Description

TECHNICAL FIELD [0001] The present invention relates to an elevator rope and an elevator device using the elevator rope.

The present invention relates to an elevator rope in which a plurality of strands are twisted to each other, and an elevator apparatus using the same.

In a conventional wire rope for a load / unload machine, a plurality of side strands are twisted around the outer periphery of the rope core portion. Each side strand is formed by twisting a plurality of steel wires. In some of the side strands, a part of the strands of the outermost layer is plated (see, for example, Patent Document 1).

In other conventional wire ropes for cargo handling machines, the inner circumferential layer of the side strands is constituted by a plurality of plated wire rods. The outer layer of the side strands is constituted by a plurality of non-plated layers (see, for example, Patent Document 2).

On the other hand, in a conventional elevator rope, a data plate (name plate) on which manufacturing information such as a manufacturing time and a production lot is recorded is attached to the rope itself at the time of shipment of the rope. After shipment of the rope, the data plate is detached from the rope and attached to the equipment of the elevator in which the rope is used. If it is necessary to confirm the manufacturing information for some reason during use of the rope, the data plate is confirmed by the operator.

Patent Document 1: Japanese Patent No. 2920082 Patent Document 2: JP-A-8-176976

However, in the conventional elevator rope, for example, when adjacent elevators are elevators having the same specifications, the combination of the data plate and the rope may become unclear. When the rope is exchanged for any reason, the situation is that the used rope and the data plate do not adequately correspond to each other, for example, because the data plate of the rope before exchange is not exchanged with the data plate of the new rope May occur. In addition, once such a disruption has occurred, it becomes difficult to confirm the correspondence between the rope and the data plate thereafter.

On the other hand, in the conventional wire rope disclosed in Patent Documents 1 and 2, since only a part of the wire is plated, manufacturing information can not be displayed on the wire rope. Further, in Patent Document 1, it is easy to distinguish from other strands by plating the identification steel wire (steel wire) for confirming the aging of the rope, and there is no mention of the display of the manufacturing information It is not.

An object of the present invention is to provide an elevator rope that can confirm the corresponding manufacturing information more reliably, and an elevator apparatus using the elevator rope.

The elevator rope according to the present invention has a plurality of outer layer strands arranged on the outer circumference and each outer layer strand has a plurality of outer layer strands arranged on the outer circumference, The outer layer strand includes a plurality of information display strands that display manufacturing information of the elevator rope, and the outer layer strand of the information display strand includes a plurality of first stranded wires, a plurality of second stranded wires having different colors from the first stranded wire, And the manufacturing information is displayed by a combination of the arrangement states of the second element wires in the two or more information display strands.

Embodiment 1

1 is a side view showing an elevator apparatus according to Embodiment 1 of the present invention. In the drawing, a machine room 2 is provided at an upper portion of a hoistway 1. In the machine room 2, a machine table 3 is provided. On the machine table 3, a traction machine 4 is supported. The traction machine 4 has a drive sheave 5 and a traction machine main body 6. The traction machine main body 6 has a traction machine motor for rotating the drive sheave 5 and a traction machine brake for braking the rotation of the drive sheave 5. [

On the machine table 3, a deflector sheave 7 is mounted. A plurality of elevator ropes 8 (only one is shown in the drawing) are wound around the driving sheave 5 and the deflector sheave 7. A plurality of rope grooves (not shown) in which the elevator rope 8 is inserted are formed on the outer periphery of the drive sheave 5.

An elevator car (9) is connected to the first end of the elevator rope (8). A balance weight 10 is connected to the second end of the elevator rope 8. The elevator car 9 and the balance weight 10 are suspended by an elevator rope 8 and ascend and descend in the hoistway 1 by the driving force of the hoist 4.

A pair of elevator car guide rails 11 for guiding the elevator car 9 to ascend and descend and a pair of counterweight guide rails 12 for guiding the elevation of the balance weight 10 are installed in the hoistway 1 have.

The elevator car 9 has an elevator car frame 13 to which an elevator rope 8 is connected and an elevator car room 14 which is supported by the elevator car frame 13.

Fig. 2 is an enlarged side view showing a part of the elevator rope 8 in Fig. 1, and Fig. 3 is a sectional view along the line III-III in Fig. The elevator rope 8 has a core rope 21 and a plurality of (eight in this example) outer strand 22 arranged on the outer periphery of the core rope 21. The core ropes 21 are formed by twisting fibers. The outer layer strands 22 are directly twisted around the outer periphery of the core rope 21 to form the outermost layer of the elevator rope 8.

Each of the outer layer strands 22 includes a core strand 23 disposed at the center, a plurality of (nine in this example) inner strand strands 24 twisted around the core strands 23, And has a plurality of (nine in this example) outer layer strand 25 arranged therein. The outer layer strand 25 is twisted around the outer strands of the inner layer strand 24.

