Description

Technical Field

[0001] This utility model relates to the field of lifting device technology, specifically, to a self-locking spring lifting device for welding onto a hydraulic support structure to provide a lifting position for the hydraulic support structure. Background Technology

[0002] Lifting devices are typically welded to the structural components that need to be lifted, and are used for the lifting and handling of these components. A typical lifting device consists of a sling and a lifting ring. However, the lifting rings of conventional lifting devices are usually vertically downwards under gravity, making it impossible to fix the installation angle. During use, auxiliary operations are usually required to swing the lifting rings upwards to complete the lifting operation between the hook and the lifting ring, affecting lifting efficiency and making it extremely inconvenient to use.

[0003] Currently, few people have raised the aforementioned technical issues, nor has anyone proposed improvements to the lifting device in response to these issues. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a self-locking spring lifting device. This invention ensures normal lifting operations while fully utilizing the self-locking function of the spring's elasticity on the lifting ring, thus guaranteeing the speed of lifting operations.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a self-locking spring lifting device, including a lifting ring and a lifting ring buckle. The lifting ring buckle is welded to the structural component to be lifted, and the lifting ring is rotatably connected in the lifting ring buckle. A spring is tightly pressed between the lifting ring buckle and the lifting ring, and the lifting ring is in tight contact with the structural component under the elastic pressure of the spring to form a self-locking mechanism.

[0006] The top of the inner wall of the lifting ring buckle has a groove, one end of the spring is engaged in the groove, and the other end of the spring presses the lifting ring tightly.

[0007] This invention represents a substantial improvement over existing technologies. Specifically, it utilizes the elasticity of a spring to compress the lifting ring, creating a self-locking mechanism that controls the ring's swing angle, preventing it from swaying downwards. This facilitates lifting operations between the hook and the lifting ring, increasing lifting efficiency and simplifying the process. While ensuring normal lifting operations, this invention fully leverages the spring's self-locking function to guarantee the speed and efficiency of lifting operations.

[0008] The lifting ring buckle of this utility model can be welded onto the hydraulic support structure to provide a lifting position for the hydraulic support structure. Attached Figure Description

[0010] Figure 2 This is a cross-sectional view of the present invention.

[0011] In the diagram: 1. Lifting ring; 2. Lifting ring buckle; 3. Spring; 4. Groove. Detailed Implementation

[0012] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0013] like Figure 1 and Figure 2 As shown, a self-locking spring lifting device includes a lifting ring 1 and a lifting ring buckle 2. The lifting ring buckle 2 is welded to the structural component to be lifted. The lifting ring 1 is rotatably connected in the lifting ring buckle 2. A spring 3 is tightly pressed between the lifting ring buckle 2 and the lifting ring 1. Under the elastic pressure of the spring 3, the lifting ring 1 is tightly pressed into contact with the structural component to form a self-locking mechanism.

[0014] A groove 4 is provided on the top of the inner wall of the ring buckle 2. One end of the spring 3 is engaged in the groove 4, and the other end of the spring 3 presses tightly against the ring 1. The optimal design is that the groove 4 is located at the center of the top of the inner wall of the ring buckle 2.

[0015] This embodiment is used for the hoisting of hydraulic support structural components. In use, the lifting ring 2 is welded to the hydraulic support structural component, and the spring 3 can press the lifting ring 1 to make the lifting ring 1 self-locking, thereby controlling the swing angle of the lifting ring 1, preventing the lifting ring 1 from swinging down, which is beneficial to the hoisting operation of the hook and the lifting ring 1, improving hoisting efficiency and making hoisting convenient.

[0016] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
