Description
Technical field
It the utility model is related to argon filling dress during a kind of a kind of argon-filling device, more particularly to Large Diameter Pipeline high alloy steel pipe welding
Put.
Background technology
In recent years, China's thermal power generation unit is just towards high efficiency, high parameter, the overcritical of large capacity, ultra supercritical hair
For motor prescription to development, 1000MW Main Steam Pipeline of Unit has introduced P92 steel, and P91, P92 belong to new fine grain
Strengthening and Toughening ferritic heat-resistant steel, its high temperature, high-voltage performance are good, but its weldability is poor, when particularly carrying out root layer welding to it,
Prime coat back easily aoxidizes, and generates scoriform thing, substantially reduces the performance of weld seam.Therefore, to the steel pipe of P91, P92 steel
When carrying out root layer welding, back of weld must carry out effective argon-filled protection, just be avoided that root aoxidizes, so as to obtain the weldering of qualification
Seam, ensures the mechanical performance of connector.The prior art, in the construction of such welded steel, for pipe of the caliber within 500 millimeters,
Use soluble paper before welding, such as newspaper, numb paper are at the scope apart from about 500 millimeters of weld bond, by pre-welding pipeline opening
Blocked, make a closed argon filling gas chamber；Before welding, at groove into pipeline argon filling in closed applying argon gas room, generally
Argon filling needs half an hour.And when caliber is more than 500 millimeters, since caliber is big, overpressure is big, is easily made with this method
Breakage occurs into soluble paper or stickup is not tight, causes closed argon filling gas chamber poorly sealed, there is air entrance, the back side produces oxidation
Phenomenon is serious, causes weld bond root protecting effect bad, seriously affects welding quality.Such case generation is more, even
It can cause to reprocess, and reprocess that difficulty is also bigger, and speed is slow, seriously affect the quality and progress of engineering, while this method
Also there is the problem of waste argon gas, time-consuming and laborious.
The content of the invention
The utility model provides a kind of high alloy large-diameter pipe automatic argon filling robot, solves large-diameter steel pipe and carries out root
Applying argon gas operation difficulties greatly and expends the technical problem more than argon gas during layer welding.
A kind of high alloy large-diameter pipe automatic argon filling robot, including aluminum walking dolly, are set on aluminum walking dolly
There is travel driving motor, the wheel of aluminum walking dolly is permanent magnet magnetism wheel, fixes and sets in the front end of aluminum walking dolly
Vertical telescopic arm support is equipped with, vertical telescopic arm is provided with vertical telescopic arm support, is fixed on the top of vertical telescopic arm
Swing arm driving variable-frequency motor is provided with, swing arm driving variable-frequency motor is horizontally disposed, in swing arm driving variable-frequency motor
Output shaft on be fixedly installed vertical telescopic swing arm, applying argon gas box, applying argon gas box are provided with the top of vertical telescopic swing arm
Argon filling tracheae with being set on aluminum walking dolly is connected together.
Aluminum walking dolly is provided in high alloy large-diameter pipe, and applying argon gas box is provided in high alloy large-diameter pipe butt welding
The interior side-lower of seam.
The utility model can meet the welding of in vertical position or horizontal level pipeline, and walking dolly can be in pipeline certainly
By walking and positioning；Vertical telescopic swing arm can freely stretch, and 360 degrees omnidirection rotates freely, and meet the flexible change of reducing requirement
Footpath system, reducing scope, which reaches in the pipeline of 420-1200 millimeters of relatively Large Diameter Pipeline scope, to be used.
