Abstract

The invention discloses a multi-frequency hydraulic rotating impact drill and relates to the field of impact drill manufacturing, in particular to the multi-frequency hydraulic rotating impact drill comprising an impact mechanism, a rotating mechanism and a reverse striking mechanism which are connected sequentially. A reversing mechanism and a reversing valve are mounted on the outer side of the impact mechanism. At least two first motors are mounted on the rotating mechanism, and at least one second motor can be additionally mounted on the rotating mechanism. The structure is simple, split type connecting is achieved, transportation is facilitated, and the limit of the regional environment to the impact drill is reduced.

Description

technical field [0001] The invention relates to the field of impact drill manufacturing, in particular to a multi-frequency hydraulic rotary impact drill. Background technique [0002] The construction of bridges, ports, water conservancy and high-rise buildings is characterized by complex strata, enlarged apertures, and deepened depths. For sand layers, pebble layers, boulder layers, and bedrock, impact drilling is one of the most effective drilling methods. First, the mechanical operation efficiency is high and the benefit is good. The hydraulic cylinder impact has the advantages of stable operation, low noise, convenient operation, labor saving, stepless adjustment of stroke and stroke times, overload protection and automatic control, etc., and it has been used in a wider range. However, due to the large volume and complex structure of the hydraulic impact drill, it brings great inconvenience to the transportation and use of the impact drill, which limits the scope of us...
