Description

  The present invention relates to a portable driving device, and more particularly to a portable driving device that manually operates a driving device.

  For example, passenger conveyors such as elevators and escalators are automatically operated during normal operation. However, an elevator, an escalator, or the like may be manually operated by an operator at the time of equipment maintenance and inspection or when repairing a failure. In that case, the operator performs a maintenance check or a repair of a failure while operating the elevator or the escalator using the portable driving device.

  When carrying out maintenance inspections and repairs of passenger conveyors such as elevators and escalators with this portable operating device, operate and move the elevators and escalators with both hands, and perform maintenance inspections after the operation is completed. It is preferable in terms of work safety to perform work and repair of breakdown.

  FIG. 3 shows an example of a conventional portable driving device. The portable operating device 100 is provided with a first switch 102 and second switches 103a and 103b. The first switch 102 is a “RUN” switch that allows the operator to select and operate an ON / OFF state of operation of the device. In general, the first switch 102 is normally in an OFF state, and is a so-called “push button” system in which the switch 102 is turned on when the switch 102 is pressed and turned off when the switch 102 is pressed again.

  The second switches 103a and 103b are “UP / DOWN” switches that allow the operator to select and operate the operation direction of the device. In general, the second switches 103a and 103b are normally in a neutral state. When the switch 103a is pressed, the passenger conveyor is raised, and when the switch 103a is pressed again, the second switch 103a and 103b is in a neutral state. Further, the passenger conveyor is lowered by pressing the switch 103b, and is in a neutral state by pressing the switch 103b again.

  In terms of work safety, it is preferable that this portable driving device is used to operate the passenger conveyor with both hands. However, since the conventional portable driving apparatus is a push button system, it can be operated with one hand. If the operation of the passenger conveyor is performed with both hands, the operation cannot be started unless the operation is completed to complete the movement of the passenger conveyor. Therefore, the operator may operate with one hand in order to increase work efficiency.

  If the portable operating device is operated with one hand when performing maintenance and inspection work on the passenger conveyor or repairing a malfunction, there is a risk that a disaster such as the opposite hand getting caught in a rotating object around the passenger conveyor may occur. This is because an accident due to an operation error is likely to occur because the movement of the passenger conveyor, the maintenance inspection work, and the repair of the failure are performed at the same time.

  An object of the present application is to provide a portable driving device that solves such a problem, causes an operator to perform a two-handed operation, and prevents a disaster that occurs when the operator performs a one-handed operation.

  In order to achieve the above object, a portable operating device according to the present invention is a portable operating device for manually operating a driving device, wherein a first switch that allows an operator to select and operate an ON / OFF state of the device operation, And a driving operation unit provided with a second switch that causes the operator to select and operate the driving direction of the device, a signal transmitted from the first switch to hold the driving in an ON state, and a second switch An operation control unit that transmits an operation command in the operation direction to the device when receiving the signal that holds the operation direction of the device transmitted from the device, and the first switch and the second switch are The configuration is such that the operator cannot be held simultaneously with one hand.

  With the above configuration, the portable driving device includes a first switch that allows the operator to select and operate the device operation ON / OFF state, and a second switch that causes the operator to select and operate the device. As a configuration that cannot be held simultaneously by one hand, the operator can be encouraged to drive both hands. Thereby, the disaster which generate | occur | produces when an operator carries out one-hand drive can be prevented. That is, one-handed operation can be made impossible by using a configuration in which both switches do not function unless they are held with both hands.

  In addition, the portable operating device is configured such that the first switch is normally in an OFF state, and returns to the OFF state if the ON state is not maintained even if the switch is operated to the ON state. The neutral state is usually set, and it is preferable that the switch returns to the neutral state if the switch is not operated even when one of the operation directions is selected. Thereby, even if the operator tries to operate with one hand, the switch returns to the OFF state or the neutral state, and the operation control unit does not transmit an operation command to the device. Thereby, it is possible to prevent a disaster that occurs when the operator performs a two-hand operation and the operator performs a one-hand operation.

  In addition, the portable operating device returns to the OFF state by the built-in spring if the first switch does not hold the ON state of the switch, and is built if the second switch does not hold the switch in any of the operating directions. It is preferable to return to the neutral state by the spring. Thereby, the switch must be held by the spring built in the switch.

  In the portable operating device, the first switch and the second switch preferably include either a rotation holding unit that rotates and holds, or a slide holding unit that slides and holds the portable switch. Thereby, if the first switch and the second switch are either a rotation holding unit that is rotated and held, or a slide holding unit that is held by sliding, the operator can operate both hands, Disasters that occur by driving with one hand can be prevented.

  As described above, according to the portable driving apparatus of the present invention, it is possible to prevent a disaster that occurs when the operator performs two-handed driving and the operator performs one-handed driving.

  Hereinafter, an embodiment of a portable operating device according to the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a front view showing a schematic configuration of one embodiment of a portable operating device. FIG. 2 is a block diagram showing device operation control by the portable operation device 1. The portable driving device 1 includes a first switch 2 and a second switch 3 provided in the driving operation unit 10 shown in FIG. 2, and an operation control unit 7 shown in FIG. And the drive device 8 of an apparatus is controlled by the operation control part 7 which received the signal from the 1st switch 2 and the 2nd switch 3. FIG.

  The first switch 2 causes the operator to select an ON / OFF state of device operation and operate it. The second switch 3 causes the operator to select and operate the operation direction (UP / DOWN) of the device.

  Both the first switch 2 and the second switch 3 of the present invention are configured such that the operator cannot hold them simultaneously with one hand. That is, the first switch 2 is normally in an OFF state, and returns to the OFF state if the ON state is not maintained even if the first switch 2 is operated to the ON state. For this reason, the first switch 2 is a so-called spring-back system in which it is returned to the OFF state by a built-in spring. Thereby, even if the operator tries to drive with one hand, the first switch 2 returns to the OFF state, and the driving control unit 7 does not send a driving command to the device. FIG. 1 shows a rotation holding unit 11 that is a method of rotating and holding the first switch 2, but a method of holding the first switch 2 by sliding may be used.

  The second switch 3 is normally in a neutral state, and is configured to return to the neutral state if the state is not maintained even if the second switch 3 is operated by selecting either UP or DOU. Therefore, the second switch 3 is a so-called spring-back method in which the second switch 3 is returned to the neutral state by a built-in spring. Thereby, even if the operator tries to drive with one hand, the second switch 3 returns to the neutral state, and the operation control unit 7 does not send an operation command to the device. Although FIG. 1 shows the slide holding unit 12 that is a method of sliding and holding the second switch 3, a method of rotating and holding it may be used.

  By configuring the first switch 2 and the second switch 3 as described above, the operator does not function unless both the switches 2 and 3 are held with both hands, and one-handed operation is impossible. Can be.

  When the operation control unit 7 receives the ON signal 4 in which the first switch 2 is held in the ON state of the device and the UP signal 5 or the DOWN signal 6 in which the second switch 3 is held in the operation direction of the device, An operation command in the operation direction is transmitted to the device drive device 8. In other words, the operation control unit 7 controls the drive device 8 only while receiving both the ON signal 4 and the UP signal 5 or the DOWN signal 6, that is, while the AND condition is satisfied. An operation command in the operation direction is transmitted.

  Thereby, unless both the first switch 2 and the second switch 3 are held, the AND condition is not satisfied, and the operation control unit 7 does not transmit an operation command to the device. That is, the device is configured not to drive even if the operator tries to drive with one hand.
