Abstract
The utility model relates to a pipeline welding workstation, which chooses a diesel as motor. The diesel is connected with an intermediate frequency dynamo and a power-frequency dynamo by a gear derailleur and a springy coupling. The gear derailleur outputs two powers. The springy coupling drives separately the intermediate frequency dynamo and the power-frequency dynamo. The intermediate frequency dynamo is double rotors double-stator structure. The two paths of independent power-frequency electricity output by the intermediate frequency dynamo are connected with two welding outputting connector through a control box to supply power to welder part with standalone double welding holders. The power-frequency dynamo outputs single-phase alternating current and three-phase alternating current as power-frequency assisting power through the control box. The welding workstation uses the intermediate frequency dynamo as the welding power and the power-frequency dynamo as assisting power. The welding workstation and the assisting power are independent from each other. The welding is free from other assisting operations. The unique unibody structure of the intermediate frequency dynamo achieves independent power supply of two welding holders, thereby solving the robbing power problem between the two holders.
Description
Technical field
The utility model designs a kind of welding equipment, particularly a kind of pipeline welding work station that is used for.
Background technology
At present, for the welding of the long conveyance conduit of middle heavy caliber, mainly adopt double symmetrical welding, layering continuous productive process.Therefore on welding equipment, twoly will progressively replace the weldering welding equipment singly the weldering welding equipment, be that the two of power will become leading equipment to integrated welding equipment simultaneously with the diesel engine.What now the diesel engine that adopts in the world directly drove is two the arc generator group, main employing be the power frequency generator for electricity generation, take on the stator of same generator mode on its structure around two bond pads windings and one group of electric winding of power frequency power.But rob between two electrode holders that this mode exists electricity and and power frequency power point between interference problem.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes in the above technology, and a kind of pipeline welding work station is provided.
The technical solution of the utility model is to choose diesel engine to do motive power, diesel engine by gear-shift mechanism and yielding coupling respectively with intermediate frequency generator and power frequency generator electric, through two power of output after the gear-shift mechanism speed change, drive intermediate frequency generator and power frequency generator respectively by yielding coupling again.Intermediate frequency generator is the birotor double-stator structure, and electric two of passing through control cabinet and welding machine output of the two independent intermediate frequency of output weld output interface A and B links, and partly power to the welding machine of separate double electrode holder respectively.The output of power frequency generator is single-phase through control cabinet output, three-phase alternating current is as the power frequency accessory power supply.
The intermediate frequency generator of described birotor double-stator structure includes two rotor assemblies, two field frame assemblies, and they are the structure of coaxial one.Two field frame assemblies are installed in the cylindrical shell, support with left end cap and right end cap, and the stator output line is drawn in the middle of cylindrical shell; Described two rotor assemblies are installed on the armature spindle, and the bearings by the armature spindle two ends is among field frame assembly; Carbon brush component, brush handle assembly are installed in the end of armature spindle.The power of diesel engine reaches the intermediate frequency generator armature spindle after the speed changer conversion, two rotor assemblies rotate synchronously, exciting current arrives two rotor coils through carbon brush component, collector ring, thereby produce two fully independently rotating excitation fields, two nail coil cutting magnetic lines and produce independently induced-current of two-way safety incessantly independently are to supply with two electrode holders of welding machine part.
In the cylindrical shell of described intermediate frequency generator centrifugal fan is installed, design has heat dissipation wind channel on the whole generating machine, heat dissipation wind channel is the perforate by the right end cap top, the space at field frame assembly inside and outside circle place, and perforate forms jointly on the through hole at rotor assembly middle part and the left end cap circumference.When armature spindle rotated, under the effect of centrifugal fan, cold wind entered from right end cap, flowed along circle cylindrical and rotor assembly middle part through hole in the field frame assembly, absorbed the heat of rotor, stator, discharged from left end cap, thereby guaranteed that the generator heat radiation is good.
This work station has adopted full-closed structure as a complete machine, and the complete machine that diesel engine, intermediate frequency generator, power frequency generator and other accessories sections are formed is arranged in the shell by integral body, forms full-closed structure.
Welding machine partly adopt separate double the weldering, every handle is provided with manual metal-arc welding, cellulose welding rod down hill welding, three kinds of function shelves of self-protection flux-cored wire semiautomatic welding, wherein self-protection flux-cored wire semiautomatic welding gear can with Lincoln's wire-feed motor and Miller wire-feed motor interface.
The utility model compared with prior art has following advantage:
1, as the source of welding current, the power frequency generator is as accessory power supply with intermediate frequency generator for this welding workstation, and the two is separate, and welding is not subjected to the interference of other auxiliary operations when therefore working.
2, the unique texture of the coaxial one of intermediate frequency generator has been realized the independently-powered of two electrode holders, has fundamentally solved the electric problem of robbing between two electrode holders.
3, the design of the air channel of intermediate frequency generator can guarantee that motor radiating is good.
4, this work station has electric welding and generating two purposes.
