Description

Technical Field

[0001] This utility model relates to the field of lifeline fixing ring technology, specifically to a reusable lifeline pre-embedded fixing ring. Background Technology

[0002] Lifelines, as an indispensable safety barrier in high-altitude operations and construction, play a crucial role in ensuring the safety of workers. These safety ropes are meticulously crafted from high-quality flexible materials such as steel wire rope, high-strength fiber rope, or specialized webbing, with a tensile strength generally not less than 30KN, sufficient to effectively prevent falls in emergencies and provide a solid safety guarantee for workers at heights. However, the effectiveness and safety performance of lifelines depend not only on their materials and design but also on their installation and fixing methods. In existing technology, a common practice is to directly embed the fixing rings into the wall structure to ensure a stable installation of the lifeline. While this method meets the fixing requirements to some extent, its limitations have gradually become apparent in practical applications. In particular, once the pre-embedded fixing rings are installed, they are difficult to recover and reuse, resulting in significant resource waste and increased construction costs. Furthermore, the structure of the pre-embedded fixing rings often creates protrusions on the wall surface, affecting the overall flatness of the wall and causing numerous inconveniences for subsequent decoration and use. Utility Model Content

[0003] To overcome the above deficiencies, this utility model provides a reusable lifeline pre-embedded fixing ring to solve the aforementioned problems.

[0004] This utility model is implemented as follows:

[0005] A reusable lifeline pre-embedded fixing ring includes an embedded part, an assembly plate, and a lifting assembly. Several anchor rods are provided on the rear side of the embedded part. Right-angle plates a and b are bolted to the front side of the embedded part, with right-angle plate a positioned above right-angle plate b. A clamping plate is movably mounted on right-angle plate a. The assembly plate is fixed between right-angle plates a and b via the clamping plate. The lifting assembly is hinged to the front side of the assembly plate. A lifting ring is movably mounted at the bottom of the lifting assembly. The lifting ring swings back and forth and rotates left and right under the influence of the connected lifeline.

[0006] In an embodiment of this utility model, a surrounding plate is provided on the top of the right-angle plate b, an embedding groove is formed between the surrounding plate and the embedded part, and the bottom of the assembly plate is embedded in the embedding groove.

[0007] In an embodiment of this utility model, the clamping plate includes a screw and an L-shaped clamping plate. The screw is threadedly connected to the right-angle plate a. A movable hole is provided at the top center of the L-shaped clamping plate. A limiting hole is provided on the side wall of the movable hole. The screw passes through the movable hole and a limiting flange is provided on the side near the limiting hole.

[0008] In an embodiment of this utility model, the hoisting assembly includes two symmetrically arranged side plates, a hollow connecting part is provided between the two side plates near the top, and an installation block is also provided between the two side plates, with the lifting ring movably disposed in the installation block.

[0009] In an embodiment of this utility model, the lifting ring passes through the bottom center of the mounting block, and a collar is fitted on the protruding part. The lifting assembly also includes a pin, which passes through the collar and the lifting ring sequentially from the outside of the collar.

[0010] In an embodiment of this utility model, ear plates are symmetrically arranged at the two front edges of the assembly plate.

[0011] In an embodiment of this utility model, the hoisting assembly is disposed between the two ear plates, and a connecting shaft is movably disposed within the connecting part. The two sides of the connecting shaft pass through the ear plates and are fixed by nuts.

[0012] In an embodiment of this utility model, swing grooves are provided on opposite sides of the two ear plates, and the swing grooves limit the swing of the hoisting assembly in the front-to-back direction to less than or equal to 30 degrees.

