Abstract
The invention discloses a double-end vertical pipe clamp which comprises a pair of guide pipe leg holding clamps and two vertical pipe clamps oppositely arranged on the guide pipe leg holding clamps. The guide pipe leg holding clamps and the vertical pipe clamps are respectively formed by two semi-cylindrical structures oppositely connected together in a buckled mode. A vertical pipe clamp support is installed between the guide pipe leg holding clamps and the vertical pipe clamps. According to the double-end vertical pipe clamp, on the premise that the requirements for production operations on the sea are met, the using number of the guide pipe leg holding clamps is reduced, the requirement for installation space is lowered, and the problem of space interference is solved. In addition, the usage amount of steel is reduced, the construction period is greatly shortened, the building cost is greatly reduced, and economic benefits are improved.
Description
Technical field
The present invention relates to ocean platform, relate in particular to a kind of being suitable for and need on conduit leg of ocean platform, connect two and above double end stem clamp.Belong to Offshore Engineering field.
Background technology
In petroleum development engineering, often to use the support fixed structure such as standpipe and clamp at sea.
As shown in Figure 1, offshore oil exploiting platform is divided into upper and lower two large divisions, and top is upper module 1, and various production and living facilities (not shown) can be installed on it, and bottom is passive pile foundation jacket 2.Jacket 2 mainly comprises: four columniform conduit legs 3 and piling bar 4, standpipe 5 or 5 ' be to connect the production tree of upper brace and the pipeline of benthal oil-gas pipeline, need to use riser clip 6 that standpipe is fixedly connected with jacket in order to resist the various loads such as environmental forces, riser clip is to guarantee the platform important structure that standpipe peace interstation has safety and firmness to connect during one's term of military service.
At present, the connection of riser clip and jacket mainly contains: holding card and two kinds of forms of welding.Wherein, it is that arm two ends are all dismountable tubular clamps that holding card connects, one end card standpipe, and the other end is stuck in conduit leg or lacing wire.The clamp of this form is easy for installation, but requires have sufficient space that tubular clamp is installed in conduit leg or lacing wire, can not have too much other accessory structure space interference.Being welded to connect is that arm one end is detachable tubular clamp, and the other end is welded in conduit leg or lacing wire.It is little that the clamp of this form takies space in conduit leg and lacing wire, and still, at sea especially Underwater Welding operating difficulties expense is higher, is more suitable for the platform of the prefabricated pre-installation in land.
Along with the construction exploitation of offshore oil and gas field, the transformation of the newly-increased standpipe of the platform of being on active service increases, often need to increase many standpipes newly along a conduit leg or lacing wire, so (as shown in Figure 2) each riser clip needs one to embrace leg clamp, as requested, the requirement that space is arranged is larger, need to excise interference structure-anode 12 under water in order meeting the demands, after complete clamp to be installed, then to be welded reset.Therefore, Jobs on the sea amount is very large, constructional difficulties, and expense is higher, in this case, uses conventional riser clip very non-remunerative beyond doubt.
Summary of the invention
Main purpose of the present invention is to overcome the above-mentioned shortcoming that prior art exists, and provide a kind of improved double end stem clamp, it is meeting under the prerequisite of offshore production job requirements, has not only reduced armful usage quantity of leg clamp and the requirement of installing space, has solved space interference problem; And, also reduce the use amount of steel, significantly shorten construction period and construction cost, improve economic benefit.
The object of the invention is to be realized by following technical scheme:
A kind of double end stem clamp, it is characterized in that: comprising: a pair of armful of conduit leg clamp, be relatively arranged on two riser clips of embracing on conduit leg clamp, wherein, embracing conduit leg clamp and riser clip is to be respectively made up of two semicircle cylindrical structures that are relatively fastened and connected together; Embrace and between conduit leg clamp and riser clip, a riser clip is installed and supports.
The end of described two relative semicircle cylindrical structures is provided with several reinforcement gussets, strengthens being provided with the bolt and nut pair semicircle cylindrical structure being linked together for respectively between the space between gusset; And between two reinforcement gussets of a side, rotating shaft, rubber pad and the bolt and nut pair for semicircle cylindrical structure is opened and closed is installed; Make to embrace conduit leg clamp and embrace riser clip by rotating shaft and become a riser clip that can open and close.
Beneficial effect of the present invention: the present invention is owing to adopting above technical scheme, and it is meeting under the prerequisite of offshore production job requirements, has not only reduced armful usage quantity of leg clamp and the requirement of installing space, has solved space interference problem; And, also reduce the use amount of steel, significantly shorten construction period and construction cost, improve economic benefit.

The specific embodiment
As shown in Figure 4, the present invention includes: a pair of armful of conduit leg clamp 9, employing welding manner are arranged on two armfuls of riser clips 7 embracing on conduit leg clamp 9 relatively, wherein, embracing conduit leg clamp 9 and embrace riser clip 7 is to be respectively made up of two semicircle cylindrical structures that are relatively fastened and connected together; Embracing conduit leg clamp 9 and embracing between riser clip 7 adopts welding manner that one riser clip support 8 is installed; The end of two relative semicircle cylindrical structures adopts welding manner that several reinforcement gussets are installed, and strengthens being provided with between the space between gusset bolt and nut for respectively semicircle cylindrical structure being linked together to 10; And between two reinforcement gussets of a side, rotating shaft 11, rubber pad and the bolt and nut pair for semicircle cylindrical structure is opened and closed is installed; Make to embrace conduit leg clamp 9 and embrace riser clip 7 by rotating shaft 11 and become a riser clip that can open and close 6.
When use, two standpipes (5 and 5 ') are distributed in to the both sides of conduit leg 3, are blocked by two to be opened/closed armful of riser clips 7 respectively, embrace riser clip 7 for can open and close clamp structures.After land formation, the clamp opening is blocked respectively to standpipe (5 and 5 ') and conduit leg 3 according to precalculated position at sea by constructor, and the fastening holding card that completes standpipe is connected with bolt and nut.
Layout of the present invention; The space requirement of embracing two clamps on conduit leg 3 becomes as long as interference structure is avoided in the space of a clamp, has solved space interference problem, has avoided cutting welding operation under water, has shortened the offshore construction time.
The above, it is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present invention is done above embodiment, all still belong in the scope of technical solution of the present invention.
