Embodiment

[0039]The purpose of the present invention is to disclose a 1300t-class beam-carrying vehicle that adopts grouping and modular design, and specifically relates to a PID loop-based synchronous control system and method for multi-vehicle groups of a beam-carrying car. The 1300t-class beam-carrying Rectangular distribution structure, the power system is distributed on four single cars, No. Ⅰ and No. Ⅳ cars are connected by the front load-bearing beam to form the front group, and No. Ⅱ and Ⅲ cars are connected by the rear load-bearing beam to form the rear group. The rotatable driver's cab, each vehicle group is equipped with a wireless remote control device, and the "soft-rigid" connection between the vehicle groups is realized through the PID closed-loop control system. The 1300t-class beam transport vehicle is mainly composed of front car body, rear car body, front traveling wheel set and steering mechanism, rear traveling wheel set and steering mechanism, front load beam, rear ...

Abstract

The invention relates to a synchro-control system and method for multiple wagons, belongs to the technical field of bridge construction, and in particular relates to a PID loop-based synchro-control system and method for multiple wagons of a girder transporting vehicle. The system and method integrate a corner sensor device, a pull wire sensor device, a PLC control system as well as actuating components such as a pump, a motor and an oil cylinder for participating in control together, thereby improving the synchro-control effect. The invention provides a new angle measuring device, the rotation condition of an independent flat wagon is judged by measuring the angle of rotation of a spherical hinge, thereby providing more precise angle reference data for synchro-control. The invention also provides a new pull wire sensor device, the position postures of two wagons can be accurately judged by the change of the pull wire values of the two ends of the two wagons, and further the distance between the two wagons can be judged, thereby providing more precise distance reference data for synchro-control.

Description

technical field [0001] The invention relates to a multi-vehicle synchronous control system and method, belonging to the technical field of bridge construction, in particular to a PID loop-based multi-vehicle synchronous control system and method for beam transport vehicles. Background technique [0002] With the continuous progress of bridge construction technology, in order to ensure project quality, construction safety and construction period, more and more domestic expressway bridges, especially cross-sea bridges, adopt "box girder whole hole prefabrication, cross-line lifting machine to lift the bridge, transport The construction scheme of transporting on the girder and vehicle girder, and erecting the bridge erecting machine hole by hole". The prestressed concrete box girder used in the sea-crossing bridge generally has a span of 40m or 50m, and the weight is mostly 1200-1600 tons, which is much larger than the 900-ton box girder of the high-speed railway. In order to ...
