The Simple underwater flange is installed facility
Technical field
The present invention relates to a kind of instrument that less important work is installed for submarine pipeline, specifically refer to a kind of Simple underwater flange installation facility.
Background technique
At present, in the operation early stage in marine oil gas field, pipelaying work is vital one operation.The method that generally adopts in prior art is: the prefabricated of sea pipe pipe nipple completed on land, then prefabricated sea pipe pipe nipple is contained on pipe laying barge, when arriving the appointment marine site, pipe laying barge begins the laying operation of straight length, straight length is to be made of welded connection by sea pipe pipe nipple, after the straight length laying is completed, to carry out the installation of expansion bends (between submarine pipeline and platform standpipe) and jumper pipe (between underwater well head and subsea manifold sled), Connecting format herein is that flange connects.The following shallow water submarine pipeline of depth of water 500m is by diver's direct control or the underwater sealing cabin to implement to connect as working space mostly.
The shortcoming of this kind method is: the diver not only needs to complete the fastening of bolt, also must dependence manually will aim at for the flange that connects, due to the complexity of underwater environment, the diver completes simultaneously these two work and not only expends muscle power, and the joint efficiency of flange is very low.
Above-mentioned discussion content purpose is to introduce to the reader All aspects of of technology that may be relevant to the All aspects of of the present invention that below will be described and/or advocate, believe that this discussion content helps to provide background information for the reader, to be conducive to understanding better All aspects of of the present invention, therefore, should be appreciated that it is to read these discussions with this angle, rather than admit prior art.

Embodiment
In order to make those skilled in the art understand better technological scheme of the present invention, the present invention is described in further detail below in conjunction with the drawings and specific embodiments, need to prove, in the situation that do not conflict, the application's embodiment and the feature in embodiment can make up mutually.
Core of the present invention is to provide a kind of Simple underwater flange that facility are installed, and to promote operating efficiency, the muscle power that reduces the diver expends.
As shown in Figure 1, Simple underwater flange of the present invention is installed facility, comprises left hydraulic cylinder supporting frame 1, right oil hydraulic cylinder supporting frame 2, oil hydraulic cylinder 3, flange slide rail 4.Described left hydraulic cylinder supporting frame 1, right oil hydraulic cylinder supporting frame 2 all can be formed by the carbon steel Plate Welding, and the stroke of described oil hydraulic cylinder 3 mainly allows alignment error to determine by the maximum of flange.The tailpiece of the piston rod of oil hydraulic cylinder 3 is fixed on left hydraulic cylinder supporting frame 1, and the cylinder barrel end is fixed on right oil hydraulic cylinder supporting frame 2.Concrete, be provided with the left draw-in groove 12 that can snap in for the tailpiece of the piston rod of described oil hydraulic cylinder 3 on described left hydraulic cylinder supporting frame 1, be provided with the right draw-in groove 22 that can snap in for the cylinder barrel end of described oil hydraulic cylinder 3 on described right oil hydraulic cylinder supporting frame 2, mode by clamping can be fixedly connected with oil hydraulic cylinder 3 respectively easily with left hydraulic cylinder supporting frame 1, right oil hydraulic cylinder supporting frame 2, also for convenience detach.The one side that described left hydraulic cylinder supporting frame 1 is relative with right oil hydraulic cylinder supporting frame 2 is respectively arranged with corresponding left plug-in mounting pin 11 and right plug-in mounting pin 21, and left plug-in mounting pin 11 and right plug-in mounting pin 21 are used for being inserted into the flange hole of flange, so that the flange hole of two flanges is aimed at.Described left plug-in mounting pin 11 and right plug-in mounting pin 21 are two, and two left plug-in mounting pins 11 and two right plug-in mounting pins 21 can make the flange hole of two flanges more easily aim at.Described flange slide rail 4 is flute profile, and flange slide rail 4 can be channel-section steel, perhaps forms flute profile by the carbon steel Plate Welding, and when two flanges to be connected were placed on flange slide rail 4, two trough rims of flange slide rail 4 can make two flanges to the heart.One end of described flange slide rail 4 is provided with riser 41, riser 41 is provided with plug-in mounting pin 42 towards the one side of flange slide rail 4, described plug-in mounting pin 42 is two, and plug-in mounting pin 42 is used for being inserted into the wherein flange hole of a slice flange, prevents that flange breaks away from from flange slide rail 4.
Below in conjunction with Fig. 2, use step of the present invention is described, step is as follows:
1) these facility are placed on operation ship and arrive with ship the installation marine site of extra large pipe;
2) this left hydraulic cylinder supporting frame is arranged on the flange of one section of expansion bends or jumper pipe, left plug-in mounting pin is inserted in the flange hole of this flange;
3) transfer expansion bends or jumper pipe to appointed area under water by operation ship;
4) by the diver, right oil hydraulic cylinder supporting frame is installed to for the other a slice flange that connects, right plug-in mounting pin is inserted in the flange hole of this flange;
5) two flanges are in together on the flange slide rail, two trough rims of flange slide rail can make two flanges to the heart, oil hydraulic cylinder is connected with left hydraulic cylinder supporting frame, right oil hydraulic cylinder supporting frame, utilize oil hydraulic cylinder that two flanges are drawn over to one's side, when drawing over to one's side, left plug-in mounting pin and right plug-in mounting pin can make the flange hole of two flanges aim at;
6) diver can first not have the flange hole that the plug-in mounting pin stops to carry out bolton to facility this moment;
7) at last facility are taken off, complete the fastening of residue bolt, thereby complete the installation of a pair of flange.
The present invention carries out artificial installation exercise with respect to the dependence diver of routine, can greatly shorten the activity duration, take a pair of flange as example, conventional method needs the time, and utilize this facility, can save time of 1/2, not only promote operating efficiency, and diver's muscle power expends and obtained good alleviation.
Set forth a lot of details so that fully understand the present invention in top description, still, the present invention can also adopt other to be different from other modes described here and implement, and therefore, can not be interpreted as limiting the scope of the invention.
In a word; although the present invention has exemplified above-mentioned preferred implementation, should illustrate, although those skilled in the art can carry out various variations and remodeling; unless such variation and remodeling have departed from scope of the present invention, otherwise all should be included in protection scope of the present invention.
