  DESCRIPTION OF EMBODIMENTS Hereinafter, an embodiment of an elevator rope hanging method according to the present invention and a rope hanging jig used therefor will be described in detail with reference to the drawings.

  First, the rope hanging jig 10 will be described with reference to FIGS. 1 and 2. FIG. 1 is a front view of a rope hanging jig 10 and FIG. 2 is a plan view thereof.

  In these drawings, the rope hanging jig 10 has a gantry 11. As will be described later, the gantry 11 is configured to be installed on an elevator car or a work gondola provided in a hoistway. On this gantry 11, first and second temporary sheaves (hereinafter referred to as dummy sheaves) 12, 13, rope supply drums 14, 15, 16, a locking portion 17 that locks one end of the rope. Are provided.

  The first dummy sheave 12 is provided on one side of the gantry 11 as viewed from above (near the left side in the figure), and rotates along this one side (left side: a direction perpendicular to the paper surface of FIG. 1)). It has a shaft 12A and is rotatably supported by a bearing 12B. On the outer periphery of the first dummy sheave 12, a plurality of ropes 18 are wound from the drums 14, 15, and 16 in a parallel state along the one side. The rope 18 is sent out in the length direction downward in the figure.

  The plurality of drums 14, 15, 16 have rotation shafts 14 A, 15 A, 16 A that are parallel to the rotation shaft 12 A of the first dummy sheave 12, respectively, and can be rotated on the gantry 11 by corresponding bearings 14 B, 15 B, 16 B, respectively. Is installed. A rope 18 is wound around each of the drums 14, 15, and 16, and each end of these ropes can be pulled out toward the first dummy sheave 12 by the rotation.

  Here, as shown in FIG. 2, each of the drums 14, 15, and 16 has three rope winding portions, and three ropes for each drum, a total of nine ropes 18 in parallel. It can be sent to the first dummy sheave 12. In this case, the installation position on the gantry 11 is set so that the ropes 18 drawn from the drums 14, 15, 16 do not interfere with each other until reaching the first dummy sheave 12. That is, the first dummy sheave 12 is disposed between a rope (18a) fed out from the drum 14 and a rope (18b) fed out from the drum 15 in the height direction. , 18b can be drawn out from the first dummy sheave 12 without interfering with each other. The drum 16 is disposed at a position higher than the drums 14 and 15 and between the drums 14 and 15 in the front-rear direction (the left-right direction in the drawing). Thus, the drawn-out rope (referred to as 18c) does not buffer with the other ropes 18a and 18b, and the installation space on the gantry 11 can be shortened. Therefore, even when the number of ropes increases, the overall dimensions of the rope hooking jig 10 can be reduced.

  The second dummy sheave 13 has a rotation shaft 13A parallel to the rotation shaft 12A of the first dummy sheave 12, and is rotatably installed on the gantry 11 by a bearing 13B. The second dummy sheave 13 is provided on the gantry 11 on the other side (near the right side in the figure) facing the one side, and is fed out from the drums 14, 15, 16, and the first dummy sheave 13. 12, a rope wound around a sheave for lifting support of an elevator car located below (not shown) is wound instead of the sheave of a hoisting machine.

  Further, the locking portion 17 for locking one end portion of the rope 18 is provided near the right side in the figure on the gantry 11 like the second dummy sheave 13 and, as will be described later, One end of the rope 18 wound around the supporting sheave is locked.

  In this way, the first and second dummy sheaves 12 and 13, the plurality of drums 14, 15 and 16 for supplying the rope, and the locking portion 17 for locking one end of the rope are arranged on the mount 11. 10, in particular, by arranging a plurality of drums 14, 15 and 16 rationally in the front and rear (left and right in the figure) and up and down, even if the number of ropes 18 to be handled is large, the total occupied area can be reduced, It can be configured in a shape that can be mounted on a car or a working gondola inside.

  Next, the case where a rope is hooked in a hoistway using such a rope hooking jig 10 will be described. First, as shown in FIG. 3, the case where the rope hanging jig 10 is installed on the elevator car 21 and is roped will be described. FIG. 3 is a schematic view showing a state when the rope hanging jig 10 is placed on the car 21.

