The specific embodiment
With reference to the accompanying drawings preferred implementation of the present invention is described.
Embodiment one
Fig. 1 is the front elevation of the lift appliance of expression embodiment of the present invention one.In addition, Fig. 2 is the lateral plan of the lift appliance in the presentation graphs 1.In the drawings, in hoistway 1, liftably dispose car 2 as lifting body.In addition, in hoistway 1, be provided with a pair of car guide rail (not shown) that is used to guide car 2.Car 2 is guiding lifting in hoistway 1 by each car guide rail.
Centre portion at a side surface part 2e is provided with to the outstanding protrusion 4 in the outside of car 2, and protrusion 4 extends from car 2 along continuous straight runs.Protrusion 4 is disposed at outside the zone of car 2 in the vertical plane of hoistway 1.
Top in hoistway 1 is provided with actuating device (towing machine) 5, and this actuating device 5 produces the propulsive effort that is used to make car 2 liftings.Actuating device 5 comprises: have the actuating device main body 6 of electrical motor and the driving rope sheave 7 that rotates by actuating device main body 6.Actuating device 5 is the radial dimension little slim towing machine of axial dimension than actuating device main body 6 or driving rope sheave 7.In addition, actuating device 5 is configured to make it axially to be the Width of hoistway 1.
Volume hangs with many main ropes 8 on the rope sheave 7 driving.Car 2 is suspended in the hoistway 1 by each main rope 8.Peripheral part at each main rope 8 is coated with high friction material.Thereby, can guarantee to drive the friction force between rope sheave 7 and each the main rope 8.
Bottom in hoistway 1 is provided with the tension wheel 9 that volume has been hung each main rope 8.Tension wheel 9 can be shifted with respect to car guide rail.In this example, tension wheel 9 is installed on the rotatable parts that can rotate with respect to car guide rail on above-below direction.And tension wheel 9 is by each main rope 8 suspention.Thus, 9 pairs of each main ropes 8 of tension wheel apply tension force.In addition, on tension wheel 9, be provided with and be used for the tension force that puts on each main rope 8 is guaranteed weight (not shown) for pre-sizing.
Be provided with on the protrusion 4: be used for above protrusion 4, each main rope 8 being connected in the upside lanyard portion 10 of protrusion 4, and the underside strand fixed part 11 that is used for below protrusion 4, each main rope 8 being connected in protrusion 4.Each main rope 8 comprises: with upside lanyard portion 10 bonded assemblys, first connecting portion (end) 8a, and with underside strand fixed part 11 bonded assemblys, second connecting portions (the other end) 8b.Each main rope 8 is rolled up successively to be hung on from first connecting portion 8a to the second connecting portion 8b and is driven rope sheave 7 and tension wheel 9.That is, the lift appliance of embodiment one is the elevator without counterweight device that counterweight is not set.
Actuating device 5 and tension wheel 9 are disposed at outside the zone of car 2 in the vertical plane of hoistway 1.Car 2 can lifting between upper limit position and lower position, and wherein, above-mentioned upper limit position is the position that the position of smallpox board 2b is higher than the position of actuating device 5, and above-mentioned lower position is the position that the position of base plate 2a is lower than the position of tension wheel 9.
In addition, be used for the suspension craning cab 2 and lifting mechanism 12 of its lifting in hoistway 1 is comprised: actuating device 5, main rope 8 and tension wheel 9.Lifting mechanism 12 is disposed at outside the zone of car 2 in the vertical plane of hoistway 1.
Below action is described.When actuating device 5 is driven, drive rope sheave 7 rotations.Thus, each main rope 8 circulates mobile, makes car 2 lifting in hoistway 1.At this moment, car 2 is stably guided by car guide rail.
In this lift appliance, owing on car 2, be provided with outstanding protrusion 4 from the side surface part 2e of car 2, therefore and the first connecting portion 8a of each main rope 8 is connected with protrusion 4 with the second connecting portion 8b, can make to be used for position limit with each main rope 8 and car 2 bonded assembly upside lanyard portions 10 and underside strand fixed part 11 in the height dimension scope of car 2.Therefore, can make the space of the above and below of car 2 dwindle the part of the height dimension that is equivalent to lanyard portion 10,11, thereby can reduce the size of hoistway 1 on short transverse.
In addition, because lifting mechanism 12 is disposed at outside the zone of car 2 in the vertical plane of hoistway 1, therefore when car 2 in hoistway 1 during lifting, even when the part arrival of car 2 is provided with the height of the either party in actuating device 5 and the tension wheel 9, actuating device 5 and tension wheel 9 also can not produce with car 2 interferes.Therefore, in hoistway 1, can enlarge the liftable scope of car 2, the size of hoistway 1 on short transverse further reduced.