[0013] The beneficial effects of this utility model are as follows: This utility model first pre-embeds the embedded parts into the wall, so that the front side of the embedded parts is coplanar with the wall, ensuring that the flatness of the wall surface will not be affected when it is subsequently removed. At the same time, the modular assembly plate and hoisting components are adopted, so that each part can be manufactured independently and flexibly combined, which greatly improves the convenience of production and installation. This modular design also facilitates subsequent disassembly and recycling, reduces maintenance costs, and realizes the effective use of resources. Furthermore, the movable design of the lifting ring allows it to swing and rotate within a certain range, effectively reducing the friction and impact between the lifeline and the lifting ring, and reducing the risk of breakage caused by friction.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] like Figure 1As shown, this utility model provides a reusable lifeline pre-embedded fixing ring, including a pre-embedded part, an assembly plate, and a hoisting assembly. Several anchor rods are provided on the rear side of the pre-embedded part. The pre-embedded part is pre-installed inside the wall, making its front side flush with the wall surface. Further, right-angle plates a and b are bolted to the front side of the pre-embedded part, with right-angle plate a positioned above right-angle plate b. A clamping plate is movably mounted on right-angle plate a, allowing the assembly plate to be fixed between right-angle plates a and b via the clamping plate. The hoisting assembly is hinged to the front side of the assembly plate, and a lifting ring is movably mounted at the bottom of the hoisting assembly. The lifting ring swings back and forth and rotates left and right under the influence of the connected lifeline. This movable lifting ring allows for small-range movement as the lifeline swings during use, reducing friction between the lifeline and the lifting ring and improving safety. Furthermore, this fixing ring is easy to install and remove. When completely removed, the remaining pre-embedded part is flush with the wall, without affecting subsequent use.

[0023] In this embodiment, a surrounding plate is provided on the top of the right-angle plate b, and an embedding groove is formed between the surrounding plate and the embedded part. The bottom of the assembly plate is embedded in the embedding groove.

[0024] like Figure 2 As shown, the clamping plate includes a screw and an L-shaped clamping plate. The screw is threadedly connected to the right-angle plate a. A movable hole is provided at the top center of the L-shaped clamping plate. A limiting hole is provided on the side wall of the movable hole. The screw passes through the movable hole and a limiting flange is provided on the side near the limiting hole, so that the screw and the L-shaped clamping plate form a movable connection relationship. By rotating the screw, the L-shaped clamping plate is pushed to clamp the top of the assembly plate.

[0025] like Figure 3 As shown, the hoisting assembly includes two symmetrically arranged side plates, a hollow connecting part is provided between the two side plates near the top, and an installation block is also provided between the two side plates, with the lifting ring movably set in the installation block.

[0026] like Figure 4 As shown, the lifting ring passes through the bottom center of the mounting block, and the protruding part is fitted with a collar. The lifting assembly also includes a pin, which passes through the collar and the lifting ring sequentially from the outside of the collar.

[0027] In this embodiment, ear plates are symmetrically arranged on the two front edges of the assembly plate, the hoisting component is arranged between the two ear plates, and a connecting shaft is movably arranged in the connecting part. The two sides of the connecting shaft pass through the ear plates and are fixed by nuts.

[0028] In a preferred embodiment, the two ear plates are provided with swing grooves on opposite sides. When the hoisting assembly moves in the front-back direction of the swing groove, it abuts against the side wall of the swing groove, so that the swing groove limits the swing of the hoisting assembly in the front-back direction to less than or equal to 30 degrees.

[0029] Specifically, the working principle of this reusable lifeline pre-embedded fixing ring is as follows: First, the pre-embedded part is pre-set into the wall, ensuring that the front side of the pre-embedded part is coplanar with the wall, guaranteeing that the flatness of the wall surface will not be affected during subsequent removal. Simultaneously, several threaded holes are provided on the front side of the pre-embedded part. Based on these holes, right-angle plate a, right-angle plate b, and a clamping plate are installed. These three parts form a clamping component for clamping and fixing the assembly plate. Fixing and loosening this clamping component can be accomplished simply by rotating a screw. Furthermore, the hinged relationship between the hoisting assembly and the assembly plate allows for hoisting... The movable connection between the lifting ring and the mounting block in the component ensures that the lifting ring can move within a certain angle range. That is, when subjected to the swaying of the lifeline, it can move at a certain angle with its swing amplitude, thereby reducing the impact on the lifting ring on the device, reducing the friction between the lifeline and the lifting ring, and improving safety. Through the above structure, the problems of the existing technology of pre-embedded installation of lifting rings, which are difficult to recycle and reuse, causing waste of resources and increasing construction costs, as well as the problems of the protrusion formed on the wall affecting the overall flatness of the wall and affecting subsequent decoration and applicability, are solved.

[0030] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
