Description

Apparatus for equalizing tensions of main ropes of an elevator}

First of all, the terms used in the present specification,

“Rope fastening member” consists of, or consists of, rope sockets, thimble rods, buffer springs, spring seats, turnbuckles, hitch plates, nuts, and split pins that are commonly used in rope fastening. Means parts.

"Beam" means the beam of a cana counterweight, including the beam of the hoistway or machine room to which the rope is fastened.

The present invention relates to an apparatus for automatically equalizing an uneven tension between rope mutually in an elevator suspended by a plurality of ropes.

In elevators or similar arrangements in which a plurality of ropes support a single load, when there are relative length differences between the ropes, the loads on each of them are not equal and tension imbalance occurs. Rope length differences generally arise from the fact that wire rope characteristics are difficult to match the relative lengths between the ropes during initial installation or replacement due to the bending and rigidity of the ropes. It is also caused by the relative length change between ropes over time due to differences in expansion ratio, material failure of sheaves or ropes, and positional deviations of the car. This allows ropes that are relatively shorter than other ropes to be subjected to excessive tension, which causes wires to wear rapidly, to deform or break, and to cause premature wear of the grooves through which the rope passes. Frequent replacement of the wheels and the unbalance of the loads between the ropes causes vibrations in the longitudinal and transverse directions during driving, thereby making the passengers nervous. This is similar to the improper wheel alignment in automobiles, which rapidly shortens the life of tires and related parts, and reduces steering ability and ride comfort.

In order to prevent this problem, the current tension adjustment is manually performed at the site where the elevator is installed, but it has the following problems.

A) The upper part of the machine room or the car where the place to detect or adjust the tension imbalance is isolated from most people's passages, and the entrance and exit for the steady check is cumbersome.

B) As described above, the tension imbalance starts from the installation work or the replacement of related parts and is the biggest cause, so even if the imbalance is confirmed, accurate adjustment is difficult.

C) Even if correct adjustments are made, subsequent imbalances will continue until reconfirmation,

D) The identification of imbalances is inconsistent with a profound imbalance.

E) Imbalances play a role of balancing at the same time (relatively shorter ropes to increase their length and to promote abrasion of the sieve groove through which the ropes pass). .

Therefore, in order to solve such a problem, a technical means for automatically adjusting the tension is required in real time, and as a technical means for making the tension adjustment in real time automatically, several technologies different from the present invention are different from the present inventors. Although it has been disclosed by the investees, most of the disclosed technical means have some problems in terms of production, use, and function, and commercialization is not realized.

Accordingly, the present invention aims to simplify the components in order to provide an effective technical means in manufacturing and use as well as in the functional aspect of equalizing the tension imbalance of the rope.

According to the present invention, a moving car 32 is disposed on each rope through a rod and a rope fastening member on one side of a rope end on a car, a balance weight, a machine room or a hoistway to which the rope is fastened, and the moving car is applied to the tension of the rope supported by the driving car. It is characterized in that the balance rope and the smooth car is provided so as to move along.

Referring to the preferred embodiment of the configuration of the present invention in detail referring to the drawings as follows.

In general, the elevator rope is fastened directly to the beam, and the present invention, as shown in Figure 1, the ropes 32 through the rope fastening member 3 and the rod 20 is disposed on each of the ropes 2 as a result the ropes eventually Is supported by a moving car, and a moving car 31 and a balancing rope 40 are provided so that the moving car moves according to the tension (load) of the supporting ropes. The frame for fixing is configured such that a case 10 having a rod hole for protruding the rod 20 can be fastened to the beam 4 at an upper portion thereof.

The pulley may be arranged in the transverse direction as shown in FIG. 1, or in the longitudinal direction as shown in FIG. 4, and may be arranged in a staggered manner between the pulley and the pulley as shown in FIG. 5. This can be easily adapted to a straight line, zigzag, circle, etc. according to the rope arrangement of the actual elevator apparatus.

The balance rope 40 may or may not be formed with an end according to the arrangement of the pulley, and when the end is formed, it is fixed by the balance rope fixing piece 41 as shown in FIG. 4.

2 is a view showing an embodiment different from the above embodiment, among the components of the embodiment, a pulley 31, a moving 32, a fixed gear pulley 31a instead of the balance rope 40, a moving gear pulley (32a), characterized in that the balance chain 40a is configured, the drawings are omitted, but in this embodiment it will be possible to arrange the arrangement of the gears in the longitudinal direction between the gears, or to arrange the fixed gear and the shifting gear in a staggered manner.

3 illustrates the result of an operation in which the above-described configuration equalizes the tension between the ropes 2 having a relative length difference, and the operation process is briefly described with reference to the balance rope 40. While stopping at the point where the force balances while pulling in the opposite direction to (2), the balance rope 40 is located in the flow space of all sections, so that the load itself is equally loaded at any point. Absorption of tension caused by relative length change is absorbed in real time.

The present invention is simple in its construction as described above, and is easy to manufacture, and there is almost no resistance that hinders the movement of the balance rope, so that the function of equalizing the tension of the rope is excellent. This prevents vibrations transmitted by the ropes and reduces labor associated with maintenance.
