Embodiment Construction
[0042] Such as figure 1 As shown, the implementation steps of the automatic fine-tuning method for the swivel continuous beam used in the construction of the horizontal rotation method in this embodiment include:
[0043] 1) Determine the coordinates O(x 0 ,y 0 ,z 0 ), the origin of the attitude measurement coordinate system is the center of the spherical hinge, and the vertical and horizontal bridge directions are axis rotations; input A, B, C, and D design coordinates A (x a0 ,z a0 ), B(x b0 ,z b0 ), C(y c0 ,z c0 ), D(y d0 ,z d0 ), where A is the longitudinal attitude control point located on the upper turntable cap and the longitudinal axis of the beam body, B is the longitudinal attitude control point of the beam surface located on the beam surface and the longitudinal axis of the beam body, and C is the transverse direction of the beam surface located on the beam surface and the transverse axis of the beam body Attitude control point, D is the lateral attitude c...

The invention discloses a rotary continuous beam automatic fine adjusting method and system for horizontal rotation construction. Posture deviation of a beam body is calculated by sending measuring instructions according to measured data sent by a total station, displacement sensor data is compared with a theoretical displacement value calculated by a sensor, and threshold value of the deviation between the displacement sensor data and the theoretical displacement value is used a first control index of pushing of jacks arranged in the four directions of a rotary table cushion cap or cylinder receiving action of dynamic control. When the deviation between measured data of the sensor and a theoretical calculating displacement value meets the requirement of the threshold value, a repeated measuring instruction is sent to the total station by a controller, repeated measuring data is sent back by the total station, the deviation between repeated measuring coordinates of control points of two points and a designed coordinate are calculated again by a program, accurate adjustment stops if a requirement is met, the posture deviation of the beam body is calculated again if the requirement is not met, and pushing of the jacks is stared to adjust the posture again until the requirement is met. The rotary continuous beam automatic fine adjusting method and system for horizontal rotation construction has the advantages of being quick in response speed, high in execution efficiency, high in automation degree and convenient to construct.
Description
technical field [0001] The invention relates to the construction technology of a continuous girder with a horizontal rotation method for bridge engineering, in particular to an automatic fine adjustment method and system for a continuous beam with a rotary body used in the construction of a horizontal rotation method. Background technique [0002] After the continuous beam is rotated by the horizontal rotation method, the posture of the beam body needs to be adjusted precisely to ensure the line shape of the beam body and the closure. At present, the procedures for precise adjustment of beam posture are all done manually, which has disadvantages such as poor precision control, slow response speed, and low work efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention: Aiming at the above-mentioned problems of the prior art, provide an automatic fine-tuning method for the continuous beam of the rotating body used in the const...