  In FIG. 3, a car 21 is assembled in a hoistway, and two sheaves (hereinafter referred to as car sheaves) 22 for supporting suspension are provided on the lower surface thereof. The rope hooking jig 10 locks the first and second dummy sheaves 12 and 13, a plurality of drums 14 and 15 for supplying rope, and one end of the rope on a gantry 11 mounted on the upper surface of the car 21. The locking part 17 is attached by the arrangement configuration described above. 1 and 2 show the three drums 14, 15, and 16 for supplying the rope, but FIG. 3 shows a case in which the two drums 14 and 15 are attached to simplify the explanation. . In general, the number of ropes 18 varies depending on the rated load capacity of the elevator and the like, and in the case where only two drums 14 and 15 are used, it is actually possible.

  Next, with reference to FIGS. 4 and 5, a description will be given of a rope hanging method when the rope hanging jig 10 is installed on the elevator car 21 and is roped. FIG. 4 is a flowchart for explaining the procedure of the rope hanging method, and FIG. 5 schematically shows the operation of each step described in FIG.

  4 and 5, first, it is assumed that the installation work of various articles in the hoistway has been completed (step 401). That is, the rope hitches 26 and 27 and the hoisting machine 28 are installed in the upper part of the hoistway 25 shown in FIG. 5, and although not shown, a guide rail for a car and a guide rail for a counterweight are installed. Furthermore, it is assumed that a lifting machine for rope hanging work is also installed.

  Next, the car frame of the car 21 is assembled in the hoistway 25 (step 402). The car 21 has the structure shown in FIG. 3, and two car sheaves 22 are provided on the lower surface thereof. The counterweight 29 is also installed in the hoistway 25. As shown in FIG. 5, the counterweight 29 has a sheave 30 (hereinafter referred to as a C / W sheave) 30 for supporting the suspension at the top.

  Next, as shown in FIG. 5A, the rope hooking jig 10 is installed on the upper surface of the car 21 in the hoistway 25 (step 403). At this time, the car 21 and the counterweight 29 are both located at the lowest position in the hoistway 25. Here, when the rope hanging jig 10 is installed on the car 21, the first dummy sheave 12 has the same position on the vertical projection plane as one of the car sheeps 22 provided on the lower surface of the car 21. Position it so that This is a configuration for drawing out the rope without interfering with the side surface of the car 21 and the like when the car 21 is lifted as will be described later.

  In this state, the worker who has entered the rope hooking jig 10 moves the rope lifting jig 32 from the vicinity of the second dummy sheave 13 located on the hoisting machine 28 side to the hoistway 25 as shown by B in FIG. (Step 404). As will be described later, the rope pulling jig 32 holds the tip of the rope 18 fed from the drums 14 and 15 on the rope hooking jig 10, and as shown in FIG. The tip portions of the plurality of ropes 18 are sandwiched by the sandwiching plates 32b provided on the surface. Further, the plate 32a is provided with a hole 32c for attaching a tool (not shown) for the lifting operation.

  Next, the worker pulled out one end of the rope 18 from each of the drums 14 and 15 on the rope hanging jig 10, and was provided on the lower surface of the car 21 from the first dummy sheave 12 as shown by C in FIG. It is drawn around the car sheave 22 and wrapped around them (step 405). Then, one end of these ropes 18 is fixed to a rope pulling jig 32 previously lowered into the hoistway 25 as shown by D in FIG. 5 (step 406), and then pulled up onto the rope hanging jig 10 on the cage (step 406). Step 407).

  The worker wraps the pulled rope 18 around the second dummy sheave 13 clockwise as shown by E in FIG. 5 (step 408). Thereafter, the rope 18 is further drawn around the C / W sheave 30 of the counterweight 29 located on the side of the car 21 at the lowest position in the hoistway 25 and wound counterclockwise in the figure (step 409). ), One end is locked to the locking portion 17 of the rope hanging jig 10 and fixed (step 410).

  Next, as shown by F in FIG. 5, with the counterweight 29 fixed to the lowermost part of the hoistway 25, the car 21 is lifted up to the uppermost part of the hoistway 25 by a lifting machine (not shown). As the elevator car 21 is lifted, the rope hanging jig 10 fixed to the upper part thereof is also lifted, so that the rope 18 whose one end is locked to the locking portion 17 on the rope hanging jig 10 is located at the lowest position. The drums are fed out from the corresponding drums 14 and 15 through the C / W sheave 30, the second dummy sheave 13 to be lifted, the car sheave 22, and the first dummy sheave 12 (step 411).

