Description

Technical Field

[0001] This utility model relates to the field of corrugated plate transfer lifting tools, and more specifically, to a lifting tool for lifting corrugated plates. Background Technology

[0002] Corrugated steel sheet is a new type of decorative material, featuring a smooth, three-dimensional shape and a variety of vibrant colors. It is poised to become a mainstream decorative material leading fashion trends and creating beautiful living spaces, representing a next-generation product in the decorative materials industry. Our products, including plain sheets, pure white sheets, colored sheets, and gold / silver foil sheets, boast beautiful shapes, exquisite craftsmanship, elegant appearance, uniform structure, dimensional stability, and a strong three-dimensional effect. We also offer custom-made corrugated steel sheets with different patterns, colors, and shapes according to customer requirements. Furthermore, we process various thicknesses and specifications of stainless steel and titanium alloy grooves (corner trims) and semi-circular edges (commonly known as "edging"), suitable for indoor and outdoor light boxes, advertising signs, edge sealing, door clamps, etc.

[0003] After the corrugated sheets are manufactured, they need to be hoisted onto transport vehicles to be delivered to various sales points. However, due to the unique corrugated shape of the sheets, the hoisting difficulty is increased. It is difficult to control the position of the sheets during hoisting. When they are hoisted to a certain height, they are prone to tilting and falling, which can cause serious damage to the sheets, resulting in economic losses and posing a great safety hazard.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.

[0020] Example This utility model provides a lifting tool for hoisting corrugated plates, such as... Figures 1-3As shown, the device includes a lifting mechanism comprising two paired lifting bodies 4. Each lifting body 4 has an upper limit rod 5 rotatably mounted on one side, and a lower limit rod 6 mounted on the other side. The upper limit rod 5, the lifting body 4, and the lower limit rod 6, when joined together, form a clamping area. Both the upper limit rod 5 and the lower limit rod 6 are arc-shaped rods. When the clamping area formed by the upper limit rod 5, rotatably mounted on the lifting body 4, and the lower limit rod 6, fixed to the lifting body 4, clamps both sides of the corrugated plate, the clamping area has a C-shaped structure. The C-shaped structure covering the edge of the corrugated plate prevents slippage during lifting. The double lifting system balances the load, reduces the risk of off-center loading, and improves stability. Furthermore, the open ends of the two clamping areas are positioned opposite each other, facilitating operation. A lifting abutment is mounted at the other end of the lifting body 4. This lifting abutment is annular and welded to the side wall of the lifting body 4. Each lifting device body 4 is equipped with a control structure for controlling the movement of the upper limit rod 5 relative to the lower limit rod 6. The control structure is a rotating shaft 13 integrally formed with the lifting device body 4, mounted on the rotating shaft 13. The upper limit rod 5 is rotatably mounted on the rotating shaft 13, and a torsion spring 14 connected to the upper limit rod 5 is mounted on the rotating shaft 13. The torsion spring 14 facilitates the automatic reset of the upper limit rod 5; when the external force is removed, the upper limit rod 5 automatically returns to its clamped position. This design allows the structure to automatically lock during lifting and easily open during release, improving efficiency and reducing manual operation steps.

[0021] It also includes a lifting rope 1, whose two free ends are detachably connected to two lifting attachment points. This facilitates the operator in attaching the above structure to the lifting equipment. The lifting equipment is typically an electric chain hoist or a crane.

[0022] Preferably, there are two sets of lifting ropes 1, which can improve the load-bearing capacity during lifting. A stabilizing frame 2 is also installed between the two lifting ropes 1, and a lifting ring 3 is integrally formed on the stabilizing frame 2 to ensure stability during the lifting process.

[0023] In some technical solutions of this utility model, a lifting frame 9 is also included. A boom 10 is installed on both sides of the lifting frame 9. Two lifting attachments are detachably connected to the two booms 10, and both ends of the lifting rope 1 are connected to the lifting frame 9. The lifting frame 9 serves as an integral support structure, distributing the force. The detachable connection between the lifting attachments and the booms 10 via bolts facilitates later adjustment and maintenance.

[0024] In some technical solutions of this utility model, the number of lifting mechanisms is two sets, and the two sets of lifting mechanisms are respectively installed on both sides of the boom 10 with the extension direction of the main body of the lifting frame as the axis of symmetry. The two sets of lifting mechanisms are installed symmetrically, and the symmetrical structure can balance the force, prevent unilateral overload, improve stability, and is especially safer when lifting large objects.

[0025] In some technical solutions of this utility model, two displacement frames 8 are slidably provided on the lifting frame 9, and the two displacement frames 8 are respectively fixedly connected to two booms 10. The lifting frame 9 and the displacement frames 8 are detachably connected.

[0026] The lifting frame 9 houses two push rod structures 11, each corresponding to a displacement frame 8. The body of each push rod structure 11 is connected to the lifting frame 9, and both the telescopic ends of the push rod structures 11 are connected to their corresponding displacement frames 8. The relative position of the boom 10 is adjusted by the combined action of the displacement frames 8 and the push rod structures 11 to accommodate corrugated plates of different sizes, increasing the lifting device's applicability and flexibility. The push rod structures 11 are driven by either electro-hydraulic rods or a complementary hydraulic rod system, enabling automatic position adjustment and improving efficiency.

[0027] In some technical solutions of this utility model, a bevel 7 is provided on the end face of the lower limit rod 6 opposite to the upper limit rod 5. The bevel 7 design of the lower limit rod 6 makes guiding the corrugated plate into the clamping area smoother, reduces friction or alignment difficulties, and makes operation less strenuous. The bevel 7 also aids in guidance, reduces adjustment time, and improves work efficiency.

[0028] In some technical solutions of this utility model, a stabilizing rod 12 is installed between the lower limit rods 6 located in the two sets of lifting mechanisms. Connecting the lower limit rods 6 located in the two lifting structures with the stabilizing rod 12 can enhance the structural rigidity, prevent deformation, and ensure stability during clamping.

[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
