Definitions
- the present invention relates to an elevator in which a hoisting machine for raising and lowering a car and a counterweight is mounted to the counterweight.
- FIG 3 is a perspective of a conventional elevator shown in International Publication No. WO 00/53520 (Pamphlet).
- the elevator includes: a car 1 ascending and descending inside a hoistway; a counterweight 5 ascending and descending inside the hoistway interdependently with the car 1; a rope 3 by which the car 1 and the counterweight 5 are suspended inside the hoistway; a hoisting machine 10 mounted to the counterweight 5 for raising and lowering the car 1 and the counterweight 5 by the rope 3; and a control apparatus 11 mounted to the counterweight 5 for controlling driving of the hoisting machine 10.
- the car 1 is guided so as to be movable in a vertical direction of the hoistway by means of car rails 7 extending in the vertical direction and guide shoes (not shown) and guide rollers (not shown) disposed on sides of the car 1 near the car rails 7.
- the counterweight 5 is also similarly guided so as to be movable in a vertical direction of the hoistway by means of guide rails 8 extending in the vertical direction and rollers 9.
- the rope 3 has one end portion fixed to a hoistway ceiling, and is suspended on top portion pulleys 4 by means of a pulley 2 fixed to a bottom surface of the car 1.
- the rope 3 also suspends an upper portion pulley 6 on the counterweight 5, and an end portion thereof is fixed to the hoistway ceiling.
- one of the rollers 9 contacting the guide rails 8 is connected to the hoisting machine 10, and the counterweight 5, the hoisting machine 10, and the control apparatus 11 are moved in the vertical direction by rotating the roller 9 by driving the hoisting machine 10, and the car 1 is also moved in an opposite direction together with that movement.
- the hoisting machine 10 is mounted to the counterweight 5, and the hoisting machine 10 itself serves part of the function of the counterweight 5, but one problem has been that a special hoisting machine 10 answering to specifications such as capacity, speed, etc., of the car 1 must be mounted to the counterweight 5.
- WO99/43592 discloses features falling under the preamble of Claim 1. US 6,085,874 is further prior art.
- the present invention aims to solve the above problems and an object of the present invention is to provide an elevator not necessarily requiring a hoisting machine specifically for a given set of elevator specification modifications such as capacity, speed, etc., of a car.
- Another object of the present invention is to provide an elevator enabling a rope that is optimum for a car and for a hoisting machine to be selected by providing a separate rope for each.
- an elevator having the features of Claim 1.
- Figure 1 is a structural diagram of an elevator according to Embodiment 1 of the present invention.
- This elevator includes: a car 1 ascending and descending inside a hoistway; a counterweight 20 ascending and descending inside the hoistway interdependently with the car 1; two hoisting machines 22a and 22b mounted to the counterweight 20; a control apparatus 11 mounted to the hoisting machines 22a and 22b for controlling driving of the hoisting machines 22a and 22b; a car rope 21 having one end portion connected to the car 1, and another end portion connected to the control apparatus 11 via a suspension sheave 23 and a return sheave 24; and hoisting machine ropes 27a and 27b each having an upper end portion connected to a ceiling of the hoistway by means of a tension controller 26, a lower end portion connected to a floor surface of the hoistway, and an intermediate portion wound onto a respective hoisting machine 22a or 22b.
- the hoisting machines 22a and 22b have identical specifications. Furthermore, the counterweight 20, the hoisting machines 22a and 22b, and the control apparatus 11 are already integrated before installation in the elevator, in other words, before shipping from a factory, and constitute a counterweight main body 25.
- the hoisting machines 22a and 22b fit inside an external shape of the counterweight 22 when viewed along an extended line of the hoistway.
- the hoisting machine ropes 27a and 27b are ropes made of a resin, or ropes coated with a resin, are flexible, and can be wound 360 degrees around the hoisting machines 22a and 22b, and constant tension is always provided in the hoisting machine ropes 27a and 27b by the tension controllers 26, even against age-related stretching, vibration, etc.
- hoisting machines 22a and 22b are identical to each other (in shape, dimensions, and output), installation work and parts management are simplified, and maintenance is also facilitated.
- the hoisting machine ropes 27a and 27b and the car rope 21 are separate, enabling ropes that are optimum for their respective operating conditions to be selected, and the loads on the ropes 27a and 27b and the car rope 21 are reduced proportionately, enabling extended service life, and also there is no need to replace all of the ropes together, making it sufficient that only ropes requiring replacement be replaced.
- tension controllers 26 for disposing the hoisting machine ropes 27a and 27b under tension are fixed to the ceiling, and tension in the hoisting machine ropes 27a and 27b is adjusted by these tension controllers 26 so as to be always constant, the hoisting machine ropes 27a and 27b are prevented from dislodging from the hoisting machines 22a and 22b in an axial direction during driving of the hoisting machines 22a and 22b, etc., reliably transmitting driving force from the hoisting machines 22a and 22b as hoisting force to the counterweight main body 25 and the car 1.
- the hoisting machine ropes 27a and 27b are flexible ropes, the hoisting machine ropes 27a and 27b can be simply wound around the hoisting machines 22a and 22b, which have a small radius of curvature.
- the hoisting machines 22a and 22b have external dimensions that fit inside the external shape of the counterweight 20 when viewed along an extended line of the hoistway, it is not necessary to increase horizontal surface area for the hoisting machines 22a and 22b.
- the counterweight 20 and the hoisting machines 22a and 22b may also be integrated in advance before installation, and the hoisting machines 22a and 22b and the control apparatus 11 may also be integrated.
- an elevator was explained in which two hoisting machines 22a and 22b are mounted to the counterweight 20, and a car rope 21 and hoisting machine ropes 27a and 27b are provided, but a plurality of hoisting machines may also be mounted to a counterweight in an elevator in which a car and the counterweight are suspended by a single rope.
- a car may also be suspended by a car rope, and a hoisting machine suspended by a hoisting machine rope, in an elevator in which one hoisting machine is mounted to a counterweight.
- End portions of the hoisting machine ropes may also be fixed directly onto the hoistway ceiling.
- control apparatus 11 is mounted to the counterweight 20, but the present invention can of course be applied to an elevator in which the control apparatus 11 is not mounted to a counterweight.
- the present invention is useful in an elevator in which a hoisting machine is mounted to a counterweight due to the fact that it is not necessary to provide a hoisting machine having special specifications.
