Problems solved by technology
Although this kind of vibration isolator can reduce the absolute acceleration response amplitude of the equipment, it will produce a relatively large relative displacement. If the relative displacement of the equipment is too large, it may cause damage to the equipment's attached piping and cables, and even exceed the vibration isolation. The ultimate deformation capacity of the device itself

Embodiment Construction
[0024] A scale-type anti-shock isolation device, a first anti-shock passage and a second anti-shock passage connected in series are arranged between the equipment and the equipment carrier, and the cross-sectional area of the first anti-shock passage is smaller than that of the second anti-shock passage Cross-sectional area; the top of the first anti-shock channel is connected to the equipment, and the bottom end of the second anti-shock channel is connected to the equipment carrier; the first anti-shock channel is provided with an energy storage device for storing impact energy or for dissipating impact energy material, the internal space between the first anti-shock channel and the second anti-shock channel is provided with a medium for transmitting impact energy. Since the second anti-shock channel is connected to the equipment carrier, when it is impacted, the equipment carrier transmits the impact energy to the first anti-shock channel through the second anti-shock chann...

The invention discloses a scaling type impact-resistant isolation device. According to the scaling type impact-resistant isolation device, a first impact-resistant channel and a second impact-resistant channel, connected in series, are arranged between a device and a device carrier; the sectional area of the first impact-resistant channel is less than that of the second impact-resistant channel; the top end of the first impact-resistant channel is connected with the device; the bottom end of the second impact-resistant channel is connected with the device carrier; an energy storage device or a material is arranged in the first impact-resistant channel; the energy storage device is used for storing impact energy; the material is used for dissipating the impact energy; and a medium for transmitting the impact energy is arranged in an inner space between the first impact-resistant channel and the second impact-resistant channel. Compared with the prior art, a relative displacement response amplitude between the device and foundation is greatly reduced under the promise that an absolute acceleration amplitude of an isolated device is retained or reduced in an impact response process.
Description
technical field [0001] The invention relates to the field of impact isolation of mechanical equipment, in particular to a scaling type anti-shock isolation device. Background technique [0002] Whether mechanical equipment or facilities can operate safely when subjected to large energy impacts (such as buildings subjected to earthquakes, ship collisions, explosion impacts, drop impacts, etc.) Important engineering application value. The key technology is how to design products that simultaneously reduce the absolute acceleration response amplitude of the isolated equipment and the relative displacement response amplitude between the isolated equipment and the ship foundation. [0003] The traditional shock protection measures are to install a vibration isolator in the shock isolation system, store the strong impact energy in the form of potential energy in the vibration isolator to the maximum extent, and then store the The energy is released slowly to achieve the effect o...
