[0030] Working principle: First, assemble the positioning ring 21 on the casting template 1, rotate the second movable ring 41 that is rotatably connected to the positioning ring 21 by the second bearing 42, and the second ring gear 43 that is fixedly connected to the second movable ring 41 through the connecting rod 49 rotates inside the positioning ring 21, and the second transmission gear 44 fixed on the disc-shaped shaft 45 is engaged with the second ring gear 43, thereby causing the sliding rod 46 that is fixedly connected to the disc-shaped shaft 45 to rotate together, and the connecting bolt 48 that is slidably connected to the sliding rod 46 is also threadedly connected to the fixing nut 47, so that After the disc-shaped shaft 45 drives the sliding rod 46 to rotate, the connecting bolt 48 can be screwed out from the inside of the positioning ring 21 and then screwed into the inside of the casting template 1 to fix the positioning ring 21 on the casting template 1; then the first movable ring 33 is pulled to create a gap between the first movable ring 33 and the stop ring 36 fixed on the casting template 1, and then the first movable ring 33 is rotated, and the connecting rod 311 fixed on the first movable ring 33 is slidably connected with the connecting ring 34, and the connecting ring 34 is fixed on the first ring gear 32. The first ring gear 32 A first bearing 35 is also used to rotate with the positioning ring 21, and the first ring gear 32 can rotate as the first movable ring 33 rotates, wherein the first ring gear 32 is engaged with the first transmission gear 31, and the first connecting shaft 37 is fixed on the first transmission gear 31. The main bevel gear 38 at the end of the first connecting shaft 37 is engaged with the auxiliary bevel gear 39, and the auxiliary bevel gear 39 is fixedly connected to the screw 24 using the second connecting shaft 310. Therefore, the screw 24 can rotate as the first transmission gear 31 rotates, and the screw 24 is rotated. The threaded L-shaped slide 23 can drive the baffle 22 to slide on the positioning ring 21, and the first ring gear 32 can be engaged with multiple first transmission gears 31 at the same time, so that the distance between the multiple baffles 22 can be changed, so that the space between the baffles 22 can accommodate the steel cage. Because the multiple baffles 22 can slide synchronously, the center of the steel cage can coincide with the center of the casting formwork 1 below it, so that the steel cage can be placed inside the casting formwork 1, ensuring the quality of the subsequent casting of the prefabricated pile foundation and meeting the subsequent construction requirements of the wharf.
