Large-tonnage vertical shock insulation damping device

Abstract

The invention relates to a large-tonnage vertical shock insulation and absorption device, which is the vertical shock insulation and absorption device for resisting vibration (shocking) vertically for civil engineering structures and mechanical engineering. The device comprises lead extrusion dampers (1), a steel plate spring (2), an upper steel plate (3), and a lower steel plate (4). On the overall structure, the steel plate spring (2) is arranged in the centre, while a plurality of lead extrusion dampers (1) are arranged on the periphery symmetrically; the upper part of each damper (1) is connected to the upper steel plate (3) respectively while the lower part of each damper (1) is connected with the lower steel plate (4) respectively, so that all the dampers (2) are connected into a whole; and the upper part of the steel plate spring (2) in the centre is connected with the upper steel plate (3) through a ball bearing (5) while the lower part thereof is connected with a steel block (9) through a bolt (6), and the steel block (9) is connected with the lower steel plate (4). The invention combines the advantages of the lead extrusion dampers (1) and the steel plate spring (2) to form the large-tonnage vertical shock insulation and absorption device. The large-tonnage vertical shock insulation and absorption device has the advantages of good vertical shock insulation and absorption capacity, low price and convenient manufacturing.

Description

technical field [0001] The invention is a vertical vibration isolation and shock absorption device for civil engineering and mechanical engineering structures, especially for large tonnage vertical load-bearing structures. Background technique [0002] Earthquake vertical action often needs to be considered in design. Many earthquake damage phenomena show that in high-intensity earthquake areas, the impact of the vertical acceleration component of earthquake motion on the damage state and degree of building is obvious. According to a large number of strong earthquake records that have been obtained at home and abroad, during an earthquake, the peak value of the vertical acceleration is likely to reach or even exceed the peak value of the horizontal acceleration. Therefore, the "Seismic Code" stipulates that for large-span structures, long cantilever structures, chimneys and similar high-rise structures at Intensity 8 and 9, and high-rise buildings at Intensity 9, vertical se...

Problems solved by technology

Ordinary shock absorbers can dissipate energy vertically, but lack sufficient vertical bearing capacity

Ordinary shock isolation devices are rubber bearings, which are cheap to manufacture, but lack energy dissipation capacity, and rubber bearings cannot be used in high-temperature environments. Rubber bearings are prone to aging and lose their effectiveness in special environments.
