel loader 1 is shown in FIG. 1 as an example of a mobile work machine.
- This wheel loader has a bucket 5 which is connected to the wheel loader 1 in a manner known per se via an adjusting device.
- This adjustment device has a lifting frame 2, a rocker arm 3 and a rocker rod 4.
- the end positions of the bucket 5 in the wheel loader 1 are limited by stops in order to maintain defined positions of the bucket and the lever and to avoid undesired angular positions of the levers.
- a wheel loader 1 for example, it is necessary to limit the path of the bucket 5 with two stops and the path of the rocker arm 3 with one stop in the tilted position.
- a right stop 6 and a left stop 7 are arranged on the blade 5 in the manner described in more detail below on the blade 5, the right stop 6 on the blade 5 right and left stop 7 strikes the left lifting frame spar.
- the rocker arm stop 8 sits centrally on a lifting frame cross member 10 of the lifting frame 2 and limits the rocker arm travel.
- the blade pivot point is designated by 18 in FIG.
- At least one, but possibly also two or all, stops 6, 7, 8 are designed according to the invention in a manner as shown in FIG. 5.
- a stop is formed by a wedge-shaped anvil 15 with a displaceable anvil carrier 17.
- the anvil carrier 17 has fastening elongated holes 14 which are provided for slidable fastening on a sliding surface 11 of a screw-on block 13 arranged on the linkage, lifting frame 2 and / or the shovel 5, wherein fastening screws 16 can be screwed into the screw-on block 13 and an exact position tionation of the wedge-shaped anvil 15 is possible by appropriate displacement of the anvil carrier 17 relative to the fastening screws 16.
- the wedge angle is selected so that self-locking occurs on the sliding surface 11 between the anvil carrier 17 and the screwing location on the screw-on block 13, so that the screw connection (fastening screws 16) does not have to absorb any displacement forces.
