Background technique
At sea in the petroleum development engineering, usually laying submarine pipeline between the production platform or between production platform and the land, by submarine pipeline oil gas is carried.Therefore, undersea pipe-laying is as an important component part of offshore oil and gas field development ﹠ construction, and exploitation, production and the product of offshore oil and gas field are played a very important role the aspect such as defeated outward.
The development trend of world today's offshore oil is to move towards the deep-sea, along with the progress of offshore and gas development technology, at present, the operating water depth of state-of-the-art production platform has reached 3000m in the world, drilling depth surpasses myriametre, and the laying depth of water of submarine pipeline has also reached about 3000m.This just has higher requirement to undersea pipe-laying.
At present, undersea pipe-laying method the most commonly used is: adopt pipe laying barge to carry out pipelaying work.
The pipelaying work process is as follows:
⑴ after land fabrication factory is prefabricated into the setting segmentation, ship off to submarine pipeline on the pipe laying barge;
With the submarine pipeline segmentation piecemeal assembly welding become preseting length;
⑶ pipeline section slipped into marine from the pipe support rack of pipe laying barge afterbody when pipe laying barge moves forward after welded.
In the process of above-mentioned whole pipelaying work, the length that pipeline section glides must be synchronous with the displacement amount of ship, and simultaneously, pipe laying barge must be in more stable state.
The submarine pipeline segmentation of land fabrication, its length is generally: the 12.2M(single node) or the 24.4M(double-nodal point), in the pipelaying work process, need to be the submarine pipeline segmentation from sending pipeline to be transported on the pipe laying line, then, again on the pipe laying line with submarine pipeline segmentation assembly welding piecemeal.Owing to whole sending automatic deviation rectifying function not being set on the pipeline, so that the submarine pipeline segmentation is in being transported process, malposition often, after being transported on the pipe laying line, need to take a long time by manually it being adjusted, therefore, reduce the efficient of pipelaying work.
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 pipe-conveying device with automatic deviation rectifying function, it is installed in and send between pipeline and the pipe laying line, can ajust cloth to the submarine pipeline that tilts because of various factors on the pipe laying line; Thereby reduced submarine pipeline in the time that the adjustment of pipe laying line aligns, improved manufacturing efficiency.
The objective of the invention is to be realized by following technological scheme:
A kind of pipe-conveying device with automatic deviation rectifying function, it is characterized in that: comprising: inner gimbal, external frame, running motor, limit stoper, wherein, inner gimbal is nested in the inside of external frame, and the inside of external frame is equipped with oil hydraulic cylinder, and the piston rod of oil hydraulic cylinder links to each other with inner gimbal, the cylinder body of oil hydraulic cylinder links to each other with external frame, the bottom of external frame is equipped with several wheels, and the wheel bottom is provided with rail, and rail is fixed on the deck of pipe laying barge; Running motor is fixed on the external frame, and the front end of running motor is equipped with gear, this wheel and rack engagement, and tooth bar is fixing above deck; Limit stoper is to be made of several limit switches, wherein, the upper and lower bit switch is installed on the external frame, and left and right sides limit switch is installed in the two ends, the left and right sides of rail, limit switch links to each other with position transducer in the automatical control system that send pipeline up and down, and position transducer links to each other with solenoid valve.
The top of described inner gimbal is provided with the wearing plate of V font.
Described running motor is oil hydraulic motor.
Beneficial effect of the present invention: the present invention is owing to adopting technique scheme, and it is installed in and send between pipeline and the pipe laying line, can ajust cloth to the submarine pipeline that tilts because of various factors on the pipe laying line; Thereby reduced submarine pipeline in the time that the adjustment of pipe laying line aligns, improved manufacturing efficiency.
