Definitions
- the invention relates to a method and a device for monitoring at least one stability parameter of a loading crane mounted on a vehicle, wherein the vehicle is supported or can be supported on the ground in cranes via wheels and support elements separate from the wheels.
- the support elements are extendable in the vertical direction support legs, which are mounted on a laterally extendable in the horizontal direction Abstauerverbreiterung.
- the property of the extensibility of the support legs and the Abstauerverbreiterung is made possible by a telescopic construction.
- the relevant in the context of the invention vehicles usually have either one or two such Abstweilverbreiterept with two support legs.
- the object of the invention is to avoid the disadvantages described above and to provide a comparison with the prior art improved solution for stability monitoring of a mounted on a vehicle loading crane.
- One of the basic ideas of the invention is thus that not only the contributions of the supporting elements, but also the contributions of the wheels to the size of at least one stability parameter are detected and this quantity is compared with at least one predetermined limit value.
- At least one warning signal (to the operating personnel of the crane) is output and / or at least when the limit value is exceeded or undershot a measure to Retention of the limit carried out.
- These include in particular correction movements of the boom system.
- the number a of the wheels and supporting elements, via which the vehicle is supported on the ground, and / or the force-stability coefficient S F is monitored as a stability parameter, wherein S F is calculated from the support forces F, provided via the wheels and the supporting elements becomes.
- the calculation of S F preferably takes place according to the following formula:
- a tot is the total number of wheels and support elements
- a min a predetermined minimum number of wheels and support elements over which the vehicle must be supported at least on the ground
- F,, max the (a m , n -1) indicate the largest supporting forces.
- the axle load is the proportion of the total mass (net mass and mass of the load of a vehicle) that is allocated to an axle (a wheel set) of that vehicle.
- the maximum possible Entfederungsweg corresponds to the way in which a wheel lifts off the ground and the support provided by this wheel assumes the value zero. This approach is particularly suitable for vehicles that have leaf springs with a linear spring characteristic.
- r tot is the total number of wheels
- r min is a predetermined minimum number of wheels over which the vehicle must be supported at least on the ground
- L rest the residual lengths of the vibration damper until lifting the wheels
- L grenz the limit lengths of the vibration damper, in which the wheels stand out from the ground
- max the (r m , n -1) largest residual lengths of the vibration damper specify.
- Protection is also desired for a device for monitoring at least one stability parameter of a loading crane mounted on a vehicle, wherein the vehicle can be supported on the ground by wheels and by support elements separate from the wheels, characterized in that the device comprises:
- a size of the at least one stability parameter can be determined by the control and regulation unit and is comparable to at least one predetermined limit value.
- the at least one stability parameter may in turn - just as described in connection with the method according to the invention - by the number a of wheels and supporting elements, on which the vehicle on Supported surface and / or the force-stability coefficient S F and / or the residual state moment M res t, Ka act as a function of the angle of rotation of the loading crane with respect to the currently relevant tilting edge K a .
- at least one warning signal can be generated by the control and regulation unit when the at least one predetermined limit value is exceeded or fallen short of, and / or at least one measure for restraining the at least one predetermined limit value can be controlled.
- the warning signal can be generated by the control and regulation unit, for example in the form of an electrical pulse sequence and then converted by means of warning lights and / or speakers in an optical and / or acoustic signal.
- the at least one measure for restoring the at least one predetermined limit value can be stored, for example, as a programmed course of action in the control and regulation unit.
- the action sequence is a stop process by which crane operation is stopped.
- the device has a rotation angle measuring device for detecting a rotation angle a of the loading crane about a vertical axis and / or an extended state measuring device for detecting an extended state of the support elements, wherein the measurement signals of the rotational angle and / or the extended state Measuring device (eg via corresponding signal lines or by wireless transmission) of the control unit can be fed.
- the support element measuring devices in the support elements and / or to arrange at the connection of the supporting elements with the Abstauerverbreiterung and / or at the connection of the Abstützverbreiterung with the crane base.
- the support forces provided by the wheel and support element measuring devices can be detected via the wheels and the support elements.
- the supporting forces F provided by the supporting elements in that the supporting element measuring devices are designed as load cells.
- the measurement of the supporting forces F for example via a measurement of Entfederungsdorf (the wheel suspensions) or the lengths L, the vibration damper (eg by means of cable length sensors) or via a measurement of the tire inner pressures.
- FIG. 1 shows a schematic representation of an exemplary embodiment of a vehicle on which a loading crane is mounted and which is relevant to the present invention
- 2 shows a model of the vehicle shown in FIG. 1, in which some of the parameters relevant to the stability monitoring are shown,
- Fig. 3a, 3b, 4a, 4b limit value representations for the minimum number of wheels
- Supporting elements via which the vehicle must be supported in different embodiments at least on the ground, in dependence on the angle of rotation ⁇ of the loading crane and the extended state of the supporting elements,
- Fig. 6 is a schematic representation of a possible
- Vibration damper of a wheel Vibration damper of a wheel.
- FIG. 1 shows schematically one of the examples of a vehicle 1 on which a loading crane 2 is mounted and whose stability can be monitored by means of the method according to the invention or the device according to the invention.
- the vehicle 1 via two front wheels 3a and four formed as a twin wheels rear wheels 3b and a laterally extendable Abstützverbreiterung 5 with two support elements 4 can be supported on the ground.
- the axles 6 of the vehicle 1 a part of the vehicle frame 9, a control and regulation unit 7 and the crane base 8 of the loading crane 2.
- the wheel, support element, rotation angle and extension state measuring devices are integrated or hidden by other vehicle components.
- FIG. 2 shows a model of the vehicle 1 shown in FIG. 1 in plan view.
- the support points on the ground black and white circles
- the position of the crane base 8 which at the same time defines the intersection of the vertical axis about which the loading crane 2 can be rotated, with the horizontal vehicle level, one of the in this state possible tilting edges K a and the distances /, ⁇ , « « of the support points (wheels 3a and 3b and support elements 4) to the Tilted edges K a drawn.
- the model further includes a definition of the angle of rotation of the loading crane 2 about the vertical axis. It should be noted that the wheels 3a and 3b are in reality not support points, but support surfaces. In the first nutrition, however, it was assumed that it was from the point of departure.
- FIGS. 3 a, 3 b, 4 a and 4 b show preferred limit values for the minimum number of wheels 3 a and 3 b and support elements 4 over which the vehicle 1 must be supported in different embodiments at least on the ground, depending on the angle of rotation ⁇ of the loading crane 2 and the Extended state of the support elements 4 shown.
- the reference numerals are representative of this group of figures only indicated in Fig. 3a.
- FIGS. 3a and 3b relate to the case where the vehicle 1 can be supported on both sides by a maximum of two front wheels 3a and two rear wheels 3b designed as twin wheels and two laterally extendable support extensions 5 with two support elements 4 each.
