Embodiment Construction

[0016] Two coordinate systems are set, one coordinate system origin O is the center point of the fixed section of the tower body on the ground, the positive direction of the coordinate axis x is the north direction of the ground, the positive direction of the coordinate axis y is the west direction of the ground, and the positive direction of the coordinate axis z is perpendicular to the ground upward; the origin Ot of the other coordinate system is the intersection point of the slewing bearing slewing plane at the top of the tower body and the straight line passing through point O and perpendicular to the ground. The positive direction of the coordinate axis Zt is perpendicular to the ground and upward, and the positive direction of the coordinate axis Yt is perpendicular to the boom axis and the Xt and Zt axes conform to the right-handed spiral rule. Such as figure 1 shown. OOt is perpendicular to the ground.

[0017] On the OtXtYt plane in the OtXtYtZt coordinate system, ...

Abstract

The invention relates to a real-time measuring method and a real-time measuring device for the lateral perpendicularity of a tower crane steel structure by a tilt angle sensor, in particular to a method and a method for realizing the measurement of the lateral perpendicularity of a tower body through measuring the component of the top end of the tower body on the side of the tower body. The measurement, display, alarm and recording functions are achieved through the real-time measuring device. The measuring method and the measuring device have the advantages that the lateral perpendicularity of the tower crane steel structure is accurately measured in a real-time manner by a signal acquisition technique, a signal processing technique, an electronic circuit technique and the like, the phenomenon of inaccurate measurement of the lateral perpendicularity of the tower crane steel structure can be reduced, the phenomenon of too high lateral perpendicularity of the tower crane steel structure is prevented, and the accident rate is reduced. The device is convenient to use, is not influenced by the environment, and has a good popularization and application value.

Description

technical field [0001] The invention relates to a real-time measurement method and device for detecting the lateral verticality of a steel structure of a tower crane. technical background [0002] With the development of the construction industry, there are more and more high-rise buildings, and tower cranes are widely used in construction sites as a kind of high-altitude operation equipment. However, due to the high center of gravity of the tower crane and the need to start and stop to complete the transportation of heavy objects during the work process, the tower crane is more dangerous than other lifting equipment during the work process. [0003] In order to ensure the normal and safe operation of the tower crane, the state has issued relevant regulations. Among them, the regulations on the lateral verticality of the tower crane in GB5031-2008T are: the lateral verticality of the tower crane is not greater than 4‰. [0004] At present, the measurement of the lateral ver...
