Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary equipment for building construction, specifically relating to a lifting device for a detachable precast wall of a diversion embankment. Background Technology

[0002] A diversion breakwater is a type of structure used along the coast, located beneath still water, to protect the coastline and divert currents. Rectangular structures are common, and they are typically prefabricated in a factory before being transported to the site for installation. Due to the breakwater's significant weight, custom-made lifting boxes are pre-embedded inside during fabrication. These boxes are hooked onto the breakwater during lifting. However, once installed, these lifting boxes cannot be removed, and proper sealing and corrosion protection are required, increasing prefabrication costs. Therefore, designing a reusable lifting device is a pressing technical challenge for those skilled in the art. Utility Model Content

[0003] To address the aforementioned issues, this utility model discloses a detachable lifting device for the precast wall of a diversion embankment. It adds a high-strength bolt connection between the base plate and the concrete, resulting in a simple structure, low cost, convenient loading and unloading, reusability, safety, practicality, and high production efficiency.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A lifting device for a detachable precast wall of a diversion embankment includes a base and lifting rings. The base is U-shaped and includes a bottom plate and left and right side plates. The bottom plate has multiple mounting holes. The lifting rings are arranged perpendicular to the bottom plate and two of them are arranged in parallel. The outer side of the lifting rings extends and is welded to the bottom plate and the left and right side plates to form a whole.

[0006] As an improvement of this utility model, the thickness of the base plate and the left and right side plates is 20mm.

[0007] As an improvement of this utility model, the thickness of the lifting ring is 40mm.

[0008] As an improvement of this utility model, the two lifting rings are arranged coaxially.

[0009] As an improvement of this utility model, the number of mounting holes is ≥4, and they are evenly distributed on the base plate.

[0010] The beneficial effects of this utility model are as follows:

[0011] This utility model discloses a lifting tool for a detachable precast wall of a diversion embankment. It adds a high-strength bolt connection between the base plate and the concrete. The structure is simple, the cost is low, the lifting is convenient and quick, it can be disassembled and reused, it is safe and practical, and the production efficiency is high.

[0018] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0019] As shown in the figure, the lifting device for the detachable precast wall of the diversion embankment of this utility model includes a base 1 and a lifting ring 2. The base is U-shaped and includes a bottom plate 3 and left and right side plates 4. The bottom plate 3 is provided with a plurality of mounting holes 5. The lifting ring 2 is set perpendicular to the bottom plate 3. Two lifting rings 2 are set parallel to each other. The outer side of the lifting ring 2 extends and is welded to the bottom plate 3 and the left and right side plates 4 to form a whole.

[0020] The precast wall of the diversion submerged dike described in this utility model involves pre-embedding a certain number of high-strength bolts 6 (e.g., 8) according to design requirements during prefabrication. Then, a special lifting tool is fabricated. First, a base plate 3 is fabricated according to design requirements. The base plate 3 has multiple mounting holes 5, the positions of which are exactly the same as the positions of the pre-embedded bolts. Figure 3 As shown, the left and right side plates 4 and the lifting ring 2 are then welded together. During use, the base plate 3 of the lifting device is fixed to the pre-installed high-strength bolts 6, secured with double nuts (steel pad 9, matching nut 8, and lock nut 7 are installed sequentially). Figure 4 As shown, the pin passes through the center hole of the two lifting rings 2, the hook hooks the pin and begins to lift. After one wall piece is installed in place, the fixing nut is loosened to remove the lifting device, and the other wall piece is fixed. The lifting is repeated. This utility model has a simple structure, low cost, convenient and quick lifting, can be disassembled and reused, is safe and practical, and has high production efficiency.

[0021] The thickness of the base plate 3 and the left and right side plates 4 of this utility model is 20mm, and the thickness of the lifting ring 2 is 40mm, ensuring safety and reliability.

[0022] The two lifting rings 2 described in this utility model are coaxially arranged, and the pin inserted into the two lifting rings 2 will not easily slip out.

[0023] The number of mounting holes 5 in this utility model is ≥4, and they are evenly distributed on the base plate 1 so that the force is evenly distributed during hoisting.

[0024] It should be noted that the above content merely illustrates the technical concept of this utility model and cannot be used to limit the scope of protection of this utility model. For those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and all such improvements and modifications fall within the scope of protection of the claims of this utility model.
