Description

  The present invention relates to a cleaning device and method for a tread groove of a passenger conveyor.

  A plurality of grooves along the moving direction are provided on a footboard of a passenger conveyor such as an escalator or a moving sidewalk. Foreign matter such as dust adheres to the groove, or splashes of the lubricating oil that lubricates the gears and chains that drive the passenger conveyor accumulate. There is a problem that foreign matter such as dust impairs the aesthetic appearance and is hindered in driving the passenger conveyor by being sandwiched between the comb members of the landing plate provided at the end of the passenger conveyor. Moreover, the oil adhering to the surface of the tread board and the groove may cause a slip when the passenger gets on the conveyor. For this reason, it was necessary to clean the footboard of the passenger conveyor.

  As described above, since the tread has a groove, a large amount of foreign matter and oil accumulate in the groove. Therefore, a method is used in which a cleaning brush is attached to remove foreign matter and oil accumulated in the groove of the footboard of the passenger conveyor. In this case, in order to clean the vicinity of the yellow painted surface arranged on both sides of the tread board, the diameter of the brush hair entering the groove near the both side edges of the tread board is made larger than that of the other parts and its rigidity It has been proposed to increase the length or lengthen the length (for example, see Patent Document 1).

  Further, although a method of cleaning the tread board by rotating the brush is used, when the brush is simply rotated, the brush hits the edge of the groove of the tread board, and only the brush in this portion is worn. In view of this, a method has been proposed in which the base of the brush is covered with a cylindrical cover, and the inside of the tread plate groove is cleaned by the brush portion protruding from the tip (see, for example, Patent Document 2).

  However, garbage and oil are collected together in the tread groove. In particular, both ends of the footboard are rich in oil due to splashes of lubricating oil. In this way, when dust and oil are collected together, as in the prior art described in Patent Documents 1 and 2, dust and oil are removed with a brush and cleaning is gradually performed. There is a problem that dust and oil adhere to each other and eventually the foreign matter that is integrated with dust and oil cannot be removed from the brush, making it impossible to clean the groove. . For this reason, in the cleaning method using a brush, it was necessary to change a brush intricately, and there existed a problem that the efficiency of cleaning work worsened. Also, once the dust adhered between the brush bristles and the oil brush bristles, they cannot be reused by simple care to wipe off the brush surface. There was a problem that efficiency would deteriorate.

  An object of this invention is to clean the tread board of a passenger conveyor effectively with a simple structure.

  A passenger conveyor footboard cleaning device according to the present invention includes an elastic flat plate that is inserted into a groove of a footboard of a passenger conveyor, and an attachment member that attaches the flat plate to a non-movable part of the passenger conveyor, and operates the passenger conveyor.
