Embodiment approach

[0026] According to an implementation manner, the real-time vertical tilt variation can be calculated as follows:

[0027]

[0028] in, is the real-time vertical tilt variation of n epochs at the head end of the tower arm, is the instantaneous vertical sway velocity of the head end of the tower arm in the i-th epoch, ΔT i is the data sampling interval of the i-th epoch of the GNSS monitoring station, f i Be the data sampling rate of the i-th epoch of the GNSS monitoring station, determined by the performance of the GNSS monitoring station, f i = 1Hz ~ 50Hz.

[0029] According to an implementation manner, the predetermined value can be calculated as follows:

[0030]

[0031] in, is the predetermined value, L B is the length of the tower arm, K is the verticality coefficient of the tower crane,

[0032] According to this embodiment, the sampling rate can be changed according to the speed change, which can reflect the real-time vertical tilt variation better ...

Abstract

The invention discloses a construction site tower crane collapse emergency disposal system. The tower crane comprises a tower footing, a moving trolley, a tower body and a tower arm. The constructionsite tower crane collapse emergency disposal system comprises a collapse confirmation device used for confirming that collapse danger exists; a hoisted object conveying device used for conveying the hoisted object to the position above the object throwing area; and a hoisted object throwing device used for throwing the hoisted object into the object throwing area.

Description

technical field [0001] The invention relates to an emergency treatment system for the collapse of a tower crane on a construction site. Background technique [0002] Occasional collapse accidents of tower cranes on the construction site occur. Once a collapse accident occurs, it will cause large property losses or casualties. It is very important to carry out emergency treatment when the tower cranes on the construction site collapse. Attention is not enough. Contents of the invention [0003] In view of the above circumstances, the present invention proposes an emergency treatment system for tower crane collapse at a construction site, which is used to alleviate or eliminate one or more shortcomings in the prior art, and at least provide a beneficial option. [0004] In order to achieve the above objectives, one aspect of the present invention discloses a construction site tower crane collapse emergency treatment system, the construction site tower crane includes a tower...
