Embodiment 1

[0081] Such as 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) i...

Embodiment 2

[0105] Such as 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] Such as 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), ...

Abstract

The invention discloses a spring yield type energy dissipator for a slope flexible protection system and a design method. The energy dissipator comprises spring steel, a rotating shaft, a pin shaft, aC-shaped clamp and an arc-shaped lug plate. The spring steel is tightly wound on the rotating shaft, the end, provided with a hole, of the spring steel extends out for a certain distance in the tangential direction of the rotating shaft and is connected with a supporting rope of the flexible protection system through the hole, and the other end of the spring steel is welded to the rotating shaft.The pin shaft is sleeved with the rotating shaft, a small gap is reserved, the pin shaft is connected with upper and lower clamp flange plates of the C-shaped clamp through bolts, the arc-shaped lugplate is welded to a C-shaped clamp web, and a lug plate reserved hole is connected with another supporting rope of the flexible protection system. When the flexible protection system is impacted, thespring steel connected with the corresponding supporting rope is pulled and rotated around the rotating shaft, the spring steel is changed into a straightened state from a bent state, and energy is dissipated through plastic deformation of the spring steel. After impact, the spring steel can be coiled into a spring shape around the rotating shaft from the straightened state for repeated use. Theenergy dissipator is reasonable in structural design, clear in energy dissipation mechanism, high in energy dissipation capability, convenient to disassemble, assemble and maintain, suitable for narrow space installation and capable of being repeatedly used.

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...
