Description
Technical field
The present invention relates to nuclear engineering equipment class field, in particular it relates to high-level waste hold-up vessel sealing welding is mended automatically
Repay device.
Background technology
It is high-level waste hold-up vessel using the device that waste canister is collected processing to high radioactivity solid waste, high
Put and just can be kept in after waste storage container needs sealing welding and be transported outward.It is applied to commonly using certainly of radioactivity place on the market
Workpiece rotary welding gun not flowing mode mainly adopted by dynamic welding machine, because this waste canister weighs 5 tons, should not realize the welding of rotational workpieces
Mode, and using market commonly use welding machine rotate waste canister carry out sealing welding machine difficulty larger, and price is too high.
Content of the invention
The technical problem to be solved be provide a kind of workpiece motionless welding gun rotation welder, simultaneously in order to
Ensure the formedness of welding, it is to avoid artificially close, realize machine automatization and compensate, be i.e. the unartificial gap controlling welding gun and weld seam
Automatically keep constant and realize automatic compensation function.
The present invention the technical scheme is that high-level waste hold-up vessel sealing welding that solves the above problems compensates automatically
Device, including the drive mechanism outside high-level waste hold-up vessel upper surface, including axis and high-level waste hold-up vessel
The parallel level connection joint mechanism in upper surface, including the vertical bindiny mechanism that axis is vertical with high-level waste hold-up vessel upper surface,
Including the axis compensation mechanism parallel with high-level waste hold-up vessel upper surface, compensation mechanism includes sleeve body and position
Slide mass within sleeve body, sleeve body inwall is connected with slide mass by helical spring, and slide mass is away from helical spring
One end is connected with vertical bindiny mechanism, and sleeve body is provided with pulley away from one end of vertical bindiny mechanism, and pulley is placed on height and puts
On waste storage its external diameter face, wherein, drive mechanism, level connection joint mechanism, vertical bindiny mechanism are sequentially connected with, level connection joint
The axis of the axis of mechanism and compensation mechanism is each perpendicular to the axis of vertical bindiny mechanism, and sleeve body outer wall is provided with weldering
Rifle, the soldering opening of welding gun aims at the circumferential weld of high-level waste hold-up vessel；The axis of drive mechanism is held with high-level waste storage
The dead in line of device.
After said structure design, first problem to be solved by this invention is: the rotation of workpiece motionless welding gun, with suitable
5 tons of high-level waste hold-up vessels should be weighed without rotation, and only rotary welding gun can achieve to high-level waste hold-up vessel
Circumference soldering operates, and its principle is: drive mechanism is positioned over outside high-level waste hold-up vessel upper surface, using drive mechanism
Driving level connection joint mechanism, vertical bindiny mechanism successively, after compensation mechanism, revolving force being driven on welding gun so that welding
Rifle is subjected to around the circumference of high-level waste hold-up vessel, and level connection joint mechanism, vertical bindiny mechanism, automatically compensation machine
The combinative structure of structure makes driving force turn to use.
Second Problem to be solved by this invention is: realizes machine automatization compensation, unartificial control welding gun and weld seam
Gap automatically keep constant and realize automatic compensation function.Because inside the high-level waste hold-up vessel of the present invention, dress has radiation
Property material, it is thus impossible to by the way of human weld, need to carry out automatic welding using the device of mechanical automation, simultaneously
Control welding gun that must not be artificial keeps constant it is therefore desirable to arrange the part of automatic compensating action automatically with the gap of weld seam, originally
The part enabling above-mentioned functions in invention is compensation mechanism, because the position of drive mechanism is constant, therefore vertically connects
Mechanism is constant apart from the distance of drive mechanism axis, if directly welding gun is fixed on vertical bindiny mechanism, welding gun distance is driven
The distance of motivation structure axis is constant, and because high-level waste hold-up vessel is not a standard cylinder body, its high-level waste is stored
There is mutation (mutation refers to: the jumping phenomenon of surface irregularity) in the circumferential surface of container, therefore welding gun is apart from high-level waste
Gap between the circumferential surface of hold-up vessel can change with the change of the anglec of rotation, and therefore the depth of weld is also inconsistent,
Such welding quality existing problems.In order to avoid the problems referred to above, the present invention utilizes sleeve body and is located at the cunning within sleeve body
Kinetoplast and helical spring composition automatic compensation structure, wherein slide mass due to being connected with vertical bindiny mechanism, therefore slide mass
Constant apart from the distance of drive mechanism axis, and sleeve body under the pressure of helical spring from trend high-level waste hold-up vessel
Circumferential surface extrudes, and welding gun is then fixed on sleeve body, therefore, because sleeve body remains and high-level waste hold-up vessel
Circumferential surface extruding contact, and welding gun also can be maintained at certain clearance gap with the circumferential surface of high-level waste hold-up vessel
From, said process and effect we term it automatic compensate.The Second Problem of the present invention so can be solved.
The effect of each mechanism above-mentioned is respectively.

Compensation mechanism: compensation mechanism is connected with vertical bindiny mechanism, but can not circumferentially rotate, can only be vertical
Move up and down in bindiny mechanism, compensation mechanism and fixed mechanism or compensation mechanism are connect with high-level waste hold-up vessel
Contact is a walking mechanism with roller, and the walking mechanism with roller is above-mentioned pulley, can hold along by weldering high-level waste storage
Device circumference is mobile.
Generally speaking, technique scheme it is achieved that 1, can automatically compensate fixed mechanism and radioactivity container because of centering
The dislocation of size that error causes it is ensured that welding gun with by the constant distance of weldering container；2nd, reduce personnel's raying dosage level, realize
Automatic-sealed welding function to radioactivity container；3rd, reduces cost, is greatly improved equipment cost performance.
Welding gun is fixed on sleeve body outer wall by welding gun governor motion.
Welding gun governor motion be adjust welding gun soldering angle, welding gun apart from welded piece distance, can be with automatic during welding
Compensation mechanism automatically moves.

Mechanism lower end is provided with roller, makees circumferential movement in fixed mechanism upper surface under the driving of motor.Horizontal auxiliary balance mechanism
Can adjust in level connection joint mechanism, to adapt to various sizes of container welding.
Drive mechanism is motor.
Also include fixed mechanism, fixed mechanism is connected with drive mechanism by connecting plate.
Fixed mechanism: fixed mechanism is the immobilizing foundation of whole device, is also the location base of automatic welding.It can be one
Individual barrel shaped structure or other independent support support bodys, the bung seam of barrel shaped structure is used for positioning, and is placed on hold-up vessel sealing
The side of covering.Capping is towards the upper surface of the face as high-level waste hold-up vessel of barrel shaped structure.
