The Y direction is along the lateral direction (thickness direction) of the main rope transport device 10 and along the width direction of the hoistway 3. The Z direction is along the height direction of the main rope transport device 10 and along the height direction (vertical direction) of the hoistway 3.

As shown in FIG. 1, the elevator 1 is configured as a so-called slip-type elevator in which, for example, a car 4 in a hoistway 3 and a counterweight 5 as a counterweight are connected by a main rope 9. ..

One end of the main rope 9 is fixed to, for example, the upper end of the hoistway 3 or the rope stopper 25 provided in the machine room 2 while being wound around the sheave 23 provided in the car 4. ..

The other end of the main rope 9 is fixed to the upper end of the hoistway 3 or the rope stopper 26 provided in the machine room 2 while being wound around the sheave 24 provided in the counterweight 5, for example. There is.

Further, the intermediate portion of the main rope 9 is wound around the hoisting sheave 7 and the hoisting sheave 8 of the hoisting machine 6 provided in the machine room 2. The machine room 2 is provided with a control panel (not shown), a motor for driving the hoisting machine 6, and the like.

In the elevator 1, the hoisting machine 6 is driven under the control of the control panel, so that the car is placed between one end (rope stopper 25) and the other end (rope stopper 26) of the main rope 9. 4 and the counterweight 5 move up and down in the Z direction and the opposite direction to each other.

As a result, the car 4 can be moved to the landing 21 on any destination floor. Note that FIG. 1 shows only one of the plurality of landings 21 for convenience. The landing 21 is located in the X direction of the hoistway 3, and the machine room 2 is located in the Z direction of the hoistway 3, that is, above.

FIG. 2 is an enlarged view of the main rope transfer device 10 of FIG. As shown in FIG. 2, the main rope transfer device 10 includes, for example, a frame body 11, a rope guide 12, a resistance mechanism 13, and a braking mechanism 14.

The main rope transfer device 10 is installed, for example, on the machine bed 19 of the machine room 2. The main rope transfer device 10 is configured in a substantially U shape that is open toward the hoisting machine 6 (downward) in the line of sight in the Y direction. In other words, the main rope transfer device 10 is provided so as to surround the hoisting machine 6.

In the present embodiment, such a configuration is configured so that the transport path 20 of the main rope 9 by the main rope transport device 10 is secured directly above the hoisting machine 6.

As a result, the workability of the work of changing the hoisting machine 6 to the transport path 20 and the work of returning from the transport path 20 to the hoisting machine 6 at the time of exchanging the main rope 9 is improved. The main rope transfer device 10 is also referred to as a main rope replacement assisting device or the like.

FIG. 3 is a diagram showing a state in which the resistance mechanism 13 and the braking mechanism 14 of the main rope transfer device 10 of FIG. 2 are removed. As shown in FIG. 3, the frame body 11 has, for example, a pair of columns 11a and beams 11b.

The pair of columns 11a are provided in parallel with each other at intervals in the X direction. The distance between the columns 11a in the X direction is substantially the same as the width of the folded portion 9a (curved portion) of the main rope 9 wound around the hoisting sheave 7 and the deflecting sheave 8 (see FIG. 2) in the X direction. ..

The beam 11b extends between the upper ends of the pair of columns 11a. The beam 11b is located above the hoisting sheave 7 of the hoisting machine 6. The beam 11b is also referred to as a lateral member or the like, and the support column 11a is also referred to as a vertical member or the like.

The rope guide 12 is provided, for example, corresponding to the two corner portions 11c between the support column 11a and the beam 11b of the frame body 11. The rope guide 12 has a guide rail 12a and a mounting piece 12b, respectively.

The guide rail 12a is, for example, configured in an arc shape centered on the central portion of the frame body 11. In other words, the guide rail 12a is curved in a convex state from the corner portion 11c to the side opposite to the central portion of the frame body 11.

As shown in FIG. 2, the guide rail 12a smoothly connects, for example, the resistance mechanism 13 provided on the frame body 11 and the braking mechanism 14. Then, in the present embodiment, the guide rail 12a, the resistance mechanism 13, and the braking mechanism 14 constitute a series of transport paths 20.

