Definitions

  • the present invention relates to an elevator car frame that supports a cage.
  • the present invention aims to solve the above problems and an object of the present invention is to provide an elevator car frame that can suppress car vibrational amplitude more reliably and that can also suppress increases in manufacturing costs.
  • an elevator car frame characterized in including: a car frame main body that supports a cage, the car frame main body having an upright that faces a guide rail that guides a car; an intermediate stopper that is disposed on an intermediate portion of the upright, and that is disposed between the guide rail and the upright; a vibration damping member that has a predetermined vibration damping capacity, the vibration damping member being fixed to the upright so as to be parallel to a longitudinal direction of the upright; and a reinforcing member that has higher rigidity than the vibration damping member, the reinforcing member holding the vibration damping member against the upright, and being fixed to the vibration damping member.
  • the intermediate stopper is disposed on the intermediate portion of the upright, and the vibration damping member, which has a predetermined vibration damping capacity, is fixed to the upright, and the reinforcing member is also fixed to the vibration damping member, even if the car is vibrated horizontally by an earthquake, for example, increases in the vibrational amplitude of the car can be suppressed by the intermediate stopper contacting the guide rail. If the intermediate stopper contacts the guide rail, and the upright is flexed, because shearing deformation arises in the vibration damping member, the vibration damping member can be made to exhibit its vibration damping function, enabling horizontal vibration of the car to be damped effectively. From this, car vibrational amplitude can be suppressed more reliably. Because the intermediate stopper and the vibration damping member are fixed to the upright, and the reinforcing member is simply fixed to the vibration damping member, increases in manufacturing costs can also be suppressed.

  • Figure 2 is a cross section along a horizontal plane II in Figure 1 .
  • first and second guide rails 2 and 3 that are disposed so as to be parallel to a vertical direction are installed inside a hoistway.

  • the car 1 has: a cage 6 in which passengers ride; and a car frame 7 that supports the cage 6. As shown in Figure 1 , the cage 6 is surrounded by a car frame main body 8 that is included in the car frame 7.
  • the car frame main body 8 has: a lower frame 9 that is disposed horizontally below the cage 6; an upper frame 10 that is disposed above the cage 6, and that is parallel to the lower frame 9; and first and second uprights 11 and 12 that connect the two end portions of the lower frame 9 and the upper frame 10.
  • the cage 6 is placed on top of the lower frame 9.
  • the cage 6 is also disposed between the first upright 11 and the second upright 12 in a horizontal direction.
  • the first upright 11 is disposed vertically facing the first guide rail 2.
  • the upright groove 11a is disposed on the first upright 11 parallel to a longitudinal direction of the first upright 11.
  • the first upright 11 is disposed between the cage 6 and the first guide rail 2 such that the upright groove 11a faces toward the first guide rail 2.
  • the second upright 12 is disposed vertically facing the second guide rail 3.
  • the upright groove 12a is disposed on the second upright 12 parallel to a longitudinal direction of the second upright 12.
  • the second upright 12 is disposed between the cage 6 and the second guide rail 3 such that the upright groove 12a faces toward the second guide rail 3.

  • a guiding groove 16 into which a portion of the second guide rail 3 is inserted is disposed on each of the guiding apparatuses 15.
  • the respective guiding apparatuses 13 and 15 are guided by the respective guide rails 2 and 3 in a state in which a portion of the first guide rail 2 is inserted into each of the guiding grooves 14, and a portion of the second guide rail 3 is inserted into each of the guiding grooves 16.
  • a tabular intermediate stopper 17 that protrudes outward from the first upright 11 is disposed on an intermediate portion of the upright 11 so as to face toward the first guide rail 2.
  • the intermediate stopper 17 is disposed at a position at which distances from the respective guiding apparatuses 13 that are mounted to the upper end portion and the lower end portion of the first upright 11 are equal (a central position of the upright 11).
  • the intermediate stopper 17 is fixed horizontally inside the upright groove 11a.

