Abstract

The invention discloses a flange alignment assembling method and an alignment assembling position degree gauge for implementing the flange alignment assembling method. According to the gauge, the included angle between the connecting line of datum holes in two flanges and the plumb line is measured, so that the positions of the two flanges relative to the plumb line are the same, in other words, under the condition that the plumb line serves as a locating reference, the positions of the datum holes of the two flanges are adjusted, and it is guaranteed that the positions of other bolt holes in the same flange are fixed under the condition that the two datum holes in the same flange are confirmed, so that the positions of the two flanges relative to the plumb line are fixed before the flanges are installed, and in other words, the relative positions of the two flanges are fixed. Therefore, when the flanges are installed on parts, the relative positions of the two flanges do not need to be adjusted; and in the flange alignment assembling method, time and labor are saved for adjustment operation of the two flanges, and the assembling efficiency of the flanges is improved as well.

Description

Flange align assembly method and implement the method align rigging position degree cubing
Technical field
The present invention relates to a kind of flange align assembly method and implement the method align rigging position degree cubing.
Background technique
At present, cover pipe part is used in a large number in the field such as power construction, construction, and the sleeve body two ends of these cover pipe parts are all equipped with flange usually, for ease of construction, usually need the flange at sleeve body two ends to align at assembling stage, even if obtain each bolt penetration hole corresponding align on flange, to ensure that workmen can construct flexibly.In traditional sleeve part assembly technology, first sleeve body is kept flat, by fixed for the flange of sleeve body one end, again sleeve body is erected, the one end making sleeve body be equipped with flange is placed in below, one end of unassembled flange is in top, then flange is contained in advance the upper end of sleeve body, the pendant hung on the flange of upper end is utilized to carry out the flange with lower end, bolt penetration hole on flange on the upper and lower end of sleeve body is alignd mutually, but in actual use, there is following defect in this assembling mode:
1, the position of pendant on upper and lower two flanges relies on the range estimation of assembly crewman to judge completely, the eyesight and the working experience that to the situation that aligns of two flanges be made to depend on assembly crewman completely like this, make aligning precision and can not being guaranteed of flange, the assembly precision margin of error that also result in each cover pipe parts is larger;
2, the size of the cover pipe parts used in power construction is larger, the diameter of this type component general is at more than 1m, length is then at more than 5m, and two flanges be required in the scope within 1mm to positive error, this just makes flange align in process, the minimum rotation adjustment position of upper flange, also can cause the significantly swing of pendant, thus make flange align process to waste time and energy.
Summary of the invention
The object of this invention is to provide the flange that a kind of flange improving component two ends aligns operating efficiency and align assembly method, additionally provide simultaneously a kind of be exclusively used in implement that this flange aligns assembly method align rigging position degree cubing.
In order to realize above object, in the present invention, to align the technological scheme of assembly method as follows for flange:
Flange aligns assembly method, comprises the following steps:
Step one, erected by two flanges to be aligned, and choose a pair respectively as datum hole in each bolt through-hole of two flanges, the relative position of two pairs of datum holes on residing flange is identical;
Step 2, measures the angle between the line in the axle center of two datum holes on same flange and vertical line, and by making the described angle on two flanges identical around central axis rotary flange;
Step 3, will be arranged on the two ends of component via two flanges after step 2 adjustment.
In step one, in two datum holes selected on same flange, one is in directly over flange raised state lower flange central axis.
In datum hole selected on same flange, another is in immediately below flange raised state lower flange central axis.
The technological scheme aligning rigging position degree cubing of the present invention is as follows:
Aligning rigging position degree cubing, comprising the pedestal for being connected across on flange between two datum holes, pedestal is rotatably equipped with for around the pendulum swung with the axis being parallel of residing flange or the rotation axis that overlaps.
Pedestal and/or pendulum are equipped with the measuring piece for detecting relative displacement size between pendulum and pedestal or Angular Dimension when pedestal erects.
Measuring piece is dial gauge, and the table body of dial gauge to be fixed in pendulum and pedestal upper, a gauge outfit top and to be contained in pendulum and pedestal on another.
The corresponding positioning pin hole offered for mutually aliging when pedestal is in vertical position on pendulum and pedestal.
Pendulum comprises the swing arm part that swings and be assemblied in shaft-like or rope form on pedestal and the fixing tup of projecting end thereof.
Pedestal is the telescopic flexible bridge of length.
The end winding support of pedestal has the positioning rod for being installed in datum hole, positioning rod is fixed with for the interdiction piece of block on the aperture, two ends of datum hole, and in interdiction piece, at least one is provided with the orientational cone-shaped surface for coordinating with the inclined-plane, edge in corresponding aperture.
By the angle between the line of datum hole on measurement two flange and vertical line in the present invention, to make two flanges identical relative to the position of vertical line, namely when taking vertical line as positioning datum, position adjustment has been carried out to the datum hole on two flanges, with when by determining two datum hole on same flange, ensure that the position in all the other each holes of each bolt on flange is fixed, thus make before flange is not installed, two flanges are fixing relative to the position of vertical line, also just the relative position of two flanges is fixed, when so again flange being installed on component body, without the need to adjusting the relative position of two flanges again, in the assembly method of therefore this kind of flange, the adjustment operation of two flanges will become time saving and energy saving, also the efficiency of assembling of flange is just made to improve.