Further, the guide rail 12a is formed in a tubular shape having a substantially U-shaped cross section that is opened in the Y direction, that is, in the front direction of the paper surface of FIG. 2, for example. The main rope 9 can be replaced with the guide rail 12a by being inserted from the open portion of the guide rail 12a.

The guide rail 12a is not limited to this example, and may have, for example, a substantially U-shaped cross section that is opened upward. The guide rail 12a movably supports the main rope 9 along the transport path 20.

Further, the guide rail 12a is made of a flexible material such as synthetic resin or rubber. That is, the guide rail 12a can be deformed along the main rope 9. The guide rail 12a is also referred to as a flexible tube or the like.

The mounting piece 12b is formed, for example, in the shape of a quadrangular plate extending along the beam 11b. The rope guide 12 is provided with a plurality of mounting pieces 12b at intervals in the longitudinal direction of the guide rail 12a. The rope guide 12 is detachably connected to the beam 11b by a connector such as a screw or a bolt that penetrates the mounting piece 12b in the Y direction.

As shown in FIG. 2, the resistance mechanism 13 is located, for example, between two rope guides 12. In other words, the resistance mechanism 13 is interposed in the middle position of the transport path 20. In the present embodiment, the beam 11b is provided with three resistance mechanisms 13 arranged side by side in the X direction. The number of resistance mechanisms 13 is not limited to this example, and may be, for example, one, two, or four or more.

For example, the main rope 9 is attached to the resistance mechanism 13 in a state of being sandwiched from the Z direction and the opposite direction. Then, in the present embodiment, the acceleration due to the own weight of the main rope 9 is suppressed by a constant sliding resistance between the resistance mechanism 13 and the main rope 9. The resistance mechanism 13 is also referred to as a speed-reducing mechanism, a speed-reducing brake, or the like.

FIG. 4 is a front view of the resistance mechanism 13. As shown in FIG. 4, the resistance mechanism 13 includes, for example, a shaft 13a, a spring 13b, a spring receiver 13c, a nut 13d, a movable portion 13e, a fixing portion 13f, and a mounting rib 13g. ing.

The resistance mechanism 13 is provided with, for example, two mounting ribs 13g at intervals in the X direction. The resistance mechanism 13 is detachably connected to the beam 11b of the frame 11 by a connector such as a screw or a bolt that penetrates the mounting rib 13g in the Y direction.

A spring 13b, a spring receiver 13c, a nut 12d, a movable portion 13e, and a fixing portion 13f are attached to the shaft 13a in a state of penetrating in the Z direction. The shaft 13a is also referred to as a support rod or the like.

The fixing portion 13f has, for example, a fixing plate 13f1 and a sliding member 13f2 as a fixing shoe. The lower surface of the fixing plate 13f1 is supported by the lower end of the shaft 13a, and the sliding member 13f2 is attached to the upper surface of the fixing plate 13f1. The fixing plate 13f1 is connected to, for example, the mounting rib 13g.

The sliding member 13f2 is formed, for example, in the shape of a quadrangular plate extending along the fixing plate 13f1. The upper surface of the sliding member 13f2 faces the main rope 9 (see FIG. 6) and is slidable with the main rope 9. The sliding member 13f2 is also referred to as a braking member, a friction member, or the like.

The movable portion 13e has, for example, a movable plate 13e1 and a sliding member 13e2 as a movable shoe. The upper surface of the movable plate 13e1 is connected to the spring 13b, and the sliding member 13e2 is attached to the lower surface of the movable plate 13e1.

The sliding member 13e2 is formed, for example, in the shape of a quadrangular plate extending along the movable plate 13e1. The lower surface of the sliding member 13e2 faces the main rope 9 and is slidable with the main rope 9. The sliding member 13e2 is also referred to as a braking member, a friction member, or the like.

In the present embodiment, for example, the sliding member 13e2 and the sliding member 13f2 are made of hard wood that is more flexible than the main rope 9. As a result, the load on the main rope 9 at the time of deceleration is reduced.

The spring 13b is, for example, a compression spring that can be elastically compressed in the Z direction, and is interposed between the spring receiver 13c and the movable portion 13e. In the present embodiment, for example, when the spring 13b has a free length, the gap 13s in the Z direction between the movable portion 13e and the fixed portion 13f is set to be smaller than the diameter of the main rope 9.

