一种水电站竖斜井压力钢管安装辅助设备及其安装方法,包括用于安装到压力钢管管节外壁的多个提升环,以及用于安装到工作井内的多个轨道,提升环上环形均布的安装有多个驱动装置,轨道纵向的安装在工作井内壁,轨道的数量与提升环上安装的驱动装置数量对应,提升环上驱动装置的提升齿轮分别与对应轨道的齿条啮合传动。通过上述结构,实现压力钢管的平稳下降安装,有效保证压力钢管管节中心轴线始终沿竖井或斜井中心线运动就位,若出现不对正的情况,通过各轨道上伸缩装置的协调运行,推动压力钢管调整中心轴线位置,从而实现压力钢管的对正,不需要人工参与纠偏,根本上保证了施工安全和效率。
The hydropower station vertical inclined shaft pressure steel pipe installation auxiliary equipment comprises a plurality of lifting rings used for being installed on the outer wall of a pressure steel pipe joint and a plurality of rails used for being installed in a working well, a plurality of driving devices are annularly and evenly installed on the lifting rings, and the rails are longitudinally installed on the inner wall of the working well. The number of the rails corresponds to that of the driving devices installed on the lifting ring, and lifting gears of the driving devices on the lifting ring are in meshing transmission with the racks of the corresponding rails respectively. By means of the structure, stable descending installation of the pressure steel pipe is achieved, it is effectively guaranteed that the central axis of a pipe joint of the pressure steel pipe always moves in place along the central line of a vertical shaft or an inclined shaft, if misalignment occurs, the pressure steel pipe is pushed to adjust the position of the central axis through coordinated operation of the telescopic devices on the rails, and therefore alignment of the pressure steel pipe is achieved. And manual deviation correction is not needed, so that the construction safety and efficiency are fundamentally ensured.
