  As shown in FIG. 3, the installation jig 20 according to the present embodiment includes a jig main body 21 and a suspended lower portion 22 provided on the upper surface of the jig main body 20. Among these, the jig body 21 is formed in a rectangular shape that extends in the horizontal direction when a projecting portion 24 to be described later contacts the ceiling 2a of the hoistway 2 (the floor of the machine room 7). In this case, the jig body 21 can be formed by, for example, a square pipe-shaped member, or can be formed in a square pipe shape by welding two groove steels facing each other. Note that FIG. 3 shows a state in which the jig main body 21 is horizontally disposed for the sake of convenience, although a contact portion 24 described later is separated from the ceiling 2a of the hoistway 2 (described later). The same applies to FIG. 5). In this state, the jig body 21 according to the present embodiment is formed in a rectangular shape so that its longitudinal direction extends in the horizontal direction. In the present specification, terms indicating directions such as “upper”, “lower”, and “upper” are based on the assumption that the installation jig 20 is arranged in the state shown in FIG. Shall be used.

  The suspended lower part 22 is configured to be suspended from the lifting machine 10. In the present embodiment, the suspended lower part 22 is connected to the lifting machine 10 via a lifting machine side chain 11 (lifting machine side suspension member). The lifting machine 10 is installed in a machine room 7 provided above the hoistway 2. It is preferable that the lifting machine side chain 11 passes through a main rope hole 13 provided in the ceiling 2a of the hoistway 2 (the floor of the machine room 7). The main rope hole 13 is a hole through which the existing main rope 4a, which has been wound up by the existing hoisting machine 6a installed in the machine room 7, in the elevator apparatus 1a before renewal shown in FIG. ing.

  The lower surface of the jig body 21 is provided with a hoisting machine suspension 23 for suspending the new hoisting machine 6b. The newly installed hoisting machine 6b is connected to the hoisting machine suspension 23 via the hoisting machine side chain 12 (hoisting machine side hanging member) and is suspended from the installation jig 20.

  Two protrusions 24 protrude upward from the upper surface of the jig body 20. These protrusions 24 can come into contact with the ceiling 2 a of the hoistway 2 when the installation jig 20 is lifted on the upper part of the hoistway 2. More specifically, the upper surface 24a of the protrusion 24 can abut on the ceiling 2a. The two protrusions 24 are spaced apart from each other in the horizontal direction, and are arranged at both ends in the longitudinal direction of the jig body 21 in the form shown in FIG.

  The suspended lower part 22 is a direction perpendicular to the direction from the one projecting part 24 to the other projecting part 24 (the left-right direction in FIG. 3), and when viewed in the horizontal direction, the one projecting part 24 and the other projecting part 22 It arrange | positions between the protrusion parts 24. FIG. That is, the suspended lower part 22 is disposed between the two protrusions 24 when viewed in a direction perpendicular to the paper surface of FIG. The suspended lower part 22 is arranged at a position shifted from the horizontal center of the jig body 21 (position shifted from the center to the right side in the embodiment shown in FIG. 3).

  The hoisting machine suspending portion 23 is disposed at one end of the jig body 21 (on the right side in the embodiment shown in FIG. 3). In the form shown in FIG. 3, the jig body 21 is disposed below the protrusion 24 disposed at the right end.

  Next, the operation of the present embodiment configured as described above will be described. Here, an installation method for lifting and installing the new hoisting machine 6b on the upper part of the hoistway 2 when the elevator apparatus 1a shown in FIG. 1 is renewed to the elevator apparatus 1b shown in FIG.

  First, as shown in FIG. 3, the lifting machine 10 is installed in the machine room 7. The existing hoisting machine 6a (see FIG. 1) installed in the machine room 7 and the existing main rope 4a wound up by the existing hoisting machine 6a have already been removed at the time of installing the lifting machine 10. It is preferred that

  Subsequently, the installation jig 20 is suspended from the lifting machine 10, and the new hoisting machine 6 b is suspended from the installation jig 20.