  In this way, when the car 21 reaches the uppermost part in the hoistway 25, the car 21 is stopped at this uppermost position, and an operator on the rope hanging jig 10 can move as shown by G in FIG. The rope 18 wound around the second dummy sheave 13 is replaced with the drive sheave of the hoisting machine 28 provided at the upper part of the hoistway 25 (step 412). Further, one end of the rope 19 locked on the rope hooking jig 10 is fixed to the rope hitch 27 provided on the upper part of the hoistway 25 (step 413). Further, by fixing the other end of the drums 14 and 16 to the rope hitch 26 provided at the upper part of the hoistway 25 (step 414), the rope-hanging operation is completed as indicated by H in FIG.

  Here, when the car sheep 30 attached to the car 21 is the lower part of the car 25, generally, the rope hanging around the car must be finished when the car 25 is located at the lower part of the hoistway. Don't be. Therefore, in the conventional rope hanging, it is necessary to carry out by placing the counterweight in the upper part of the hoistway and the cage in the lower part of the hoistway. However, in the case of an elevator that does not have a machine room and equipment (rope fixing parts, control panel) is installed in the upper part of the hoistway, the rope fixing work and the elevator trial operation work must be performed in the upper part of the hoistway. In addition, it was necessary to install a work floor (aerial scaffolding, etc.) at the top of the hoistway.

  On the other hand, in the above embodiment of the present invention, the rope routing around the car 21 including the counterweight 29 is completed in the lower part of the hoistway 25 in the steps from step 404 to step 410. Thereafter, since the car 21 is lifted upward, the car ceiling after the car is lifted can be used as a work floor. In this way, the work of installing a separate work floor at the upper part of the hoistway can be omitted. Further, when the car 21 is lifted, a plurality of ropes 18 can be fed simultaneously from the drums 14 and 15 of the rope hanging jig 10 installed on the car 21. Then, after lifting the car 21 to the uppermost position of the hoistway 25, as described above, using the ceiling portion of the car 21 as a work floor, changing the rope 18 fed to the hoisting machine 28, Since the fixing work to the hitch parts 26 and 27 at the ends can be performed, the rope hanging work of the elevator can be greatly simplified and simplified as compared with the conventional one.

  Further, this rope hanging work can be performed entirely in the hoistway 25. For this reason, unlike conventional ones, a rope bundle or a rope supply drum is installed on an elevator hall on a certain floor, so that other workers are not disturbed. Moreover, the ropes 14 and 15 for supplying the rope are installed on the rope hanging jig 10 on the car 21, and since there is always a rope hanging worker on the jig 10, the drums 14 and 15 are temporarily Even if a problem occurs in the rope feeding out, the worker can immediately find and deal with this problem, and the rope hanging work can be further ensured.

  Next, a rope hanging method when the rope hanging jig 10 is installed on a work gondola located above the elevator car 21 and is roped will be described with reference to FIGS. FIG. 6 is a flowchart for explaining the procedure of the rope hanging method, and FIG. 7 schematically shows the operation of each step described in FIG.

  6 and 7, first, it is assumed that the installation of various articles in the hoistway and the lifting of the counterweight (C / W) to the top of the hoistway 25 have been completed (step 601). . That is, the rope hitches 26 and 27 and the hoisting machine 28 are installed in the upper part of the hoistway 25 shown in FIG. 7, and although not shown, a guide rail for a car and a guide rail for a counterweight are installed. In addition, a lifting machine for rope hanging work is also installed. With this lifting machine, as shown by A in FIG. 7, the lifting of the counterweight 29 to the uppermost position of the hoistway 25 is completed and fixed. It is assumed that The counterweight 29 has a C / W sheave 30 for suspension support at the top.

  Next, the car frame of the car 21 is assembled in the hoistway 25 (step 602). The assembled car 21 is located at the lowest position in the hoistway 25. The car 21 is assumed to have two car sheaves 22 on the lower surface.

