Description

  Embodiments described herein relate generally to a jig and a diagnostic imaging apparatus.

  In recent years, in an image diagnostic apparatus such as an X-ray CT (Computed Tomography) apparatus, the size of a gantry having a rotating part including a radiation source and a detector for tomography and a fixed part that supports the rotating part has been reduced. It is advanced and transportability is improved. However, when the platform is transported to a predetermined position such as an examination room, the rotating part and the fixed part may be transported separately depending on the size of the equipment (for example, an elevator, a door, etc.) in the middle of the transportation. .

  Here, when the rotating part and the fixed part are separated and transported, the rotating part is a donut-shaped circular shape, so it is not possible to perform work such as rotating when placing on the elevator or passing through the door Few. However, the fixed part is longer in the horizontal direction than the vertical direction that supports the rotating part. Therefore, when it is put on the elevator or passed through the door, it is rotated 90 degrees. May be performed. However, the fixed part has a weight of about 300 to 400 [Kg], and it has not been easy to perform an operation of rotating the fixed part by 90 degrees.

  As shown in FIG. 5, the receiving portion 33 is provided at the outer end portion of the support device 40 provided at both ends in the lateral direction on the bottom plate surface 31. Although hidden by the member 32, a receiving portion 33 is provided on the outer side of the support device 40 on the back side of the drawing as in the front side of the drawing. When the fixing portion 1 is transported to the receiving portion 33, the lower end portion of the side plate 55 (see FIG. 7) in the jig 50 is attached. The receiving portion 33 is fastened to the floor surface with bolts after the fixing portion 1 is transported to the floor surface of the examination room and the jig 50 is removed.

  As shown in FIGS. 3 and 6, the receiving part 34 is provided between the support devices 40 provided at both ends in the lateral direction on the bottom plate surface 31. A lower end portion of a support member 61 (see FIG. 7) in the jig 50 is attached to the receiving portion 34.

  Next, details of a jig to be attached when carrying the fixed part 1 after separating the fixed part 1 and the rotating part 2 will be described. FIG. 7 is a perspective view showing the structure of the jig 50 according to the embodiment. FIG. 8 is a perspective view showing a structure in which a jig 50 is attached to the fixing portion 1 according to the embodiment.

  As shown in FIGS. 7 and 8, the jig 50 includes support members 51 and 61 that are attached to the fixing unit 1 and support the support device 40 and the bottom plate 30 of the fixing unit 1 when the fixing unit 1 is transported. . The support member 61 has a support plate 71 as a force receiving portion for receiving a force for lifting the fixing portion 1 at a position corresponding to the center of gravity G when the jig 50 is attached to the fixing portion 1. A joint plate 63 is provided.

  Specifically, at both ends in the lateral direction of the support member 51, bonding plates 52 are provided for attachment to receiving portions 42 provided at the upper end portion 41 of the support device 40. The joining plate 52 is provided with a hole at a position corresponding to the receiving portion 42, and an attachment bolt 53 is inserted into the hole to be attached to the receiving portion 42. As a result, the upper end portions 41 of the two support devices 40 in the fixed portion 1 are supported at both ends of the support member 51 of the jig 50.

  In addition, a side plate 55 is provided on the joining plate 52 illustrated on the near side by mounting bolts 54. The lower end portion in the vertical direction of the side plate 55 is attached to the receiving portion 33 by an attaching bolt, like the upper end portion. As shown in FIG. 8, the side plate 55 may be two plates that sandwich the support device 40 in the ZZ direction. And the outer wall surface in the side plate 55 has advanced by the width | variety d to the edge part side of the baseplate 30 in the horizontal direction from the outer wall surface of the support instrument 40. FIG.

  As shown in FIG. 7, two support members 61 extending in parallel with each other in the vertical direction (downward) are provided at a predetermined interval across the center of the support member 51 at the intermediate portion of the support member 51. ing. As shown in FIG. 8, holes are provided at positions corresponding to the receiving portions 34 at the lower ends of the two supporting members 61, and mounting bolts 62 are inserted into these holes so that the supporting members 61 are attached to the receiving portions 34. It is done. Thereby, the bottom plate 30 in the fixed portion 1 is supported by the lower end portion of the support member 61 of the jig 50.

  As shown in FIG. 7, between the two support members 61, the support plate 71 is provided via the joining plate 63 so that the position in the vertical direction and the horizontal direction can be adjusted. Specifically, both end portions of the support plate 71 extending in the lateral direction are connected to the support member 61 so as to be sandwiched between the two joining plates 63 in the YY direction. A plurality of holes 64 are provided vertically and horizontally at predetermined intervals on the plate surface of the joining plate 63.

  Accordingly, by connecting the support member 61 and the support plate 71 through the screw 65 to the desired hole 64, the position in the vertical direction and the horizontal direction can be adjusted. As shown in FIG. It is possible to match the position of the provided insertion portion 72 with the center of gravity G. In addition, the space | interval of the hole 64 provided in the joining board 63 may be previously designed according to the model number of the fixing | fixed part 1. FIG. In this case, by connecting the support member 61 and the support plate 71 through the screw 65 to the hole 64 provided in accordance with the model number of the fixed part 1, the position of the insertion part 72 is adjusted to the center of gravity G corresponding to the model number. It is possible.

