【産業上の利用分野】[Industrial application]

本考案は移動形X線装置に係り、特に移動時及び撮影時の走行操作性、安定性 に好適な移動形X線装置に関する。 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.

【従来の技術】[Prior Art]

移動形X線装置の移動方式として従来は主車輪を前輪に持つ前輪駆動方式(F F方式)と、主車輪を後輪に持つ後輪駆動方式(FR方式)とがあった。この二 つの方式の移動形X線装置では、移動時と撮影時でのX線管装置の位置が異なる ため、撮影時では移動時で主車輪付近にあった装置の重心が前または後に移動し てしまう。そのため、台車の前後に設けられた自在車輪間に主車輪を移動可能に 取付け、X線管装置を回転させても主車輪を移動させて重心位置の変化に対応す る装置が提案されている。しかし、この装置では部品の数が増えてしまうため、 従来からの二つの方式が用いられており、さらに小回りに有利なFR方式が多用 されている。 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.

【0003】 従来のFR方式の移動形X線装置を図2及び図3を用いて説明する。この移動 形X線装置は、X線高電圧装置やX線制御装置等を収納したX線装置1と支柱1 1を台車2に搭載している。この台車2の後方に主車輪3を備え、前方には自在 車輪4を備える。この支柱11にはアーム7が摺動可能に取り付けられており、 このアーム7の先端にX線管装置8及び可動絞り9が設けられている。そして、 移動時には支柱11の軸を回転中心10として、アーム7、X線管装置8、可動 絞り9をX線装置1側へ回転して待機させ、撮影時には被検体側へ回転して撮影 していた。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.

【考案が解決しようとする課題】[Problems to be solved by the device]

上記従来のFR方式の移動形X線装置は、前述の通りX線管装置が支柱の軸中 心で回転するため、移動位置と撮影位置では支柱、アーム、X線管装置、可動絞 りの組合せの重心が前後してしまい、その結果装置全体の重心も前後に移動する 。そのため、X線管装置を撮影位置にしたまま方向転換をする場合には、重心が 前方へ移動しているので前方の自在車輪への負担が大きくなり操作が重いものと なっていた。 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.

【0005】 そこで本考案の目的は、X線管装置を移動位置及び撮影位置に回転させても、 装置の重心位置の変化がなく安定した操作が可能な移動形X線装置を提供するこ とにある。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.

【課題を解決するための手段】[Means for Solving the Problems]

上記目的を達成するために、X線高電圧装置とX線制御装置と回転可能な支柱 を台車に搭載させ、この台車に設けられた主車輪と自在車輪とにより移動すると 共に、前記支柱上を移動する伸縮自在のアームと、このアームの先端に取り付け られたX線管装置及び可動絞りとを有する移動形X線装置において、上記支柱の 回転中心を支柱、アーム、X線管装置、可動絞りの組合せの重量中心位置とした ものである。 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.

【実施例】【Example】

以下、本考案の一実施例を図1を用いて説明する。図1は本考案を用いたFR 方式の移動形X線装置の側面図である。1はX線高電圧装置やX線制御装置を収 納するX線装置、2はX線装置1及び支柱6を搭載する台車、3は台車2を移動 させるための主車輪で台車2のX線装置1側いわゆる後側に設けられ電動で移動 する。4は台車2の移動及び方向転換のための自在車輪で台車2の支柱6側いわ ゆる前側に設けられる。5は装置を移動させるときに持つハンドル、6はアーム 7、X線管装置8、可動絞り9を保持する支柱で回転自在に台車2に取り付けら れている。7は伸縮自在のアームで先端にX線管装置8及び可動絞り9を支持し ている。10は支柱6の回転中心である。 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.

【0009】 次に本実施例における動作を説明する。まず、この移動形X線装置全体の重心 Gは小回りが利くように主車輪側に置かれている。さらに、支柱6の回転中心1 0は支柱6、アーム7、X線管装置8、可動絞り9の組合せの重量とバランスを 取るために、支柱6の軸中心より離れてX線管装置8側に設けており、支柱6を 回転させても支柱6、アーム7、X線管装置8、可動絞り9の組合せの重心G1 は変化しない。つまり、移動位置と撮影位置の重心Gは常に一定であるため、撮 影位置の状態で少し移動させたいという場合に、小回りができ楽に移動ができる 。また、撮影位置にX線管装置8を回転させアーム7を伸長させた場合に装置の 重心Gは若干前方へ移動するが、アーム7を伸長させた状態ではほとんど移動さ せないため、この時の重心Gの変化を考慮しなくてもよい。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.
