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

The invention relates to an anti-pull and shock-isolation support capable of realizing hierarchical multi-stage control effects, and belongs to the technical field of shock-proof and shock-isolation equipment. It solves the problem that the ceramic column type electrical equipment is damaged during the earthquake, which seriously affects the operation of the power system, and the problem that the existing seismic isolation device cannot realize hierarchical multi-stage control. Technical points: The end of the sliding rail of the present invention is fixed on the ground, and each sliding rail is slidably installed with the lower parts of the two connecting sliding sleeves. The first and third-stage springs are set on the end of the sliding rail. In the middle of the lower rail; the upper rail and a pair of lower rails are arranged perpendicular to each other, the upper rail is fixedly connected with the platform, the upper part of the connecting sliding sleeve is set on the upper rail, and the second and third stage springs are set on the end of the upper rail. The second and second stage springs are set in the middle of the upper slide rail, and the lead rubber bearing is fixedly installed between the ground and the platform. The invention is especially suitable for protecting thin and tall equipment from damage during earthquakes.
Description
technical field [0001] The invention relates to a shock-isolation support, in particular to a pull-out shock-isolation support capable of realizing hierarchical multi-stage control effects, and belongs to the technical field of shock-proof and shock-isolation equipment. 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 towering and Soft and soft, the quality is getting bigger and bigger, and the requirements for its shock resistance are higher. Porcelain column electrical equipment has been severely damaged in previous strong earthq...
