Detailed Implementation

[0024] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0025] Please see Figures 1-6 A hoisting device for a reinforcing cage of a cap beam includes a mounting frame 1; the mounting frame 1 is provided with a first adjusting component 2, the first adjusting component 2 is connected to symmetrically distributed second adjusting components 3, the second adjusting components 3 are connected to symmetrically distributed fixing frames 4, the fixing frames 4 are provided with a limiting component 5 and a lifting component 6, and protective components 12 are provided on both sides of the mounting frame 1. The first adjusting component 2 and the second adjusting component 3 are used to adjust the position of the lifting component 6, the limiting component 5 is used to limit the two sides of the reinforcing cage of the cap beam, the lifting component 6 is used to connect the lifting equipment to the reinforcing cage, and the protective components 12 are used to protect the outside of the device.

[0026] The position between the lifting components 6 on the fixed frame 4 is adjusted by the first adjusting component 2 and the second adjusting component 3. The connection position can be adjusted according to the size of the cap beam reinforcement cage, which has good adaptability. The upper two sides of the cap beam reinforcement cage can be limited and fixed by the limiting component 5. During the limiting process, it will contact the lifting component 6, so that the lifting component 6 can be connected with the cap beam reinforcement cage. When the limiting component 5 is released, the lifting component 6 will separate from the cap beam reinforcement cage.

[0027] The limiting component 5 includes a plurality of slide rods 501 slidably connected to the fixing frame 4. One end of the slide rod 501 is provided with a limiting plate 502, and the other end of the slide rod 501 is provided with an outer plate 504. A first elastic element 503 is provided between the limiting plate 502 and the fixing frame 4. Preferably, the first elastic element 503 is a spring. The fixing frame 4 is provided with symmetrically distributed support frames 505 on the side near the limiting plate 502. The support frames 505 are used to limit the continued movement of the limiting plate 502.

[0028] The lifting component 6 includes a slot 608 formed in the lower part of the fixed frame 4. A support base 601 is installed on one side of the fixed frame 4, and a hook 603 is rotatably mounted on the support base 601. An extension plate 604 is installed on the other side of the fixed frame 4. A second elastic element 605 is provided between the extension plate 604 and the hook 603. Preferably, the second elastic element 605 is a spring. A first baffle 606 is installed on the side of the fixed frame 4 near the extension plate 604, and a second baffle 607 is installed on the side of the fixed frame 4 away from the extension plate 604.

[0029] A locking block 7 is installed on the side of the hook 603 near the fixed frame 4. The second baffle 607 has a locking groove 8 that cooperates with the locking block 7. When the hook 603 rotates to be close to the second baffle 607, the locking block 7 on the hook 603 will be locked into the locking groove 8 of the second baffle 607, so as to achieve precise positioning of the hook 603.

[0030] The end of the hook 603 is equipped with symmetrically distributed brackets 9. A rotating shaft 10 is rotatably mounted on the brackets 9, and a roller 11 is mounted on the rotating shaft 10. The roller 11 allows the end of the hook 603 to slide smoothly on the surface of the limiting plate 502 when the limiting plate 502 pushes the hook 603 to rotate.

[0031] The first adjusting component 2 includes two first T-slots 201 symmetrically distributed on the mounting frame 1. A first bidirectional screw 202 is rotatably disposed in one of the T-slots. Both sides of the first bidirectional screw 202 are threadedly connected to first moving blocks 203 that are slidably connected to the first T-slot 201. A first driving member 204 connected to the first bidirectional screw 202 is installed on the outer wall of the mounting frame 1. Preferably, the first driving member 204 is a stepper motor. A guide rod 205 is installed in the other first T-slot 201. Guide blocks 206 are slidably disposed on both sides of the guide rod 205. The first bidirectional screw 202 is driven to rotate by the first driving member 204, so that the two first moving blocks 203 on the first bidirectional screw 202 move, thereby adjusting the distance between the two movable frames 301.

