Abstract
A crescent rod elevator includes a main body, a handle, a set screw, lifting lugs, a big crescent, a small crescent and a locking block, wherein the whole body is a cut body formed by superposing the centers of a cylinder and a cuboid; the lifting lugs are arranged on two sides; a safety pin hole is arranged in each of the two ends; a U-shaped slot is arranged in middle; a flared opening is arranged at the top of the U-shaped slot; the small crescent is arranged outside the lower part of the U-shaped slot; a crescent cavity s arranged outside the small crescent; and the big crescent is mounted in the crescent cavity. The crescent rod elevator has the benefits as follows: the crescent rod elevator has a novel structure, is safe and reliable, is convenient to operate, and can elevate different specifications of common pumping rods; the flared opening matched with the bearing conical surface of the pumping rod can prevent the pumping rod from slipping in case of higher stress; the crescents are arranged below the elevator, and are only used for locking the pumping rod and preventing the pumping rod from slipping as the conical surface rather than the crescents is stressed when the pumping rod bears the load; and further, the locking block is arranged at the bottom of the crescents, and can prevent the crescents from dropping from the elevator in case that the handle drops, so as to ensure the personal safety of the operating personnel.
Description
Technical field
The underground work suspension sucker rod that
the utility model relates to petroleum industry trips out the special-purpose workover tool with G.I.H by root in the oil well, particularly is a kind of month dentition formula rod elevator.
Background technology
pumpingh well is in operation process, and when tripping out, the special-purpose elevator of sucker rod is one of main instrument with the little hook of sucker rod special use to sucker rod at G.I.H.The construction of underground work at present when playing the lower sucker rod tubing string, is to adopt flapper-type rod elevator and the little hook of sucker rod to be used to accomplish.Method is that the suspension ring on the hook are taken off, and hangs up the little hook of sucker rod that connects with wire rope, and the arm that hooks rod elevator when removing is accomplished rountrip.Mainly there is problem in sucker rod when being hooked in for a short time and using, and the one, little hook insurance is non-standard component, yielding damage and lose safety effect.The 2nd, wire rope is in long-term the no detection means in back of using, and is prone to produce disconnection, the generation of wire clips breakage problem when bearing big load.The weight that rod elevator leans on the elevator plane to bear sucker rod, rod elevator fastens, discharges the mode of sucker rod, is to adopt the flapper-type valve, controls valve through spring force and is in fastening position all the time, blocks sucker rod and does not drop out.Mainly there is problem in rod elevator in use, and the one, if spring by crude oil and other booty jam, just spring can't return, and causes sucker rod to deviate from, there is potential safety hazard.The 2nd, when bearing big pulling force, elevator is prone to deflection takes place, and the accident that causes stretch bending sucker rod and sucker rod to deviate from takes place.The 3rd, rod elevator is a non-standard component, and no use standard and standard can't be carried out conventional sense.Thereby prior art can not solve the problems of the technologies described above preferably.
Summary of the invention
The purpose of
the utility model is exactly the above-mentioned defective that exists to prior art, and a kind of month dentition formula rod elevator is provided.
the utility model technical scheme comprises: body, handle, dog screw, hanger, big crescent moon, little crescent moon, lock dog; Its month, the dentition formula rod elevator was cylinder and cuboid center stack cutting body; Both sides are hangers, and hanger hole and suspension ring match, and are convenient to set out.Two ends respectively are provided with an insurance pin-and-hole, insert safety plug during use, and the center is " U " type groove; " U " type groove top is provided with horn mouth, make sucker rod get into " U " type groove after, sucker rod cone termination is sitting on the horn mouth; Bottom " U " type groove is outward little crescent moon, and little crescent moon is outward a month teeth cavity, in month teeth cavity big crescent moon is housed; Big crescent moon can circumferentially≤60 ° back and forth rotate in moon teeth cavity, and handle passes slideway and connects with big crescent moon end thread, and lock dog is installed in bottom moon teeth cavity; With big crescent moon location, dog screw screws in the tapped blind hole of lock dog and fixes.
Handle in
above-mentioned month dentition formula rod elevator is made up of kink, center-pole, spring, and kink is a cylindrical shape, and cylindrical is three grades of ladders centre annular knurl structures, and spring housing passes from the kink center on threaded center-pole.
Slideway in
above-mentioned month dentition formula rod elevator is a circular arc, and two ends are provided with the circular hole greater than chute width, owing to pin handle.
The beneficial effect of
the utility model is: novel structure, and safe and reliable, easy to operate, can accomplish, the time operation of pumpingh well different size sucker rod commonly used; Last planar design is for carrying the horn mouth that the conical surface matches with sucker rod, can prevent that sucker rod is in stressed not slippage when big; The crescent moon design is below elevator, and crescent moon does not stress by the conical surface is stressed during the sucker rod carrying, only plays the effect that sucker rod is not deviate from of pinning; Lock dog is placed in crescent moon bottom, it can in case when handle comes off crescent moon in elevator, drop, guarantee operator's personal safety.
