Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5This utility model provides an embodiment of a concrete pouring formwork positioning auxiliary mechanism, comprising a positioning ring 1 and a connecting rod 2. A transmission chamber 3 is fixedly installed on the upper end of the positioning ring 1. A gear ring 4 is provided on the inner side of the transmission chamber 3, and a bevel gear 5 is provided on the side of the gear ring 4. An adjusting knob 6 is provided on the outer side of the transmission chamber 3. A limiting plate 7 is fixedly installed on the surface of the transmission chamber 3. A lead screw 8 is provided at the lower end of the limiting plate 7. A driving plate 9 is provided on the outer side of the lead screw 8. A clamping plate 10 is fixedly installed at the end of the driving plate 9. A knob 11 is provided at the upper end of the transmission chamber 3. A lead screw 12 is fixedly installed at the lower end of the knob 11. A locking block 13 is provided at the lower end of 12, a threaded hole 14 is provided at the lower end of the positioning ring 1, and a connecting sleeve 15 is provided at the upper end of the positioning ring 1. One positioning ring 1 is installed at the lowest end of the outer periphery of the column to be poured concrete. Then, the upper ends of multiple connecting rods 2 are screwed into the threaded hole 14 at the lower end of another positioning ring 1. By stacking the positioning ring 1 on the upper end of the lowest positioning ring 1, the lower ends of multiple connecting rods 2 are inserted into the connecting sleeve 15 and fixed with bolts. Multiple sets of positioning rings 1 and connecting rods 2 are stacked and installed in the same way until the height is the same as or slightly higher than the height of the concrete reinforcement cage, thus completing the support of the auxiliary positioning mechanism.

[0024] Please see Figures 1-4 In this embodiment, the lower end of the gear ring 4 and the positioning ring 1 are slidably connected by a slide rail. The bevel gears 5 are arranged in a circular array and mesh with the gear ring 4. The two ends of the bevel gears 5 and the transmission chamber 3 are rotatably connected by a rotating shaft. The adjusting knob 6 is pulsatorically connected to the bevel gears 5. One end of the limiting plate 7 is fixedly connected to the transmission chamber 3, and the other end of the limiting plate 7 is fixedly connected to the positioning ring 1. The limiting plate 7 has an L-shaped structure design. One end of the lead screw 8 is rotatably connected to the limiting plate 7, and the other end of the lead screw 8 is pulsatorically connected to the bevel gears 5. The limiting plate 7 and the lead screw 8 are arranged in a ring array. The drive plate 9 has a U-shaped structure design. The two sides of the drive plate 9 and the limiting plate 7 slide against each other. The lead screw 8 and the drive plate 9 are threadedly connected. By rotating any one of the adjustment knobs 6 on the outside of each positioning ring 1, the bevel gear 5 drives the toothed ring 4 to slide and deflect inside the transmission chamber 3, thereby causing multiple bevel gears 5 to rotate simultaneously, driving the lead screw 8 to rotate. The drive plate 9 slides on the outside of the limiting plate 7, controlling multiple clamping plates 10 to simultaneously clamp and position the casting template.

[0025] Please see Figures 2-5In this embodiment, the second lead screw 12 is arranged to penetrate the transmission chamber 3 both inside and out. The second lead screw 12 and the transmission chamber 3 are threadedly connected. The locking block 13 is located inside the transmission chamber 3 and is rotatably connected to the lower end of the second lead screw 12. The lower end of the locking block 13 and the toothed ring 4 are tightly fitted together by an anti-slip pad. The upper end of the connecting rod 2 is threadedly connected to the threaded hole 14. The lower end of the connecting rod 2 is slidably fitted to the inner side of the connecting sleeve 15 and is detachably connected to the connecting sleeve 15 by bolts. By rotating the knob 11, the second lead screw 12 is rotated so that the locking block 13 and the surface of the toothed ring 4 are tightly fitted together by the anti-slip pad, thereby limiting and locking the toothed ring 4 and preventing the pressure plate 10 from loosening. When the positioning auxiliary mechanism needs to be disassembled later, the pressure plate 10 of the positioning ring 1 can be moved away from the casting template by rotating any one of the adjustment knobs 6, which facilitates the subsequent disassembly and improves the disassembly efficiency.

[0026] During the work, a positioning ring 1 is installed at the lowest point of the outer periphery of the column to be poured concrete. Then, the upper ends of multiple connecting rods 2 are screwed into the threaded holes 14 at the lower end of another positioning ring 1. By stacking the positioning rings 1 on top of the lowest positioning ring 1, the lower ends of multiple connecting rods 2 are inserted into the connecting sleeves 15 and fixed with bolts. Multiple sets of positioning rings 1 and connecting rods 2 are stacked and installed in the same way until the height is the same as or slightly higher than the height of the concrete reinforcement cage. A pouring template is set on the inner side of multiple positioning rings 1. By rotating any one of the adjusting knobs 6 on the outer side of each positioning ring 1, the bevel gear 5 drives the toothed ring 4. The sliding deflection inside the transmission chamber 3 causes multiple bevel gears 5 to rotate simultaneously, driving the lead screw 8 to rotate. The drive plate 9 slides outside the limiting plate 7, controlling multiple clamping plates 10 to simultaneously clamp and position the casting template. By rotating the knob 11, the lead screw 12 is controlled to rotate, so that the locking block 13 and the surface of the gear ring 4 are tightly attached through the anti-slip pad, realizing the limiting and locking of the gear ring 4 and preventing the clamping plate 10 from loosening. When the positioning auxiliary mechanism needs to be disassembled later, the clamping plate 10 of the positioning ring 1 can be moved away from the casting template by rotating any one of the adjustment knobs 6, which facilitates the subsequent disassembly and improves the disassembly efficiency.
