Real-time security monitoring system for bridge girder erection machine

Abstract

The invention discloses a real-time security monitoring system for a bridge girder erection machine. The real-time security monitoring system comprises a data acquisition module connected to a monitoring host; the monitoring host is connected to an alarm module, and the monitoring host sends received data to a remote service center via a first wireless communication module; and the remote servicecenter is connected to a video monitoring module for acquiring video information of a real-time working process of the bridge girder erection machine through a second wireless communication module. The monitoring host monitors the lifting capacity of the bridge girder erection machine, the inclination of a main beam, longitudinal and lateral displacement of an overhead travelling crane, the lifting height and the descending depth of a lifting system, longitudinal displacement and the speed of the bridge girder erection machine, longitudinal displacement of a beam guiding machine, the supporting leg pressure, the supporting leg perpendicularity, the wind speed and position information in real time through the data acquisition module, sends the received data and the working process video information to the remote service center through the wireless communication modules, and can timely issue a warning command when a dangerous situation is discovered, and can instruct construction workersto stop operations so as to prevent serious safety accidents.

Description

technical field [0001] The invention relates to the field of operation management of bridge erecting machines for railway construction, in particular to a real-time safety monitoring system for bridge erecting machines. Background technique [0002] With the promulgation and implementation of "China Railway "Eleventh Five-Year" Plan" and "Medium and Long-term Railway Network Planning", it is estimated that by 2020 the national railway mileage planning target will reach more than 120,000Km. The rapid development of my country's high-speed railway construction also provides a broader application platform for bridge erecting machines. The bridge erecting machine is a special construction machinery equipment used to hoist and erect prefabricated beams on prefabricated bridge piers, which is essentially a type of crane. The lifting weight of the currently used bridge erecting machine can reach more than 900T. If there is a slight carelessness during the erection process, a safet...

AI Technical Summary

Problems solved by technology

The lifting weight of the currently used bridge erecting machine can reach more than 900T. If there is a slight carelessness during the erection process, a safety accident will occur and cause huge economic losses. In view of the special operating conditions of the equipment, the equipment must be inspected Corresponding security monitoring

However, in the prior art, the bridge erecting machine does not have a complete monitoring system, so that the project management personnel cannot obtain the real-time operation data of the bridge erecting machine in time, so that the management personnel cannot grasp the progress and quality of the project in time, and cannot timely monitor the construction process. Early warning of possible dangerous situations in the

At the same time, during the entire construction process, the operating data of all bridge erecting machines is opaque, and there is a risk of artificially modifying the data, which will cause difficulties in the investigation of the cause of the accident and the identification of responsibilities after the accident.
