Intelligent girder segment matching installation control system

Abstract

The invention discloses an intelligent girder segment matching installation control system. The intelligent girder segment matching installation control system comprises an angle sensor and a central control unit, wherein the angle sensor is arranged at the front end of a girder segment to be installed and is used for collecting the data of the included angle between the girder segment to be installed and an installed girder segment; the central control unit is in communication connection with the angle sensor so as to receive the included angle data of the girder segment to be installed and convert the included angle data into altitude data xi of an installation point of the angle sensor; and the central control unit judges whether the height difference of the altitude data xi of the installation point and the theoretical installation height h1 of the girder segment to be installed at the position of the installation point is larger than 2 mm or not, and if yes, the central control unit sends a starting signal to a bridge floor crane. According to the intelligent girder segment matching installation control system, by setting the position relation between the angle sensor and the girder segment and measuring the relative included angle between the girder segments, errors caused by steel girder vibration is avoided, the procedures of the whole girder segment matching process are simplified, informationized and intelligentialized, the control precision is fundamentally guaranteed, and meanwhile the labor cost is also reduced.

Description

technical field [0001] The invention relates to the technical field of bridge construction intelligent control. More specifically, the present invention relates to an intelligent beam section matching installation control system. Background technique [0002] Most modern steel box girder girder section assembly construction control technologies use geometric control methods, so the matching installation of steel box girders is the top priority of control. If the matching installation control is not in place, it will cause the accumulation of main girder linear errors. In subsequent construction measures It is difficult to rectify the deviation, and it also violates the control principle of the geometric control method. In the past, the matching installation control of steel beams firstly measured the monitoring and measuring points through the level instrument, and then fed back to the on-site monitoring personnel. After the monitoring personnel analyzed and proposed the ad...
