Definitions
- the invention relates to a crane with a telescopic, in particular bendable Boom, a winch and arranged at the top of the boom pulley for a hoist rope on which a load-carrying means, for example a hook, is suspended, and with a control device for synchronizing the rotational movement of the winch with the telescopic or bending movements of the boom.
- the object of the invention is a generic crane with as few sensors and a suitable, as simple as possible synchronization method available put.
- the crane is a measuring device for Detecting the position or the rotational speed of the deflection roller has.
- a precise tracking of the winch then achieved when the control device has at least one electronic controller, preferably a PID controller.
- control device with a a controller connected input device for specifying setpoints to the controller exhibit.
- a particularly easy way to determine the rope movement on the pulley arises when the pulley several at regular intervals from one another Circular path arranged holes, wherein the center of the circular path on the Rotary axis of the guide roller is located, and the measuring device at least two preferably having inductive sensors for detecting the position of the holes. This can be done the succession of signal transitions to the direction of rotation, from the number of Pulses to the position and from the number of pulses per second to the Rotational speed of the guide roller can be closed.
- a method for synchronizing the rotational movement of a winch with the Telescopic or buckling movements of a boom of a crane are specified in for example, the distance of the lifting device from that of the load closest arranged deflection roller is kept substantially constant.
- Such a method is characterized in that the rope movement at the Deflection pulley at the tip of the boom by means of the measuring device in the direction and size is detected and passed as an actual value to the controller.
- the controller determines the controller in Dependency of the detected actual value, preferably taking into account a Setpoint, a manipulated variable for the control of the rotary motion of the winch to the Changing the distance of the lifting device from the pulley in a row To compensate for telescopic or a bending movement of the boom.
- the actual position of the pulley is detected by a counter depending on the direction and from this the actual speed by time differentiating the count calculated.
- the difference between the actual speed and the set speed which after a further embodiment of the invention the controller by means of a Input device can be specified, the control deviation is calculated and then a rotary valve controlling the rotary motion hydraulic valve as a manipulated variable switched on and optionally linearized the characteristic of the hydraulic valve.
- the crane 1 has a telescoping and bendable boom 2.
- the hoist rope 13 is on the winch 3 wound and along the boom 2 via a plurality of pulleys 4 to led to the top of the boom 2.
- a Load-receiving means 5 arranged for example in the form of a hook.
- the burden is with provided with the reference numeral 10.
- the boom 2 of the crane 1 can both Knickioloen a, a 'and push movements b, b' perform.
- the deflection roller 4 which is closest to the load, the movement of the hoist rope 13 in the direction and size detected by a measuring device 14.
- a controller 7 the, preferably taking into account setpoints, the controller 7 via a Input device 8 can be entered, and in a manipulated variable for a Hydraulic valve 9, by means of which the rotational movement of the cable winch 3 is controlled, transformed.
- the winch If the user specifies a set speed for the winch, it will open regulated proportional to this setpoint roller speed. It has been shown that all the rope length changing crane movements by appropriately tracking the Winch can then be easily compensated if the closest to Load arranged pulley is used for speed detection. Is a Changing the rope length desired by a setpoint, so the winch can a winch rotation speed corresponding to the target value, regardless of the the rest of the rope length changing crane movements - be regulated.
- Fig. 2 shows a section of a deflection roller 4 according to the invention, from which it can be seen that the deflection roller 4 has a plurality of holes 12 which are arranged at regular intervals, for example every 10 °, on a circular path K.
- the center M K of the circular path K lies on the axis of rotation D of the guide roller 4.
- the diameter d B of the holes 12 corresponds to half the distance A MB , the centers M B of the holes 12 from each other
- the measuring device two Sensors 11, 11 ' which may be formed, for example, as inductive proximity switches can, wherein, whenever a sensor 11 ', on the center of a bore 12th points, the second sensor 11, on the edge of a bore 12 shows. Because of these two shifted by 90 ° signals can from the succession of signals on the Direction of rotation, from the number of pulses to the position and from the number of pulses per second, the rotational speed of the pulley be closed.
- control device 6 comprises a controller 7, a measuring device 14 and optionally an input device 8.
- a target speed V SOLL for the winch 3 to the controller 7, for example via a joystick or via a radio remote control are specified.
- control deviation is calculated from the difference between the actual speed and the set speed and a winch 3 controlling hydraulic valve 9 is switched as a control variable before the characteristic of the hydraulic valve 9 is linearized.
- the subsequent rotational movement of the winch 3 in turn causes a rotational movement of the guide roller 4, the new actual position is detected in turn depending on the direction of the measuring device 14 in turn.
- the invention is not limited to the exemplary embodiments shown is limited.
- the preferably used PID controller could go through other electronic controllers are used.
- the essential feature of the invention is the detection of the rotational movement of the Pulley for the hoist rope at the tip of the boom in direction and size.
- a The basic idea of the invention thus represents the detection of the rotational movement of the deflection roller, which is closest to the load along the hoisting rope.
