Description

Technical Field

[0001] This application relates to the field of lifting devices, and in particular to a convenient and adjustable rebar cage lifting device. Background Technology

[0002] In the construction of pile foundations for bridges, high-rise buildings, and high-speed railways, it is necessary to excavate pile holes, place the assembled reinforcing cage into the pile holes, and then pour concrete into the pile holes to fix the reinforcing cage. Since the pile holes are generally quite deep, the reinforcing cage usually needs to be hoisted using lifting equipment.

[0003] Current rebar cage lifting equipment mainly consists of a front hook and a rear hook. Both hooks are connected to the crane via lifting ropes and are respectively engaged with both ends of the rebar cage. During the rebar cage lifting process, the horizontally placed rebar cage is first lifted to a vertical position on the ground. Then, the rear hook is released to lower the rebar cage into the pile hole. After the rebar cage contacts the bottom of the pile hole, the worker can release the front hook, completing the rebar cage lifting process.

[0004] In actual use, the length of the hoisted steel cage outside the pile hole is relatively long. At this time, workers need to use a ladder to disassemble the front hook, which makes the disassembly and assembly of the hoisting equipment more cumbersome and less safe, so it needs to be improved. Utility Model Content

[0005] To address the aforementioned issues, this application provides a convenient and adjustable rebar cage lifting device.

[0006] This application provides a convenient and adjustable rebar cage lifting tool, which adopts the following technical solution:

[0007] A convenient and adjustable rebar cage lifting device includes a hook and several lifting seats. The hook and each lifting seat are connected to a crane via lifting ropes. Each lifting seat is connected to a lifting ring. A first notch is provided on the lifting ring. A moving groove is provided in the lifting ring. A closing strip is slidably connected in the moving groove. The closing strip is used to close the first notch. The lifting seat is provided with a control component for controlling the movement of the closing strip.

[0008] By adopting the above technical solution, when a lifting platform is needed, the worker connects the hook to the rebar cage. The worker then uses the control component to move the closing strip to open the first gap, allowing the lifting ring to be engaged with the rebar cage. The worker then uses the control component to close the first gap, completing the installation of the lifting equipment. After the rebar cage is hoisted, the worker uses the control component to open the first gap again, separating the lifting ring from the rebar cage. This reduces the need for workers to climb ladders, thus improving the convenience of using the lifting equipment.

[0009] Preferably, the control component includes a control bar and a tension spring. The lifting base has a control groove. The control bar is slidably connected in the control groove. One end of the tension spring is connected to the bottom of the control groove and the other end is connected to the control bar. The moving groove is connected to the control groove. The control bar has a first rack, and the closing bar has a second rack that cooperates with the first rack.

[0010] By employing the above technical solution, when the tension spring is in its initial state, it provides tension to the control bar, at which point the closing bar seals the first gap. When it is necessary to open the first gap, the worker pulls the control bar, which moves the first rack. The first rack controls the movement of the second rack, which in turn controls the movement of the closing bar, thus opening the first gap. After the worker separates the lifting ring from the rebar cage, the control bar automatically resets under the rebound force of the tension spring, allowing the closing bar to re-close the first gap.

[0011] Preferably, the closing strip is provided with a positioning block, the lifting ring is provided with a positioning groove, and the positioning block is disposed in the positioning groove.

[0012] By adopting the above technical solution, the positioning block and the positioning groove cooperate to provide positioning for the sealing strip, so that the sealing strip can more stably close the first gap.

[0013] Preferably, the first notch of the lifting ring is provided with a guide arc surface.

[0014] By adopting the above technical solution, the guide arc surface provides guidance for the steel cage, so that the lifting ring can be stably attached to the steel cage.

[0015] Preferably, the hoisting base is provided with a protective arc surface.

[0016] By adopting the above technical solution, the protective arc surface makes the lifting rope less likely to be damaged by the lifting seat.

