Lifted with to focusing in hoistway.
Deflector sheave is provided with ground 2 and replaces accessory 21.Deflector sheave replaces accessory 21 and is replacing deflector sheave assembly 10
When be arranged on ground 2, removed in the usual operating of elevator from ground 2.
In addition, deflector sheave, which replaces accessory 21, has a pair of tracks 22a, 22b as guide member, mobile trolley used 23, more
A supporting station 24, multiple jack the 25, the 1st and the 2nd radial positioning component 26a, 26b.
Track 22a, 22b are arranged on the lower section in the space between engine base 4a, 4b and are arranged on ground 2.In addition,
Track 22a, 22b are along the length direction of engine base 4a, 4b by parallel and flatly set.Mobile trolley used 23 can along track 22a,
22b is moved as between the lower space in the space of the lower section of traction machine 5 and the outside of the lower space.In mobile station
The multiple wheel 23a rolled along track 22a, 22b are provided with car 23.
Each supporting station 24 is mounted on mobile trolley used 23 by jack 25.Each supporting station 24 can utilize jack 25
Moved up and down.That is, the height of supporting station 24 can be adjusted by jack 25.
1st and the 2nd radial positioning component 26a, 26b is configured to be spaced apart interval in the axial direction of local derviation wheel shaft 11.
In addition, the state that outer circumferential surfaces of the 1st and the 2nd radial positioning component 26a, the 26b at the axial both ends with local derviation wheel shaft 11 contacts
Under be installed on ground 2 or engine base 4a, 4b etc. on.Such as using center bridge etc. as the 1st and the 2nd radial positioning component 26a,
26b。
Then, the deflector sheave replacing options of embodiment 1 are illustrated.What is replaced to deflector sheave assembly 10
In the case of, first, as preparation work, set deflector sheave to replace accessory 21 on ground 2.At this time, radial positioning portion is made in advance
Part 26a, 26b are contacted with local derviation wheel shaft 11.In addition, in the state of supporting station 24 is laid down, mobile trolley used 23 in lower space
It is outer to set onto track 22a, 22b.
Afterwards, mobile trolley used 23 are made to be moved along the lower section of track 22a, 22b to original deflector sheave assembly 10.Connect down
Come, supporting station 24 is increased, and as depicted in figs. 1 and 2, become and accepted deflector sheave assembly 10 and deflector sheave beam 9a, 9b
State, and original deflector sheave assembly 10 is disconnected with traction machine 5 according to each local derviation wheel apparatus 8.
Then, as shown in Figure 3 and Figure 4, decline supporting station 24, local derviation wheel apparatus 8 is separated from traction machine 5.Then, make
Mobile trolley used 23 move along the space that can carry out replacement operation of track 22a, 22b to outside lower space.At this time, mobile station
Car 23 is moved between engine base 4a, 4b along engine base 4a, 4b.Fig. 5, which is shown, makes mobile trolley used 23 along track 22a, 22b
The state of mobile midway.
Afterwards, local derviation wheel apparatus 8 is unloaded from mobile trolley used 23, and original deflector sheave is pulled down from deflector sheave beam 9a, 9b
Assembly 10.Then, new deflector sheave assembly is installed on deflector sheave beam 9a, 9b.That is, by original deflector sheave assembly
10 are changed to new deflector sheave assembly.New deflector sheave assembly is assembled correctly in the factory.
Then, the local derviation wheel apparatus after replacement operation will have been carried out to be carried on mobile trolley used 23, and made mobile trolley used
23 move along the lower section of track 22a, 22b to traction machine 5.At this time, the local derviation wheel shaft and radial direction of new deflector sheave assembly are made
Positioning element 26a, 26b are contacted and are carried out the positioning of new deflector sheave assembly, and supporting station 24 is increased.Then, will be inclined
Guide wheel beam 9a, 9b are fixed on traction machine 5, and new deflector sheave assembly is suspended in midair from the lower part of traction machine 5.
Such elevator deflector sheave replacing options and deflector sheave replace accessory 21 in, by with original deflector sheave group
The local derviation wheel shaft 11 of dress body 10 contacts, and carries out the positioning of the 1st and the 2nd radial positioning component 26a, 26b, and makes new deflector sheave
The local derviation wheel shaft of assembly is contacted with the 1st and the 2nd radial positioning component 26a, 26b so as to carry out determining for new deflector sheave assembly
Position, therefore centering operation need not be especially carried out, the position of deflector sheave 12 just can accurately be reverted to the position before replacing.
In addition, deflector sheave 12 can be carried out upper by the way that deflector sheave beam 9a, 9b are fixed on the lower surface of traction machine 5
The upward positioning in lower section.Also, set by making mobile trolley used 23 along on the basis of the 1st and the 2nd radial positioning component 26a, 26b
Track 22a, 22b movement put, additionally it is possible to easily make the position pair in the axial direction of the local derviation wheel shaft of new deflector sheave assembly
It is accurate.
In the state of being arranged on always on engine base 4a, 4b in traction machine 5, carry out deflector sheave 12 replacement and
Centering, so as to reduce the trouble of the replacement operation of deflector sheave assembly 10.
Further, since having used the 1st and the 2nd radial positioning component 26a, 26b, therefore it can also prevent local derviation wheel shaft 11
The swing of center line.
Also, by accurately setting new deflector sheave, additionally it is possible to accurately recover the suspension body of suspension craning cab
Path.
Furthermore due to being provided with rail in a manner of making mobile trolley used 23 to be moved between engine base 4a, 4b along engine base 4a, 4b
Road 22a, 22b, therefore the replacement operation of deflector sheave assembly 10 can efficiently be carried out with less amount of movement.
Further, since moving up and down supporting station 24 by jack 25, therefore can be made by simple structure
Deflector sheave assembly 10 moves up and down.
Embodiment 2.
Then, the side view of state when Fig. 6 is the use for the deflector sheave replacement accessory for showing embodiments of the present invention 2
Figure.The deflector sheave of embodiment 2 replaces accessory in addition to the structure of embodiment 1, and also having makes mobile trolley used 23 along rail
The driving device 27 of road 22a, 22b movement and by driving device 27 and mobile trolley used 23 drive transfer parts 28 linked.
