Abstract
The utility model belongs to the technical field of marine oil drilling and extracting equipment, and particularly relates to a hydraulic equipment mounting tool for feeding or taking out of oil drilling and extracting equipment in oil drilling and extracting operation. The mounting tool consists of a rotating joint, a frame inner drum, a piston, an outer barrel, a locking piece mechanism, a supporting barrel and a spring. The rotating joint is screwed on the frame inner barrel; the outer barrel is sleeved on the frame inner barrel; a piston is mounted between the outer barrel and the frame inner barrel; the locking piece mechanism is sleeved on the piston, and is supported and positioned by the supporting barrel sleeved on the outer side at the lower part of the frame inner barrel; a hydraulic extruding oil hole A is formed on the outer barrel; and a hydraulic resetting oil hole B is simultaneously formed on the frame inner barrel. In the utility model, the piston is driven hydraulically, and the locking piece mechanism is extruded to slide according to the designed position through an inclined plane, so as to achieve the locking state or the unlocking state, thereby achieving the safe and quick connection between the mounting tool and the device, satisfying the coordination work of the designed tool and heavy objects to be lifted, and achieving the purposes of conveniently operating, and safely and reliably lifting the device.
Description
Technical field
The utility model belongs to sea oil drilling and production equipment technology field, is exactly specifically when installation and removal petroleum drilling and mining equipment, sends into the hydraulic tool with extraction device.
Background technology
At present, the mode of sending into extraction device commonly used is in the petroleum drilling and mining equipment: utilize boom hoistings such as rig trip crane system, special-purpose loop wheel machine, pneumatic or hydraulic wireline winch, adopting wire rope or other mechanical means, is to tie up equipment, it can be sent into extraction device arrive the target location.The common problem that these modes exist: the one, working space is big, be to tie up the process more complicated; The 2nd, stand is difficult to accurate control, and is poor to positivity; The 3rd, poor, the inefficiency of security reliability.
Summary of the invention
The utility model purpose is a kind of fluid pressure type equipment erecting tools of design, is used to send into and to take out oil drilling and extracting equipment not only quick and convenient, but also safe and reliable in the petroleum drilling and mining operation to satisfy.
Briefly, in the petroleum drilling and mining operation, be used to send into and take out a kind of fluid pressure type equipment erecting tools of oil drilling and extracting equipment, it has hydraulically powered piston, with the equipment connecting end can be sealed or the lock dog mechanism of throwing off is enclosed within on the piston and strut or shrink by piston area extruding lock dog mechanism and realize lock dog mechanism's slippage and driving arrangement connecting end and lock dog mechanism is sealed or disengagement
Specifically, described a kind of fluid pressure type equipment erecting tools is made up of bucket, piston, outer bucket, lock dog mechanism, barrel support, spring in swivel joint, the frame; Swivel joint is screwed on the interior bucket of frame, outer casing is in frame on the bucket and piston is housed between the two, lock dog mechanism is enclosed within on the piston and the barrel support that is enclosed in the outside, bucket bottom in the frame supports the location, and the oilhole A that has the hydraulic pressure extruding outside on the bucket has the hydraulic pressure oilhole B that resets simultaneously on the bucket in frame.
Piston is stairstepping or drum shape, as long as its profile can satisfy and push lock dog mechanism and it is opened or shrink.
Described lock dog mechanism is that the four-section lock piece is formed or six sections or other multistage, and lock dog is trapezoidal formula structure or a tooth or polydonita formula triangular form, trapezoidal, any one form of rectangle; Spring be four sections or one whole section spring along circumferential ring around lock dog; Spring is shell fragment or other elastomeric material.The lock dog structure function is the extruding that relies on itself and piston contact surface, opens or shrinks and combine with the equipment connecting end or throw off.The utility model is recommended the inclined-plane contact structures of piston and lock dog, and single structure that other realizes the utility model purpose is also in the present utility model thought protection and so on.
There is boss on the swivel joint top.By the setting of boss, formed and crossed a neck, the neck that the elevator in the rig trip crane system clamps swivel joint carries out work.
The utility model advantage is: in installation and removal petroleum drilling and mining when equipment, and can be not only quick and convenient, but also safe and reliable sending into and extraction device.Compactness rational in infrastructure, simple, it adopts hydraulic drive piston, by of the position slippage of inclined-plane extruding lock dog mechanism by design, reach state sealed or that throw off, thereby realize that erecting tools fast is connected with device security, satisfy design tool and hoisting heavy co-ordination, realized the purpose of simple operation, safe and reliable lifting means.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model lock dog structural scheme of mechanism.
The figure number explanation:
The outer bucket of bucket 3---piston 4---in the 1---swivel joint 2---frame
The 5---lock dog 6---of mechanism barrel support 7---spring 8---equipment connecting end.
The specific embodiment
As shown in Figure 1, the utility model mainly is made up of component such as bucket 2, piston 3, outer bucket 4, lock dog mechanism 5, barrel support 6, spring 7 in swivel joint 1, the frame.There is boss on swivel joint 1 top and is screwed on the interior bucket 2 of frame, outer bucket 4 is enclosed within on the interior bucket 2 of frame and piston 3 is housed between the two, lock dog mechanism 5 is enclosed within on the piston 3 and the barrel support 6 that is enclosed in the outside, bucket 2 bottoms in the frame supports the location, and the oilhole A that has the hydraulic pressure extruding outside on the bucket 4 has the hydraulic pressure oilhole B that resets simultaneously on the bucket 2 in frame.Piston 3 be stairstepping.The four-section lock piece constitutes lock dog mechanism 5 by spring serial connection, and lock dog is trapezoidal formula structure or a tooth or polydonita formula triangular form, trapezoidal, any one form of rectangle.
The utility model course of work is: 1, in implementing kit and equipment connecting end 8 connection procedures, at first utilize elevator in the rig trip crane system to clamp the neck of swivel joint 1, then this instrument is vertically transferred to the equipment connecting end 8 of its upper side to be installed, the trapezoid boss and the location of the trapezoidal groove on the equipment connecting end 8 of lock dog mechanism 5 are aligned, A oilhole oil-feed B oilhole oil return in showing by accompanying drawing this moment, driven plunger 3 moves downward, the inclined-plane of piston 3 extruding lock dog mechanism 5 along radially the upper surface of barrel support 6 to around the slippage expansion, slide into till barrel support 6 boss face contact up to piston 3, make in the dovetail groove on the complete access arrangement connecting end 8 of trapezoid boss of lock dog mechanism 5, thereby realize being connected between erecting tools and the equipment, and finally reach and send into or the purpose of extraction device.
In implementing kit and equipment connecting end 8 disconnecting process, the oil return of B oilhole oil-feed A oilhole, piston 3 is moved up, then lock dog mechanism 5 it withdraws from dovetail groove on the equipment connecting end 8 in pulling under the effect of spring 7 restoring forces, and finally realize that automatically release throws off.
