Description

The quick maintenance device of submarine pipeline
Technical field
The present invention relates to a kind of machinery technology, specifically a kind of device for submarine pipeline installation, R and M, the quick maintenance device of submarine pipeline that the leak stoppage pipe clamp being specially adapted to submarine pipeline is installed.
Background technique
The installation of submarine pipeline, R and M are very difficult operations, wherein install the regular operation that pipe clamp is a repairing submarine pipeline.Traditional installation method of pipe clamp is under water, uses crane or crane barge aboard ship, first transfers the leakage position of pipe clamp to submarine pipeline, then by diver by after the upper pipe clamp installation in position of pipe clamp, then use suspension hook to sling, after overall package is good lower pipe clamp, with bolt tightening, complete pipe clamp and install.Need many people repeatedly to descend the installation of water ability during installation, if carry out deepwater work, diver is difficult to operation.Particularly marine vessel has unstability, and crane also can with sallying, pipe clamp location difficulty, and installation difficulty increases, and considerably increases diver's workload and unsafe factor; When carrying out deepwater work in addition, due to flood tide or ebb, diver cannot carry out operation.Therefore, be starved of the device of the pipe clamp mounting tool of the submarine pipeline proposing a kind of new structure and the maintenance operation of submarine pipeline, more convenient and quicker is carried out the installation of pipe clamp safely and is carried out the installation R and M operation of some other submarine pipeline.
Summary of the invention
The object of the invention is to solve the problems of the technologies described above, proposing a kind of submarine pipeline maintenance device, this maintenance device, hydraulic pressure installation is set, the locating support of flexible operation, structure improvement, easy to use, to the repairing leak stopping of submarine pipeline, pipe clamp is installed good especially with other maintenance operation effectivenesses.
The object of the invention is to be achieved through the following technical solutions:
The quick maintenance device of submarine pipeline, it is characterized in that: be provided with cross bracket, this support is fixed together by a vertical beam and a crossbeam intersection and forms, a fixing locating clamp plate is respectively equipped with in the rear and front end of described vertical beam, this clamp is vertical with vertical beam downwards, and the clamp left and right sides is provided with two downward card pipe teeth, is equipped with a fixing oil hydraulic cylinder in the inner side of each clamp, the piston rod of this oil hydraulic cylinder stretches downwards, and piston-rod lower end is provided with a pressure pipe card; On the crossbeam of described support, the left and right sides is respectively equipped with a snap arm that can move left and right on crossbeam, and the lower end of each snap arm is equipped with an inside land, the convenient pipe clamp connecting submarine pipeline leak stopping sealing of this land; The inboard of snap arm is connected with the piston rod power of an oil hydraulic cylinder respectively.
The present invention improves further and the additional project of enforcement is:
The vertical beam of described support is provided with hanger.
The card pipe tooth of the clamp both sides that described vertical beam rear and front end is arranged is split type card pipe tooth, is divided into two denticles, and their upper ends intersection is connected on an axle actively, and lower end is provided with inside crotch.This card pipe tooth matches with described pressure pipe card, can adjust the position of the submarine pipeline of disconnection up and down.
The crossbeam two ends of described support are respectively equipped with the air bag of a fast aeration.
The oil hydraulic cylinder at described vertical beam two ends and the oil hydraulic cylinder of the crossbeam left and right sides are provided with synchronizer.
The quick maintenance device of submarine pipeline of the present invention is when installing pipe clamp, and diver or robot only need button press, under the effect of synchronizer, the locating clamp plate of vertical beam rear and front end is synchronized with the movement, and support is correctly positioned at leakage place of submarine pipeline.Now, the snap arm that can move left and right carries the pipe clamp of stifled dew sealing, in water, keep balance, and synchronizing moving in opposite directions in the horizontal direction, guarantee the stability of pipe clamp, under the promotion of oil hydraulic cylinder, correct for pipe clamp is arranged on the leakage mouth of submarine pipeline.Then tighten pipe clamp bolt, removal bracket, regain support, whole plugging operations completes very soon.Described hanger is convenient to the lifting of frame, and described air bag can protect the left-right balance of support well.Available machines used people replaces diver to complete the installation of unmanned deep water.The unstability of ship, on the location of support also without any impact, because locating clamp plate can play good positioning action.And connect without the need to hinge between the pipe clamp of left and right, pipe clamp is split into two halves, and is directly installed in moveable snap arm.And, a pack support can supporting various specifications submarine pipeline leak stopping sealing pipe clamp.The present invention also can be used to the lifting carrying out submarine pipeline of harmless pipe surface and various upkeep operation.The present invention have structure improvement, diverse in function, easy to use, save time and cost, flexibly and fast, safe and reliable plurality of advantages.
Accompanying drawing explanation
Fig. 1 is perspective view of the present invention;
Fig. 2 is the structural representation of the split type card pipe tooth of clamp of the present invention.
The profile of product of the present invention is not by the restriction of this figure, and only profile change also belongs to protection scope of the present invention.
