Abstract
A modification method of machine room-less (MRL) elevator and a MRL elevator. The invention aims to arrange a traction machine with an installation size and a shape size different from those before modification. During modification of the MRL elevator, a counterweight sheave is unloaded from an upper support (13), and a new traction machine (21) is installed at the position where the counterweight sheave used to be installed. Besides, magnetic force relative to the rotation of a drive sheave is eliminated by unloading a part of a coil from a traction machine (5) at the lower part of a hoistway (4).

Cage side fag end combination (not shown) is provided with near the car guide rail 8a of upper support body 13.1st end of suspension body 3 and cage side fag end are connected.Part between the counterweight diversion sheave 15 and counter weight guide track 9a of upper support body 13 is provided with counterweight-side fag end and combines 16.2nd end and the counterweight-side fag end of suspension body 3 combine 16 and are connected.
Suspension body 3 hangs around the 1st car hanging wheel 11a, the 2nd car hanging wheel 11b, car diversion sheave 14 successively, drives rope sheave 7, counterweight diversion sheave 15 and counterweight hanging wheel 12 from the 1st end side.That is, the elevator of Fig. 1 and Fig. 2 is that wiring is than the elevator for 2:1 mode.
Fig. 3 is the block diagram of the summary that the car diversion sheave 14 of Fig. 2 and the supporting construction of counterweight diversion sheave 15 are shown.Car diversion sheave 14 is configured in the bottom of upper support body 13 near car guide rail 8b.Upper support body 13 has the 1st and the 2nd diversion sheave beam 17a, the 17b configured spaced apart from each other.Diversion sheave beam 17a, 17b are configured in level and parallel with the Width of car 1.Counterweight diversion sheave 15 is configured between diversion sheave beam 17a, 17b.
Then, the method for modifying of the machine-roomless lift both established as above is described.Fig. 4 is the birds-eye view of the summary of state after the repacking of the machine-roomless lift that Fig. 1 is shown, and Fig. 5 is the front view of the summary of the machine-roomless lift that Fig. 4 is shown.In the method for modifying of embodiment 1, unload counterweight diversion sheave 15 from upper support body 13, new towing machine (top towing machine) 21 is set in the position of once installing counterweight diversion sheave 15 of upper support body 13.
Further, the driving rope sheave 7 of the towing machine (bottom towing machine) 5 of hoistway 4 bottom is used as the bottom diversion sheave of the elevator after repacking.In addition, unload lower coil portion from the towing machine 5 of hoistway 4 bottom, eliminate the magnetic resistance relative to the rotation driving rope sheave 7.That is, in the elevator after repacking, towing machine 5 does not produce propulsive effort, only uses as bottom diversion sheave.Further, by the propulsive effort of new towing machine 21, car 1 and counterweight 2 are elevated.
New towing machine 21 is that axial dimension is less than the slim towing machine with the size on axially vertical direction.Further, new towing machine 21 has tractor main body 22 and drives rope sheave 23.Tractor main body 22 has the motor that driving rope sheave 23 is rotated, the drg braked the rotation of driving rope sheave 23.Towing machine 21 is to make the S. A. of driving rope sheave 23 be the level of state and the mode vertical with the Width of car 1 is configured.
Suspension body 3 is hung around from the 1st end side the 1st car hanging wheel 11a, the 2nd car hanging wheel 11b, car diversion sheave 14, the driving rope sheave 23 driving rope sheave (bottom diversion sheave) 7, new towing machine 21 and counterweight hanging wheel 12 successively.That is, the elevator of Fig. 4 and Fig. 5 is also the elevator of 2:1 wiring than mode.
Fig. 6 is the block diagram of the summary of the supporting construction of the towing machine 21 that Fig. 5 is shown.Tractor main body 22 is bearing on the 2nd diversion sheave beam 17b, drives rope sheave 23 to be configured in directly over the space between diversion sheave beam 17a, 17b.Thus, suspension body 3 from driving rope sheave 23 part downward by the space between diversion sheave beam 17a, 17b.Other structure is identical with before repacking, but also can be replaced by new equipment as required.
In the method for modifying of this machine-roomless lift, because the position of counterweight diversion sheave 15 of once configuring on the top in hoistway 4 arranges new towing machine 21, therefore, it is possible to continue to use many equipment to arrange installation dimension and the oad towing machine 21 different from before repacking.Thereby, it is possible to use up-to-date towing machine 21, and realize the shortening of repacking duration.
Further, owing to towing machine 21 can be configured in the top in hoistway 4, therefore pit is just in case water inlet, and towing machine 21 also can not bedew.
In addition, owing to using the driving rope sheave 7 of the towing machine 5 both established as the bottom diversion sheave of the elevator after repacking, even if therefore after the power having cut off towing machine 5, also former state can retain driving rope sheave 7, can waste be cut down.
In addition, owing to eliminating resistance by being unloaded by the coiler part of the towing machine 5 both established, even if rope sheave 7 therefore will be driven to be used as bottom diversion sheave, also unnecessary load can not be applied.
Further, owing to using slim towing machine as new towing machine 21, thus easily towing machine 21 can be set in the space that counterweight diversion sheave 15 is once set.
In addition, on diversion sheave beam 17b, be directly provided with towing machine 21 in figure 6, but also can be, such as shown in Figure 7, between diversion sheave beam 17a, 17b, set up a pair traction board 24a, 24b, traction board 24a, 24b arrange towing machine 21.That is, also across traction board 24a, 24b, towing machine 21 can be arranged on diversion sheave beam 17a, 17b.In this case, the load being applied to towing machine 21 can be made to act on diversion sheave beam 17a, 17b dispersedly, the stress produced in diversion sheave beam 17a, 17b can be made close to before repacking.
Further, in above-mentioned example, towing machine 21 is provided with to make driving rope sheave 23 towards the mode of car 1 side, but also can be, to make driving rope sheave 23 towards the mode of car 1 opposition side, that is, make tractor main body 22 that towing machine 21 is set towards the mode of car 1 side.In this case, the Maintenance and Repair of tractor main body 22 easily can be carried out above car 1.
In addition, in above-mentioned example, counterweight diversion sheave 15 and new towing machine 21 are changed, but also can be, according to be configured in hoistway 4 top equipment layout and car diversion sheave 14 and new towing machine 21 are changed.
In addition also can be the driving rope sheave 7 of the towing machine 5 both established is not used as diversion sheave, removes towing machine 5, new diversion sheave is arranged on the bottom of hoistway 4.
Further, in above-mentioned example, show body elongated towing machine, but also can be as the towing machine 5 both established, the towing machine both established be slim towing machine.
