In the conventional hoisting machine for the above-mentioned sluice door, the wire is wound on the cylindrical drum, so that there is a risk of winding disorder, and if this winding disorder occurs. , The tension of the left and right wires that suspend the sluice door is different, and one of the wires is overloaded. Therefore, in this case, the safety device that detects the looseness of the wire and the overload is activated, and the hoisting machine is brought to an emergency stop. Therefore, when the safety device is activated due to such winding disturbance, the door must be lowered once, the winding disturbance is released, and then the door must be pulled up again. It has a problem that it cannot operate. Further, if the safety device does not function sufficiently, there is a possibility that a serious accident such as cutting a wire or breaking a door may be caused.

Further, in this hoisting machine, the wire is gradually wound up into a large diameter while moving to the left and right along the width of the drum. Therefore, the wire is attached to the floor of the machine room building where the hoisting machine is installed. There is a large opening through which the pigeons can easily enter inside, and if left unattended, nests may be built in the machine room, and feces may accumulate in an emergency. Since the device may not function sufficiently, it has to be cleaned and removed regularly, which requires time and labor for maintenance of the device.

The water gate door hoisting machine 1 of the present invention thus constructed is powered on with the motor 2 being turned on with the water gate closed.
Is driven, the rotational force of the motor 2 is transmitted to the left and right output shafts 6, 6 via the speed reducer 5, so that the output shafts 6, 6
The left and right drums 7, 7 fixed to are to be rotationally driven in the same direction to wind up the attached wire 9 and pull up the sluice door 10 suspended by the wire 9. At this time, in the hoisting machine 1 of the present invention, since the drum 7 for winding the wire 9 is the substantially disk-shaped sheave type drum as described above, the wire 9 is not the drum 7.
Without being disturbed along the groove 7b, it is wound up orderly into a single-strip multi-layer winding as shown in FIG. Therefore, the lengths of the wires 9, 9 wound around the left and right drums 7, 7 are always equal, and the sluice door 10 is smoothly pulled up in a state where the wires 9, 9 are evenly loaded.
Further, at the time of this winding, since the wire 9 only moves in the outer peripheral direction of the winding shaft 7a, the floor surface 13 of the machine room 13
The wire insertion opening 13b formed in a has a slit-like narrow width and sufficiently performs its function. The area of the opening 13b is significantly smaller than that of the conventional one.

Further, as described above, in the hoisting machine 1 of the present invention, since the wire 7 is wound in a single-layer multi-layer winding, when the drum 7 is driven at a constant rotation, the winding length of the wire 9 is initially set. Is short, and gradually increases as the winding diameter increases. This means that the maximum driving force is exerted in the initial stage of opening when the water pressure is applied to the sluice gate 10, and the opening speed is improved in the final stage of the opening, so that the sluice door 10 can be driven to open sensiblely. .
When the sluice door 10 is pulled up to a predetermined position in this way, the motor 2 is stopped by the action of a limit switch, a sensor, and the like (not shown), and the suspension device 21 engages with the door 10, thereby 10 is held in an open state.

In this embodiment, an example using one hoisting machine is shown, but a plurality of hoisting machines using similar sheave type drums may be used to open and close the sluice door. Well, in the embodiment, an example is shown in which the other end of the wire, one end of which is fixed to the drum, is immovably fixed to the lower side of the hoisting machine. You may wind up at the same time with the winding machine attached. Furthermore,
In the embodiment, the pulley on which the wire is hung is one example, but if at least one end of the wire is wound by a sheave-shaped drum, a plurality of pulleys are used to drive the sluice door up and down. It may be the one that has been done.

As described above, in the sluice door hoisting machine of the present invention, since the wire for pulling up the sluice door is regularly wound into a single-layer multi-layer winding by using a sheave-shaped drum, troubles caused by winding disorder are caused. By avoiding this, the sluice gate will be opened and closed reliably, and the reliability of the sluice gate used in an emergency such as a flood will be improved. In addition, since the winding speed is slow in the initial stage of opening the door and fast in the final stage, sufficient driving force can be obtained when water pressure is applied, the time required for opening and closing can be shortened, and quick response can be made in an emergency. It Furthermore, since the opening through which the wire hanging the sluice door is inserted is narrow,
It has many excellent effects that it is difficult for a pigeon or the like to enter the machine room, and labor and time required for maintenance of the device are reduced.