As the core strand 23, the inner strand strand 24 and the outer strand strand 25, all the stranded wire is used. The diameter of the inner layer strand 24 is smaller than the diameter of the core strand 23 and the diameter of the outer layer strand 25. The number of the inner layer strands 24 is the same as the number of the outer layer strands 25. As described above, the elevator rope 8 of the first embodiment has the construction of 8 x S (19).

The outer layer strand 22 includes a plurality of (six in this example) information display strands, that is, first to sixth information display strands 22a to 22f, which display manufacturing information of the elevator rope 8, A division position display strand 22g for indicating the division position (leading position) of the manufacturing information, and a direction display strand 22h for indicating the reading direction of the manufacturing information.

The outer layer strand 25 in each of the information display strands 22a to 22f has a plurality of (seven in this example) first strands 25a and a plurality of strands different in color from the first strands 25a 2) second small wires 25b. In Fig. 2, the first element wire 25a is shown in white and the second element wire 25b is given a plurality of dots. In Fig. 3, the first elemental line 25a is given a normal hatching and the second elemental line 25b is painted in black.

The first element wire 25a of Embodiment 1 is a bare wire to which no coloring is applied. The second element wire 25b of the first embodiment is a colored wire subjected to color processing. In addition, the coloring process of Embodiment 1 is a zinc plating process. That is, the second element wire 25b is a plating wire.

In the elevator rope 8, manufacturing information is displayed by a combination of the arrangement states of the second element wires 25b in the two or more information display strands 22a to 22f. In the example of Fig. 3, the arrangement pitch of the second element wires 25b in the circumferential direction in the cross section perpendicular to the longitudinal direction of the information display strands 22a to 22f is used as the arrangement state of the second element wires 25b have.

The partition indication strand 22g is different in appearance from all the information display strands 22a to 22f by changing the disposition state of the first and second element wires 25 and 25b. In this example, the outer layer strands 25 of the division position indicating strand 22g are all the same color. Specifically, in the division position indicating strand 22g, all the outer layer strands 25 are spirals.

The direction indicating strand 22h is disposed adjacent to the division position indicating strand 22g. The directional display strands 22h can be used to display all the information display strands 22a to 22f and the divisional position display strands 22g and the outline shape (outer appearance) by changing the arrangement state of the first and second small wires 25 and 25b. ) Is different. Specifically, the outer layer strand 25 of the direction indicating strand 22h is composed of one second strand 25b and eight first strands 25a.

In this example, the position of the division position indicating strand 22g is set as the division position of the manufacturing information, and the manufacturing information is set to be read in the direction in which the direction indicating strand 22h is adjacent to the division position indicating strand 22g have. For this reason, in the manufacturing information, the information display strand 22a is at the head and the information display strand 22f is at the end. In this example, the first and second information display strands 22a and 22b are manufactured by the year, the third and fourth information display strands 22c and 22d by the manufacturing month, and the fifth and sixth information display strands 22e, and 22f, respectively.

Fig. 4 is an explanatory view showing a first example of a display method of manufacturing information by the information display strands 22a to 22f of Fig. 3; Fig. In this example, one piece of information is displayed with one set of two information display strands. In Fig. 4, the information display strand on the upstream side in the reading direction is referred to as the " first " and the information display strand on the downstream side is referred to as the " second "

For example, the first and second information display strands 22a and 22b in FIG. 3 indicate " 2 " in FIG. Thus, the worker can know the year of manufacture corresponding to " 2 " from, for example, a corresponding table (not shown) or a predetermined calculation method.

The third and fourth information display strands 22c and 22d in Fig. 3 indicate " 10 " in Fig. As a result, the operator can know that the month of manufacture is October. Alternatively, the production month corresponding to " 10 " can be known from, for example, a corresponding table (not shown) or a predetermined calculation method.

In addition, the fifth and sixth information display strands 22e and 22f in Fig. 3 show " 16 " in Fig. As a result, the operator can know that the production lot is " 16 " (rope produced at the 16th of the month). Alternatively, the production lot corresponding to " 16 " can be known from, for example, a correspondence table (not shown) or a predetermined calculation method.

Normally, the elevator rope is released from a long rope manufactured at one time by a length corresponding to the elevator device to which it is applied.

Fig. 5 is an explanatory view showing a second example of the display method of the manufacturing information by the information display strands 22a to 22f of Fig. 3. In the example of Fig. 4, the arrangement pitch of the second element wires 25b is used as the arrangement of the second element wires 25b. On the other hand, in the example of Fig. 5, the number of the second elemental wires 25b is used as the arrangement of the second elemental wires 25b. That is, the manufacturing information is displayed by the combination of the number of the second small wire 25b in the first information display strand and the number of the second small wire 25b in the second information display strand.

