Technical Field

[0001] This utility model relates to the technical field of construction equipment for prefabricated components in port engineering, and particularly to a device for lifting transverse steel bars on the outer wall of a caisson. Background Technology

[0002] Caissons, as large precast components commonly used in port engineering, can weigh up to 8,000 tons and are typically formed using a layered casting process. In scenarios with a small number of components and limited space, the reinforcement of the caisson's outer walls is often constructed using a manual splicing and tying method. Because the transverse reinforcement requires work at heights, workers must climb, posing a high safety risk, resulting in low construction efficiency, and making it difficult to control the spacing and quality of the reinforcement tying.

[0003] The lack of specialized equipment for lifting horizontal steel bars at high points on the outer wall of caissons in the current technology leads to poor construction safety, low efficiency, and unstable quality. There is an urgent need for a lightweight, efficient, and safe lifting device to solve the above problems. Utility Model Content

[0022] See appendix Figures 1 to 4 This paper presents an illustrative embodiment of the transverse steel bar lifting device for the outer wall of a caisson proposed in this utility model. The transverse steel bar lifting device for the outer wall of a caisson includes a fixed base 1, a support structure 2, and a lifting device 3.

[0023] See appendix Figure 1 and Figure 3 The fixed base 1 is detachably connected to the operating platform 4 inside the caisson. One end of the support structure 2 is connected to the fixed base 1, and the other end of the support structure 2 cantilevered outwards from the steel reinforcement skeleton 5 of the caisson. The lifting device 3 is installed at the cantilevered end of the support structure 2 and is used to lift the transverse steel reinforcement 51 of the outer wall of the caisson. The fixed base 1 is a U-shaped steel plate structure, which is integrally connected by a first steel plate 11, a second steel plate 12, and a third steel plate 13. The first steel plate 11 and the third steel plate 13 extend laterally and are parallel to each other. The length of the first steel plate 11 is longer than the length of the third steel plate 13. The second steel plate 12 extends vertically and is perpendicularly connected to the same side end of the first steel plate 11 and the third steel plate 13, respectively. The first steel plate 11 is used to connect the support structure 2, and the third steel plate 13 is used to clamp the operating platform 4 inside the caisson. The fixed base 1 adopts a U-shaped steel plate structure, and the detachable connection is achieved by clamping the operating platform 4 inside the caisson through the third steel plate 13. No welding is required, which facilitates quick installation and disassembly and is suitable for different construction scenarios.

[0024] The first steel plate 11, the second steel plate 12, and the third steel plate 13 are all made of 10mm thick steel plates, which can ensure that the fixed base 1 has sufficient structural strength and load-bearing capacity, providing a solid support foundation for the entire device.

[0025] See appendix Figure 1 and Figure 3 The support structure 2 includes a main rod 21 and a support member 22. One end of the main rod 21 is connected to the first steel plate 11 of the fixed base 1, and the other end of the main rod 21 is a cantilever end. One end of the support member 22 is connected to the middle area of ​​the main rod 21, and the other end of the support member 22 is supported on the operating platform 4 inside the caisson. The main rod 21 and the support member 22 included in the support structure 2 form a stable support system, improving the overall structural load-bearing capacity and safety of the device.

[0026] See appendix Figure 1 The connection angle between the main rod 21 and the first steel plate 11 is 20°~40°. The cantilever angle can be adjusted according to construction needs to optimize the operating range of the lifting device and adapt to the lifting requirements of transverse reinforcing bars of different heights. In this embodiment, the connection angle between the main rod 21 and the first steel plate 11 is 30°.

[0027] Both the main rod 21 and the support component 22 are made of galvanized steel pipe with a diameter of 50mm. Galvanized steel pipe has good corrosion resistance and structural strength, which can extend the service life of the device, reduce maintenance costs, and adapt to the humid environment of port engineering.

[0028] The main rod 21 and the first steel plate 11 are fixedly connected by welding, which can ensure the connection strength and stability of the two, enhance the overall rigidity of the support structure 2, and ensure that the device is stable and reliable during the lifting process.

[0029] See appendix Figure 1 and Figure 2 The support structure 2 also includes a pad 23, which is fixedly installed at the end of the support member 22 away from the main rod 21, and is used to contact and support the operating platform 4 inside the caisson. The pad 23 increases the support contact area, disperses pressure, and prevents the support member 22 from causing local damage to the operating platform 4 inside the caisson.

