Description

The present invention is most suitable for safety when the elevator maintenance operation device, particularly when at least two installation workers and maintenance personnel perform installation and maintenance work in a car or in a machine room and a so-called pit at the bottom of a hoistway. The present invention relates to an elevator maintenance operation device.

In the elevator pit, safety devices and various other devices necessary for safe operation of the elevator are installed. In order to confirm that these devices and equipment operate normally, confirmation work upon completion of installation by an elevator installation worker and periodic inspection work by maintenance personnel are performed on these devices and equipment.

This confirmation work and inspection work are usually carried out by one person as in Patent Document 1.

Here, the prior art according to Patent Document 1 will be described with reference to FIGS. The installation worker and maintenance staff will be described as maintenance staff. A machine room 2 is provided above the hoistway 1, and a control device 6 is installed in the machine room 2. The car 3 is connected to the driving machine 4 via the rope 5, and the driving machine 4 is controlled and driven by the control device 6. In addition, 8 is a landing floor and 9 is a landing door.

Driving operation panels D1 and D2 are provided in the car 3 and on the car 3, and the car 3 can be lifted and lowered by these driving operation panels D1 and D2. The transmission line 12 having one end connected to the control device 6 is guided along the side wall in the hoistway 1 to the elevating bottom portion, so-called pit 7, and the other end is connected to the plug receiver 11 provided in the pit 7.

Maintenance personnel 14 in the pit 7 can mount the portable operating device 13 on the plug receiver 11 and operate the car 3 with the operating device 13. With the operation device 13 mounted on the plug receiver 11, the operation of the operation control panels D1 and D2 is blocked by the blocking circuit.

As shown in FIG. 7, a cable 15 is attached to the operating device 13, and a plug 31 is fixed to the end of the cable 15, and the operating device 13 is attached to the plug receiver 11 by the plug 31. The operation device 13 is provided with an emergency stop switch 13a, an ascending operation button 13b, and a descending operation button 13c.

As described above, the maintenance staff 14 and the like in the invention according to Patent Document 1 can operate the car 3 while in the pit even if it is a single work. Even if a third party operates the controllers D1 and D2 on the car without noticing that there is a maintenance person 14 in the pit 7, the elevator does not drive and the maintenance person 14 Safety is ensured.

The confirmation work and the inspection work are generally carried out by one person as in Patent Document 1, but there are cases where two or more people have to work by necessity.

If the maintenance operation device according to the invention of Patent Document 1 is used, it is possible for a maintenance person or the like in the pit to drive the elevator alone, but depending on the work contents, it is necessary to check various devices in the driving state. In spite of this, both hands are blocked by the operation of the maintenance operation device, and there are cases where it is difficult to perform the confirmation work.

Basically, when these maintenance personnel are present in the pit, the driving of the elevator is prohibited. However, there are cases where it is necessary to drive the elevator in a state where maintenance personnel or the like are in the pit in response to various confirmation tasks during installation or troubles during maintenance.

For example, when an elevator is driven in a state where maintenance personnel are in the pit during installation, there are confirmation of control operation, confirmation of car balance, confirmation of guide shoes, and the like. In addition, when the elevator is driven in a state where maintenance personnel or the like are in the pit for maintenance, there are brake adjustment and machine noise check.

JP-A-62-111883

As described above, there may be a case where two or more people are out of tasks that cannot be confirmed unless the elevator is driven. In this case, one maintenance worker in the car or on the car operates the elevator according to the instruction of the other maintenance worker in the pit. Then, while the elevator is being driven, the other maintenance staff or the like performs an operation such as confirmation in the pit. Maintenance personnel in the pit recognize that the elevator is driving as instructed, and secure a safe place and posture. In this case, communication between maintenance personnel and the like is important for safety. This is because when the elevator performs an operation different from the instruction of the maintenance staff in the pit, the maintenance staff in the pit is surprised and it is difficult to ensure safety. Further, in the prior art, confirmation work has been performed by calling or talking by a transceiver. For this reason, high-speed operation is possible despite driving at the opposite direction or instructing low-speed operation due to the on-site environment, operation mistakes, instruction mistakes, assumptions of car maintenance personnel, etc. and transceiver failures. There were not a few cases where elevators performed unintentional actions such as, causing dangerous situations that could lead to accidents.

The problem to be solved by the present invention is to avoid dangerous work situations as described above and to ensure the safety of maintenance personnel in the pit.

The elevator is controlled in the hoistway by the control device, and is provided in the car and on the car, and is connected to the operation control panel for performing the raising and lowering operation of the car, one end connected to the control device, and the other end In an elevator having a transmission line led to the bottom of the hoistway, a removable operation device is provided at the other end of the transmission line, and the previous operation device is a driving operation panel in the car and on the car. It has a button which gives permission by pushing down the raising / lowering operation operated on the driving operation panel, and the elevator is not driven unless the permission is given by the button.

According to the present invention, the maintenance staff in the pit confirms the operation contents operated by the maintenance staff in the car, and the elevator does not drive unless permission is given. Therefore, the safety of the maintenance staff in the pit is ensured. Can work safely.
