The invention relates to a deflection calibration method for a tower crane and its hook. The crane includes a hanging mechanism, and a movable pulley device of the hanging mechanism is connected to a moving trolley through a first rope segment; the hook is passed through a second rope segment. It is connected with the movable pulley device; the measurement and control unit is used to control and measure the rotation angle of the tower arm and the sliding distance of the mobile trolley; the deflection measuring device is set at the bottom of the movable pulley device to measure the deflection data of the hook; the processing unit is connected with the measurement and control unit and The yaw measuring device is connected in communication to control the rotation of the tower arm and the sliding of the mobile trolley to counteract the sway of the hook. The invention can carry out real-time anti-sway adjustment to the swing of the movable pulley device and the hook.
Description
Technical field [0001] The invention relates to the technical field of building construction, in particular to a yaw calibration method for a yaw calibration tower crane and its hook. Background technique [0002] During the operation of the tower crane, in order to accurately complete the lifting operation, it is necessary to ensure that the hook can accurately move to the working position and maintain a stable posture at the working position to facilitate accurate lifting of the goods. However, in the actual work process, because the rope segment connecting the hook is flexible, the rope segment is susceptible to the influence of wind to swing during high-altitude operations, which drives the hook to move and sway, making the hook unable to accurately lift the cargo. Up. On the other hand, when the hook lifts the cargo, when the rope segment and the hook swing greatly, the lifted cargo may fall off the hook, which may easily cause safety accidents. At the same time, when the ...
