Problems solved by technology

[0004] In the above-mentioned conventional operation method during an earthquake, since the test operation of the car is performed at a lower speed than normal operation, the inspection time is long in the elevator with a long lifting stroke.
In addition, when it is necessary to automatically detect whether there is any abnormality in the elevator based on the noise or vibration generated in the hoistway during the test operation, some abnormalities (machine vibration, etc.) cannot be detected only in low-speed operation.

Embodiment approach 1

[0012] Fig. 1 is a block diagram showing an elevator apparatus according to Embodiment 1 of the present invention. In the drawing, a driving device (hoist) 1 is provided on the upper part of the hoistway. The drive device 1 has a drive pulley 2 and a drive device main body 3 . The driving device main body 3 has a motor unit that rotates the driving pulley 2 and a braking unit that brakes the rotation of the driving pulley 2 .

[0013] In the vicinity of the drive device 1 there are deflector wheels 4 . A plurality of (only one is shown in the figure) main ropes 5 are wound around the drive pulley 2 and the deflection pulley 4 . The main cable 5 has first and second end portions 5a, 5b. The car 6 is connected to the first end portion 5 a of the main rope 5 . A counterweight 7 is connected to the second end portion 5 b of the main cable 5 . That is, the car 6 and the counterweight 7 are suspended in the hoistway by the main rope 5, and are raised and lowered in the hoistway...

Abstract

The invention provides an automatic inspection method of an elevator device and an elevator control device. An object of the present invention is to obtain an automatic inspection method and an elevator control device for an elevator apparatus capable of efficiently performing an automatic inspection operation after a car is stopped due to a disaster. As a solution, the inspection operation part (9) from the inspection operation start position to the first return position, after carrying out the inspection under the extremely low speed operation in the direction away from the car 6 and the counterweight 7, from the first return position The inspection is performed at a low speed at the start position of the inspection operation, and then the inspection is performed at a very low speed up to the second return position, and then the inspection is performed at a low speed from the second return position to the start position of the inspection operation. Check.

Description

technical field [0001] The present invention relates to an automatic inspection method of an elevator apparatus for performing an inspection operation on a car stopped due to a disaster such as an earthquake, and an elevator control device having an inspection operation function. Background technique [0002] In the conventional method of operating an elevator during an earthquake, when a predetermined time has elapsed since the car stopped due to an earthquake, a test run is performed with no one in the car, and then normal operation is resumed. In the test operation, the car is operated at a lower speed than normal operation, and the car is stopped at each floor to open and close the doors (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese Patent Laid-Open No. 60-171980 [0004] In the above-mentioned conventional operation method during an earthquake, since the test operation of the car is performed at a lower speed than normal operation, the...
