Definitions

  • the present invention is directed to a system for measuring a horizontal deflection of a load-carrying means in relation to a position of a trolley, wherein the load-receiving means is arranged suspended on a plurality of supporting cables on the trolley, and to a method for measuring a horizontal deflection of a load-receiving means in Relation to a position of a trolley, wherein the load-receiving means is arranged on a plurality of support cables hanging on the trolley.
  • Pendulum damping devices from the company CePLuS GmbH in Magdeburg are known, which use high-performance cameras with microprocessors to measure the horizontal deflection of the load-handling device. These high-performance cameras are mounted on a trolley and measure the load movements to adjust the speed of the trolley while driving so that no unwanted vibrations of the loads occur.
  • reflectors are mounted on the load handler.
  • the camera mounted on the trolley is down, i. directed towards the load-carrying means and determines the position of the reflector relative to the trolley. From these position data of the reflector, the deflection of the lifting device is calculated.
  • a system for measuring a horizontal deflection of a lifting device in relation to a position of a crane trolley, wherein the load receiving means is arranged suspended on a plurality of parallel support cables on the trolley, at least two rope length sensors are provided which are operative with a data processing means, preferably a processor are connected, wherein the separate ropes of the at least two rope length sensors are not arranged parallel in Katzfahrtraum between trolley and load receiving means, and wherein a data processing means connected to the computing unit determines the horizontal deflection of the load receiving means in relation to the position of the trolley over the length of the respective ropes of Seillygeber ,
  • the inventive system is based on the finding that when using at least two rope length sensors, which are each arranged on the trolley and / or each on the load receiving means, the horizontal deflection of the lifting device causes a shortening of the rope length at least one of the rope length sensor, while this horizontal deflection in which at least one other rope length sensor causes an extension of the rope length.
  • the at least two rope length sensors are advantageously arranged on the crane trolley or on the load receiving means in such a way that the two ropes of the at least two rope length sensors intersect.
  • Such a crossing of the at least two ropes is achieved in that one of the at least two rope length sensors is arranged in a front region of the crane trolley or load handling device, while the other of the at least two rope length sensors is arranged in a rear region of the load suspension device or crane trolley and the anchoring point the respective ropes is biased diagonally from the respective front area into the respective rear area and from the trolley to the load receiving means.
  • this type of bracing it is irrelevant whether the rope length sensor is arranged on the same side of the trolley or the load-carrying means, as long as an at least spatial crossover can be ensured.
  • bracing of at least two ropes and the rope length measurement of the rope length sensor is determined by applying simple trigonometric relationships, which are deposited in an algorithm in a computing unit, the horizontal deflection of the lifting device exactly.
  • the deflection angle is required, is determined by a second mathematical step, also using simple trigonometric relationships, the deflection angle, which is spanned between the vertical and the support cables. The deflection angle can then form an input variable for the subsequent calculations of the movement system crane / load receiving means.
  • the two cables are not crossed, but form a spatial "V", wherein the anchoring points of the respective ropes is advantageously arranged at the apex of this spatial "V".
  • simple trigonometric calculations are performed in the same way.
  • FIG. 1 a system according to the invention is shown, consisting of a trolley 1, which is driven by a motor M for transport on the rail 11.
  • the power supply of the motor M is not shown.
  • the control of the motor M is made via a control unit S, which is operatively connected to the motor M, but need not necessarily be arranged on the trolley.
  • a data processing means preferably a processor with a computing unit in which appropriate mathematical algorithms are stored.
  • two rope length sensors 3, 4 are arranged on the crane rake 1, the ropes 8, 9 are stretched diagonally downwards in the direction of the load-receiving means 2 and fixed there in an anchoring point 5 and 6 respectively.
  • the length of the ropes 8 and 9 is in the rest position of FIG. 1 essentially the same, because, due to gravity, the load-carrying means 2 vertically below the trolley on the support cables 10a and 10b, as well as to the support cables 10c and 10d, not shown hangs.
  • the length of the support cables 10a to 10d is also controlled by the motor M or via a separate drive.
  • rope length encoders from TR Electronic GmbH are used which have an absolute or incremental encoder.
  • the carrying cables 10a to 10d are deflected counter to the direction of movement due to the inertia by a specific value A which corresponds to a specific angle ⁇ .
  • A which corresponds to a specific angle ⁇ .
  • FIG. 2 the position of movement of the system according to the invention is shown at a certain time in which the trolley has reached a speed v.
  • the arithmetic unit After the processing of mathematical algorithms, the arithmetic unit indicates the deflection A as a path of the absolute deflection, or optionally the angle ⁇ as the output value. This value is then entered into the control system for controlling the motor M and further processed there accordingly, for example, for pendulum suppression of the lifting device.
