[0019] Prepare two steel wire ropes, one of which passes through the steel bar ring 3, the steel bar ring 3 is made of steel bars, and the connection with the bent hook 1 is fixed by welding. The bent hook 1 is placed under the wooden formwork, and the notch 2 can clamp the wooden formwork. The other steel wire rope used for lifting passes through the first pull ring 4, and two clamps 8 are placed on the left and right sides of the wooden formwork. When the steel wire rope pulls the first pull ring 4, the top of the first pull ring 4 is round to prevent the steel wire rope from moving and causing the wooden formwork to shake during lifting. The second pull ring 5 drives the connecting rod 6 to swing, and at the same time, the side plate 7 is used to push the clamp 8 to fit onto the wooden formwork, and the two steel wire ropes are fixed together. The wooden formwork is lifted by pulling the steel wire rope through the tower crane, and the upper and lower ends of the wooden formwork are limited to prevent the wooden formwork from falling.

[0020] Specifically, a hanging ring 9 is fixedly installed at the bottom end of the side panel 7, one end of a pull rope 10 is fixedly passed through the inner wall of the hanging ring 9, a bracket 11 is fixedly installed at the top left side of the curved hook 1, a drum 13 is rotatably installed on the left side of the bracket 11, the pull rope 10 is wrapped around the outer wall of the drum 13, a gear 12 is fixedly installed on the front surface of the drum 13, a sleeve 17 is fixedly installed on the left side of the curved hook 1, a nut 19 is fixedly installed on the left side of the inner wall of the sleeve 17, a bolt 18 is screwed on the inner wall of the nut 19, a ring 16 is sleeved on the left side of the outer wall of the bolt 18, a push plate 15 is fixedly installed on the top of the outer wall of the ring 16, a top plate 14 is fixedly installed on the right side of the push plate 15, and the top plate 14 fits tightly with the gear 12.

[0021] During the hoisting process, two steel wire ropes are prepared, one of which passes through the steel bar ring 3, and the curved hook 1 is placed under the wooden formwork. The notch 2 can clamp the wooden formwork, and the other steel wire rope used for hoisting passes through the first pull ring 4. Two clamps 8 are placed on the left and right sides of the wooden formwork. While the steel wire rope pulls the first pull ring 4, the second pull ring 5 drives the connecting rod 6 to swing, and at the same time, the clamps 8 are pushed to fit the wooden formwork through the side plates 7. The two steel wire ropes are fixed together, the curved hook 1 is placed at the bottom end of the wooden formwork, and the clamps 8 are placed at the top end of the wooden formwork. Then, the other end of the pull rope 10 is fixed to the hanging ring on the right, and the pull rope 10 is placed at the bottom end of the wooden formwork. The gear 12 is turned, and the pull rope 10 is wound around the drum 13. The bracket 11 supports the drum 13 and the gear 12, and the pull rope 10 is in a taut state. After the state, the bolt 18 is turned, and the bolt 18 rotates on the inner wall of the nut 19. The right end of the bolt 18 extends into the sleeve 17. The bolt 18 is fixed together with the collar 16 through the bearing. The bolt 18 drives the collar 16 to move together during the movement. The collar 16 drives the top plate 14 to move toward one side of the gear 12 through the push plate 15. The right side of the top plate 14 is provided with a groove matching the gear 12, which can mesh with the gear 12 to achieve the effect of fixing the gear 12. At this time, the pull rope 10 cannot be extended. During hoisting, the wooden template is pressed on the curved hook 1, and the curved hook 1 drives the pull rope 10 to move downward. The pull rope 10 is in a taut state. At this time, the pull rope 10 pushes the splint 8 to move toward one side of the wooden template, so that the splint 8 clamps the wooden template more tightly to prevent the wooden template from falling.

[0022] Specifically, a support rod 28 is fixedly mounted on the bottom end of the curved hook 1 , a rubber tube 29 is fixedly mounted on the bottom end of the support rod 28 , a pull rope 10 passes through the rubber tube 29 , and a hook 30 is fixedly mounted on the other end of the pull rope 10 .

