Gantry crane brake swing early warning system and method for subway shield tunnel segment hoisting

Abstract

The invention belongs to the field of hoisting operation safety control, and discloses a gantry crane brake swing early warning system and method for subway shield tunnel segment hoisting. The early warning system comprises a hoisting data acquisition module, a data analysis and prediction module and a segment swing early warning module, wherein the hoisting data acquisition module is used for acquiring spatial information of subway segments in the underground hoisting process in real time; the data analysis and prediction module reasonably predicts the future hoisting track of the subway segments through the acquired data; and the segment swing early warning module calculates and judges the possible swing size of the subway segments according to the hoisting prediction track and outputs acorresponding early warning signal. Hoisting track prediction is performed based on the composite model of data driving and motion analysis so that early warning control can be performed on unsafe swing of the subway segments in the hoisting deceleration brake stage through the reasonable and accurate prediction track, safety control of the underground hoisting process of the subway segments canbe optimized and the subway segment hoisting accident can be actively avoided.

Description

technical field [0001] The invention belongs to the field of hoisting operation safety control, and relates to a door crane swing warning system and method for the hoisting of subway shield tunnel segments, more specifically, to a method for predicting the swing of segment hoisting brakes during the hoisting process of subway segments and early warning mechanism. Background technique [0002] With the rapid development of economy and society, people's demand for transportation is constantly increasing, and the construction scale of urban rail transit is also expanding. As an important component of urban rail transit, subway segments are facing various problems and threats during the hoisting operation. During the hoisting operation of the subway segment, due to the underactuated characteristics of the gantry crane and the influence of the external environment, when the gantry crane brakes and decelerates near the entrance of the downhole, the subway segment will easily swing...

AI Technical Summary

Problems solved by technology

During the hoisting operation of the subway segment, due to the underactuated characteristics of the gantry crane and the influence of the external environment, when the gantry crane car brakes and decelerates near the entrance of the downhole, the subway segment will easily swing, which will have a great impact on the hoisting safety and hoisting efficiency. earth threat

Under normal circumstances, the swing of the subway segment during the braking deceleration phase is usually suppressed and eliminated by the driver's early deceleration based on operating experience and personal subjective judgment. However, this type of method has high requirements for the driver's operation and is not universal. sex, there is still a certain risk
