Description

For the back filled argon protection device of large diameter steel pipe welding
Technical field
The utility model relates to welding equipment technology, particularly relates to a kind of technology of the back filled argon protection device for large diameter steel pipe welding.
Background technology
In welding production process, often there are some larger-diameter steel pipes or cylinder when welding, need the welding procedure adopting back filled argon protection.
Current back filled argon protected mode is all carry out argon filling to workpiece lumen; and by workpiece two ends ferrule, it is more that this back filled argon protected mode expends argon gas, and thus welding cost is also higher; and need the closed work piece two ends mouth of pipe, operate also very inconvenient.
Utility model content
For the defect existed in above-mentioned prior art, technical problem to be solved in the utility model is to provide one can reduce welding cost, facilitates the back filled argon protection device for large diameter steel pipe welding of welding operation.
In order to solve the problems of the technologies described above, a kind of back filled argon protection device for large diameter steel pipe welding provided by the utility model, is characterized in that: comprise logical argon pipe fitting, travel(l)ing rest, described travel(l)ing rest comprises base, column, crossbeam, hound;
Described column is fixed on base, crossbeam is horizontally placed on column, and coordinate with column activity, one termination column of hound, another termination crossbeam, and hound coordinates with column, crossbeam are all movable, crossbeam being equipped with the locking sleeve for locking hound, column being equipped with the locking sleeve for locking crossbeam and hound;
The right-hand member of described crossbeam is fixed with counterweight platform, and described logical argon pipe fitting is fixed on the left end of crossbeam by a standing screw;
Described logical argon pipe fitting is the circular arc pipe fitting towards crossbeam direction arc convex dorsad, logical argon pipe fitting offers air inlet and gas outlet, gas outlet is wherein arranged on crossbeam side dorsad, and this gas outlet is an arc line shaped opening consistent with the radian of logical argon pipe fitting, logical argon pipe fitting is equipped with the adjustment sheet for regulating this gas outlet aperture.
The back filled argon protection device for large diameter steel pipe welding that the utility model provides; the logical argon pipe fitting of utilization coordinates with travel(l)ing rest, argon gas directly can be passed to back of weld, and can according to the gas outlet aperture of the logical argon pipe fitting of weld seam length adjustment; thus realize the local argon charging protection of back of weld; can reduce argon gas use amount, thus save welding cost, and structure is simple; change flexibly; controllability is comparatively strong, and operation is also very convenient, is applicable to the steel-pipe welding of plurality of specifications.

Detailed description of the invention
Illustrate below in conjunction with accompanying drawing and be described in further detail embodiment of the present utility model, but the present embodiment is not limited to the utility model, every employing analog structure of the present utility model and similar change thereof, all should list protection domain of the present utility model in.
As Figure 1-Figure 4, a kind of back filled argon protection device for large diameter steel pipe welding that the utility model embodiment provides, it is characterized in that: comprise logical argon pipe fitting 2, travel(l)ing rest 1, described travel(l)ing rest 1 comprises base 16, column 11, crossbeam 14, hound 15;
Described column 11 is fixed on base 16, crossbeam 14 is horizontally placed on column 11, and coordinate with column 11 activity, one termination column 11 of hound 15, another termination crossbeam 14, and hound 15 coordinates with column 11, crossbeam 14 are all movable, crossbeam 14 being equipped with the locking sleeve 17 for locking hound 15, column 11 being equipped with the locking sleeve 12 for locking crossbeam 14 and hound 15;
The right-hand member of described crossbeam 14 is fixed with counterweight platform 13, and described logical argon pipe fitting 2 is fixed on the left end of crossbeam 14 by a standing screw 3;
Described logical argon pipe fitting 2 is the circular arc pipe fittings towards crossbeam direction arc convex dorsad, logical argon pipe fitting 2 offers air inlet 21 and gas outlet 22, gas outlet 22 is wherein arranged on crossbeam side dorsad, and this gas outlet 22 is arc line shaped openings consistent with the radian of logical argon pipe fitting 2, logical argon pipe fitting 2 is equipped with the adjustment sheet 23 for regulating this gas outlet 22 aperture.
The utility model embodiment is applicable to the back filled argon protection of large diameter steel pipe welding, and its using method is as follows:
Unscrew the locking sleeve 17 on crossbeam 14, and the locking sleeve 12 on column 11, again according to the groove position to be welded of target pipe fitting, regulate height and the depth of crossbeam 14, make the logical argon pipe fitting 2 on crossbeam 14 can extend the back side of groove to be welded, and then each locking sleeve is tightened one by one, make crossbeam 14, hound 15 all locks, and gas outlet 22 aperture of logical argon pipe fitting 2 is regulated by adjustment sheet 23, and on counterweight platform 13, load balancing weight to ensure the balance of crossbeam 14, the air inlet 21 of logical argon pipe fitting 2 is received argon gas source, then logical argon pipe fitting 2 is stretched into target pipe fitting to gas outlet 22 and aim at the groove back side to be welded, argon gas can pass into logical argon pipe fitting 2, again by leading to the back side of the direct outgoing in arc line shaped gas outlet 22 on argon pipe fitting 2 to groove to be welded, thus realize the argon shield of back of weld.
