Description

Technical Field

[0001] This utility model relates to the field of shipbuilding tooling technology, specifically to a lifting bracket that can be used for both plate turning and translation. Background Technology

[0002] During shipbuilding, the hoisting of semi-finished products such as plates and frames is frequent, including processes such as turning over and moving. Traditional lifting clamps have a single function and often require welding different types of lifting lugs or clamps for turning over and moving operations. This not only increases the number of lifting clamps and the amount of welding work, but also leads to material waste and extended construction time.

[0003] There are some existing technologies that attempt to solve the above problems. For example, Chinese patent CN213923716U discloses a "new type of lifting lug for ship section lifting and turning". The lifting lug adopts a structure of one lug and two holes, which integrates horizontal lifting and turning functions. By setting a first web plate, a second web plate and reinforcing ribs to enhance the structural strength, the number of lifting lugs is reduced to a certain extent and the lifting efficiency is improved.

[0004] However, this lifting lug structure still has the following drawbacks:

[0005] The lifting lug main plate has an integral straight plate structure, requiring it to be perpendicular to the edge of the frame during tilting operations. This arrangement results in the force direction of the steel cable being inconsistent with the direction in which the lifting lug main plate is welded to the frame during horizontal lifting. The tension generated by the steel cable creates a lateral bending moment on the lifting lug main plate. Even with the addition of reinforcing ribs, this can easily lead to deformation of the lifting lug main plate or even cracking of the welds, posing a safety hazard. Furthermore, this structure fails to optimize the force direction of the lifting lug for the two different working conditions of tilting and horizontal movement, resulting in limited functional integration.

[0006] Therefore, it is necessary to provide a lifting bracket that can be used for both flipping and translating the plate frame to solve the above-mentioned technical problems. Utility Model Content

[0007] The purpose of this utility model is to address the shortcomings of existing technologies by providing a lifting bracket that can be used for both flipping and translating of the frame, thus optimizing the stress structure of the lifting lugs under different working conditions.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A type of lifting bracket that can be used for both flipping and translating a board frame includes a lifting bracket body that is vertically fixed to the top surface of the board frame. The lifting bracket body is a long strip structure, including a flipping section and a translating section. The flipping section and the translating section are arranged at an angle. The longitudinal section of the front end of the flipping section is arc-shaped and has a first ear hole. The flipping section with the first ear hole extends out of the board frame. A first web plate with a longitudinal section of D-shape is fixed to the side of the flipping section. The first web plate has a first through hole. The first through hole and the first ear hole are concentric and have the same diameter. The translating section has a second ear hole. A second web plate with a longitudinal section of circle is fixed to the side of the translating section. A second through hole is opened in the middle of the second web plate. The second through hole and the second ear hole are concentric and have the same diameter. Symmetrically arranged support elbow plates are fixed to the side of the flipping section.

[0010] Preferably, both the first web and the second web are arranged on one side and fixed to the same side of the lifting bracket body. The support elbow plate on one side of the first web is fixed to the first web, and the support elbow plate on the other side is fixed to the turning section.

[0011] Preferably, the bottom of the support elbow plate is provided with drainage holes on the side near the turning section.

[0012] Preferably, the thickness of the lifting bracket body is equal to the thickness of the supporting elbow plate.

[0013] Preferably, the bottom surface of the support elbow plate and the bottom surface of the lifting bracket body are on the same horizontal plane.

[0014] Preferably, the end of the translation segment is a straight edge.

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] 1. Optimized stress structure to avoid deformation of the lifting bracket: The lifting bracket body of this utility model adopts a design structure in which the turning section and the translation section form an angle. This design allows the tension direction of the steel cable to be better aligned with the axial direction of the translation section during translational lifting. This effectively avoids the harmful bending moment caused by the large deviation between the stress direction and the tension direction of the steel cable in the straight plate type lifting lug in the comparative document. As a result, the risk of lifting bracket deformation and weld cracking is significantly reduced, and the safety of lifting operations is improved.

