A kind of welding tractor
The utility model belongs to the welder field, relates in particular to a kind of welding tractor.
Make large-size cylinder body equipment and need extensively to adopt welding procedure; To barrel soldering the time, often adopt manual welding, or use weld holder; This welding manner is inefficiency not only, and the welding quality of product also can not be guaranteed.When cylindrical shell equipment last closed up seam welding, generally all is to adopt the mode of manual welding to weld, but in tank, has a large amount of flue dust during manual welding, can cause to employee's health serious consequence.
Summary of the invention
The purpose of this utility model is the shortcoming that overcomes prior art, and a kind of welding tractor that large-size cylinder body is welded be convenient to is provided.
For solving the problems of the technologies described above, concrete technical scheme of the present utility model is as follows:
A kind of welding tractor is characterized in that: comprise vehicle frame and be arranged on the running wheel of bottom of frame, described vehicle frame inside is provided with power set, and power set drive wheel movement;
Also comprise a column, the bottom of described column is vertically connected at vehicle frame by flange;
Comprise a horizontal gird, be connected on the column by built-up jig that this built-up jig is provided with the column fishbolt;
Crossbeam in column one side is provided with wire reel and electrical control panel, and described wire reel can be around self axis rotation by on bearing pin connection and the described crossbeam;
Crossbeam at described column opposite side is provided with wire feeder and welding gun, and described welding gun is connected with wire feeder;
Described control panel and wire feeder and power set communicate;
Also comprise a guide rail; Described wheel is provided with annular groove, and described guide rail is to the running wheel guide support.
Further, also be provided with welding-torch horizontal guiding mechanism and longitudinal adjusting mechanism between described welding gun and the horizontal gird.
The utility model is simple and reasonable, has basically realized automation, adopts welding tractor to weld the labour intensity that greatly reduces the workman, and the quality of welding is more excellent simultaneously.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Come the utility model is further described below in conjunction with accompanying drawing.
As described in Figure 1, the utility model comprises vehicle frame 1 and is arranged on the running wheel 2 of vehicle frame 1 bottom, also comprise a guide rail 10, described running wheel 2 is provided with annular groove, being convenient to 10 pairs of wheels 2 of guide rail leads and supports, described vehicle frame 1 inside is provided with power set, and power set drive wheel 2 walkings.One column 3 is set above vehicle frame 1 vertically, and post end is connected with vehicle frame 1 top by flange.On column 3, also be provided with a horizontal gird 4, connect by built-up jig 5 between the two and be provided with column fishbolt 6, unclamp column fishbolt 6 and can realize that horizontal gird 4 rotates at horizontal plane.Horizontal gird in column 3 one sides is provided with an electrical control panel 8 and wire reel 7, and described wire reel 7 can be around self axis rotation by on bearing pin connection and the described crossbeam 4.On the horizontal gird 4 of column opposite side, be provided with the wire feeder 9 and the welding gun 10 that link to each other mutually, between welding gun 10 and horizontal gird 4, also be provided with welding-torch horizontal guiding mechanism 12 and longitudinal adjusting mechanism 13, be used for regulating the position of welding gun.The communication that links to each other with driving power device, wire feeder 9 of described electrical control panel 8 is used for controlling the motion of wire feed action and dolly.When the utility model is used for large-size cylinder body welded, when the A of cylindrical shell, B seam welding, utilize the mobility of dolly, allow it move along bead direction, can directly weld the slit.When the interior girth joint of welding inner barrel, dolly is placed interior girth joint bottom, the speed that dolly is set equates with the velocity magnitude that cylindrical shell rotates but opposite direction makes dolly be positioned at all the time the cylindrical shell bottom, so just can realize the welding of internal girth joint; In welding during outer ring weld, only need with welding tractor place outer ring weld directly over and keep static, rotary barrel just can be finished welding.
The utility model is simple and reasonable, has outstanding mobility and higher automaticity, can not only to A, the B seam welding of cylindrical shell, also can weld the last seam that closes up of cylindrical shell simultaneously; Greatly lowered workman's labour intensity.
