In the structure, before the rotary support is rotated, the locking piece is loosened, then the rotary support is rotated by 180 degrees manually, and the direction of the rotary mandrel is adjusted, so that the paving direction of the equipment is adjusted; after the rotation is completed, the locking piece is locked again to prevent the rotary support from rotating again.

In the four embodiments, as compared with embodiments 1 to 4, the cloth can be spread in both directions even when the cloth spreading vehicle 2000 moves back and forth along the rail 1000.

Examples 9 to 12

Referring to fig. 1 to 3 and 5, the four embodiments also provide a blade girder mold laying device, which has the same specific structure as embodiments 1 to 4, respectively, except that the yardage roll mounting mechanism 4100 includes a mounting seat provided on the laying cart 2000, and two inflatable shafts rotatably provided at both ends of the mounting seat. The rotation directions of the yardage rolls S of the two air expansion shafts are opposite when the yardage is paved; the expansion of the air expansion shaft can be controlled by increasing the amount of compressed air in the air expansion shaft, so that the expansion and fixation of the yardage roll are realized.

The air expansion shafts in the four embodiments are only required to be of a conventional structure.

Compared with the embodiments 1 to 4, the two embodiments provide another cloth roll mounting structure, and can also realize corresponding functions.
