Embodiment 2

[0032] In addition to the components provided in the first embodiment, the rail-type shock-isolating device of this embodiment is also provided with vertical elastic shock-isolating elements and energy-dissipating elements. Such as Figure 4 As shown, a vertical vibration isolation spring 10, a vertical guide rod 14 and a base plate 11 are arranged under the bottom plate 5;

[0033] Briefly describe the working process of the guide rail type seismic isolation device of the present invention below: when an earthquake occurs in the area where the article to be protected is located, the base plate generates vibrations in the horizontal direction and the vertical direction together with the ground and the floor surface, and the horizontal direction The movement of the upper plate is isolated by the relative sliding of the horizontal guide rail slider mechanism and the longitudinal guide rail slider mechanism, and the vertical movement is isolated by the up and down movement of the...

Abstract

The invention discloses a guide rail type shock isolation device. The guide rail type shock isolation device comprises an upper board, a middle board, a bottom board and guide rails. The guide rails comprise transverse guide rails and longitudinal guide rails, the transverse guide rails and the longitudinal guide rails are orthogonal, and the transverse guide rails are fixed to the bottom board and provided with a transverse sliding block which can slide along the transverse guide rails and has the function of drawing resistance. The middle board is fixed to the upper portion of the transverse sliding block and fixedly provided with the longitudinal guide rails. A longitudinal sliding block which can slide along the longitudinal guide rails and has the function of drawing resistance is arranged on the longitudinal guide rails. The upper board is fixed to the upper portion of the longitudinal sliding block and used for bearing objects. Reset springs are horizontally arranged between the upper board and the middle board and between the middle board and the bottom board respectively. The guide rail type shock isolation device not only has the function of isolating shock in any horizontal direction, but also has the shock absorption and energy absorption effects, and can be used for shock absorption and isolation of precious relics or precision equipment.

Description

technical field [0001] The invention relates to the technical field of shock absorption (vibration) and shock isolation (vibration), in particular to a guide rail type shock isolation device. Background technique [0002] Cultural relics with important cultural, historical and artistic value, or some compact equipment have high requirements for shock resistance during preservation or storage. However, in general, such objects are mainly in the form of floating, which is very vulnerable to earthquakes. destroy. [0003] In the Wenchuan earthquake, at least 68 national key cultural relics protection units and 142 provincial-level document protection units in Sichuan Province suffered losses. The World Cultural Heritage Erwang Temple Complex in Dujiangyan and the cultural relics of Yunyan Temple, a national key cultural relic protection unit, collapsed in large areas, and all those that did not collapse became dilapidated buildings; 1,645 cultural relics were lost, including 1...