As a result, when the main rope 9 is set in the gap 13s, the movable portion 13e is urged toward the fixed portion 13f, and by extension, the desired frictional resistance between the sliding members 13e2, 13f2 and the main rope 9 is achieved. (Friction) is secured.

The gap 13s is open in the Y direction. The main rope 9 can be replaced with the resistance mechanism 13 by being inserted from the open portion of the gap 13s when the main rope 9 is replaced.

The nut 13d is located on the opposite side of the spring receiver 13c from the spring 13b, that is, above. The inner peripheral surface of the nut 13d is provided with a female screw portion that meshes with a male screw portion provided on the outer peripheral surface of the shaft 13a.

In the present embodiment, for example, by tightening the nut 13d, the spring receiver 13c, the spring 13b, and the movable portion 13e are configured to be movable downward with respect to the shaft 13a. As a result, for example, even when the sliding members 13e2 and 13f2 are worn due to aged use, a certain speed-reducing effect can be obtained.

FIG. 5 is a front view of the braking mechanism 14. As shown in FIG. 5, the braking mechanism 14 has, for example, a base 14a, a lever 14b, a movable portion 14c, a fixing portion 14d, and a braking force adjusting screw 14e.

The movable portion 14c has, for example, a sliding member 14c1 as a movable shoe, and the fixed portion 14d has, for example, a sliding member 14d1 as a fixed shoe. The sliding members 14c1 and 14d1 are formed in a rectangular plate shape intersecting the X direction.

A main rope 9 (see FIG. 6) is arranged between the two sliding members 14c1 and 14d1. That is, the sliding members 14c1 and 14d1 face the main rope 9 and can slide with the main rope 9. The sliding members 14c1 and 14d1 are also referred to as braking members, friction members and the like.

Further, the movable portion 14c is connected to the lever 14b. The movable portion 14c is configured to be movable along the X direction between the non-braking position P1 and the braking position P2 in conjunction with the rotation of the lever 14b with respect to the base 14a around the center of rotation.

In the present embodiment, for example, when the movable portion 14c is positioned at the non-braking position P1, no surface pressure is generated between the sliding members 14c1, 14d1 and the main rope 9, and the movable portion 14c is at the braking position P2. A surface pressure is generated between the sliding members 14c1, 14d1 and the main rope 9 while being positioned at. The braking position P2 is an example of a braking state, and the non-braking position P1 is an example of a non-braking state.

In the present embodiment, for example, the gap between the two sliding members 14c1 and 14d1 is opened in the opposite direction in the Y direction. The main rope 9 can be replaced with the braking mechanism 14 by being inserted from the open portion of the gap when the main rope 9 is replaced.

Further, in the present embodiment, the sliding members 14c1 and 14d1 are made of hard wood that is more flexible than the main rope 9 like the sliding members 13e2 and 13f2. As a result, the load on the main rope 9 during braking is reduced.

Further, the fixed portion 14d is supported so as to be movable in the X direction with respect to the base 14a, for example. In the present embodiment, for example, by tightening the braking force adjusting screw 14e, the fixing portion 14d approaches the movable portion 14c, and by extension, the braking force when the lever 14b is operated can be increased.

As shown in FIG. 2, the braking mechanism 14 is located below, for example, each of the rope guides 12. In other words, the braking mechanism 14 is interposed at both ends of the transport path 20. Further, in the present embodiment, one braking mechanism 14 is attached to each of the columns 11a. The number of braking mechanisms 14 is not limited to this example, and may be, for example, one or three or more.

For example, the main rope 9 is attached to the braking mechanism 14 so as to be sandwiched from the X direction and the opposite direction. Then, in the present embodiment, the main rope 9 is braked by the movement of the braking mechanism 14 from the non-braking position P1 to the braking position P2, and thus the transportation of the main rope 9 is stopped. The braking mechanism 14 is also referred to as a stop brake or the like.

For the movement of the braking mechanism 14 between the non-braking position P1 and the braking position P2, for example, the operator may manually operate the lever 14b, or the lever 14b may be operated by an electric actuator or the like. ..

