- FIG. 2 is a schematic plan view showing the structure of the movable carriage 13.
- the state shown in FIG. 2 is a diagram showing a state in a normal operation state.
- the motor shaft 29 of the motor 19 is connected to the propeller shaft 31 via the clutch 21. That is, the propeller shaft 31 is rotated by the motor 19 when the clutch 21 is engaged.
- the rotational force of the propeller shaft 31 is transmitted to the shaft 37 via gears 33 and 35.
- the drive wheel 15 is fixed to the shaft 37. That is, the driving wheel 15 can be driven by transmitting the rotational force from the propeller shaft 31 to the shaft 37. Therefore, the movable carriage 13 can be run.
- the clutch operating unit 27 is connected to the clutch 21.
- the clutch operating unit 27 is a part that connects and disconnects the clutch plate and the flywheel that constitute the clutch 21. In the normal operation state, the clutch 21 is always kept connected. That is, the driving force of the motor 19 is always transmitted to the shaft 37 via the propeller shaft 31 and the gears 33 and 35.
- An operation amount detection unit 41 is provided in the vicinity of the cart operation unit 23.
- the operation amount detection unit 41 detects the operation amount of the cart operation unit 23.
- an operation switch 43 is provided in the vicinity of the cart operation unit 23.
- the operation switch 43 is a part for operating the clutch operating unit 27.
- the operation switch 43 and the clutch operating unit 27 are configured by, for example, a hydraulic circuit or a mechanical mechanism without using electric power.
- FIG. 3 (a) is a schematic view of the cart operation unit 23.
- the cart operation unit 23 is an operation lever, for example, and returns to its original state by an elastic member when the hand is released.
- the operation amount detection unit 41 detects the operation amount. That is, the displacement amount of the cart operation unit 23 is detected.
- the operation amount detection unit 41 includes, for example, a position sensor and a slide resistance.
- the operation amount detection unit 41 drives the motor 19 according to the operation amount of the carriage operation unit 23.
- the operation amount detection unit 41 reduces the rotation speed of the motor 19 when the operation amount of the carriage operation unit 23 is small, and increases the rotation number of the motor 19 as the operation amount of the carriage operation unit 23 increases. To control. Therefore, the user can adjust the moving speed of the movable carriage 13 according to the operation amount of the carriage operation unit 23.
- the motor 19 stops the rotation of the propeller shaft 31 by its own brake. Therefore, the drive wheel 15 does not rotate. Thus, in a state where the user releases his / her hand, the brake is always applied.
- the maximum value of the operation amount of the cart operation unit 23 is mechanically limited. As shown in FIG. 3 (b), the maximum operation amount of the cart operation unit 23 is Bmax. The carriage operation unit 23 cannot be operated with a displacement amount larger than this. Therefore, when the operation amount of the carriage operation unit 23 is Bmax, the movable carriage 13 travels at the maximum speed.
- an operation switch 43 is provided in the operation direction of the cart operation unit 23.
- the cart operation unit 23 and the operation switch 43 do not come into contact with each other. That is, even if the cart operation unit 23 is operated, the operation switch 43 is not operated.
- FIG. 4 is a schematic plan view showing an operation structure of the movable carriage 13 in the manual operation state.
- the changeover switch 25 is switched. By switching the changeover switch 25, a manual operation state can be set.
- the changeover switch 25 When the changeover switch 25 is switched, the power supply to the motor 19 is cut off. Therefore, even if the cart operation unit 23 is operated, the motor 19 does not operate. That is, the motor 19 is always braked. In this state, the clutch operating unit 27 can be operated by the operation switch 43.
- the operation switch 43 is operated as follows.
- a spacer 45 is disposed in the vicinity of the cart operation unit 23 in the normal operation state.
- the changeover switch 25 is operated, as shown in FIG. 5 (b), the spacer 45 is automatically or manually inserted into the gap between the carriage operation unit 23 and the operation switch 43 (arrow C in the figure).
- the operation switch 43 is pushed in accordance with the operation amount of the cart operation unit 23 (arrow E in the figure). That is, the operation switch 43 can be operated by the cart operation unit 23. If the operation switch 43 can be operated, the spacer 45 is not always necessary.
- the maximum value of the operation amount of the operation switch 43 is substantially the same as the maximum value (Bmax) of the operation amount of the carriage operation unit 23 in the normal operation state. That is, the gap between the carriage operation unit 23 and the operation switch 43 and the thickness of the spacer 45 are substantially the same. In this way, the maximum push amount of the operation switch 43 via the spacer 45 is substantially equal to the maximum operation amount (Bmax) of the carriage operation unit 23 in the normal operation state. For this reason, the feeling of operation between the normal operation state and the manual operation state does not change for the user.
- the clutch operating unit 27 When the operation switch 43 is pushed in, the clutch operating unit 27 operates according to the push amount of the operation switch 43.
- the clutch operating unit 27 can disconnect the clutch 21 that is always connected during normal operation.
- the clutch plate is moved by a hydraulic actuator or the like with respect to the normal operation state where the clutch plate and the flywheel are pressed by the elastic member, and a gap can be formed between the flywheel and the flywheel.
