Description

Technical Field

[0001] This utility model relates to the technical field of hoisting equipment for metallurgical products, and more specifically, to a hoisting tool and buffer protection device for anti-scratch steel coils. Background Technology

[0002] In the steel production, storage, and logistics processes, the lifting of steel coils (such as hot-rolled coils, cold-rolled coils, galvanized coils, and color-coated coils) is a frequent and critical operation. Traditional steel coil lifting mainly uses C-type lifting tools, horizontal coil lifting tools, or electromagnetic lifting tools.

[0003] The booms, hooks, or contact surfaces of these lifting devices are mostly made of metal, which presents significant defects during lifting operations.

[0004] Based on the above, the inventors have discovered that currently, the metal parts of the lifting device directly contact the inner diameter (inner hole of the coil) or end face of the steel coil. During lifting, moving, aligning, and placing, even slight slippage, shaking, or compression can easily leave scratches, indentations, or abrasions on the surface of the steel coil (especially the plated or coated surface), severely affecting the product's appearance and value. The impact generated when the lifting device contacts the steel coil or when the coil shakes is difficult to effectively buffer, even with simple pads on the contact surface, potentially leading to localized coating peeling or substrate deformation. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a scratch-resistant steel coil lifting device and buffer protection device, aiming to achieve a more practical purpose.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A scratch-resistant steel coil lifting device and buffer protection device includes a main rod and a lifting ring. The lifting ring is threaded to the top of the main rod. A vertical plate is threaded to the bottom of the main rod. A connecting seat is bolted to the bottom of the vertical plate. Conical seats are installed at the lower left and lower right corners of the vertical plate. A base plate is fixedly connected to the bottom of the connecting seat. An mounting seat is installed at the connection between the base plate and the conical seat. An arc-shaped seat is fixedly connected to the bottom of the conical seat. A buffer protection component is installed below the arc-shaped seat. An arc-shaped sleeve is fixedly provided on the inner side wall of the arc-shaped seat. A threaded groove is formed on the outer side wall of the arc-shaped seat.

[0010] Furthermore, the upper and lower parts of the main rod are respectively provided with external thread one and external thread two, and an installation sleeve is fixedly provided below the lifting ring. The inner side wall of the installation sleeve is provided with internal thread one, and internal thread one is threadedly connected to external thread one.

[0011] Furthermore, a fixing sleeve is fixedly provided at the upper middle position of the upright plate, and the inner side wall of the fixing sleeve is provided with an internal thread two, which is threadedly connected to the external thread two.

[0012] Furthermore, the buffer protection assembly includes a fixed base fixedly connected to the bottom of the arc-shaped seat, an adjusting rod threadedly connected to the inner side of the fixed base, an arc-shaped pad fixedly connected to one side of the adjusting rod, and an installation frame installed on the outer side of the fixed base, with a limit rod threadedly connected to one side of the installation frame.

[0013] Furthermore, the arc-shaped pad is made of rubber material, the outer wall of the mounting frame is provided with a second threaded groove, and the limiting rod passes through the mounting frame and is threadedly connected to the first threaded groove on the arc-shaped seat.

[0014] Furthermore, a steel coil is installed below the buffer protection assembly, and a steel coil body is provided on the outer side of the steel coil. The buffer protection assembly is provided in two sets, symmetrically arranged on both sides of the steel coil.

[0015] Furthermore, the two sides of the conical seat are connected to the vertical plate and the arc-shaped seat respectively via movable shaft one and movable shaft two.

[0016] 3. Beneficial effects

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] (1) This solution achieves full-wrap, non-damaging clamping of the outer surface of the steel coil by setting up a flexible clamping structure consisting of an arc-shaped seat and an arc-shaped sleeve. During the hoisting process, the two arc-shaped seats move inward synchronously under the drive of the four-bar linkage mechanism. The arc-shaped sleeve on the inner side is made of flexible material (rubber) and can completely fit the outer surface of the steel coil. This clamping method avoids the traditional method of inserting the lifting tool into the inner diameter of the steel coil or using metal hooks, and completely eliminates the direct contact between the metal parts and the surface of the steel coil. The flexible material arc-shaped sleeve can effectively disperse the clamping force, absorb vibration and impact, and prevent indentations, scratches or coating peeling caused by stress concentration. It achieves true "anti-scratch" hoisting, and is especially suitable for coated or plated steel coils with extremely high surface quality requirements.

[0019] (2) This solution achieves stable, reliable, and adjustable hoisting operations by setting up a four-bar parallel lifting mechanism (consisting of a vertical plate, a conical seat, a movable shaft one, a movable shaft two, and an arc-shaped seat) and an adjustable buffer protection assembly. The four-bar mechanism ensures that the arc-shaped seats on both sides remain parallel during the lifting process, allowing the arc-shaped clamps to clamp or release the steel coil evenly and synchronously, avoiding tilting or rolling of the steel coil caused by unilateral force. The arc-shaped pad and adjusting rod in the buffer protection assembly provide additional support and cushioning at the bottom of the steel coil. The threaded design of the adjusting rod allows for fine adjustment of the distance between the arc-shaped pad and the main body of the steel coil to accommodate steel coils of different diameters and ensure uniform support force. The limit rod ensures the stability of the buffer protection assembly during operation. This design not only improves the safety and stability of hoisting but also enhances the versatility of the device through structural adjustability, making it suitable for hoisting steel coils of various specifications.

An arc-shaped sleeve 13 is fixedly provided on the inner side wall of the arc-shaped seat 6. A threaded groove 10 is opened on the outer side wall of the arc-shaped seat 6.

[0030] See Figure 1 and Figure 3 The main rod 1 has an external thread 1 and an external thread 2 respectively on its upper and lower parts. An installation sleeve is fixedly installed below the lifting ring 11. An internal thread 1 is provided on the inner side wall of the installation sleeve. The internal thread 1 is threadedly connected to the external thread 1. The internal thread 1 and the external thread 1 are used to assemble and disassemble the lifting ring 11.

[0031] See Figure 1 and Figure 3 A fixing sleeve is fixedly installed at the middle position above the upright plate 2. The inner side wall of the fixing sleeve is provided with an internal thread 2, which is threadedly connected to an external thread 2. The internal thread 2 and the external thread 2 are used for disassembling and assembling the main rod 1.
