井下液压支架组装时需利用台棚起吊,原来使用单体柱支撑,支点面积小,整体稳定性不好,操作复杂,不安全可靠。该新型液压台棚使用四根20/45立柱支撑,立柱下方连接支承座,支承座下面接触底板,整体结构稳定,使用液压操纵阀组控制,操作简便,上面四根钢梁连接,强度高,保证起吊支架,该设备在井下使用效果很好。 Downhole hydraulic support assembly required the use of platform lifting, the original use of single column support, fulcrum area is small, the overall stability is not good, complex operation, unsafe and reliable. The new hydraulic platform shed uses four 20/45 pillar supports, the lower part of the pillar is connected with the support seat, the bottom of the support seat is contacted with the bottom board, the overall structure is stable and controlled by the hydraulic control valve group, the operation is simple, the four steel beams are connected with high strength, To ensure the lifting bracket, the device works well downhole.
