Description

[Detailed description of the device] [Industrial applications]

 The present invention relates to a mobile X-ray apparatus, and more particularly, to a mobile X-ray apparatus suitable for facilitating a steering operation when changing the moving direction of a carriage and reducing the operator's labor in the steering operation.

[0002]

[Prior Art]

 In the conventional mobile X-ray apparatus, a main wheel (driving wheel) which is driven by power and a non-steering main wheel which is driven and which is rotatable and which determines a moving direction are arranged on the front and rear of the bogie or vice versa. It was configured to operate a traveling switch attached to a rod-shaped traveling handle provided at the rear for pushing the operator's hand, and to move the entire device forward and backward while controlling the traveling speed by operating this switch. A heavy load such as an X-ray tube device is loaded on the trolley, and the overall weight of the mobile X-ray device is considerable (for example, 400 kg to 500 kg). The operator manually pushes the traveling handle in either the left or right direction so as to face the vehicle.

[0003]

[Problems to be solved by the device]

 The steering of the carriage performed while controlling the moving speed of the mobile X-ray device requires a large amount of the pressing force of the traveling handle because the weight of the entire mobile X-ray device is large. The reality is that you cannot change the direction unless you operate it. Therefore, there is a problem in that the operator is forced to make a great deal of effort during the steering operation.

In view of the above-mentioned problems of the prior art, the present invention provides a mobile X-ray device that facilitates a steering operation when changing the moving direction of a trolley and can reduce an operator's labor in the steering operation. The purpose is to do.

[0005]

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention provides a trolley provided with a main wheel driven by power and a freely rotatable follower wheel that determines a moving direction, and an operator when the trolley moves. In a mobile X-ray device equipped with a rod-shaped traveling handle provided at the rear of a bogie that serves as a steering member for steering, a motor for driving the driven wheels and a rotation direction of the motor are selected. And a pressure sensor provided at the left and right ends of the traveling handle that can set the rotation angle of the motor according to the pressing force.

[0006]

[Action]

 With the above configuration, the rotation direction of the motor that drives the driven wheels can be changed by the operator pressing one of the pressure sensors provided at the left and right ends of the traveling handle with a slight force. It will be selected and it will be possible to change the direction of the driven wheel to either left or right. Therefore, by setting in advance which pressure sensor should be pressed to move the slave wheel, it becomes possible to easily orient the slave wheel in the desired direction. The angle by which the direction of the driven wheel is changed is controlled by the rotation angle (rotation amount) of the drive motor that is set by linking to the magnitude of the force pressing the pressure sensor.

As described above, in the steering of the bogie, the direction of the follower wheels and the angle in that direction are set by only slight adjustment of the force of the operator who presses the pressure sensor provided on the running handle through the running handle. Since it becomes possible, the operation becomes extremely easy, and the operator's effort is small.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. 1 is an external perspective view of the main part of the mobile X-ray apparatus, FIG. 2 is a plan view for explaining the steering operation of FIG. 1, and FIG. 3 is a view on arrow III-III of FIG.

In the figure, reference numeral 1 denotes a trolley, on which a heavy load such as an X-ray tube device is placed, and a traveling handle 9 serving as a hand pushing member for steering by an operator is provided at a rear portion thereof. It has been burned. Main wheels 2 are provided on the left and right of the rear side of the bogie 1, and are driven by a driving device 3 by power. Denoted at 4 are sub wheels provided on the left and right of the front end of the bogie 1, and the sub wheels 4 are rotatably supported around a vertical axis supported by a bearing 11. Reference numeral 6 denotes a sprocket fixed to the vertical axis of each driven wheel 4, 7 denotes a sprocket fixed to a motor 8 for driving the driven wheel 4, and the sprockets 6 and 7 are connected via a chain 5. The pressure sensors 10a and 10b are attached to the left and right ends of the traveling handle 9, and are configured to detect the pressing force of the operator acting on the left and right ends of the traveling handle 9 and turn on the motor 8. .. By pressing one of the left and right pressure sensors 10a and 10b, either the left or right rotation direction of the motor 8 is selected, and at the same time, the motor 8 is rotated according to the magnitude of the pressing force. The rotation angle (rotation amount) is set. Here, the pressure sensors 10a and 10b to be pressed and the rotation direction of the motor 8 are predetermined to be combined.

Next, the operation of the above configuration will be described. When the operator presses either one of the pressure sensors 10a and 10b provided at the left and right ends of the traveling handle 9 with a slight force, the pressing force is detected through the pressed pressure sensor. Then, the motor 8 is turned on. In this case, since the combination of the pressure sensor to be pressed and the rotation direction of the motor 8 is predetermined, for example, when the direction is changed to the right as shown in FIG. The pressure is detected by the pressure sensor 10b in the direction of arrow L, the motor 8 is turned on, and the motor 8 is rotated in the direction of arrow R shown in FIG. The rotation of the motor 8 causes each of the driven wheels 4 to rotate the sprockets 6 via the chain 5, and the direction thereof can be changed to the direction shown by the dotted line in the figure.

Since the angle for changing the direction of each of the driven wheels 4 is set by linking with the magnitude of the force when pressing the pressure sensor 10b, the traveling pressure is adjusted according to the operator's intention to change the direction. By pushing the handle 9, the motor 8 can be rotated through the pressure sensor 10b by an amount corresponding to the pushing force according to the intention, and the direction change angle of each driven wheel 4 can be easily and arbitrarily set. To do.

As described above, the steering of the trolley 1 can be performed by a slight adjustment of the force of the operator who presses the pressure sensor 10a or 10b provided on the left and right of the traveling handle 9 so that the direction of the driven wheel 4 and the angle of the direction of the driven wheel 4 can be controlled. Therefore, the operation becomes extremely easy, and the operator's labor is sufficient.

[Effect of the device]

 As described above, according to the present invention, the motor that drives the rotatable follower wheel that determines the moving direction and the rotation direction of the motor are selected, and the rotation angle of the motor can be set according to the pressing force. Since it is configured with pressure sensors provided at the left and right ends of the handle, it has the effect of facilitating the steering operation when changing the moving direction of the carriage and reducing the operator's effort in the steering operation.
