Description

Technical Field

[0001] The invention relates to the technical field of mechanical manufacturing, and in particular to a rotary lifting adjustable lifting ear structure and a use method thereof. Background Art

[0002] With the continuous improvement and popularization of automation and leanness in the mechanical manufacturing process, the production process requires that the tooling and auxiliary tools should meet the conditions for the use of automated equipment and minimize the space required for storage and transportation. However, heavy tooling and auxiliary tools need to be designed with lifting lugs for lifting. Figures 1 to 3 The existing lifting lug structures are all cast or welded fixed structure lifting lugs. In order to facilitate the hanging of steel cables or hooks, the lifting lug design needs to reserve operating space, which makes the lifting lug itself high, which is easy to interfere with equipment, parts, etc., and also requires more space during storage or transportation. Summary of the invention

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the defects in the prior art that the lifting ear itself is relatively high, easily interferes with equipment, parts, etc., and occupies a large space, thereby providing a rotating and lifting adjustable lifting ear structure and a method of use.

[0005] There are two fixed side support walls, and grooves are provided on the two adjacent sides of the two fixed side support walls. The first limiting mechanism is provided on the inner wall of the two fixed side support walls away from the groove. The rotating side support wall is provided on the inner wall of the two fixed side support walls close to the groove. The bottom surface of the rotating side support wall is in contact with the first limiting mechanism, and the bottom surface of the rotating side support wall is a smooth curved surface. The side of the first limiting mechanism in contact with the bottom surface of the rotating side support wall is a plane. The rotating side support wall is connected to the fixed side support wall through the connecting mechanism. The lifting rod passes through the two rotating side support walls and is connected with the groove on the fixed side support wall. The lifting rod is provided with a second limiting mechanism.

[0006] Furthermore, the first limiting mechanism is a limiting baffle.

[0007] Furthermore, the lifting rod is provided with a circle of grooves, and the second limiting mechanism is cooperatively connected with the grooves.

[0008] Furthermore, the second limiting mechanism is a gravity limiting ring.

[0009] Furthermore, the diameter of the gravity limiting ring is the same as the diameter of the lifting rod.

[0010] Furthermore, the lifting rod is provided with a thread which is threadably connected to the rotating side support wall.

[0011] Furthermore, the connecting mechanism is a pin.

[0012] Furthermore, the connection mechanism is a semi-threaded bolt, and the threaded portion is cooperatively connected with a nut.

[0013] Furthermore, a connecting rod is provided between the two rotating side supporting walls.

[0014] A method for using a rotating and lifting adjustable lifting ear structure based on any of the above items, characterized in that when the lifting ear structure is converted from a production or storage and transportation state to a lifting state, the following operations are required: first, straighten the gravity limit ring and pull the lifting rod out of the rotating side support wall, then rotate the rotating side support wall with the connecting mechanism as the axis to the lifting state until the side surface is in contact with the first limit mechanism for limit, then straighten the gravity limit ring and insert the lifting rod into the rotating side support wall, release the gravity limit and let it droop by its own weight to form a limit.

[0015] The lifting ear structure of the present invention can change the height of the lifting rod from the ground and the overall height of the lifting ear by rotation. In the non-lifting state, the lifting ear can be rotated and folded to the lowest height to avoid interference with other objects during use, and can also save storage space and facilitate storage and transportation.