Fig. 6 is an explanatory diagram showing a third example of a display method of manufacturing information by the information display strands 22a to 22f of Fig. 3; In the example of Fig. 6, both the arrangement pitch and the number of the second element wires 25b are used as the arrangement of the second element wires 25b. This makes it possible to increase the number of combinations of the arrangement state of the second element wire 25b in the first information display strand and the arrangement state of the second element wire 25b in the second information display strand.

In the elevator rope 8, since the manufacturing information is displayed by the combination of the disposition states of the second element wires 25b in the information display strands 22a to 22f, the manufacturing information can be displayed on the rope itself , It is possible to confirm the corresponding manufacturing information more reliably. This makes it possible to more accurately combine the history of the elevator ropes 8 actually used at the time of manufacturing.

Since at least one of the arrangement pitch and the number of the second element wires 25b is used as the arrangement state of the second element wire 25b, the arrangement state of the second element wire 25b can be easily Can be changed.

In addition, since the division location indicating strand 22g is used, the division location of the manufacturing information can be easily grasped.

Furthermore, since the outer layer strands 25 of the division position indicating strand 22g are all made the same color, the division position of the manufacturing information can be grasped more quickly.

Further, since the direction indicating strand 22h is used, the reading direction of the manufacturing information can be grasped easily.

In addition, since the first element wire 25a is a spiral and the second element wire 25b is a coloring wire, manufacturing information can be easily displayed only by coloring a part of the outer layer element wire 25 .

In addition, since the plating process is used as the coloring process, the use of the elevator rope 8 makes it possible to suppress the coloration from becoming thinner, and the manufacturing information can be displayed stably over a long period of time.

The manufacturing information is not limited to the production year, the production month, and the production lot, but may include, for example, a manufacturer, a production date, a test result, and the like.

The plating process is not limited to zinc plating, but may be, for example, nickel plating, chrome plating, aluminum zinc alloy plating, copper plating, or the like.

In addition, the coloring processing is not limited to the plating processing, and for example, the coating processing may be applied.

Further, in the above example, the first wire element is used as the spiral wire and the second wire element is used as the color wire, but the opposite may be used.

In the above example, the manufacturing information is displayed by only two kinds of the first and second small wires 25a and 25b, but a combination of three or more colors (three or more colors) may be used.

In addition, in the above example, one piece of information is displayed by making one set of two pieces of information display strands, but one piece of information may be displayed with one set of three or more pieces of information display strands. For example, Fig. 7 shows an example in which one piece of information is displayed with one set of three information display strands.

In addition, the division position indicating strand is not limited to the above example, and for example, the outer layer strands, in which all the outer layer strands are coloring lines, may be partition display strands, or the outer layer strands including a specific number of coloring strands, It is okay to use display string.

Also, the direction display strand is not limited to the above example, and for example, an outer layer strand including a specific number of coloring lines other than one may be used as the direction display strand.

In addition, the segment display strand 22g and the direction display strand 22h may be reversed. That is, the outer layer strands 22 having the same color as the outer layer strands 25 may be used as the orientation display strands, and the outer layer strands 22 having the specific number of outer layer strands 25 colored as the partition line display strands.

Furthermore, if the division position can be known from the characteristic of the information display strand, the division position display strand may be omitted.

If the reading direction is predetermined, the direction indicating strand may be omitted.

For example, the information display strand may also be used as the partition display strand or the direction display strand by coloring at least one colored line of the information display strand with a color different from that of the other information display strands.

Further, in the above example, all of the information display strands include two or more second strands, but if the segment position display strand and the direction display strand are not used, or the distinction from the segment position display strand and the direction display strand The information-indicating strand including only one second strand or the information-indicating strand not including the second strand may be included in the outer strand strand.

In addition, it is not absolutely necessary to divide all the outer layer strands into any one of the information display strand, the partition position display strand, and the direction display strand. For example, in the case where the number of outer layer strands is large, an outer layer strand which does not display the manufacturing information and the direction of reading the partition position may be included.

In the above example, the elevator rope 8 of 8xS (19) in which the core rope 21 of fibrous material is disposed at the center is shown, but the present invention can also be applied to wire ropes of other configurations. For example, the present invention can be applied to a rope having a three-layer structure in which a layer of an inner layer strand is disposed between a core rope and an outer layer strand, or a rope in which a core rope is constituted by a rope.

In addition, the type of elevator apparatus to which the elevator rope of the present invention is applied is not limited to the type shown in Fig. For example, the present invention can be applied to an elevator without a machine room, an elevator device with a 2: 1 roping system, an elevator device with a multi-car system, or a double deck elevator.

Further, the elevator rope of the present invention can be applied to a rope other than a rope for suspending the elevator car 9, for example, a compensation rope or a governor rope.