Next, a method of exchanging the main rope 9 using the main rope transport device 10 will be described. 6 to 9 are schematic configuration diagrams for explaining a method of exchanging the main rope 9 using the main rope transport device 10, and FIG. 7 is a diagram showing a state after FIG. 6, and FIG. 8 is a diagram showing a state after FIG. Is a diagram showing a state after FIG. 7, and FIG. 9 is a diagram showing a state after FIG. 8.

First, as shown in FIG. 1, the main rope transfer device 10 is installed around the hoisting machine 6 of the elevator 1 (S1). S1 is an example of the first step. S1 is conveyed by, for example, a step of aligning the frame 11 with respect to the hoisting machine 6 (folding portion 9a), or by attaching a rope guide 12, a resistance mechanism 13, and a braking mechanism 14 to the frame 11. A step of adjusting the route 20 and the like are included.

Next, as shown in FIG. 6, the car 4 is lifted from the machine room 2 by a chain block or the like to relax the existing main rope 9E wound around the hoisting sheave 7 and the deflecting sheave 8. Then, the main rope 9E is replaced with the rope guide 12, the resistance mechanism 13, and the braking mechanism 14 of the main rope transport device 10 (S2). S2 is an example of the second step.

In S2, the step of attaching the existing main rope 9E into the guide rail 12a of the rope guide 12, the step of sandwiching the main rope 9E between the two sliding members 13e2 and 13f2 of the resistance mechanism 13, and braking the main rope 9E. The step of attaching between the two sliding members 14c1 and 14d1 of the mechanism 14 is included.

Next, as shown in FIG. 7, one end of the existing main rope 9E was removed from the rope stopper 25 (see FIG. 6) and wound around the rope transmitter 28 installed at the landing 21 on the top floor. Connect with the newly installed main rope 9N (S3). In FIG. 7, reference numeral 9c is a connection portion between the existing main rope 9E and the newly installed main rope 9N.

Further, the other end of the existing main rope 9E is removed from the rope stopper 26 (see FIG. 6) and wound around the rope winder 22 installed at the landing 21 (S4). In this case, for example, by holding the other end of the existing main rope 9E from the machine room 2 with the rope descent stopper 27, it is possible to prevent the main rope 9E from falling.

Next, as shown in FIGS. 7 and 8, the rope guide 12 and the resistance mechanism 13 are formed by sending out the new main rope 9N from the rope delivery machine 28 while winding the existing main rope 9E with the rope winder 22. , And the main rope 9 (9E, 9N) is conveyed via the braking mechanism 14 (S5).

At this time, by braking the main rope 9 (9E, 9N) by the resistance mechanism 13 and the braking mechanism 14, the main rope 9 is accelerated by its own weight, for example, between the rope guide 12 and the sheave 24 of the counterweight 5. Can be suppressed. S3 to S5 are examples of the third step.

Next, as shown in FIG. 9, the replaced new main rope 9N is removed from the rope guide 12, the resistance mechanism 13, and the braking mechanism 14 and hung back on the hoisting sheave 7 and the deflecting sheave 8 (S6).

Next, one end of the newly installed main rope 9N is removed from the rope transmitter 28 and fixed to the rope stopper 25 (S7).

Next, the connection portion 9c (see FIG. 8) between the other end of the new main rope 9N and the existing main rope 9E is released, the total length of the new main rope 9N is adjusted, and then fixed to the rope stopper 26. (S8).

Then, the rope descent stopper 27 (see FIG. 8) is removed from the newly installed main rope 9N, and the chain block or the like is removed from the car 4 (S9).

Finally, the rope guide 12, the resistance mechanism 13, and the braking mechanism 14 are attached from the frame body 11 and disassembled, and the main rope transport device 10 is removed (S10).

As described above, in the present embodiment, for example, the main rope transfer device 10 includes a frame body 11 provided around the hoisting machine 6 of the elevator 1 and a main rope 9 wound around the hoisting machine 6. A rope guide 12 that is movably attached to the frame 11 and supports the main rope 9 so as to be movable along the transport path 20, and is slidably attached to the frame 11 with the main rope 9 intervening in the transport path 20. A braking mechanism attached to the frame 11 so as to be able to switch between the braking position P2 (braking state) and the non-braking position P1 (non-braking state) sandwiching the main rope 9 between the resistance mechanism 13 and the transport path 20. 14 and.

