Abstract
The utility model discloses a kind of sacrificial anode underwater welding equipment based on friction stub weldering, mainly for replacing and the maintenance of the sacrificial anode of the submarine pipeline in ocean engineering and underwater structure.Sacrificial anode Underwater Welding process based on friction stub weldering can be fulfiled assignment by diver or diving robot (ROV).Friction welding (FW) belongs to solid diffusivity, and its welding process affects relatively little by environmental pressure.In addition, comparatively dark in the depth of water, when common diving method cannot arrive, adopt ROV operation can hundreds of rice on the depth of water of km weld.This equipment availability advantage of lower cost, simple to operate, the second best in quality welding point can be obtained.
Description
Technical field
The utility model relates to a kind of underwater welding method, particularly relates to a kind of sacrificial anode underwater welding method based on friction stub weldering and equipment.
Background technology
Along with the development of China's Offshore Oil Industry, the service life of some submarine pipelines and underwater structure is longer, the sacrificial anode to it is installed is needed to change or install, owing to pipeline or works cannot be moved on the bank or weld under anhydrous condition, and along with the increase of China's underwater structure depth of water, there is certain difficulty in common underwater welding method, therefore this patent proposes a kind of sacrificial anode underwater welding method based on friction stub weldering and equipment, mainly for replacing and the maintenance of the sacrificial anode of the submarine pipeline in Offshore Oil Industry and underwater structure.This equipment can by diver's submerged operation, also can by diving robot (ROV) carrying operation.Friction welding (FW) belongs to solid diffusivity, and quality of weld joint affects less relative to the welding point of arc welding method by water environment and environmental pressure.In addition, comparatively dark in the depth of water, when common diving method cannot arrive, adopt ROV operation can weld in the depth of water of hundreds of rice to a few km.The method structure is simple, easy to use, dependable performance, can realize installation and the replacing of sacrificial anode under water, has practical and market application foreground preferably.
Summary of the invention
According to background technology, the purpose of this utility model is to provide a kind of sacrificial anode underwater welding equipment based on friction stub weldering, this equipment can carry out underwater operation by diver or ROV, changes the sacrificial anode of underwater structure or submarine pipeline or installs.
To achieve these goals, the utility model adopts following technical scheme:
A kind of sacrificial anode underwater welding equipment based on friction stub weldering, primarily of positioning and locking magnet (1), frame (2), underwater hydraulic heat inserts module (3), welding main shaft (4), anode assemblies retaining mechanism (5) and anode assemblies detent mechanism (6) composition, wherein: sacrificial anode assembly (7) is placed on welding equipment by anode assemblies retaining mechanism (5) and anode assemblies detent mechanism (6), (2) arrange hanger to frame, positioning and locking magnet (1) inserts module (3) connecting fluid pressure power pipeline by underwater hydraulic heat, weld job is carried out by welding main shaft (4), anode assemblies retaining mechanism (5) is fixing or discharge sacrificial anode assembly (7).
Owing to have employed technique scheme, the utility model tool has the following advantages and effect:
(1) this equipment is using hydraulic pressure as power, adopts the combined type friction welding main tapping with movable sealing, can be operated carry out operation completely under water by diver or ROV;
(2) friction stub welding technology is under water adopted to carry out the welding of sacrificial anode, the quality of welding point is less by Underwater Pressure ambient influnence, and without the need to processing pipeline anticorrosion coating, weight coating etc. before welding, and postwelding is also relatively little to its damage, and the welding point of good quality can be obtained;
(3) utilize magnet adsorption in operation process on workpiece to be welded, the quick separating of equipment and workpiece after having welded, can be realized, convenient to operation.
