Definitions
- the invention relates to a mobile working device, in particular a car sound pump, with a chassis, with two front and two rear, extendable from a driving position in at least one support position and by means of a telescopic support leg under lifting the chassis on a support surface support brackets, and with each one measuring member for determining the support force in the support legs, wherein the support legs depending on an upper connection point with the associated support arm connected upper telescopic member and one relative to this displaceable, at a lower end at a lower junction with one on the ground supportable support foot connected lower telescopic link have.
- Mobile implements of this type are provided with extendable support arms, which are intended to improve the stability of the implement at the place of use.
- the support arms have the task of eliminating the vehicle impact and of lifting the wheels off the ground.
- the support arms should reduce the danger of tipping, which results when high tilting moments occur over a work boom.
- the support legs of the support booms form the corners of a quadrilateral whose side lines describe an area within which the overall center of gravity of the implement must be in order to ensure stability. Since the projecting work boom is rotatable, the overall center of gravity during a rotation describes a full circle, which must lie within the quadrilateral area in the work area of the work jib.
- a force sensor pair is arranged in the foot part of each support leg.
- Each force sensor is arranged there in an electrical measuring circuit for delivering a support load-dependent measurement signal, wherein the monitoring device comprises evaluation electronics which can be acted upon in predetermined scanning cycles with the support foot-related support load measurement values and their comparison with at least one predetermined stability value-determining threshold value.
- the evaluation electronics include a software routine for determining the second lowest stem-foot-related stem load value of each sampling cycle and comparing it with a stability-determining threshold.
- the Anlenkbolzen carries in the region of its bearings at least one strain gauge to determine the shear deformation. Comparative measurements with force measurements taken directly on the foot plate have shown that in the support force measurement with the arrangements described can lead to systematic incorrect measurements, which preclude a reliable stability monitoring.
- the object of the invention is to improve the support structure of the known implements to the extent that an exact support force measurement is possible.
- the solution according to the invention is based on the recognition that frictional forces occur in the force transmission systems arranged inside the support legs for the support force measurement, which leads to a falsification of the measurement at the measuring point. So there are force paths for the power transmission, which do not run over the actual measuring point.
- the aim of the invention is therefore to eliminate frictional forces within the power transmission system by the mutually moving parts of the power transmission system are mounted floating relative to each other.
- the upper telescopic member with a thrust piece in a sleeve-shaped receptacle with radially centered clearance arranged on the support arm rests axially against a force introduction point on the measuring member under the action of the supporting force.
- the receptacle has a cladding tube which is rigidly connected to the support arm and in which the upper telescopic member can be displaced axially unhindered with radially centered play.
- a preferred embodiment of the invention provides that the radial clearance between the cladding tube and the upper telescopic member is bridged by at least two axially spaced-apart, elastically deformable support rings, which cause the centering.
- the support rings can be elastically deformable.
- the elastically deformable support rings in the circumferential direction zigzag, lamellar or meander-shaped and / or slotted.
- the upper telescopic member is articulated with the arranged at its upper end side of the pressure piece by means of a transverse to the telescopic axis through the receptacle or the cladding passing through the pivot bolt on the support arm, wherein the pivot pin is designed as a measuring member.
- the articulation bolt has at least one strain gauge for determining the pin bending or shearing deformation as a measure of the supporting force.
- a further improvement of the friction-free support force transmission system is achieved in that the pressure piece and the upper telescopic member are axially coupled to each other at mutually complementary, spherically curved end face coupling surfaces.
- Another improvement tion in this regard is achieved when the lower telescoping member carries a downwardly projecting Stauerfußkugel, while the foot has a bearing cup for receiving the Stauerfußkugel.
- the foot part may carry an upwardly projecting support foot ball, while the lower telescopic member has a bearing socket for receiving the support foot ball.
- the support leg with a pressure piece in a arranged on the lower telescopic member recording with radially centered game under the action of the supporting force abuts axially against a force introduction point of the measuring element.
- the receptacle in this case advantageously has a measuring bell which is rigidly connected to the lower telescopic member, while the foot part has a support base ball mounted in a bearing cup, wherein the pressure member is formed either on the support ball or on the bearing cup.
- the pressure piece engages with radial clearance from below into the measuring bell and lies there under the action of the supporting force axially against the measuring member and is secured against falling out.
- the radial play between pressure piece and measuring bell is bridged in this embodiment by at least two axially spaced from each other, elastically deformable support rings, which cause the centering.
- the support rings are expediently elastically deformable, for example, by being shaped and / or slotted in a zigzag, lamellar or meandering manner in the circumferential direction.
- the pressure piece has a circumferential groove which is partially penetrated by two diametrically opposite, supported on the measuring bell locking pins. The force measurement takes place with the help of a Measuring member having at least one acted upon by the pressure element with the supporting force force sensor.
- the measuring element additionally has an internal and / or external measuring electronics, which is connected either to externally guided power and signal lines or a transmitter or a transceiver for wireless Has measured value transmission.
- an internal and / or external measuring electronics which is connected either to externally guided power and signal lines or a transmitter or a transceiver for wireless Has measured value transmission.
- this is advantageously overlapped by a wound bellows, in which the lines for the power supply and / or the signal transmission can be integrated.
- a wireless, for example inductive power supply is conceivable.
- each measuring element has two redundant force sensors with measuring electronics and transmitters for data transmission.
- each sensor or each redundant force sensor with measuring electronics can be assigned a rechargeable battery.
- a simple charging of the battery is made possible by the fact that between the telescopic members of the support legs a primary side connected to an AC power source and secondary side via a charging circuit to the battery connected inductive power supply line having a primary and secondary coil disposed on each one of the telescopic members and are activated only in the retracted state of the telescopic links.
