Description

Balancing weight roping device and elevator roping device including same {ROPING DEVICE FOR BALANCE WEIGGHT AND ROPING DEVICE FOR ELEVATOR INCLUDING THE SAME}

The present invention relates to a counterweight roping device and an elevator roping device comprising the same.

In general, elevators used in buildings such as residential or business use are provided with a hoistway in a vertical direction in the interior of the building, whereby an elevator car and a balance weight travel up and down along the hoistway to move passengers or cargo.

As a result, occupying the necessary area of the elevator as much as the driving distance of the elevator car and counterweight, the problem of reducing the exclusive area of the building occurs, and the economic loss is increased exponentially with the increase of the building size and the construction cost. There was a problem that was a huge burden on the owner.

In order to solve this problem, the applicant's pre-registered patents of Korea Patent Registration 10-1817143 B1 and Korea Patent Registration 10-1917222 B1 to increase the diameter of the elevator rope winding drum and reduce the diameter of the counterweight rope winding drum, or By arranging a gear between an elevator rope winding drum and a counterweight rope winding drum, an invention for shortening the traveling distance of the counterweight has been proposed.

However, in this case, a problem arises in that the load of the counterweight is increased.

Specifically, when the load of the elevator car is applied to the outside of the large elevator rope winding drum and the load of the counterweight is applied to the outside of the small diameter rope rope winding drum, the shaft to which the elevator rope winding drum is connected is the counterweight rope. Since the take-up drum takes a larger torque than the connected shaft, a problem arises in that the load of the counterweight is increased to offset this torque difference.

Similarly, when the gear (the gear on the counterweight rope winding drum is larger in gear) is disposed between the elevator rope winding drum and the counterweight rope winding drum, the axis to which the elevator rope winding drum is connected in proportion to the gear ratio is the axis to which the counterweight rope winding drum is connected. Since greater torque is required, a problem arises in that the load of the counterweight must be increased to offset this torque difference.

A specific example for designing the first set distance S1 and the second set distance S2 is as follows.

Assuming that the weight of the car 22 of the elevator is 100 kg and the acceleration of gravity is 10 m / s ² and the diameter of the first counterweight rope winding drum 142 is 1 m, the first counterweight rope is determined by the load of the elevator car 22. The winding drum 142 takes a torque of 1000 N * m. Here, the torque applied to the first counterweight rope winding drum 142 is transmitted to the third intermediate gear 156 to be described later.

In addition, the torque applied to the first and second counterweight rope winding drums 132 and 134 is transmitted to the third intermediate gear 156, from which the first set distance S1 and the second set distance S2 are designed. Can be. Specifically, the weight of the balance weight 110 is 100kg, the diameter of the first, second, third intermediate gears (152, 154, 156) and the first, second rope winding drums (132, 134) is 0.5m, the first Assuming that the force applied to the counterweight from the counterweight rope winding drum 132 and the second counterweight rope winding drum 134 is vertical, the following equation may be established.

Equation (1): F1 = F2 + F0, F1 = F2 + 1000 N

Formula (2): F2 X S2 = F1 X S1

Equation (3): R1 X F1 + R2 X F2 = T1 + T2, 0.5m X F1 + 0.5m X F2 = 1000N * m,

Here, R1 and R2 are the diameters of the first counterweight rope winding drum 132 and the second counterweight rope winding drum 134, respectively, and T1 and T2 are the first counterweight rope winding drum 132 and the second rope winding drum, respectively. The torque applied to 134.

Here, the driving force for driving the elevator winding drum 142 'comes from the hoist 24', and the deceleration may be made by the reducer 26 '.

Although the counterweight roping device and the elevator roping device according to the embodiments of the present invention have been described as specific embodiments, these are only examples, and the present invention is not limited thereto, and the broadest range according to the basic idea disclosed in the present specification is provided. It should be interpreted as having. One skilled in the art can combine and substitute the disclosed embodiments to implement a pattern of a shape that is not indicated, but this is also within the scope of the present invention. In addition, those skilled in the art can easily change or modify the disclosed embodiments based on the present specification, it is obvious that such changes or modifications belong to the scope of the present invention.
