The invention relates to a steel structure roof lifting and sliding system which is characterized in that the tops of a plurality of supporting frames are fixedly connected with the same channel steel, the tops of two sliding plates on one side of the channel steel are fixedly connected with a plurality of first connecting frames, and the inner walls of the first connecting frames are rotationally connected with the outer walls of first rotating shafts in a penetrating mode and fixedly sleeved with take-up rollers; a steel wire rope is fixed and wound on the outer wall of the take-up roller, and the other end of the steel wire rope is connected with the roof; the top of the channel steel is fixedly connected with a hydraulic cylinder, and the output end of the hydraulic cylinder is fixedly connected with one end of the sliding plate and used for driving the sliding plate to transversely move. The transmission structure is arranged on one side of the first connecting frame and used for driving the first rotating shafts to rotate at the same time, so that lifting is stable. The anti-falling mechanism is arranged at the top of the first connecting frame and used for preventing the roof from falling when the steel wire rope breaks. The stabilizing mechanism is arranged below the sliding plate and is used for stabilizing the sliding plate when the sliding plate moves; the synchronous lifting and sliding process of the whole steel structure roof is more stable and safer.

本发明涉及一种钢结构屋盖提升滑移系统，多个支撑架的顶部固定连接有同一个槽钢，槽钢的一侧两个滑动板的顶部固定连接有多个第一连接架，第一连接架内壁贯穿转动连接第一转动轴的外壁固定套设有收线辊，收线辊的外壁固定并绕设有钢丝绳，钢丝绳的另一端与屋盖连接；槽钢的顶部固定连接有液压缸，液压缸的输出端与滑动板的一端固定连接，用于带动滑动板横向移动；传动结构设置在第一连接架的一侧用于同时带动多个第一转动轴转动，使其升降稳定；防坠落机构设置在第一连接架的顶部用于防止钢丝绳断裂时屋盖发生坠落；稳定机构设置在滑动板的下方，用于对滑动板移动时更加稳定；整个钢结构屋盖同步提升滑移过程更加平稳安全。
