Abstract

The invention discloses a device for calibrating perpendicularity and rectifying deviation of a tower crane and a construction method thereof. The device comprises a laser calibration device and a hydraulic deviation rectifying device, wherein the laser calibration device comprises a laser emitter, a laser reflector and a laser receiver; the laser emitter is mounted in a center hole in the upper surface of a base bracket; a power supply adapter is mounted in the base bracket; the laser reflector comprises a reflection lens, a lens framework and a framework transverse frame. The device has the advantages that the device is high in practicability and is safe and reliable, the problem of deviation of a standard section of the tower crane is solved by a deviation rectifier, the problem of calibration of the perpendicularity of the tower crane is solved by the laser calibrator, the working efficiency is improved, and the potential safety hazard is eliminated.

Description

technical field [0001] The invention relates to a building construction auxiliary device and a construction method, more specifically, to a tower crane verticality calibration and deviation correction device and a construction method thereof. Background technique [0002] Tower cranes are widely used in the field of construction due to the advantage of vertical transportation height. However, tower crane collapse accidents have occurred frequently in recent years. The reason is that most of them are caused by the instability of the vertical deviation of the tower crane, and the main reason for the vertical deviation is the lack of correction and calibration means in the installation and maintenance, so that there are some east-west deviations, some north-south deviations, and some The twisted shape exceeds the value specified in the standard specification. In the prior art, an attachment device is usually added to reduce the degree of harm of the deviation. The function of ...
