For example, the end portion of the fixed body 7b is connected to the support member fixed to the foot portion of the support member 4a. For example, the pulling body 7c is a wire. The pulling body 7c is connected to the elevator device 3 from the upper part of the main body 7a via the corresponding pulley device 6.

Next, the pulley device 6 will be described with reference to FIG.
FIG. 3 is a side view of the pulley device of the lifting system of the elevator equipment according to the first embodiment of the present invention.

As shown in FIG. 3, the pulley device 6 includes a return wheel 6e, a connector 6f, a support member 6g, and a nut 6h.

The return wheel 6e is adjacent to the beam member 5a on the central side of the machine room 1. The return wheel 6e includes a groove (not shown).

The return wheel 6e receives the load from the pulling body 7c. The connector 6f receives the load from the return wheel 6e. At this time, the position of the connector 6f is changed according to the load.

Next, the installation procedure of the elevator device 3 will be described with reference to FIG.
FIG. 4 is a flowchart for explaining an installation procedure of the elevator equipment by the lifting system of the elevator equipment according to the first embodiment of the present invention.

As shown in FIG. 4, in step S1, a support device installation step is performed. In the support device installation process, the support device 4 is erected on the floor surface of the machine room 1. After that, the procedure of step S2 is performed. In step S2, the beam device support step is performed. In the beam device support step, the beam device 5 is supported on the upper part of the support device 4. After that, the procedure of step S3 is performed. In step S3, the pulley device support step is performed. In the pulley device support process, a plurality of pulley devices 6 are supported by the beam device 5.

After that, the procedure of step S4 is performed. In step S4, the lifting device installation step is performed. In the lifting device installation step, a main body arranging step, a fixed body fixing step, and a pulling body connecting step are performed.

In the main body arranging step, each main body 7a of the plurality of lifting devices 7 is arranged below the pulley device 6 corresponding to the elevator device 3 on the outside on the vertical projection surface. In the fixed body fixing step, each fixed body 7b of the plurality of lifting devices 7 is fixed in the lower part of the machine room 1. In the pulling body connecting step, each pulling body 7c of the plurality of lifting devices 7 is connected to the elevator device 3 via the corresponding pulley device 6.

After that, the procedure of step S5 is performed. In step S5, the support device extension step is performed. In the support device extension step, the support device 4 is extended in the vertical direction. At this time, the support device 4 is extended until the beam device 5 comes into contact with the ceiling of the machine room 1. As a result, the twisting of the lifting system is suppressed. Therefore, the strength of the lifting system is improved.

After that, the procedure of step S6 is performed. In step S6, the elevator equipment pulling process is performed. In the elevator equipment pulling process, each pulling body 7c of the plurality of lifting devices 7 is wound around the main body 7a. As a result, the plurality of pulling bodies 7c change the horizontal position of the elevator device 3 while pulling up the elevator device 3 by attracting the elevator devices 3 in directions that are inclined with respect to the vertical line and are different from each other. ..

After that, the procedure of step S7 is performed. In step S7, the elevator equipment installation process is performed. In the elevator equipment installation process, each of the pulling bodies 7c of the plurality of lifting devices 7 is separated from the elevator equipment 3 above the support base 2. As a result, the elevator device 3 is installed on the support base 2.

According to the first embodiment described above, the main body 7a of the lifting device 7 is arranged below the pulley device 6 corresponding to the elevator device 3 on the outside on the vertical projection surface. Therefore, it is not necessary to arrange the main body 7a of the lifting device 7 on the upper part of the lifting system. As a result, even when the gap between the elevator device 3 installed in the machine room 1 and the ceiling of the machine room 1 is small, the suspension allowance of the elevator device 3 can be secured to the maximum. Therefore, the elevator device 3 can be pulled up more reliably.

Further, the fixed body 7b of the lifting device 7 is fixed to the lower part of the support member 4a. Therefore, it is not necessary to provide the fixing portion of the fixing body 7b of the lifting device 7 in the machine room 1. As a result, the strength of the lifting system can be improved only by the lifting system.

Further, although the connector 6f is restricted from moving by the support member 6g, its position can be freely changed to some extent according to the load from the return wheel 6e. Therefore, the return wheel 6e can be made parallel to the fixed body 7b and the pulling body 7c.

The return wheel 6a is adjacent to the beam member 5a on the central side of the machine room 1. The return wheel 6a includes a groove (not shown). The groove is formed on the outer peripheral surface of the return wheel 6a. The pedestal 6b rotatably supports the return wheel 6a. The bolt 6c penetrates any through hole of the beam member 5a. One side of the bolt 6c is fixed to the pedestal 6b. The nut 6d is screwed into the other side of the bolt 6c.

With respect to the pulley device 6, the pulling body 7c is wound around a groove on the outer peripheral surface of the return wheel 6a. The return wheel 6a receives the load from the pulling body 7c. The pedestal 6b receives the load from the return wheel 6a. At this time, the pedestal 6b rotates about the bolt 6c according to the load.

According to the second embodiment described above, the suspension allowance of the elevator device 3 can be secured to the maximum as in the first embodiment. Therefore, the elevator device 3 can be pulled up more reliably.
