Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator which does not require a machine room for installing a control panel.

[0002]

2. Description of the Related Art A machine room for installing a control panel is generally provided at the top of a hoistway. Therefore, maintenance work was performed while moving back and forth between the machine room and the landing. On the other hand, regarding an elevator apparatus which does not require a machine room for installing a control panel, Japanese Unexamined Patent Publication No. Sho 59-163270 discloses an "elevator apparatus". In these proposals, the control panel is stored near a landing on a specific floor. Therefore, when performing maintenance of the control panel, the maintenance staff needs to know the floor where the control panel is installed in advance. In addition, during maintenance and inspection of the equipment in the hoistway, the car has been moved to a position where it is easy to ride on the car by manual operation of maintenance personnel. For example, if the control panel is on the top floor, first lower the car from the top floor to one floor below the top floor by operating the control panel, then open the landing door on the top floor and get on the car. An operator performed the car operation (low speed) on the car and performed an inspection.

[0003]

In the case where a separate machine room for installing a conventional control panel is separately provided, maintenance work is decentralized in the form of a machine room and a landing side, resulting in poor work efficiency. On the other hand, in a configuration in which the control panel is installed near the landing on a specific floor, the degree of freedom in the mounting position of the control panel increases, and the control panel and the landing approach each other. Because there is no floor, the maintenance staff needs to know the floor where the control panel is installed for each building.

In order to carry out the inspection on the car, it is necessary to move the car to an easy-to-ride position. However, if there are non-stop floors, express zones, or uneven floor heights, the car is moved from the top floor by one. Even if you stop on the floor, it is not always easy to get from the top floor. In such a case, the maintenance staff must correct the position while referring to the absolute car position pulse. However, whether or not to bring the car to an appropriate position by this method largely depends on the skill and intuition of the maintenance staff.

Accordingly, an object of the present invention is to provide a maintenance operation device capable of improving the efficiency of maintenance and inspection work by enabling guidance to the floor on which the control panel is installed and smooth transition to inspection on the car. To provide an elevator equipped with:
