Description
Technical field
The present invention relates to a kind of separate modulars for removing cutting suitable for marine pit shaft to be ground cutter device, in particular to
A kind of portable pit shaft cutter device, belongs to ocean engineering field.
Background technique
With deepening continuously for marine petroleum development, the offshore field that part early stage goes into operation stops production because of oil-free adopt,
Support pit shaft loses original function and is thrown aside, and is distributed on navigation channel, brings huge hidden danger to sail and construction safety,
It needs to remove；The enlistment age is completely designed, the evaluated platform that cannot be on active service, " offshore platform is thrown aside according to National Bureau of Oceanography
Manage Tentative Measures " regulation, it is necessary to it all removes, the structure etc. in residual seabed should be cut to 4 m or less of seabed surface.
The pit shaft thrown aside in marine petroleum development, periphery are usually surrounded by jacket platform, conventional external cutting method
Pit shaft difficult to realize is removed.At present frequently with method be using brill/workover rig carry out dismounting operation, Gu that is, using drilling machine+
Determine well drilling pipe column+cutting tool, using the drilling machine function of mobile brill/workover rig, well drilling pipe column and cutting tool are transferred
Certain depth in pit shaft drives well drilling pipe column and the cutting tool of bottom to realize cutting for pit shaft by the rotation of Rotary table for drilling machine
It cuts.But because independent degree is low, cutting cost is high, platform moving and the restriction of complicated factor in place, the implementation of this kind of mode by
It is restricted to great.
Summary of the invention
For mobile brill/workover rig drilling machine independent degree it is low, cutting cost is high, platform moving and in place complicated
The problems such as restriction of factor, the object of the present invention is to provide a kind of portable pit shaft cutter devices, can not employ brill/well workover
Equipment independently realizes pit shaft cutting operation under conditions of being supported, and without employing the support of brill/workover rig, reduces offshore well
Cylinder cutting construction cost and difficulty improve the feasibility of marine pit shaft cutting.
A kind of portable pit shaft cutter device of the invention, is achieved through the following technical solutions:
A kind of portable pit shaft cutter device, including high-pressure hydraulic pump 1, high-pressure hose 2, the device 3 that is fixedly clamped, hydraulic rotator 4 and
Cutter head 5；High-pressure hydraulic pump 1 is connected to by high-pressure hose 2 and is fixedly clamped on device 3, and the hanging of hydraulic rotator 4 is being fixedly clamped
The lower section of device 3, and constitute with the device 3 that is fixedly clamped that axial limiting, rotate in a circumferential direction cooperation, cutter head 5 is installed under hydraulic rotator 4
On portion's output shaft.
3 peripheral distribution of device that is fixedly clamped has 2 or more claws, and top is equipped with the spray connecting with high-pressure hose 2
Mouth, 4 periphery of hydraulic rotator are equipped with screw wing, and 5 peripheral distribution of cutter head has 2 or more cutting sheets.
The cutting sheet of 5 periphery of claw and cutter head of 3 periphery of device of being fixedly clamped is retractable structure.
The stretching structure includes elastic support structure or cone rotatable support structure.
Advantageous effect of the invention: a kind of portable pit shaft cutter device of the present invention, have it is compact-sized, independently cut
Cut the strong and easy to operate feature of work capacity.It avoids to the dependence of brill/workover rig, reduces marine pit shaft cutting cost
And difficulty, improve the feasibility of marine pit shaft cutting.
Detailed description of the invention
Fig. 1 is a kind of portable pit shaft cutter device schematic diagram of the invention.
1 high-pressure hydraulic pump, 2 high-pressure hoses, 3 are fixedly clamped device, 4 hydraulic rotators, 5 cutter heads.
Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, a kind of portable pit shaft cutter device according to the present invention, specific embodiment are as follows: portable
Pit shaft cutter device mainly includes high-pressure hydraulic pump 1, high-pressure hose 2, the device 3 that is fixedly clamped, hydraulic rotator 4 and cutter head 5 etc..
Wherein:
High-pressure hydraulic pump 1 is connected to by high-pressure hose 2 and is fixedly clamped on device 3, and hydraulic rotator 4 is hung in the case where being fixedly clamped device 3
Side, and be fixedly clamped device 3 constitute axial limiting, rotate in a circumferential direction cooperation, it is defeated that cutter head 5 is installed on 4 lower part of hydraulic rotator
On shaft.
Further, 3 peripheral distribution of device that is fixedly clamped has 4 claws, and top is equipped with the spray connecting with high-pressure hose 2
Mouth, 4 periphery of hydraulic rotator are equipped with screw wing, and 5 peripheral distribution of cutter head has 4 cutting sheets.
The cutting sheet of 5 periphery of claw and cutter head of 3 periphery of device of being fixedly clamped is retractable structure.The flexible knot
Structure includes elastic support structure or cone rotatable support structure.
Portable pit shaft cutter device characteristic feature of the invention first is that cutter head 5 to be installed on hydraulic rotator 4 defeated
On shaft, is rotated by 4 output shaft of high pressure water-driven hydraulic rotator that high-pressure hydraulic pump 1 provides, cutter head 5 is driven to rotate reality
The cutting of existing pit shaft.The device 3, the claw jam-packed well for the device 3 that is fixedly clamped second is that the top installation of cutting pipe string is fixedly clamped of its feature
The vertical and axial restraint of cutting pipe string is realized after barrel.
The use process of portable pit shaft cutter device according to the present invention is described:
1) connection cutting pipe string, is followed successively by that cutter head 5, hydraulic rotator 4, be fixedly clamped device 3, high-pressure hose from bottom to top
2, high-pressure hydraulic pump 1.
2) cutting pipe string is transferred to pit shaft certain depth, open the claw for the device 3 that is fixedly clamped and holds out against well bore wall, it is real
The vertical and axial restraint for now cutting pipe string prevents the cutting vertical downslide of pipe string, and provides fulcrum for the rotation of cutting tool 5.
3) start high-pressure hydraulic pump 1, driving 4 output shaft of hydraulic rotator rotation, and cutting tool 5 is driven to rotate, realize well
Cylinder cutting.
