[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0022] As Figures 1 to 5 shown, the present invention provides a positioning device for the steel cage of a cast-in-place pile, including a base 1. An insert block 2 is movably sleeved inside the base 1. A positioning plate 12 is fixedly installed inside the insert block 2. A first round hole 13 is opened on the surface of the positioning plate 12. Long slots 14 are opened on both sides of the first round hole 13. A positioning arc ring 15 is movably installed inside the long slots 14. A second reset spring 16 is elastically installed between the inner side of the long slots 14 and the inner side of the positioning arc ring 15.
[0023] Install the base 1 beside the pile hole, then place the mounting plate 3 above the base 1, and then insert the steel cage from above the second round hole 20. When the steel cage moves to the inside of the first round hole 13, the steel cage contacts the positioning arc ring 15, driving the positioning arc ring 15 to contract into the inside of the long slots 14, causing the positioning arc ring 15 to squeeze the second reset spring 16, deforming the second reset spring 16. The second reset spring 16 releases elastic potential energy to drive the positioning arc ring 15 to move outwards, and the positioning arc ring 15 moves outwards to push the steel cage for positioning.
[0024] By inserting the steel cage from above the second round hole 20, the steel cage contacts the positioning arc ring 15, causing the positioning arc ring 15 to squeeze the second reset spring 16. The second reset spring 16 releases elastic potential energy to drive the positioning arc ring 15 to move outwards to position the steel cage. Compared with the traditional positioning device for the steel cage of a cast-in-place pile, this positioning device for the steel cage of a cast-in-place pile positions the steel cage through the positioning arc ring 15, so that the gap between the steel cage and the pile hole is the same, improving the construction efficiency.
[0025] Among them, a clamping groove 4 is formed inside the base 1, a circular groove 5 is formed outside the insertion block 2, a cylindrical block 6 is movably installed inside the circular groove 5, a connecting rod 9 is movably installed outside the cylindrical block 6, and an inclined block 10 extending into the clamping groove 4 is fixedly installed outside the connecting rod 9.
[0026] When it is necessary to install the mounting plate 3 above the base 1, first insert the insertion block 2 into the base 1, so that the inclined block 10 contacts the base 1, causing the inclined block 10 to contract into the circular groove 5. The inclined block 10 squeezes the first reset spring 11, causing the first reset spring 11 to deform. After the insertion block 2 is completely inserted into the base 1, the first reset spring 11 releases its elastic potential energy to push the inclined block 10 into the clamping groove 4, thereby installing the mounting plate 3 above the base 1.
[0027] By inserting the insertion block 2 into the base 1, the inclined block 10 contracts into the circular groove 5 to squeeze the first reset spring 11. After the insertion block 2 is completely inserted into the base 1, the first reset spring 11 releases its elastic potential energy to push the inclined block 10 into the clamping groove 4. Compared with the traditional positioning device for the steel cage of the cast-in-place pile, this positioning device for the steel cage of the cast-in-place pile plays a connecting role between the base 1 and the insertion block 2 through the inclined block 10, facilitating the installation of the mounting plate 3 above the base 1.
[0028] Among them, two sides of the positioning arc ring 15 are fixedly installed with limit blocks 17 located inside the long groove 14, and a limit rod 18 is fixedly installed inside the long groove 14. The limit blocks 17 are movably sleeved outside the limit rod 18.
[0029] The inward movement of the positioning arc ring 15 drives the inward movement of the limit blocks 17. The limit blocks 17 move inward around the limit rod 18 inside the long groove 14, playing a limiting role on the positioning arc ring 15.
[0030] Among them, a third reset spring 19 is elastically installed between the inner side of the long groove 14 and the inner side of the limit block 17, and the third reset spring 19 is movably connected outside the limit rod 18.
[0031] The limit blocks 17 move inward around the limit rod 18 inside the long groove 14 to squeeze the third reset spring 19, causing the third reset spring 19 to deform. The third reset spring 19 releases its elastic potential energy to push the limit blocks 17 back to their original positions.
[0032] Among them, a movable groove 7 is formed at the bottom of the cylindrical block 6, a round block 8 is movably installed inside the movable groove 7, and the connecting rod 9 is fixedly connected to the outside of the round block 8.
[0033] When the inclined block 10 contracts into the circular groove 5, it drives the connecting rod 9 to contract into the movable groove 7, thereby driving the round block 8 to contract into the movable groove 7.
[0034] Wherein, a first reset spring 11 is elastically installed between the outer side of the cylindrical block 6 and the inner side of the inclined plane block 10, and the first reset spring 11 is movably connected to the outer side of the connecting rod 9.
[0035] When the inclined plane block 10 contracts into the inner part of the circular groove 5, the first reset spring 11 is extruded, and the first reset spring 11 releases elastic potential energy to push the inclined plane block 10 into the inner part of the clamping groove 4.
[0036] Wherein, an installation plate 3 is fixedly installed above the inserting block 2, and a second circular hole 20 is formed on the surface of the installation plate 3, and the second circular hole 20 corresponds to the first circular hole 13.
[0037] The steel reinforcement cage is placed through the second circular hole 20, and the steel reinforcement cage is positioned when passing through the first circular hole 13.
[0038] The working principle and usage process of the utility model are as follows:
[0039] The base 1 is installed beside the pile hole, then the installation plate 3 is placed above the base 1, and then the steel reinforcement cage is inserted from above the second circular hole 20. When the steel reinforcement cage moves into the inner part of the first circular hole 13, the steel reinforcement cage contacts the positioning arc-shaped ring 15, driving the positioning arc-shaped ring 15 to contract into the inner part of the long groove 14, so that the positioning arc-shaped ring 15 extrudes the second reset spring 16, deforming the second reset spring 16. The second reset spring 16 releases elastic potential energy to drive the positioning arc-shaped ring 15 to move outwards, and the positioning arc-shaped ring 15 moves outwards to push the steel reinforcement cage for positioning.
[0040] When it is necessary to install the installation plate 3 above the base 1, first insert the inserting block 2 into the inner part of the base 1, so that the inclined plane block 10 contacts the base 1, causing the inclined plane block 10 to contract into the inner part of the circular groove 5. The inclined plane block 10 extrudes the first reset spring 11, deforming the first reset spring 11. After the inserting block 2 is completely inserted into the inner part of the base 1, the first reset spring 11 releases elastic potential energy to push the inclined plane block 10 into the inner part of the clamping groove 4, thereby installing the installation plate 3 above the base 1.
