[0017] Figure 3 3D is a three-view diagram of a control panel housing closing plate according to Embodiment 1. DETAILED DESCRIPTION

[0018] Hereinafter, the embodiments will be described with reference to the accompanying drawings. For common or corresponding elements in each figure, the same reference numerals are marked to simplify or omit the description. The structure shown in the embodiment shown below represents an example of the technical idea of ​​the present disclosure, and can also be combined with other well-known technologies, and can also combine multiple technical ideas recorded in the present disclosure. In addition, part of the structure can be omitted or changed within the scope of the main purpose of the present disclosure.

[0019] Implementation method 1.

[0020] Figure 1 is a three-dimensional diagram showing the old control panel housing. Figure 1 As shown, the old control panel housing 2 is installed in the machine room of the elevator. The old control panel housing 2 is updated to a new control panel 8 in the elevator update project. The old control panel housing 2 can be separated into two parts, an upper housing part 3 and a lower housing part 4. The lower housing part 4 is fixed to the ground by anchors buried in the concrete ground. The upper housing part 3 is fixed to the lower housing part 4 by bolts. The upper housing part 3 and the lower housing part 4 each have a rectangular parallelepiped shape.

[0021] Figure 2 This is a perspective view showing the elevator machine room work platform 5 according to the first embodiment. Figure 2 Equivalent to Figure 1 The figure is viewed from the direction of arrow A. Figure 2 As shown, the elevator machine room work platform 5 includes: the lower housing portion 4 of the old control panel housing 2; and the control panel housing closing plate 6, which has a top plate portion 7, and the top plate portion 7 covers the opening portion above the lower housing portion 4 when the upper housing portion 3 is separated from the lower housing portion 4. The upper surface of the elevator machine room work platform 5, that is, the top plate portion 7 is horizontal.

[0022] According to the present embodiment, the control panel housing closing plate 6 covers the opening formed above the lower housing portion 4, thereby making it possible to safely work around the lower housing portion 4 even when the lower housing portion 4 is installed. In addition, the lower housing portion 4 of the old control panel housing 2 can be used as an elevator machine room workbench 5. For example, a maintenance computer can be placed on the elevator machine room workbench 5 for use. In addition, since there is no need to cut the lower housing portion 4 from the ground, the trouble of cutting can be eliminated, and the risk of injury during cutting can be eliminated. In addition, a tool box can be placed inside the control panel housing closing plate 6.

[0023] like Figure 2 As in the example of the present invention, the new control panel 8 may be arranged near the old control panel housing 2. A power line or an intercom line is introduced into the lower housing portion 4. In order to connect these wirings to the new control panel 8, a terminal block for connecting the power line or the intercom line in the lower housing portion 4 and the wiring connected to the new control panel 8 may be provided inside the elevator machine room workbench 5. Thus, the space inside the elevator machine room workbench 5 can be used as a space for providing the terminal block.

[0024] Figure 3 1 is a three-view diagram of the control panel housing closing plate 6 of Embodiment 1. Figure 3 As shown in FIG. 1 , the top plate 7 is in the shape of a rectangular plate. The control panel housing closing plate 6 of the present embodiment further includes a side panel 9, which covers a cutout 10 provided on the upper side of the lower housing portion 4. Figure 3 The cutout 10 of the lower case portion 4 is indicated by a dotted line. According to the present embodiment, the cutout 10 is closed by the side surface plate 9 of the control panel case closing plate 6, so that work can be performed safely around the cutout.

[0025] The top plate portion 7 and the side panel portion 9 of the control panel housing closing plate 6 are connected at the side along the short side direction of the top plate portion 7, and the top plate portion 7 and the side panel portion 9 are formed to be substantially perpendicular. The side panel portion 9 protrudes downward from the end of the top plate portion 7. Thus, the cutout portion 10 can be covered without a gap. In the example shown in the figure, the side panel portion 9 is provided at both ends of the long side direction of the top plate portion 7. The side panel portion 9 is rectangular.

[0026] The length of the top plate 7 in the long side direction is longer than the length between the opposite side surfaces of the lower housing 4. That is, the distance L1 between the side panel 9 and the side panel 9 on the opposite side is longer than the length of the corresponding portion of the lower housing 4. Therefore, when the top plate 7 is arranged at the opening above the lower housing 4, the side panel 9 is arranged at a position further outward than the side surface of the lower housing 4. As a result, the cutout 10 is not exposed to the outside, so that work can be performed more safely in the surrounding area.

[0027] The control panel housing closing plate 6 of the present embodiment also includes an auxiliary plate portion 11, which is provided on the side surface along the long side direction of the top plate portion 7. The top plate portion 7 and the auxiliary plate portion 11 are formed to be approximately perpendicular. The auxiliary plate portion 11 protrudes downward from the edge of the top plate portion 7 along the long side direction. In the example shown in the figure, the auxiliary plate portion 11 is provided at both ends of the short side direction of the top plate portion 7. The auxiliary plate portion 11 is arranged at a position further outward than the side surface of the lower housing portion 4 along the long side direction of the top plate portion 7. Thereby, the top plate portion 7 can be reliably prevented from shifting in the short side direction. The auxiliary plate portion 11 is provided over the entire length of the top plate portion 7. The auxiliary plate portion 11 is rectangular in shape.

[0028] The side panel portion 9 is provided with a fixing hole portion 12. When the top plate portion 7 is arranged at the opening portion of the lower housing portion 4, the fixing hole portion 12 is arranged at a position communicating with a side fixing hole 13 of the lower housing portion 4, and the side fixing hole 13 is used to connect the lower housing portion 4 and the upper housing portion 3. Thus, it is possible to fix the control panel case closing plate 6 with bolts by screwing the bolts inserted into the fixing hole portion 12 into the side fixing hole 13 without providing new bolt holes in the lower housing portion 4.

[0029] The control panel updating method disclosed in the present invention includes: an upper housing portion separation step, in which the upper housing portion 3 of the old control panel housing 2 of the elevator which is arranged in the machine room and separated into the upper housing portion 3 and the lower housing portion 4 is separated and removed; a control panel housing closing plate configuration step, in which a control panel housing closing plate 6 having a top plate portion 7 is configured, and the top plate portion 7 covers the opening portion generated above the lower housing portion 4 from which the upper housing portion 3 is removed; and a new control panel configuration step, in which a new control panel 8 is configured. The order of the steps is not limited to the above order. For example, the new control panel configuration step may also be set as the first step, or the new control panel configuration step may be set as the second step. In addition, the control panel updating method disclosed in the present invention may also include the following terminal block production step: a terminal block is set inside the control panel housing closing plate 6, and the terminal block is used to connect the power line or intercom line introduced into the lower housing portion 4 with the wiring connected to the new control panel 8.
