Detailed description of the invention
Fig. 1 is existing traction elevator traction-driven system architecture schematic diagram, and Fig. 2 is the utility model traction elevator energy saver schematic diagram.Auxiliary counterweight 19 produces the moment of torsion acted on traction sheave 5 by reel 18, the 4th coupler 17, mechanical gearbox 16, the 3rd coupler 14, slipping toothed electromagnetic clutch 13, second coupler 12 and adapter shaft 6.Auxiliary counterweight 19 moment of torsion acted on traction sheave 5 of advance gear correspondence of mechanical gear box 16 is added in this side of car 10, and auxiliary counterweight 19 moment of torsion acted on traction sheave 5 of reverse gear correspondence is added in balance this side of counterweight 9.Mechanical gearbox 16 changes by the change of gear the moment of torsion that speed ratio that auxiliary counterweight 19 and car 10 move and then change act on traction sheave 5, for mating this side of car 10 and the weight difference balancing this side of counterweight 9, thus it is adjustable to achieve counterweight, and then different load carrying abilities can be mated.Car 10 underloading is up, heavily loaded descending time, utilize the change of auxiliary counterweight 10 position to store the mechanical energy of traction system; When car underloading descending, heavily loaded up time, the potential energy that auxiliary counterweight 10 stores directly discharges.The process of whole energy storage and release does not have the transformation of form of energy.Introduce detailed description of the invention of the present utility model by following four kinds of operating modes now:
Operating mode one: during car 10 no-load run, slipping toothed electromagnetic clutch 13 engages, now mechanical gear box 16 is in reverse gear, and namely the input shaft I of mechanical gear box 16 turns to contrary with output shaft II, makes auxiliary counterweight 19 moment of torsion acted on traction sheave 5 be added to this side of car 10.Load is less, and the weight difference of traction sheave 5 both sides is larger, and mechanical gear box 16 should select the reverse gear that speed ratio is less, and then produces relatively large moment of torsion on traction sheave 5.
Operating mode two: when car 10 heavy service, slipping toothed electromagnetic clutch 13 engages, now mechanical gear box 16 is in D Drive, and namely the input shaft I of mechanical gear box 16 turns to identical with output shaft II, makes auxiliary counterweight 19 moment of torsion acted on traction sheave 5 be added to balance this side of counterweight 10.Load is larger, and the weight difference of traction sheave 5 both sides is larger, and mechanical gear box 16 should select the D Drive that speed ratio is less, and then generation acts on moment of torsion relatively large on traction sheave 5.
Operating mode three: when car 10 runs semi-load, slipping toothed electromagnetic clutch 13 is separated, mechanical gear box 16 is in the most at a high speed than gear, the moment of torsion of such input shaft I is minimum, the braking force needed is also minimum, second brake 15 is in braking mode and makes balance counterweight 19 transfixion, energy saver part is separated with existing elevator traction driving system simultaneously, elevator normally can work by existing traction-driven pattern, this side this amount of stressing of peace weighing apparatus counterweight 9 of car 10 is about the same, and electrical motor 1 needs provide the energy overcoming system friction.
Operating mode four: when auxiliary counterweight 10 is in end position and can not continues the weight difference of this side of compensation balance counterweight 9 and this side of car 10, namely the potential energy that the potential energy that auxiliary counterweight 9 stores reaches maximum capacity or storage all discharges complete, and at this moment the action of each parts is as operating mode three.
Fig. 3 is 16 gear mechanical gear box structural representations.Mechanical gear box 16 adopts electronic control unit (ECU), and gear-shifting actuating mechanism is eight toothpick type magnetic clutchs, and wherein slipping toothed electromagnetic clutch A engages is D Drive, and it is reverse gear that slipping toothed electromagnetic clutch B engages.This mechanical gear box has 16 gears, and comprise eight D Drives and eight reverse gears altogether, drive path is as shown in table 1.
Table 1 mechanical gear box drive path
Mechanical gear box 16 have as much forward gear and to moving back shelves, can and gear arrange more, coupling traction sheave both sides weight difference effect better, energy-saving effect is more obvious; No matter magnetic clutch A or B engages, between input shaft I with the second tween drive shaft IV, there is identical speed ratio, but turn to contrary, just because of the existence of this speed ratio, suitably can increase the weight of auxiliary counterweight 19 according to ele-vator shaft spaces, enable energy saving system of elevator store the potential energy of certain capacity; Are all quiescences when elevator descends passenger on every floor, do not have power resources and Power output during gear shift, each gear and rotating shaft are all static, and the engaging speed of slipping toothed electromagnetic clutch is zero, and gear-change operation is easy.
