Between body 13 and traction machine 21.
Fig. 7 is the stereogram of the outline for the stationary state for representing the cage side suspension body connecting portion 24 after Fig. 4 repacking.Change
Cage side suspension body connecting portion 24 after dress is horizontally fixed in upper support 13 near the 2nd car guide rail 8b.And
And cage side suspension body connecting portion 24 is configured at the 2nd car guide rail 8b of the fore-and-aft direction of car 1 rear.
Fig. 8 is the stereogram of the outline for the stationary state for representing the counterweight-side suspension body connecting portion 25 after Fig. 4 repacking.Change
Counterweight-side suspension body connecting portion 25 after dress is flatly erected on the 1st Returning wheel beam 17a and the 2nd Returning wheel beam 17b.Other knots
Structure with repacking before it is identical, but can also as needed with new equipment replacement.
In the method for modifying of such machine-roomless lift, the suspension body 26 during with from surface after repacking is being set
Cage side suspension body connecting portion 16a and the counterweight-side suspension body connecting portion 16b that has set between region by way of, upper
Portion's supporter 13 sets new traction machine 21, it is thus possible to continues to use many equipment to set installation dimension and appearance and size and repacking
Preceding different traction machine 21.Therefore, it is possible to use newest traction machine 21, and realize the shortening of repacking duration.
Further, since traction machine 21 can be configured to the top in hoistway 4, thus even if pit contingency water inlet, traction
Machine 21 will not also make moist.
In addition, the change of layout is less, and the path of suspension body 26 is simpler than before repacking, it is thus possible to reduces to suspension
The damage of body 26.
Further, since it is used as new traction machine 21 using slim traction machine, it is thus possible to the easily top in hoistway 4
The confined space in set traction machine 21.
Embodiment 2
Below, Fig. 9 is the top view for the outline for representing the machine-roomless lift after the repackings of embodiments of the present invention 2.
In embodiment 2, the side in the lowering position that the suspension body 26 after repacking is fallen from the driving rope sheave 23 of new traction machine 21,
As with the suspension body 3 set to the cage side suspension body connecting portion 16a that the has set lifting position identical position risen or
Near it.It is also, another in the lowering position that the suspension body 26 after reequiping is fallen from the driving rope sheave 23 of new traction machine 21
Side, turn into the suspension body 3 that has set to the counterweight-side suspension body connecting portion 16b set the lifting position identical positions risen or
Person is near it.The diameter of driving rope sheave 23 is more than embodiment 1, to realize such layout.Other structures and repacking side
Method is identical with embodiment 1.
So, by making the lowering position fallen from the driving rope sheave 23 of new traction machine 21 of suspension body 26 and having set outstanding
The lifting position that hanging body 3 rises to suspension body connecting portion 16a, the 16b set is consistent, can make the amount of toppling over of suspension body 26 with changing
It is roughly the same before dress, reduce the influence to layout.
Alternatively, it is also possible to be configured to, the bottom that the cage side suspension body connecting portion 24 after repacking is arranged in hoistway 4,
Suspension body 26 after repacking is also hung on to the car Returning wheel 14 set.
Also, it can also be configured to, the cage side suspension body connecting portion 24 after repacking is arranged on upper support 13
The set location of the counterweight Returning wheel 15 set or its near, the suspension body 26 after repacking is also hung on car Returning wheel 14
The driving rope sheave 7 of the traction machine 5 set.In this case, in the elevator after repacking, the traction machine 5 set does not produce
Driving force, driving rope sheave 7 are used as bottom Returning wheel.Now, by unloading the coiler part of the traction machine set 5 down elimination
Resistance, thus, even if driving rope sheave 7 is used as into bottom Returning wheel, it will not also apply unnecessary load.
In addition, it is the suspension body 3 that will have been set, the traction machine 5 set, car Returning wheel 14 and to returning in the examples described above
Suspension body connecting portion 16a, the 16b for returning wheel 15 and having set are removed, but if without prejudice to the elevator after repacking, then can not also be removed
Retain as former state except these equipment.Thereby, it is possible to cut down discarded object.
In addition, the suspension body 26 after repacking preferably uses new suspension body, but the length of the suspension body 3 set can also be shortened
Spend and the suspension body 26 along after as repacking.
In addition, the suspension body connecting portion 24,25 after repacking preferably uses new suspension body connecting portion, but will can also set
Suspension body connecting portion 16a, 16b along be used as repacking after suspension body connecting portion.
In addition, be that traction machine 21 is set in a manner of making driving rope sheave 23 towards the side of car 1 in the examples described above, but
Can be, in a manner of making driving rope sheave 23 towards 1 opposite side of car, i.e., so that tractor main body 22 towards the side of car 1 side
Formula sets traction machine 21.In this case, the Maintenance and Repair of tractor main body 22 can be easily carried out from car 1.