  • a notch portion 20 is disposed on the intermediate stopper 19. A portion of the second guide rail 3 is inserted inside the notch portion 20 so as to have a clearance interposed.
  • a pair of vibration damping members 21 are fixed to the first upright 11 so as to be parallel to the longitudinal direction of the first upright 11.
  • the respective vibration damping members 21 are members that have a higher vibration damping capacity than the first upright 11 (a predetermined vibration damping capacity).
  • a rubber, or a plastic, for example, can be used as a material that constitutes the respective vibration damping members 21.
  • the first upright 11 is held between the respective vibration damping members 21 in a direction (a width direction of the upright 11) that is perpendicular to a common plane that includes both of the uprights 11 and 12 (a vertical plane that is parallel to the width direction of the car 1). Lengths of the respective vibration damping members 21 are shorter than the length of the first upright 11.
  • the intermediate stopper 17 is disposed within the length of the respective vibration damping members 21.
  • Respective reinforcing members 22 that have higher rigidity than the vibration damping members 21 are fixed to the respective vibration damping members 21 so as to be parallel to the longitudinal direction of the vibration damping members 21.
  • Iron for example, can be used as a material that constitutes the reinforcing members 22.
  • the reinforcing members 22 are rod-shaped members that have a rectangular cross sectional shape.
  • the respective reinforcing members 22 hold the vibration damping members 21 against the first upright 11.
  • the first upright 11 and the respective vibration damping members 21 are thereby held together in the width direction of the upright 11 by the respective reinforcing members 22.
  • Lengths of the respective reinforcing members 22 are similar to the lengths of the vibration damping members 21.
  • the vibration damping members 21 and the reinforcing members 22 are disposed on the first upright 11 as described below. Specifically, the reinforcing members 22 are supported so as to be separated by a predetermined clearance from the first upright 11, and then spaces between the first upright 11 and the reinforcing members 22 are surrounded by a molding frame, and the material for the vibration damping members 21 is poured into the spaces that are surrounded by the molding frame.
  • the vibration damping members 21 and the reinforcing members 22 are disposed on the first upright 11 by hardening the material that is poured into the spaces as the vibration damping members 21. Moreover, in this example, fixing of the vibration damping members 21 onto both the first upright 11 and the reinforcing members 22 is performed by vulcanizing adhesion.
  • a pair of vibration damping members 23 are fixed to the second upright 12, and reinforcing members 24 are respectively fixed to each of the vibration damping members 23.
  • the material that constitutes the respective vibration damping members 23 is similar to the material that constitutes the above vibration damping members 21.
  • the material that constitutes the respective reinforcing members 24 is similar to the material that constitutes the above reinforcing members 22.
  • the fixing positions and method for fixing the vibration damping members 23 onto the second upright 12 are similar to the fixing positions and method for fixing the vibration damping members 21 onto the first upright 11.
  • the fixing positions and method for fixing the reinforcing members 24 onto the vibration damping members 23 are similar to the fixing positions and method for fixing the reinforcing members 22 onto the vibration damping members 21.
  • the car frame 7 includes the car frame main body 8, the respective intermediate stoppers 17 and 19, the respective vibration damping members 21 and 23, and the respective reinforcing members 22 and 24.
  • Figure 3 is a partially cutaway side elevation that shows a state when the car 1 from Figure 1 vibrates horizontally inside a hoistway.
  • Figure 4 is a horizontal cross section that shows an elevator apparatus from Figure 3 .
  • the car 1 passes through the position of the each of the rail brackets 4 while being moved. Consequently, the positions of the respective guiding apparatuses 13 and 15 relative to the rail brackets 4 change together with the movement of the car 1.
  • the first guide rail 2 is subjected to horizontal forces from the respective guiding apparatuses 13.
  • the first guide rail 2 flexes at the positions of the respective guiding apparatuses 13.
  • the positions of the rail brackets 4 are approximately central height positions between the respective guiding apparatuses 13
