Background
Most of the construction engineering construction needs to use a tower crane for vertical transportation, and the tower crane is used as a large-scale machine, so that the safety measures of the tower crane are effectively guaranteed. The periodic measurement of the perpendicularity of the tower crane is one of the safety guarantee measures. The measurement of the tower crane perpendicularity is usually carried out by using a pendant or a theodolite. The former has harsh requirements on weather, and especially when the tower crane is high in height, the wind power greatly influences the measurement precision and the measurement efficiency; the latter measures more accurately, but needs the manual hand tape measure to stand under the tower crane and cooperate the observation of theodolite.
At present, the verticality of the tower crane is mostly measured by using a theodolite, a manual handheld tape measure is needed to be stood under the tower crane for matching, and if no manual matching is available, observers can estimate the deflection distance of the tower crane by virtue of experience. And the tower crane verticality detection needs to measure the skewness in two directions, so that an observer is required to carry an instrument and select two observation points to successively erect the instrument twice. This approach requires specialized measurement personnel; the error is large, and the measuring result cannot be accurate; the observation point has certain distance requirement, and can not be too close to the tower crane, otherwise the observation point can be limited by too large elevation angle of an observation mirror of an instrument and can not be observed; moreover, observation personnel are required to carry the instrument for multiple times of erection, and the observation process is complicated.
Therefore, the tower crane verticality detection tool is provided to solve the problems.
