Backfilling device for civil air defense engineering construction

SHI KE

The invention discloses a backfilling device for civil air defense engineering construction. The backfilling device for civil air defense engineering construction comprises a left machine frame, the upper side end surface of the left machine frame is fixedly connected with a fixed block, and the end, away from the left machine frame, of the fixed block is movably connected with a first linkage frame through a rotating shaft; and the side surface of a right machine frame and the side opposite to the left machine frame are movably connected with a lifting frame, the end surface of the lifting frame and one end close to the first linkage frame are connected to the other of the first linkage frame through the rotating shaft. According to the backfilling device for civil air defense engineeringconstruction, the first linkage frame and the second linkage frame controlled by a linkage shaft are arranged on the left machine frame and the right machine frame, matched with a movable wheel installed on a steering shaft, flexible spacing adjustment is achieved, the application range of the distance between backfill pit foundations and special terrain is improved, a water pipe controlled by arolling wheel is arranged on the side surface of the linkage frame, and the efficient pumping and backfilling work for different foundation pit depths can be effectively realized.

本发明公开了一种人防工程建筑用回填装置,包括左机架，所述左机架的上端侧面固定连接有固定块，所述固定块的一端且远离左机架的一端通过转轴活动连接有第一联动架，所述右机架的侧面且相对于左机架的一侧活动连接有升降架，所述升降架的端面且靠近第一联动架的一端通过转轴与第一联动架的另一端活动连接。本发明通过在左机架和右机架设置由联动轴控制的第一联动架和第二联动架，配合安装于转向轴的移动轮，实现灵活间距调节，提高了对回填坑基间距和特殊地形的适用范围，通过在联动架的侧面设置由收卷轮控制伸缩的水管，有效的针对其不同基坑深度实现高效的抽水和回填工作。
