On axial limiting block, a whole set of seaborne pipeline fixing device is formed after the completion of all installment works, and in workshop
Paint will be protected on shaped steel in spraying；
Third walks, and upper fixing type steel, lower part are fixed shaped steel and be mounted in structural beams, then, by axial limiting block
One end is connect with upper fixing type steel；
4th step, the lateral force size suffered by the pipe shoe according to pipeline, fastens bolt；
5th step is identified the position of acceptance(check)；
Upper fixing type steel and lower part after sea-freight, are fixed shaped steel and are disconnected with structural beams by the 6th step, finally,
Remove a whole set of seaborne pipeline fixing device.
The seaborne pipeline fixing device includes：It is symmetrically mounted on laterally being moved to limit pipeline in structural beams

Limited block.
The upper fixing type steel and lower part, which are fixed between shaped steel and structural beams, is equipped with gasket, and gasket is for increasing shaped steel
Frictional force between contact surface and protection type steel surface paint.
It is symmetrically installed with vertically limited block on the upper fixing type steel, to limit the vertically movable of pipeline；Axis
Axial limited block up and down is symmetrically installed on limited block, to limit the vertically movable of pipeline.
Beneficial effects of the present invention：Due to the adoption of the above technical scheme, not only meeting pipeline, auxiliary is solid temporarily by the present invention
Fixed force request in different directions solves module at sea in transportational process, the restrained problem of the pipeline of module；And
And fire operation is not needed on formal works, it greatly reduces solder type and is fixed temporarily, the paint later stage of module is repaiied
Multiple caused influence.

Specific implementation mode
As shown in Fig. 1-Fig. 4, the present invention uses following steps：
The first step requires according to the force analysis of marine transportation pipeline 10, determines the side of upper fixing type steel 1 and pipe shoe 11
To gap, and determine the axial gap of axial limiting block 4 and pipe shoe 11, meanwhile, it determines on lower position block 6 and axial direction vertically upward
The installation site and quantity of lower position block 7；
Upper fixing type steel 1 and lower part are fixed shaped steel 2 and carry out out bolt hole by second step, and by the one of axial limiting block 4
End is mounted on using welding manner on upper fixing type steel 1, and the other end of axial limiting block 4 installs one block of steel using welding manner
Plate, and bolt hole is opened on the steel plate；Meanwhile lower position block 6 upper fixing type steel 1 will be mounted on using welding manner vertically upward
On, axial limited block 7 up and down is mounted on using welding manner on axial limiting block 4, forms one after the completion of all welding jobs
A whole set of seaborne pipeline fixing device；Shaped steel spraying is painted in workshop, with protection type steel surface, and in appearance
The color of other permanent type components is different from color；
Third walks, and upper fixing type steel 1, lower part are fixed shaped steel 2 and be mounted on existing permanent structure beam 9, also,
It fastens the first bolt and nut pair 3 and arrives maximum value；Then, with the second bolt and nut pair 5 by one end of 4 bolt hole of axial limiting block with
Upper fixing type steel 1 connects, also, fastens the second bolt and nut pair 5；
4th step, the lateral force size suffered by the pipe shoe 11 according to pipeline 10 are special using torque spanner hydraulic spanner etc.
Tool fastens bolt；
5th step applies for checking and examination to installed marine transportation pipeline fixing bracket, is carried out to the position of acceptance(check)
Necessary mark；
6th step after sea-freight, disassembles the first bolt and nut pair 3 and the second bolt and nut pair 5, makes upper fixing type
Steel 1 and lower part are fixed shaped steel 2 and are disconnected with structural beams, finally, remove a whole set of marine transportation pipeline fixing device.
Above-mentioned seaborne pipeline fixing device includes：It is symmetrically mounted on structural beams 9 by the first bolt and nut pair 3
On fix shaped steel 2 to the upper fixing type steel 1 and lower part that limit the lateral movement of pipeline 10, wherein two are symmetrically installed
Axial limiting block 4 is equipped with by the second bolt and nut pair 5 between upper fixing type steel 1, is moved axially to limit pipeline 10
Position.
Above structure beam 9 is already existing permanent component in module, and structural beams 9 are that pipeline 10 and pipe shoe 11 provide forever
Long property support.
Above-mentioned upper fixing type steel 1 and lower part, which are fixed between shaped steel 2 and structural beams 9, is equipped with gasket 8, and gasket 8 is for increasing
Add the frictional force and protection type steel surface paint between shaped steel contact surface.
Vertically limited block 6 are symmetrically installed with using welding manner on above-mentioned upper fixing type steel 1, to limit pipeline
10 it is vertically movable；Axial limited block 7 up and down is symmetrically installed with using welding manner on axial limiting block 4, to limit pipeline
10 it is vertically movable, according to construction physical condition, lower position block 6 and axial limited block 7 up and down vertically upward, it is only necessary to which it is installed
One of can be realized limitation pipeline it is vertically movable.
By adjusting the upper fixing type steel 1 in the present invention, axial limiting block 4, lower position block 6 vertically upward, in axial direction
The mobile limitation on the different directions to pipeline 10 may be implemented in gap size between lower position block 7 and pipe shoe 11.
The above described is only a preferred embodiment of the present invention, be not intended to limit the present invention in any form, it is all
It is that any simple modification, equivalent change and modification made by above example are still fallen within according to the technical essence of the invention
