Abstract
A separating type son-mother tube clamp comprises a base, a top protection cap, a son tube limiting clamp and a binding belt. The base is used for connecting a son tube with a mother tube. The top protection cap can be in butt connection with the inner side and the outer side of the base. The son tube limiting clamp is embedded into the base. The base and the top protection cap are connected together through the binding belt. The upper end of the base is provided with an arc limiting groove used for containing the son tube limiting clamp, the lower end of the base is provided with an arc limiting groove used for being matched with a seabed pipeline, and the curvature of the outer arc surface of each arc groove is larger than that of the inner arc surface. According to the separating type son-mother tube clamp, the son tube and the mother tube can be connected, meanwhile, adjustment can be carried out according to changes of the distance between the son tube and the mother tube, only one clamp is used for being applicable to connection of the son tube and the mother tube with various distances, and the problem that an existing clamp cannot be replaced is solved; meanwhile, limiting and protection can be provided for the son tube and the mother tube.
Description
Technical field
The present invention relates to the installation of submarine pipeline and protection device, more particularly to it is a kind of for submarine pipeline install connection and
The separate type primary and secondary pipe clamp of protection.Belong to ocean engineering field.
Background technology
Submarine pipeline is an important component part during deep water hydrocarbon field Development Engineering is built.In order to save submarine pipeline
Operating expenses or simplify submarine pipeline operational procedure, in some production projects, it is therefore possible to use by two small one and large one seas
Bottom pipeline certain forms colligation is got up the method laid together.This small one and large one two pipeline colligations pipeline together claims
For casing.
In the pipe installation process of primary and secondary sea, the connection that sub- pipe and main pipe are completed using clamp is needed.
At present, existing clamp is typically integrated fixed.Because there is adjustment and the feelings for changing in sub- pipe and main pipe spacing
Condition, especially casing two ends need to consciously adjust the spacing of sub- pipe and main pipe to adapt to later stage flange connection needs.In order to
Above-mentioned situation is adapted to, needs the clamp for designing multiple differing heights, different types, so, not only considerably increase design
Workload；It is additionally, since clamp and typically belongs to profiled piece, the mould that the quantity of needs is few but corresponding is a lot, thus
Cause sharply increasing for clamp manufacturing schedule and cost；Meanwhile, a kind of clamp may be only available for the casing connection of a certain height,
Do not possess replaceability, this increased to a certain extent after the damage of offshore construction clamp, it is impossible to the risk of replacement.
The content of the invention
Present invention is primarily targeted at overcoming the disadvantages mentioned above that prior art is present, and provide a kind of separate type casing
Clamp, it can not only be attached sub- pipe and main pipe, and, can be carried out according to the change of the spacing between sub- pipe and main pipe
Adjustment, only just can be suitable for the connection between the son pipe of various spacing and main pipe with a kind of clamp, and solving existing clamp can not
The problem of replacement；Simultaneously, additionally it is possible to provide spacing and protection for sub- pipe and main pipe.
The purpose of the present invention is realized by technical scheme below：
A kind of separate type primary and secondary pipe clamp, it is characterised in that：Including：One be used for the pedestal of connexon pipe and main pipe, one
The individual top protective cap that can be docked with pedestal inner side, outside, a sub- pipe limiting card being embedded in pedestal and general
The binding strap that pedestal links together with top protective cap.
The upper end of the pedestal is provided with the arc-shaped limit groove of the sub- pipe limiting card of a receiving；The lower end of the pedestal is provided with a use
In the arc-shaped limit groove coordinated with submarine pipeline main pipe；
The top protective cap is semicircular structure.
The sub- pipe limiting card is made up of several arc cards for linking together, and the arc card inside after docking is in circle
Shape.
One side of the arc card is provided with, and two adjacent arc inlay cards can be entered the groove being docking together；Another side sets
Having, two adjacent arc inlay cards can be entered the projection being docking together.
Curvature of the curvature on the arc card outer arc surface more than inner arcuate surface.
Beneficial effects of the present invention：Due to adopting above-mentioned technical proposal, it can not only enter sub- pipe and main pipe the present invention
Row connection, and, can be adjusted according to the change of the spacing between sub- pipe and main pipe, only just can be suitable for a kind of clamp many
The connection between the son pipe of spacing and main pipe is planted, the irreplaceable problem of existing clamp is solved；Simultaneously, additionally it is possible to for sub- pipe and
Main pipe provides spacing and protection.

Specific embodiment
As shown in Fig. 1-Fig. 3, the present invention includes：One is used in the pedestal 1, and pedestal 1 of connexon pipe and main pipe
Sub- pipe limiting card 3 that the top protective cap that side, outside can be docked 2, one is embedded in pedestal 1 and by pedestal 1 with
The binding strap 4 that top protective cap 2 is linked together using improving bud grafting.
The upper end of said base 1 is provided with the arc-shaped limit groove of the sub- pipe limiting card 3 of a receiving；The lower end of said base 1 is provided with
One is used for the arc-shaped limit groove with the cooperation of submarine pipeline main pipe.
Above-mentioned top protective cap 2 is semicircular structure.
Above-mentioned sub- pipe limiting card 3 is made up of several arc cards for linking together, and the arc card inside after docking is in
It is circular；
One side of above-mentioned arc card is provided with, and two adjacent arc inlay cards can be entered the groove being docking together；Another side sets
Having, two adjacent arc inlay cards can be entered the projection being docking together.
Curvature of the curvature on above-mentioned arc card outer arc surface more than inner arcuate surface.
When using, pedestal 1 be to be mounted directly to into main pipe top；Sub- pipe limiting card 3 can be according to the relative position of sub- pipe and main pipe
Determination usage quantity is put, and ring is installed on sub- pipe after combining；Then, the spacing further according to sub- pipe and main pipe adjusts sub- pipe limit
Position card 3 and the relative angle of pedestal 1, by adjusting sub- pipe limiting card 3 with the relative angle of pedestal 1 sub- pipe and main pipe are adjusted
Spacing, i.e., using the difference of the curvature between arc card inner surface and outer surface, when rotating different angles, obtain different
Spacing；And complete to dock using jack mode with pedestal 1 by top protective cap 2；Suitable colligation is selected further according to practical situation
Antithetical phrase pipe limiting card 3 is completed with 4 to work with the colligation of top protective cap 2.
The above, is only presently preferred embodiments of the present invention, and any pro forma restriction is not made to the present invention, all
It is above example is made any simple modification, equivalent variations and modification according to the technical spirit of the present invention, still falls within
In the range of technical solution of the present invention.
