CONSTITUTION: A rope(5) for driving an elevator is fixed to a ceiling(20) of an elevating passage(8). The rope(5) is hung on a counter weighter pulley(9) which is installed on the upper portion of the counter weighter(10) through a car pulley installed on the upper portion of a car through two pulleys(18,19) which is fixed to the upper portion of the elevating passage(8). The rope(5) is fixed to the ceiling(20) of the elevating passage(8) again. A disc-shaped small size winch(17) is integrally formed in the car pulley.

    The arrangement of traction machine for machine roomless elevator
    The present invention relates to a hoisting arrangement of an elevator without a machine room. In particular, in the case of 2: 1 roping, a hoisting arrangement for an elevator without a machine room of the hoisting machine is attached to a car pulley located at an upper portion of a car. It is about.
    In general, an electric elevator driven by a motor has a separate machine room in which a hoist including a motor is positioned above the hoistway.
    The existence of such a machine room is a burden in terms of building space utilization or design aspect, and the increase in building cost is also a considerable amount.
    Recently, in order to solve this problem, a small disk type hoist which has a sheave and a brake integrated by applying a synchronous motor has emerged, and an elevator has been introduced in which a disk type small hoist is placed and driven in a hoistway without a separate machine room.
    1 shows a typical example of a 2: 1 roping method for driving a car and a counter waiter when the hoist of an elevator is located in a separate machine room on top of a hoistway.
    The machine room 6, in which the hoist 2 and the driven sheave 7 are provided separately, is located at the upper part of the building, and the car 4 and the counter waiter 10 are provided in the hoistway 8 located at the lower part from the machine room 6. The pulleys 3 and 9 are located on top of each of the car 4 and the counter waiter 10.
    The car 4 and the counter waiter 10 are respectively connected to the compensation pulley 11 located below the hoistway 8 by a rope 50.
    Referring to the operation of the conventional device configured as described above are as follows.
    The rope 5 for driving the elevator has one end fixed to the ceiling 1 of the machine room 6, and the rope 5 passes through the car pulley 3 at the top of the car 4 and the machine room ( The hoisting sheave 2 in 6) is hooked to the counter waiter pulley 9 above the counter waiter 10 over the driven sheave 7 and again fixed to the ceiling 1 of the machine room 6. Accordingly, the car 4 is driven in the vertical direction by friction between the hoisting sheave 2 and the rope 5 as the motor in the hoisting machine rotates.
    According to the conventional elevator configured and operated as described above, since there is a separate machine room for driving the elevator, it causes a lot of restrictions in terms of construction, waste of space in design, building layout and unobserved aspects, and thus construction cost. Brings an increase.
    On the other hand, in the concept of an elevator without a machine room as shown in Figs. 2 and 3, one end of the rope 5 for driving the elevator is fixed to the ceiling 1, and the rope 5 is placed on both sides of the upper part of the car 4. The car pulleys 12 and 13 at the ends pass through the sheaves of the hoisting machine 2 fixed to the upper guide rail 15, and then hang on the counter waiter pulley 9 above the counter waiter 10 again to the ceiling (1). It is fixed at.
    Accordingly, the car 4 is driven in the vertical direction by friction between the hoisting sheave and the rope 5 as the motor in the hoisting machine 2 rotates. The car pulleys 12 and 13 at both ends of the upper portion of the car 4 are alternately arranged around the guide rail 15 as shown in FIG. 3 in order to balance while avoiding interference with the guide rollers.
    On the other hand, the prior art of an elevator without a machine room is an example of US Patent No. 5,429,211 and Japanese Patent Laid-Open No. 9-156855.
    According to the configuration as described above, because the hoist is located in the hoistway, the structure of the hoistway becomes complicated and the hoistway needs a space to be installed.
    The present invention has been made to solve the problems of the prior art as described above, by using a synchronous motor to reduce the size of the motor and accordingly by eliminating the reducer and by minimizing the sheaves and brakes by miniaturizing the hoist with the car upper pulley It is an object of the present invention to provide a hoisting arrangement for an elevator for driving an elevator without a separate machine room.
    In order to achieve the above object, the present invention, one end of the rope for driving the elevator to the ceiling of the hoistway, the rope through the car pulley installed on the top of the car two pulleys fixed to the top of the hoistway It is hooked to the counter-waiter pulley in the upper part of the counter-waiter, and it is fixed to the ceiling again, The said car pulley is characterized by integrating the disc-shaped small hoist.

    4 is a schematic configuration diagram of an elevator without a machine room of the present invention, and FIG. 5 is a plan view of FIG. 4.
    As shown, one end of the rope 5 for driving the elevator is fixed to the ceiling 20 of the hoistway 8, and the rope 5 is attached to the car pulley 13 installed on the upper part of the car 4. Via the two pulleys (18) and (19) fixed to the upper part of the hoistway (8) through the counter waiter pulley (9) installed at the upper part of the counter waiter (10) and fixed to the ceiling (20) of the hoistway (8) again. The disk pulley 17 is integrally formed with the car pulley 13.
    According to the present invention configured as described above, as the motor of the disk-type small hoist 17 is operated, the car pulley 13 connected thereto rotates so that the car 4 is rubbed by friction between the car pulley 13 and the rope 5. It will be driven in the vertical direction.
    As described above, the present invention installs a disk-type small hoist on the car side and integrates it with the car pulley, thus eliminating the need for a separate machine room as in the prior art, and eliminating space wastage in terms of construction and at the same time building layout and It can improve the aesthetics and reduce the construction cost.
