Description
Technical field
The present invention relates to oil drill rocker elevator apparatus.
Background technology
Oil drill rocker elevator apparatus is a kind of instrument for tubing such as drilling rod of slinging, oil pipe, sleeve pipes, and it is suspended on inside the suspension ring of lifting system hook both sides, in order to well is tripped out or under enter drilling tool and oil pipe, the operation of sleeve pipe.
Elevator apparatus, when drilling and repairing well operation, is used for directly hanging the rig tool of tubing string, upper connection suspension ring, and different apertures hangs different tubing strings.Elevator often bears the weight of all tubing strings in the drive system of top, also plays irreplaceable effect, can be divided into rod elevator, drill pipe elevator, casing elevator and pipe elevator by the tubing string difference hung during taking over and unloading pipe.
During upper pipe, tubing string can be delivered to suitable position by mechanical arm, open elevator to be locked by tubing string, after the position of tubing string is well placed by elevator, it is positioned at the upper shackle device driven on top can be screwed by drilling rod, during unloading lower tubular column, top is driven drill rod fastener dismount, then by elevator, tubing string is delivered to suitable position and is removed tubing string by mechanical arm.
The major defect of existing elevator apparatus is: elevator apparatus includes elevator apparatus body construction, the tubular column structure body that elevator apparatus body construction that is one can close with opening and closing, this tubular column structure body is provided with arc otic placode, two arc otic placodes are clamped on the connection post of centralizer, the connection post of centralizer is necessary for column structure, so arc otic placode clasps the connection post of centralizer, such structure needs bigger chucking power, need to use frame for movement to be connected on otic placode by connection post, and this spline structure easily skids, the most dangerous.
Summary of the invention
It is an object of the invention to provide a kind of oil drill rocker elevator apparatus, the present invention changes the otic placode structure of elevator apparatus, can solve otic placode structure and be connected the problem that post connects skidding with centralizer.
nullThe purpose of the present invention is achieved through the following technical solutions: oil drill rocker elevator apparatus，Including drill pipe elevator body，2 centralizer attachment means it are provided with on bar elevator body，Each centralizer attachment means is mainly connected otic placode by 2 centralizers being arranged on elevator body lateral surface and the chain structure being arranged on 2 centralizers connection otic placodes is constituted，Chain structure and 2 centralizers connect formation one between otic placode and connect the cavity of post for clamping centralizer，Centralizer connects post and inserts in this cavity，Wherein chain structure includes the chain rotating shaft that multiple axis is parallel to each other，Connect between adjacent two chain rotating shafts and have chain connecting plate，Wherein 2 chain rotating shafts at chain structure two ends are connected respectively on centralizer connection otic placode，Chain rotating shaft runs through centralizer and connects otic placode，The axis that the axis of chain rotating shaft connects post with centralizer is parallel.
It is to be realized by said structure that the present invention solve otic placode structure be connected post to connect, with centralizer, the problem skidded, its principle realized is: utilize the chain connecting plate of chain structure, wherein chain connecting plate is crimped on the outer surface of clamping centralizer connection post, when clamping centralizer connection post and being polygon, putting of chain connecting plate is shaped as polygon spill, so clamping after hold centralizer connect post can not rotate, the problem that traditional structure skids can be avoided.Wherein chain connecting plate is attached by chain rotating shaft, middle chain connecting plate can be rotated by random carrying out, the chain structure constituting the enclosuring structure between centralizer connection otic placode can form change along with the structure holding centralizer connection post, so, this device be adapted to a variety of formation hold centralizer connect post, such as hold centralizer connect post be rectangle or polygon or triangle oval or circular.Preferably, hold centralizer connecting post is rectangle or polygon.This device can also improve centralizer and connect the stress state of otic placode, the centralizer of traditional structure connects otic placode stress and is mainly the otic placode in position, upside, stress distribution becomes sector, this otic placode easily ftractures, and the structure of the present invention, stress state can be improved, pass through chain structure, the centralizer that power dispersion is delivered to lower section connects on otic placode, this simultaneously the chain connecting plate in chain device also can disperse to bear certain stress, this makes the centralizer of upper side coil in this device connect otic placode and is difficult to cracking.
Preferably, the elevator body of the present invention includes that arcuate member is closed in elevator body arcuate member and elevator opening and closing, elevator body arcuate member closes arcuate member by main shaft and elevator opening and closing and constitutes a tubulose elevator body that can close with opening and closing, main shaft runs through body arcuate member, and elevator opening and closing is closed the side of arcuate member and is connected with main shaft.So elevator body simple in construction, easy to make, easy to operate.
Preferably, elevator body arcuate member and elevator opening and closing are closed and are both provided with opening and closing conjunction otic placode on arcuate member, and 2 opening and closings are closed and connected by opening and closing conjunction screw rod between otic placodes.Rotate elevator opening and closing and close arcuate member, main shaft is rotated, and elevator opening and closing is closed arcuate member and is rotated around main shaft, after turning an angle, after arcuate member composition tubular column structure is closed in elevator body arcuate member and elevator opening and closing, insert opening and closing conjunction screw rod 2 opening and closings of connection and close otic placode.Screw opening and closing and close screw rod so that arcuate member clamping oil drill rocker or petroleum pipeline or sleeve pipe are closed in elevator body arcuate member and elevator opening and closing.
Preferably, centralizer connects the cross section of post is oval or circular or polygon.
It is an advantage of the current invention that: simple in construction, low cost, easy to operate, shorten the engineering time, otic placode structure can be solved and be connected the problem that post connects skidding with centralizer.
