Description

Erebe evening rail mounting equipment

The present invention relates to a rail mounting device for an elevator for mounting a guide rail for guiding an elevator for an elevator to an inner wall surface of a hoistway. Background art

In a traditional elevator overnight, multiple guide rails may be installed in the hoistway to guide the car and counterweight. Each guide rail is fixed in the hoistway by a fixed bracket. Japanese Utility Model Publication No. 4-5 6 1 7 9 discloses a reinforcing material arranged in the hoistway separately from the fixing bracket in order to reinforce the fixing of the guide rail. The reinforcing material is fixed to the other inner wall surface perpendicular to the one inner wall surface to which the fixing bracket is fixed. In addition, the reinforcing material is arranged so as to be shifted in the height direction with respect to the fixed bracket.

Japanese Utility Model Publication No. 5 5-1 1 9 94 describes a guide rail fixing bracket that can adjust the position of the guide rail in the horizontal direction. This guide rail fixing bracket has a wall side bracket that is fixed to the inner wall surface of the hoistway and a rail side bracket that is attached to the wall side bracket and whose position relative to the wall side bracket can be adjusted. The rail side metal fitting has a vertical part arranged in parallel with the inner wall surface of the hoistway, and a horizontal part extending from the lower edge of the vertical part to the inner wall surface side (the back side of the vertical part) of the hoistway. . The horizontal part is provided with a long hole through which a mounting bolt for mounting the rail side metal fitting to the wall side metal fitting is passed. By adjusting the position of the mounting bolt with respect to the elongated hole, the position of the rail side bracket relative to the wall side bracket can be adjusted.

However, in the conventional elevator shown in Japanese Utility Model Publication No. 4 5 6 1 7 9, the reinforcing material is separated from the fixed bracket, so the fixed bracket and the reinforcing material are moved up and down. It must be attached to the inner wall of the road one by one, and it takes time to install the guide rail in the hoistway. In addition, in the conventional elevator shown in Japanese Utility Model Publication No. 5 5-1 1 9 94, the horizontal part of the rail side metal fitting is located on the back side of the vertical part. When attaching to the wall bracket with mounting bolts, the inner wall surface and vertical part of the hoistway become an obstacle, and it takes time to tighten the mounting bolts.
