Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seismic control operation device for an elevator that performs seismic control operation when an earthquake exceeding a predetermined level occurs.

[0002]

2. Description of the Related Art Generally, in an elevator, in order to minimize damage to the elevator itself and its accessories when an earthquake occurs, measures such as strengthening the seismic resistance of the elevator components and various related equipment are taken. It has been subjected.

Further, as described in, for example, Japanese Patent Laid-Open No. 51-14645, the safety of passengers in a car is ensured when an earthquake occurs, and an unexpected accident caused by a serious deterioration in function of an elevator occurs. In order to prevent this, an elevator seismic control operation device that performs seismic control operation has been proposed. In this seismic control operation device, when the seismic detector detects an earthquake, stop the car at the nearest floor and then stop elevator operation to prevent secondary damage to each equipment. It has become.

A conventional seismic control operation device of this kind operates with an extra-low sensor operating with a relatively small vibration exceeding a first level, and with a vibration exceeding a second level above the first level. And a seismic control operation circuit that performs control operation according to the seismic detection signals output from these seismic detectors. The extra low detector and the low detector are built in an earthquake detector box installed in an elevator machine room or a pit, for example, a height of 6
When the elevator is installed in a building of 0 m or less, the first level (that is, the sensing level of the extra low sensor) is set to 80 Gal, and the second level (that is, the sensing level of the low sensor) is set to 80 Gal. Is set to 120 Gal, and the extra low sensor is automatically returned by the automatic return coil after the operation, while the low sensor is manually returned after the operation.

Further, when the above-mentioned low sensor operates due to the occurrence of an earthquake of a level exceeding 120 Gal, a technician of an elevator maintenance company inspects the elevator and damages the normal operation. After confirming that it is safe enough, the low sensor is manually restored. Therefore, since the elevator is suspended so that it cannot be used until it is confirmed that the elevator is sufficiently safe, the secondary disaster associated with the earthquake can be minimized.

Further, in recent microcomputer-controlled elevators, control of the car running state, door opening / closing control, and seismic control operation control at the time of an earthquake are programmed, and in addition, various standard specifications are available as standard specifications. If so, the control program of that specification is already built in. Therefore, by inputting a signal from the external sensor of the corresponding additional specification, the control program of the specification can be used. Therefore, for example, when adding the specification of seismic control operation, an earthquake detector is installed in the elevator machine room, and the signal of the contact point that closes when the earthquake detector operates is determined by a predetermined terminal of the input interface section of the elevator controller. It is designed to connect to.

Further, in recent microcomputer-controlled elevators, the operating state of the elevators is constantly monitored for 24 hours, that is, when an abnormality occurs, an abnormality signal is transmitted to a monitoring center device via a telephone line, or a dedicated monitor is provided at a service base. There is a remote monitoring and diagnostic device that can be used to check the operating status of the elevator and to remotely control it using a device.In order to quickly return to normal operation when the seismic detector operates, the remote monitoring and diagnostic device can be used. The service site will check if the earthquake detector works.

[0008]

In the conventional elevator seismic control operation system described above, for example, 120
When an earthquake with a level exceeding Gal occurs over a wide area and the low detectors of each elevator operate, and many elevators are in a dormant state, specialized technology is required to restore all of these elevators to normal operation. It is necessary to mobilize a large number of specialists because it requires an operator to inspect each elevator and a specialist to reset the low sensor in the elevator machine room. In addition, when performing the above-mentioned elevator inspection work and low sensor reset work, a professional engineer has to move up and down the stairs many times because of the reciprocation of the building to the elevator machine room, which causes physical fatigue. In addition to the above, it takes a long time such as at least half a day to restore all the stopped elevators, which causes a problem that the burden on the technician becomes considerably large.

In particular, when the above-mentioned earthquake occurs on a holiday or at night, the elevator must be restored quickly. Therefore, an expert engineer of the elevator must be dispatched in a fully mobilized state immediately despite the holiday and night. However, there is a problem that not only the physical burden described above but also the mental burden increases. Furthermore, when the elevator is out of operation due to the operation of the low sensor, it takes at least one hour from the start of inspection of the elevator to the return to normal operation after the arrival of the expert engineer. There is also the problem of causing great inconvenience to people.

Further, the above-mentioned conventional seismic control operation device for an elevator can secure the safety of passengers in the car when an earthquake occurs, and can prevent an unexpected accident due to a serious functional deterioration of the elevator. However, due to the problem that the cost required for installation is high, it is the current situation that when installing a new elevator, it is rare to install a seismic control operation device or additionally install it on an existing elevator. In particular, when the seismic control operation device is additionally attached to the existing elevator, the cost of the installation work and the like in addition to the cost of the seismic detector main body is relatively high, and the total cost of these is high.

When installing the seismic control operation device in the elevator, first, make a hole in the floor of the elevator machine room, embed an anchor bolt, and attach a bracket to this anchor bolt to install the seismic detector in the elevator machine room. Work to firmly fix it to the floor of the elevator, work to fix the pipe for pulling the signal cable of the seismic detector to the control panel in the elevator machine room on the floor of the elevator machine room, and earthquake detection on the control panel. It is necessary to install a terminal for receiving the signal from the operating contact of the equipment, and to connect from this terminal to a predetermined terminal of the input interface section of the elevator control device, and the cost of such installation work is as described above. It becomes expensive. Further, the material cost of material is large for the equipment cost of the seismic detector main body, and the other material cost includes the cost of the bracket, the signal cable, and piping for passing the cable.

The present invention has been made in view of the actual situation in the prior art as described above, and an object thereof is to perform seismic control operation of elevators in each area when an earthquake occurs, and at a low installation cost. Another object of the present invention is to provide a seismic control operation device for an elevator that can quickly perform recovery work after an earthquake.

[0013]

In order to achieve the above object, the present invention provides a seismic control operation apparatus for an elevator, which performs seismic control operation for a plurality of elevators when an earthquake exceeding a predetermined level occurs. An area where a plurality of elevators are installed is divided into a plurality of predetermined areas, and in each of these areas, at least one earthquake detector that detects the earthquake, and an earthquake of an elevator that does not include the earthquake detector Operation control means for performing control operation according to the seismic control operation command is provided, and when the seismic sensor operates, seismic control operation of an elevator located in the same area as the seismic sensor is performed.

[0014]

Since the present invention is configured as described above, when an earthquake detector provided in each of a plurality of regions detects an earthquake, the seismic detectors located in the region are controlled by the operation control means. Perform seismic control operation of elevators not equipped. As a result, the seismic control operation of elevators can be performed in each area when an earthquake occurs, and the number of earthquake detectors installed can be reduced as a whole, so installation costs are low and recovery after an earthquake occurs. Work can be done quickly.
