Earthquake self-rescue device with adjustable damping stiffness of hydro-pneumatic spring and working method

Abstract

The invention discloses an earthquake self-rescue device with adjustable damping stiffness of a hydro-pneumatic spring and a working method. The earthquake self-rescue device comprises a protective cabin device, oil-gas buffer damping devices, a protective bed device and a protective bed braking device; the protective cabin device is placed on a bedroom ground foundation, and the oil-gas buffer damping devices are hinged to mounting seats on the inner wall of the protective cabin device through bolts; a bed body of the protective bed device is hinged to mounting holes of the oil-gas buffer damping devices through the mounting seats, and the side end of the protective bed device is fixedly arranged on the inner wall of the protective cabin device through a bearing seat; and the protective bed braking device is arranged inside the bed body of the protective bed device through a slewing bearing, and the side end of the protective bed braking device is fixedly arranged on the inner wall ofthe protective cabin device through a bearing seat and a mounting support. According to the earthquake self-rescue device with adjustable damping stiffness of the hydro-pneumatic spring and the working method, personal safety of personnel is achieved through multiple protection of the protective cabin device, the protective bed device and the protective bed braking device, and the personnel are prevented from being impacted and injured through secondary buffering of the oil-gas buffer damping devices.

Description

technical field [0001] The invention relates to the technical field of lifesaving tools, in particular to an earthquake self-rescue device with adjustable damping stiffness of an oil-gas spring and a working method. Background technique [0002] Earthquake is an unavoidable natural phenomenon. my country is a country with high frequency, high intensity, shallow epicenter and wide distribution. In recent years, earthquakes have occurred in many places in my country. Huge losses are caused. Human beings cannot prevent the occurrence of earthquakes, especially those living in high-rise buildings. When an earthquake occurs in the middle of the night, people are basically falling asleep. People wake up in a state of ignorance and cannot evacuate immediately, resulting in shorter escape time Casualties are easy, and the time and space for people to avoid shocks is small, and it is easy to suffocate for a long time. Because the earthquake lifesaving equipment that appears on the curr...

[0002] Earthquake is an unavoidable natural phenomenon. my country is a country with high frequency, high intensity, shallow epicenter and wide distribution. In recent years, earthquakes have occurred in many places in my country. Huge losses are caused. Human beings cannot prevent the occurrence of earthquakes, especially those living in high-rise buildings. When an earthquake occurs in the middle of the night, people are basically falling asleep. People wake up in a state of ignorance and cannot evacuate immediately, resulting in shorter escape time Casualties are easy, and the time and space for people to avoid shocks is small, and it is easy to suffocate for a long time. Because the earthquake lifesaving equipment that appears on the current market cannot accurately predict and has poor performance in resisting high-altitude landing impact and anti-heavy object landing impact, the design of a An earthquake self-rescue device with adjustable damping stiffness of an oil-gas spring and its working method are particularly important. The self-rescue bed device adopts a spherical shape so it has very good impact resistance, and a buffer damping device is installed inside, so it has very good anti-drop impact buffer damping capacity
