It contacts the outer peripheral surfaces 22a and 31a of the machine body 2 and the accumulator 3. Thus, the pair of support members 4 and 5 are positioned while absorbing the dimensional tolerance and assembly tolerance of the compressor body 2 and the accumulator 3. Since the pair of support members 4 and 5 intersect each other, the compressor side end portions 4a and 5a and the container side end portion 4b of the pair of support members 4 and 5 are pressed by the pressing jig 8. 5b are moved simultaneously and positioned.

  Next, the portions closer to the compressor body 2 than the intersecting portions 6 of the support members 4 and 5 (that is, the compressor-side end portions 4a and 5a) are fixed to the outer peripheral surface 22a of the compressor body 2 by welding. Then, the portion closer to the accumulator 3 than the intersecting portion 6 of each of the support members 4 and 5 (that is, the container side end portions 4 b and 5 b) is fixed to the outer peripheral surface 31 a of the accumulator 3 by welding. Thereby, the accumulator 3 can be supported by the compressor main body 2 in a state where variations in the relative position P between the compressor main body 2 and the accumulator 3 in a plan view are suppressed.

-Features of pressure vessel support structure and pressure vessel support method-
The pressure vessel support structure and pressure vessel support method of the present embodiment have the following characteristics.

(A)
In this pressure vessel support structure and pressure vessel support method, by adjusting the crossing angle α between the pair of support members 4, 5, a portion closer to the compressor body 2 than the crossing portion 6 of each support member 4, 5 ( That is, it is possible to change the position of the compressor side end portions 4a and 5a) and the portion of the accumulator 3 side (that is, the container side end portions 4b and 5b) in plan view with respect to the intersecting portions 6 of the support members 4 and 5. . For this reason, the dimensional tolerance and assembly tolerance of the compressor body 2 and the accumulator 3 can be absorbed by the pair of support members 4 and 5. And unlike the pressure vessel support structure using the conventional spacer, the operation | work which changes the size of a spacer is unnecessary. Thereby, in this pressure vessel support structure and pressure vessel support method, the assembling workability when the accumulator 3 is supported by the compressor body 2 is ensured, and the relative position between the compressor body 2 and the accumulator 3 in plan view is ensured. Variations can be suppressed.

(B)
In this pressure vessel support structure and pressure vessel support method, since the pair of support members 4 and 5, the compressor body 2 and the accumulator 3 are fixed together by welding, what is a pressure vessel support structure using a conventional band? In contrast, the work of changing the length of the band becomes unnecessary. Thereby, in this pressure vessel support structure and pressure vessel support method, assembly workability when the accumulator 3 is supported by the compressor body 2 can be improved.

(C)
In this pressure vessel support structure, a structure in which a pair of support members 4 and 5 intersect each other is realized by a simple structure in which the slits 4c and 5c of the support members 4 and 5 are inserted. Thereby, in this pressure vessel support structure, the dimensional tolerance and assembly tolerance of the compressor body 2 and the accumulator 3 can be absorbed by a simple structure.

  Moreover, since the 1st supporting member 4 and the 2nd supporting member 5 are engaged in the state which cross | intersected in planar view here, the rigidity as a supporting member can be made high. In addition, since the first support member 4 and the second support member 5 are members having the same shape and the same dimensions, the cost of the support member can be reduced.

(D)
In this pressure vessel support method, the pair of support members 4 and 5 are crossed in plan view while the pair of support members 4 and 5 are supported in the vertical direction so that the crossing angle α can be adjusted. The pair of support members 4 and 5 can be positioned by a simple operation of pressing from both sides of the portion 6. Thereby, the dispersion | variation in the relative position P of the compressor main body 2 and the accumulator 3 in planar view can be suppressed, and the assembly workability | operativity at the time of supporting the accumulator 3 on the compressor main body 2 can be improved.

  Further, in this pressure vessel support method, since the relative position P between the compressor body 2 and the accumulator 3 in a plan view is positioned to be a predetermined relative position, the intersection angle α between the pair of support members 4 and 5 By adjusting the dimensional tolerance, the dimensional tolerance and assembly tolerance of the compressor body 2 and the accumulator 3 can be accurately absorbed. Thereby, in this pressure vessel support method, the variation in the relative position P between the compressor body 2 and the accumulator 3 in a plan view can be reliably suppressed.

-Modification 1-
In the pressure vessel support structure according to the above-described embodiment, straight plate-like members are used as the support members 4 and 5 in plan view (see FIGS. 1 to 5). However, you may use the supporting members 4 and 5 of a shape different from said embodiment.

  For example, a portion closer to the compressor main body 2 than the intersecting portion 6 of the support members 4 and 5 (that is, the compressor side end portions 4 a and 5 a) is curved along the outer peripheral surface 22 a of the compressor main body 2. And / or a support member in which a portion of the support member 4 or 5 closer to the accumulator 3 than the intersecting portion 6 (that is, the container side end 4b or 5b) is curved along the outer peripheral surface 31a of the accumulator 3. 4, 5 may be used. Here, in FIG. 6, the portions on the accumulator 3 side (that is, the container side end portions 4 b and 5 b) with respect to the intersecting portions 6 of the support members 4 and 5 are curved along the outer peripheral surface 31 a of the accumulator 3. The Example using the supporting members 4 and 5 is shown in figure.

  As a result, the compressor body 2 or the accumulator 3 and the pair of support members 4 and 5 are firmly fixed, and the accumulator 3 can be supported more stably.

-Modification 2-
In the pressure vessel support structure according to the above-described embodiment and Modification 1, a cross structure in which the support members 4 and 5 are simply inserted into the slits 4c and 5c is used (see FIGS. 1 to 5). However, you may use the cross structure of the support members 4 and 5 different from said embodiment and the modification 1. FIG.

  For example, as shown in FIG. 7, the insertion holes 4d and 5d are formed in the groove bottoms of the slits 4c and 5c of the support members 4 and 5, and the engagement shaft 9 is inserted into the insertion holes 4d and 5d. Alternatively, a structure in which the support members 4 and 5 are inserted into the slits 4c and 5c and intersected may be used.

  Thereby, the insertion state of the slits 4c and 5c of the support members 4 and 5 becomes favorable, and the crossing angle α can be changed smoothly.
