电梯井道防护装置
摘要：
电梯井道防护装置，涉及建筑工程领域的电梯井防坠落消能装置，包括矩形龙骨框架，在矩形龙骨框架内连接弹簧网片，在弹簧网片的下方设置两根工字钢，在每根工字钢与弹簧网片之间均设置弧形弹簧钢片和螺旋形减震弹簧，弧形弹簧钢片的开口端朝上，弧形弹簧钢片的两端分别通过固定支座与龙骨框架连接，每个固定支座分别焊接在龙骨框架上；所述螺旋形减震弹簧设置在弧形弹簧钢片的下方，螺旋形减震弹簧的上端通过弹簧卡片与弧形弹簧钢片的中部连接，螺旋形减震弹簧的下端通过弹簧基座支撑在工字钢上，弹簧基座焊接在工字钢上。本实用新型既能作为隔层防护也能作为底层防护，且在人员坠落后能通过消能设计极大减少受伤程度的电梯井道防护装置。
摘要（英）：

The utility model discloses an elevator shaft protection device, and relates to an elevator shaft fall protection energy dissipator in the field of architectural engineering. The device comprises a rectangular keel frame, wherein a spring mesh is connected in the rectangular keel frame; two pieces of I steel are arranged below the spring mesh; arc-shaped spring steel sheets and spiral damping springs are arranged between each piece of I steel and the spring mesh; the open end of each arc-shaped spring steel sheet faces upwards; the two ends of each arc-shaped spring steel sheet are connected with the keel frame through a fixed support seat respectively; each fixed support seat is welded to the keel frame respectively; the spiral damping springs are arranged below the arc-shaped spring steel sheets; the upper ends of the spiral damping springs are connected with the middle parts of the arc-shaped spring steel sheets through spring clamping sheets, and the lower ends of the spiral damping springs are supported against the I steel through spring bases; the spring bases are welded to the I steel. The elevator shaft protection device can be used as both interlayer protection and bottom layer protection, and the level of injury can be greatly reduced through energy dissipation design after a person falls down.
