Description

  The present invention relates to an elevator inspection apparatus, and more particularly, to an elevator inspection apparatus that inspects the inside of a hoistway in a state where a car is stopped, such as restoration inspection work after an earthquake.

  Many elevators are equipped with a seismic control operation device that automatically stops the operation of the elevator when a shake is detected in order to protect the safety of the user in the event of an earthquake. Specifically, the earthquake control operation device is a device that automatically stops the car on the nearest floor and opens the door when a sensor attached to the elevator detects a certain amount of shaking. And when a strong shake (for example, seismic intensity 4 or more) that is assumed to cause damage to the building is detected and the operation is stopped, the restoration is prohibited until an inspection by a professional engineer is performed.

  In restoration inspection work after a strong earthquake, it is important to check the damage status in the hoistway before moving the car during trial operation, etc., from the viewpoint of ensuring the safety of inspection workers and preventing damage to equipment. . However, although the machine room and the pit can be visually inspected relatively easily, it is not easy to confirm the entire hoistway with the car stopped. Especially in a high-rise elevator with a long hoistway, the confirmation work is extremely difficult.

  Several techniques for inspecting the inside of a hoistway have been proposed as techniques related to the present invention. For example, Patent Document 1 discloses a system that remotely checks online elevator images by using a surveillance camera installed in a machine room, a hoistway, the outside of a car, and the like to check whether there is an abnormality in the elevator. Yes. Also, a system (see Patent Document 2) in which a surveillance camera is installed in equipment that constitutes an elevator such as a counterweight (see Patent Document 2), or a system that has a surveillance camera configured to be able to photograph the upper part of the car ceiling (see Patent Document 3). ) Is also disclosed.

  However, according to the technique disclosed in the above-mentioned patent document, since the camera is installed on the car and the counterweight, the state in the hoistway cannot be inspected in detail unless the car is operated. Even if a camera fixed to the hoistway is used, it is not easy to confirm the entire hoistway. In particular, in a high-rise elevator, in order to enable inspection over the entire length of the hoistway, it is necessary to install a large number of cameras in the hoistway, which increases the cost of introduction and maintenance.

  An object of the present invention is to provide an elevator inspection device that can easily and quickly carry out inspection over the entire length of a hoistway even when a car is stopped, such as restoration inspection work after an earthquake. Is to provide.

  An elevator inspection apparatus according to the present invention is an elevator inspection apparatus that inspects the inside of a hoistway in a state where a car is stopped, and is connected to the imaging apparatus that images the inside of the hoistway, and the imaging apparatus. And a drive device that moves along the guide rail. Moreover, it is preferable that this inspection apparatus is not an apparatus permanently installed in the hoistway but an apparatus that can be easily introduced into the hoistway at the time of inspection.

  According to the above configuration, since the imaging device moves along the guide rail, an image in the hoistway can be acquired over the entire length of the hoistway even when the car is stopped. In addition, since this inspection apparatus is an apparatus that can be easily introduced into and removed from the hoistway, it is not necessary to permanently install it in one elevator and can be used in a plurality of elevators.

  The drive device is disposed opposite to both sides of the guide rail installed in the hoistway, and has wheels that sandwich the guide rail from both sides, an electric motor that drives at least one wheel, and biases the wheels against the guide rail. It is preferable to have an urging means.

  According to the above configuration, the imaging device can be stably moved along the guide rail without dropping the inspection device from the guide rail, and a clear image without blur can be obtained. In addition, since the car guide rail and the counterweight guide rail are installed in the hoistway over almost the entire length, the inspection device is attached to one of the guide rails, and an image is taken at an arbitrary position on the hoistway. Can be acquired.

  The driving device includes a wheel that abuts on a guide rail installed in the hoistway, an electric motor that drives at least one wheel, and a magnet that is attracted to the guide rail. And a magnet for biasing the guide rail. In addition, the installation position and size of the wheel urged by the magnet are determined so as to maintain an appropriate distance where the attractive force acts between the guide rail and the magnet.

  According to the above configuration, the movement of the imaging device along the guide rail becomes more stable. That is, since the car guide rail and the counterweight guide rail are made of metal, if the magnet is mounted on the driving device, the magnet is attracted to the guide rail and the wheel is pressed against the guide rail.

  The imaging device or the driving device includes a battery and a receiver that receives a wireless operation signal, outputs a wireless operation signal to the receiver, and remotely operates the operations of the imaging device and the driving device. A controller is preferably provided. Since the place where the inspection work is performed differs depending on the stop position of the car, the controller is more preferably a portable portable device.

  According to the above configuration, since the drive device can supply power to the imaging device and the drive device with the built-in battery, a power supply cable or the like is not necessary, and the inspection device can be attached and moved smoothly. Further, a simpler and quicker inspection can be realized by using a controller that remotely controls the imaging device and the driving device as the inspection device body.

  The imaging device preferably includes a transmitter that transmits the acquired image data and that receives the image data from the transmitter and displays the image. It is more preferable to use a terminal device in which the monitor device and the controller are integrated.

  According to the said structure, it becomes possible to confirm the image image | photographed moving in the hoistway in real time with the monitor apparatus in the hand of an inspection operator. In particular, if a terminal device in which a controller and a monitor device are integrated is used, it is easy to control the inspection device body while confirming an image, so that the accuracy and convenience of inspection can be further improved.

  Moreover, it is preferable to provide the illuminating device which is installed in an imaging device or a drive device, and moves along a guide rail with an imaging device.

  According to the said structure, since the inside of a dark hoistway can be illuminated with an illuminating device, a favorable image can be obtained. Since the illumination device moves together with the imaging device, it is possible to illuminate a place necessary for taking an image without installing a large number of illumination devices in the hoistway. Except for a see-through elevator or the like, it is effective to use such a lighting device in a hoistway surrounded by a wall of a general building in order to obtain a good image.

  According to the elevator inspection apparatus of the present invention, it is possible to easily and quickly carry out inspection over the entire length of the hoistway even when the car is stopped, such as restoration inspection work after an earthquake. become.