[0017] Preferably, the end of the control bar away from the tension spring is provided with a plurality of positioning rods, each of the positioning rods is provided with an arc tube clamp, and each of the arc tube clamps is provided with a second notch.

[0018] By adopting the above technical solution, after the lifting ring is attached to the reinforcing cage, the worker uses the second notch to attach the curved pipe to the reinforcing cage. At this time, the positioning rod provides a limit to the control bar, making it difficult for the control bar to move during use, and also facilitates the worker's subsequent pulling of the control bar.

[0019] Preferably, one end of the positioning rod is provided with a connecting cylinder and the other end is provided with a connecting post. The connecting cylinder is slidably connected to the positioning rod, and the connecting post is threadedly connected to the inner wall of the adjacent connecting cylinder. The control bar is provided with a fixing post, and the inner wall of the connecting cylinder on the positioning rod near the control bar is threadedly connected to the fixing post.

[0020] By adopting the above technical solution, when the positioning rods are needed, the worker moves and rotates the connecting cylinder, so that the positioning rod near the control bar connects to the fixed column. Adjacent positioning rods are then connected to the connecting column via the connecting cylinder, completing the connection between the positioning rods and between the positioning rods and the control bar.

[0021] Preferably, the positioning rod has a limiting ring groove, the connecting cylinder has a limiting ring, the limiting ring is disposed in the limiting ring groove, and the limiting ring is slidably connected to the inner wall of the limiting ring groove.

[0022] By adopting the above technical solution, the limiting ring and the limiting ring groove cooperate to make the connecting cylinder difficult to separate from the positioning rod.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] By incorporating lifting rings, sealing strips, and control components, the control components manage to close or open the first notch of the lifting ring, reducing the steps workers need to take when climbing ladders and thus improving the ease of use of the lifting equipment.

[0025] By setting a positioning block, the positioning block provides positioning for the closing strip, so that the closing strip can close the first gap more stably;

[0026] By setting a positioning rod, the curved pipe clamp on the positioning rod cooperates with the steel cage, which on the one hand provides convenience for workers to pull the control bar, and on the other hand provides a limit to the control bar, reducing the possibility of the control bar moving during use.

Detailed Implementation

[0031] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0032] This application discloses a convenient and adjustable rebar cage lifting tool. (Refer to...) Figure 1 and Figure 2 A convenient and adjustable rebar cage lifting tool includes a hook 1 and several lifting seats 2, all connected to a crane via lifting ropes 3. Each lifting seat 2 is equipped with a lifting ring 4, and each lifting ring 4 has a first notch 41. Each lifting ring 4 also has a moving groove 42, in which a closing strip 5 is slidably connected, used to close the first notch 41. The lifting seat 2 is equipped with a control component 6 for controlling the movement of the closing strip 5. The control component 6 controls the movement of the closing strip 5 to open the first notch 41, allowing the worker to engage the lifting ring 4 with the rebar cage. After the rebar cage is lifted, the worker again uses the control component 6 to control the movement of the closing strip 5 to open the first notch 41, allowing the lifting ring 4 to be separated from the rebar cage. This reduces the need for workers to climb ladders, thus improving the convenience of using the lifting tool.

[0033] Reference Figure 2 The control component 6 includes a control bar 61 and a tension spring 62. A control groove 21 is provided on the lifting base 2, and the control bar 61 is slidably connected in the control groove 21. One end of the tension spring 62 is connected to the bottom of the control groove 21, and the other end is connected to the control bar 61. The moving groove 42 is connected to the control groove 21. The control bar 61 is provided with a first rack 611, and the closing bar 5 is provided with a second rack 51 that cooperates with the first rack 611.

[0034] Reference Figure 2 and Figure 3 To facilitate the worker's pulling of the control bar 61, a number of positioning rods 7 are connected to the end of the control bar 61 away from the tension spring 62. Each positioning rod 7 is connected to an arc-shaped pipe clamp 71, and each arc-shaped pipe clamp 71 has a second notch 711. In this embodiment, the positioning rods 7 can be made of thin steel pipe or fiberglass.

