Definitions

  • the present invention relates to a rail mounting device for an elevator which is used to mount a guide rail for guiding a member to be raised and lowered by the elevator onto an inner wall surface of a hoistway.
  • a plurality of guide rails are often installed in a hoistway to guide a car and a counterweight.
  • Each guide rail is fixed in place in the hoistway by means of a fixing bracket.
  • Japanese Utility Model Application Laid-open No. Hei 4-56179 discloses a reinforcing member arranged in the hoistway separately from the fixing bracket in order to reinforce the fixation of the guide rail. With respect to one inner wall surface to which the fixing bracket is fixed, the reinforcing member is fixed to the other inner wall surface perpendicular to the one inner wall surface. Further, the reinforcing member is arranged offset in the height direction with respect to the fixing bracket.
  • Japanese Utility Model Application Laid-open No. Sho 55-11994 discloses a guide rail fitting that can be adjusted in its position with respect to the horizontal direction of the guide rail.
  • the guide rail fixing fitting has a wall-side fitting fixed to an inner wall surface of the hoistway, and a rail-side fitting that is mounted to the wall-side fitting and can be adjusted in its position with respect to the wall-side fitting.
  • the rail-side fitting has a vertical portion arranged in parallel to the inner wall surface of the hoistway, and a horizontal portion extending from a lower edge portion of the vertical portion toward the hoistway inner wall surface side (rear surface side of the vertical portion).
  • the horizontal portion is provided with an elongated hole through which a mounting bolt for mounting the rail-side fitting to the wall-side fitting is passed.
  • the positional adjustment of the rail-side fitting with respect to the wall-side fitting can be effected through the positional adjustment of the mounting bolt with respect to the elongated hole.
  • the reinforcing member is formed separately from the fixing bracket, so it is necessary to mount the fixing bracket and the reinforcing member one by one to the inner wall surface of the hoistway, making the installation of the guide rail in the hoistway rather troublesome.
  • the horizontal portion of the rail-side fitting is arranged on the rear surface side of the vertical portion. Accordingly, the inner wall surface of the hoistway and the vertical portion interfere with the mounting of the rail-side fitting to the wall-side fitting with the mounting bolt, making the fastening of the mounting bolt rather troublesome.
  • the present invention has been made with a view to solving the above-mentioned problems, and it is therefore an object of the invention to provide a rail mounting device for an elevator which is capable of reducing the time and trouble required for installing a guide rail in a hoistway.
  • a rail mounting device for an elevator for mounting a guide rail for guiding a member to be raised and lowered by the elevator onto a first inner wall surface and a second inner wall surface of a hoistway, which are adjacent to each other, according to the present invention includes a bracket member having: a first wall-fixing portion fixed to the first inner wall surface; a second wall-fixing portion fixed to the second inner wall surface; and a mounting portion to which the guide rail is mounted, the first wall-fixing portion, the second wall-fixing portion, and the mounting portion being integrated with one another.
  • Fig. 1 is a horizontal sectional view showing a part of an elevator according to Embodiment 1 of the present invention. Referring to Fig. 1 , a pair of car guide rails (not shown) and a pair of counterweight guide rails 2 are installed in a hoistway
  • Each counterweight guide rail 2 has a rail main body 7 including a rear surface 6 opposed to the second inner wall surface 5, and a guide portion 8 protruding toward the counterweight 3 from the rail main body 7 and serving to guide the counterweight 3. Further, each counterweight guide rail 2 is mounted to the first and second inner wall surfaces 4, 5 through the intermediation of a rail mounting device for an elevator (hereinafter, simply referred to as the "rail mounting device") 9.
  • a rail mounting device for an elevator hereinafter, simply referred to as the "rail mounting device" 9.
  • Fig. 2 is a perspective view showing the rail mounting device 9 for an elevator shown in Fig. 1 .
  • the rail mounting device 9 has a bracket member 10 which is fixed to each of the first and second inner walls 4 , 5 and to which the counterweight guide rail 2 is mounted.
  • bracket member 10 is prepared by bending a single metal plate. That is, the horizontal portion 11, the first wall-fixing portion 12, the second wall-fixing portion 13, and the mounting portion 14 are formed integrally by the same member.
  • the first wall-fixing portion 12 is provided with a vertically extending elongated hole 15, and the second wall-fixing portion 13 is provided with a horizontally extending elongated hole 16. Further, the mounting portion 14 is provided with a pair of bolt passage holes 17 that are arranged at a spacing larger than the width of the rail main body 7.
  • An anchor bolt (not shown) for fixing the first wall-fixing portion 12 to the first inner wall surface 4 is passed through the elongated hole 15. Further, an anchor bolt (not shown) for fixing the second wall-fixing portion 13 to the second inner wall surface 5 is passed through the elongated hole 16. Further, passed through each of the bolt passage holes 17 is a bolt (not shown) for fixing a pair of rail clips (not shown), which abut the both side portions of the rail main body 7, to the mounting portion 14 .
  • the counterweight guide rail 2 is mounted to the mounting portion 14 through the fixation of the rail clips to the mounting portion 14.
  • each first wall-fixing portion 12 and each second wall-fixing portion 13 are fixed to the first inner wall surface 4 and the second inner wall surface 5, respectively, with the anchor bolts.
  • each counterweight guide rail 2 is installed in the hoistway 1.
  • the first wall-fixing portion 12, the second wall-fixing portion 13, and the mounting portion 14 are integrated with one other. Accordingly, the positioning of the bracket member 10 with respect to the first inner wall surface 4 and the second inner wall surface 5, which are different from each other, can be performed at the same time, whereby the installation of the rail mounting device 9 in the hoistway 1 can be performed in a short time and with ease. Therefore, it is possible to reduce the time and trouble required for the installation of the counterweight guide rail 2 in the hoistway 1. Further, the first wall-fixing portion 12, the second wall-fixing portion 13, and the mounting portion 14 are integrated with one other, whereby the number of parts can be reduced to achieve a reduction in the manufacturing cost of the rail mounting device 9.
  • first wall-fixing portion 12, second wall-fixing portion 13, and mounting portion 14 enables compactness of the rail mounting device 9, whereby the first and second inner wall surfaces 4, 5 can be arranged close to the counterweight guide rail 2 to thereby achieve a reduction in the space required inside the hoistway 1.
  • the mounting portion 14 may be provided directly on the second inner-wall fixing portion 13.
  • the second inner wall surface 5 can be brought even closer to the counterweight guide rail 2, thereby enabling a further reduction in the space required inside the hoistway 1.
  • the first wall-fixing portion 12 is provided to the first inner wall surface 4 side end portion of the second wall-fixing portion 13.
  • the second inner wall surface 5 is provided with a dent for preventing the bolt passed through each bolt passage hole 17 from interfering with the second inner wall surface 5.
