澳大利亚Hydramatic工程有限公司研制了一种可快速安装长壁工作面顶板锚杆的锚杆安装机.该锚杆机利用几个卡爪骑在工作面输送机溜槽上,并由一个可快速移动的滑块固定.锚杆机的牵动链轮安装在滚筒采煤机尾部.锚杆由支撑式支架的液压系统提供动力.试用表明,锚杆机每天可支护工作面顶板105m,并且锚杆机对以倾斜和旋转作业.
Hydramatic Engineering Co. Ltd. of Australia has developed a bolt mounter that can quickly install longwall face roof bolts that use several jaws to ride on the face conveyor chute and consist of a quick-moving The slider is fixed.The bolt sprocket of the anchor machine is installed on the tail of the drum shearer.The bolt is powered by the hydraulic system of the support bracket.The trial shows that the bolt machine can support the roof of the working face 105m every day and the bolt machine To tilt and rotate the job.
