| Abstract: |
| According to the needs of underground mines and underground engineering for installing friction bolts in China,a new type hydraulic ins-tallation machine for friction bolts is introduced in this paper.The machine is of a new structure and a special automatic feed function without any sup-porting- feed equipment while installing friction bolt. The working principle is discussed. The main points of design of the percussion mechanisim and lock equipment are introduced. The machine is powered with hydraulic energy. It has the advantages of smaller size, less weight, and lower energy consump-tion,etc. |