[0035] When hoisting the rebar cage, the worker pulls the positioning rod 7, which moves the adjacent positioning rod 7, thereby moving the control bar 61. The control bar 61 pulls the tension spring 62, putting it in a stretched state. Simultaneously, the control bar 61 moves the first rack 611. The first rack 611 controls the movement of the second rack 51, which in turn moves the closing bar 5, opening the first notch 41. The worker can then attach the lifting ring 4 to the rebar cage. Releasing the positioning rod 7 allows the closing bar 5 to reset and close the first notch 41 under the rebound force of the tension spring 62. The worker then attaches the arc clamp 71 to the rebar cage. At this point, the positioning rod 7 provides a limit to the control bar 61, reducing the possibility of movement during use. After the rebar cage is hoisted, the worker repeatedly pulls the positioning rod 7 to open the first notch 41, separating the lifting ring 4 from the rebar cage. This reduces the need for workers to climb ladders, thus improving the convenience of using the hoisting equipment.

[0036] Reference Figure 2 To facilitate the connection between two adjacent positioning rods 7 and between the positioning rod 7 and the control bar 61, each positioning rod 7 has a connecting cylinder 72 at one end and a connecting post 73 at the other end. The connecting cylinder 72 is slidably connected to the positioning rod 7, and the connecting post 73 is threadedly connected to the inner wall of the adjacent connecting cylinder 72. The control bar 61 has a fixing post 612, and the inner wall of the connecting cylinder 72 on the positioning rod 7 closest to the control bar 61 is threadedly connected to the fixing post 612.

[0037] Furthermore, a limiting ring groove 74 is provided on the positioning rod 7, and a limiting ring 721 is fixed on the connecting cylinder 72. The limiting ring 721 is disposed in the limiting ring groove 74 and is slidably connected to the inner wall of the limiting ring groove 74. The limiting ring 721 cooperates with the limiting ring groove 74, making it difficult for the connecting cylinder 72 to separate from the positioning rod 7.

[0038] When the positioning rod 7 is needed, the worker moves and rotates the connecting cylinder 72, so that the positioning rod 7 near the control bar 61 is connected to the fixed post 612. Adjacent positioning rods 7 are then connected to the connecting post 73 through the connecting cylinder 72, completing the connection between each positioning rod 7 and the connection between the positioning rod 7 and the control bar 61.

[0039] Reference Figure 2 A positioning block 52 is fixed on the sealing strip 5, and a positioning groove 43 is provided on the lifting ring 4. The positioning block 52 is set in the positioning groove 43. The positioning block 52 cooperates with the positioning groove 43 to provide positioning for the sealing strip 5, so that the sealing strip 5 can close the first notch 41 more stably.

[0040] Reference Figure 2The lifting ring 4 has a guide arc surface 44 at the first notch 41, which guides the reinforcing cage so that the lifting ring 4 can be stably engaged with the reinforcing cage. The lifting seat 2 has a protective arc surface 22, which makes the lifting rope 3 less likely to be damaged by the lifting seat 2.

[0041] The implementation principle of a convenient and adjustable rebar cage lifting tool according to an embodiment of this application is as follows: When it is necessary to lift the rebar cage, the worker uses the control component 6 to move the closing strip 5 to open the first notch 41. The worker can then attach the lifting ring 4 to the rebar cage and hang the hook 1 on the rebar cage, allowing the crane to lift the rebar cage. When the rebar cage is lifted to be perpendicular to the ground, the worker separates the hook 1 from the rebar cage to lift the rebar cage into the pile hole. After the rebar cage is lifted, the worker pulls the connecting rod to drive the control component 6. The control component 6 controls the closing strip 5 to open the first notch 41, thus separating the lifting ring 4 from the rebar cage. This reduces the step of the worker using a ladder, thereby improving the convenience of using the lifting tool.

[0042] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
