Detailed description of the invention

Referring to the drawings one embodiment of the present invention is described in detail.

Fig. 1 represents the overall structure of the lift facility 100 in present embodiment.Lift facility 100 is constructed having and sets Put the liftway 1 in building, the Machine Room 2 being formed at this liftway 1 top, the volume that is arranged in this Machine Room 2 Raise machine 3, be arranged on Machine Room 2 in and be driven hoist engine 3 controlling control dish 4, be wound on the rope sheave 3a of hoist engine 3 Main hoist cable 5 be connected with one end of this main hoist cable 5 and in liftway 1 lift car 6 and this main hoist cable 5 of lifting another One end connect and the balance weight 7 that lifts in liftway 1 along the direction contrary with lift car 6 and with main hoist cable The compensation rope 8 that contrary side is connected with lift car 6 and balance weight 7.

The normal speed that lift facility 100 is set to when lift car 6 rises is faster than normal speed when declining.By electricity Translational speed when ladder car 6 rises is set higher than the reason of translational speed when declining, according to the characteristic of the ear of people, When air pressure declines, (when lift car 6 rises) rises with air pressure compared with (when lift car 6 declines), the ear of passenger more can Adapt to the air pressure change drastically caused because lift car 6 lifts, say, that when dropping under pneumatic pressure, (lift car 6 rises Time) ear of passenger is than less easily causing tinnitus and earplug sense.

Fig. 2 represents the Facad structure of the balance weight 7 when being fitted without cover body.Additionally, the Facad structure of the balance weight 7 of Fig. 2 It it is the Facad structure observed when arrow A observes the balance weight 7 of Fig. 1.

Balance weight 7 has: balance weight framework 70, its by be arranged oppositely mutually a pair longitudinal framework 70A, connect these longitudinally Top framework 70B on framework 70A top and connect bottom framework 70C of these longitudinal framework 70A bottoms and constitute；It is positioned in this Multiple weights 71 in balance weight framework 70；And guiding elements 72, this guiding elements 72 is arranged on the upper end of longitudinal framework 70A And lower end, along not shown balance weight slide.Compensating rope 8 and be arranged on the lower section of balance weight 7, its end is fixed on On beam 73, beam 73 is erected between longitudinal framework 70A.

In balance weight 7 in the present embodiment, setting than being provided with the central part of intermediate beam 76 position more on the lower Be equipped with peristome 74, as in figure 2 it is shown, this peristome 74 from front (lift car side) towards the back side (opposition side of lift car) Run through balance weight 7.

Fig. 3 represents the Facad structure of the balance weight 7 when being mounted with cover body.The purpose that arranges of cover body 75 is to cover balance Weight framework 70 and weight 71, be made up of top cover body 75A, longitudinal cover body 75B and bottom cover body 75C, and top cover body 75A is at electricity Ladder cage side (front) covers from top framework 70B position to intermediate beam 76, and longitudinal cover body 75B covers peristome 74 Both sides, bottom cover body 75C covers the position from the lower end of bottom framework 70C to the lower end of longitudinal cover body 75B.Additionally, it is electric The structure of the cover body 75 of the opposition side (back side) of ladder car is identical with the structure in front.
