1 lifting and loopy moving, governor sheave 11 are rotated with speed corresponding with the gait of march of car 1.
Fig. 3 is the front view of the addition attachment device 14 of the Fig. 1 observed along arrow III directions, and Fig. 4 is along arrow
The side view of the addition attachment device 14 for Fig. 3 that IV is observed in direction, Fig. 5 are along the sectional view of the V-V lines in Fig. 3, and Fig. 6 is
Along the sectional view of the line VI -- VI in Fig. 4, Fig. 7 is the exploded view for the addition attachment device 14 for showing Fig. 3, and Fig. 8 is to show Fig. 3
Addition attachment device 14 exploded perspective view.
Additional attachment device 14 has：Additional attachment device frame 15 is installed on the lower part of car 1；Horizontal addition
Extending shaft 16 is held in additional attachment device frame 15 in a rotatable way；Bar connecting component 17 is sling, prolongs addition
Long axis 16 is rotated integrally with slinging bar axis 9；Additional bar 18 is rotated integrally with additional extending shaft 16；And as governor rope
Rope connecting component slings stick 19, and additional bar 18 is connect with overspeed governor 12.
Additional attachment device frame 15 is fixed in car floor 5, and lead to by multiple car floor fixed components 20
It crosses multiple emergent stopping beam fixed components 21 and is fixed in emergent stopping beam 6.As each fixed component 20,21, use respectively
Bolt and nut.
As shown in fig. 7, additional extending shaft 16 has the 1st end 16a and work as the axial end for slinging bar 8a sides
2nd end 16b of the end for the axial side opposite with slinging bar 8a.Also, additional extending shaft 16, which is configured, is slinging bar
On the extended line of axis 9 (be configured to sling bar axis 9 coaxial).In addition, the 1st end 16a cooperations of additional extending shaft 16 are being sling
The end of bar axis 9.
Bar connecting component 17 is sling to connect the 1st end 16a of additional extending shaft 16 with slinging bar axis 9.Also, sling bar
Connecting component 17 has flat bracket part 17a and cylindric hub portion 17b.1st end 16a is inserted into hub portion 17b, and
It is fixed in hub portion 17b.
Bracket part 17a is Chong Die with slinging bar 8a.Also, bracket part 17a is fixed in by slinging bar fixed component 22 and hung
Play bar 8a.As bar fixed component 22 is sling, bolt and nut are used.2nd end 16b of additional bar 18 and additional extending shaft 16
Connection.
In the following, action is illustrated.For example, fracture due to suspension body etc., reaches in the decrease speed of car 1 to limit
During the hypervelocity that fast device 10 is set, the movement of overspeed governor 12 is stopped due to limiter of speed 10.Sling as a result, stick 19 relative to
The car 1 of decline is lifted, and additional bar 18 is rotated centered on adding extending shaft 16.Also, the rotation of additional bar 18 is by chasing after
Add extending shaft 16 and sling bar connecting component 17 and be delivered to and sling bar 8a and sling bar axis 9, emergency braking device 7 acts.
It, will using the addition attachment device 14 with additional extending shaft 16 and additional bar 18 in such lift appliance
It slings bar axis 9 and overspeed governor 12 connects, it is thus possible to sling bar axis 9 when limiter of speed 10 is set to from surface
Be axially away from the position of existing emergency braking device 7.It even that is, cannot be in the existing surface for slinging bar 8a
In the case that limiter of speed 10 is set, it also can easily continue to use existing emergency braking device 7 and new limiter of speed 10 is set.
In addition, bar 8a is sling using slinging bar connecting component 22 and being fixed on bracket part 17a, thus in the additional connection of installation
During device 14, the machining periods such as welding at the scene can be mitigated.
In addition, the inside or outside of bar axis 9 are sling since the 1st end 16a insertions of extending shaft 16 will be added, thus energy
It is enough easily to carry out centering for the existing addition extending shaft 16 sling bar axis 9 and newly set.
In the following, the method for modifying to lift appliance illustrates.For example, it is repacked by the hydraulic elevator of no limiter of speed
In the case of the lift appliance of embodiment 1, additional attachment device frame 15 is fixed on to the lower part of existing car 1.Then,
The addition extending shaft 16 being in a rotatable way held on additional attachment device frame 15 using bar connecting component 17 is sling
The 1st end 16a connect with the bar axis 9 of slinging of existing emergency braking device 7.
Then, additional bar 18 is connect with the 2nd end 16b of additional extending shaft 16.On the other hand, it is set in hoistway 2
Limiter of speed 10 and tensioning wheel 13, and overspeed governor 12 is winded on governor sheave 11 and tensioning wheel 13.Also, it uses
Stick 19 is sling to connect additional bar 18 with overspeed governor 12.
According to this method of modifying, even cannot be in the existing situation for being arranged above limiter of speed 10 for slinging bar 8a
Under, it also can easily continue to use existing emergency braking device 7 and new limiter of speed 10 is set.
In addition, in above-mentioned method of modifying, it can suitably switch the sequence of each process.For example, it is also possible to it first sets
Limiter of speed 10 installs the addition attachment device 14 in a state that factory assembles at the scene.
In addition, in above-mentioned example, show that the hydraulic elevator by no limiter of speed 10 repacks the electricity of embodiment 1 into
The situation of ladder device, but the type of existing lift appliance is without being limited thereto.For example, the present invention also can be suitable for will with Fig. 1
Repack the situation of the lift appliance of embodiment 1 at different positions into there is provided the lift appliance of limiter of speed.
In addition, the lift appliance of side V shape is shown in above-mentioned example, but the present invention can also be led suitable for car
The common type of lift appliance of both sides of the rail configuration in the width direction of car.
In addition, in above-mentioned example, additional extending shaft 16 is directly matched with and slings bar axis 9, but can not also be certain
It is directly connected to.
