Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator automatic car position adjusting device having an automatic car position adjusting function at the time of maintenance and inspection, and a maintenance and inspection method.

[0002]

2. Description of the Related Art A conventional elevator is constructed, for example, as shown in FIG. In FIG. 4, reference numeral 1 denotes a hoistway provided through each floor of the building. An elevator car 2 is provided in the hoistway 1 so as to be vertically movable. One end of a rope 3 is connected to the car 2, and a counterweight 4 for balancing the weight with the car 2 is connected to the other end of the rope 3 via the rope 3.

A motor 5 is provided in the machine room 6 and drives the car 2 up and down. The motor 5 has a rotating shaft (not shown) on which a rope 3 is hung above the car 2. Sheave 7 is attached. A sheave 8 on which the rope 3 is hung is also rotatably supported above the counterweight 4. In FIG. 4, floors, hatch doors and the like of each floor are not shown.

The elevator car 2 moves up and down to a target landing floor while being weight-balanced with the counterweight 4 via the drive sheave 7, the sheave 8 and the rope 3 by the drive of the motor 5.

At this time, the drive control of the motor 5 is performed by detecting speed detection information from a speed detector (for example, a pulse encoder not shown) attached to the drive shaft of the motor 5 and a load weight detector (shown in FIG. The controller (for example, a computer) (not shown) is configured to perform the operation based on the loaded weight detection information or the like from a load sensor (for example, omitted).

[0006] In the elevator configured as described above, maintenance and inspection personnel need to ride on the car, that is, on the ceiling of the car 2 during maintenance and inspection of the elevator. Conventionally, as a procedure for getting on the car, first, for example, a maintenance and inspection staff pushes a floor designation button in the car 2 of the elevator stopped at the normal stop position on the first floor as shown in FIG. Move to floor level.

After a predetermined time, the hatch door 10 is manually forcibly opened to stop the moving car 2 in an emergency. As a result, the maintenance and inspection staff gets into the ceiling of the car 2 stopped at the position as shown in FIG. 5B and starts the maintenance and inspection work.

FIG. 5 schematically shows the relationship between the main part of the elevator constructed as shown in FIG. 4 and the hatch door 10 provided on the first floor.

[0009]

In adjusting the position of the car at the time of maintenance and inspection of the elevator as described above, the car 2 is moved to one position.
The timing (time) for opening the hatch door 10 and stopping the car 2 after moving from the floor to the basement floor depends on the experience of the maintenance and inspection staff and the can. For this reason, the stop position of the car 2 is a position where the maintenance and inspection staff can easily get on the ceiling of the car 2 safely, that is, as shown in FIG. 5B, the ceiling position of the car 2 is substantially the same as the floor position of the first floor. It doesn't always stop.

Therefore, if the timing of opening the hatch door 10 is too early, for example, as shown in FIG. 5 (c), the ceiling of the car 2 stops at a position much higher than the floor level, and the timing of opening the hatch door is delayed. If it is too late, as shown in FIG. 5D, the ceiling of the car 2 stops at a position much lower than the floor position.

In the case of FIG. 5 (c), the gap is too narrow to allow the maintenance and inspection personnel to get on the ceiling of the car 2, or even when the person can get on, he must climb up the ceiling from the narrowed gap. It is very labor intensive and not safe.

In the case of FIG. 5D, since the ceiling position of the car 2 is considerably lower than the floor height, it is impossible to get on the ceiling, or the maintenance and inspection personnel need to take the car 2 from the floor.
It is very dangerous to jump down to the ceiling and move.

Further, as shown in FIGS. 5C and 5D, when the car 2 stops at a position where safety is impaired, the car 2 is stopped at the optimum position as shown in FIG. 5B. 5C and 5D, the hatch door is closed once, the car 2 is recalled to the first floor by the call button, and the operation described in FIG. 5A must be repeated. Operation is cumbersome.

Even if the above operation is tried again, the timing of opening the hatch door 10 and stopping the car 2 depends on the experience of the maintenance and inspection staff and the can. ), It is not always possible to stop at the optimum position. For this reason, the above operation must be repeated three or more times, and the start of the maintenance and inspection work is greatly delayed.

As described above, the conventional elevator car position adjustment and maintenance / inspection method is not only capable of reducing safety when the height difference between the elevator car and the floor is too large, but also stopping the elevator at a safe and optimum car position. There is a problem that it takes a lot of time.

The present invention has been made in view of the above points, and an object of the present invention is to adjust the position of a car to a position where a maintenance and inspection staff can easily and safely get on the car with a simple configuration.