  In this case, first, an installation jig 20 having two projecting portions 24 projecting upward is prepared.

  Subsequently, the suspended lower part 22 of the installation jig 20 is connected to the lifting machine 10 via the lifting machine side chain 11. As a result, the installation jig 20 is suspended from the lifting machine 10. At this time, it is preferable that the lifting machine side chain 11 passes through the main rope hole 13 provided in the ceiling 2a of the hoistway 2 through which the existing main rope 4a of the elevator apparatus 1a has passed. On the other hand, the newly installed hoisting machine 6 b is connected to the hoisting machine suspension 23 of the installation jig 20 via the hoisting machine side chain 12. As a result, the new hoisting machine 6 b is suspended from the installation jig 20.

  After the installation jig 20 is suspended from the lifting machine 10 and the new hoisting machine 6b is suspended from the installation jig 20, the installation jig 20 and the new hoisting machine 6b are raised by the hoisting machine 10 and installed. The two protrusions 24 of the jig 20 abut on the ceiling 2 a of the hoistway 2.

  In this case, first, until one of the two protrusions 24 of the installation jig 20 comes into contact with the ceiling 2 a of the hoistway 2, the installation jig 20 has a force to be directed upward from the lifting machine 10. In response, the installation jig 20 and the new hoisting machine 6b rise. During this time, as shown in FIG. 4A, the jig body 21 of the installation jig 20 is positioned so that the end of the hoisting machine suspension 23 side is positioned downward by the weight of the new hoisting machine 6b. Lean on. When the installation jig 20 and the new hoisting machine 6b are lifted in such a tilted state, as shown in FIG. 4 (b), one (left side shown in FIG. 4) protruding portion 24 becomes the hoistway 2. Abuts on the ceiling 2a. Even after the one projecting portion 24 comes into contact with the ceiling 2a, the installation jig 20 receives the upward force from the lifting machine 10. As a result, as shown in FIG. 4C, the installation jig 20 is rotated in the counterclockwise direction in FIG. 4 with the contact point between the left protruding portion 24 in contact with the ceiling 2a and the ceiling 2a as a fulcrum. Rotate. For this reason, the inclination of the jig main body 21 of the installation jig 20 gradually decreases, and the new hoisting machine 6b further rises. Thereafter, as shown in FIG. 4D, the other (right side shown in FIG. 4) protrusion 24 comes into contact with the ceiling 2 a of the hoistway 2. As a result, the two protrusions 24 come into contact with the ceiling 2a, and the rotation of the installation jig 20 is stopped. Further, the new hoisting machine 6b reaches the upper part of the hoistway 2, and the ascent of the new hoisting machine 6b stops.

  Thereafter, the new hoisting machine 6b is installed at the installation position of the hoistway 2 in a state where the two protrusions 24 are in contact with the ceiling 2a of the hoistway 2. More specifically, the beam 9 is fixed in advance on a side wall of the hoistway 2 to a bracket fixed using anchor bolts. The new hoisting machine 6b that has reached the upper part of the hoistway 2 is moved onto the beam 9 while being suspended from the installation jig 20. Even in a state where the two protruding portions 24 are in contact with the ceiling 2a, the installation jig 20 receives a force directed upward from the lifting machine 10. Thereby, the attitude | position of the installation jig | tool 20 and the new winding machine 6b which reached the upper part of the hoistway 2 can be stabilized. The new hoisting machine 6 b that has moved onto the beam 9 is attached to the beam 9. In this way, the new hoisting machine 6b is installed at the installation position.

  After the new hoisting machine 6b is installed at the installation position, the installation jig 20 is removed from the new hoisting machine 6b. More specifically, the hoisting machine side chain 12 is removed from the newly installed hoisting machine 6b. Then, the hoisting machine side chain 12, the installation jig 20, and the lifting machine side chain 11 are removed, and the lifting machine 10 is removed.

