High-pressure grease shock insulation support

Abstract

The invention belongs to the technical field of shock insulation, and relates to a high-pressure grease shock insulation support. The high-pressure grease shock insulation support comprises an upper cover plate and a lower cover plate, wherein a sleeve is arranged between the upper cover plate and the lower cover plate, and a steel ring is arranged on the periphery of the sleeve; a pressure-bearing block is arranged in the sleeve, an upper polytetrafluoroethylene ring is arranged between the pressure-bearing block and the upper cover plate, a lower polytetrafluoroethylene ring is arranged between the pressure-bearing block and the lower cover plate, a space defined by the upper polytetrafluoroethylene ring, the upper cover plate and the pressure-bearing block is filled with grease, and a space defined by the lower polytetrafluoroethylene ring, the lower cover plate and the pressure-bearing block is filled with grease; and the sleeve comprises an upper sleeve and a lower sleeve, an upper closing-up ring plate is additionally arranged at the top end of the inner diameter of the upper sleeve, the upper closing-up ring plate is obliquely arranged from outside to inside from bottom to top, the upper closing-up ring plate is pressed between the wall of the upper polytetrafluoroethylene ring and the upper cover plate, and the bottom of the lower sleeve is in contact with the lower cover plate. According to the high-pressure grease shock insulation support, a shaking and collision mechanism can be omitted, the bearing capacity is higher, the anti-seismic effect is better, the structure is simple, the size is small, the weight is light, the cost is low, and transportation and installation are convenient.

Description

technical field [0001] The invention relates to a high-pressure grease shock-isolation bearing, which belongs to the field of shock-isolation technology. Background technique [0002] Disasters caused by strong earthquakes are mainly caused by horizontal seismic waves (horizontal vibrations), that is, horizontal acceleration. Therefore, it is stipulated that when the horizontal acceleration reaches 0.1g, its seismic intensity (destruction) is 7°. To eliminate earthquake disasters, it is necessary to Try to reduce the seismic horizontal acceleration. The current shock isolation device has a large friction material area and a large friction coefficient. In order to overcome the problem that the static friction coefficient will become larger, a shaking mechanism is required. Therefore, the existing shock isolation device has a complex structure, large volume, heavy weight, and high cost. .
