Description

  The present invention relates to an elevator control panel renewal method for updating an elevator control panel from an existing control panel to a new control panel.

  When decades have passed since the elevator was installed in a building or the like, the elevator control system becomes obsolete, and the service degradation for elevator users becomes conspicuous. In such a case, rather than refurbishing and replacing the car that constitutes the elevator and the drive mechanism that raises and lowers the car in the hoistway, the control panel that incorporates a control unit that controls the operation of the drive mechanism is updated to a new control panel. (Renewal) may be more effective.

  Hereinafter, a procedure for updating the elevator control panel from the existing control panel to a new control panel will be described with reference to the schematic configuration diagram of the elevator shown in FIG.

  A drive mechanism comprising a hoisting machine 6 and an electric motor 7 for raising and lowering a car 4 and a counterweight 5 in the hoistway 1 on a concrete floor 3 of a machine room 2 provided on the upper side of the elevator hoistway 1. 8 are provided. A control panel 9 incorporating a control unit for controlling the operation of the drive mechanism 8 is also provided. The control panel 9 is fixed to the upper surface of a mounting base (pool box) 10 embedded in the concrete floor 3 with bolts, for example. The mounting base 10 is formed in a box shape having an upper end opening, for example, and the control panel 9 is fixed to the end surface near the opening of the mounting base 10 with bolts.

  A wiring duct 11 is formed between the drive mechanism 8 and the control panel 9 in the concrete floor 3 of the machine room 2, and the upper surface of the wiring duct 11 is covered with a duct cover 12. In the wiring duct 11, a signal cable 13 that connects the control panel 9 and the drive mechanism 8 and the control panel 9 and the car 4 is laid. The signal cable 13 is routed in the control panel 9 from the lower surface of the control panel 9 via the wiring duct 11 and the mounting base 10, and is connected to a signal terminal provided in the control panel 9. .

  In the case where the existing control panel 9 in the elevator configured as described above is updated (renewed) to a new control panel, generally, the new control panel equipped with the latest electronic components is replaced with the existing control panel 9. In comparison, since it is formed in a small size, the existing mounting base 10 embedded in the concrete floor 3 cannot be used as it is as a mounting base for a new control panel.

Therefore,
(1) Remove the signal cable 13 from the existing control panel 9,
(2) Remove the existing control panel 9 from the existing mounting base 10,
(3) Remove the existing mounting base 10 from the concrete floor 3,
(4) A new mounting base is attached to the concrete floor 3,
(5) Install a new control panel on a new mounting base,
(6) It was necessary to perform six steps of work, such as connecting the signal cable 13 to a new control panel.

  Further, depending on the size of the new control panel, it is necessary to extend or recreate the existing wiring duct 11 formed on the concrete floor 3.

In Patent Document 1, when an existing control panel is updated to a new control panel larger than the existing control panel, a shape larger than the upper surface of the existing pool box is formed on the upper surface of the existing pool box (mounting base). A technique has been reported in which a spacer having a spacer is attached and a new control panel is mounted on the upper surface of the spacer. In addition, the support body is interposed between the part which protrudes from the edge part of the existing pool box in a spacer, and a floor.
