| Abstract:In view of the fact that the pile holes of signal tower foundation in domestic mountainous areas are broken manually by water grinding drill combined with air pick, which takes a long time and has a high risk factor, Therefore, the market is in urgent need of a kind of equipment which can reduce the labor intensity, has high safety factor, has fast breaking speed, and is suitable for manual handling and disassembly. At present, the commonly used flat foundation pile drilling equipment mainly includes: shaft drilling machine, raise boring machine and shaft boring machine, etc. these equipment have large weight and external dimension, difficult handling and poor adaptability to complex terrain and mountainous conditions. According to the above situation, a YXW-2000 hydraulic milling machine,was developed. It can effectively improve the mechanization degree of pile hole construction in mountainous area, reduce the labor intensity of workers, and improve the safety of equipment operation. This paper mainly introduces the main technical parameters, structural layout characteristics and hydraulic system of hydraulic rotary excavator. The test results show that YXW-2000 hydraulic milling machine can meet the mechanization requirements of drilling construction, has good disintegration and convenient handling, and has a good application prospect. |
