A deviation correction monitoring system for a beam transport vehicle

Abstract

The invention belongs to the field of railway construction, and provides a rectification monitoring system of a beam transport vehicle. The rectification monitoring system of the beam transport vehicle comprises a plurality of ultrasonic sensor pairs, a lower machine, an upper machine, a human-machine interaction unit and a first alarm. Each ultrasonic sensor pair comprises two ultrasonic sensorssymmetrically arranged on the left and right sides of the beam transport vehicle. The ultrasonic sensor pairs are used for measuring the distances between the beam transport vehicle and rebar fabrications on the left and right sides during the advancing process. The lower machine is internally provided with a multi-channel data acquisition and conversion module and an angle steering controller. Signal output ends of the ultrasonic sensor pairs are connected with the upper computer through the multi-channel data acquisition and conversion module. The upper computer is used for judging whether the running of the beam transport vehicle is shifted according to the detection signals of the plurality of ultrasonic sensor pairs and giving out an alarm through the first alarm, and meanwhile carrying out rectification control through the angle steering controller. The rectification monitoring system of the beam transport vehicle guarantees the safety during the transportation operation processof box girders and can be widely applied to the field of railway construction.

Description

technical field [0001] The invention belongs to the technical field of railway construction, and in particular relates to a deviation correction monitoring system for beam transport vehicles. Background technique [0002] With the rapid development of China's high-speed railway construction, the construction of railway passenger dedicated lines has become a major trend in the development of China's railways. Looking at the high-speed railway lines that have been built or are under construction in China and the world, most of the lines using viaducts account for the total length of the lines. More than half of the construction of the viaduct, half of the construction of the viaduct adopts a double-line full-hole box girder structure. The box girder’s self-weight is generally about 900t. The use of prefabricated frame construction methods has obvious limitations in ensuring quality and construction period. Therefore, the railway box girder erection lifting frame equipment Howe...
