The inner support tool is in an integrated frame structure; a plurality of rib plates are vertically disposed in the integrated frame structure; in the areas divided by the rib plates, the cameras are fixed on the rib plates of the inner support tool through the rack; the upper portion of the inner support tool is provided with notches so that the cameras can monitor outside of the notches of the inner support tool. The tank bottom seam back monitor has the advantages that the tank bottom circular seam welding process can be video-monitored in real time under the condition of not changing the existing welding tool, reliable basis is provided for adjustment of welding parameters, and welding quality is greatly improved.
Description
Technical field
The utility model belongs to container case back welding seam welding control technology field, is specifically related to a kind of tank case back welding seam back monitoring arrangement.
Background technology
For diameter, be at the bottom of 5 meters, structure are the tank case of spherical crown bottom structure, by 8 melon lobes and little top cover, transition rings welding, formed, main weld consists of melon lobe longitudinal joint, top cover circumferential weld, transition rings circumferential weld; Case base ring tailor assembling structure form is the inner inner supporting structure that adopts, the outside key compressing structure that adopts, the process adopting is the unsettled automatic welding process of Variable Polarity TIG, unsettled weldering is leaked backing plate owing to not welding, control requirement to welding conditions is relatively strict, guarantee that stable and consistent is leaked in the weldering of back of weld in welding process.
Therefore,, in girth welding process, situation about need to leak according to back weldering is adjusted welding conditions in real time, with the stable and consistent that guarantees that weldering is leaked.During due to the seam welding of case base ring, directly observe weldering leakage very difficult, this just need to introduce special video system and come the weldering of Real-Time Monitoring weld seam to leak situation.
Summary of the invention
The purpose of this utility model is to provide back monitoring arrangement at the bottom of a kind of tank case, and situation is leaked in the weldering that can observe tank case back welding seam to be welded for welding operator, for realizing 5m diameter tank case base ring, stitches unsettled weldering and provides safeguard.
The technical solution of the utility model is as follows: back monitoring arrangement at the bottom of a kind of tank case, this device comprises inner support frock, camera and stand, wherein, inner support frock is general frame structure, in its frame structure, be arranged vertically several floors, and in the region of being separated by floor, several cameras are fixed on by stand on the floor of inner support frock, on inner support frock top, have breach, make camera can monitor the situation outside inner support frock breach.
Described inner support frock top is the circular arc slab construction matching with inwall at the bottom of tank case to be welded, and have several breach in this circular arc slab construction, inner support frock bottom is the perpendicular slab construction in two side and bottom surface, and top circular arc dull and stereotyped with lower flat plate structure between by flat board, be connected or be connected by ladder flat board.
Described inner support frock is provided with three vertical floors, and inner support frock is divided into 4 spaces.
In 4 spaces in described inner support frock, be provided with 4 cameras.
On described stand, have through hole, by this through hole, the connection line of the control signal input being connected with camera and pilot signal output can be drawn to inner support frock.
Remarkable result of the present utility model is: back monitoring arrangement at the bottom of a kind of tank case described in the utility model, do not changing under the condition of existing welding tooling, realization is to the real-time video monitoring in tank case base ring seam welding process, for the adjustment of welding parameter provides reliable foundation, significantly improved welding quality.
