Description

  The present invention relates to a passenger conveyor installation scaffold device including a plurality of unit scaffold devices arranged in series.

  When installing a passenger conveyor such as an escalator, a step of connecting frames divided in the longitudinal direction is performed as an initial operation. Steps for carrying passengers are incorporated in the frame described above, and the frame is connected in such a state that the steps are incorporated in the frame. However, if a step exists in the vicinity of the connecting portion, it becomes an obstacle to the connecting operation of the frame, and therefore the step in the vicinity of the connecting portion is removed. Therefore, at the end of the frame connection work, an opening from which some steps are removed is formed.

  Through the opening, a check operation of the state of attachment of the guide rail for guiding the running of the step is performed. Japanese Patent Application Laid-Open No. 2004-133867 discloses a conventional technique for ensuring safety during the confirmation operation. In this prior art, a working scaffold device is provided so as to close the vicinity of the central portion of the opening. This prior art has a configuration in which an engaging portion that engages with a front wheel of a step is attached, extends in the extending direction of the escalator, and a plurality of unit scaffolding boards that serve as scaffolds for installation work are provided in series.

  By the way, although the above-described guide rail check work is required even in the vicinity of the getting on / off portion of the escalator, in the prior art disclosed in Patent Document 1, there is a concern that workability in the vicinity of the getting on / off portion may be deteriorated. That is, since the shape of the guide rail that guides the traveling of the front wheel shaft includes a curved R portion in the vicinity of the escalator landing portion, the working scaffold device is installed on the front wheel shaft located in the R portion. Then, a step, that is, a gap that hinders work, is generated between a plurality of adjacent unit scaffold plates. Due to this gap, the installation operator is required to be careful and there is a risk that the work efficiency will be reduced.

  The present invention has been made based on the actual situation in the prior art described above, and its purpose is to arrange the scaffolding plates of a plurality of unit scaffolding devices without causing gaps that may hinder work even in the vicinity of the getting on / off portion. An object of the present invention is to provide an installation scaffold device for a passenger conveyor.

  In order to achieve the above object, a passenger conveyor installation scaffold device according to the present invention includes a locking portion that is locked to a front wheel shaft that is connected to an endlessly provided step chain, and the locking portion is attached thereto. A passenger conveyor comprising a plurality of unit scaffolding devices extending in the direction of extension of the passenger conveyor and having a scaffolding plate disposed so as to close a part of an opening formed by removing a step.

A connecting portion disposed on the upper side of the attachment portion, and connected to the connecting portion, extending in the direction of the scaffold plate of the adjacent unit scaffolding device, and the front wheel shaft. The front wheel roller attached to A parallel portion disposed substantially parallel to the guide rail inserted therein, and a bent portion that is connected to the parallel portion, extends in the direction of the scaffolding plate of the adjacent unit scaffolding device, and is bent downward. It is characterized by having a part.

  A passenger conveyor installation scaffolding device according to the present invention is a unit scaffolding plate bending portion located in front of a plurality of unit scaffolding scaffolding plates when the installation scaffolding device is disposed in the vicinity of a boarding / exiting unit. However, the state which contact | abuts to the connection part of the scaffolding board of the back unit scaffold apparatus adjacent to the said unit scaffold apparatus can be maintained. That is, according to the present invention, even in the vicinity of the boarding / alighting section, a plurality of scaffolds of unit scaffolding devices can be arranged without causing a gap that may hinder work between the scaffolding plates of adjacent unit scaffolding devices. . As a result, it is possible to easily and safely perform a guide rail check operation and the like, and improve the efficiency of the check operation and the like compared to the conventional method.
