Abstract
The utility model relates to a centering centralizer of triangular supporting flanges belonging to an auxiliary tool of the pipeline installation, which mainly solves the problems that the construction of centering flanges and pipelines is complex and the quality is difficultly guaranteed in the welding of the flanges and the pipelines. The centralizer comprises a central hole which is traversed through an end plate (2) on a leading screw (2). a fixed plate (13), a front and a rear fixed rods (12, 9) and a central rod (8) which is orderly hinged with both ends of the rods (12, 9), and a connecting rod (7), wherein a hinged support (10) is arranged on the middle portion of the connecting rod (7), one end of the central rod (8) is hinged on the hinged support (10), and the fixed plate (13) is fixed on the inner side of the end plate (2). The centralizer can guarantee the sealing surface of the flange to be perpendicular to the axial cord of the pipeline and the requirements of the concentricity of the two axial cords during the welding of the pipeline and the flange, guarantees the construction quality, and has simple and convenient operation.
Description
Technical field
The utility model relates to a kind of pipeline assist location instrument, particularly a kind of gusseted flange centering centralizer is installed.
Background technology
In pipelayer's journey work progress, often run into the welding of pipeline and flange.Be the glacing flatness that guarantees that process pipe is installed, when welding, must make pipe centerline keep vertical and coaxial inner conductor with flange sealing surface.At present, horizon rule commonly used or steel set-square are checked the perpendicularity of pipe centerline and flange sealing surface, the shortcoming that exists is: at first owing to be subjected to the restriction of W.N flange boss structure, angle square can not be close to pipeline, gapped between angle square and the tube wall, and increase along with the flange nominal diameter, this gap can be increasing, this moment, way by hand checked that the perpendicularity of pipe centerline and flange sealing surface has become very difficult, more can't check the axiality of pipeline and flange axial line, the quality assurance difficulty is big, and operating process is loaded down with trivial details.
The utility model content
For construction reference, the simplification work progress that guarantees that flange connects, the utility model provides a kind of gusseted flange centering centralizer, the vertical requirement that reaches two axial line concentricitys of flange sealing surface when this centralizer can make pipeline install with flange with the pipeline axial line, guarantee construction quality, simple to operation.
The technical solution of the utility model is: a kind of gusseted flange centering centralizer, comprise that end plate, fixed head, front and back fixed bar that centre bore is through on the leading screw reach and hinged successively intermediate bar, the connecting rod in its two ends, the connecting rod interposition is equipped with hinged-support, and an end of intermediate bar is articulated on the hinged-support; Fixed head is fixed in the end plate inboard.
Uniform three spill hinged-supports on the fixed bar of described front and back; Connecting rod and on hinged-support be three; Intermediate bar is six; The inboard fixedly fixed head of end plate; The centre bore of leading screw and end plate and back fixed bar is for being threaded.
The beneficial effects of the utility model are: because this gusseted flange centering centralizer has adopted leading screw and gusseted structure, front and back fixed bar, intermediate bar and connecting rod are hinged and constitute the gusseted linkage, the power of rotating threaded shaft passes to connecting rod by fixed bar and intermediate bar, make the inwall of connecting rod extrusion pipe, guarantee centralizer, flange, the concentricity of pipeline and the perpendicularity of flange and pipeline, the centering quality is good, and is simple to operation, and there have to be time saving and energy saving.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
By accompanying drawing 1 to shown in the accompanying drawing 5, this gusseted flange centering centralizer, comprise flange 5 and pipeline 6, flange 5 leans against on the inner face of end plate 2 and is fixing by bolt, nut (3,4), end plate 2 is for middle circle and centre bore is arranged, there is the auxilliary plate in the location of symmetry both sides, and the elongated hole 14 that on the auxilliary plate adjustable bolt position is arranged is shown in accompanying drawing 2 and accompanying drawing 3, and the inboard of end plate 2 is fixed head 13 fixedly; Pipeline 6 inwalls that the termination is through at flange 5 endoporus have 3 connecting rods 7 that axially contact with it, and connecting rod 7 is at pipeline 6 inwall radial equipartitions, the interposition of each connecting rod 7 is equipped with hinged-support 10, end by hinged-support 10 and 6 intermediate bars 8 is hinged, the other end of intermediate bar 8 respectively with preceding fixed bar 12 and back fixed bar 9 on the matrix hinged-support 11 at two ends be connected shown in accompanying drawing 4 and accompanying drawing 5, and preceding fixed bar 12 is fixed on the fixed head 13 of end plate 1 inboard, and leading screw 1 passes fixed bar (9,12), the centre bore of fixed head 13 and end plate 2, and with end plate 2 and the back fixed bar 9 centre bore be threaded; 3 connecting rod 7 shape sizes are identical, and 6 intermediate bar 8 shape sizes are identical, and bar (7,8) is uniform form with respect to pipeline 6 and leading screw 1.
In actual the use, earlier flange 5 is passed through bolt and nut (3,4) be fixed on the end plate 2, supporting mechanism with centralizer inserts in the pipeline to be installed then, rotating threaded shaft 1, back fixed bar 9 moves to the direction of end plate 2 on leading screw 1, make intermediate bar 8 produce a extruding force to pipeline 6 inwalls, make the inwall tight connecting of connecting rod 7 with pipeline 6, gusseted mechanism and flange keep concentric with pipeline 65 this moments and the pipeline axial line perpendicular to end face of flange, the centering work of flange 5 is finished, can carry out spot welding afterwards, after treating that flange 5 spot welding are fixing, with leading screw 1 reverse rotation, fixed bar 9 moves to the direction away from end plate 2, the extruding force that 7 pairs of pipelines of connecting rod bar 6 produce disappears, and flange centering centralizer takes out in the pipeline 6 that installs.Because this gusseted flange centering centralizer has adopted leading screw and gusseted structure, front and back fixed bar, intermediate bar and connecting rod are hinged and constitute the gusseted linkage, the power of rotating threaded shaft passes to connecting rod by fixed bar and intermediate bar, make the inwall of connecting rod extrusion pipe, guarantee centralizer, flange, the concentricity of pipeline and the perpendicularity of flange and pipeline, the centering quality is good, and is simple to operation, and there have to be time saving and energy saving.
