Abstract

The invention provides a bidirectional roller type shock insulation device and a design method. The bidirectional roller type shock insulation device sequentially comprises a bottom plate, a rail support set, a curvature rail set, a roller set and a top plate from bottom to top. The curvature rail set comprises fixed curvature rails and floating curvature rails. A rectangular structure is formed by the fixed curvature rails and the floating curvature rails along the four edges of the bottom plate sequentially and alternately in an enclosed mode. The roller set comprises fixed rail rollers and floating rail rollers. The bidirectional roller type shock insulation device is simple in structure, the purpose of shock insulation is achieved through rolling of the rollers on the curvature rails, and different shock insulation effects are achieved by adjusting the curvature radius of the rails; the rails are arranged in the same layer, so that the height of the shock insulation device is decreased; and the occupied space of the device is reduced.

Description

technical field [0001] The invention relates to the technical field of shock absorption and isolation, in particular to a design method for a two-way roller type shock isolation device used in the technical field of shockproof protection of cultural relics. Background technique [0002] Museums are the carriers that make cultural relics come alive in the protection and utilization of cultural relics. A large number of movable cultural relics flow to museums for centralized storage, which also increases the possibility of massive damage under sudden disasters such as earthquakes. More than 60% of museums in my country are located in a strong earthquake-prone earthquake zone. The 5.12 Wenchuan earthquake in 2008 caused damage to no less than 2,766 cultural relics in the collection. Anti-seismic measures for cultural relics in museums can be divided into two types: anti-seismic and anti-seismic methods. As far as the current situation of floating cultural relics in our country’...