According to such a configuration, for example, the resistance mechanism 13 and the braking mechanism 14 can prevent the main rope 9 from accelerating due to its own weight when the main rope 9 is conveyed via the rope guide 12. Therefore, for example, the main rope 9 is prevented from coming off or falling from the rope guide 12, and the replacement work of the main rope 9 can be performed more safely or more reliably.

Further, in the present embodiment, for example, the braking mechanism 14 and the resistance mechanism 13 face the main rope 9 and have sliding members 14c1, 14d1 and sliding members 13e2, 13f2, respectively, which are made of wood. ..

According to such a configuration, for example, the sliding members 14c1, 14d1, 13e2, 13f2 can suppress the acceleration of the main rope 9, and can suppress the damage of the main rope 9 during braking or deceleration. Or, the winding load of the main rope 9 can be reduced.

Further, in the present embodiment, for example, the rope guide 12 has flexibility and is configured to be deformable along the main rope 9.

According to such a configuration, for example, the deformable rope guide 12 tends to increase the degree of freedom of the transport path 20, and thus the size of the hoist 6 such as the width in the X direction is different. It is possible to obtain the main rope transfer device 10 that easily corresponds to 1. Further, for example, the acceleration of the main rope 9 can be suppressed by the sliding resistance between the rope guide 12 and the main rope 9.

[Modification example]
FIG. 10 is a configuration diagram of the main rope transport device 10A of the modified example, and is a view in a state where the resistance mechanism 13 and the braking mechanism 14 are removed. The main rope transfer device 10A has the same configuration as the main rope transfer device 10 of the above embodiment. Therefore, the main rope transfer device 10A can obtain the same operations and effects as those in the above embodiment based on the same configuration.

However, in this modified example, as shown in FIG. 10, the frame body 11 has a height adjusting mechanism 15 capable of adjusting the height position in the Z direction with respect to the hoisting machine 6 (see FIG. 2). However, it is different from the above embodiment.

The height adjusting mechanism 15 has, for example, a lower support column 11d, an upper support column 11e, and a coupling tool 16. That is, in this modification, the support column 11a is composed of a lower support column 11d and an upper support column 11e as two divided bodies divided in the Z direction. The number of divisions of the support column 11a is not limited to two, and may be, for example, three or more.

The lower strut 11d and the upper strut 11e are provided with a plurality of openings 11d1, 11e1 at intervals in the Z direction, respectively. The openings 11d1, 11e1 are, for example, round holes penetrating the lower column 11d and the upper column 11e in the Y direction.

The binder 16 is, for example, a bolt and a nut. The binder 16 is coupled with two openings 11d1, 11e1 arranged (overlapping) in the Y direction.

The height adjusting mechanism 15 can adjust the height (total length) of the support column 11a in the Z direction by moving the lower support column 11d and the upper support column 11e relatively along the Z direction. Then, the frame body 11 can be held at a plurality of height positions by fastening the coupling tool 16 to the pair of the openings 11d1, 11e1 that change according to the height of the support column 11a.

As described above, in this modification, for example, the frame body 11 has a height adjusting mechanism 15 capable of adjusting the height position of the frame body 11 in the Z direction with respect to the hoisting machine 6.

According to such a configuration, the height position of the frame 11 in the Z direction can be adjusted by the height adjusting mechanism 15, so that, for example, the hoisting machine 6 can be used for elevators 1 having a plurality of specifications having different heights. An easy main rope transfer device 10A can be obtained.

The frame body 11 is not limited to this example, and may have, for example, a width adjusting mechanism capable of adjusting the width of the frame body 11 in the X direction with respect to the hoisting machine 6. In this case, the width adjusting mechanism can have, for example, two beams 11b (divided bodies) divided in the X direction and a coupling tool 16.

According to such a configuration, the width of the frame 11 in the X direction can be adjusted by the width adjusting mechanism. Therefore, for example, the main rope that easily corresponds to the elevator 1 having a plurality of specifications having different widths in the X direction of the hoist The transport device 10A can be obtained.

Although the embodiments and modifications of the present invention have been illustrated above, the above-described embodiments and modifications are examples, and the scope of the invention is not intended to be limited. The above-described embodiment and modification can be implemented in various other forms, and various omissions, replacements, combinations, and changes can be made without departing from the gist of the invention.
