Definitions
- the invention relates to a mobile implement, particularly for demolition work suitable is.
- Demolition excavators which have a demolition tool, e.g. a Demolition shears, wear.
- the boom has two or more against each other swiveling sections to the height at which the demolition tool works, is determined by the angular position of the two sections: Demolition tools work at great heights, then the upper section of the Outrigger with the swung up lower section an obtuse angle. Should the demolition tool work at a lower height, then the upper section pivoted downwards relative to the lower section. But that’s how it works Tool tipping moment increased. This creates the risk that the Tool tipped over. This danger can be caused by swiveling the lower one back Section of the boom can only be counteracted to a limited extent. Such demolition excavators therefore have only a limited working area in which they work stably can. You need a heavy chassis that can prevent tipping.

- On a pivot bearing 120 of the A boom arm 112 is articulated to a hydraulic cylinder 122. Hydraulic cylinder 122 attacks demolition tool 102. As a result, the demolition tool 102 is opposite the boom arm 112 pivotable.
- the boom arm 112 and the demolition tool 102 can in this case be retracted Machine part 10 can be pivoted almost completely around the pivot bearing 114, so that the boom arm 122 and the demolition tool substantially over the Machine part 10 are "folded". Then it is by gravity on machine part 10, boom arm 112 and demolition tool 102 torque exerted if possible low. Overcoming this torque, the telescopically extendable Machine part 10 are pivoted upwards from the actuating cylinder 100, as in FIG. 9 is shown.
- the machine part 10 can then be extended telescopically from this position. This is also shown in Fig.9. So that the boom arm 112 with the Demolition tool 102 moved straight up. The demolition tool 102 can then operate at high altitude. The demolition tool 102 can be reaching around obstacles. To a limited extent, the demolition tool 102, such as is indicated in Fig.9, also work at different heights without this Machine part 10 needs to be retracted.
- the telescopically extendable machine part 10 can for structural reasons often only a smaller number of pressure medium hoses than functions to be controlled are available. For example, there are only two Pressure medium hoses for flow and return are available. However, there are four to control various functions, namely the pivoting of the boom arm 112 by means of the actuating cylinder 116, the pivoting of the demolition tool 102 by means of of the actuating cylinder 122, a rotation of the demolition tool 102 relative to the Boom arm 112 about an axis 126 and the opening and closing of the Demolition tool, e.g. a demolition shear 102. To control these four functions two remote-controllable valve units 128 and 130 are provided.
- Valve units 128 and 130 are located on the boom arm 112. This is shown in FIG. 10 shown.
- the valve unit 128 is connected via two pressure medium hoses 132 and 134 the flow or return connected.
- the valve unit 130 is over two Pressure fluid hoses 136 and 138 are also connected to the flow and return lines. The connection is established via the adapter piece 110.
- the valve unit 128 controls the two pressure medium hoses 140 and 142 Actuating cylinder 116, which pivots the boom arm 112.
- the valve unit 128 controls continue via two pressure medium hoses 144 and 146 the actuating cylinder 122, which the Demolition tool 102 pivoted.
- the demolition tool 102 is controlled via the valve unit 130.
- the valve unit 130 is via two pressure medium hoses 148 and 150 with an actuating unit 152 connected, which rotates the demolition tool 102 about the axis 126.
- the Valve unit 130 is also connected to a pressure medium hose 154 and 156 Actuator 158 connected by which the opening and closing of the Demolition tool 102 e.g. the demolition shear.
- Fig. 11 The embodiment of Fig. 11 is similar to the embodiment of Figs. 9 and 10. Corresponding parts have the same reference numerals as there.
- a boom arm 112 in a pivot bearing 170 pivoted On the adapter piece 110 at the end of the inner section 16 of the telescopic extendable machine part 10 is a boom arm 112 in a pivot bearing 170 pivoted.
- the formation of the adapter piece 110 and the boom arm 112 and the arrangement of the pivot bearing 170 is such that the boom arm 112 by one large angle of about 180 ° to the telescopically extendable machine part 10 is pivotable.
- a swing arm 172 is also in the adapter piece 110 a pivot bearing 174 is pivotally mounted.
- the rocker arm 172 is via a coupling 176 connected to the boom arm 112.
- a hydraulic actuator in the form of a hydraulic actuating cylinder 178 acts between a pivot bearing 180 on the Boom arm 112 and rocker arm 172.
- Fig.11 the boom arm 112 is in two Positions shown.
- the actuating cylinder 178 is only in the for the sake of clarity pivoted position of the boom arm 112 drawn.
- the kinematic transmission with the rocker arm 172 can optionally be omitted. Then the actuating cylinder attacks directly on the boom arm.
- boom arm 112 in turn is telescopically extendable.
- the demolition tool 102 which is pliers-like here, faces each other the boom arm 112 movable.
- the demolition tool 102 is in a pivot bearing 180 articulated to the free end of the boom arm 112.
- a rocker 184 is pivotally mounted in a pivot bearing 182.
- the swingarm 184 is connected to the demolition tool 102 via a coupling 186.
- a hydraulic actuating cylinder 188 At the Swing arm 184 attacks a hydraulic actuating cylinder 188.
- the actuating cylinder 188 is on the boom arm 112 articulated in a pivot bearing 190. It can also be seen here that by adjusting the demolition tool 102 on the swing arm 184 and Coupling 186 existing kinematic gears a much larger swivel angle is achievable than in the arrangement according to FIG. 10, in which the hydraulic Actuating cylinder 122 directly between boom arm 112 and demolition tool 102 is effective.
- FIG. 12 shows an embodiment with a mobile working device 194, the one has two-part arm 196, wherein a support module 198 for a telescopic extendable machine part 10 instead of the upper section 200, indicated by dashed lines of arm 196 is releasably attached to lower portion 202 of arm 196.