  Above the car 21 located at the lowest position in the hoistway 25, as shown by A in FIG. 7, a working gondola 35 is provided so that it can be lifted. Then, the rope hooking jig 10 described above is installed (step 603). This rope hanging jig 10 has basically the same structure as that shown in FIG. 3, but the second dummy sheave 13 is not used in the rope hanging method using a gondola, so the second dummy sheave is removed. It may be a structure. Further, in the state where the rope hanging jig 10 is installed on the gondola 35, the first dummy sheave 12 is arranged on one side of the car sheep 22 provided on the lower surface of the car 21 positioned below and on the vertical projection plane. Position them so that they are in the same position. This is a configuration for feeding the rope without interfering with the side surface of the car 21 and the like when the gondola 35 is lifted as will be described later.

  In this state, the worker who gets on the gondola 35 lowers the rope pulling jig 32 from the right side of the gondola into the hoistway 25 as shown by B in FIG. 7 (step 604). The rope pulling jig 32 holds the tip of the rope 18 and is shown in FIG.

  Next, the worker pulls out one end of the rope 18 from each of the drums 14 and 15 on the rope hooking jig 10, and as shown by C in FIG. 7, the lower surface of the car 21 positioned below from the first dummy sheave 12. Are wound around the car sheaves 22 provided on the belt (step 605). Then, one end of these ropes 18 is fixed to the rope pulling jig 32 previously lowered into the hoistway 25 as shown by D in FIG. 7 (step 606), and then lifted onto the gondola 35 (step 607). As shown by E of 7, it is fixed to the locking portion 17 of the rope hooking jig 10 (step 608).

  Next, as shown by F in FIG. 7, the gondola 35 is lifted up to the top of the hoistway 25 by a lifting machine (not shown) with the car 21 fixed to the lowermost part of the hoistway 25. Since the rope hanging jig 10 is also lifted by the lifting of the gondola 35, the rope 18 having one end fixed to the locking portion 17 on the rope hanging jig 10 can be accommodated via the car sheave 30 and the first dummy sheave 12. The drums 14 and 15 are fed out (step 609).

  In this way, when the gondola 35 reaches the uppermost position in the hoistway 25, the gondola 35 is stopped at the uppermost position, and the operator on the rope hanging jig 10 fixes the rope fixed to the rope lifting jig 32. The tip of 18 is removed from the rope hanging jig 10, and as shown by G in FIG. 7, it is wound clockwise around the driving sheave of the hoisting machine 28 provided at the upper part of the hoistway 25, and further the C / W sheave. 30 is wound counterclockwise in the figure (step 610). Thereafter, the end of the rope 18 is socketed and fixed to the rope hitch 27 (step 611). Further, the other end on the drum 14 and 16 side is fixed to the rope hitch 26 provided on the upper part of the hoistway 25 (step 612), thereby completing the rope hooking operation as indicated by H in FIG.

  Also in this embodiment, in the steps from step 604 to step 608, the rope routing around the car 21 is completed at the lower part of the hoistway 25, and then the gondola 35 is lifted to the upper part. The later gondola 35 can be used as a work floor. In this way, the work of installing a separate work floor at the upper part of the hoistway can be omitted. Further, when the gondola 35 is lifted, a plurality of ropes 18 can be fed out simultaneously from the drums 14 and 15 of the rope hanging jig 10 installed on the gondola 35. Then, after the gondola 35 is lifted to the uppermost position of the hoistway 25, as described above, the gondola 35 is used as a work floor to the drive sheave of the hoisting machine 28 and the C / W sheave 30 of the unwound rope 18. As a result, it is possible to carry out the operation of fixing the end of the rope to the hitch portions 26 and 27, so that the rope operation of the elevator can be greatly simplified and simplified as compared with the conventional one.

  Further, this rope hanging work can be performed entirely in the hoistway 25. For this reason, unlike the prior art, installing a rope bundle or rope supply drum on a hall floor on a certain floor does not cause trouble to other workers. Also, the rope supply drums 14 and 15 are installed on the rope hanging jig 10 on the gondola 35, and there is always a rope operator on the jig 10. Even if a trouble occurs in the rope feeding, the worker can immediately find and deal with this trouble, and the rope hanging work can be further ensured.
