一种花形薄壁吸能防冲支护装置
摘要：
一种花形薄壁吸能防冲支护装置，属于煤矿安全支护技术领域。本发明包括顶盖、支撑筒及底座，在所述顶盖的下端面中心处设置有第一凸台，第一凸台设置为柱型结构，第一凸台的横截面设置为花形结构；所述支撑筒设置为直筒型结构，支撑筒的横截面设置为花形结构；在所述底座的上端面中心处设置有第二凸台，第二凸台设置为锥型体结构，其锥型体结构顶端横截面设置为花形结构，锥型体结构底端横截面设置为圆形结构，锥型体结构顶端与锥型体结构底端之间采用圆滑渐变过渡；所述顶盖通过第一凸台与支撑筒的上端相连接，支撑筒的下端通过第二凸台与底座相连接；所述顶盖的第一凸台、支撑筒及底座的第二凸台锥型体结构顶端的花形结构相同。
摘要（英）：

The invention discloses a flower-shape thin-wall energy-absorption erosion-prevention shoring device, and belongs to the technical field of safe shoring of a coal mine. The flower-shape thin-wall energy-absorption erosion-prevention shoring device comprises a top cover, a supporting barrel and a base, wherein a first boss is arranged in the center of the lower end surface of the top cover, the first boss is of a columnar structure, the cross section of the first boss is of a flower-shaped structure, the supporting barrel is of a straight barrel-shaped structure, and the cross section of the supporting barrel is of a flower-shaped structure. A second boss is arranged in the center of the upper end surface of the base and is of a cone structure, the cross section of the top end of the cone structure is of a flower-shaped structure, the cross section of the bottom end of the cone structure is of a round structure, and the top end of the cone structure and the bottom end of the cone structure adopt smooth gradual transition, the top cover is connected with the upper end of the supporting barrel through the first boss, the lower end of the supporting barrel is connected with the base through the second boss, and the flower-shaped structure of the first boss of the top cover, the flower-shaped structure of the supporting barrel and the flower-shaped structure of the top end of the cone structure of the second boss of the base are the same.
