Embodiment 1

[0081] like Figure 1-2 As shown, a spring yield type energy dissipator used for slope flexible protection system, the energy dissipator consists of a spring steel (1), a rotating shaft (2), a pin shaft (3 ), a C-shaped clamp (4) and a curved lug (5). The spring steel (1) is mechanically rolled from square steel around the rotating shaft (2), one end of the spring steel (1) is welded on the rotating shaft (2), and the other end is tightly wound around the rotating shaft (2) for several turns before it rotates The shaft (2) protrudes tangentially for a certain length, and the protruding end is provided with a first connection hole (9) connected to the first support rope (6) of the flexible protection system;

[0082] The rotating shaft (2) has a built-in pin shaft (3) and can rotate around the pin shaft (3). The two ends of the pin shaft (3) are connected to the C-shaped clamp (4) through bolts (11). The ear plate (5) is welded and fixed, and the arc-shaped ear plate (5) is c...

Embodiment 2

[0105] like image 3 As shown, a combination and design method of a spring yield type energy dissipator for a slope flexible protection system, the energy dissipator includes 3 spring steels (1), 3 rotating shafts (2) when used in combination according to this embodiment ), 3 pin shafts (3), 1 C-shaped clamp (4) and 1 arc ear plate (5).

[0106] like image 3 As shown, when using the energy dissipator in combination according to this embodiment, three main structures of the energy dissipator when used alone are formed according to the method in embodiment 1, and arranged in a certain way to form the energy dissipator when used in combination according to this embodiment. The main structure of the energy device.

[0107] When using this energy dissipator in combination according to this embodiment, the clamp flange plate (13) of the C-shaped clamp (4) in Embodiment 1 is replaced with a triangle, and each clamp flange plate (13) reserves 3 clamp connections holes (14), and re...

Abstract

The invention discloses a spring-type yielding energy dissipator and a design method for a slope flexible protection system. The energy dissipator includes spring steel, a rotating shaft, a pin shaft, a C-shaped clamp, and an arc-shaped ear plate. Among them, the spring steel is tightly wound on the rotating shaft, and at the same time, one end with a hole extends a distance along the tangential direction of the rotating shaft and is connected to the support rope of the flexible protection system through the hole, and the other end is welded to the rotating shaft. The rotating shaft is sleeved with a pin shaft with a small gap. The pin shaft is connected to the upper and lower clamp flange plates of the C-shaped clamp through bolts. The web of the C-shaped clamp is welded with arc-shaped lugs, and the reserved holes in the lugs are connected to the other side of the flexible protection system. A support rope is attached. When the flexible protection system is impacted, the spring steel connected to the support rope is pulled and rotated around the axis of rotation, changing from a bent state to a straight state, consuming energy through its plastic deformation. After the impact is over, the spring steel can be coiled around the axis of rotation into a spring shape from a straightened state to achieve repeated use. The energy dissipation device of the invention has reasonable structural design, clear energy dissipation mechanism, strong energy dissipation capability, convenient disassembly, assembly and maintenance, suitable for installation in a narrow space, and can be used repeatedly.

Description

technical field [0001] The invention relates to a spring type yield type energy dissipator used in a slope flexible protection system and a design method, belonging to the field of slope geological disaster protection. Background technique [0002] The prevention and control of slope geological disasters is one of the most important problems in the field of civil engineering in my country, especially in projects along highways and railways, frequent disasters such as collapses, rockfalls, landslides, and debris flows have seriously endangered people's lives and property Safety. Traditional protection measures such as rigid rock dams have high requirements on the terrain and have limitations. The flexible protection system is light, high-strength and easy to install. It is suitable for various terrains and has been widely used in the prevention and control of disasters such as collapses, rockfalls, landslides, and debris flows. middle. The flexible protection system is compo...