[0030] See appendix for further details. Figure 1 The lifting device 3 includes a winch 31 and a traction rope 32. The winch 31 is fixed to the cantilever end of the main pole 21. One end of the traction rope 32 is connected to the drum of the winch 31, and the other end of the traction rope 32 is used to connect to the transverse reinforcing bars 51 of the outer wall of the caisson for lifting operations. The structure is simple and the transmission is efficient, ensuring that the reinforcing bars are stably lifted to the designated position.

[0031] The winch 31 is welded to the cantilever end of the main pole 21, and a predetermined distance is reserved between the winch 31 and the cantilever end of the main pole 21. This ensures a firm connection, avoids interference at the ends, and provides sufficient space for winch operation and rebar hoisting.

[0032] The winch 31 is a wireless remote-controlled winch, equipped with a remote control component for remotely controlling its start, stop, and lifting actions. The winch 31 is a wireless remote-controlled winch with a built-in remote control component, allowing for remote control of its start, stop, and lifting, eliminating the need for close-range manual operation, reducing the risks of working at heights, and improving the convenience of construction operations.

[0033] In this embodiment, 2-4 lifting devices for the transverse reinforcing bars 51 of the caisson's outer wall can be selected to perform the lifting operation together, depending on the length of the bars. See Appendix. Figure 4 Four horizontal steel reinforcement lifting devices for the outer wall of the caisson 6 are installed as a group, and their lifting and lowering are controlled remotely. One worker assists with the steel reinforcement hooks below. See appendix. Figure 3 The transverse reinforcing bars 51 of the caisson's outer wall are remotely lifted to their installation position and tied to the vertical reinforcing bars 52 of the caisson's outer wall. Then, the next reinforcing bar is lowered and hoisted. When the transverse reinforcing bars 51 of the caisson's outer wall are 4-10m long, they can be lifted to a height of 4m.

[0034] In the above illustrative embodiment, the transverse steel bar lifting device for the outer wall of the caisson consists of a fixed base, a support structure and a lifting device. It has a simple structure, is lightweight, and has low manufacturing cost. Lifting the steel bars by the device can avoid manual climbing to high places, reduce safety risks, reduce personnel configuration, and improve construction efficiency.

[0035] The following is in conjunction with the appendix Figures 1 to 4 The working process of one embodiment of the transverse steel bar lifting device for the outer wall of the caisson of this utility model is described below: Installation: The third steel plate 13 of the fixed base 1 is snapped into the operating platform 4 inside the caisson, ensuring a stable connection between the U-shaped steel plate structure and the platform. One end of the main rod 21 is fixed to the first steel plate 11 (at a 30° angle) by welding. One end of the support member 22 is connected to the middle of the main rod 21, and the other end is supported on the operating platform 4 inside the caisson via a pad 23, forming a stable support structure 2. The winch 31 with a remote control component is welded to the cantilevered end of the main rod 21 (with reserved operating space at the end), and connected to the traction rope 32. Depending on the length of the transverse reinforcing bars 51, 2-4 units are spaced at intervals along the platform 4 outside the caisson 6 (e.g., ...). Figure 4 (As shown).

[0036] Rebar hook: The worker operates the platform 4 inside the caisson and hooks the other end of the traction rope 32 to the horizontal rebar 51 of the outer wall of the caisson to be lifted, ensuring that the hook is secure.

[0037] Remote lifting: The winch 31 is activated via a remote control unit, allowing multiple devices to simultaneously lift the reinforcing bar 51, preventing it from tilting; the winch is controlled to smoothly lift the reinforcing bar to the installation position (e.g., ...). Figure 3 (As shown).

[0038] Binding and fixing: After the steel bars are in place, the workers bind and fix the horizontal steel bars 51 and the vertical steel bars 52 on the working surface of the outer wall of the caisson to complete the installation.

[0039] Cyclic operation: After the binding is completed, the remote-controlled winch 31 lowers the traction rope 32, releases the hook and resets, and repeats the above steps to hoist the next horizontal steel bar until the binding operation of the steel bars in this layer is completed.

[0040] Device disassembly: After the construction in this area is completed, the fixed base 1 is removed from the operating platform 4 and transferred to the next work point for reuse.

[0041] The entire process replaces manual climbing with mechanical lifting, and combined with remote control, it achieves efficient operation, significantly reducing safety risks and manpower input.

[0042] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0043] The above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
