Description
Technical Field
The utility model relates to the field of bridge segment prefabrication construction, in particular to a segment beam short-line method prefabrication system matched with a trolley for automatic adjustment.
Background
In the prefabrication construction of the segmental beam by the short line method, each segment needs to be prefabricated in a matching way with the previous segment, and the overall line type of the bridge is controlled by adjusting the space attitude of the previous segment (matching beam).
The adjustment mode that present matching beam usually adopted does:
1) a surveyor measures monitoring points on a beam surface on a measuring tower through a total station, and compares and converts the monitoring points with bridge linear target data to give adjustment quantities of a first monitoring point in x, y and z directions;
2) a worker sequentially operates the vertical oil cylinder, the horizontal oil cylinder and the longitudinal oil cylinder on the matching trolley to perform matching adjustment according to the adjustment amount of the first monitoring point and experience;
3) a measurer repeatedly measures the adjustment quantity data of the first monitoring point and tells workers operating the matching trolley to adjust until the first monitoring point is adjusted in place;
4) the measurer measures a second monitoring point and gives the adjustment quantity of the second monitoring point in three directions;
5) a worker operates vertical, horizontal, rotary and longitudinal oil cylinders on the matched trolley in sequence according to experience to adjust a second monitoring point;
6) the surveyor and the worker respectively repeat the measurement and the adjustment in the same way until the second monitoring point is adjusted in place;
7) repeating the steps, and continuously adjusting other monitoring points behind until the adjustment of all six monitoring points is completed;
since the monitoring points on the matching beam surface are associated with each other, when the position of the next monitoring point is adjusted, the position of the previously positioned monitoring point is changed, so that the adjustment is started from the first point, the next cycle is continued, and the target is continuously approached until all the points are adjusted to the target range.
In the process of operating and matching the trolley by workers, because the extension amount of the oil cylinder on the trolley and the displacement amount of the monitoring point of the beam surface have no direct relation, the adjustment amount of the monitoring point on the beam surface cannot be directly converted into the action amount of the oil cylinder, and the adjustment amount completely depends on the experience of the workers.

Therefore, the existing problems can be solved by a mode which can save manpower, is simple and convenient to operate, can realize quick matching of segments and has high safety.
