Description

Technical Field

[0001] The utility model relates to a reinforced lifting lug and belongs to the technical field of sea breeze construction equipment. Background Art

[0002] The foundation of offshore wind power often adopts the jacket foundation, and the general application scenarios include the jacket foundation of offshore booster station and the foundation of wind turbine unit, etc. It is usually manufactured in sections and assembled on land, and then transported to the offshore location for installation by water. The jacket is generally a steel truss structure, welded by large-diameter, thick-walled low-alloy steel pipes, with large size and heavy weight. Conventional lifting lugs can only be fixed by surface contact welding (see Chinese patent announcement number CN108455739A), and there is a problem that it cannot bear large loads. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a reinforced lifting eye.

[0004] The utility model is realized through the following technical solutions.

[0005] The utility model provides a reinforced lifting lug, comprising:

[0006] Reinforced lifting lug structure capable of carrying large loads.

[0007] The reinforced lifting ear structure comprises:

[0008] When in use, two parallel and spaced hanging ear plates are welded to the outside of the pipe frame;

[0009] A circular arc plate capable of fitting the outside of the welding pipe frame is fixed on the inner surface between the two lifting ear plates;

[0010] An upper bracket and a lower bracket are fixed to the upper and lower parts of the lug plate, which can be welded and fixed to the outside of the conductor frame for secondary reinforcement.

[0011] Reinforcement rings are fixed on the inner and outer surfaces of the two lifting ear plates located at the through holes, and the reinforcement rings of the two lifting ear plates are concentric in the horizontal direction.

[0012] The upper toggle plate is provided with an arc-shaped opening for guiding and accommodating the cable connected to the hook.

[0013] A connecting column is fixed between the two lifting ear plates away from the pipe frame.

[0014] The connecting column is provided with a plurality of limiting protrusions.

[0015] The beneficial effect of the utility model is that the inner surfaces between the lifting ear plates are welded to the outside of the catheter frame through arc plates, and at the same time, the upper and lower parts of the lifting ear plates can be welded and fixed to the outside of the catheter frame through upper elbow plates and lower elbow plates for secondary reinforcement, thereby improving the bearing capacity of the two lifting ear plates on the catheter frame, and solving the problem that conventional lifting ears can only be fixed by surface contact welding and cannot bear large loads.

[0021] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0022] like Figures 1 to 3 shown.

[0023] A reinforced lifting lug of the present application comprises:

[0024] A through hole 21 is provided for hooking the hook into the ear plate 2, and the ear plate 2 is parallel and spaced apart. A circular arc plate 6 is welded and fixed on the inner surface between the two ear plates 2 close to the pipe frame 7, and the circular arc plate 6 can fit the outside of the pipe frame 7, and the two ear plates 2 are welded to the outside of the pipe frame 7 to strengthen them.

[0025] The reinforcement rings 1 are welded and fixed to the inner and outer surfaces of the two lifting ear plates 2 located at the through holes 21 . The reinforcement rings 1 of the two lifting ear plates 2 are concentric in the horizontal direction.

[0026] An upper toggle plate 4 is welded and fixed on the upper part of the ear plate 2, and the upper toggle plate 4 is welded and fixed to the outside of the conductor frame 7 at the upper part of the ear plate 2 for reinforcement connection. The upper toggle plate 4 is provided with an arc-shaped opening 41 for guiding and accommodating the cable connected to the hook; a lower toggle plate 5 is welded and fixed on the lower part of the ear plate 2, and the lower toggle plate 5 is welded and fixed to the outside of the conductor frame 7 at the lower part of the ear plate 2 for reinforcement connection.

[0027] A connecting column 3 is welded and fixed between the two lifting ear plates 2 far away from the conductor frame 7, and a limiting protrusion 31 is provided on the connecting column 3. Multiple limiting protrusions 31 combined with the arc-shaped opening 41 limit the overall position of the hook and the cable connecting the hook, so that the position of the hook and the cable connecting the hook is stable and not prone to swing.

[0028] The reinforced lifting lug of the present application is composed of two lifting lug plates 2, and the inner surfaces between the lifting lug plates 2 are welded to the outside of the catheter frame 7 through the arc plate 6. At the same time, the upper and lower parts of the lifting lug plates 2 can be welded and fixed to the outside of the catheter frame 7 through the upper elbow plate 4 and the lower elbow plate 5 for secondary reinforcement, thereby improving the bearing capacity of the two lifting lug plates 2 on the catheter frame 7, and solving the problem that the conventional lifting lugs can only be fixed by surface contact welding and cannot bear large loads.
