Description
Technical Field
The utility model relates to a shipbuilding field, concretely relates to lug is strengthened to embedded structure that boats and ships segmentation stood up usefulness.
Background
In the ship building process, a large ship structure needs to be divided into a plurality of sections suitable for building construction, and the built sections are turned over, lifted and carried. Ordinary lug, the installation scope is restricted, must install at the strong shelves of structure, and be non-structural face position, very restrict, can't be suitable for to some bulkhead segmentation that the structure is slightly weak. Part of the lifting lugs are vertically welded on the ship body sections, and when the ship body turns over, the steel wire ropes connected with the lifting lugs are cut by the free edges of the sections, or the lifting lugs are deformed or broken and fail due to insufficient structural strength.
Disclosure of Invention
The intensity that the structure of lug among the prior art leads to for overcoming is not enough, can't satisfy the not enough of the demand of standing up the handling, the utility model aims to provide an intensity can satisfy the embedded enhancement lug that the segmentation stood up the requirement.
In order to achieve the above purpose, the utility model adopts the technical proposal that:
an embedded reinforced lifting lug comprises a stressed main board, wherein the stressed main board is arranged between two longitudinal bones of a ship subsection, two ends of the stressed main board are respectively welded with the side surfaces of the two longitudinal bones, the bottom of the stressed main board is welded with a ship subsection plane, a lifting lug hole is formed in the stressed main board plane, reinforcing webs are respectively welded on two sides of the lifting lug hole, the lifting lug hole is connected with a steel rope through a lifting ring, and the lifting ring is connected with the stressed main board and the reinforcing webs in a penetrating manner; be connected with between atress mainboard and the boats and ships segmentation and strengthen the channel-section steel, strengthen the channel-section steel both ends and weld atress mainboard and segmentation landing slab respectively.
Furthermore, the two longitudinal beams connected with the stressed main board are respectively connected with the longitudinal beams on the outer side of the stressed main board through reinforcing rib plates, and the reinforcing rib plates are welded between the two longitudinal beams.
Furthermore, two ends of the reinforced channel steel are respectively connected with the platform plate and the stressed main plate of the ship section through a diagonal member in a welding mode.
And furthermore, a semicircular structure concentric with the lifting lug hole extends outwards from the lifting lug hole position and the middle part of the stressed main board.
After taking above technical scheme, the beneficial effects of the utility model are that: the atress mainboard of lug is simultaneously with segmentation and a pair of longitudinal rib welding to further consolidate mainboard and segmentation landing slab through strengthening the channel-section steel, can ensure the lug and stand up the firm of in-process. The lug hole is accepted evenly through semicircular structure, avoids stress concentration point, strengthens the bulk strength in lug hole through a pair of enhancement web, prevents to break. And a pair of longitudinal ribs connected with the stressed main plate is reinforced, so that the deformation of the longitudinal ribs is prevented from influencing the strength of the lifting lug. The structure can meet the installation requirement, ensures the strength and meets the requirement of turning over in sections.

fig. 2 is a top view of the present invention.
Detailed Description
The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings:
as shown in fig. 1 and 2, the embedded reinforced lifting lug is composed of a stressed main plate 1, a reinforced web plate 2 and a reinforced channel steel 3, wherein the thickness of the stressed main plate is not less than 24mm, the stressed main plate is welded between two longitudinal bones 4 of a ship section, two ends of the stressed main plate 1 are respectively welded with the side surfaces of the two longitudinal bones 4, the bottom of the stressed main plate 1 is welded with a ship section plane 5 to form three surface contact connections, and the strength is ensured. In order to avoid the influence of the deformation of the longitudinal frame on the strength of the stressed main board in the turning and lifting process, a pair of longitudinal frames 4 which are welded and connected with the stressed main board 1 are respectively welded and reinforced with the adjacent longitudinal frames on the outer side through reinforcing rib plates 6. The upper middle part of the plane of the stressed main board 1 is provided with a lifting lug hole 7, and a semicircular structure 8 concentric with the lifting lug hole extends outwards, so that the stress distribution is uniform, and the damage caused by stress concentration lifting is avoided. Strengthen web 2 welding at atress mainboard both sides plane, strengthen web 2 and be the ring structure, coaxial with lug hole 7, do the reinforcement to lug hole 7 structure. In order to prevent the stressed main board from deforming when the stressed main board is turned over, a reinforcing channel steel 3 of an inclined strut is welded between the stressed main board 1 and a platform board 9 of a ship body section, two ends of the reinforcing channel steel 3 are respectively welded and connected with corresponding connection objects through a pair of angle irons 10, the welding area is increased, and the welding stability of the reinforced channel steel is improved.
According to the technical scheme, a frame form is formed among the stressed main plate 1 of the lifting lug, the segmented platform plate 9, the segmented plane 5 and the longitudinal frame 4, so that the integral strength of the segmented turnover is ensured, and no obvious deformation is caused.
