Abstract
The utility model relates to oil drilling helicoid hydraulic motor technical field, especially relates to a kind of Novel anti-dropping device helicoid hydraulic motor.Be characterized in comprising the by-pass valve assembly, motor assembly, universal drive shaft assembly and the driving-shaft assembly that are connected successively, falling-proof apparatus is provided with between by-pass valve assembly and motor assembly, described falling-proof apparatus comprises anti-lost connecting rod, anti-lost connecting rod periphery is provided with anti-board falling and anti-lost spacer, and anti-lost interlinking lever end periphery is provided with anti-lost nut.The setting of its anti-board falling and anti-lost spacer, prevents from, because the following partial shell fracture of anti-board falling causes well accident to occur, without the need to anti-lost joint, taking up room little, saving raw material, be easy to processing, anti-lost effective.The utility model reasonable in design, cost is low, is easy to processing, practical.
Description
Technical field
The present invention relates to oil drilling helicoid hydraulic motor technical field, especially relate to a kind of Novel anti-dropping device helicoid hydraulic motor.
Background technology
Helicoid hydraulic motor is a kind of is power with drilling fluid, and fluid pressure can be transferred to the positive displacement mud motor of mechanical energy, its inside needs to be provided with falling-proof apparatus, drops in order to prevent helicoid hydraulic motor parts.Existing falling-proof apparatus is provided with anti-lost joint in connecting rod periphery, anti-lost weak effect, and it is large to take up room, and material consumption is many.
Summary of the invention
The object of the invention is to avoid the deficiencies in the prior art to provide a kind of Novel anti-dropping device helicoid hydraulic motor, thus effectively solve the defect existed in prior art.
For achieving the above object, the technical scheme that the present invention takes is: described Novel anti-dropping device helicoid hydraulic motor, be characterized in comprising the by-pass valve assembly, motor assembly, universal drive shaft assembly and the driving-shaft assembly that are connected successively, falling-proof apparatus is provided with between by-pass valve assembly and motor assembly, described falling-proof apparatus comprises anti-lost connecting rod, anti-lost connecting rod periphery is provided with anti-board falling and anti-lost spacer, and anti-lost interlinking lever end periphery is provided with anti-lost nut.
Described anti-board falling internal diameter is greater than anti-lost connecting rod external diameter, and anti-board falling internal diameter is less than anti-lost nut external diameter.
Described anti-lost spacer is arranged on anti-board falling side, and anti-lost spacer internal diameter is greater than anti-board falling.
The invention has the beneficial effects as follows: described Novel anti-dropping device helicoid hydraulic motor, the setting of its anti-board falling and anti-lost spacer, prevent because the following partial shell fracture of anti-board falling causes well accident to occur, without the need to anti-lost joint, take up room little, save raw material, be easy to processing, anti-lost effective.Reasonable in design of the present invention, cost is low, is easy to processing, practical.
