Abstract
This utility model relates to oil drilling cementing technology field, particularly relates to a kind of rotor falling-proof apparatus, including connecting rod rotor, stator case, anti-lost dish, anti-lost packing ring and anti-lost nut；Described connecting rod rotor is placed in described stator case, a circular bead surface tilted is processed inside one end of described stator case, anti-lost dish is fixed at circular bead surface, described anti-lost packing ring is fixed on speed by described anti-lost nut and searches the end of connecting rod rotor, and the external diameter of anti-lost packing ring is more than the internal diameter of described anti-lost dish.A circular bead surface tilted is processed inside one end of stator case, anti-lost dish anti-position just at the circular bead surface that stator case is processed, eliminate these parts of anti-lost housing in conventional anti-lost assembly, greatly save raw material and processing cost.
Description
Technical field
This utility model relates to oil drilling cementing technology field, particularly relates to a kind of rotor falling-proof apparatus.
Background technology
At present, oil, natural gas drilling engineering in use helicoid hydraulic motor, the purpose of its anti-lost assembly prevents exactly because of down hole problem or because misoperation causes screw motor and drops in down-hole so that lower portion disconnects accidentally.Conventional traditional anti-lost be all to use these parts of anti-lost housing.Use the shortcoming of anti-lost housing be raw material and processing cost higher, complexity is installed.
Utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and provides a kind of rotor falling-proof apparatus, and simple in construction saves processing cost.
This utility model for achieving the above object, by the following technical solutions:
A kind of rotor falling-proof apparatus, it is characterised in that: include connecting rod rotor, stator case, anti-lost dish, anti-lost packing ring and anti-lost nut；Described connecting rod rotor is placed in described stator case, a circular bead surface tilted is processed inside one end of described stator case, anti-lost dish is fixed at circular bead surface, described anti-lost packing ring is fixed on the end of described connecting rod rotor by described anti-lost nut, and the external diameter of anti-lost packing ring is more than the internal diameter of described anti-lost dish.
The beneficial effects of the utility model are: compared with prior art, a circular bead surface tilted is processed inside one end of stator case, anti-lost dish anti-position just at the circular bead surface that stator case is processed, eliminate these parts of anti-lost housing in conventional anti-lost assembly, greatly save raw material and processing cost.Moreover, just because of eliminating anti-lost housing, this has threaded parts, also eliminates a screw rod and falls the hidden danger of well.And connecting rod rotor, these novelty parts, not only in processing, have convenience than conventional part, eliminate the processing of threaded one end, eliminate another item potential safety hazard, also eliminate anti-lost connecting rod and this process of rotor simultaneously in an assembling process, play the effect saving certain time.While innovating original anti-lost combination, remaining again anti-lost packing ring, its effect is to effectively reduce the back-off probability that anti-lost nut exists.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings and preferred embodiment describe in detail detailed description of the invention of the present utility model.As it is shown in figure 1, a kind of rotor falling-proof apparatus, including connecting rod rotor 1, stator case 2, anti-lost dish 3, anti-lost packing ring 4 and anti-lost nut 5；Described connecting rod rotor is placed in described stator case, a circular bead surface tilted is processed inside one end of described stator case, anti-lost dish is fixed at circular bead surface, described anti-lost packing ring is fixed on the end of described connecting rod rotor by described anti-lost nut, and the external diameter of anti-lost packing ring is more than the internal diameter of described anti-lost dish.
As anti-lost housing in the effect that anti-lost dish is played assembly anti-lost with routine.A circular bead surface tilted is processed inside one end of stator case, anti-lost dish anti-position just at the circular bead surface that stator case is processed, eliminate these parts of anti-lost housing in conventional anti-lost assembly, greatly save raw material and processing cost.Moreover, just because of eliminating anti-lost housing, this has threaded parts, also eliminates a screw rod and falls the hidden danger of well.And connecting rod rotor, these novelty parts, not only in processing, have convenience than conventional part, eliminate the processing of threaded one end, eliminate another item potential safety hazard, also eliminate anti-lost connecting rod and this process of rotor simultaneously in an assembling process, play the effect saving certain time.While innovating original anti-lost combination, remaining again anti-lost packing ring, its effect is to effectively reduce the back-off probability that anti-lost nut exists.
The above is only preferred implementation of the present utility model; it should be pointed out that, for those skilled in the art, on the premise of without departing from this utility model principle; can also make some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