- the clutch 21 is operated via the operation transmission mechanism by the operation of the carriage operation unit 23. That is, in the above-described example, the operation transmission mechanism is operated according to the push-in amount by pushing the operation switch 43, the spacer 45 that can be inserted and removed between the operation switch 43 and the carriage operation unit 23, and the operation switch 43.
- a clutch operating unit 27 that operates the clutch 21 is configured.
- the operation transmission mechanism is not limited to the above example.
- the operation mechanism of the clutch operation unit 27 with respect to the operation switch 43 does not need to be hydraulic, and may be another mechanical link structure. However, it is desirable that the mechanism does not use power.
- FIG. 6 is a conceptual diagram showing the relationship of the clutch clearance (the clearance between the clutch plate and the flywheel; the same applies hereinafter) with respect to the operation amount of the carriage operation unit 23.
- the operation amount of the carriage operation unit 23 and the clutch clearance are substantially proportional. Increasing the amount of operation of the carriage operation unit 23 increases the clutch clearance. That is, the clutch plate and the flywheel are easily slipped.
- the clutch clearance is 0. That is, the state is the same as the normal operation state. Therefore, the movement of the shaft 37 is stopped by the brake of the motor 19. Therefore, when the operation amount of the carriage operation unit 23 is 0, the movable carriage 13 is not moved by the brake of the motor 19 as in the normal operation state.
- the clutch clearance gradually increases. Therefore, the clutch plate and the flywheel slip. For this reason, the movable carriage 13 can be moved. Further, the larger the operation amount, the larger the gap between the clutches, and the greater the slip between the clutch plate and the flywheel. Accordingly, the movement resistance of the movable carriage 13 is reduced. For this reason, the movable carriage 13 can be easily moved.
- the maximum manipulated value Bmax and B1 can be substantially matched, but B1 is preferably about 70 to 80% of Bmax. If B1 is too small with respect to Bmax, it will be difficult to finely adjust the brake by changing the operation amount. Also, if B1 gets too close to Bmax, the brake will be effective just by loosening the carriage operation unit 23 a little. Therefore, unless the carriage operation unit 23 is always operated at the maximum amount, the movable carriage 13 is not in a free state (a state where there is no influence of the brake of the motor 19), and the burden on the user is large. Therefore, it is desirable that B1 is approximately 70 to 80% of Bmax.
- the mobile X-ray apparatus 1 As described above, according to the mobile X-ray apparatus 1 according to the present embodiment, even when the battery 17 is exhausted, the mobile X-ray apparatus 1 can be manually moved by operating the mobile carriage 13. At this time, since the brake of the motor 19 is used, it is safe.
- the normal operation state and the manual operation state can be operated by the same cart operation unit 23, and the operation method is the same. Further, the operation amount of the cart operation unit 23 in the normal operation state and the manual operation state is substantially the same. Therefore, the user can operate the mobile carriage 13 without a sense of incongruity even in the manual operation state.
- the brake can be gradually applied according to the operation amount of the carriage operation unit 23. For this reason, it is possible to prevent sudden braking. In addition, it is not necessary to provide a brake for manual operation.
- FIG. 7 is a diagram showing the mobile X-ray apparatus 50. As shown in FIG. In the following description, components having the same functions as those of the mobile X-ray apparatus 1 are denoted by the same reference numerals as in FIGS. 1 to 6 and the like, and redundant description is omitted.
- the mobile X-ray device 50 has substantially the same configuration as that of the mobile X-ray device 1, but differs in that a voltage detection unit 51 and a switch operation unit 53 are provided.
- the voltage detection unit 51 detects the voltage of the battery 17. Therefore, the voltage detector 51 can detect the remaining amount of electricity in the battery 17.
- the switch operation unit 53 connected to the voltage detection unit 51 switches the changeover switch 25. That is, when the remaining amount of the battery 17 becomes equal to or less than a predetermined value, the normal operation state is automatically switched to the manual operation state.
- the motor 19 may cause the voltage detector 51 to detect a decrease in the remaining amount of the battery 17 while the mobile X-ray apparatus is traveling. However, it is dangerous if the changeover switch 25 is automatically switched during traveling. Therefore, before switching the changeover switch 25, the switch operating unit 53 first gradually stops the power supply from the battery 17 to the motor 19, and first gradually stops the mobile carriage 13. After the motor 19 is completely stopped, the switch operation unit 53 switches the changeover switch 25.
- the switch operation unit 53 may be inserted between the cart operation unit 23 and the operation switch 43 by further moving the spacer 45 after the changeover switch 25 is switched.
- the same effects as those of the first embodiment can be obtained. Further, the voltage detection unit 51 can automatically switch to the manual operation state when the remaining battery level is low.
- FIG. 8 is a diagram showing the mobile X-ray apparatus 60.
- the mobile X-ray device 60 has substantially the same configuration as the mobile X-ray device 50, but differs in that a storage unit 61 is provided.
- the storage unit 61 stores a use schedule of the X-ray apparatus 3.
- electric power is supplied from one battery 17 to both the X-ray device 3 and the motor 19.
