Problems solved by technology

[0005] However, elevators with the above functions are limited to new models due to the constraints of the program loading area and program operation time.
For example, it is difficult to apply the above functions to the relay logic control elevator or the old model elevator that does not have an additional program writing area.
In this case, users or users are dissatisfied because it takes a long time for the elevator to resume operation; and maintenance technicians are physically fatigued by repeatedly going up and down the stairs, coupled with the aging of maintenance technicians, there may be Increase run recovery time

[0074] Figure 5 It is a system configuration diagram of an elevator earthquake inspection device in Embodiment 2 of the present invention, and the same reference numerals are assigned to the same or corresponding parts as in Embodiment 1, and description thereof will be omitted.

[0075] In the above-mentioned first embodiment, the connector 84 of the control box 8 on the lowest floor is connected to the cable connection end 94 of the remote control inspection operation device 9, so as to connect the most The lower floor control box 8 is connected with the remote inspection operation device 9 carried by the maintenance technician during the inspection. On the other hand, in Embodiment 2, the remote control inspection operation device 9a is made into a device equipped with a wireless connection function, and the lowest level control box 8a is also provided with the wireless connection function.

Abstract

The invention provides a checking device of an elevator when an earthquake happens, capable of confirming, among the lowest elevators or positions adjacent to them, whether there are damages to the elevator which has been stopped because of controlled action of an operation device when an earthquake happens so as to reduce physical fatigue of maintenance technicians. Once the earthquake sensor 6 senses an earthquake, the earthquake control operation device in an elevator control disc 5 acts to stop the elevator and check whether there are damages to the elevator. The elevator is recovered if there is no abnormal condition. The earthquake checking device of such elevator contains an additional substrate 7 in the control disc for checking when an earthquake happens, which is mounted in the elevator control disc; a lowest control box 8 which is connected onto the additional substrate in the control disc and mounted among the lowest elevators or positions adjacent to them; and a remote check running device 9 which is portable when checking and connected onto the lowest control box.

Description

technical field [0001] The present invention relates to an earthquake inspection device and repair method for an elevator capable of checking whether or not an elevator that is stopped by a control operation device during an earthquake is damaged (equipment damaged) in the lowest floor hall or its vicinity. Background technique [0002] In the past, in order to shorten the recovery time of the elevator that was stopped by the operation of the control operation device during the earthquake, it is known that the elevator operation program automatically checks whether the elevator is damaged, and if there is no abnormality, the elevator automatically resumes operation. [0003] For example, in the event of a stoppage due to an earthquake, the monitoring camera takes pictures of the machine room or the inside and outside of the car while performing an inspection operation, and sends the obtained image signal to the monitoring center together with the elevator operation data. The...
