Abstract
The utility model discloses a straight pipe and elbow pipe flange weld positioning device. When the straight pipe flange is welded, the end surface of the flange is perpendicular to the axial cord of the pipe; when a 90 degree flattening elbow flange is welded, the surface of the flange of one end of the elbow is perpendicular to the range line of the surface of the other end of the flange. The utility model can be used for straight pipes with diameters from 32 to 426mm of fourteen kinds of specifications, and the 90 degree flattening elbow flange to weld and position, and does not need gage, sample plate, and hanging wire hammer. Welding and positioning can be realized by string the straight pipe or the elbow, and hanging the flange; the welded and positioned straight pipe or the elbow completely conforms with the request of design specification, and also the utility model is time-saving, labor saving, and does not produce wasters.
Description
Technical field: the utility model relates to a kind of positioner to straight tube ring flange and the flat eye of 90 degree elbow ring flange enforcement welding, can guarantee that the end face that makes ring flange is perpendicular to tube axis when welding straight tube ring flange; When the flat eye of welding 90 degree elbow ring flange, make the extensions of the plane of elbow one head flange dish perpendicular to ring flange plane, other end.
Background technology: at present, all need spending when putting down eye elbow ring flange, by welding straight tube ring flange and 90 for making straight tube ring flange end face perpendicular to tube axis, the ring flange eyelet at two is symmetrical, generally all be with turning the chi model by amount, hang line, the spot welding location with plumb bob; When the flat eye of welding 90 degree elbow ring flange, be to adopt channel-section steel is welded into 90 degree, drawing center line on the groove face, also draw center line on the ring flange, point is welded on the channel-section steel face, puts elbow spot welding location again.After the welding of elbow ring flange was finished, the ring flange elbow of again spot welding being had good positioning was pounded, and carries out comprehensive welding.Use this technology, the channel-section steel die deformation that flat eye dislocation often occurs and use.Thereby traditional ring flange welding procedure efficient is low, and deviation is big, causes waste; As using by force, then changed the trend of setting up of pipe, destroyed the integral layout of pipeline.This shows, make a positioner of guaranteeing to reach designing requirement, increase work efficiency when making straight tube and the welding of elbow ring flange, seem very necessary.This has become welder's universal demand.
Summary of the invention:
For solve current straight tube ring flange and the flat eye of 90 degree elbow ring flange welding positioning process loaded down with trivial details, take a lot of work, drawback such as deviation is big, the utility model adopts following technical proposals: on a straight channel-section steel, load onto the positioner of corresponding two displacements that can slidably reciprocate, riser perpendicular to the platform panel is arranged on the positioner platform of every side, have on the riser and 14 kinds of corresponding eyelets of specification ring flange eyelet; The location eyelet that 14 kinds of specification ring flanges can be installed is also arranged on the plane of one side locating platform.Two corresponding positioner bottoms are provided with a plurality of rollers, use the fastening location of maintenance knob in move left and right to the appropriate location.There is holder to prop up between the locating platform of both sides and falls frame.
Following effect and effect are arranged: can weld and use in straight tube, the flat eye of the 90 degree elbow ring flange spot welding location of 14 kinds of specifications altogether for diameter 32-426mm,, also need not to hang plumb bob after the utility model utilization without measurer, model.Put on straight tube or elbow, hang and lay out ring flange, just can the direct spot welding location.Straight tube that spot welding locatees out or elbow meet the design specification requirement fully, and the time and labour saving does not go out waste product.Holder is propped up and is fallen frame and can make pipe move left and right, oscilaltion.When the jack height did not satisfy welding requirements, the hoisting rack that falls in the frame is propped up in holder can secondary lifting, with the pipe that adapts to all size and the location welding of elbow ring flange.
Description of drawings:
Fig. 1 is the utility model straight tube, the structure chart of elbow ring flange (the flat eye of 90 degree) apparatus for welding and positioning: in the drawings: 1, riser, 2, riser fine setting maintenance strut, 3, the platform panel, 4, platform floor, 5, roller, 6, positioning knob, 7, ring flange maintenance pin, 8, straight tube, 9, the flat eye of 90 degree elbow ring flange pin, 10,90 degree elbows, 11, holder is propped up and is fallen the frame roller, 12, holder is propped up and is fallen the frame positioning screw hole, 13, jack, 14, the trustship pulley, 15, cylinder body, 16, the landing bar, 17, the bolt knob that hoists, 18, ring flange maintenance pin, 19, riser, 20, riser fine setting maintenance strut, 21, the platform panel, 22, roller, 23 platform floors, 24, positioning knob, 25, channel-section steel.
The specific embodiment:
Contrast accompanying drawing 1 specifies the details of the actual welding of the utility model: with the positioner working platform device of two correspondences on a straight channel-section steel 25, on channel-section steel 25, horizontally slip by a plurality of rollers 5,22, locate at once to appropriate location screwed in place knob 6,24.Respectively adorn a vertical riser 1,19 on the positioner platform panel 3,21, riser 1,19 is fixed the ring flange of certain specification by ring flange maintenance pin 7,18, and the perpendicularity that riser 1,19 and platform panel 3,21 are loaded onto behind the pipe is regulated control by riser fine setting maintenance strut 2,19.On the panel 3 of a fixture platform, the flat eye of workpiece 90 degree elbow ring flange is fixed with the flat eye of 90 degree elbow ring flange pin 9.Prop up by holder and to fall frame roller 11, jack 13, cylinder body 15, landing bar 16, can regulate holder support height, allow the holder support arrangement on channel-section steel 25, horizontally slip.After installing pipe or flat eye elbow and measuring the extensions of plane perpendicular to ring flange plane, other end of end face perpendicular to tube axis, elbow one head flange dish of determining ring flange, can implement weld job, end product quality can be guaranteed to adhere to specification.
