Abstract
The utility model discloses a circular plate clamping device used for strake weld repair and belongs to the field of fixing equipment for welding repair. The circular plate clamping device used for the strake weld repair comprises a rotation rod, a clamping plate, a clamping column, a hydraulic device and a vertical column. The rotation rod is of a long rod shape. The middle of the rotation is connected with the vertical column. Two ends of the rotation rod are respectively connected with the clamping column and the hydraulic device. The clamping plate is located at the bottom of the clamping column. The bottom end of the vertical column is connected with an absorbing disc. The vertical column is connected with the rotation rod through a hinge. The rotation rod can rotate around the hinge. According to the circular plate clamping device used for the strake weld repair, a circular plate can be closely attached on an invar film strake instead of being fixed on a flanging position of the strake. The circular plate is prevented from damaging the flanging of the strake and can dissipate heat quickly with the help of the clamping plate. The circular plate clamping device used for the strake weld repair has the advantages of being convenient to fix high in efficiency and free of damage.
Description
Technical field
Field of fixation devices when the utility model relates to repair by welding, specifically, relate to and be used for the specific purpose tool that invar film D type is repaired in the LNG ship cargo containment system, more particularly, strake repair by welding plectane hold down gag when relating to a kind of LNG carrier cargo containment system construction.
Background technology
LNG carrier (being also referred to as the LNG ship) play a part aspect the transportation of liquefied petroleum gas increasing, China has begun independently to build the LNG ship now, can the LNG ship is called as builds the ship that difficulty is the highest, gold content is maximum in the inercant ships, build the shipbuilding level height that the LNG ship is often representing a country.Maximum difficult point is the freight house in the ship in the LNG ship building course, it is to be used on the freight house that cost when the LNG ship is built has half, because the transportation of the freight house of LNG ship is liquefied natural gas, need to bear-163 ° low temperature, so the main material of the freight house of LNG ship is to adopt the invar film of 0.5-1.5mm thickness to be welded, the most frequently used is the invar film (being also referred to as the invar steel) of 0.7mm.The invar steel contains 36% nickel, and this is a kind of very material of " enervated ", touches water or oil under the normal temperature, and 8 h will get rusty with interior, and since invar steel plate thickness 0.7 mm only in case get rusty, all will scrap for whole.Before dispatching from the factory, general invar steel all covers layer of plastic film protected; every volume is all used plastic bag sealing; be contained in the wooden case; LNG ship job site must be equipped with the air-conditioning with dehumidification function; except the fresh air that offers constructor 25%, to guarantee that also whole cabin inner drying degree remains on more than 60%.Even under such environment, touch unintentionally oil or water, the invar steel also can get rusty in 24 h, so the workpeople must wear rubber gloves when constructing.For NO.96 type LNG cargo containment system, when spot defect was repaired on carrying out invar film strake, the production unit GTT company General Requirements of invar film used a diameter to cover repairing as the plectane of 70mm.The material of plectane, specification are identical with film, use 0.7mm or the thick invar sheet material of 1.0mm to make.With former film strake welding the time, plectane need to be pressed on the invar film strake closely, the edge that exposes simultaneously 5mm welds for manual TIG.Compact heap will have good heat sinking function simultaneously.。
China Patent No. 201020627476.5, open day on 08 03rd, 2011, the patent document that a name is called left-and right-handed screw type circulate plate pressing tool for strake repair is disclosed, this utility model discloses a kind of left-and right-handed screw type circulate plate pressing tool for strake repair (should be plectane, this application file has been write as the garden plate), comprise and laterally be fixed on the metal cross bar that compresses the some top, the metal cross bar lower cylindrical face semi arch short tube that reclined, the lower support of semi arch short tube have a vertical right-handed thread double-screw bolt that arranges; The lower end of right-handed thread double-screw bolt is connected with right-handed screw cap; Be connected with the left hand thread double-screw bolt in the bottom screw of right-handed screw cap; The lower end of left hand thread double-screw bolt connects a horizontally disposed discoid pressure head; Described pressure head is pressed on the described compression point.The principle that this utility model utilizes forward-reverse spiral to extend and to shorten carries out pressing when NO.96 type goods maintenance system invar film D type is repaired repairing garden plate.This utility model can be reliably be pressed on the garden of repairing plate on any point of invar strake, also can compress use at all upper end face, bottom surface, facades simultaneously, has that cost is low, easy to use, a flexible operation, characteristics that efficiency of construction is high.But there is very large problem in this utility model, himself fixedly be that the flange that depends on strake is clamped in fixing, if cause like this Area comparison of invar film strake to be repaired large, the flange of strake is away from the location comparison of repairing, this utility model is difficult to play a role so, and this utility model also may to the flange injury of strake, affect the performance of strake in fixing.
Summary of the invention
The problem that solves
Press when repairing for existing LNG carrier NO.96 type goods maintenance system invar film D type and repair the problem that plectane relatively is stranded, the utility model provides a kind of strake repair by welding plectane hold down gag, can be fixed plectane in all cases.
Technical scheme
For addressing the above problem, the technical solution adopted in the utility model is as follows.
A kind of strake repair by welding plectane hold down gag comprises dwang, pressure strip and hold-down column, also comprises hydraulic means and column, and described dwang is elongated rod shape, and the centre of dwang is connected with column, and two ends are connected with respectively hold-down column and hydraulic means; Described pressure strip is positioned at the bottom of hold-down column; The bottom of described column is connected with sucker; Described column and dwang are connected through the hinge.Dwang can be around hinge through.
Further, the area of described pressure strip bottom surface be the hold-down column cross section area 3-5 doubly.
Further, described sucker is rubber suction cups.