  As shown in FIG. 7, the insertion portion 72 is a hole or the like provided in the support plate 71 for inserting a cylindrical pipe 73 that is a bar. After attaching the jig 50 to the fixed part 1, the user inserts the cylindrical pipe 73 through the insertion part 72. Then, the user applies a force for lifting the fixing portion 1 from both ends of the cylindrical pipe 73. This force (force) is transmitted from the cylindrical pipe 73 to the insertion portion 72 and is applied to the jig 50, whereby the fixing portion 1 is lifted. At this time, since the position of the insertion portion 72 is adjusted to the center of gravity G, the insertion portion 72 can be lifted while the fixing portion 1 is kept substantially horizontal. Further, when the lifting operation described above is unnecessary, the dimension in the ZZ direction can be reduced by removing the cylindrical pipe 73.

  FIG. 9 is a conceptual diagram exemplifying a case where it is hung from the bag 200 and lifted. FIG. 10 is a conceptual diagram illustrating the case of lifting with the lifting device 300. Specifically, as shown in FIG. 9, both ends of the cylindrical pipe 73 may be hung by the hanging device 201 provided on the rod 200 to lift the fixing portion 1. Moreover, as shown in FIG. 10, you may lift the fixing | fixed part 1 by pushing up the both end sides of the cylindrical pipe 73 with the two raising / lowering tools 300. As shown in FIG. At this time, as shown in FIG. 7, the hanging device 201 and the mounting device 74 for the lifting device 300 may be attached to both ends of the cylindrical pipe 73 after the cylindrical pipe 73 is inserted and attached to the insertion portion 72.

  In the state where the fixing portion 1 is lifted as shown in FIGS. 9 and 10, when the fixing portion 1 is raised from the horizontal direction to the vertical direction (rotation of 90 degrees around the axis about the YY direction) Can be made smaller. For example, since it can be sufficiently rotated by human power, the fixing portion 1 can be easily raised.

  FIG. 11 is a conceptual diagram illustrating the rotation of the fixing unit 1 to which the jig 50 is attached. As shown in FIG. 11, the rotation of the fixing part 1 as illustrated in the upper to middle to lower figures can be easily performed by, for example, human power. In addition, since the jig 50 supports the upper end portions 41 of the two support devices 40, the jig 50 can be prevented from being distorted in the upright state as illustrated in the lower diagram of FIG. .

  Further, when the side plate 55 is placed in the upright state as illustrated in the lower diagram of FIG. 11, the fixing portion 1 is rotated while the roller 80 is rolled over the roller 80. Can be moved. Specifically, since the outer wall surface of the side plate 55 has advanced by a width d from the outer wall surface of the support device 40, the fixing portion 1 is not damaged even if the outer wall surface of the support device 40 is contacted by the roller 80. Can be moved.

  Further, the inner diameter of the insertion portion 72 may be substantially the same as the outer diameter of the cylindrical pipe 73, and a configuration in which lubricating oil or the like is filled between the inner surface of the insertion portion 72 and the outer surface of the cylindrical pipe 73, a bearing, or the like. The configuration may be arranged. That is, the insertion part 72 may be configured to insert the cylindrical pipe 73 so as to be rotatable about an axis (YY direction) through which the cylindrical pipe 73 is inserted. In this case, the user can rotate the fixing unit 1 in a state where the cylindrical pipe 73 is fixed to the hanging device 201 or the lifting device 300. In addition, in this embodiment, although the insertion part 72 which can penetrate the cylindrical pipe 73 was illustrated, it cannot be overemphasized that a square etc. may be penetrated if it is not set as the structure which can rotate.

(Modification 1)
In the above-described embodiment, the configuration in which the support plate 71 includes one insertion portion 72 is exemplified. However, the support plate 71 may be configured to include a plurality of insertion portions. FIG. 12 is a conceptual diagram illustrating a support plate 71 provided with a plurality of insertion portions 72a to 72h.

  As shown in FIG. 12, in the first modification, the support plate 71 is provided with insertion portions 72 a to 72 h at predetermined intervals. Here, when the above-described center of gravity G is aligned with the position of the insertion portion 72c, the cylindrical portion 73 is inserted into the insertion portion 72c and lifted to keep the fixing portion 1 substantially horizontal as in the above-described embodiment. Can be lifted in the wet state. Further, by inserting the cylindrical pipe 73 into an insertion part such as the insertion parts 72b and 72d that is slightly deviated from the center of gravity G and lifting it, it is possible to obtain a force for raising by the weight of the fixed part 1.

(Modification 2)
In the above-described embodiment, the configuration in which the inner diameter of the insertion portion 72 and the outer diameter of the cylindrical pipe 73 are substantially the same is illustrated. However, a configuration in which the inner diameter of the insertion portion 72 is sufficiently larger than the outer diameter of the cylindrical pipe 73 and the position of the cylindrical pipe 73 can be adjusted inside the insertion portion 72 may be adopted.

  FIG. 13 is a conceptual diagram illustrating the position adjustment of the cylindrical pipe 73 inside the insertion portion 72. As shown in FIG. 13, the cylindrical pipe 73 is configured to be supported from three directions at intervals of 120 ° by support screws 721 to 723 inside the insertion portion 72. By adjusting the support screws 721 to 723, the position of the cylindrical pipe 73 with respect to the center of gravity G can be adjusted. For example, by tightening the support screw 721 and loosening the support screws 722 and 723, the position of the cylindrical pipe 73 can be made lower than the center of gravity G.

  According to at least one embodiment described above, the diagnostic imaging apparatus can be easily transported.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention.
