The lower end become is connected with drilling rod radially regulator joint and drill bit radially regulator joint by telescoping tube respectively.Wherein, horse
The structure reaching assembly specifically includes that stator, the rotor being arranged in stator, arranges rubber blanket between the stator and the rotor.Former
Carrying out rubber blanket to be set directly between stator and rotor, during using, rubber blanket easily comes off, and causes rotor to damage
Bad, service life is short, easily causes down-hole accident.
Summary of the invention
The technical problem to be solved is: provide the stator rubber anticreep helicoid hydraulic motor of a kind of good anti-drop effect.
In order to solve above-mentioned technical problem, the technical solution used in the present invention is: stator rubber anticreep spiral shell
Bar drill has, including: motor assembly that by-pass valve assembly is connected with by-pass valve assembly lower end and motor assembly lower end phase
The universal drive shaft assembly connected and the driving-shaft assembly being connected with universal drive shaft assembly lower end, the upper end of described by-pass valve assembly and institute
The lower end stating driving-shaft assembly is connected with drilling rod radially regulator joint and drill bit radially regulator joint by telescoping tube respectively
Connecing, the structure of described motor assembly includes: stator, the rotor being arranged in stator, arranges rubber between the stator and the rotor
Pad, is evenly arranged with some T-shaped grooves, is provided with and T-shaped groove phase interworking on described rubber blanket in the inner side of described stator
Close T-shaped rubber bumps, in the stator of described T-shaped groove both sides, be provided with counter sink, be provided with in described counter sink with
The sunk screw that rubber blanket cooperates.
The invention have the advantage that said stator rubber anticreep helicoid hydraulic motor, novel structure, rubber blanket uses T-shaped protruding edge
It is embedded in stator, and by sunk screw, T-shaped projection is fixed, Stability Analysis of Structures, good anti-drop effect, it is possible to prevent rubber blanket
Come off during using, it is ensured that the safety of underground work, service life is long.
