Abstract

PURPOSE: A method for roping of an elevator is provided to drive the elevator without a separate machine room by arranging a slimming winch inside an elevating road with using a driving motor and integrating a sheave and a brake. CONSTITUTION: A pulley of car side(13) is installed in upper both sides of a car(4) and a sheave(12) and a motor(17) are installed in the upside of a guide rail(15). The one side of a rope is fixed in a ceiling(1) of an elevating road by hanging the other side of the rope fixed in the ceiling of the elevating road in the pulley of car side(13), the sheave(12) and a counter weight pulley(9). The height of a rope fixing unit(1) with the car(4) is changed by driving the rope(5) with the sheave when a motor(17) is driven toward one side. The higher the position of the car(4) is, the lower the counter weight(10) is, conversely the lower the position of the car(4) is, the higher the counter weight(10) is. Thereby the efficiency of the constructed space is increased and the constructing cost is reduced.

Description

Roping Method of Elevator

The present invention relates to an elevator roping method for driving an elevator without a separate machine room by using a synchronous motor and disposing a sieve and a brake by miniaturizing a hoist in a hoistway.

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. However, the existence of the machine room is a burden in terms of building space utilization or design aspect, and the increase in construction cost is also a considerable amount.

In order to solve this problem in recent years, a disk-type hoist that has a synchronous motor and a sheave and a brake is introduced, and a method of driving the hoist by attaching the hoist between the upper guide rail and the wall of the hoistway without a separate machine room is required. do.

1 shows a typical example of a 2: 1 roping method for driving a car and a counter waiter when the hoisting device of an elevator is located in a separate machine room above the hoistway.

In FIG. 1, the car 4 and the counter weight 10 are located on the floor of the machine room 6 provided with the hoist 2 and the driven sheave 7 separately, and in the hoistway below the machine room, and the car 4 and the counter weight ( 10) Pulleys 3 and 9 are positioned at each upper portion, and the rope 5 is connected to the compensating pulley 11 positioned below the hoistway 8 at the lower portion of the car 4 and the counter weight 10, respectively.

The rope for driving the elevator has one end fixed to the ceiling of the machine room 6, which is hooked by a hoisting sheave 2 in the machine room 6 via a car pulley 3 on top of the car 4 and driven sheaves. It hangs on the counter weight pulley 9 in the upper part of the counter weight 10 over 7, and is fixed to the ceiling of a machine room again.

Therefore, the car 4 is moved up and down by friction between the hoisting sheave 2 and the rope as the motor in the hoisting machine rotates.

In the conventional rope roping method configured as described above, the presence of the machine room in which the hoisting machine is located brings many limitations such as waste of space in the building side and layout of the building in the design, and also increases the construction cost.

The present invention has been made in view of the above circumstances, and provides an elevator roping method for driving an elevator without a separate machine room by using a synchronous motor and disposing a sieve and a brake integrated in a hoistway. There is this.

Specific means of the present invention for achieving the above object,

In the roping method of the rope 5 for elevating the car 4 installed in the hoistway 8 from the guide rail 15,

Car side pulleys 13 are installed on both sides of the upper part of the car 4, and at the same time, the sheave 12 and the motor 17 are mounted on the guide rail 15, and one end of the rope is ceiling of the hoistway. It is fixed to the car side pulley 13, the sheave 12 and the counterweight pulley (9) characterized in that the other end is fixed to the ceiling of the hoistway.

1 is a typical illustration 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 above the hoistway.

2 and 3 are a perspective view and a plan view showing an example of the roping method when the hoist according to an embodiment of the present invention is fixed to the upper guide rail.

4 and 5 are exemplary views installed between the ceiling and the wall of the hoistway without fixing the hoist to the car side upper guide rail as another embodiment of the present invention.

<Explanation of symbols for the main parts of the drawings>

1: rope fixing part 4: car

5: rope 8: hoistway

9: counter weight pulley 10: counter weight

12: Sheave 13: Car side pulley

15: guide rail 17: motor

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

2 shows the roping structure when the hoist is fixed to the upper guide rail 15.

The rope 5 for driving the elevator in FIG. 2 has one end fixed to the hoist ceiling 1, which is secured to the upper guide rail 15 via a car pulley 13 at both ends of the car 4. It hangs on the counter weight pulley 9 located above the counter weight 10 via the sheave 12 and is fixed to the machine room ceiling 1 again.

Accordingly, the car 4 is driven in the vertical direction by friction between the hoisting sheave 12 and the rope 5 as the motor in the hoisting machine rotates.

The car pulleys 13 at both ends of the upper part of the car 4 are staggered with respect to the guide roller in order to balance while avoiding interference with the guide roller.

Accordingly, when the motor 17 is driven in one direction, the rope 5 is driven by the sheave 12, at which time the height of the rope fixing part 1 and the car 4 changes.

In this case, as the position of the car 4 increases, the counter weight 10 is relatively low. On the contrary, as the position of the car 4 decreases, the height of the counter weight 10 increases.

3 shows the plan view of FIG. 2 and shows the roping method in FIGS. 4 and 5 when the hoist is installed between the ceiling and the wall of the hoistway 8 without being fixed to the car side upper guide rail 15.

In the drawings, reference numeral 14 denotes a door, and 16 denotes a controller.

Thus, according to the present invention, by using the synchronous motor 17, the sieve 12, the brake is integrated into a miniature hoisting machine in the hoistway to drive the elevator without a separate machine room to increase the efficiency of the building space and reduce the construction cost You can do it.

As described above, according to the present invention, by using a synchronous motor, a sieve and a brake integrated with a miniature hoist in a hoistway to drive an elevator without a separate machine room, efficiency of the building space can be increased and construction cost can be reduced.
