  Embodiments of an elevator rail fixing device according to the present invention will be described below with reference to the accompanying drawings. In the drawings, the same reference numerals indicate the same or corresponding parts.

Embodiment 1 FIG.
As Embodiment 1, an elevator rail fixing device according to the present invention will be described as an embodiment for fixing a counterweight guide rail. FIG. 1 is a plan view of a hoistway to which an elevator rail fixing device of the present invention is applied.

  A car 3 and a counterweight 5 are arranged in the elevator hoistway 1 so as to be able to be raised and lowered. The car 3 and the counterweight 5 are respectively guided up and down by a pair of car guide rails 7 and a pair of counterweight guide rails 9 provided so as to extend vertically in the hoistway 1. The pair of counterweight guide rails 9 are fixed and supported by the pair of upright columns 11 by the rail fixing device 21 according to the first embodiment. The pair of car guide rails 7 is fixed and supported by the pair of upright columns 11 by a rail fixing device 121 according to the second embodiment to be described later.

  Each of the upright pillars 11 is disposed at an appropriate position in the hoistway 1 and extends vertically in the hoistway 1. The upright column 11 is a column member whose cross section is H-shaped. Although it is an example, the standing pillar 11 is prepared in the ratio which a pair respond | corresponds with respect to one rail fixing device. A pair of corresponding upright pillars 11 are erected in parallel with an interval between each other.

  Next, the rail fixing device according to the first embodiment will be described with reference to FIGS. FIG. 2 is a perspective view showing the overall configuration of the rail fixing device. FIG. 3 is a perspective view showing the relationship between a pair of flat plates, which are apparatus constituent members, and rail support beams. FIG. 4 is a perspective view showing the relationship between the pair of flat plates and rail support beams and the upright columns.

  The rail fixing device 21 includes at least a pair of flat plates 23, rail support beams 25, and rail bracket means 27. An iron plate is used as the flat plate 23. Each of the pair of flat plates 23 is attached to the front surface 11 a of the corresponding upright column 11. The front surface is a surface on the side to which the target rail (balance weight, car) is attached in the vertical pillar 11 having an H-shaped cross section, and can be said to be a surface on the center side of the hoistway in the present embodiment. The pair of flat plates 23 are fixed such that their back surfaces are along the corresponding front surface 11a of the upright column 11, and in this embodiment, in particular, the thickness direction of the flat plate 23 is fixed in a posture orthogonal to the front surface 11a of the upright column 11. Is done.

  As a specific example, in detail, the flat plate 23 is applied from the center of the hoistway along the front surface 11a of the upright column 11, and a corresponding vertical column is provided between the back surface of each flat plate 23 and the clip 29 (see FIG. 1). 11, one piece having the front surface 11 a is sandwiched, and the flat plate 23 and the clip 29 are fastened with bolts (screws) 31 and nuts 33 from the front and rear. Thereby, a pair of flat plate 23 is fixed to the front surface 11a of the standing column 11 corresponding. In addition, when it is desired to further increase the fixing strength of the pair of flat plates 23, the flat plates 23 may be welded to the upright columns 11. Also in this case, the welding operation may be performed from the center side of the hoistway.

  The rail support beam 25 is an L-shaped angle member whose cross section orthogonal to the longitudinal direction is L-shaped. The rail support beam 25 is fixed to the pair of flat plates 23 so as to bridge between the pair of flat plates 23. The rail support beam 25 includes a first flat plate portion 25a and a second flat plate portion 25b as main components. When the rail is fixed, the first flat plate portion 25a extends in the vertical direction, The flat plate portion 25b extends in the front-rear direction from the upper end of the first flat plate portion 25a to the rear. The rail support beam 25 is fixed between the pair of flat plates 23 by welding each end thereof to a portion protruding from the upright column 11 on the back surface of the corresponding flat plate 23.

  In the first embodiment, the rail bracket means 27 is composed of a pair of rail brackets 35 prepared corresponding to the pair of counterweight guide rails 9. Each of the pair of rail brackets 35 is made of an L-shaped angle material. The rear ends of the pair of rail brackets 35 are fixed to the rail support beam 25 by, for example, welding.

  A pair of counterweight guide rails 9 are fixed to the front ends of the pair of rail brackets 35 in a well-known manner using rail clips or the like. In this way, the pair of counterweight guide rails 9 are supported by the rail support beams 25.

  According to the rail fixing device of the present embodiment as described above and the rail fixing method using the same, it is possible to improve the workability of the rail fixing work while making the device space compact. . That is, in the present embodiment, the rail bracket means 27 is fixed to the rail support beam 25 instead of the front portion of the front surface 11a of the upright column 11, and accordingly, what is provided on the front surface 11a of the upright column 11 is described above. Instead of the L-shaped angle material as in the first aspect of Patent Document 1 and the first aspect of Patent Document 2, a simple flat plate 23 is used. For this reason, the space used in the front region of the upright column 11 is only the thickness of the flat plate 23, and a significant space saving can be achieved. The rail support beam 25 is welded to the flat plate 23 on the front surface 11a of the upright column 11, not from the inner back surface of the upright column, in particular, the portion protruding from the upright column 11 in the flat plate 23 as in the second aspect of Patent Document 2. Therefore, the welding work can be performed from the hoistway center side (front side of the upright column). Therefore, unlike the second aspect of Patent Document 2, there is no problem that it is difficult to see the welded portion that has entered the inside of the upright column and the welding work is difficult, and the workability is extremely good.

Embodiment 2. FIG.
As a second embodiment, an elevator rail fixing device according to the present invention will be described as a device for fixing a pair of car guide rails. FIG. 5 is a diagram of the same mode as FIG. 2 regarding the second embodiment. As also appearing in FIG. 1, the pair of car guide rails 7 are fixed by fixing one car guide rail 7 with one rail fixing device 121. Accordingly, the rail fixing device 121 according to the second embodiment is substantially the same as the rail fixing device 21 although the number and length of components are slightly different from the rail fixing device 21 according to the first embodiment.

  The rail fixing device 121 also includes a pair of flat plates 23, rail support beams 25, and rail bracket means 127. As FIG. 5 shows, a pair of flat plate 23 is provided similarly to the structure and attachment aspect of FIG. Since the rail support beam 125 is directed to support the single car guide rail 7, the rail support beam 125 is shorter than the rail support beam 25, but the configuration and the mounting manner are the same as those of the rail support beam 25. The rail bracket means 127 is constituted by a rail bracket 135. Although the rail bracket 135 is made of an L-shaped angle material and the direction of L is different, the rail bracket 135 is fixed to the rail support beam 125 by welding or the like, like the rail bracket 35.

  In the rail fixing device according to the second embodiment configured as described above, the car guide rail can be fixed in the same manner as in the first embodiment, while the device space can be made compact, and the rail fixing operation can be performed. An advantage that workability can be improved is obtained.

  Although the contents of the present invention have been specifically described with reference to the preferred embodiments, various modifications can be made by those skilled in the art based on the basic technical idea and teachings of the present invention. It is self-explanatory.
