Definitions

  • This invention relates to an elevator not equipped with a counterweight.
  • a so-called slewing elevator in which a car is suspended at one end of a rope wound around a hoist and a counterweight is suspended at the other end of the rope, is commonly used.
  • a vine elevator the tension applied to the ropes on both sides of the hoisting machine is almost balanced, and the hoisting machine can raise and lower the car with a relatively small torque.
  • the lift type elevator it is necessary to dispose the counterweight from the lift path of the car, and there is a problem that the lift path area is widened.
  • the lever is swingably attached to the back side of the car with the shaft as a fulcrum, the upper fixed pulley is disposed at the upper part of the hoistway, and the lower fixed pulley is the hoistway. It was arranged at the bottom. Furthermore, the upper and lower moving pulleys were attached to the side surface of the car, and the hoisting machine was disposed above the upper moving pulley. Then, the rope attached to the upper surface side of the lever at one end side is wound around the hoist after passing through the upper fixed pulley and the upper movable pulley, and the rope attached to the lower surface side of the lever at the other end side. It was wound around the hoist after passing through the lower fixed pulley and the lower movable pulley. The lever swings around the axis to absorb the elongation due to aging of the rope.
  • the present invention has been made to solve the above-described problems, eliminates the need for a lever for absorbing the elongation due to aging of the counterweight and the rope, increases the effective space in the hoistway, and uses a simple mechanism.
  • the purpose is to obtain an elevator that can absorb the elongation due to aging of the rope.
  • the elevator according to the present invention is arranged in the elevator car that can be moved up and down in the hoistway, the upper car pulley that is arranged in the car, the upward tension acts, and the car.
  • the amount of rope that passes through the upper car pulley matches the amount of rope that passes through the lower car pulley. Therefore, regardless of whether the car is raised or lowered, The vertical position is maintained. Therefore, a lifting / lowering path for the tension weight extending in the vertical direction is not necessary, and an effective space can be expanded in the lifting / lowering path. Further, since the elongation due to the aging of the rope can be absorbed by the tension weight or the lowering of the car, a mechanism for absorbing the elongation due to the aging of the rope can be realized with a simple configuration. Furthermore, a lever that absorbs the elongation due to the aging of the rope becomes unnecessary, and the effective space in the hoistway can be further expanded.
