Description

Technical Field

[0001] The invention relates to the technical field of ship lifting, in particular to a ready-to-use, non-removal lifting eye on a ship. Background Art

[0002] Traditionally, the lifting eyes are arranged on the hull structure, and the reverse side of the lifting eyes needs to be reinforced so as to meet the local strength of the structure near the lifting eyes during the lifting process. Generally, the lifting eyes at large tonnage positions cannot be installed on the structural plate without reinforcement on the reverse side. The lifting eyes need to be cut off after use, and the subsequent cutting and processing of the lifting eyes on site will also take a lot of man-hours. Summary of the invention

[0003] In order to solve the problem that the existing lifting eye structure needs to be dismantled after use, the present invention provides a lifting eye that can be used on a ship and does not need to be dismantled.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a non-removable lifting ear for use on a ship, comprising: a flat plate, a rib part fixedly connected to the bottom of the flat plate, the end of the rib part away from the flat plate is fixedly connected to the ship, the top of the flat plate is fixedly connected to an upper lifting ear, the bottom of the flat plate is fixedly connected to a lower lifting ear, both side surfaces of the rib part are fixedly connected to side frames, the side surfaces of the side frames are fixedly connected to fixed shafts, the fixed shaft is parallel to the length direction of the flat plate, and the side surfaces of the fixed shaft are movably connected to hinge baffles.

[0005] As a further description of the above technical solution:

[0006] There are two rib pieces, which are respectively located at two ends of the flat plate.

[0007] As a further description of the above technical solution:

[0008] The lower lifting ear is located between the two rib members, and the side surface of the lower lifting ear is fixedly connected to the side surface of the rib member.

[0009] As a further description of the above technical solution:

[0010] The side surface of the upper hanging ear is provided with an ear hole, and the side surface of the lower hanging ear is provided with an ear hole.

[0011] As a further description of the above technical solution:

[0012] A welding reinforcement piece is fixedly connected to the side surface of the rib piece near the bottom end, and the bottom of the welding reinforcement piece is fixedly connected to the ship.

[0013] As a further description of the above technical solution:

[0014] There are two hinge baffles, which are respectively located on two sides of the flat plate.

[0015] As a further description of the above technical solution:

[0016] The material of the lower lifting lug is ship-grade material, and the surface of the lower lifting lug is processed by sandblasting and free edge grinding.

[0017] The beneficial effects of the present invention are as follows: on the basis of meeting the local strength of the structure near the lifting eye position during the lifting process, the man-hours for subsequent on-site cutting and processing of the lifting eye are reduced, the operating efficiency of the ship during the construction process is improved, and the on-site operating costs and operating difficulties are reduced.

[0025] Please refer to the attached Figure 1-4The present invention provides a non-removable lifting eye for use on a ship, comprising: a flat plate 4, a rib member 3 is fixedly connected to the bottom of the flat plate 4, the end of the rib member 3 away from the flat plate 4 is fixedly connected to the ship, so that the flat plate 4 is parallel to the surface of the ship, an upper lifting eye 1 is fixedly connected to the top of the flat plate 4, the upper lifting eye 1 generally adopts the same lifting eye as the existing structure, the length of the connection part of the upper lifting eye 1 is less than the length of the flat plate 4, and it can be selectively connected in a suitable area (the upper lifting eye 1 is shown in the accompanying drawings as being connected to the middle position of the top of the flat plate 4), a lower lifting eye 2 is fixedly connected to the bottom of the flat plate 4, and both sides of the rib member 3 are fixedly connected There is a side frame 5, and a fixed axis is fixedly connected to the side of the side frame 5, and the fixed axis is parallel to the length direction of the flat plate 4. A hinge baffle 6 is movably connected to the side of the fixed axis, and the hinge baffle 6 can rotate along the fixed axis. When the upper lifting ear 1 is in use, the hinge baffle 6 is downward, and when the upper lifting ear 1 needs to be used, the hinge baffle 6 is upward. When the lifting ear structure is not needed, the side of the hinge baffle 6 is welded to the inner side of the side frame 5. The welding here adopts the spot welding form, which plays a certain protective role on the lower lifting ear 2. When it is reused, the spot welding part is cut off, and the lower lifting ear 2 can be used again.

[0026] In order to further increase the stability of the connection structure of the flat plate 4, two rib members 3 are provided, which are respectively located at the two ends of the flat plate 4, and the lower lifting ear 2 is located between the two rib members 3. The side of the lower lifting ear 2 is fixedly connected to the side of the rib member 3. The second function of the lower lifting ear 2 is to serve as a lifting ear reinforcement plate, which can increase the structural strength of the entire lifting ear structure.

[0027] An ear hole is provided on the side of the upper lifting ear 1, and an ear hole is provided on the side of the lower lifting ear 2. The size of the ear hole is the same as that of the conventional structure. A welding reinforcement 31 is fixedly connected to the side of the rib member 3 near the bottom end. The bottom of the welding reinforcement 31 is fixedly connected to the ship, which can further increase the connection strength of the rib member 3. There are two hinge baffles 6, which are respectively located on both sides of the flat plate 4. The material of the lower lifting ear 2 is ship-grade material, and the surface of the lower lifting ear 2 is sandblasted and free-edge polished, which can ensure that the lifting ear has the same performance of resisting seawater erosion as the ship when not in use, so that it has a longer service life.