[0017] 2. Clear functional zoning to meet the needs of different working conditions: This utility model clearly divides the lifting code into a turning section and a translation section. This zoning design enables the lifting code to perfectly adapt to the two completely different lifting working conditions of turning and translation, truly realizing "one code for two uses" and strong versatility.

[0018] 3. Reduced material and labor waste, resulting in significant economic benefits: Compared to existing technologies, the construction process is simplified, and compared to comparative documents, the number of reinforcing ribs is reduced, saving material costs. Attached Figure Description

[0027] like Figures 1 to 4As shown, a type of lifting bracket that can be used for both flipping and translating a plate frame includes a lifting bracket body 1 that is welded and fixed perpendicularly to the top surface of the plate frame 10. The lifting bracket body is a long strip structure, including a flipping section and a translating section. The flipping section and the translating section are arranged at a 150° angle. The longitudinal section of the front end of the flipping section is arc-shaped and has a first ear hole 2. The flipping section with the first ear hole extends out of the plate frame. A first web plate 3 with a longitudinal section of D-shape is welded and fixed to the side of the flipping section. The first web plate has a first through hole 4. The first through hole and the first ear hole are concentric and have the same diameter. The translating section has a second ear hole 5. A second web plate 6 with a longitudinal section of circle is welded and fixed to the side of the translating section. A second through hole 7 is opened in the middle of the second web plate. The second through hole and the second ear hole are concentric and have the same diameter. The first and second web plates can be arranged on one side or both sides. When arranged on one side, the first and second web plates are welded and fixed to the same side of the lifting bracket body. At the same time, the outer side of the first web plate is welded and fixed with a support elbow plate 8. Another support elbow plate is welded and fixed on the other side of the turning section. To ensure structural strength, the thickness of the lifting bracket body is equal to the thickness of the support elbow plate. In order to make the welding between the lifting bracket and the plate frame more secure, the bottom surface of the support elbow plate is designed to be on the same horizontal plane as the bottom surface of the lifting bracket body. During welding, except for the bottom surface of the lifting bracket body that extends out of the plate frame, the remaining bottom surface of the lifting bracket body and the bottom surface of the support elbow plate are welded and fixed to the plate frame. The bottom of the support elbow plate is provided with drainage holes 9 on the side near the turning section. The end of the translation section is a straight edge.

[0028] The principle of a type of lifting bracket that can be used for both flipping and translating a plate frame:

[0029] The lifting bracket body 1 adopts a partitioned design combining a flipping section and a translation section. The flipping section, with the first lug hole, extends beyond the plate frame 10, facilitating hook connection and enabling plate frame flipping. The remaining part of the flipping section and the translation section are located inside the plate frame for horizontal lifting. The unique design of the flipping section and the translation section forming an angle (preferably 150°) ensures that the direction of the cable tension during translation lifting is basically consistent with the axial direction of the translation section, avoiding the harmful bending moment caused by the inconsistency between the force direction and the cable tension direction of the straight plate type lifting lug during translation.

[0030] A method for using a lifting bracket that can be used for both flipping and translating a board frame:

[0031] Four vertical hangers are symmetrically arranged on the top surface of the horizontally placed frame. The part of the hanger body with the first ear hole extends out of the frame. The turning section is set perpendicular to the edge of the extended section. At the same time, it is ensured that the deflection direction of the translation section is towards the center of the frame. The bottom surface of the hanger body and the bottom surface of the support elbow plate are completely attached to the top surface of the frame. The hanger body and the support elbow plate are firmly welded to the frame using a continuous welding process.

[0032] During the turning operation, the first ear hole of the turning section is connected with a hook or shackle. Since the turning section extends outside the frame, the lifting equipment can be operated freely to achieve safe turning of the frame. During the translation operation, the second ear hole of the translation section is connected with a hook. The tension of the steel cable is along the axis of the translation section, the force is reasonable, the lateral bending moment is avoided, and the smooth and safe translation is ensured.

[0033] The foregoing description illustrates and describes preferred embodiments of the present invention. As previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or related technical or knowledge. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
