Abstract
The utility model relates to a submerged-arc welding tractor for minor diameter pressure vessel barrels. The welding tractor mainly comprises a tractor and a machine head, wherein a welding control case and a welding wire reel are arranged on the tractor; and the machine head comprises a wire guiding mechanism, a current contact nozzle and a welding flux funnel. The innovations provided by the utility model lie in that the end part of the tractor is connected with the machine head via a horizontal connecting pipe extending forwards; a plurality of wire guiding racks are arranged on the connecting pipe; welding wires on the welding wire reel extend into the wire guiding mechanism of the machine head through the wire guiding racks; and a guide wheel insulated with the machine head is further mounted at the bottom of the machine head. The welding tractor has the advantage that the machine head is connected with the tractor via the connecting pipe and a guide wheel insulated with the machine head is further arranged at the bottom of the machine head, so that when the welding tractor is used, the tractor is positioned outside the barrel, the machine head extends into the barrel via the connecting pipe, and the guide wheels move forwards along a welding joint on the inner side of the barrel to enable the machine head to move along a slope on the inner side of the machine head and smoothly perform submerged-arc welding, thereby further reducing labor intensity of staffs, improving working environment, and enhancing working efficiency and welding quality.
Description
Technical field
The utility model relates to a kind of welding tractor, particularly a kind of minor diameter pressure container cylinder submerged-arc welding welding tractor.
Background technology
In the production technology of pressure vessel, need carry out the welding of drum shaft, because the structural limitations of barrel space and submerged-arc welding welding tractor all can not adopt submerged-arc welding for the axial weld seam of the pressure container cylinder below the diameter 900mm to weld seam.The general dual mode that adopts: carry out the groove manual argon arc welding bottoming of the cylindrical shell outside, the stick electrode weldering is filled and capping, or the submerged-arc welding capping; Perhaps adopt inboard groove, arc welding bottoming by hand, cover welding, submerged-arc welding capping behind the back chipping of the outside, stainless steel product will be considered backside gas protection problem in this way.There is shortcoming in it: labor strength is big, if use the welding of inboard groove, work situation is poor, inefficiency, and also product quality is subjected to the influence of employee skill factor big, and flaw detection qualification rate is low.
The utility model content
The technical problems to be solved in the utility model provides a kind of welding tractor that carries out submerged-arc welding in the minor diameter pressure container cylinder that stretches into.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of minor diameter pressure container cylinder submerged-arc welding welding tractor, comprise dolly, be located at welding control cabinet and wire reel on the dolly, and the head of forming by thread guide mechanism, ignition tip, flux hopper, its innovative point is: the tube connector that stretch out forward by a level end of described dolly is connected with head, tube connector is provided with several silk guide frame, welding wire on the wire reel stretches in the thread guide mechanism of head by silk guide frame, and be equipped with in head bottom one with the directive wheel of head insulation.
Advantage of the present utility model is: head is connected with dolly by tube connector, and at the directive wheel of bottom setting with its insulation, when welding like this, dolly is positioned at outside the cylindrical shell, head section stretches in the cylindrical shell by tube connector, and directive wheel moves ahead along the inboard weld groove of cylindrical shell, makes head along inboard groove walking carrying out smoothly submerged-arc welding, improve working strength of workers and operating environment, improved operating efficiency and welding quality.
Description of drawings
Accompanying drawing is the utility model minor diameter pressure container cylinder submerged-arc welding welding tractor structural representation.
The specific embodiment
As shown in drawings, dolly 1, welding control cabinet 2, wire reel 3, thread guide mechanism 4, ignition tip 5, flux hopper 6, tube connector 7, silk guide frame 8, directive wheel 9.
Above-mentioned dolly 1 is provided with welding control cabinet 2 and wire reel 3, is wound with welding wire on the wire reel 3.Be provided with the head of forming by thread guide mechanism 4, ignition tip 5, flux hopper 6 in the dead ahead of dolly 1.
The tube connector 7 that stretch out forward by level the end of dolly 1 is connected with head.Tube connector 7 is provided with several silk guide frame 8, and the top of silk guide frame 8 is a seal wire ring, and the welding wire on the wire reel 3 passes the thread guide mechanism 4 that each seal wire ring enters head, finally enters in the ignition tip 5.
The bottom of head is provided with an insulating support, and directive wheel 9 is installed on the support, the groove profiling of the profile of this directive wheel 9 and pressure vessel.
During use, dolly 1 places outside the pressure container cylinder, head stretches in the cylindrical shell by tube connector 7, the directive wheel 9 of head bottom drops in the groove, during dolly 1 reach, directive wheel 9 moves ahead along groove, makes solder flux in thread guide mechanism 4, ignition tip 5 and the flux hopper 6 on the head cooperate and carries out inboard submerged-arc welding, after inboard submerged-arc welding is finished, carrying out outside back chipping and submerged-arc welding.
Claims (1)
1. minor diameter pressure container cylinder submerged-arc welding welding tractor, comprise dolly, be located at welding control cabinet and wire reel on the dolly, and the head of forming by thread guide mechanism, ignition tip, flux hopper, it is characterized in that: the tube connector that stretch out forward by a level end of described dolly is connected with head, tube connector is provided with several silk guide frame, and the welding wire on the wire reel stretches in the thread guide mechanism of head by silk guide frame, and be equipped with in head bottom one with the directive wheel of head insulation.