[0032] The second adjusting component 3 includes a movable frame 301 connected to the first movable block 203. The movable frame 301 is fixedly connected to the guide block 206. A second T-slot 302 is provided in the movable frame 301. A second bidirectional screw 303 is rotatably arranged in the second T-slot 302. Both sides of the second bidirectional screw 303 are threadedly connected to second movable blocks 304 that are slidably connected to the second T-slot 302. The second movable blocks 304 are fixedly connected to the fixed frame 4. A second driving component 305 connected to the second bidirectional screw 303 is installed on the outer wall of the movable frame 301. Preferably, the second driving component 305 is a stepper motor. The second bidirectional screw 303 is driven to rotate by the second driving component 305, thereby adjusting the distance between the two second movable blocks 304 on the movable frame 301, that is, changing the distance between the lifting components 6 on the two fixed frames 4.

[0033] The protective component 12 includes sliding cavities 1201 on both sides of the mounting frame 1. A connecting plate 1202 is slidably disposed in the sliding cavity 1201. The connecting plate 1202 is fixedly connected to the connecting rod 1203. The connecting rod 1203 is fixedly connected to the protective plate 1204. A third elastic element 1205 connected to the connecting plate 1202 is disposed in the sliding cavity 1201. Preferably, the third elastic element 1205 is configured as a damping shock absorber. When the outer side of the present invention is impacted, the protective plate 1204 and the third elastic element 1205 can provide impact protection for the lifted cap beam steel cage and the present invention.

[0034] The mounting frame 1 is provided with symmetrically distributed connecting rings 13 for connecting with lifting equipment.

[0035] The working principle of this invention is as follows: the invention is connected to the lifting equipment through the connecting ring 13, and the invention is moved above the cap beam reinforcement cage to be lifted. The distance between the two second adjusting components 3 can be adjusted through the first adjusting component 2, and the distance between the lifting components 6 on the two fixed frames 4 can be adjusted through the second adjusting components 3. Thus, the invention can adjust the connection position between the lifting components 6 and the cap beam reinforcement cage according to the size and specifications of the cap beam reinforcement cage, making the connection between the invention and the cap beam reinforcement cage more stable.

[0036] After the first adjusting component 2 and the second adjusting component 3 are adjusted, the present invention is lowered between the lifting components 6 on both sides of the cap beam reinforcement cage by a lifting device. The two fixed frames 4 on the second adjusting component 3 are brought closer together. During the process of the fixed frames 4 approaching each other, the limiting plate 502 will contact the cap beam reinforcement cage and gradually push the sliding rod 501 to move, so that the first elastic element 503 is compressed. With the help of the limiting plate 502, the two sides of the cap beam reinforcement cage can be limited to a certain extent. When the limiting plate 502 moves a certain distance relative to the fixed frame 4, it will contact the upper end of the hook 603, thereby pushing the hook 603 to rotate around the movable shaft 602 until the upper part of the hook 603 contacts the second baffle 607. At this time, the hook 603 will extend into the cap beam reinforcement cage and hook the reinforcement. Then, the connected cap beam reinforcement cage can be lifted by the lifting equipment, and the second elastic element 605 will be pulled when the hook 603 rotates outward. After the cap beam reinforcement cage is lifted to the designated pier, the two fixed frames 4 on it can be separated by the second adjusting component 3. During the separation of the fixed frames 4, the limiting plate 502 will gradually move away from the fixed frame 4. During this process, under the action of the second elastic element 605, the lower part of the hook 603 is subjected to elastic tension until the lower part of the hook 603 rotates to the position with the first baffle 606. During this process, the hook 603 will disengage from the cap beam reinforcement cage. Therefore, when the hook 603 is connected to and disconnected from the cap beam reinforcement cage, no manual operation by workers is required. The overall connection and disconnection of the hook 603 can be achieved, and the overall operation process is simple.

[0037] This invention adjusts the position between the lifting components 6 on the fixing frame 4 by setting the first adjusting component 2 and the second adjusting component 3. This allows the connection position to be adjusted according to the size and specifications of the cap beam reinforcement cage, providing good adaptability. Furthermore, the limiting component 5 can limit and fix the upper two sides of the cap beam reinforcement cage. During the limiting process, it will contact the lifting component 6, allowing the lifting component 6 to be connected to the cap beam reinforcement cage. When the limiting component 5 is released, the lifting component 6 will separate from the cap beam reinforcement cage. Therefore, when the hook 603 is connected to and disconnected from the cap beam reinforcement cage, no manual operation by workers is required, making the overall operation process simple.

[0038] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