  In this way, the new hoisting machine 6b is lifted and installed on the upper part of the hoistway 2, and the installation work of the new hoisting machine 6b is completed.

  Thus, according to the present embodiment, the installation jig 20 has the two protruding portions 24 protruding upward from the jig main body 21. Thus, when the installation jig 20 that suspends the newly installed hoisting machine 6b reaches the upper part of the hoistway 2, the two protruding portions 24 can be brought into contact with the ceiling 2a of the hoistway 2. The posture of the installation jig 20 can be stabilized when the installation jig 20 receives the upward force from the lifting machine 10 in a state where the two protrusions 24 are in contact with the ceiling 2a. For this reason, the attitude | position of the installation jig | tool 20 and the new winding machine 6b which reached the upper part of the hoistway 2 can be stabilized. As a result, the efficiency of installing the new hoisting machine 6b on the upper part of the hoistway 2 can be improved and the working time can be shortened. In particular, since the posture of the installation jig 20 and the new hoisting machine 6b reaching the upper part of the hoistway 2 can be stabilized, the new hoisting machine 6b can be smoothly moved to the installation position. For this reason, the efficiency of the installation work of the newly installed hoisting machine 6b in the upper part of the hoistway 2 can be improved.

  Moreover, according to this Embodiment, the lifting machine side chain 11 which connects the installation jig 20 to the lifting machine 10 is provided in the ceiling 2a of the hoistway 2, and the existing main rope 4a of the elevator apparatus 1a before renewal. Has passed through the main rope hole 13. This eliminates the need for providing a new hole in the ceiling 2a in order to allow the lifting machine side chain 11 to pass therethrough. For this reason, the efficiency of the installation work of the newly installed hoist 6b on the upper part of the hoistway 2 can be improved, and the work time can be shortened.

  In the present embodiment described above, after the new hoisting machine 6b is suspended from the installation jig 20, one of the two protrusions 24 of the installation jig 20 contacts the ceiling 2a of the hoistway 2. The contact example has been described. However, the present invention is not limited to this. Before the new hoisting machine 6b is suspended from the installation jig 20, one of the two protrusions 24 is brought into contact with the ceiling 2a. May be. That is, the new hoisting machine 6b may be carried into the hoistway 2 not from the bottom of the hoistway 2 but from the upper part or the vicinity thereof. In this case, as shown in FIG. 4B, the new hoisting machine 6 b may be suspended from the installation jig 20 after one projecting portion 24 is brought into contact with the ceiling 2 a. In this state, when the installation jig 20 receives a force directed upward from the lifting machine 10, the installation jig 20 rotates to raise the new hoisting machine 6 b as shown in FIG. It is possible to improve the efficiency of installation work of the new hoisting machine 6b on the upper part of the hoistway 2.

(Second Embodiment)
Next, an elevator hoist installation jig and an elevator hoist installation method according to the second embodiment of the present invention will be described with reference to FIG.

  The second embodiment shown in FIG. 5 is mainly different in that a steadying member that contacts the side wall of the hoistway is provided at both ends of the jig main body. This is substantially the same as the first embodiment shown in FIG. In FIG. 5, the same parts as those of the first embodiment shown in FIGS. 1 to 4 are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIG. 5, in the present embodiment, an anti-sway member 30 that contacts the side wall 2 b of the hoistway 2 is provided at both ends of the jig body 21. It is preferable that this steadying member 30 is detachably attached to the jig body 21. In this case, the steadying member 30 can be attached to the jig body 21 after the two protrusions 24 of the installation jig 20 abut on the ceiling 2a of the hoistway 2. Accordingly, the steadying member 30 can be removed from the jig body 21 while the installation jig 20 and the new hoisting machine 6b are raised, and the installation jig 20 and the new hoisting machine 6b can be smoothly moved. It becomes possible to raise it.

