Description

  The present invention relates to a passenger conveyor cleaning device suitable for removing dust accumulated on an oil receiving plate (oil pan) disposed below a plurality of steps connected endlessly. .

A conventional passenger conveyor cleaning device removes an arbitrary step from a plurality of steps connected endlessly, and then performs a long cleaning on the front wheel shaft to which the arbitrary step was attached. Attach one end side of the main body base directly, and provide a rake-like cleaning body on the other end side of the cleaning main body base, and move this cleaning body while making contact with the oil receiving plate. Of the multiple steps that are scraped or connected endlessly, any step is used as an inspection step that allows the tread plate member to be removed, and this step is attached. One end of the long cleaning main body base is directly attached to the front wheel shaft, and a rake-like cleaning body is provided on the other end of the cleaning main body base, and the cleaning body is moved while being in contact with the oil receiving plate. By letting Those as raking the dust receiving plate has been developed (e.g., see Patent Document 1).
JP 2002-20072 (paragraph number 0014 and paragraph number 0024 and FIGS. 2, 13 and 14)

  However, in the passenger conveyor cleaning device described in JP-A-2002-20072 described above, after removing an arbitrary step from a plurality of steps connected endlessly, the arbitrary step is Since one end of the cleaning body base is directly fixed to the attached front wheel shaft, when the rake-like cleaning body provided on the other end of the cleaning body base is moved, the position of the cleaning body However, the length of the cleaning body base and the cleaning body in the longitudinal direction must be sufficiently long so that the oil receiving plate can be sufficiently cleaned by contacting the oil receiving plate. There was a problem. Moreover, in the passenger conveyor cleaning device described in the above-mentioned JP-A-2002-20072, when the oil receiving plate is cleaned from the upper part to the lower part of the oil receiving plate and then the oil receiving plate is to be cleaned again. After removing the cleaning device on the lower entrance / exit side of the passenger conveyor, it is necessary to transport the cleaning device to the upper entrance / exit side of the passenger conveyor and attach it to the front axle again, and clean the oil receiving plate. There is a problem that becomes complicated.

  The object of the present invention has been considered in view of the above problems. Even if the length of the cleaning body base and the cleaning body in the longitudinal direction is shortened, the cleaning body provided on the cleaning body base can be used to clean the oil receiving plate. An object of the present invention is to provide a passenger conveyor cleaning device that can perform the above-mentioned operations well.

  Furthermore, the objective of this invention is providing the cleaning apparatus of the passenger conveyor which can clean an oil receiving plate repeatedly, without removing a cleaning apparatus from a step in addition to the said objective.

  In order to achieve the above object, the present invention provides a cleaning body base attached to one step among a plurality of steps connected endlessly, and a cleaning provided on one end side of the cleaning body base. And a cleaning device for a passenger conveyor that cleans the oil receiving plate by moving the cleaning member in contact with an oil receiving plate disposed below the plurality of steps. And at least one of the cleaning bodies is rotatably provided on one end side of the cleaning body base, and a fixed bracket body is rotatably provided on the other end side of the cleaning body base via a support shaft, For at least one step of the steps, the fixed bracket body is placed on the one step so that the tread member is removed and the support shaft is disposed at a portion where the tread member is removed. Solid It is characterized in that the.

  Furthermore, the present invention provides a first bracket part that fits and fixes the fixed bracket body to the structure of the one step, and the step that is connected to the first bracket part and has a tread member removed. And a second bracket portion locked to a front wheel shaft for attachment, and the other end side of the cleaning main body base is rotatably provided on the first bracket portion via the support shaft. It is said.

  Further, the present invention provides the cleaning body base, the cleaning body, when the cleaning body base is rotated about the support shaft and the cleaning body side is brought into contact with the mounting surface of the tread member of the step. The body, the support shaft, and the first bracket portion are arranged in a space occupied by the tread surface member in the one step.

  According to the present invention, the support shaft on which the other end side of the cleaning main body base is rotatably provided is disposed at the site where the tread member is removed and the tread member is removed. Since the length of the cleaning body base and the cleaning body in the longitudinal direction is the length that fits in the space occupied by the tread member at the step, the oil receiving plate can be cleaned. Well done.

  Furthermore, according to the present invention, the cleaning body base, the cleaning body, the support shaft, and the first bracket portion constituting the cleaning device are disposed in the space occupied by the tread member in the step, Since the cleaning device does not catch on the comb plate provided on the lower entrance / exit side of the passenger conveyor and the comb plate provided on the upper entrance / exit side of the passenger conveyor, the step is circulated while the cleaning device is attached to the step. Can be made. Therefore, it becomes possible to repeatedly clean the oil receiving plate without removing the cleaning device from the step, and it is possible to save labor in the cleaning work.
