Description

Technical Field

[0001] The invention relates to the technical field of road protection, in particular to a self-tensioning anchoring device for a cable guardrail. Background Art

[0002] The cable guardrail self-tensioning anchor device is a system specially designed for road safety facilities. It realizes the adaptive tensioning and fixation of the cable guardrail through high-strength cables, anchors and tensioning devices. The device uses the prestress generated by the tensioning device to keep the cable in a continuous taut state, thereby effectively absorbing and dispersing the impact force during vehicle collision. At the same time, the cable is firmly fixed to the foundation or structure on both sides of the road through anchors, ensuring the stability and protective effectiveness of the guardrail under extreme conditions. This self-tensioning anchor design not only improves the safety performance of the cable guardrail, but also simplifies the installation and maintenance process. It is an important technological innovation in the field of modern road safety protection.

[0003] The core components of existing anchoring devices rely on welding connection technology. However, this technology shows uncertainties in the overall protective effect that cannot be ignored. Specifically, although welding connection can achieve connection between components, there may be many variables in the welding process, such as the selection of welding process parameters, the properties of welding materials, the conditions of the welding environment, etc., which may have a direct impact on the quality of the welded joint. These factors work together to cause potential volatility and inconsistency in the strength, toughness and durability of the welded connection, which in turn affects the overall protective effect of the entire anchoring device. Therefore, the existing welding connection method has certain limitations and uncertainties in providing stable and reliable connection guarantees. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a self-tensioning anchoring device for a cable guardrail, which solves the problem that components of the prior anchoring device are welded connections, resulting in uncertainties in the overall protective effect.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a cable guardrail self-tensioning anchor device, comprising a sleeve, the inner cavity of the sleeve is provided with an engaging thread, the top and bottom of the sleeve are engaged with a cap, a pull rod is passed through the middle of the cap and located at the top of the sleeve, a gasket is sleeved on the outer surface of the pull rod and located in the inner cavity of the sleeve, a spring is sleeved in the middle of the outer surface of the pull rod, the top and bottom of the spring are in contact with the surface of the cap, an anchor core is movably connected to the bottom of the cap on the bottom surface of the sleeve, an anchor is fixedly connected to the bottom of the anchor core, and a connecting thread matched with the sleeve is fixedly connected to the surface of the cap.

[0006] Preferably, a guardrail steel wire rope is fixedly connected to the surface of the anchor, and the anchor is adaptable to guardrail steel wire ropes of various sizes through internal components.

[0007] Preferably, the sleeve, cap, pull rod and anchor are all stainless steel metal structures, and the gasket is a protective gasket made of rubber material.

[0008] Preferably, the surface of the cap is slidably connected to the sleeve, the top of the cap is fixedly connected between the bottom of the sleeve and the spring, and the middle of the top of the cap is fixedly connected between the bottom of the sleeve and the pull rod.

[0009] Preferably, the surface of the cap is slidably connected between the top of the sleeve and the pull rod.

[0010] The present invention provides a self-tensioning anchoring device for a cable guardrail. The sleeve and the connecting component are closely matched through a direct buckle mechanism, which enhances the tensile strength of the connection. When subjected to tension, this structure can effectively reduce the risk of loose connection and ensure the stability of the overall structure. In addition, the connection design also improves the protection performance, can maintain the stability of the connection under harsh environmental conditions, and optimizes the buffering effect, which helps to better absorb and disperse energy when an impact occurs, thereby protecting the connecting component and its supporting structure. In short, the sleeve direct buckle connection method provided by the present invention improves the reliability and safety of the connection, and is suitable for a variety of industrial applications requiring high-strength and stable connections.