  It is preferable that the length of the steady rest member 30 is configured to be adjustable. As a result, after the two projecting portions 24 of the installation jig 20 abut on the ceiling 2a of the hoistway 2, the steadying member depends on the distance between the jig body 21 and the side wall 2b of the hoistway 2. The length of 30 can be adjusted. For this reason, the steadying member 30 can be contact | abutted more reliably by the side wall 2b of the hoistway 2, and the attitude | position of the installation jig 20 and the newly installed hoisting machine 6b can be stabilized further.

  The steadying member 30 may be attached to both ends of the jig body 21 in the longitudinal direction (left and right direction in FIG. 5), but is not limited thereto. For example, the jig body 21 may be attached in the front-rear direction (depth direction). Also in this case, the installation jig 20 can be steady, and the posture of the installation jig 20 can be stabilized.

  As described above, according to the present embodiment, the steadying member 30 that abuts against the side wall 2 b of the hoistway 2 is provided at both ends of the jig main body 21. As a result, it is possible to prevent the installation jig 20 from which the newly installed hoist 6b is suspended from shaking (shaking). For this reason, the attitude | position of the installation jig | tool 20 can be stabilized further. As a result, the efficiency of the installation work of the new hoisting machine 6b above the hoistway 2 can be further improved, and the work time can be further shortened.

  In the above-described embodiment, the example in which the steadying member 30 is detachably attached to the jig body 21 has been described. However, the present invention is not limited to this, and the steadying member 30 may be mounted inside the jig main body 21. In this case, after the two protrusions 24 of the installation jig 20 come into contact with the ceiling 2a of the hoistway 2, the steady member 30 advances to the side wall 2b of the hoistway 2 and comes into contact with the side wall 2b. You may do it.

(Third embodiment)
Next, an elevator hoist installation jig and an elevator hoist installation method according to the third embodiment of the present invention will be described with reference to FIG.

  The third embodiment shown in FIG. 6 is mainly different in that the height of the protruding portion can be adjusted separately, and the other configuration is the same as that of the first embodiment shown in FIGS. It is almost the same as the form. In FIG. 6, the same parts as those of the first embodiment shown in FIGS. 1 to 4 are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIGS. 6A and 6B, in the present embodiment, the height of each protrusion 24 of the installation jig 20 can be adjusted separately.

  More specifically, as shown in FIGS. 6A and 6B, the protrusion 24 is provided on the main body side member 41 provided on the jig main body 21 side and the ceiling 2 a side of the hoistway 2. And a ceiling-side member 42 provided. Among these, the main body side member 41 and the ceiling side member 42 are preferably formed in a pipe shape (preferably a square pipe shape). And at least one part of the ceiling side member 42 is accommodated in the main body side member 41, and the main body side member 41 and the ceiling side member 42 are mutually slidable. The height of the projecting portion 24 can be adjusted by moving the ceiling side member 42 toward the ceiling 2a or retracting the ceiling side member 42 into the main body side member 41. More specifically, the main body side member 41 and the ceiling side member 42 are fixed by pins 43. The main body side member 41 is provided with pin holes 44 through which the pins 43 are inserted, and the ceiling side member 42 is provided with a plurality of similar pin holes 45. As a result, the height of the projecting portion 24 is set to a desired height by mounting the pin 43 by matching the position of the pin hole 44 of the main body side member 41 with the position of the pin hole 45 of the ceiling side member 42. Can be adjusted.

  Since the main body side member 41 is formed in a pipe shape, a main body side plate 46 is attached to the lower surface of the main body side member 41. Thus, the pipe-shaped main body side member 41 can be easily and reliably attached to the jig main body 21. Further, since the ceiling side member 42 is also formed in a pipe shape, a ceiling side plate 47 is attached to the upper surface of the ceiling side member 42. As a result, the ceiling side plate 47 abuts on the ceiling 2a of the hoistway 2 to stabilize the posture of the jig body 21.

