Technical field

The present invention relates to an elevator apparatus having a car whose elevation is controlled by a control panel. Background art

2. Description of the Related Art Conventionally, in a traction-type elevator system that raises and lowers a hoistway by pulling a car with a hoisting rope, a machine room is provided outside the hoistway such as a rooftop. This machine room is equipped with a hoist that hoists the hoisting rope, a control panel that is electrically connected to the hoist, etc., and controls the elevating of the car. Then, when performing maintenance and inspection of the elevator, the operator enters the machine room and performs predetermined work.

On the other hand, there is known an elevator device that can save space by providing a hoisting machine integrated with a control panel at the top of a hoistway without having a machine room outside the hoistway. (See, for example, Japanese Patent Application Laid-Open No. Hei 7-010304).

However, such a known elevator apparatus has a problem in that the efficiency of work is low when performing maintenance and inspection of a control panel. In other words, the worker first gets on the top of the car from the landing outside the hoistway to maintain and inspect the control panel located at the top of the hoistway. Then, with the worker sitting on the top of the car, move the car to near the top of the hoistway and stop at that position. Thereafter, the worker performs a predetermined operation at that position.

In particular, when self-propelled operation is not possible (even when self-propelled operation is not possible), the operator must move the car by lifting the brakes of the hoist while the operator is on the top of the car. However, the workability of the worker on the car cannot be secured.

Therefore, the present invention solves such a problem of the conventional elevator apparatus, and is an elevator apparatus capable of saving space without having a machine room outside a hoistway. It is an object of the present invention to provide an elevator system with high work efficiency for panel maintenance and inspection. Disclosure of the invention

The present invention is designed to reduce the lower end of the control panel of the elevator system so that when a worker gets into the upper part of the car from a landing outside the hoistway, maintenance and inspection can be performed at that position. It is arranged so that it substantially matches. As a result, the operator does not need to move from the car to the control panel maintenance position to perform maintenance and inspection of the control panel, and can easily and efficiently work.

According to the present invention, the control panel of the improved elevator apparatus described above is supported on a guide rail or a wall surface. As a result, the operator does not need to move from the car to the control panel maintenance position to perform maintenance and inspection of the control panel, and can easily and efficiently work.

In addition, the present invention provides a method for controlling the lower surface of a car upper surface when the operator moves the lower end of the control panel of the above-described improved elevator system to a position where the operator can easily get into the upper part of the car from the landing. It is arranged so as to substantially coincide with the position. As a result, the operator can get on the upper part of the car and perform the maintenance and inspection of the control panel reliably at that position.

Further, according to the present invention, the car is moved from the lower end of the maintenance area operated by the maintenance and inspection of the control panel of the improved elevator device to a position where the operator can easily get into the upper part of the car from the landing. It is arranged so that it is above the position of the upper surface of the car at the time. As a result, the operator can get on the upper part of the car and perform the maintenance and inspection of the control panel reliably at that position. BRIEF DESCRIPTION OF THE FIGURES

Here, the control panel 5 is supported by the support member 3 a on the guide rail 3 so as not to interfere with the car 2. More specifically, the control panel 5 has a guide rail such that its lower end 5a is at the same height as the landing 6 on one floor (for example, the top floor) of the passenger landings provided on a plurality of floors. Supported by three.

The car 2 has a car upper part 2a, and the workers 7a and 7b can get into the car upper part 2a from the above-mentioned passenger hall.

In the elevator apparatus configured as described above, maintenance and inspection of the control panel 5 are performed according to the following procedure. That is, the workers 7a and 7b must first maintain the upper car 2a of the car 2 in order to maintain and inspect the control panel 5 located near the landing 6 on the predetermined floor in the hoistway. The car 2 is moved so that it almost matches the height of the landing 6 of the car. Here, the movement of the car 2 is performed by operating a compulsory car moving means operable from outside the hoistway. In particular, when the control panel 5 breaks down or a power outage occurs and the car 2 cannot run on its own, the car 2 is moved by means such as releasing the brake of the hoist. Next, the workers 7a and 7b get into the car upper part 2a of the car 2 from the landing 6. At this time, the control panel 5 is arranged such that the lower end 5a thereof substantially coincides with the position of the car upper part 2a. That is, the control panel 5 is arranged within the reach of the workers 7a and 7b. Thus, the workers 7a and 7b perform predetermined work on the control panel 5 at the positions.
