Universal vertical shock-resistant rigidity-variable damping self-adaptive vibration-isolation shock-isolation device

Abstract

The invention discloses a universal vertical shock-resistant rigidity-variable damping self-adaptive vibration-isolation shock-isolation device which comprises a large ring steel wire rope loop (6), a large ring upper clamping plate (7), a lower clamping plate (3), a small ring steel wire rope loop (5), a small ring upper clamping plate (4), an upper cover plate (1) and a lower cover plate (2). Steel wires are wound in a certain direction to form multiple strands of stainless steel wire ropes, and then the large ring steel wire rope loop (6) and the small ring steel wire rope loop (5) which are different in diameter are formed by the stainless steel wire ropes. One end of the large ring steel wire rope loop (6) and one end of the small ring steel wire rope loop (5) are fixedly screwed on the upper cover plate (1) through upper clamping plate bolts, and the other end of the large ring steel wire rope loop (6) and the other end of the small ring steel wire rope loop (5) are sequentially fixed onto the lower clamping plate (3) and are screwed on the lower cover plate (2) in a bolt connecting mode. The double-ring-type steel wire rope shock absorber overcomes the defects that a steel wire rope vibration-isolation device in the prior art is high in production cost, prone to fatigue failure, complex to install, fixed in rigidity and the like, the damping of the double-ring-type steel wire rope shock absorber is increased by one time compared with that of a traditional steel wire rope shock absorber, and dynamic loads can be attenuated quickly.

Description

technical field [0001] The invention relates to a general-purpose vertical shock-resistant vibration and shock isolation device, in particular to a general-purpose vertical shock-resistant and variable-stiffness damping self-adaptive vibration and shock isolation device. Background technique [0002] The wire rope vibration isolation device mainly uses the friction between the steel wires and the strands of the wire rope to perform vibration isolation. When the external load is small, the deformation of the wire rope is approximately linear. When the load continues to increase and the displacement of the vibration isolation device increases to a certain extent, slippage occurs between the strands of the steel wire rope. At this time, the stiffness characteristics of the vibration isolation device of the wire rope change, and the stiffness becomes "soft". [0003] The performance of the spiral wire rope vibration isolation device is single. When the wire rope is determined a...

Problems solved by technology

[0005] The purpose of the present invention is to provide a general-purpose damping self-adaptive vibration and shock isolation device with vertical shock resistance and variable stiffness, which solves the problem that the existing steel wire rope shock absorber cannot change the natural frequency of the system once it is set. In case of impact vibration, it cannot effectively isolate shock and vibration