- the use schedule of the day is stored in the storage unit 61.
- the number of times of X-ray irradiation is stored in the storage unit 61.
- the storage unit 61 stores the amount of electricity used for one X-ray irradiation.
- the voltage detection unit 51 calculates the minimum remaining electric power necessary for irradiating X-rays from the scheduled number of X-ray use and the amount of electricity used per time. Note that after using the X-ray device 3 (after X-ray irradiation), the number of uses is subtracted from the scheduled number of times of use, and the remaining amount of electricity necessary for the remaining number of times of X-ray irradiation is calculated each time. Such calculation of the minimum required amount of electricity may be performed using a separate control unit.
- the voltage detection unit 51 detects the remaining amount of electricity in the battery 17.
- the switch operation unit 53 switches the changeover switch 25.
- the changeover switch 25 is switched.
- the voltage detection unit 51 can secure an electric capacity that allows a predetermined number of X-ray irradiations. For this reason, after moving the mobile X-ray apparatus 60, it can be prevented that X-ray irradiation cannot be performed due to insufficient battery capacity.
- FIG. 9 is a diagram showing the mobile X-ray apparatus 70. As shown in FIG.
- the mobile X-ray device 70 has substantially the same configuration as the mobile X-ray device 50, but differs in that an alarm unit 71 is provided.
- the alarm unit 71 When the voltage detection unit 51 causes the remaining battery level to fall below a predetermined level (below the remaining warning level), the alarm unit 71 is first activated. The warning unit 71 warns the user that the remaining battery level is low by sound, light, or the like.
- the switch switch 53 is switched by the switch operation unit 53.
- the remaining amount of battery to be switched to the manual operation state may be the minimum amount of electricity required to drive the motor 19, and as described above, a separate storage unit is provided and necessary for the remaining X-ray irradiation. It may be the minimum amount of electricity. In any case, it suffices that the user can recognize the alarm unit 71 that the remaining battery level has decreased before switching to the manual operation state.
- the same effect as in the second embodiment can be obtained.
- the battery 17 is low, and instead of suddenly switching to the manual operation state, an alarm for switching to manual operation is issued in advance. For this reason, the user can be careful about running out of the battery, such as refraining from unnecessary cart operations.
- FIG. 10 is a diagram showing the mobile X-ray device 80
- FIG. 11 (a) is a schematic cross-sectional view in the vicinity of the drive wheel 15 showing a state where the clutch 21a is connected
- FIG. 11 (b) is connected
- 11 (c) is a schematic cross-sectional view of the vicinity of the drive wheel 15 showing a state in which the clutch 21a is disengaged
- FIG. 11 (d) is a schematic view showing the clutch 21a in a disengaged state.
- the mobile X-ray device 80 is different from the mobile X-ray device 1 and the like in that the motor 19 is directly connected to the drive wheel 15 without using a propeller shaft or the like.
- the motor 19 is directly connected to each drive wheel 15 on both sides. That is, the motor shaft 29 of the motor 19 serves as the rotation shaft of the drive wheel 15.
- the drive wheel 15 and the motor shaft 29 are connected via a clutch 21a.
- the motor shaft 29 is provided with a clutch operating unit 27.
- the clutch 21a is provided with a portion corresponding to a flyhole (hereinafter referred to as flywheel equivalent portion 87) on the drive wheel 15 side, and a motor shaft 29 inside thereof.
- flywheel equivalent portion 87 a portion corresponding to the clutch plate
- the clutch plate equivalent portion 85 is divided into a plurality of portions in the circumferential direction, and is normally pressed against the flywheel equivalent portion 87 on the outer peripheral side. Therefore, power is transmitted from the clutch plate equivalent portion 85 to the flywheel equivalent portion 87.
- this state is always in this state, so that the driving wheel 15 is rotated by the power from the motor shaft 29.
- the drive wheel 15 is rotatably attached to the movable carriage 13 by a tubular support member 81, a bearing 83, and the like separately from the motor shaft 29. That is, the motor shaft 29 is disposed inside the support member 81 fixed to the drive wheel 15.
- the support member 81 is rotatably supported by a bearing 83 provided on the movable carriage 13.
- the clutch operating unit 27 is operated by the operation switch 43.
- the operation switch 43 is pushed, as shown in FIGS. 11 (c) and 11 (d), the divided clutch plate equivalent portion 85 is pulled back to the center side (in the direction of arrow G in the figure). Therefore, a gap is generated between the clutch plate equivalent portion 85 and the flywheel equivalent portion 87, causing a slip.
- the drive wheel 15 rotates without being affected by the brake of the motor 19. Even in this case, the drive wheel 15 can be rotated by being supported by the movable carriage 13 by the support member 81.
- the same effect as in the first embodiment can be obtained. Further, even when the motor 19 and the drive wheel 15 are directly connected, the same operation can be performed. Such a mechanism can also be performed via an excitation clutch between the motor 19 and the drive wheel. While the motor 19 and the battery 17 are electrically connected, the torque of the motor 19 may be transmitted to the drive wheel 15, and the clutch may be disengaged when the connection is electrically interrupted.
