Problems solved by technology

This deflection reinforces the entrance sill 113, thereby ensuring the installation size, but it is difficult to confirm how deep the docking detection plate 122 bites into the docking detector 121 on each floor.
In addition, when an earthquake occurs, there is a problem that when the elevator stops, since the stop detector 121 is arranged at the lower part of the elevator car 108, it cannot be visually confirmed from above the elevator car 108. The phenomenon that the stop detector 121 cannot be adjusted without going to the elevator pit, and the degree of engagement with the stop detector plate 122 cannot be confirmed even if the stop detector 121 is adjusted

Abstract

The invention provides an elevator device which provides convenience for maintenance such as detecting of stop detection devices, i.e., a stop detection device and a stop detection plate and confirmation of the quantity of nipping of the stop detection plate by the stop detection device. The elevator device of the invention comprises the stop detection devices which comprise a plurality of stop detection devices (21) with optical axis sensors composed of light emitting portions (E) emitting light and light receiving portions and a detection plate (22) sheltering light of the stop detection devices (21). Floor level information used for adjusting the difference between a floor of an elevator hall and a floor of an elevator car to be within a prescribed scope is recorded on the detection plate (22). The stop detection devices (21) are arranged on the upper portion of an elevator car door opening and closing mechanism in the elevator car (8), and the detection plate (22) is arranged on the upper portion of an elevator hall door opening and closing mechanism in each elevator hall.

Description

technical field [0001] The invention relates to an elevator device, in particular to an elevator device provided with a stop detection device. Background technique [0002] Generally, an elevator device is composed of an elevator car, a counterweight, a main sling, a balance cable, a tail cable, and the like. In addition, a stop detection device is provided in order to detect a stop position at which the elevator car stops on each floor. In the parking detection device, a parking detector equipped with a light-emitting part for outputting light and a light-receiving part for receiving light is provided on the side of the elevator car, and a detection plate (hereinafter referred to as The parking detection plate.) is installed on the side of the hoistway, and the parking detection plate blocks the light output from the parking detector, thereby performing position detection (stopping detection) of the elevator car. [0003] In an elevator apparatus including such a stop det...
