Abstract

PURPOSE:To easily execute inspection of power of a battery in a power-off time automatic floor arrival control unit for stopping a cage of an elevator to the nearest floor at the time of power interruption. CONSTITUTION:An inspecting switch 6 is provided, and when it is turned on, a dummy load signal output means 7 converts an in-cage load signal 1a of a load detector 1 into a simulated value of placing the inside of a cage in a heavy load condition. Thus in an operation direction determining means 2, a direction of lowering down the heavier one of a cage and a balance weight is determined as the operation direction, and the cage is lowered down. Thus when the cage is lowered down, power of a battery can be judged sufficient.

2. Description of the Related Art When a car of an elevator is running and a power failure occurs, the car stops, but when the car stops between floors, passengers are trapped in the car. In order to safely and promptly rescue passengers even in such a case, for example, JP-A-60-
An automatic landing device during a power failure is proposed in Japanese Patent No. 228376. This is to drive a car stopped between floors due to a power outage by using a battery as a power source to automatically perform a landing operation to the nearest floor.

Here, measures have been taken to reduce the power consumption for automatic landing at the time of power failure, and to make the battery compact and inexpensive. For example, the car is operated so that the car always operates in the light load direction. That is,
As is well known, an elevator has a car and a counterweight connected to each other via a main rope, and is operated so as to lower one of the heavier ones. For this reason, a load detector is installed in the car to detect the amount of load inside the car and determine if this is 50% or less of the load (maximum load that can be loaded when actually used). If it is 50% or less Go up the car to 5
When it exceeds 0%, it is set to move downward.

However, since the load detector has an error,
Batteries are required to have the ability to run a car even with a heavy load. Therefore, at the time of maintenance, in order to check the capacity of this battery, move the car in the direction of heavy load,
By checking whether the elevator can be operated by maintenance personnel, the power of the battery of the automatic flooring device during a power failure is checked.

However, during normal maintenance and inspection, the inside of the car is unloaded, and in the case where the operating direction is determined by the output of the load detector as described above, the car moves in the ascending direction, so that the direction of heavy load is increased. It cannot be operated and the battery power cannot be checked. Therefore, when checking the battery,
For example, in a load detector of the type in which a contact that makes contact corresponding to the load is provided under the floor of the car, the above contacts are short-circuited so that the load inside the car becomes a heavy load, and the car is loaded in the heavy load direction. That is, it is operating in the descending direction.

SUMMARY OF THE INVENTION In the conventional automatic landing system at the time of power failure as described above, the contacts of the load detector are short-circuited to operate the car in the heavy load direction. There is a problem that the work is time-consuming, and the contacts may be mistakenly connected, and the recovery of the contact short circuit may be forgotten.
