Abstract
The utility model relates to a flange centering device, including cylindricality nut (2), with cylindricality nut (2) matched with accommodate the lead screw (1), crank arm (4) with cylindricality nut (2) rigid connection's L type, locate the L type and crank arm support (5) on (4) galianconism, shop bolt (3) of rigid fastening on support (5), wherein the plane of support (5) is parallel with accommodate the lead screw (1) axis, and the axis of shop bolt (3) is perpendicular with the plane of support (5). The quantity of fixed pin (3) be two. The beneficial effect of the utility model: special use under the condition of nonparallel, disalignment, decentraction in a big way in when the maintenance repair to equipment pipe line method orchid, can guarantee the accurate centering of flange, realize rapid Assembly, practice thrift the manpower, save time, improve production efficiency, simple structure, small, simple operation, easily adjust, restricted by space and operating personnel, convenient to popularize and use.
Description
Technical field
The utility model belongs to Flange joint technical field, can be applicable to the flange centering aligning alignment device of two panels malalignment in Chemical Manufacture maintenance, is specifically related to realize adjusting flange fast, to reach the object of convenient maintenance.
Background technology
Flange be between tube and tube or between pipe end or equipment import and export between interconnective bead shape parts, flange being provided with the eyelet for linking, in use combining with through the set bolt of eyelet and pad, nut, making two flange couplings.In petrochemical industry, valve is one of modal equipment, newly-built pipeline valve is installed, replacing a kind of common work especially of old pipeline failure valve, Flange joint is pipeline enclosure, valve and pipeline enclosure, seal between valve and valve and link the most general form, uses very extensive in petrochemical industry.In production system maintenance process, during in order to reach isolation or cut off material, flange must be dismantled, because pipeline is from many reasons such as gravity (suppressing strength), will inevitably cause disalignment after demounting flange, bolt hole misplaces, thus waste time and energy when causing again equipped, a large amount of labours can be sacrificed like this, cause the waste of mass energy, have impact on the raising of productivity effect.Flange center's line malalignment aligning method common is at present: when the multiplex manpower crowbar of the underwater flange that caliber is less carries out the method that corrects, this method waste muscle power, inefficiency; When the pipeline peace rotary valve door that caliber is larger, the equipment such as crane and guide chain can only be used to correct.The method that prior art corrects concentricity not only wastes time and energy, and there is unsafe factor, particularly when adopting crane operation, operating personnel are careless slightly, very easily cause pipeline to damage or personal injury, and existing method can only realize the vertical centering of flange, and by environment, instrument size, orientation etc. circumscribed affect larger, narrow and small for locus or around flange, there is barrier condition under, use traditional method will be difficult to even cannot fulfil assignment.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, propose that a kind of structure is simple, cost of manufacture is cheap, easy and simple to handle, can Fast Installation be realized, time saving and energy saving L-type flange centering device.
The utility model comprises cylindricality nut, the adjustment screw mandrel matched with cylindricality nut, crank arm with the rigidly connected L-type of cylindricality nut, be located at the bearing that L-type is cranked arm on galianconism, be rigidly secured to the shop bolt on bearing, wherein bearing plane with regulate screw axis line parallel, the axis of shop bolt and the plane orthogonal of bearing, can make like this to fit tightly between bearing and flange, facilitate turn to regulate screw mandrel, more save manpower.
Further, the quantity of described fixing pin is two, and it is fixing more firm to make.
Further, described cylindricality nut, L-type are cranked arm, between each parts of bearing for welding or monoblock cast or solid forging form.
The beneficial effects of the utility model:
1) crank arm with the rigidly connected L-type of cylindricality nut, be located at the bearing that L-type is cranked arm on galianconism, be rigidly secured to the shop bolt on bearing, wherein bearing plane with regulate screw axis line parallel, the axis of shop bolt and the plane orthogonal of bearing, regulate screw mandrel through in cylindricality nut, can this device be fixed on flange by fixing pin, adjustment screw mandrel in the nut of turn cylindricality again makes flange shift position, finally complete the whole process of centering, therefore simple operation, time saving and energy saving, especially not parallel in a big way when maintenance repair for equipment installation flange, disalignment, use under the condition of decentraction, the accurate centering of flange can be ensured, realize quick assembling, save manpower, save time, improve production efficiency,
2) this apparatus structure is simple, volume is little, simple operation, be easy to adjustment, limit by space and operating personnel hardly during use, be convenient to promote the use of.
Accompanying drawing explanation
Figure is a kind of structural representation of flange centering device.
In figure: regulate screw mandrel 1, cylindricality nut 2, fixing pin 3, L-type crank arm 4, bearing 5.
Detailed description of the invention
Embodiment 1.
Below with reference to accompanying drawing, the utility model is described in further detail.
The utility model by regulating screw mandrel 1, cylindricality nut 2, fixing pin 3, L-type to crank arm 4, bearing 5 forms, concrete structure comprises: cylindricality nut 2, the adjustment screw mandrel 1 matched with cylindricality nut 2,4 are cranked arm with the rigidly connected L-type of cylindricality nut 2, be located at the bearing 5 that L-type is cranked arm on 4 galianconism, be rigidly secured to the shop bolt 3 on bearing 5, wherein bearing 5 plane with regulate screw mandrel 1 axis being parallel, the axis of shop bolt 3 and the plane orthogonal of bearing 5.The quantity of described fixing pin 3 is two.Described cylindricality nut, L-type are cranked arm, between each parts of bearing for welding or monoblock cast or solid forging form.
Using method: when the flange needing centering two bobbin degree different, can fixing pin 3 be placed in the bolt hole of chimb flange, fixing pin 3 is made to be close to the arc surface of another flange face, therefore whole device can be fixed, now cylindricality nut 2 is positioned at the top of another flange, the adjustment screw mandrel 1 in cylindricality nut 2 tightened by available active spanner, the flange jacking of chimb can be gone, reach the object of centering when regulating screw mandrel 1 to move.
Embodiment 2.
The utility model by regulating screw mandrel 1, cylindricality nut 2, fixing pin 3, L-type to crank arm 4, bearing 5 forms, concrete structure is with described in embodiment 1, the plane of described bearing 5 is almost parallel with adjustment screw mandrel 1 axis, and the axis of shop bolt 3 is substantially vertical with the plane of bearing 5.
Using method is with described in embodiment 1.
