Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As viewed in figures 5-8, be the schematic diagram of the utility model case frequency converter cabinet framework embodiment, this skeleton can form case frequency converter rack with side plate and door-plate.Case frequency converter cabinet framework in the present embodiment is the framework be made up of two front columns, 52, two rear columns, 51, four crossbeams 53 and four longerons 54, and front column 52 and all vertical setting of rear column 51.The two ends of crossbeam 53 connect top or the bottom of two front columns 52 respectively, or the two ends of crossbeam 53 connect top or the bottom of two rear columns 51 respectively.One end of longeron 54 connects top, other end connection rear column 51 top of front column 52, or one end of longeron 54 connects bottom, other end connection rear column 51 bottom of front column 52.Certainly, in actual applications, the front column 52 of greater number, rear column 51, crossbeam 53 and longeron 54 can also be adopted, with the user demand of satisfied different occasion.
Above-mentioned front column 52 and rear column 51 are formed by vertical open architecture section bar (namely cross section is not closed), and front column and 52 rear columns 51 include at least six vertical bendings, and the folding face of the both sides of each bending is vertical.Certainly, on section bar, the quantity of bending also can increase, to meet the Structural strength calls of column.
As shown in Fig. 6,8, above-mentioned rear column 51 is made up of 7 bendings and 8 folding faces, and has the first fin 511 and the second fin 512 be made up of four bendings respectively, and wherein the first fin 511 is projected into the outer and top surface being parallel of the main body of longeron 54 in longeron 54; Second fin 512 is then projected into the outer and top surface being parallel of the main body of crossbeam 53 in this crossbeam 53.
There is at an edge of this rear column 51 longitudinal direction folding face 513, another edge of being parallel to longeron 54 there is the transverse direction folding face 514 being parallel to crossbeam 53, and the first fin 511 protrudes from this longitudinal folding face 513, second fin 512 protrudes from this horizontal folding face 514.With existing nine folded sections or sixteen fold section bar cabinet type structure rack similarly, above-mentioned horizontal folding face 514 and longitudinal folding face 513 are equipped with the circular hole for installing cabinet inner beam or cabinet plate and square hole.
As shown in Figure 7,8, front column 52 is made up of 6 bendings and 7 folding faces, and this front column 52 has the 3rd fin 521 be made up of four bendings.3rd fin 521 protrudes from the outer and top surface being parallel of the main body of longeron 54 in longeron 54.
There is at the edge of the close rear column 51 of this front column 52 the rear folding face 522 being parallel to longeron 54, and the 3rd fin 521 protrudes from this rear folding face 522.Above-mentioned rear folding face 522 is rolled over face 513 with the longitudinal direction of the rear column 51 being positioned at the same side and is positioned at same plane.With existing nine folded sections or sixteen fold section bar cabinet type structure rack similarly, above-mentioned rear folding face 522 is provided with circular hole for installing cabinet inner beam or cabinet plate and square hole.
In addition, the edge away from rear column 51 of front column 52 has and is parallel to folding face 523 before longeron 54, and this front folding face 523 is connected with the end face of the 3rd fin 521 via three bendings and two folding faces.Further, above-mentioned front folding face 523 protrudes from outside crossbeam 53.
Because front column 52 and rear column 51 have employed non-closed type section bar, therefore the end of front column 52, rear column 51 directly can connect the end (crossbeam 53 can directly adopt the structure identical with existing beam with longeron 54) being welded and fixed crossbeam 53 and/or longeron 54, and without the need to adopting extra connecting tee.Thus reduce processing, assembling amount, improve efficiency of assembling, improve machining accuracy, realize rack standardization, generalization, modularization.
Certainly, in actual applications, above-mentioned front column 52 and rear column 51 also can adopt identical structure.Especially, above-mentioned front column 52 and rear column 51 all can be bent by cold-reduced sheet and form.
Compared with the cabinet type skeleton of nine folded sections, the front column 52 of above-mentioned case frequency converter cabinet framework and rear column 51, through being repeatedly bent into open architecture, are convenient to follow-up spraying integrality, improve anti-corrosion capability.Compare nine folded section structures, above-mentioned case frequency converter cabinet framework weight saving 15%, have more inner usage space, around cabinet angle all can and cabinet.
Compared with sixteen fold section bar cabinet type structure, above-mentioned case frequency converter cabinet framework has absolute advantage on cost.
The above; be only the utility model preferably embodiment; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range of claim.
