Abstract

(57) [Summary] [Purpose] Power is not supplied to the motor control circuit in the standby state where the brake is not released. [Structure] In a motor-driven mobile X-ray generator that uses a battery as a power source, interlocking switches that mechanically interlock with a brake release switch, and power supply to the brake release circuit and the motor control circuit by operating those switches It has a circuit to cut off.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a motor-driven mobile X-ray generator that uses a battery as a power source.

[0002]

[Prior Art]

 As shown in FIG. 1, a motor-driven mobile X-ray generator that uses a battery 1 as a power source is normally in a state in which a brake 7 is applied for safety. When the operator turns on the power switch 2 on the panel, power is supplied to the motor control circuit 6. When the operator operates the brake release switch 3, power is supplied to the brake release circuit 5 only for that time to release the brake 7, and the rotation of the motor 8 is controlled by operating the handle 4 to move the device. Be seen.

[0003]

[Problems to be solved by the device]

 However, since the power switch 2 on the panel surface is turned on and the motor control circuit 6 is operating in the standby state where the brake 7 is not released, the power consumption of the battery is wasted.

An object of the present invention is to solve the above problems and to provide a mobile X-ray generator in which power is not supplied to a motor control circuit in a standby state where a brake is not released.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned subject, the composition of the present invention is as follows. That is, in a motor-driven mobile X-ray generator that uses a battery as a power source, interlock switches that mechanically interlock with the brake release switch, and the brake release circuit and the motor control circuit are operated by operating those switches. It has a circuit that cuts off the power supply.

[0006]

[Action]

 When the brake release switch is operated, power is supplied to the brake release circuit and the motor control circuit through the contacts of the switch mechanically interlocked with it.

[0007]

【Example】

 An embodiment of the present invention will be described below based on an embodiment shown in the drawings.

In FIG. 2, a brake release circuit 5 and a motor control circuit 6 are connected in parallel to a battery 1 which is a DC power source. Reference numeral 7 is a brake, and 8 is a trolley driving motor. Reference numeral 4 is a handle, and the rotation direction and rotation speed of the motor 8 are changed by its operation. A brake release switch 3 is connected in series to the brake release circuit 5. Numeral 2 is a power switch on the board installed on the truck.

Now, a series circuit of the interlock switch 10 and the relay coil 9a is connected in parallel to the brake release circuit 5 and the motor control circuit 6. The interlocking switch 10 mechanically interlocks with the brake release switch 3. A relay contact 9b is connected in series to the brake release circuit 5 and the motor control circuit 6.

The operation state will be described above. Even when the power switch 2 is closed, when the device is not moved, the brake release switch 3, the interlock switch 10 and the relay contact 9b are opened and the brake 7 is applied.

Next, when moving the device, when the operator closes the brake release switch 3, the interlock switch 10 is closed and power is supplied to the relay coil 9a, and the contact point 9b is closed. . As a result, power is supplied to the brake release circuit 5 and the motor control circuit 6, and by operating the handle 4, the device can be moved.

The present invention is not limited to the above-described embodiments and embodiments, and includes various modifications without departing from the spirit and scope of the utility model registration request.

[0013]

[Effect of the device]

 Electric power is supplied from the battery only for the time the operator operates the brake release switch, so there is no unnecessary power consumption.
