Abstract

The invention provides a top hammer type impact rotary power head of a hydraulic drilling machine. The top hammer type impact rotary power head comprises an impact mechanism and a rotary mechanism. The impact mechanism comprises a striking set, a frequency set and a limiting set. The rotary mechanism comprises a rotary set, a reverse striking set, a spline shaft and a reverse striking buffer. The limiting set is connected with the striking set and the frequency set through oil ways. The limiting set controls a piston of the striking set to move, and the frequency set is connected with the striking set and controls the striking frequency of the piston of the striking set. The top hammer type impact rotary power head has the advantages of being simple in structure, high in impacting frequency, large in impact power, wide in application range, long in service life and the like. The top hammer type impact rotary power head can be applied to the hydraulic anchor rod drilling machine, and the impact rotary drilling method is one of the best choices for rock anchoring engineering in which a great number of broken rocks and layers of sand and gravel exist.

Description

technical field [0001] The invention relates to a top hammer impact rotary power head of a hydraulic drilling machine. Background technique [0002] Hydraulic rock bolt rigs are mainly used in power station, highway and railway and other mountain slope treatment anchor cable reinforcement, tunnel pipe shed advance support, foundation pit cable-stayed pile anchor cable, anti-floating anchor rod, ground source heat pump well, roadbed reinforcement, hydropower Engineering dam foundation and dam body anti-seepage treatment, drainage holes, blast holes in mines and quarries, micro pile holes and other projects. The power head of the traditional hydraulic rock bolter is a rotary hydraulic power head, which does not have the impact function. When encountering rock formations or sand and pebble layers, it is necessary to use a down-the-hole impactor to carry out rock breaking operations. It is necessary to match the air compressor and the impactor. The construction cost is high and...
