Definitions
- OMS Outrigger Monitoring System
- the invention relates to a working device, comprising a base on which at least one support element and / or a counterweight is arranged, according to the features of Oberbergriffes of claim 1.
- Working devices such as fixed or mobile cranes having a base such as a lattice boom in a fixed crane or a vehicle chassis with wheels, chains or the like and a drive unit in a mobile crane having a support member and / or a counterweight are known.
- Support elements especially in mobile cranes are required that they are extended at the site, whereas they are otherwise retracted especially when driving the crane. These support elements are extended to increase the stability of the crane and also to increase its application area during work. This can also counterweights, as well as. in stationary cranes, are used, which are arranged on the base or on another attachment of the crane (generally the working device), for example, to attach and move higher weights and cantilevers of cranes. Properly extended support members and / or properly sized and attached counterweights are essential to the safety of the work apparatus.
- the invention is therefore an object of the invention to provide a working device with which the above-described disadvantages are avoided, in particular, the security risk is to be reduced or even completely excluded and thus the operation of the working device safer.
- a radio base is arranged at the base of the working device and a radio unit cooperating with the radio base by means of wireless signal transmission is arranged on the supporting element and / or the counterweight.
- a radio base is arranged at the base of the working device or another unit arranged on the base. Associated with this is on the support element, preferably on each support element (if there are several) and / or the counterweight (or at least on a part of a counterweight, if this is composed of several parts to form a total counterweight) arranged a radio unit.
- the radio base cooperates with the radio units by means of wireless signal transmission. This has the advantage that the structure is very simple and no cables need to be laid. It is only necessary to provide the working device at a certain location fixed to the radio base and at the same time to arrange the cooperating radio unit on the at least one support element and / or the counterweight.
- the radio base and / or the radio units are equipped with a stand-alone power supply (for example, battery (replaceable) or rechargeable battery (rechargeable)). As a result, these units can also be retrofitted to existing working devices.
- a stand-alone power supply for example, battery (replaceable) or rechargeable battery (rechargeable)
- Signal transmission is wireless, bidirectional, either single or redundant. This ensures a fast, uncomplicated and secure data transfer.
- the radio base and the radio unit on the support element and / or the radio unit on the counterweight Via the wireless signal transmission between the radio base and the radio unit on the support element and / or the radio unit on the counterweight, it is possible to determine the relative position of the support element and / or counterweight with respect to the base (or the part to which the counterweight the base is cultivated). Due to the detection of the relative position between the base of the working device and the support member, it is possible to detect in which position the support member is located with respect to the base. In this way it can be detected whether the support element is fully retracted or fully extended or is in an intermediate position.
- counterweights are attached in a certain weight for balancing the working device.
- this intended location is known and also the location of the radio base at which it is located at the base, can be determined via a radio link between the radio unit to the counterweight and the location of the radio base, whether on the one hand, the counterweight with its radio unit itself in the vicinity of the working device (or has been omitted if necessary) and whether it has been arranged at its intended location or not.
- a working device has both at least one supporting element and at least one counterweight
- all radio units of the support elements interact with their own radio base and the at least one radio unit of the at least one counterweight with its own, provided separately and arranged radio base.
- more than one support element for example four support elements
- a part of the support elements are grouped together (for example the front and rear support elements or the right and left support elements) and each group interacts with a radio base.
- the radio base is arranged in a center of the base in which a longitudinal axis and a transverse axis of the base intersect.
- This central arrangement of the single radio base is advantageous if only a single radio base is present, which is intended to cooperate wirelessly with in each case one radio unit of the at least one support element or the counterweight. In this case, it can be assumed that this central arrangement ensures that unhindered establishment of a wireless signal connection between the single centrally arranged radio base and the radio units arranged around it.
- the radio unit is arranged on the support element at its end facing away from the base.
- a sensor device which detects the position of the supporting element and / or the counterweight in relation to the working device.
- a sensor device would not be necessary for this purpose, because the relative position of the radio unit with respect to the radio base can already be detected by the wireless signal transmission, this is a double security. Only then, for example, when the interaction of radio unit the support member and radio base at the base of the working device determine that the support element is completely retracted and this is also detected (confirmed) by the additional sensor device, it can be concluded that the working device can or should move and accordingly Work is to be prevented.
- a preferred application of the invention is seen in work vehicles, in particular mobile cranes (which have support elements and counterweights) and stationary cranes, such as lattice boom cranes, which have counterweights.
- any other working device such as construction or agricultural vehicles, are equipped with the components according to the invention, which operate as described above.
- Figure 1 To clarify the structure and operation of an exemplary working device, reference is made to Figure 1 and the following description.
- Figure 1 shows, as far as shown in detail, as a working device, a mobile crane 1, which has a base 2.
- the base 2 includes drive units, chassis, drive wheels or chains to name only the most essential components of the base 2 of the mobile crane 1.
- the mobile crane 1 comprises a car 3, for example, rotatably mounted on the base 2, from which the operation of the mobile crane 1 is controlled. During operation, a basically illustrated boom 4 is moved, thereby moving loads.
- At least one support element here by way of example four support elements 5, are present.
- This support elements 5 are vertically movable according to the arrow, that is, that they can be retracted (to drive the mobile crane 1 from one site to another site) or can be extended to support the mobile crane 1 during his work can.
- a counterweight 6 can be attached while working, but this is optional depending on the construction of the mobile crane 1.
- the mobile crane 1 shown in FIG. 1 has extended supporting elements 5 and at least one counterweight 6 attached to the car 3, for example.
- the counterweight 6 to be attached it should be noted that in this exemplary embodiment this is attached to an attachment (namely, the car 3) of the base 2.
- the counterweight for example is attached directly to the base 2 or it is also conceivable that both a counterweight to the base 2 and a further counterweight to an attachment of the crane (as here, for example, on the car 3rd ) is appended.
- a radio base 7 is arranged on the base 2.
- the radio base 7 is arranged at any point of the base 2, which can also be arranged centrally.
- the radio base 7 cooperates with radio units 8 on the support elements 5 and a radio unit 9 on the counterweight 6. Due to the wireless data transmission between the radio base 7 on the one hand and the respective radio unit 8 and 9 on the other hand can be detected for example by transit time measurement, whether the respective support member 5 is completely retracted, completely extended or is in an intermediate position. In addition, it can be determined in the same way whether the counterweight 6 is attached to the base 2 or to the car 3 or any other attachment to the base 2 of the mobile crane 1.
- a radio base 7 could be provided for the two front radio units 8 (as viewed in Figure 1, the two left radio units 8), with a radio base at the right end of the base 2 (as viewed in Figure 1) 7 is used for the signal transmission with the associated radio units 8 and / or the radio unit 9.
