Description
Technical field
The present invention relates to nuclear engineering equipment class field, particularly, relate to high-level waste hold-up vessel seal welding autocompensation installation.
Background technology
the device adopting waste canister to carry out collecting process to high radioactivity solid waste is high-level waste hold-up vessel, and high-level waste hold-up vessel just can carry out after needing seal welding keeping in and transport outward.Workpiece rotary welding gun not flowing mode mainly adopted by the conventional automatic welder(welding machine) being applicable to radioactivity place on the market, because this waste canister weighs 5 tons, should not realize the welding manner of rotational workpieces, and adopt market to commonly use welding machine to rotate waste canister to carry out sealing the difficulty of welding machine comparatively large, and price is too high.
Summary of the invention
Technical problem to be solved by this invention is to provide the welder that the motionless welding gun of a kind of workpiece rotates, simultaneously in order to ensure the formedness of welding, avoid artificially close, realize machine automatization and compensate, namely the gap of unartificial control welding gun and weld seam automatically remains unchanged and realizes automatic compensation function.
The present invention's adopted technical scheme that solves the problem is: high-level waste hold-up vessel seal welding autocompensation installation, comprise the driving mechanism be positioned at outside high-level waste hold-up vessel upper surface, comprise the level connection joint mechanism that axis is parallel with high-level waste hold-up vessel upper surface, comprise the vertical bindiny mechanism that axis is vertical with high-level waste hold-up vessel upper surface, comprise the compensation mechanism that axis is parallel with high-level waste hold-up vessel upper surface, compensation mechanism comprises sleeve body and is positioned at the slide mass of sleeve body inside, sleeve body inwall is connected with slide mass by helical spring, slide mass is connected with vertical bindiny mechanism away from helical spring one end, sleeve body is provided with pulley away from one end of vertical bindiny mechanism, pulley is placed in high-level waste hold-up vessel outer diameter face, wherein, driving mechanism, level connection joint mechanism, vertical bindiny mechanism connects in turn, the axis of level connection joint mechanism and the axis of compensation mechanism are all perpendicular to the axis of vertical bindiny mechanism, sleeve body outer wall is provided with welding gun, the soldering opening of welding gun aims at the circumferential weld of high-level waste hold-up vessel, the axis of driving mechanism and the dead in line of high-level waste hold-up vessel.
After said structure design, first problem to be solved by this invention is: the motionless welding gun of workpiece rotates, to adapt to weigh, 5 tons of high-level waste hold-up vessels need not rotate, and only rotary welding gun can realize operating the circumference soldering of high-level waste hold-up vessel, its principle is: be positioned over by driving mechanism outside high-level waste hold-up vessel upper surface, driving mechanism is utilized to drive level connection joint mechanism successively, vertical bindiny mechanism, after compensation mechanism, revolving force is driven on welding gun, welding gun is made to carry out welding operation around the circumference of high-level waste hold-up vessel, and level connection joint mechanism, vertical bindiny mechanism, the combining structure of compensation mechanism makes driving force turn to use.
Second Problem to be solved by this invention is: realize machine automatization and compensate, the gap of unartificial control welding gun and weld seam automatically remains unchanged and realizes automatic compensation function.Because high-level waste hold-up vessel inside of the present invention dress has radioactivity material, therefore, the mode of human weld can not be adopted, need to adopt the device of mechanical automation to carry out automatic welding, the gap of control welding gun that simultaneously must not be artificial and weld seam remains unchanged automatically, therefore the parts that auto-compensation effect is set are needed, the parts that can realize above-mentioned functions in the present invention are compensation mechanism, due to the invariant position of driving mechanism, therefore the distance of vertical bindiny mechanism distance driving mechanism axis is constant, if directly welding gun is fixed on vertical bindiny mechanism, then the distance of welding gun distance driving mechanism axis is constant, because high-level waste hold-up vessel is not a standard round staving, there is sudden change (sudden change refers to: the jumping phenomenon of surface irregularity) in the circumferential surface of its high-level waste hold-up vessel, gap between the circumferential surface of therefore welding gun distance high-level waste hold-up vessel can change along with the change of the anglec of rotation, 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 positioned at the slide mass of sleeve body inside, and helical spring composition automatic compensation structure, wherein slide mass is owing to being connected with vertical bindiny mechanism, therefore the distance of slide mass distance driving mechanism axis is constant, and sleeve body extrudes from the circumferential surface of trend high-level waste hold-up vessel under helical spring pressure, welding gun is then fixed on sleeve body, therefore, contact because sleeve body remains to extrude with the circumferential surface of high-level waste hold-up vessel, and welding gun also can remain on certain clearance distance with the circumferential surface of high-level waste hold-up vessel, said process and effect we be referred to as auto-compensation.So can solve Second Problem of the present invention.
