Definitions

  • the present invention relates to an elevator guide rail supporting device and, more particularly, to the miniaturization of a counterweight-side guide rail supporting device.
  • the machine room-less elevator is becoming the mainstream of elevators.
  • the equipment configuration of elevators does not change greatly as compared with the elevator with a machine room. Therefore, in order to reduce the plane dimension of shaft in the configuration of the present machine room-less elevator, it is also indispensable to make equipment other than the traction machine and the control panel small and thin.
  • an elevator guide rail that is erected in the shaft to guide the up-and-down movement of a cab and a counterweight is generally configured as described below.
  • a rail-side bracket 2 is brought into contact with the back surface of a guide rail 1 having a T-shaped cross section, rail clips 3 are pressed against a flange portion 1a on the shaft wall side and a flange portion 1b on the cab side of the guide rail 1, and the guide rail 1 is fixed by a fastening part consisting of a bolt 5 and a nut 6.
  • reference numeral 7 denotes a wall-side bracket for fixing the guide rail 1 to a shaft wall 8
  • 9 denotes the cab of the elevator.
  • the arrangement position of the guide rail 1 is determined by a clearance between the cab 9 and the rail-side bracket 2 of the counterweight-side guide rail 1 depending on the width of the counterweight.
  • the counterweight-side guide rail 1 can be arranged so as to be close to the cab 9 side, so that the plane dimension of the shaft can be reduced.
  • a guide rail supporting device which includes a base part that is in contact with the bottom surface of a bottom flange of a guide rail, a folding back piece that is provided integral with the base part and elastically holds one side part of the bottom flange of the guide rail, and a rail clip that is fastened to the base part via a bolt to press the other side part of the bottom flange of the guide rail toward the base part, and elastically holds one side part of the bottom flange of the guide rail between the base part and the folding back piece and holds the other side part of the bottom flange of the guide rail by means of the rail clip and the base part (for example, refer to Patent Document 1).
  • an elevator guide rail supporting device has been known which uses an L-shaped rail clip so that the projection amount of the rail clip from the guide rail side face is reduced and the interference with other equipment in the shaft is prevented (for example, refer to Patent Document 2).
  • Patent Document 1 since the flange of the guide rail is elastically held by a folding back part of the base part, the base part itself must be handled when the guide rail is installed. Because the base part supports the guide rail, the base part is required to have a high strength and hence must be relatively heavy, which poses a problem of poor workability. Also, since the flange of the guide rail is elastically held by the folding back part of the base part, the work for fitting the folding back part on the flange of the guide rail provided in the height direction in a limited space of the shaft is not easy.
  • the present invention has been made to solve the above problems, and accordingly an object thereof is to provide an elevator guide rail supporting device in which the mounting dimension of a rail-side bracket is decreased and hence the plane dimension of an elevator shaft is decreased by changing the construction of a rail clip.
  • the present invention provides an elevator guide rail supporting device including an elevator guide rail which is erected in an elevator shaft to guide the up-and-down movement of a cab and a counterweight; a rail-side bracket for fixing the guide rail to a shaft wall; and clips for attaching and fixing flange portions at both sides of the guide rail to the rail-side bracket, characterized in that the elevator guide rail supporting device includes a first rail clip which is provided on the back surface side of the rail-side bracket and is provided with a hook portion at the tip end thereof, the hook portion attaching a cab-side flange portion of the guide rail and the rail-side bracket to each other in such a manner as to hold the two elements by means of the first rail clip; and a second rail clip for fasteningly fixing a shaft wall-side flange portion of the guide rail to the rail-side bracket together with the first rail clip in the end portion on the side opposite to the hook portion at the tip end of the first rail clip.
  • the first rail clip has a frictional holding force increased by pressing the back surface of the guide rail using a bolt and nut at a place on the hook portion side at the tip end thereof.
  • a plurality of second rail clips are installed in the up and down direction in the end portion on the side opposite to the hook portion at the tip end of the first rail clip.
  • the first rail clip has a frictional holding force increased by pressing the back surface of the guide rail using a plurality of bolts and nuts at a place on the hook portion side at the tip end thereof.
  • a jack bolt is provided in the shaft-side end portion of the rail-side bracket, and a bolt bearer which bears the tip end portion of the jack bolt is provided in the end portion on the side opposite to the hook portion at the tip end of the first rail clip.
  • the elevator guide rail supporting device is used for a counterweight-side guide rail.
  • the counterweight-side guide rail can be moved offsetly to the cab side, so that the plane dimension of the shaft can be decreased by the offset amount.
  • the plane (transverse) dimension X of the rail-side bracket portion necessary for fixing the guide rail is smaller than the case where two second rail clips having the conventional construction are used, so that the counterweight-side guide rail can be moved offsetly to the cab side.
  • the plane dimension of the shaft can be decreased by the offset amount.
  • Figure 3 is a partial plan view of the elevator shaft, showing an elevator guide rail supporting device of embodiment 2 in accordance with the present invention.
  • an internal thread is formed in the rail-side bracket 2
  • a bolt 10 and a nut 11 are supported by the internal thread portion from the back surface of the counterweight-side guide rail 1
  • the first rail clip 4 is pressed by the bolt 10 and the nut 11 to increase the frictional holding force of the attachment surface between the first rail clip 4 and the rail-side bracket 2.
  • the construction is such that the first rail clip 4 is pressed by the bolt 10 and the nut 11, the work for fitting the first rail clip 4 on the flange portion 1b is relatively easy, and the first rail clip 4 can be fixed more surely by the bolt and nut.
  • FIG 4 is a partial plan view of the elevator shaft, showing an elevator guide rail supporting device of embodiment 3 in accordance with the present invention.
  • a jack bolt 12 is installed in the end portion on the shaft wall 8 side of the rail-side bracket 2, and a bolt bearer 4a that bears the tip end portion of the jack bolt 12 is bendingly formed in the end portion on the side opposite to the U-shaped portion at the tip end of the first rail clip 4.
  • the bolt bearer 4a in the end portion on the side opposite to the U-shaped portion at the tip end of the first rail clip 4 is pressed by the jack bolt 12, by which the holding force of the first rail clip 4 is increased.
  • the plane (transverse) dimension X of the rail-side bracket portion necessary for fixing the guide rail is small, and by offsetly moving the counterweight-side guide rail to the cab side, the plane dimension of the shaft can be decreased by the offset amount.
