Technical field
The utility model is related to a kind of separate modular grinding cutter devices for being suitable for marine pit shaft and removing cutting, especially
It is related to a kind of portable pit shaft cutter device, belongs to ocean engineering field.
Background technology
With deepening continuously for marine petroleum development, the offshore field that part early stage goes into operation stops production because oil-free can adopt,
Support pit shaft loses original function and is thrown aside, and is distributed on navigation channel, huge hidden danger is brought to sail and construction safety,
There is an urgent need for remove；Completely design enlistment age, the evaluated platform that cannot be on active service, according to National Bureau of Oceanography《Offshore platform is thrown aside
Manage Tentative Measures》Regulation, it is necessary to all remove, 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 use 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.
Utility model content
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 purpose of this utility model are to provide a kind of portable pit shaft cutter device, can not employ brill/
Workover rig independently realizes pit shaft cutting operation under conditions of being supported, and without employing the support of brill/workover rig, reduces sea
Upper pit shaft cutting construction cost and difficulty improve the feasibility of marine pit shaft cutting.
A kind of portable pit shaft cutter device of the utility model, is achieved through the following technical solutions：
A kind of portable pit shaft cutter device, including high-pressure hydraulic pump, high-pressure hose, the device that is fixedly clamped, hydraulic rotator and
Cutter head；High-pressure hydraulic pump is connected to by high-pressure hose and is fixedly clamped on device, and hydraulic rotator is hung under the device that is fixedly clamped
Side, and be fixedly clamped device constitute axial limiting, rotate in a circumferential direction cooperation, cutter head is installed on hydraulic rotator lower part output shaft
On.
The device peripheral distribution that is fixedly clamped has 2 or more claws, top to be equipped with the nozzle being connect with high-pressure hose,
The hydraulic rotator periphery is equipped with screw wing, and the cutter head peripheral distribution has 2 or more cutting sheets.
It is fixedly clamped the claw of device periphery and the cutting sheet of cutter head periphery is retractable structure.
The stretching structure includes elastic support structure or cone rotatable support structure.
The advantageous effect of utility model：The utility model is related to a kind of portable pit shaft cutter device, have structure it is tight
It gathers, the feature that independent cutting operation ability is strong and easy to operate.The dependence to brill/workover rig is avoided, offshore well is reduced
Cylinder cutting cost and difficulty improve the feasibility of marine pit shaft cutting.
Description of the drawings
Fig. 1 is a kind of portable pit shaft cutter device schematic diagram of the utility model.

Specific implementation mode
The utility model 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 involved by the utility model, specific implementation mode are：Just
It includes high-pressure hydraulic pump 1, high-pressure hose 2, the device 3 that is fixedly clamped, hydraulic rotator 4 and cutter head to take formula pit shaft cutter device mainly
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 device that is fixedly clamped
3 lower section, and be fixedly clamped device 3 constitute axial limiting, rotate in a circumferential direction cooperation, cutter head 5 is installed on 4 lower part of hydraulic rotator
On output shaft.
Further, 3 peripheral distribution of device that is fixedly clamped has 4 claws, top to be equipped with the spray being connect with high-pressure hose 2
Mouth, 4 periphery of the hydraulic rotator are equipped with screw wing, and 5 peripheral distribution of the 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.
One of portable pit shaft cutter device characteristic feature of the utility model is that cutter head 5 is installed on hydraulic rotator
On 4 output shafts, 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 revolve
