Description

Technical Field

[0001] This application relates to a safety guardrail for dams. Background Technology

[0002] To integrate urban water management and greening, in addition to widening river channels and adding greenery, safety railings are needed in dangerous or steep locations. Current safety railings generally use steel frame structures, which present at least two problems: First, installation is inconvenient on winding riverbanks; second, in case of damage, repairs are usually limited to partial welding or covering, resulting in poor aesthetics and affecting the overall appearance. Utility Model Content

[0003] To address the aforementioned problems, this application proposes a safety guardrail for dams, comprising several opposing support columns, with several flexible connecting rods connecting the support columns. The two ends of each flexible connecting rod are connected to a support column via a hook-and-connection part. Each hook-and-connection part includes a fixed connecting ring connected to the support column, and a sliding sleeve ring movably mounted on the fixed connecting ring. The sliding sleeve ring is connected to the flexible connecting rod via a transverse connecting part. This application employs a combination of a fixed connecting ring and a sliding sleeve ring, which facilitates the fixing of the sliding sleeve ring. Furthermore, the use of flexible connecting rods allows for adjustments based on the position of the support columns, making both initial installation and subsequent maintenance and replacement very convenient.

[0004] Preferably, the fixed connecting ring has two arc-shaped through holes symmetrically arranged relative to the transverse connecting portion, and the sliding sleeve ring has two connecting holes respectively arranged opposite to the arc-shaped through holes. A fixing screw passes through the connecting holes and the arc-shaped through holes. This application, by using a fixing screw passing through the connecting holes and the arc-shaped through holes, allows the upper sliding sleeve ring to rotate around the fixed connecting ring, ensuring structural flexibility and thus guaranteeing reliability during assembly and use.

[0005] Preferably, a plastic buffer ring is provided between the fixed connecting ring and the sliding sleeve ring, and an auxiliary through hole is provided on the plastic buffer ring opposite to the arc-shaped through hole.

[0006] Preferably, the transverse connecting part includes a connecting protrusion connected to a fixed connecting ring, and the connecting protrusion is connected to an outer connecting block by a connecting screw, the outer connecting block being connected to a flexible connecting rod.

[0007] Preferably, the flexible connecting rod includes a silicone tube with side plugs on both sides. A transverse threaded hole is provided on each side plug, and a transverse threaded rod is provided on the side of the outer connecting block, threaded to the transverse threaded hole. This application uses an assembly form of transverse threaded rod and transverse threaded hole, making connection, assembly, and replacement of the flexible connecting rod very simple.

[0008] Preferably, the supporting column includes a column body, a bottom base is provided at the lower part of the column body, and a fixing anchor bolt is provided on the bottom base to be fixedly connected to the foundation.

[0009] Preferably, the inner side of the fixed connecting ring is abutted against and welded to the outer wall of the column body.

[0010] Preferably, the column body is hollow, and a top cover plate is inserted and installed on the top of the column body.

[0011] This application can bring the following beneficial effects: 1. This application adopts a combination of a fixed connecting ring and a sliding sleeve ring, which can easily fix the sliding sleeve ring. As a flexible connecting rod is used, it can be set according to the position of the support column, which is very convenient for both the initial installation and assembly and the later maintenance and replacement.

[0012] 2. By using a fixed screw to pass through the connecting hole and an arc-shaped through hole, this application allows the upper sliding sleeve ring to rotate around the fixed connecting ring, ensuring structural flexibility and thus guaranteeing reliability during assembly and use.

[0013] 3. This application adopts an assembly form of transverse screw and transverse screw hole, which makes the connection, assembly and replacement very simple when assembling the flexible connecting rod. Attached Figure Description
