At this time, the pin gear in the other drive unit 8 connected to the drive unit 7 via the relay shaft 9 is also driven to rotate in the same direction, and the rack member 1 meshed with the pin gear is similarly pulled up. Therefore, the door body 3 suspended by the pair of left and right rack members 1 and 1 is pulled upward to open the water gate.

うに駆動装置７を再起動させれば良い。At this time, all the loads of the driving devices 7, 8 and the rack member 1 and the door 2 are applied to the lower ends of the driving devices 7, 8, but the driving devices 7, 8 are as described above. Since one end thereof is pivotally connected, a force acts in a direction of rotating counterclockwise in FIG. Accordingly, a compressive force acts on the load cell 6, and this load value is input to a control device (not shown) as an electric signal,
The information is displayed on the monitor unit (not shown). If this value is equal to or greater than a preset value, the control device determines that there is an abnormality, stops energizing the drive device 7, and stops driving the door body 2. Therefore, in this case, it is only necessary to remove driftwood or the like that is preventing the door body 2 from rising by rotating the motor in the reverse direction, and then restart the driving device 7 so that the operation continues.

Even when the door 2 is lowered, the load of the door is applied to the driving devices 7 and 8. However, if the lowering of the door 2 is unreasonable due to the bite of driftwood or the like, the rack member 1 is used. A force in the direction of being pushed up acts on the driving devices 7 and 8,
A tensile force is generated in the load cell 6 on the other side of the driving devices 7, 8 having one end pivotally connected. Therefore, also in this case, the control device determines that there is an abnormality, and stops the door 2 at that position. Just start it.

However, in the present invention, the rotational moment applied to the driving device is controlled by the load cell 6. The gist is that the load during driving of the door 2 can be monitored by measuring, and a load cell is similarly provided in a wire rope type using a hoist as a driving device. Is also good. In this case, only an abnormality when the door is lifted is sensed.
