The invention described above is based on following groundwork.That is, when resting in the rate of loading of stopping the lift car 2 on layer 6 and for example be 0%, the increase and decrease scope of the load-carrying that produces at next destination floor is to increase at most 100% rate of loading, but rate of loading can not reduce.In addition, when resting in rates of loading in the lift car 2 of stopping on layer 6 and for example being 20%, the increase and decrease scope of the load-carrying that produces at next destination floor is to increase at most 80% rate of loading, and can reduce at most by 20% rate of loading.Moreover when resting in the rate of loading of stopping the lift car 2 on layer 6 and for example being 100%, the increase and decrease scope of the load-carrying that produces at next destination floor is to reduce at most by 100% rate of loading, but rate of loading can not increase.
In addition, the floor 2b of the lift car 2 corresponding with the increase and decrease scope of load-carrying in lift car 2 can calculate according to radical, sectional area and the Young's modulus of hoist cable 4 with the horizontal displacement amount of stopping between layers 6 floor 6a.Therefore, by the increase and decrease scope of judgement in the load-carrying of next destination floor generation, can calculate in advance the horizontal displacement amount that can produce in next destination floor expectation.For example, the range of use of supposing the rate of loading of lift car 2 is 0%～100%, the horizontal displacement of 100mm when becoming 100% from 0%, the rate of loading of lift car 2 has occured, if being positioned at the rate of loading of the lift car 2 of stopping layer 6 is 0%, the horizontal displacement amount that produces at next destination floor is 100mm to the maximum on the descent direction of lift car 2, but can not produce horizontal displacement on ascent direction.If being positioned at the rate of loading of the lift car 2 of stopping layer 6 is 20%, the horizontal displacement amount that produces at next destination floor is 20mm to the maximum on the ascent direction of lift car 2, be 80mm to the maximum on the descent direction of lift car 2.In addition, be 100% if be positioned at the rate of loading of the lift car 2 of stopping layer 6, the horizontal displacement amount that produces at next destination floor is 100mm to the maximum on the ascent direction of lift car 2, but can not produce horizontal displacement on descent direction.
Referring to Fig. 2 to Fig. 5, the correction step of the horizontal displacement of the present embodiment is described.In the present embodiment, adopting shown in Figure 12: 1 hoist cable winding methods, and the rate of loading of lift car 2 is when becoming 100% from 0%, and the elongation of hoist cable is 200mm, and namely to produce the lift facility of the horizontal displacement of 100mm be that example describes to lift car.
According to the present embodiment, as shown in Figure 2, rate of loading be 0% lift car 2 rest in stop layer 6 after, open elevator door, at this moment, as shown in the step S1 of Fig. 5, lift car 2 is in can be for the state of passenger up and down, under this state, the fork truck that goods is housed has entered in lift car 2, makes the rate of loading in lift car 2 for example reach 100% rate of loading, at this moment, hoist cable has extended 200mm, as shown in Figure 3, has occurred the horizontal displacement of 100mm between the floor 6a of the floor 2b of lift car 2 and stop layer 6.Control unit as shown in step S3, utilizes car position adjustment unit 7 that hoist cable 4 is mentioned 200mm to revise this horizontal displacement after step S2 detects this horizontal displacement, becomes state shown in Figure 4 after correction.In addition, as mentioned above, because this elevator has adopted 2: 1 hoist cable winding methods, so, for lift car 2 is mentioned 100mm, need to by car position adjustment unit 7 make slide mass 7a towards the top mobile 200mm.At this moment, slide mass 7a is in the uppermost position of the adjustment stroke that car position adjustment unit 7 has.
After this, in step S4, when having occured to arrive the calling of other floors, as shown in step S5, close the elevator door of lift car 2, after elevator door cut out, control unit utilized load determination unit 12 to measure the load-carrying of lift car 2, and utilized slide mass position detector 11 to detect the position of slide mass 7a.In the present embodiment, the rate of loading that load determination unit 12 is determined as lift car 2 has reached 100% rate of loading, and slide mass position detector 11 detects the uppermost position of the adjustment stroke that has at car position adjustment unit 7 for the position of slide mass 7a.Then, in step S6, control unit judges the increase and decrease scope of the load-carrying that produces at next destination floor, and calculates the horizontal displacement amount that produces because of the load-carrying increase and decrease.Because the current rate of loading of lift car 2 is 100%, so the increase and decrease scope of the load-carrying that produces at next destination floor is that rate of loading reduces 100% at most, but rate of loading can not increase.Therefore, at next destination floor, the horizontal displacement amount of 100mm occurs in lift car 2 in the conference of ascent direction.After this, in step S7, with respect to the load-carrying of lift car 2, control unit judges whether the position of slide mass 7a is positioned at the position that can revise the horizontal displacement that the expectation meeting occurs at next destination floor.In the present embodiment, because the rate of loading of lift car 2 is 100%, and the uppermost position of the adjustment stroke that the position of slide mass 7a has at car position adjustment unit 7 can move down on the position that range is the 200mm stroke so slide mass 7a is currently located at.At this moment, control unit is judged as the position that does not need to adjust slide mass 7a, and enters step S9 and make lift car 2 move to next destination floor.
In addition, in the present embodiment, due to the occasion take the rate of loading that is positioned at the lift car 2 of stopping layer 6 as 100% as example, adjust so be judged as the position that does not need slide mass 7a in step S7, this judgement is that the position according to the load-carrying of current lift car 2 and slide mass 7a judges.When the rate of loading that is positioned at the lift car of stopping layer 6 for example is 0%, according to the position of slide mass 7a, in step S8, slide mass 7a is moved to the position of mobile 200mm up in advance.In addition, when the rate of loading that is positioned at the lift car 2 of stopping layer 6 for example is 20%, according to the position of slide mass 7a, in step S8, slide mass 7a is moved to mobile 160mm up in advance, and the position of mobile 40mm down.
So, the car position adjustment unit 7 shown in the present embodiment only need to guarantee that the adjustment stroke of 200mm gets final product altogether at above-below direction.On the other hand, when adopting existing car position adjustment unit in the elevator of the same terms, as mentioned above, need to guarantee altogether the adjustment stroke of 400mm at above-below direction.Therefore, the adjustment stroke of the car position adjustment unit 7 shown in the present embodiment be existing car position adjustment unit the adjustment stroke 1/2nd.
In the present embodiment, can obtain to adjust the short car position adjustment unit of stroke, therefore can realize the miniaturization of lift facility, and can reduce costs.
In addition, show in the present embodiment the example that hydraulic efficiency pressure system 7b only is set in the side of slide mass 7a, but also can in the both sides of slide mass 7a, hydraulic jack be set according to the specification of elevator, to obtain larger propulsive effort.In addition, adopted in the present embodiment the hydraulic efficiency pressure system 7b that drives along the vertical direction slide mass 7a, but the present invention is not only for this, as long as can make slide mass 7a stably mobile along the vertical direction with the speed of regulation.In addition, in the present embodiment, in order to detect the position of slide mass 7a, be provided with the slide mass position detector 11 with swivel 11b, as long as but can detect which position of position in the adjustment stroke that the car position adjustment unit has of slide mass 7a.
