Embodiment 1

[0050] combine Figure 1 to Figure 6 The shock absorbing device of the present invention is described in detail.

[0051] The damping device includes a support device 1, a quality device 2 and a stiffness device 3; the quality device includes a three-stage quality ring; the stiffness device 3 includes three sets of stiffness rods, and the quality ring is fixedly installed on the support through the stiffness rods above device 1. The annulus of the tertiary quality rings are in the same plane, and are laid out in the form of concentric rings. The series numbers of the primary, secondary and tertiary mass rings correspond one-to-one to the stiffness rods of the first, second and third stages. The supporting device 1 comprises a first horizontal support and a second horizontal support; the bottom of the first horizontal support and the second horizontal support are provided with two protrusions; the protrusions on the first horizontal support are vertical to the radial directio...

Abstract

The invention proposes a rod-type tuning mass damper shock absorber, which belongs to the technical field of shock absorbers, and solves the problem of insufficient shock resistance of porcelain column type electrical equipment. The damping device includes a support device, a quality device and a stiffness device; the quality device includes an N-level quality ring, wherein N is a positive integer; the stiffness device includes N groups of grade stiffness rods, and the quality ring is fixed by a stiffness rod Installed above the support device, the ring surfaces of the N-level quality ring are on the same plane, and are arranged in the form of concentric rings. There is a one-to-one correspondence between the stages of the mass rings and the stages of the stiffness rods. The shock absorbing device has extremely low redundant quality, good shock absorbing stability, can adjust its own size according to the required space, has little interference to the controlled equipment, and is not easy to age.

Description

technical field [0001] The invention relates to a rod-type tuning mass damper damping device, belonging to the technical field of damping devices. Background technique [0002] Earthquake disasters are sudden and devastating, which seriously threaten the safety of human life and property. Porcelain column electrical equipment is widely used in power systems, and with the development of the power industry, the level of power transmission and transformation equipment is getting higher and higher, and high-voltage electrical equipment, especially ultra-high voltage DC power transmission and transformation equipment, is becoming more and more detailed The quality of the top is getting bigger and bigger, and the requirements for its anti-seismic performance are higher. Porcelain column electrical equipment has been severely damaged in previous strong earthquakes at home and abroad. It is very important to ensure the normal operation of porcelain column electrical equipment under...
