冲抓式打井机是一种动力打井机,它利用单索控制冲抓锥头来进行打井造孔施工。 主要工作部件是冲抓锥头,它用在井孔中上下作业,开挖和抓住砂石泥土。借助于自动开闭装置和自动挂卸器以及接绳器的动作配合,实现了单索控制冲抓锥头工作。 冲抓锥头打井造孔作业共有五个工步,现将每个工步工作原理叙述如下: (一) 脱钩下锥:扳动卷扬机手柄,使锥头略上升少许,立即刹车,脱开离合器。然后慢慢放松刹车,使锥头慢慢下降。三个挂钩已跳出锥头,即可脱钩,使锥头慢而稳地落入井孔。
The rush-drilling rig is a power-drilling rig. It uses a single-cable to control the boring head to drill holes. The main working part is the punching cone head, which is used to work up and down in the wellbore to excavate and grab the gravel soil. With the help of the automatic opening and closing device and the action of the automatic unloader and the rope catcher, the single-cable control punching and taper head work is realized. There are a total of five steps for the drilling and drilling of the cone head. The working principle of each step is now described as follows: (1) Unhook the lower cone: Pull the handle of the hoist so that the cone slightly rises slightly and brake immediately. clutch. Then slowly relax the brake and slowly lower the cone head. The three hooks have jumped out of the cone head and can be unhooked so that the cone head falls slowly and steadily into the well bore.
