Definitions

  • the invention relates to an elevator system, wherein a member for supporting a hoisting machine disposed at a position close to the top within a hoistway is supported on an upper end section of counterweight rails which stand upright within the hoistway and guide ascending and descending operation of a counterweight.
  • Figs. 4 and 5 are views showing a conventional elevator system that is structurally analogous to an elevator system described in, e.g., JP-A-2000-318946 .
  • Fig. 4 is a longitudinal-cross-sectional view
  • Fig. 5 is a transverse cross-sectional view of the principal section of the elevator system shown in Fig. 4 .
  • Reference numeral 1 designates a hoistway for an elevator
  • 2 designates a car which ascends or descends within the hoistway 1
  • 3 designates car rails which stand upright within the hoistway 1, which are disposed on both sides of the car 2 when viewed in horizontally-projected perspective, and which guide ascending and descending operation of the car 2.
  • Reference numeral 4 designates rail brackets. One side of each rail bracket 4 is secured on a corresponding fixing member 5 formed from a beam constituting a side surface of the hoistway 1, and the other side of the rail bracket 4 is fastened to the corresponding car rail 3.
  • the rail brackets 4 are vertically spaced apart from each other within the hoistway 1.
  • Reference numeral 6 designates counterweight rails which stand upright within the hoistway 1 and are spaced apart from each other in a horizontal direction in the form of two lines. Of the two lines, one line is fastened to the rail brackets 4, and the other line is secured on the fixing members 5 and fastened to counterweight brackets 7 which are vertically spaced apart from each other within the hoistway 1.
  • the counterweight rails 6 guide ascending and descending operation of a counterweight 8, which is interposed between the two lines and moves vertically within the hoistway 1.
  • Reference numeral 12 designates a main rope.
  • One end of the main rope 12 is joined to the rope anchor arm 11.
  • the other end of the main rope 12 is passed around a car pulley 13 rotatably mounted on a lower section of the car 2. That end of the main rope 12 is then extended upward and passed around a drive sheave of the hoisting machine 9. That end is then extended downward and passed around a suspension pulley 14 of the counterweight 8 and joined to the support member 10.
  • the related-art elevator system is constructed in the previously-described manner.
  • the hoisting machine 9 When the hoisting machine 9 is operated, the car 2 and the counterweight 8 ascend and descend in opposite directions via the main rope 12.
  • Self weight of the hoisting machine 9 and load stemming from tension of the main rope 12 are supported by the car rails 3 by way of the rope anchor arm 11 and by the counterweight rails 6 by way of the support member 10.
  • the counterweight rails 6 require strength against the axial compressive force, as well as flexural strength which acts in a direction substantially perpendicular to the axis and is required to carry out a function of guiding the counterweight 8.
  • the rail brackets 4 and the counterweight brackets 7 are fastened to a framework material constituting floors of a building.
  • the rail brackets 4 and the other members are spaced at an interval equivalent to the height of each floor of the building.
  • the car rails 3 and the others are supported at intervals of three to four meters.
  • buckling will arise.
  • the size of the counterweight rails 6 must be increased in accordance with the support interval.
  • the invention is aimed at providing an elevator system which prevents occurrence of buckling, which would otherwise be caused when a support interval becomes excessively long, by use of counterweight rails of standard size in connection with a structure of compressive load acting on the counterweight rails for guiding ascending and descending operation of a counterweight.
  • JP 2000 044146 refers to a driving machinery supporting structure suitable for a steel frame building in a traction elevator having the driving machinery in an elevator shaft.
  • the upper ends of counterweight guides and building beam in the top most position of an elevator shaft are connected to one another by a machine base frame.
  • a machine frame for firmly supporting vertical load of driving machinery and an auxiliary member for supporting horizontal load are provided on the machine base frame.
  • JP 61-183379 U refers to an elevator system, in which one car guide rail is connected to a counterweight guide rail via a coupling member.
  • car rails for guiding ascending and descending operation of a car stand upright within a hoistway are provided.
  • a support member of a hoisting machine disposed at a position close to the top within the hoistway is supported on an upper end section of the counterweight rails.
  • the counterweight rails are fastened to rail brackets supporting the car rails.
  • a coupling member is interposed between the rail brackets which support the car rail and are spaced apart from each other in the vertical direction.
  • the car rail is fastened to one side of the coupling member, and the opposing counterweight rail is fastened to the other side of the same.
  • reference numeral 1 designates a hoistway for an elevator
  • 2 designates a car which ascends or descends within the hoistway 1
  • 3 designates car rails which stand upright within the hoistway 1, which are disposed on both sides of the car 2 when viewed in horizontally-projected perspective, and which guide ascending and descending operation of the car 2.
