Description

The present invention relates to an elevator guide rail fixing device for fixing a guide rail to a hoistway.

As a conventional elevator guide rail fixing device, an elevator guide rail fixing device is known that includes a wall side bracket that is fixed to a hoistway and a rail side bracket to which a guide rail is fixed. In this elevator guide rail fixing device, the horizontal part of the wall-side bracket and the horizontal part of the rail-side bracket are stacked on top of each other, and each horizontal part is fixed using bolts arranged so as to extend in the vertical direction. fixed (for example, see Patent Document 1).

JP2013-151336

The distance between the back of the guide rail fixed to the hoistway and the wall of the hoistway is determined by the distance between the back of the guide rail fixed to the hoistway and the wall of the hoistway, since the horizontal part of the wall-side bracket and the horizontal part of the rail-side bracket are fixed in a stacked state. Depends on the length of the horizontal part of the wall bracket that protrudes from. Here, in order to widen the effective dimension when arranging elevator equipment in the hoistway, there is a means of reducing the distance between the back surface of the guide rail and the wall of the hoistway. In this method, in order to reduce the distance between the back surface of the guide rail and the wall of the hoistway, it is necessary to reduce the length of the horizontal portion of the wall-side bracket that projects from the wall of the hoistway. On the other hand, since bolts arranged so as to extend in the vertical direction are provided in this horizontal portion, a space must be secured for the arrangement of the bolts. Therefore, it is difficult to make the length of this horizontal portion smaller than the space in which this bolt is provided.

This invention was made to solve the above-mentioned problems, and its purpose is to reduce the length of the horizontal part of the wall bracket that protrudes from the wall of the hoistway, and to reduce the length of the back side of the guide rail. An object of the present invention is to provide an elevator guide rail fixing device that can reduce the distance between the elevator and the wall of the hoistway.

The elevator guide rail fixing device according to the present invention includes a wall-side bracket that is fixed to the inner wall of the elevator hoistway, and a rail-side bracket that comes into contact with the back surface of the elevator guide rail to support the guide rail. In an elevator guide rail mounting device that fixes a guide rail to a wall bracket via a rail side bracket, it is provided on the wall side bracket, and when the side of the guide rail is viewed from the horizontal direction on both sides of the guide rail, one side is attached to the guide rail. When viewed from the front in the width direction of the guide rail, the guide rail is sandwiched between a pair of first extension parts that overlap with each other on the back side of the rail, and the other extends toward the inner wall of the hoistway . A notch part formed at the position, a contact part provided on the rail side bracket that comes into contact with the back side of the guide rail, and one side of the guide rail when viewed from the horizontal direction on both sides of the guide rail. A pair of second extension parts are placed on top of each other on the back side of the guide rail, and the other extends from the back side of the guide rail to the first extension part side. a pair of third extending parts arranged overlapping each other and extending from the abutting part to the second extending part; an opposing part where the first extending part and the second extending part face each other and abut; a connecting part provided in the section and connecting the first extending part and the second extending part, the width of the notch part is formed larger than the width of the guide rail, and the width of the notch part is formed larger than the width of the guide rail ; and the third extending part are formed to have the same width when viewed from the front in the width direction of the guide rail, and the second extending part is arranged to overlap the lower part of the third extending part. The back surface of the guide rail is located at a position overlapping the notch when viewed from the vertical direction.

This invention provides an elevator guide rail fixing device that can reduce the distance between the back surface of the guide rail and the hoistway wall without reducing the length of the horizontal portion of the wall bracket that protrudes from the hoistway wall. can be realized.

It is possible to realize an elevator guide rail fixing device that can reduce the distance between the back surface 31 of the guide rail 3 and the inner wall 1 of the hoistway.

Note that, when viewed from the vertical direction, the position where the back surface 31 of the guide rail 3 overlaps the notch 22 is not limited to the position disclosed in the first embodiment. For example, by further extending the contact portion 40 side of the third extending piece 42 toward the inner wall 1 side, the back surface 31 of the guide rail 3 can be brought closer to the inner wall 1 side.

Further, it is easy to further extend the contact portion 40 side of the third extending piece 42 toward the inner wall 1 side, and there is no particular problem. That is, it is sufficient to secure a space in which the fixing bolt 5 can be fastened by inserting a tool from the side directly above the fixing bolt 5, and by further extending the contact portion 40 side of the third extension piece 42 toward the inner wall 1 side, This space is never compressed.
