Anti-pull vibration isolation support capable of achieving grading multi-step control effect

Abstract

The invention relates to an anti-pull vibration isolation support capable of achieving a grading multi-step control effect and belongs to the technical field of vibration resistance and isolation forequipment. The problems are solved that in the earthquake, knob-insulator-type electrical equipment is damaged, the operation of an electrical system is severely influenced, and an existing vibrationisolation device cannot achieve grading multi-step control. The anti-pull vibration isolation support is characterized in that the ends of lower slide rails are fixed to the ground, the lower portionsof two connection slide sleeves are slidingly installed on each lower slide rail, first third-level springs sleeve the ends of the lower side rails, and first second-level springs sleeve the middlesof the lower slide rails. Upper slide rails are perpendicular to a pair of lower slide rails and are fixedly connected with a platform, the upper portions of the connection slide sleeves sleeve the upper slide rails, second three-level springs sleeve the ends of the upper slide rails, second second-level springs sleeve the middles of the upper slide rails, and a lead core rubber supporting base isfixedly installed between the ground and the platform. The anti-pull vibration isolation support is particularly suitable for protecting thin and tall equipment from being damaged in the earthquake.

Description

Technical field [0001] The invention relates to a seismic isolation support, in particular to a pull-out seismic isolation support that can achieve hierarchical multi-section control effects, and belongs to the technical field of equipment seismic isolation. Background technique [0002] Earthquake disasters are sudden and devastating, and seriously threaten the safety of human life and property. Porcelain-pillar electrical equipment is widely used in power systems. With the development of the power industry, the level of power transmission and transformation equipment is getting higher and higher. High-voltage electrical equipment, especially ultra-high voltage DC power transmission and transformation equipment, is becoming more and more towering and It is delicate and soft, and the quality is getting bigger and bigger, and the requirements for its seismic performance are higher. In the previous strong earthquakes at home and abroad, the earthquake damage of the porcelain colum...

AI Technical Summary

Problems solved by technology

First, the insulation function requirements of the equipment, which makes many shock absorption methods widely used in the field of civil engineering cannot be used for porcelain column electrical equipment

Second, there are wires involved between the equipment, which makes the traditional vibration isolation technology often inconvenient to use, because the vibration isolation may in some cases lead to an increase in the relative displacement between adjacent equipment, making the wires tense and causing equipment damage
