Safety monitoring system for bridge girder erection machine

Abstract

The invention relates to a safety monitoring system for a bridge girder erection machine. The safety monitoring system comprises a detection module, a data acquisition module, a data encryption and compression module, a control module, a wireless communication module and a monitoring host. The detection module comprises a hoisting weight sensor arranged on a winch of the bridge girder erection machine and used for detecting hoisting weight of the winch. The data acquisition module is electrically connected with the hoisting weight sensor and the control module respectively and transmits a weight signal of the hoisting weight sensor to the control module. The data encryption and compression module is electrically connected with the control module and used for compressing and encrypting the weight signal. The control module transmits the compressed and encrypted weight signal to the monitoring host through the wireless communication module. The monitoring host comprises a decompression module and a data analysis module, wherein the decompression module decompresses the compressed and encrypted weight signal, and the data analysis module performs judgment on the weight signal and determines whether weight goes beyond the set value.

Description

technical field [0001] The invention relates to a safety monitoring system, in particular to a safety monitoring system of a bridge erecting machine. Background technique [0002] The bridge erecting machine is the equipment that places the prefabricated girders on the prefabricated bridge piers. Bridge erecting machines fall into the category of cranes because their main function is to lift beams, transport them into position and then lower them down. Present bridging machine mainly comprises cart, crane and hoist; Described cart bottom is provided with front support leg, middle support leg, rear support leg, and this cart is provided with left girder and right girder. The crown block is arranged above the left girder and the right girder, and can move along the left girder and the right girder. The winch is set on the crane.

[0003] Since there is no perfect monitoring system in the prior art, if there is a failure during the transportation of the beam, it will cause serious personal safety to the staff

Especially in some construction sites with complex environments, the construction is very difficult. Once an accident occurs, it will affect the construction progress and quality of the entire project, and may cause casualties
