(57) [Summary] [Purpose] To provide a flood car damage prevention device for an elevator car that can prevent water from flowing in from above the car. A water drop blocking device is provided on the upper beam 2 of the car frame 3 for unwinding and rolling in a waterproof sheet 6 covering a maintenance operation device 9, a door driving device 10 and the like, which are arranged above the car room 4 when the elevator is flooded. Provided.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a flood car damage prevention device for an elevator car.

[0002]

[Prior art]

 As a conventional flood damage prevention device for an elevator, as described in Japanese Utility Model Publication No. 62-89269 or Japanese Utility Model Publication No. 56-112176, the information from the water sensor is taken in, and the elevator car It has been proposed to try to evacuate to a position that avoids flood damage.

[0003]

[Problems to be solved by the device]

 By the way, depending on the environment in which the elevator is installed, a large amount of water may flow into the hoistway from the elevator hall on the upper floors of the building during heavy rain, and the upper part of the car may become wet.

However, the above-described technique has a problem in that the car is exposed to water from above, and consideration is not enough to prevent a failure that may occur in a maintenance operation device, a door drive device, or the like attached to the upper part of the cab. there were.

An object of the present invention is to provide a flood damage prevention device for an elevator car that can prevent water from flowing in from above the car.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention relates to an elevator car flood damage prevention device provided in an elevator in which a car room is placed on a car frame having an upper beam suspended from a rope. A water drop blocking device having an unwinding and rolling up type waterproof sheet covering the upper part of the car room is attached, a water sensor is installed on the upper beam, and the waterproof sheet of the water drop blocking device is wound by a signal from the water sensor. It was made to be rolled up.

[0007]

[Action]

 According to this invention, the waterproof sheet unwound in response to the signal from the water sensor provided on the upper beam directly covers the upper part of the cab, so that the maintenance installed on the upper part of the cab is performed. The effect of preventing flood damage to equipment such as operating devices is great.

[0008]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. 1, 2 and 3. 1 is a sketch of an elevator car, FIG. 2 is a flow chart of the apparatus, and FIG. 3 is a circuit diagram.

In the figure, 1 is a rope, 2 is an upper beam suspended from the rope 1, 3 is a car frame that is integral with the upper beam 2, 4 is a car room placed on the car frame 3, and 5 is a car room. A water drop blocking device 7 for unwinding and rolling in the waterproof sheet 6 supported by the upper beam 2 is provided on the upper beam 2, and a water sensor of a type in which an operation signal is emitted when the water beam is continuously received and no signal is generated when the water beam is interrupted. Sensor, 8 is a lower guide that guides the lower side of the waterproof sheet 6 at the time of unwinding and rolling, 8'is an upper guide, 9 is a maintenance operation device mounted on the upper part of the car room 4, and 10 is also a car room. 4 is a door driving device.

That is, when the water sensor 7 provided on the upper beam 2 continues to receive water droplets, an unwinding signal is issued to the water droplet blocking device 5 to unwind the waterproof sheet 6 along the lower guide 8 and the upper guide 8 '. When there is a break, there is no signal and the water drop blocking device 5 winds up the unwound waterproof sheet 6.

This will be described with reference to a flow chart and a circuit. The contact point a of the water sensor 7 is turned on by the operation signal of the water sensor 7, and P-7a-R ₁ -N is closed, whereby P-R ₁ a- The self-holding circuit P-Da-D LS-D-N is closed from the P-R ₂ a-DLS-D-N by the T ₁ b-R ₂ -N, and the output detection switch is opened by the P-Da-Down-N. The unwinding command of the waterproof sheet 6 is issued until the DLS is opened.

[0012] At the same time, each of the timer is started _{P-R 2 a-T 1} -N, the _{P-R 2 a-T 2} -N. T ₁ is a timer that starts counting after a fixed time, and T ₂ is a timer that ends counting after a fixed time. Upon detection of a predetermined time by a timer, to open the _{P -R 2 a-T 1 b} -R 2 -N, thereby _{P-R 2 a-T 1} -N, also P-R ₂ a -T ₂ -N When the water sensor 7 is opened and a water drop is received at this point, the timer is reset as described above.

Further, when the water sensor 7 has no signal, the self-holding circuit T-Ua-T ₂ b-ULS-N is closed from P-R ₁ b-T ₂ b-ULS-UN and P-R ₁ b-T ₂ b-ULS-UN is closed. -Ua-UP-N issues a command to enclose the waterproof sheet 6 until the entrainment limit detection switch ULS is opened.

[0014]

[Effect of device]

 According to this invention, the waterproof sheet unwound in response to the signal from the water sensor provided on the upper beam directly covers the upper part of the cab, so that the maintenance installed on the upper part of the cab is performed. The effect of preventing flood damage to equipment such as operating devices is great.
