Description

  The present invention relates to an elevator landing apparatus.

Conventionally, in an elevator for observation, the hoistway temperature is remarkably increased due to the weather, season, sunshine duration, etc., or the guide rail becomes hot due to the influence of direct sunlight, and the phenomenon of extending in the longitudinal direction occurs. The phenomenon that the guide rail extends is more prominent as the ascending / descending stroke is larger, and is accumulated more as the level is higher. In particular, in a flexible structure building, the guide rail is made of a sliding clip (the clip is made of spring steel and is strong in the longitudinal direction of the rail to prevent the distortion in the longitudinal direction of the guide rail of the building from being transmitted to the guide rail. It is attached with something that slides away when a large force is applied. On the other hand, the detection plate for the landing device is fixed to the guide rail with a fixing clip.
A conventional elevator landing apparatus will be described with reference to FIGS. 11 is a plan view of the hoistway, FIG. 12 is a longitudinal sectional view showing a part of the hoistway, FIG. 13 is an enlarged front view showing a guide rail mounting portion and a landing plate detection plate mounting portion, and FIG. 14 is an enlarged perspective view of part A in FIG. 13, and FIG. 15 is an enlarged perspective view of part B in FIG. 1 is a building beam such as a large building floor beam, 11 is an intermediate beam provided between the building beams 1, 8 is an elevator car placed in the hoistway, 16 is a counterweight placed in the hoistway, 4 is a guide rail erected on the hoistway wall, 5 is a spring steel sliding clip for attaching the guide rail 4 to the building beam 1 or the intermediate beam 11 via the rail bracket 13, and has a strong vertical force. Can be slid to escape. Reference numeral 14 denotes a detection plate mounting arm that is firmly fixed to the guide rail 4 by a fixing clip 15, and 6 denotes a detection plate that is a detected object for the landing device attached to the detection plate mounting arm 14.
Further, as a conventional technique, there is known one that can easily install and adjust an elevator car position detector and confirm an operation, and can be installed in a narrow hoistway (see, for example, Patent Document 1). .

  However, in the conventional elevator landing device, the detection plate, which is the detection object for the landing device, is fixed to the guide rail with a fixing clip, so that the guide rail is stretched due to the temperature rise in the hoistway. In this case, the detection plate for the landing device fixed to the guide rail also moves together with the extension of the guide rail. For this reason, an elevator landing error occurs, and passengers have to pay attention to their feet when getting on and off.

  The present invention has been made to solve the above-described problems. An elevator landing apparatus having a structure in which a detection object for a landing apparatus is attached to a building beam or an intermediate beam without being attached to a guide rail. Is intended to provide.

  The elevator landing device according to the present invention comprises a landing device detector main body installed on the elevator car side, and a landing device detected object installed on the hoistway side, and the engagement between them. With the guide rail that is installed in the hoistway so that it can be slid and escaped when a strong force in the vertical direction works, without attaching to the guide rail, And a detection object for a landing device attached to a building beam or an intermediate beam of a hoistway.

  According to the present invention, even if the guide rail extends due to the influence of temperature rise due to direct sunlight hitting the hoistway, the vertical shift between the hoistway side and the guide rail is slid and absorbed, and is detected for the landing device. Since the body is fixed to the building frame side of the hoistway, it is independent of the guide rail and can maintain the normal landing position without being affected by the extension of the guide rail. There is no problem with the steps.
