Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator maintenance operation device.

[0002]

2. Description of the Related Art Safety devices and other various devices and equipment required for safe operation of an elevator are installed on an elevator shaft. In order to confirm that these equipments operate normally, regular inspections are performed by maintenance personnel. This inspection usually requires two maintenance personnel. For example, one of the maintenance personnel riding in the elevator car operates the elevator using a driving operation panel installed inside the car. In the pit, the other maintenance staff works on equipment installed in the hoistway or in the car while the car is moving or stopped. However, the conventional inspection method requiring maintenance personnel only for the operation of the car is not desirable because the maintenance cost increases. As one means for solving the drawbacks of the conventional inspection method, Japanese Laid-Open Utility Model Publication No. Sho 50-136160 proposes this kind of elevator maintenance operation device. With the proposed means, inspection of various devices and devices installed in the hoistway other than the pits can all be performed by one maintenance person.

[0003]

In the above prior art, when checking various devices and equipment in the pit, two maintenance personnel are still required. That is, one of the maintenance personnel needs to enter the pit and inspect various devices and equipment, and the other maintenance personnel need to get into the car and operate the elevator. In addition, when the maintenance staff separates and works in the pit and the elevator car in this way, there is a risk of a disaster when mutual communication is insufficient. SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator maintenance and operation device in which one maintenance person in the pit can inspect the pit device and equipment and operate the elevator car safely.

[0004]

SUMMARY OF THE INVENTION The object of the present invention is to provide a control device provided in a machine room for controlling a hoistway in a hoistway having a pit at the bottom and a car provided inside and above the car. In an elevator maintenance operation device comprising an operation operation panel for performing a lifting operation, the operation operation panel provided on the car includes a cord length adjustment device,
This is achieved by having a driving operation panel operable in the pit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. FIG. 1 shows an overall configuration of an elevator using an elevator maintenance operation device according to the present invention. A machine room 2 is provided above a hoistway 1, and a control device 5 is installed in the machine room 2. The car 3 is connected to the driving machine 4 via a rope 6, and the driving of the driving machine 4 is controlled by a control device 5. Operation control panels 7a and 7b are provided inside the car 3 and on the car 3, and the operation control panels 7a and 7b enable the car 3 to be raised and lowered. Further, below the car 3, an operation control panel 7c
The maintenance personnel 9 in the pit 8 can operate the car 3 by the operation control panel 7c.
As shown in FIG. 2, an emergency stop switch 71, an ascending operation button 72, and a descending operation button 73 are attached to the operation control panel 7c.

When inspecting the inside of the pit 8 of the elevator, the maintenance person 9 operates the car 3 by the operation control panel 7a in the car 3.
From the bottom floor to the level where it can enter the pit 8. Next, the passenger gets off the car 3 and enters the pit 8. At this time, the operation control panel 7c provided below the car 3 is dropped into the pit 8. In the pit 8, the maintenance staff 9 lowers or raises the car 3 by the operation control panel 7c, checks the safety devices and other various devices and devices installed in the pit 8, and confirms the operation. After the inspection is completed, the maintenance person 9 raises the car 3 to a position where the car 3 can exit the pit 8 by the operation control panel 7c.
When exiting the pit 8, the operation control panel 7c is returned to a predetermined position below the car 3. After getting out of the pit 8, the elevator is returned to normal by the operation operation panel 7a in the car 3.

Next, another embodiment of the present invention will be described with reference to FIGS.
This will be described below. FIG. 3 shows an overall configuration of an elevator using the elevator maintenance operation device according to the present invention. A machine room 2 is provided above a hoistway 1, and a control device 5 is installed in the machine room 2. The car 3 is connected to the driving machine 4 via a rope 6, and the driving of the driving machine 4 is controlled by a control device 5. An operation control panel 7a is provided inside the car 3, and the operation control panel 7a allows the car 3 to be raised and lowered. Further, on the car 3, an operation control panel 7d is provided via a cord length adjusting device 10 such as a drum, and a maintenance person 9 in the pit 8 operates the operation control panel 7d.
Thus, the car 3 can be operated. As shown in FIG. 2, an emergency stop switch 71, an ascending operation button 72, and a descending operation button 73 are attached to the operation control panel 7d.

When inspecting the inside of the pit 8 of the elevator, the maintenance person 9 operates the car 3 by the operation control panel 7a in the car 3.
From the bottom floor to the level where it can enter the pit 8. Next, the passenger gets off the car 3 and enters the pit 8. At this time, the operation control panel 7d detachably provided at the lower part of the car 3 is dropped into the pit 8. In the pit 8, the maintenance staff 9 lowers or raises the car 3 by the operation control panel 7d, and inspects safety devices and other various devices and devices installed in the pit 8,
Check the operation. After the inspection is completed, the maintenance person 9 raises the car 3 to a position where the car 3 can exit the pit 8 by the operation control panel 7c. When exiting the pit 8, the operation control panel 7d is returned to a predetermined position below the car 3. After exiting pit 8,
The elevator is returned to normal by the operation control panel 7a in the car 3.

When operating on the car 3, the operation control panel 7d is pulled up and used.

According to the present embodiment, the car 3 in the pit 8
Operation is possible. Thus, the maintenance person who performs the inspection in the pit can drive the car, so that the inspection work can be performed by one person. Moreover, since the maintenance staff in the pit operates the car itself, there is an effect that the work can be performed safely without fear of a disaster when mutual communication is insufficient such as when two people work.

[0011]

According to the present invention, it is possible to operate the car 3 in the pit 8. As a result, the maintenance staff who performs inspections in the pit can drive the car,
Inspection work by one person becomes possible. Moreover, since the maintenance staff in the pit operates the car itself, there is an effect that the work can be performed safely without fear of a disaster when mutual communication is insufficient such as when two people work.
