The invention discloses a coal mine monorail crane longitudinal beam installing and lifting device which is composed of a fixed support, a hydraulic telescopic beam and a movable platform, the movable platform and the telescopic beam are matched and horizontally installed at the top end of the telescopic beam and used for bearing a monorail crane longitudinal beam, the telescopic beam is an n-shaped frame, and the fixed support is arranged at the lower end of the telescopic beam. Walking wheels are installed at the bottom of the fixed support, a fourth pulley, a fifth pulley, a second pulley and a third pulley are arranged on the movable platform and the rear portion of the telescopic beam from top to bottom respectively, a winch is arranged on the fixed support, and a steel wire rope on the winch sequentially winds around the second pulley, the third pulley, the fourth pulley and the fifth pulley and is fixed to the telescopic beam. Limiters are further arranged on the lower portion of the telescopic beam, when the movable platform ascends to the top end of the telescopic beam, the limiters are triggered, the telescopic beam starts to stretch out, and a winch switch is switched off when the telescopic beam reaches the designated height.
本发明公开了一种煤矿单轨吊纵梁安装托举装置,由固定支架、液压伸缩梁、移动平台三部分组成,其中移动平台与伸缩梁配合水平安装在伸缩梁顶端,用于承载单轨吊纵梁,伸缩梁为门字形框架,伸缩梁下端设置着固定支架,固定支架底部安装着行走轮,移动平台以及伸缩梁后部由上到下分别设置着四号滑轮、五号滑轮、二号滑轮、三号滑轮,固定支架上设置着卷扬机,卷扬机上的钢丝绳依次绕过的滑轮为二号滑轮、三号滑轮、四号滑轮、5号滑轮,固定在伸缩梁上;通过卷扬机绕钢丝绳实现移动平台的升降,伸缩梁下部还设置着限位器,当移动平台升至伸缩梁顶端时限位器触发,伸缩梁开始伸出,到达指定高度时断开卷扬机开关。
