Door crane brake swing warning system and method for segment hoisting of subway shield tunnel

Abstract

The invention belongs to the field of hoisting operation safety control, and discloses a door crane brake swing early warning system and method for segment hoisting of a subway shield tunnel, wherein the early warning system includes a hoisting data acquisition module, a data analysis and prediction module, and a segment swing early warning module The hoisting data acquisition module is used to collect the spatial information of the subway segment in the hoisting process in the downhole in real time; the data analysis and prediction module reasonably predicts the future hoisting trajectory of the subway segment through the above-mentioned collected data; the segment swing early warning module is based on The hoisting prediction trajectory calculates and judges the possible swing size of the subway segment and outputs the corresponding early warning signal. The invention predicts the hoisting trajectory based on the composite model of data drive and motion analysis, and uses reasonable and accurate predicted trajectory to carry out pre-warning control on the unsafe swing of the subway segment during the deceleration and braking phase of hoisting, and optimizes the safety control of the hoisting process of the subway segment , Actively avoid subway segment hoisting accidents.

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