  • deflection of the first guide rail 2 at the positions of the respective guiding apparatuses 13 is large because the distances between the positions of the respective guiding apparatuses 13 and the positions of the rail brackets 4 are great.
  • the intermediate stopper 17 contacts the first guide rail 2.
  • the first guide rail 2 is thereby subjected to the horizontal force from the intermediate stopper 17.
  • a rail bracket 4 is present at a position that is approximately level with the height position of the intermediate stopper 17, the first guide rail 2 is less likely to flex at the position of the intermediate stopper 17, making the first upright 11 flex instead due to a reaction force that acts on the intermediate stopper 17.
  • dimensions of the intermediate stopper 17 are adjusted such that the respective guiding apparatuses 15 are not disengaged from the second guide rail 3 when the first upright 11 is flexed.
  • the respective vibration damping members 21 are subjected to shearing deformation while remaining fixed to the reinforcing members 22. As the respective vibration damping members 21 are subjected to the shearing deformation, horizontal vibration of the car 1 is damped by the vibration damping function of the respective vibration damping members 21.
  • Figure 5 is a horizontal cross section that shows a state in which the intermediate stopper 19 contacts the second guide rail 3 from Figure 4 . Even if the car 1 vibrates toward the second guide rail 3, and the intermediate stopper 19 contacts the second guide rail 3, horizontal vibration of the car 1 is damped by the vibration damping function of the respective vibration damping members 23 in a similar manner to the above case in which the car 1 vibrated toward the first guide rail 2. Moreover, dimensions of the intermediate stopper 19 are also adjusted such that the respective guiding apparatuses 13 are not disengaged from the first guide rail 2 when the second upright 12 is flexed.
  • the vibration damping members 21 and 23 can be made to exhibit their vibration damping function, enabling horizontal vibration of the car 1 to be damped effectively. From this, car vibrational amplitude can be suppressed more reliably, enabling the guiding apparatuses 13 and 15 to be prevented from disengaging from the guide rails 2 and 3. Because the intermediate stoppers 17 and 19 and the vibration damping members 21 and 23 are fixed to the uprights 11 and 12, and the reinforcing members 22 and 24 are simply fixed to the vibration damping members 21 and 23, increases in manufacturing costs can also be suppressed.
  • notch portions 18 and 20 into which portions of the guide rails 2 and 3 are inserted so as to have a clearance interposed are disposed on the intermediate stoppers 17 and 19, not only vibration of the car 1 in the width direction of the hoistway, but also vibration of the car 1 in a depth direction of the hoistway can be suppressed effectively.
  • Figure 6 is a perspective that shows an elevator car according to Embodiment 2 of the present invention.
  • Figure 7 is a cross section along a horizontal plane VII in Figure 6 .
  • a plurality of (in this example, four) fastening apparatuses 31 that restrict positions of vibration damping members 21 and reinforcing members 22 relative to a first upright 11 are disposed on the first upright 11.

  • the respective fastening apparatuses 32 are disposed at predetermined positions in the longitudinal direction of the second upright 12.
  • the fastening apparatuses 32 are respectively disposed at a position at which a distance from a guiding apparatus 15 that is mounted to an upper end portion of the upright 12 and a distance from an intermediate stopper 19 are equal, and at a position at which a distance from a guiding apparatus 15 that is mounted to a lower end portion of the upright 12 and a distance from the intermediate stopper 19 are equal.
  • the fastening apparatuses 31 have: a bolt 33; and a nut 34 that is screwed together with the bolt 33.
  • the bolt 33 is passed sequentially through the reinforcing member 22, the vibration damping member 21, and the first upright 11, and protrudes outward inside an upright groove 11 a.
  • the nut 34 is screwed together with the bolt 33 inside the upright groove 11 a.
  • the reinforcing member 22, the vibration damping member 21, and the first upright 11 are fastened between a head portion of the bolt 33 and the nut 34.
  • the fastening apparatuses 32 have: a bolt 35; and a nut 36 that is screwed together with the bolt 35.
  • the bolt 35 is passed sequentially through the reinforcing member 24, the vibration damping member 23, and the second upright 12, and protrudes outward inside an upright groove 12a.
