Description

一种矿井用抗冲击地压的自动支护装置 技术领域
本发明涉及矿井支护技术领域，具体地说是涉及一种矿井用抗冲击地压的自动支护装置。
 背景技术
矿井支护是指在采掘过程中，为保证矿井的稳定和安全，采取一系列的措施来支撑矿井壁、顶板和底板的工程技术。随着矿井开采深度的不断增加，巷道冲击地压的发生频率和破坏强度也逐渐增加。冲击地压是煤矿开采中遇到的严重动力灾害，当冲击地压发生时，井下巷道远场围岩释放能量，造成支护装置的瞬间破坏。现有的支护装置对矿井侧壁无法进行支护，无法保证实现对矿井巷道的完全支撑，同时在应对冲击地压时难以达到对冲击地压的缓冲，且当冲击力较大时，支护装置中的液压支柱会发生形变，造成支护装置的损坏，进而无法保证对矿井巷道的支撑。
 技术解决方案
为了克服上述背景技术中所阐述的缺点，本发明提供了一种矿井用抗冲击地压的自动支护装置。本发明所采用的技术解决方案如下：一种矿井用抗冲击地压的自动支护装置，包括有对称分布的底座，底座滑动连接有滑动架，底座固接有液压杆，液压杆的伸缩端与相邻的滑动架固接，滑动架固接有支架，对称分布的支架设置有主支撑板，主支撑板设置有等间距且对称分布的第一推杆和等间距且对称分布的第三推杆，主支撑板固接有对称分布的第二推杆和对称分布的第四推杆，第二推杆和第四推杆分别滑动连接有活塞板。
有益效果：本发明通过压缩活塞板与第四推杆之间的弹簧，减缓了矿井发生冲击地压时本装置受到的冲击力，同时对矿井起到支撑作用，保证了矿井顶部的稳定；通过移动第一推杆和第三推杆的位置，增大顶板对矿井坍塌部位的支撑力，进而减缓矿井发生冲击地压时本装置受到的冲击力，避免本装置在应对矿井的冲击地压时发生损坏；通过侧支护板增大对矿井顶部的支撑面积，同时通过第五推杆对矿井坍塌所引起的冲击力进行缓冲，确保了矿井侧壁的稳定；通过第一弹块对滑动座进行限位以及棘条对棘爪的限位，防止由于矿井的坍塌而导致侧支撑板和滑动架的移动，保证了对矿井的支撑作用，同时通过滑动架和侧支撑板对矿井的两侧进行支撑，提高了矿井的稳定性；通过第三弹块对下支杆的限位，避免在矿井发生坍塌时，掉落的石块对本装置进行挤压而压坏本装置，进而使本装置失去对矿井的支撑作用，同时对称分布的上支杆和下支杆将掉落石块的挤压力分散至两侧，提高了本装置的稳定性；通过第二弹块对接触架的限位，使接触架向下移动后无法复位，避免由于矿井底部的塌陷而导致本装置失去对矿井的支撑作用，进一步减缓了矿井由于塌陷时本装置受到的冲击力。