  • Reference numeral 4 designates rail brackets. One side of each rail bracket 4 is secured on a corresponding fixing member 5 formed from a beam constituting a side surface of the hoistway 1, and the other side of the rail bracket 4 is fastened to the corresponding car rail 3.
  • the rail brackets 4 are vertically spaced apart from each other within the hoistway 1.
  • Reference numeral 6 designates counterweight rails which stand upright within the hoistway 1 and are spaced apart from each other in a horizontal direction in the form of two lines. Of the two lines, one line is fastened to the rail brackets 4, and the other line is secured on the fixing members 5 and fastened to counterweight brackets 7 which are vertically spaced apart from each other within the hoistway 1.
  • the counterweight rails 6 guide ascending and descending operation of the counterweight 8 which is interposed between the two lines and moves vertically within the hoistway 1.
  • Reference numeral 12 designates a main rope.
  • a rope anchor 15 provided at one end of the main rope 12 is joined to the rope anchor arm 11.
  • the other end of the main rope 12 is passed around a car pulley 13 rotatably mounted on a lower section of the car 2. That end of the main rope 12 is then extended upward and passed around a drive sheave of the hoisting machine 9. The rope is then extended downward and passed around a suspension pulley 14 of the counterweight 8.
  • a rope anchor 16 provided at the other end of the rope 12 is joined to a position close to the counterweight rail 6 having the rail brackets 4 provided thereon.
  • Reference numeral 17 designates a coupling member. At least one coupling member 17 is disposed between the rail brackets 4 which are vertically spaced apart from each other.
  • the car rail 3 is fastened to one side of the coupling member 17 with a rail clip 18, a bolt 19 inserted into the edge of the coupling member 17, and a nut 20 screw-engaged with an insertion end of the bolt 19.
  • the other end of the coupling member 17 is fastened to the counterweight rail 6 opposing the coupling member 17, with a rail clip 21, a bolt 22 inserted into the edge of the coupling member 17, and a nut 23 screw-engaged with an insertion end of the bolt 22.
  • the coupling member 17 is disposed at least one location between the rail brackets 14 that are spaced apart from each other in the vertical direction, whereby the car rail 3 is coupled to the counterweight rail 6.
  • the counterweight rails 6 can be reduced in size to rails of standard size without involvement of complicated efforts, thereby curtailing costs for constructing the elevator system.
  • the car rail 3 and the counterweight rail 6 are fastened to the coupling member 17 by way of the rail clips 18, 21. Accordingly, the car rail 3 and the counterweight rail 6 can be readily coupled together by means of the coupling member 17 at any appropriate location with respect to the vertical direction. In order to limit, to a predetermined value, the amount of displacement developing in the counterweight rail 6 in the direction orthogonal to the axis, the coupling members 17 can be readily increased to an appropriate number.
  • Measures can be readily taken against the amount of displacement developing in the counterweight rail 6 in the direction orthogonal to the axis, the amount differing from one elevator to another elevator. Hence, occurrence of displacement in the counterweight rail 6 in the direction orthogonal to the axis can be prevented through simple operation.
  • the rope anchor 16 of the main rope 12 opposing the counterweight 8 is located at a position close to the edge of the support member 10 facing the counterweight rail 6 joined to the coupling member 17.
  • the majority of the vertical load acting on the rope anchor 16 is supported by the counterweight rail 6 fastened to the coupling member 17.
  • Displacement, which develops from the load of the rope anchor 16 in the counterweight rail 6 close to the coupling member 17 in the direction orthogonal to the axis, is transmitted to and supported by the car rail 3 by way of the coupling member 17.
  • the strength of the counterweight rail 6 provided close to the coupling member 17 can be made close to the strength required to carry out a function of guiding the counterweight 8.
  • the counterweight rail 6 can be reduced to a rail of standard size, thereby curtailing costs for constructing the elevator system.
  • an elevator system of the invention when a building where the elevator system is to be installed employs, for a framework formed by assembly of steel products, a flexible structure provided with wall material into which anchor bolts cannot be fastened upright, rail brackets are fastened to the framework material constituting floors of the building.
  • a support member for the hoisting machine disposed at a position close to the top within the hoistway is supported at an upper end section of the counterweight rails which stand upright within the hoistway and guide ascending and descending operation of the counterweight.
  • the counterweight rail is coupled to the car rail by means of a coupling member provided between rail brackets, the brackets being spaced apart from each other in the vertical direction and fastening the car rail to a fixing member of the hoistway.
  • a coupling member provided between rail brackets, the brackets being spaced apart from each other in the vertical direction and fastening the car rail to a fixing member of the hoistway.
