Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a flange storage jig, and more particularly to a jig for storing a flange using a hole of the flange.
[0002]
[Prior art]
In chemical factories, pipes are renewed on a daily basis due to pipe corrosion and deterioration. Therefore, in each manufacturing site, an appropriate number of necessary parts such as piping materials, flanges and joints is often secured. In particular, members such as flanges are classified and arranged according to the working pressure, welding method, etc., but the arrangement method is simply piled up by type, or tied with a bolt or hole in the closing flange or a string or wire in the insertion hole in the welding flange. It is that.
[0003]
[Problems to be solved by the invention]
However, if the flanges are simply stacked, the upper flange may collapse, and if the holes are bundled with a string or the like, the string will be removed each time the flange is bundled or the flange is removed. After that, the string had to be tied again, and the work was complicated.
[0004]
Further, in any case, when flanges having different diameters are stored together, it is necessary to select and remove the necessary flange when taking out, and the sorting operation is complicated. .
[0005]
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a flange storage jig that can be stored and stored by type, can be easily stored and taken out, and can accommodate different flanges. .
[0006]
[Means for Solving the Problems]
The flange storage jig according to the present invention includes one strut for fitting one of the holes in the flange, the other strut for fitting the other hole of the flange, and a plate for standing the one strut. The one strut and the other strut are arranged side by side, and the pitch between the struts is variable.
[0007]
In the flange storage jig, the flange is stored by inserting one of the plurality of holes of the flange into one of the columns and inserting the other hole into the other column. At this time, since the pitch between the columns can be changed as appropriate, various flanges can be handled. When the flange is stored, it is only necessary to pass the hole of the flange through the support, and the take-out can be lifted from the support as it is. In addition, the flanges that are inserted and housed in these columns have the same distance between holes, that is, the same type of flanges are housed.
[0009]
In the storage jig, the plate is used as a first plate, a notch is formed in the base of one column of the plate, the other column is erected on the second plate, and the second plate A slit is formed at one end of the plate, the slit is fitted into the notch, and the second plate is overlaid on the upper surface of the first plate, and the two plates are engaged with each other. . In this case, the notch can be formed in two chamfers.
[0010]
In another aspect of the storage jig, a long hole is formed in the first plate, a protrusion is formed on the back surface of the second plate, and the protrusion is formed in the long hole of the first plate. By inserting the second plate, the second plate is positioned with respect to the first plate.
[0013]
The length of the column is such that it can be easily carried and moved even when the flanges are stacked and stored. Although it depends on the diameter of the flange, a length that can accommodate about 10 flanges is usually preferable.
[0014]
In addition, since the flange is housed through two struts and is stable with the weight of the flange, the size of the plate does not need to be large enough to provide a function as a pedestal and usually has a width of about 5 to 15 cm. It is sufficient if it has a sufficient area and weight so that it does not fall over when the flange is not stored.
[0015]
If the sizes of the flanges are not so different, there is a risk that they will be mistakenly removed when taken out from the storage location. Therefore, it is preferable to distinguish the flange storage jigs by different colors.
[0016]
The material of the flange storage jig, especially the material of the column, may be usually made of metal, but when storing a glass-lined (GL) closed flange, if the handling is wrong, the GL surface is attached to the end of the column of the jig. May cause problems such as scratching or peeling off the GL surface, so if it is made of metal, it is more preferable to use resin coating or resin or wood. .
[0017]