[0023] The support rod 28 can be connected to the rubber tube 29, and the pull rope 10 passes through the rubber tube 29, which can protect the pull rope 10 and reduce the damage of the pull rope 10. The hook 30 can be used to conveniently fix the other end of the pull rope 10 to the hanging ring 9 on the right side.

[0024] Specifically, a through hole 20 is provided at the top end of the side surface of the side plate 7, a horizontal plate 21 passes through the inner wall of the through hole 20, blocks 22 are fixedly assembled on the left and right sides of the lower surface of the horizontal plate 21, a spring 23 is fixedly assembled on the inner side surface of the outer block 22, and the spring 23 fits tightly with the side plate 7, a slot 24 is provided on the upper surface of the clamping plate 8, and the inner wall of the slot 24 is clamped with the inner block 22.

[0025] During the hoisting process, when the splint 8 is swinging, the inner block 22 is clamped into the inner wall of the slot 24, and the spring 23 is elastically deformed due to its own elastic properties. The spring 23 pushes the outer block 22 to move outward, pulling the cross bar 21 to move outward, and the inner block 22 drives the splint 8 to swing through the slot 24, thereby increasing the pressure between the bottom end of the splint 8 and the wooden formwork, thereby enhancing the fixing effect.

[0026] Specifically, a support 26 is fixedly mounted on the bottom end of the outer side surface of the clamping plate 8 , and a roller 27 is rotatably mounted on the outer end of the support 26 .

[0027] During the lifting process, when the pull rope 10 contacts the clamping plate 8, the pull rope 10 contacts the roller 27 on the support 26. The pull rope 10 contacts the roller 27 during the movement, which reduces friction, reduces damage to the pull rope 10, and extends the service life of the pull rope 10.

[0028] Specifically, a rubber plate 25 is fixedly mounted on the inner side of the clamping plate 8 .

[0029] The rubber sheet 25 is fixed to the clamping plate 8 and contacts with the wooden formwork during the hoisting process, which can increase the friction between the wooden formwork and the fixing effect.

[0030] Working principle: During the hoisting of the wooden formwork, two steel wire ropes are prepared, one of which passes through the steel bar ring 3, and the bent hook 1 is placed under the wooden formwork. The notch 2 can clamp the wooden formwork, and the other steel wire rope used for hoisting passes through the first pull ring 4. Two clamps 8 are placed on the left and right sides of the wooden formwork. While the steel wire rope pulls the first pull ring 4, the second pull ring 5 drives the connecting rod 6 to swing, and at the same time, the side plate 7 pushes the clamp 8 to fit the wooden formwork, and the two steel wire ropes are fixed together. The other end of the pull rope 10 is fixed to the hanging ring on the right, and the pull rope 10 is placed at the bottom end of the wooden formwork. The gear 12 is rotated, and the pull rope 10 is wound around the drum 13. The bracket 11 supports the drum 13 and the gear 12. After the pull rope 10 is in a taut state, the bolt 18 is turned, and the bolt 18 rotates on the inner wall of the nut 19. The right end of the bolt 18 extends into the sleeve 17, and the bolt 18 is moved. During the movement, the ring 16 is driven to move together, and the ring 16 drives the top plate 14 to move to one side of the gear 12 through the push plate 15, and can mesh with the gear 12 to achieve the effect of fixing the gear 12. At this time, the pull rope 10 cannot be extended. During hoisting, the wooden template is pressed on the curved hook 1, and the curved hook 1 drives the pull rope 10 to move downward. The pull rope 10 is in a taut state. At this time, the pull rope 10 pushes the clamping plate 8 to move to one side of the wooden template, so that the clamping plate 8 clamps the wooden template more tightly. The inner clamping block 22 is clamped into the inner wall of the clamping groove 24, and the spring 23 is elastically deformed due to its own elastic performance. The spring 23 pushes the outer clamping block 22 to move outward, pulling the cross bar 21 to move outward, and the inner clamping block 22 drives the clamping plate 8 to swing through the clamping groove 24, and the wooden template is hoisted by pulling the steel wire rope through the tower crane, and the upper and lower ends of the wooden template are limited to prevent the wooden template from falling.
