Abstract
The invention relates to a safe oil pipe elevator device which is a tool used for clamping an oil pipe to finish stripping the oil pipe in the underground operation of an oil field. The safe oil pipe elevator device is characterized in that opening grooves communicated with side openings are arranged on the side openings of two sides of an elevator main body and the lower part of round holes communicated with the side openings; the opening grooves are internally provided with rotating elevator pins 8 fixed by fixed screw pins 11 of fixed screw holes; and button switches 13 matched with the rotating elevator pins 8 are arranged on the upper side of the side openings of the elevator, so the problems that the elevator pins are difficult to be inserted and pulled and fall to injure people. A crescent pin 3 is a built-in countersunk screw and is serially inserted by a round hole of the cavity of the elevator main body 1; after the crescent pin 3 is matched with crescent countersunk threads, a handle 4 is sleeved into the crescent pin 3, and a handle spring 5 is filled into the handle 4; a crescent screw cap 6 is arranged in the crescent pin 3 and is stopped by a cotter pin 7, so that the breaking and falling phenomena of the crescent pin 3 can be avoided; a suspension arm (upper arm) of the elevator main body is longer than a lower arm, and a lifting ring can naturally enter the cavity of the suspension arm (upper arm) when the oil pipe is lifted and can furthest reduce single lifting ring accidents. The field use verifies that the safe oil pipe elevator device has the advantages of convenient operation, safety, reliability and durability.
Description
Relate to the field:
The present invention is used for oilfield downhole operation, blocks oil pipe, finishes a kind of power tool that removes the oil pipe operation.
Background technology:
At present, in oilfield downhole operation is produced, widely used pipe elevator, employing be inserted-link type elevator pin, the elevator globality is poor, poor stability uses trouble.When removing the oil pipe operation, latch, write off trouble often exists and inserts not Shang pin or the pin phenomenon slotting not in place and the damage failure phenomenon of elevator pin, collapses and buckles and scrape, when bumping phenomenon, causes oil pipe or elevator, the elevator pin casualty accident that drops oil pipe occurring.The crescent moon pin fixedly be to fix with fixing spiral pin after the threaded engagement, when screw thread tightened, the probability that steady pin just in time can be fixed was very low, in use easily caused thread damage; Fixed processing pin-and-hole on limited crescent moon pin diameter, make the working strength of crescent moon pin be subjected to bigger influence, often run in construction that the crescent moon pin is disconnected, crescent moon pin screw thread and corresponding nut damage phenomenon, caused the casualty accidents that drop such as oil pipe, crescent moon, crescent moon pin, handle.When playing the tubing hanger suspension ring, be from the elevator body side opening hang into because the limitation of side opening easily causes the single-ring accident.
Technology contents:
The objective of the invention is to solve the above weak point of pipe elevator, provide a kind of elevator body, crescent moon, crescent moon pin, handle, elevator pin etc. as a whole, and have easy to operate, safe and reliable oil pipe elevator device.
The present invention is achieved in that
Comprise elevator body 1, crescent moon 2, crescent moon pin 3, handle 4, handle spring 5, crescent moon pin nut 6, cottor pin 7, rotation elevator pin 8, torsion spring 9, spring pad 10, fixedly spiral pin 11, stage clip 12, press button 13, button plate washer 14, button plate washer fixed screw 15 compositions.The circular hole that there is side opening the both sides of elevator body 1 and is connected with side opening, the transverse opening groove that is communicated with side opening is arranged at the bottom of circular hole, the rotation elevator pin of fixing by the fixedly spiral pin 11 of fixing threaded hole 8 is arranged in the open slot, rotation elevator pin 8 is " L " type, the upside of elevator side opening has and rotation elevator pin 8 corresponding groove, the circular hole that is horizontally installed with stage clip 12, press button 13 of groove, there is the groove that button plate washer 14 is installed in the circular hole outside, and button plate washer 14 is fixed on the elevator body 1 by button plate washer fixed screw 15.Crescent moon pin 3 is built-in, and promptly the countersunk head spiral pin seals in by the circular hole of elevator body 1 inner chamber, after the counterbore threaded engagement with crescent moon, handle 4 is inserted in crescent moon pin 3, handle spring 5 is filled in the handle 4 again, and crescent moon pin nut 6 is installed, and with cottor pin 7 retainings.
The present invention has also adopted following technical scheme:
Fixedly spiral pin 11 is equipped with torsion spring 9 with rotation elevator pin 8 places, and the state that rotation elevator pin 8 is in out all the time is convenient to pluck, hang suspension ring.
Elevator suspension arm (upper arm) is longer than the rotation external diameter of rotation elevator pin 8, even cause the elevator rotation on oil pipe, during shackle, also can not run into the elevator pin, has increased safety; The elevator underarm is shorter than elevator suspension arm (upper arm) and is shorter than simultaneously or equals to rotate elevator pin 8 internal diameters.
The invention has the advantages that:
1, elevator body and elevator pin are as a whole, so promptly are convenient to operation and help safety again.
2, elevator body suspension arm (upper arm) is longer than underarm, and when carrying the tubing hanger suspension ring, suspension ring enter suspension arm (upper arm) inner chamber naturally, is convenient to hang the suspension ring construction, has reduced the single-ring accident to greatest extent.
3, the crescent moon pin is that the countersunk head screw rod from inside to outside screws, and has avoided crescent moon pin disconnected and crescent moon pin screw thread and corresponding nut damage phenomenon.
Description of drawings
Accompanying drawing 1 is a structural front view of the present invention
Accompanying drawing 2 is a structure vertical view of the present invention
Concrete enforcement:
The present invention will be further described below in conjunction with accompanying drawing:
As shown in the figure, key dimension of the present invention is: main body 1 length overall 440mm, brachium 372mm under the high 205mm; Be equipped with wide 22mm open slot in distance main body upper part, be used for installing rotation elevator pin 8; Rotation elevator pin diameter is 16mm; The press button diameter is 23mm, length overall 50mm; Stage clip 12 diameters are 22mm, long 20mm; Crescent moon pin diameter is 12mm, and length is 84mm.When not hanging suspension ring, the position that rotation elevator pin 8 is in out under the effect of torsion spring 9 all the time, hang up suspension ring after, rotate elevator pin 8 by hand, rotation elevator pin 8 tops are entered in the press button 13, rotation elevator pin 8 is lockable under the effect of stage clip 12.When plucking suspension ring, with the have gentle hands switch 13 that touches the button, rotation elevator pin 8 is opened under the effect of torsion spring 9 automatically.Rotation elevator pin 8 and press button 13 are horizontally set, and rotation elevator pin 8 external diameters are less than elevator suspension arm (upper arm), can not be subjected to oil pipe and collapse and buckle and scrape, bump influence.Use checking by the scene, this safe oil pipe elevator device is easy to operate, and significantly improve application life, promptly avoided construction accident, guaranteed constructor's personal safety again.
