古田二级电站装有两台水轮发电机组,共有4孔平板尾水闸门,门体尺寸为4,360毫米×5,325毫米,门重8吨。过去用一台2×5.5吨启闭机装在移动台车上作为启闭设备,每次起落门都要倒换钢丝绳,劳动强度大,耗费时间长。为了改变这种情况,我厂在利用原有启闭机的基础上自行设计了一种螺旋式自动抓梁,这种抓梁不需要用人力改换挂脱钩装置的位置,而是在完成挂钩后即为脱钩做好准备,完成脱钩后即为挂钩作好准备,比其他一些自动抓梁又提高了一步。现将这种螺旋式自动抓梁介绍如下。
Gutian II hydropower station equipped with two hydro-generating units, a total of 4-hole flat tail gate, the door size of 4,360 mm × 5,325 mm, the door weighs 8 tons. In the past with a 2 × 5.5 t hoist mounted on the mobile trolley as a hoist equipment, each landing gear to be switched rope, labor-intensive, long time-consuming. In order to change this kind of situation, our factory designed a kind of spiral automatic grasping beam on the basis of using the original hoist. This kind of grasping beam does not need to manually change the position of the hook-removing device, but after the completion of the hooking That is, ready for decoupling, that is, the hook is ready after the decoupling is completed, and the grasping step is further enhanced than some others. Now this spiral automatic grasping beam as follows.
