The invention relates to a deflection calibration tower crane and a deflection calibration method of a lifting hook of the deflection calibration tower crane. The crane comprises a hanging mechanism,and a movable pulley device of the hanging mechanism is connected with a movable trolley through a first rope section; the lifting hook is connected with the movable pulley device through a second rope section; a measuring and controlling unit is used for controlling and measuring the rotating angle of a tower arm and the sliding distance of the movable trolley; a deflection measuring device is arranged at the bottom of the movable pulley device and used for measuring the deflection data of the lifting hook; and a processing unit is in communication connection with the measuring and controlling unit and the deflection measuring device, and the processing unit is used for controlling the tower arm to rotate and the movable trolley to slide so as to counteract the swing of the lifting hook.According to the deflection calibration tower crane and the deflection calibration method, the swing of the movable pulley device and the lifting hook can be subjected to real-time anti-swing adjustment.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to a deflection calibration method for a deflection calibration tower crane and a hook thereof. 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 in the working position, so as to accurately lift the goods. However, in the actual working process, since the rope section connecting the hook is flexible, the rope section is easily affected by the wind and swings during high-altitude operations, which in turn drives the hook to move and sway, making the hook unable to accurately lift the cargo. rise. On the other hand, after the hook lifts the goods, when the rope segment and the suspension hook swing sharply, the lifted goods may fall from the suspension hook, which may easily cause ...
