Description

Technical Field

[0001] The invention relates to the field of lifting rings, in particular to a lifting ring that can be used for lifting ears of different sizes. Background Art

[0002] The wire ropes used in daily lifting of rollers for assembly are not durable. Multiple sets of wire rope slings are consumed every month, resulting in great waste. After long-term use, the wire buckles are deformed, making them difficult to use in the later stage. The lifting chains are not easy to remove and cannot be reliably fixed.

[0003] Therefore, it is necessary to develop a new type of lifting ring to overcome the above problems. Summary of the invention

[0004] Purpose of the invention: In view of the shortcomings and defects of the prior art, the present invention provides a lifting ring that can be used for lifting ears of different sizes. The bearing seat has two types of lifting ears, and the lifting of the bearing seat assembly with different types of lifting ears can be completed without changing the lifting equipment. It is not easy to deform during use, and is provided with an anti-slip design to prevent the hoisted object from being unhooked during the lifting process.

[0005] Technical solution: The present invention is a lifting ring that can be used for lifting ears of different sizes, characterized in that it includes a stepped shaft and a lifting ring body that are connected to each other, the lifting ring body is connected to an external shackle through the stepped shaft, and the stepped shaft is provided with a shackle mounting hole for the shackle; the lifting ring body is provided with corresponding hole types according to different lifting ears, and switching can be performed by rotating the lifting ring body 180°.

[0006] Wherein, the stepped shaft and the lifting ring body are connected by welding.

[0007] Wherein, the lifting ring body is made of Q235 or above structural steel.

[0008] Wherein, the lower half of the lifting ring body is an arc groove structure.

[0009] Wherein, the shackle is connected with a one-ring four-leg lifting chain.

[0010] Wherein, the outer edge of the lifting ear is inserted into the lifting ring body, and under the action of gravity, the lifting ear is stuck in the upper part of the lifting ring body.

[0011] During the lifting process, the lifting lug slides automatically to the lower part of the lifting ring body, locking the lifting lug to prevent it from falling off during the lifting process.

[0012] During preparation, steel plates with strength not less than Q235 are selected for cutting; the machine tool processes the required hole type; the workpiece is bent into the required shape; the required shackle mounting hole is drilled; the stepped shaft is turned; the stepped shaft is drilled; and the lifting ring is assembled.

[0013] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: The present invention aims to reduce the use cost of the sling during lifting and extend its service life, while ensuring the reliability of the lifting process and preventing the objects from falling off. A rigid lifting ring is designed, which is not easily deformed during use and is provided with an anti-drop design to prevent the objects from falling off during lifting.

[0021] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0022] The lifting ring of the present invention, which can be used for lifting ears of different sizes, comprises a step shaft 1 and a lifting ring body 3 connected to each other. The lifting ring body 3 is connected to an external shackle through the step shaft 1. The step shaft 1 is provided with a shackle mounting hole 2 for the shackle. The lifting ring body 3 is provided with corresponding hole types according to different lifting ears. When switching, the lifting ring body 3 can be rotated 180°. Among them, the step shaft 1 and the lifting ring body 3 are connected by welding. The lifting ring body 3 is made of Q235 or above structural steel. The lower half of the lifting ring body 3 is an arc groove structure. The shackle is connected to a one-ring four-leg lifting chain. The outer edge of the lifting ear is inserted into the lifting ring body 3, and under the action of gravity, the lifting ear is stuck in the upper half of the lifting ring body 3. During the lifting process, the lifting ear slides to the lower half of the lifting ring body 3 by itself, locking the lifting ear to prevent it from falling off during the lifting process.

[0023] When preparing the lifting ring that can be used for lifting ears of different sizes, the steel plate with strength not less than Q235 is selected for blanking; the machine tool processes the required hole type; the workpiece is bent into the required shape; the required shackle mounting hole 2 is drilled; the step shaft 1 is turned; the step shaft 1 is drilled; and the lifting ring is assembled.

[0024] Compared with the wire rope hoist ring, the invention is more durable, not easy to deform after long-term use, and easy to install. The hoist is connected to the one-ring four-leg hoist chain through a shackle, which is more durable than the one-ring four-leg wire rope hoist. At the same time, the arc groove is designed at the lower part of the hoist ring, which is difficult to fall off during the hoisting process and is safer.
