Description

  The present invention relates to a method for replacing an existing car operation panel or the like installed in an elevator car and a structure of a car for replacing an existing car operation panel or the like.

  4 to 7 show a method for replacing a conventional car operation panel or the like (see Patent Document 1), FIG. 4 is a perspective view showing a main part in an existing elevator car, and FIG. 5 shows a car operation panel or the like. FIG. 6 is a cross-sectional view taken along the line II-II in FIG. 5, and FIG. 7 is a perspective view showing the back surface of the mounting plate in FIG.

In the figure, reference numeral 1 denotes an elevator car, which includes a floor 2, side walls 3, an entrance / exit 4, a ceiling 5, a sleeve wall 6, and the like. 7 is an existing car operation panel attached to the sleeve wall 6, 8 is a telephone box, and 9 is a nameplate.
Reference numeral 10 denotes a new mounting hole provided in the sleeve wall 6, 13 a new car operation panel, and 14 a box. Reference numeral 16 denotes a mounting plate superposed on the sleeve wall 6, a new instrument mounting hole 17 to which a new car operation panel or the like is mounted, a screw rod 18 inserted through a through hole formed in the sleeve wall 6, and a screw rod 18. A fastener 20 including a nut 19 and a refracting portion 21 are provided.

In order to replace the fixtures 7, 8, 9 such as the existing car operation panel 7, the existing fixtures 7, 8, 9 are first removed. Next, a new tool mounting hole 17 of the mounting plate 16 and a new mounting hole 10 corresponding to the refracting portion 21 and a through hole corresponding to the screw rod 18 are processed in the sleeve wall 6. Then, the bending portion 21 is inserted into the attachment hole 10 and the attachment plate 16 is fixed to the sleeve wall 6 by the fastener 20.
Next, the box 14 of the new car operation panel 13 is fixed to the refracting portion 21 with the fastener 15 and the front plate of the new car operation panel 13 is attached to the box 14, thereby completing the replacement.

  In the prior art, a new mounting hole 10 must be formed in the sleeve wall 6. Although it is necessary to make this processing work into a shape corresponding to the newly installed tool mounting hole 17 and the refracting portion 21, there is a problem that it is not easy to accurately process in the car 1 having poor working conditions.

The present invention, after removing the car operating panel or the like from the sleeve wall, the mounting cover plate sleeve wall, to fix the support with the mounting holes in the adjacent side wall and the cover plate of the sleeve wall, the new A car operation panel or the like is attached to the attachment hole. As a result, special on-site processing on the sleeve wall is omitted, and the work is facilitated.
Further, a hole is provided in the cover plate in advance, and after the existing car operation panel or the like is removed, the existing mounting hole formed in the sleeve wall and at least a part of the hole are superposed. As a result, a wiring cable such as a new car operation panel can be taken out of the car through both holes.

  According to the present invention, it is possible to reduce processing work in a car having poor work conditions, so that work efficiency can be improved, and a car operation panel is attached to a new support, so that the car image can be greatly changed. .

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a view showing the progress of the replacement operation of the car operation panel, etc., FIG. 2 is a view showing a completed state of replacement, and FIG. 3 is an explanatory view corresponding to a cross section at the center of FIG.
In order to replace the car operation panel or the like, first, the existing car operation panel or the like is removed, and the mounting hole 30 is exposed. Next, three round holes are made in each of the sleeve wall 6 and the side wall 3, and a turn nut is inserted. Then, a cover plate 31 having an L-shaped cross section having a hole 31a at a position overlapping the round hole and the existing mounting hole 30 in advance at the position of the round hole, one side of which is aligned with the entrance / exit post 4a and the lower end with the kick plate 2a Affix to the sleeve wall 6 with double-sided tape. The end 31b is bent to form a reinforcing piece.

Next, a surface plate 40 having a cross-sectional shape in which both sides are bent twice and having holes 40a and 40b for mounting a car operation panel or the like on the surface, and a reinforcing member 41 fixed at three places on the back side thereof, A support 42 having a shape with Here, a hole 41a is formed in the reinforcing member 41 in advance at the position of the round hole. Then, using the space at the lower end of the mounting holes 40a and 40b and the support 42, the support 42 is screwed into the turn nut from the hole 41a of the reinforcing member 41, so that the support 42 has the sleeve wall 6, the cover plate 31 and It is fixed to the side wall 3.
Further, a new car operation panel 50 and a car position indicator 51 are attached to the mounting holes 40a and 40b, and the wiring cable 50a goes out of the car 1 from the hole 31a and the existing mounting hole 30 and is wired.

  As described above, according to the present embodiment, the processing on the car 1 at the site only requires three round holes in the sleeve wall 6 and the side wall 3 respectively, so that the car 1 can be processed in the car 1 as compared with the prior art. The machining work is extremely reduced. Further, in this embodiment, since the car operation panel 50 and the like are attached to the newly provided support body 42, the image of the car 1 can be greatly changed as compared with the conventional case.

  In the above embodiment, the cover plate 31 is affixed to the sleeve wall 6 using only double-sided tape. However, since the portion covered with the support 42 is not visible from within the car, screwing may be used here. Moreover, the hole 31a of the cover board 31 should just overlap with the existing attachment hole 30 at least partially. Furthermore, the number of turn nut holes is not limited to six, and the number of reinforcing members 41 is not limited to three.

It is a figure which shows embodiment of this invention and is a figure which shows progress in the middle of replacement work, such as a car operation panel. It is a figure which shows embodiment of this invention and is a figure which shows the replacement completion state. It is explanatory drawing equivalent to the cross section of the center part of FIG. It is a perspective view which shows the principal part in the existing elevator car. It is a figure explaining the replacement | exchange method of the conventional car operation panel etc. FIG. It is the II-II sectional view taken on the line of FIG. It is a perspective view which shows the back surface of the mounting plate of FIG.
