Description

  The present invention relates to a take-out device for a control device for a man conveyor such as an escalator or a moving sidewalk.

In general, man conveyors such as escalators and moving walkways are connected endlessly and circulate and move in the main frame, a driver equipped with an electric motor that drives the steps, and a machine room that houses the driver. And a panel mainly composed of a control panel provided in the machine room.
In order to inspect and maintain the drive machine and control panel, a maintenance worker must enter the machine room. However, in recent years, man conveyors have come to perform complicated controls such as variable control of speed, and it is necessary to equip the control panel with inverters, etc., which makes it unavoidable to increase the size and weight of the control panel. .
If it is going to arrange a drive machine and a board, ensuring work space, the size of a machine room, ie, a main frame, must be enlarged, and a problem will arise in the layout of a man conveyor itself. In addition, when trying to secure the work space in the machine room by taking the control panel out of the main frame, the operator must lift the control panel directly, and if the weight is large, multiple workers are required. There's a problem.
In order to solve such problems, there has been proposed a method of pulling up the control device of the man conveyor that can reduce the burden on the worker by taking out the control panel using the movement of the steps or the moving handrail ( For example, see Patent Document 1).
