Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a mobile X-ray apparatus, and more particularly to a mobile X-ray apparatus suitable for traveling operability and stability during moving and photographing.

[0002]

[Prior Art]

 Conventionally, there have been a front wheel drive system (F F system) having a main wheel as a front wheel and a rear wheel drive system (FR system) having a main wheel as a rear wheel as a moving system of a mobile X-ray apparatus. In these two types of mobile X-ray equipment, the position of the X-ray tube equipment during movement is different from that during radiography, so during photography, the center of gravity of the equipment near the main wheels moved forward or backward. Will end up. Therefore, there has been proposed a device in which the main wheels are movably mounted between the free wheels provided in the front and rear of the bogie, and the main wheels are moved even when the X-ray tube device is rotated to respond to changes in the center of gravity. .. However, since this device increases the number of parts, the two conventional methods are used, and the FR method, which is more advantageous for small turns, is often used.

A conventional FR-type mobile X-ray apparatus will be described with reference to FIGS. 2 and 3. In this mobile X-ray device, an X-ray device 1 accommodating an X-ray high voltage device, an X-ray control device, and the like and a support 11 are mounted on a carriage 2. A main wheel 3 is provided on the rear side of the carriage 2 and a free wheel 4 is provided on the front side. An arm 7 is slidably attached to the column 11, and an X-ray tube device 8 and a movable diaphragm 9 are provided at the tip of the arm 7. When moving, the arm 7, the X-ray tube device 8, and the movable diaphragm 9 are rotated toward the X-ray device 1 side with the axis of the column 11 as the center of rotation 10 to be on standby, and during imaging, the arm 7 is rotated toward the subject side for imaging. Was there.

[0004]

[Problems to be solved by the device]

 In the conventional FR-type mobile X-ray device, the X-ray tube device rotates about the axis of the column as described above, and therefore the column, arm, X-ray tube device, and movable aperture are set at the moving position and the photographing position. The center of gravity of the combination moves back and forth, and as a result, the center of gravity of the entire device also moves back and forth. Therefore, when the direction of the X-ray tube device is changed while the X-ray tube device is in the photographing position, the center of gravity is moving forward, so that the load on the free wheel in front of the X-ray tube becomes large and the operation becomes heavy.

Therefore, an object of the present invention is to provide a mobile X-ray apparatus which can be stably operated without changing the center of gravity of the apparatus even when the X-ray tube apparatus is rotated to a moving position and a photographing position. It is in.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, an X-ray high-voltage device, an X-ray control device, and a rotatable column are mounted on a carriage, and the main wheels and free wheels provided on the truck move the same, and at the same time, the column is moved. A movable X-ray apparatus having a movable telescopic arm, and an X-ray tube device and a movable diaphragm attached to the tip of the arm, wherein the center of rotation of the column is the column, arm, X-ray tube device, and movable diaphragm. It is the center of weight of the combination.

[0007]

[Action]

 Even if the rotation axis of the support is placed at the center of weight of the combination of the support, the arm, the X-ray tube device, and the movable diaphragm, and the X-ray tube device is rotated to the moving position and the photographing position, the center of gravity of the entire device does not change. Operability is always stable.

【Example】

 An embodiment of the present invention will be described below with reference to FIG. FIG. 1 is a side view of an FR type mobile X-ray apparatus using the present invention. 1 is an X-ray device that houses an X-ray high-voltage device and an X-ray control device, 2 is a dolly on which the X-ray device 1 and the support 6 are mounted, and 3 is a main wheel for moving the dolly 2 and is an X-axis of the dolly 2. It is provided on the line device 1 side, so-called rear side, and moves electrically. Numeral 4 is a free wheel for moving and changing the direction of the trolley 2, which is provided on the front side of the stanchion 2 side of the trolley 2. Reference numeral 5 denotes a handle which is held when the apparatus is moved, 6 is a column which holds an arm 7, an X-ray tube apparatus 8 and a movable diaphragm 9, and is rotatably attached to the carriage 2. An extendable arm 7 supports an X-ray tube device 8 and a movable diaphragm 9 at its tip. Reference numeral 10 is the center of rotation of the column 6.

Next, the operation of this embodiment will be described. First, the center of gravity G of the entire mobile X-ray apparatus is placed on the side of the main wheels so as to make a small turn. Further, in order to balance the weight of the combination of the support 6, the arm 7, the X-ray tube device 8 and the movable diaphragm 9, the center of rotation 10 of the support 6 is separated from the center of the shaft of the support 6 and the X-ray device 8 side. The center of gravity G1 of the combination of the column 6, the arm 7, the X-ray tube device 8 and the movable diaphragm 9 does not change even if the column 6 is rotated. In other words, since the center of gravity G between the moving position and the shooting position is always constant, if the user wants to move a little in the shooting position, he can make a small turn and can easily move. Also, when the X-ray tube device 8 is rotated to the imaging position and the arm 7 is extended, the center of gravity G of the device moves slightly forward, but when the arm 7 is extended, it hardly moves, so at this time It is not necessary to consider the change of the center of gravity G of.

[0010]

[Effect of the device]

 According to the present invention, since the center of rotation of the column is placed at the center of weight of the combination of the column, arm, X-ray tube device and movable diaphragm, even if the column is rotated to the moving position or the photographing position, the center of gravity of the entire device does not move. The operability is always stable.