  Thus, according to this Embodiment, each height of the protrusion part 24 of the installation jig 20 can be adjusted separately. Accordingly, when the two protrusions 24 are brought into contact with the ceiling 2a of the hoistway 2, the height of each protrusion 24 can be adjusted separately. For this reason, even if unevenness is formed on the ceiling 2a, the jig body 21 of the installation jig 20 can be oriented in the horizontal direction. For this reason, the efficiency of the installation work of the newly installed hoist 6b on the upper part of the hoistway 2 can be further improved.

  In the above-described embodiment, an example in which at least a part of the ceiling side member 42 is accommodated in the main body side member 41 has been described. However, the present invention is not limited to this, and at least a part of the main body side member 41 may be accommodated in the ceiling side member 42. Moreover, although the example in which the pin hole 45 of the ceiling side member 42 was provided with two or more was demonstrated, it is not restricted to this, The pin hole 44 of the main body side member 41 may be provided with two or more. Furthermore, if the height of the protrusion 24 is adjustable, the structure of the protrusion 24 is arbitrary.

(Fourth embodiment)
Next, an elevator hoist installation jig and an elevator hoist installation method according to the fourth embodiment of the present invention will be described with reference to FIG.

  The fourth embodiment shown in FIG. 7 is mainly different in that the projecting portion has a plurality of projecting portion divided bodies whose heights can be adjusted separately. This is substantially the same as the first embodiment shown in FIG. In FIG. 7, the same parts as those of the first embodiment shown in FIGS. 1 to 4 are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIG. 7, in the present embodiment, each of the projecting portions 24 of the installation jig 20 has a plurality of (here, four) projecting portion divided bodies 50 that are separated from each other. The height of each of the protruding portion divided bodies 50 can be adjusted separately.

  More specifically, as shown in FIG. 7, the projecting portion split body 50 includes a main body side split member 51 provided on the jig main body 21 side and a ceiling provided on the ceiling 2 a side of the hoistway 2. Side split member 52. Among these, the main body side dividing member 51 and the ceiling side dividing member 52 are preferably formed in a pipe shape (preferably a square pipe shape). And at least one part of the ceiling side division member 52 is accommodated in the main body side division member 51, and the main body side division member 51 and the ceiling side division member 52 are mutually slidable. The height of the projecting part split body 50 can be adjusted by moving the ceiling side split member 52 toward the ceiling 2a or by retracting it into the main body side split member 51. More specifically, the main body side dividing member 51 and the ceiling side dividing member 52 are fixed by pins 53. The main body side split member 51 is provided with pin holes 54 through which the pins 53 are inserted, and the ceiling side split member 52 is provided with a plurality of similar pin holes 55. Accordingly, the height of the projecting part divided body 50 is obtained by mounting the pin 53 by matching the position of the pin hole 54 of the main body side dividing member 51 and the position of the pin hole 55 of the ceiling side dividing member 52. Can be adjusted to a desired height.

  The four projecting part divided bodies 50 of one projecting part 24 are attached to a single main body side plate 56. Thus, the pipe-like protruding portion divided body 50 can be easily and reliably attached to the jig main body 21. On the other hand, the ceiling side plate 47 as shown in FIG.

  Thus, according to this Embodiment, each height of the protrusion part division body 50 of each protrusion part 24 of the installation jig 20 can be adjusted separately. Accordingly, when the two projecting portions 24 are brought into contact with the ceiling 2a of the hoistway 2, the height of each projecting portion 24, particularly the height of each projecting portion divided body 50, can be adjusted separately. For this reason, even if it is a case where the comparatively fine unevenness | corrugation is formed in the ceiling 2a, the jig | tool main body 21 of the installation jig | tool 20 can be turned to a horizontal direction. For this reason, the efficiency of the installation work of the newly installed hoist 6b on the upper part of the hoistway 2 can be further improved.

  In addition, in this Embodiment mentioned above, the example in which at least one part of the ceiling side division member 52 was accommodated in the main body side division member 51 was demonstrated.
