Rope installation structure of elevator {STRUCTURE FOR A ROPE ESTABLISHMENT OF AN ELEVATOR}

The present invention relates to a rope installation structure of an elevator, and more particularly, in the rope installation structure for elevating an elevator car in a hoistway, by 1: 1 roping, the elevator can increase efficiency while simplifying the rope structure. The rope installation structure of the present invention.

In general, an elevator is a device for elevating passengers or cargo along a hoistway formed along the up and down direction of a building. A so-called rope type elevator equipped with a hoisting machine for elevating and driving a car and a counterweight by frictionally contacting with the wire rope on the upper side and rotating it is widely used.

However, in such a rope type elevator, a separate installation space called a machine room is provided on the upper side of the hoistway so as to install a hoist and a control panel, which increases the occupied space of the elevator and impairs the service capacity per unit space. There is this.

Recently, a so-called machine roomless elevator, which excludes a machine room to improve service capacity per unit space occupied by an elevator, is disclosed in Korean Patent Publication No. 1996-000750 and US Patent No. US 5,566,785.

In an elevator without such a machine room, it is a main concern to reduce the volume of the hoisting machine without degrading the function of the hoisting machine and to move the hoisting machine to an appropriate space in the hoistway.

1 is a view schematically showing an elevator without a conventional machine room, in which the elevator 10 includes a car 1 arranged to be able to move up and down in a hoistway, and a balance weight arranged to be able to move up and down on one side of the car 1. (2), the hoist (3) provided in the upper region of the hoistway corresponding to the car (1) and the counterweight (2), and the car (1) and the counterweight are arranged so as to be in friction contact with the hoist (3) It consists of the rope 4 which raises and lowers (2).

At this time, the bottom region of the car 1 is provided with the first and second pulleys 5a and 5b spaced apart in parallel to each other, and the upper region of the counterweight 2 is integrated with the counterweight 2. The counterweight pulley 6 is provided so that it may be possible. The rope 4 has one end fixed to the upper region of the upper hoistway of the first pulley 5a, the other end thereof being extended downward, and upwardly extended again via friction contact with the first and second pulleys 5a and 5b. After the friction contact with the hoist (3) is extended downward through the balance weight pulley (6) is fixed to the upper area of the hoistway.

By the way, in the conventional elevator 10, the rope installation structure is generally 2: 1 roping, so that the length of the rope is increased, and thus the capacity of the motor required to increase the torque required for moving the car is increased. There was a problem that the installation cost is enormous.

The present invention has been made to solve the above problems, the object of the present invention is to increase the efficiency while simplifying the rope structure by 1: 1 rope in the installation structure of the rope for elevating the elevator car in the hoistway. To provide an elevator rope installation structure that can be.
