Description

Pipeline butt adjustment positioning pipe clamp frock

Technical field

It the utility model is related to a kind of positioning tool of two pipelines butt welding, Welded Pipe in more particularly to a kind of thermal power plant The positioning pipe clamp frock in road.

Background technology

Four big pipeline of thermal power plant is main steam line, reheating hot arc jet chimney, reheating cold section of jet chimney, high pressure Feedwater piping and highpressure steam conduit tube road etc., four big pipelines are high temperature, pressure piping, have that latus rectum is big, wall thickness is thick, weight is big Feature, and power plant's operating condition is complicated, so the required precision to field pipes butt welding is high.In work progress, pipe The mismatch degree of road combination counterpart positioning directly affects welding quality.Because work on the spot environment is limited, larger positioning tool without Method is implemented at the scene, the low and ineffective problem of butt welded pipeline positioning precision be present.

The content of the invention

The utility model provides a kind of pipeline butt welding positioning pipe clamp frock, and it is right in the installation process of thermal power plant to solve The low technical problem of welded tube road positioning precision.

A kind of pipeline butt welding positions pipe clamp frock, including right butt welded pipeline, left butt welded pipeline, first half pipe clamp anchor ear and later half Pipe clamp anchor ear, snapping ear before anchor ear is provided with the both ends of first half pipe clamp anchor ear, is respectively provided with the both ends of later half pipe clamp anchor ear There is snapping ear after anchor ear, first half pipe clamp anchor ear and later half pipe clamp anchor ear are the left ends for snapping onto right butt welded pipeline, before anchor ear Worn after snapping ear and anchor ear between snapping ear and be connected to pipe clamp anchor ear fixing bolt, it is fixed in the left end side of first half pipe clamp anchor ear First half pipe clamp anchor ear cantilever is provided with, nut before pipeline butt positions is fixedly welded with the left end of first half pipe clamp anchor ear cantilever, Screw before pipeline butt positions is bolted with nut before pipeline butt positioning, first half pipe clamp anchor ear cantilever is rolled to outside pipeline Tiltedly set, later half pipe clamp anchor ear cantilever is fixedly installed in the left end side of later half pipe clamp anchor ear, in later half pipe clamp anchor ear The left end of cantilever is fixedly welded with pipeline butt positioning rear nut, and being bolted with pipeline butt in pipeline butt positions rear nut determines Screw behind position, later half pipe clamp anchor ear cantilever are obliquely installed to pipeline outside, nut and pipeline butt before pipeline butt positioning Positioning rear nut is provided on same positioning circumference, and the center of circle of the setting circle is the central axis with left butt welded pipeline Overlap.

Two first half pipe clamp anchor ear cantilevers are fixedly installed in the left end side of first half pipe clamp anchor ear, are embraced in later half pipe clamp Two later half pipe clamp anchor ear cantilevers are fixedly installed in the left end side of hoop, the spacing of two adjacent pipe clamp anchor ear cantilevers is 90 degree Radian.

The effect of the utility model counterpart specialized Perkins joint is during pipeline butt, and for mismatch, control pipeline is radially Direction, small range movement, fine setting are carried out, reduces pipeline mismatch amount to greatest extent, shortens the counterpart time, improve construction effect Rate, ensure erecting and welding quality.
