Description

Technical Field

[0001] The utility model relates to the technical field of mechanical devices, in particular to a rotating lifting ring. Background Art

[0002] Lifting rings are usually located on the upper part of industrial machinery. By connecting to the slings of lifting equipment (such as cranes or hoists), industrial machinery can be lifted and moved smoothly. At construction sites, industrial machinery often needs to be moved from one location to another. Lifting rings make this process simple and quick. During the use of industrial machinery, it may be necessary to install or disassemble it. Lifting rings provide convenience for these operations. Reasonable design of lifting rings can ensure the stability of industrial machinery during the lifting process and reduce the risk of safety accidents caused by improper operation.

[0003] The publication number is: CN207511668U, which discloses a lifting ring that can realize the operation of discarding heavy objects, including a lifting ear and a lifting ear seat connected to the lifting ear, the middle part of the lifting ear seat is provided with a lifting ear seat hole, the lifting ear seat hole is a through hole, and a lifting screw is provided in the lifting ear seat hole, and the lifting screw comprises an inverted truncated cone, the upper part of the truncated cone is provided with an upper step, the upper step is provided with an external hexagonal bolt head, the lower part of the truncated cone is provided with a lower step, and the lower end of the lower step is provided with a threaded column. It is easy to replace during use, and only the lifting screws with threaded columns of different specifications need to be replaced to achieve the effect of one lifting ear matching multiple sizes. However, when this technology is installed on a workpiece, there is a contradiction between the direction of the lifting ear and the direction of force, and the force direction is inconsistent with the direction of the lifting ear, which may cause the hoisted object to tilt or rotate during the lifting process, resulting in unstable lifting and increased safety risks. Therefore, there is still room for modification of the technology. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a rotating lifting ring in view of the deficiencies of the above-mentioned prior art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a rotating lifting ring, including a lifting ear and a lifting ear seat, wherein the lifting ear is movably connected to the lifting ear seat, and the lifting ear seat is provided with a lifting seat hole. The characteristic is that the lifting ear is provided with a connecting seat, and the connecting seat is rotatably connected to the lifting ear seat by setting a horizontal rotating structure.

[0006] By adopting the above technical solution, the lifting ear is connected to the lifting ear seat through the horizontal rotating structure provided on the connecting seat, so that the connecting seat drives the lifting ear to rotate horizontally through the horizontal rotating structure. The lifting ear can rotate horizontally along the direction of the force applied by the industrial machine, so that the direction of the lifting ear will not conflict with the force direction of the lifting ear, and the lifting of the connected industrial machine is more stable.

[0007] The above-mentioned rotating lifting ring can be further configured as follows: the horizontal rotating structure includes a connecting hole arranged on the lifting ear seat, the bottom end of the lifting ear seat is provided with a contact groove, the contact groove is communicated with the connecting hole, the bottom end of the connecting seat is provided with a contact surface, the connecting seat is penetrated into the connecting hole to promote the contact between the contact surface and the contact groove, and the diameter of the contact groove is larger than the diameter of the connecting hole.

[0011] The above-mentioned rotating lifting ring can be further configured as follows: the connecting portion includes a sleeve hole arranged at the center of the rolling structure, and the rolling structure is sleeved on the connecting seat through the sleeve hole and abuts against the abutment surface.

[0012] By adopting the above technical solution, the rolling structure is sleeved on the abutment surface, so that one end of the rolling structure abuts against the abutment groove and the other end abuts against the abutment surface. The setting of the rolling structure greatly reduces the friction between the abutment groove and the abutment surface, making the rotation of the hanging ring smoother.

[0013] The above-mentioned rotating lifting ring can be further configured as follows: the rolling structure includes an upper shell, a lower shell, an inner ring, and rollers, and the plurality of rollers are embedded between the upper shell and the lower shell through the inner ring.

[0014] By adopting the above technical solution, the inner ring embeds the roller between the upper shell and the lower shell, so that the upper shell and the lower shell can rotate. The upper shell and the lower shell are sleeved on the connecting seat, the lower shell abuts against the abutment surface, and the upper shell abuts against the abutment groove, thereby reducing the friction between the abutment surface and the abutment groove.

[0015] The above-mentioned rotating lifting ring can be further configured as follows: the lifting seat hole is arranged around the lifting ear seat.

[0016] By adopting the above technical solution, at least two hanging seat holes are arranged around the lifting ear seat. Since the lifting ring is often used in heavy industrial machinery, the lifting ring needs to be tightly connected with the industrial machinery. The setting of several hanging seat holes greatly increases the tightness between the lifting ring and the industrial machinery, ensuring the stability and safety of industrial production.

[0017] The above-mentioned rotating lifting ring can be further configured as follows: the abutting groove, the abutting surface, the connecting hole and the connecting seat are all circular.

[0018] By adopting the above technical solution, the abutment groove, abutment surface, connection hole, connection seat and other parts that drive the lifting ring to rotate are all arranged in a circular shape, so that the rotation of the lifting ring is unobstructed and the rotation of the lifting ring is convenient.

[0019] The above-mentioned rotating lifting ring can be further configured as follows: a connecting column is further provided between the lifting ear and the connecting seat.

[0020] By adopting the above technical solution, the existing lifting ring directly connects the two ends of the lifting ear to the lifting ear seat, and the connection surface is small, which is prone to breakage when connected to heavy industrial machinery. A connecting column is set between the lifting ear and the connecting seat to increase the connection area of ​​the lifting ear and make the connection of the lifting ear more stable.

[0021] The beneficial effects of the utility model are as follows: the lifting ear is passed through the connecting seat and the connecting hole, the abutting surface at the bottom of the connecting seat abuts with the abutting groove at the bottom of the lifting ear seat, and the bottom abutting setting enables the connecting seat to rotate in the connecting hole, so that the direction of the lifting ear changes with the force direction, and will not conflict with the force direction of the lifting ear, making the lifting more stable.
