Abstract

The utility model discloses a welding tractor with guiding wheels. The welding tractor with the guiding wheels comprises a walking tractor frame, connecting rods, the guiding wheels and an electric welding machine, wherein the number of the connecting rods is two, the two connecting rods are arranged on the tractor head and the tractor tail of the walking tractor frame respectively in parallel, the number of the guiding wheels is two, the two guiding wheels are connected with the connecting rods respectively, and the electric welding machine is arranged on a welding machine seat of the walking tractor frame. Due to the fact that the connecting rods and the guiding wheels are arranged on the walking tractor frame, by means of resultant action formed by forward driving force of the walking tractor frame and normal force of the guiding wheels born from a component curve-surface, the walking tractor frame walks a curve track by means of the curve surface component, automatic welding which is conducted on a curve welding joint formed in the curve-surface component is finished, and the application problem that the automatic welding tractor is applied to the curve welding joint can be solved. Therefore, the welding tractor with the guiding wheels has the advantages of being high in welding speed, and high in forming quality of the welding joint.

Present stage, in the structure of large-scale important building, steel construction has become the main body of fabric structure, and the shape of structure is tending towards curveization, variation, no longer is simple horizontal vertically flat.In the construction operation in " door in east " the sightseeing Room, project top, because its top structure is made up of arc component entirely, the weld seam of its member mostly is camber line, and the quality requirement of butt welded seam is very high, because a large amount of existence of curved welding seam, the reality that automatic weldering dolly can only be used for straight bead has been initiated challenge, the automatic weldering dolly of prior art is used for the straight bead welding more, or the welding of camber line weld seam under given conditions, the running orbit of dolly is by track control, before the welding, must lay track by the track of weld seam.The problem that exists is, lays the box component of the track slightly more complicated of track or weld seam for inconvenience, and the application of welding dolly automatically just has been subjected to restriction, can only adopt CO 2Gas shielded arc welding carries out manual welding, and not only labour intensity is big, and even weld is poor, and speed of welding is slow, and moulding is undesirable.
The utility model content
The purpose of this utility model is a kind of welding tractor that is provided with directive wheel that provides at the deficiencies in the prior art.The utility model is provided with connecting rod and directive wheel on traveling vehicle frame, the force action that the normal reaction in the member curved surface that utilizes driving force that traveling vehicle frame moves ahead and directive wheel to be subjected to forms, make traveling vehicle frame rely on curved surface member to walk out curvilinear path, thereby finish the curved welding seam on the curved surface member is implemented welding automatically, solved the application difficult problem of automatic weldering dolly on curved welding seam, it is fast to have speed of welding, the advantage that the appearance of weld quality is high.
The concrete technical scheme that realizes the utility model purpose is:
A kind of welding tractor that is provided with directive wheel, its characteristics comprise traveling vehicle frame, connecting rod, directive wheel and electric welding machine, the headstock of described traveling vehicle frame and the tailstock are provided with the connection pole socket, the top is provided with the welding machine seat, and an end of connecting rod is provided with axle bed, and directive wheel is provided with regulating shaft; Described connecting rod is two, and on the parallel respectively connection pole socket of being located at the traveling vehicle frame headstock and the tailstock, directive wheel is two, is connected with the axle bed of connecting rod through regulating shaft respectively, and is positioned at a side of traveling vehicle frame, and electric welding machine is located on the welding machine seat of traveling vehicle frame; Be provided with bearing in the described directive wheel, be inlaid with insulation sleeve between bearing and the directive wheel.
The utility model is provided with connecting rod and directive wheel on traveling vehicle frame, the force action that the normal reaction in the member curved surface that utilizes driving force that traveling vehicle frame moves ahead and directive wheel to be subjected to forms, make traveling vehicle frame rely on curved surface member to walk out curvilinear path, thereby finish the curved welding seam on the curved surface member is implemented welding automatically, solved the application difficult problem of automatic weldering dolly on curved welding seam, it is fast to have speed of welding, the advantage that the appearance of weld quality is high.
