A kind of above-mentioned preventing from falling into well helicoid hydraulic motor, wherein, the rectangular triangular structure in recess section, and apex angle a is
50°。
A kind of above-mentioned preventing from falling into well helicoid hydraulic motor, wherein, the bulge loop section structure in a rectangular trapezoid.
The beneficial effects of the utility model are：
The utility model structure novel is compact, reasonable design, using easy to assembly, sliding block is formed not using main ring and slip ring
It influences by-passing valve and flows through drilling fluid, by the slip ring on guide rod sliding block with protrusion with coordinating, and with right angle with slideway shape
The runner rails structure of triangular notches when making transmission collar fracture failure, when top is with gravity downlink, passes through right angle
Trapezoidal bulge loop structure blocks protrusion, good mechanical property, while L-shaped sliding sleeve compresses compressed spring, by elastic recovery damping and
When anti-falling stop well accident, low cost occupies little space, and saves raw material, easy to process, anti-lost effect is good, highly practical, is conducive to
The construction time is saved, reduces loss.
