Embodiment Construction
[0016] Embodiments of the present invention will be described below with reference to the drawings.
[0017] First, use figure 1 with figure 2 , to describe the overall structure of the elevator inspection device 100 of this embodiment. here, figure 1 is a diagram expressing the elevator inspection device 100 in functional blocks, figure 2 It is a diagram represented by a hardware block.
[0018] exist figure 1 In the functional block diagram of , 1 is the car of the elevator that passengers enter. 2a and 2b are the landing doors that open and close the entrance and exit of the elevator hall. Hereinafter, they are sometimes combined and referred to as the landing door 2. 3a is the obstacle detection device equipped in the landing door 2, that is, the safety touch panel. A safety device that acts when a user, etc., moves the door in the opposite direction to the opening direction. Reference numeral 4 denotes an elevator car operation panel that an elevator user operate...

When a safety touch panel of a landing door of an elevator is inspected by employing a robot, the robot may fall down or get damaged due to impact during door closing. The invention provides an elevator inspection device comprising a landing door opening-closing unit for opening and closing a landing door of an elevator, a safety touch panel for detecting an obstacle in a processing of moving to the closing direction by the landing door, an overload door reverse unit for enabling the landing door to move to the reverse direction of the opening direction if an overload is applied to the landingopening-closing unit in a process of moving to the closing direction by the landing door, and an elevator monitoring unit for monitoring the landing door opening-closing unit, the safety touch paneland the overload door reverse unit. When there is no obstacle on a closing path of the landing door and the overload door reverse unit does not move, the landing door is fully closed in a usual mode in which passengers can use, the landing door moves to the closing direction for a predetermined distance and moves to the reverse direction of the opening direction before fully closing in an inspection mode in which the safety touch panel is detected by employing an autonomous robot.
Description
technical field [0001] The present invention relates to an elevator inspection device for inspecting elevators in an unmanned manner. Background technique [0002] In recent years, with the advancement of robot control technology, a part of the manual inspection of elevators has been gradually replaced by robots. [0003] For example, in the abstract of patent document 1, it is described that "provide an elevator equipped with an inspection system that uses sensors equipped in a self-propelled robot that patrols the building to automatically inspect the operating state and function", so , "The elevator has an inspection system. The inspection system has an elevator side communication device, an inspection control device, an inspection action command device, and a data processing device. The elevator side communication device is connected to the robot side communication device and communicates. The inspection control device is based on the information sent from the robot. Ca...
