The invention relates to a deflection measuring device for crane GNSS detection. A crane comprises a support which is provided with a tower arm and a moving trolley, a hanging mechanism which comprises a first rope section, a second rope section, a movable pulley device and a lifting hook, a measurement and control unit, a GNSS detection end and a deflection measuring device body, the movable pulley device is connected with the moving trolley, the first rope section drives the movable pulley device to lift, the lifting hook is connected with the movable pulley device through the second rope section, the measurement and control unit is used for measuring the rotating azimuth angle of the tower arm and the sliding distance of the moving trolley and controlling the tower arm to rotate and themoving trolley to slide, the GNSS detection end is arranged at the top of the movable pulley device and is in communication connection with a GNSS base station, the deflection measuring device body is arranged at the bottom of the movable pulley device and used for measuring deflection data of the lifting hook, the deflection measuring device body comprises an Invar round bar code digital levelness disc and a laser signal transmitter, the Invar round bar code digital levelness disc is arranged at the bottom of the movable pulley device, and the laser signal transmitter is arranged on the second rope section.
Description
[0001] This application is a divisional application with an application date of June 12, 2018, an application number of 201810602081.0, and an invention title of "A deflection calibration method for a deflection calibration tower crane and its hook". technical field [0002] 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 [0003] 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 s...
