when the correction mechanism 14 is moved to the intermediate position of the frame unit, the control cylinder 24 is activated, controlling the retraction of its piston rod, the lifting plate 23 being forced close to the mounting box 29; in this process, the movable rod 32 is in contact with the beam 15 and cannot move downwards, under the action of the two connecting rods 26, the two movable rods 32 move towards each other, the two limiting plates 53 are close to each other, the limiting plates 53 hook the two bailey pieces 11 of the frame unit, so that the two bailey pieces 11 are close to each other until the bottom plate of the beam 15 completely contacts the mounting frame 36, and the distance between the two bailey pieces 11 at least at the position hooked by the limiting plates 53 meets the design requirement;
in the process, before the movable rod 32 does not contact the cross beam 15, the two movable blocks 30 are close to the mounting box 29, when the movable rod 32 moves downwards, the two movable blocks 30 are far away from each other under the action of the transmission rod 31, the second telescopic rod 48 and the fourth telescopic rod 35 are lengthened simultaneously, the movable blocks 30 drive the correction blocks 52 and the correction rollers 28 to move along the length direction of the cross beam 15 together, and the correction rollers 28 roll relative to the bottom plate of the cross beam 15; after the correction rollers 28 on the two sides move, the parallelism degree of the two bailey pieces 11 is calibrated, and the larger the distance between the two moving blocks 30 is, the higher the calibration precision is;
in particular, during the descent of the two mobile bars 32, the presence of the alignment plates 25 prevents the two plates from tilting, the two alignment plates 25 always remain horizontal and the same in level;
s4, positioning; the correction mechanism 14 clamps the two bailey pieces 11 in the step S2 and the step S3 to be absolutely parallel, and the distance between the two is equal to the length of the diagonal brace 12; after the calibration in step S3 is completed, the control cylinder 24 is controlled to stop, so that the calibration mechanism 14 is kept in the state, and the calibration mechanism 14 in the state not only clamps the two bailey pieces 11 to enable the distance between the two bailey pieces to meet the requirement, but also keeps the two bailey pieces 11 absolutely parallel through the four calibration rollers 28;
s5, fastening; the diagonal braces 12 and the connecting beams 13 are installed and fixed between the two bailey pieces 11 by bolts, and the accurate frame unit is obtained after the correction mechanism 14 is removed from the bailey pieces 11; through the positioning step of S4, the relative position between the two bailey pieces 11 of the frame unit meets the design requirement, at the moment, the connecting beam 13 is clamped and supplied by using a mechanical arm, and the diagonal braces 12 and the connecting beam 13 can be installed by screwing bolts instead of manpower, so that the lap joint efficiency of the bailey frame is improved;
the correction mechanism 14 is removed from the frame unit, and as in the above-described principle, the movable bar 32 is first controlled by the control cylinder 24 to be raised, the movable block 30 is brought close to the mounting box 29, and then the drive motor 38 is activated to control removal of the correction mechanism 14 from one end of the frame unit.
S6, lapping; repeating the steps S1-S5 to obtain a plurality of frame units with required number, hanging the frame units to the target positions, connecting the frame units end to end in sequence, and fixing the frame units by utilizing the splice 17 and the bolt to match the splice holes 22.
