Description

Belt termination device {TERMINATION DEVICE OF BELT}

The present invention relates to a belt termination device, and more particularly to a belt termination device for connecting and fixing the ends of a drive belt for an elevator.

In general, an elevator system is provided with a car serving as a vehicle, a counterweight to compensate the weight of the car and passengers, a driving rope connecting the vehicle and the counterweight, and a traction sheave on which the driving rope is wound, and rotating the traction sheave to create traction for the car. It includes a hoisting machine.

As a conventional driving rope, a driving rope formed of twisted or twisted steel wire is used, and the conventional driving rope has a wide cross-sectional area to have sufficient strength, and for this purpose, a diameter is formed thick, which reduces the flexibility of the driving rope. Results.

In addition, in order to wind the driving rope with reduced flexibility, a traction sheave having a large diameter is required, and a problem arises in that the efficiency of the traction machine decreases as the diameter of the traction sheave increases.

In order to solve such a problem, in recent years, as shown in FIG. 1, a planar drive consisting of a core (c) arranged to form a transverse row and a buffer member (s) coating the arranged cores has replaced the driving rope. Belt (b) is used, and such a drive belt (b) has an advantage that even if the cross-sectional area is formed to have sufficient strength, it can have relatively excellent flexibility and thus can be wound even on a sheave having a small diameter.

On the other hand, as an end fixing means for connecting and fixing the ends of the drive belt (b) described above, a wedge on which the drive belt (b) is wound and a socket to accommodate the wedge are provided on the circumferential surface, and the drive belt (b) on the wedge When received in the socket in a wound state, a wedge-type end fixing device is used that allows the drive belt b interposed between the inner surface of the socket and the circumferential surface of the wedge to be fixed by pressure and frictional force.

However, in the conventional wedge-type end fixing device, slip movement of the driving belt (b) occurs in the end fixing device due to insufficient fixing force, and when the slip movement occurs, the buffer member (s) is due to the difference in elongation from the core (c). Separated from the core (c). This causes physical damage to the buffer member (s), and a problem arises in that the physical damage to the buffer member (s) may lead to physical damage to the core (c).

8 is a diagram illustrating a slip preventing means 300 formed by an angle formed by the first and second outer peripheral surfaces according to the first embodiment of the present invention.

As the wedge 200 moves closer to the belt through-hole 130 in the socket 100, the slip preventing means 300 is formed with the first and second inner surfaces 150 and 170 of the socket and the first of the wedge. And the second outer peripheral surfaces 210 and 230 may be in close contact with each other to intensively strengthen the contact pressing force on the driving belt B in some areas.

Specifically, as shown in FIG. 8, at least one of the first and second inner surfaces 150 and 170 of the socket is disposed to obliquely cross each other while forming an inclined surface, and the first and second outer circumferential surfaces 210 of the wedge , 230 may be disposed in a direction obliquely crossing each other so as to correspond to the first and second inner surfaces 150 and 170 of the socket.

At this time, it is provided so that the angle θ2 formed by the first and second outer circumferential surfaces 210 and 230 is greater than the angle θ1 formed by the first and second inner circumferential surfaces 150 and 170, and in some areas P1 The distance L1 from the first and second outer circumferential surfaces 210 and 230 to the first and second inner circumferential surfaces 150 and 170 is in the first and second outer circumferential surfaces ( It is formed to be shorter than the distance (L2) from the first and second inner surfaces (150, 170) from 210 and 230, so that the close pressing force to the driving belt (b) is concentrated and strengthened in some areas (P1). I can.

At this time, if the difference between the above-described angles is too large, the pressure does not occur in a region other than the region where the close pressing force is concentrated, and a problem occurs, and if it is formed too finely, the region P1 where the close pressing force is concentrated is not formed. The angle formed by the second outer circumferential surfaces 210 and 250 may be formed to be approximately 1.1 times larger than the angle formed by the first and second inner surfaces 150 and 170.

9 is a diagram illustrating a pressure concentrator according to a first embodiment of the present invention. And FIG. 10 is a diagram illustrating the pressure formed by the pressure concentrator according to the first embodiment of the present invention.

9 to 10, the slip prevention means 300 according to the present embodiment is driven while the driving belt (b) is wound around the circumferential surface so that the frictional force between the driving belt (b) and the wedge 200 increases. It may include a pressure concentration portion 330 formed in a partial region of the circumferential surface of the wedge 200 so as to locally concentrate the pressing force on the belt (b).

In addition, the pressure concentrating part 330 may be formed in a region furthest from the belt through hole 130 among the circumferential surfaces of the wedge 200 and may be formed to protrude further outward than the adjacent region. Here, the pressure concentration unit 330 may form a continuous surface, or may form a discontinuous surface to form a corner.

Specifically, although the drive belt (b) has relatively improved flexibility compared to the conventional drive rope, there is a limitation in flexibility due to the core (c) provided therein. Therefore, there is a limit to the amount of bending of the drive belt b, and as shown in FIG. 9A, the curvature in the region a1 farthest from the belt through hole 130 among the circumferential surfaces of the wedge 200 is the drive belt ( If it is smaller than the curvature caused by the bending of b), it may not come into close contact with the drive belt b in this region a1, thereby causing slip of the drive belt b.

In order to prevent this, as shown in FIG. 9B, in this embodiment, a partial region a2 of the central portion of the third outer circumferential surface 250 is formed with a curvature greater than the curvature formed by bending of the driving belt b. The pressure concentrating part 330 is formed so that the close pressing force of the driving belt b is concentrated, thereby reducing the occurrence of separation.

In addition, as shown in FIG. 10, when the pressure concentration portion 330 is formed in the area P2 where the close pressing force of the third outer circumferential surface 250 is concentrated, the third outer circumferential surface 250 is pulled downward by a force that pulls the driving belt b downward. At least one pressure is concentrated in the areas (P1, P3) that are bent from the third outer circumferential surface 250 to the first or second outer circumferential surface with the pressure concentration unit 330 formed on the outer circumferential surface 250 as an axis. The portion 330 is additionally formed, whereby the fixing force may be further improved.
