Description
[technical field]
The present invention relates to a kind of elevator, in particular the vertical lift traction elevator.
[background technology]
The every ladder of vertical lift traction elevator has one or two car and a counterweight at present, each car all disposes a traction motor, utilize hoist ropes to couple together between traction motor and the car afterwards, the frictional force drives car that traction motor utilizes hoist ropes and traction sheave up or walk downward.Wherein the weight of counterweight be the car own wt add the elevator payload ratings 40 to 50 percent, when having only being equal in weight of traction sheave two ends, the power consumption of towing machine is just minimum.For the occasion of team control or the single control of many ladders, the various energy saving technologys of elevator of structure are widely used at present, mainly are the application that energy-conservation towing machine, energy-conserving control technology, energy regeneration is utilized technology etc.
[summary of the invention]
The present invention has overcome the deficiencies in the prior art, and the energy-saving double-car elevator that energy savings, cost are low, drag the practicality of car on two with a traction motor is provided.
In order to solve the technical matters of above-mentioned existence, the present invention adopts following technical proposal:
Energy-saving double-car elevator, include drag device, be respectively equipped with in the both sides of drag device and drive the upper and lower first mobile car and second car by it, also be provided with in addition and be used for the counterweight of balance second car weight, between each device, be serially connected with the hoist ropes of finishing its continuous action relation, one end of hoist ropes is fixed on the girder steel, and the other end is walked around the diversion sheave of first car, the traction sheave of drag device and the diversion sheave of second car respectively successively, is fixed on the counterweight at last.
Aforesaid energy-saving double-car elevator also is provided with the leveling device that is used for regulating the second car flat bed between second car and counterweight, described hoist ropes come out to walk around from the diversion sheave of second car behind the traction sheave of leveling device with to reconnecting.
Aforesaid energy-saving double-car elevator, being equal in weight of described first car and second car.
The present invention compared with prior art has following advantage:
1, since the present invention only with a drag device drive two cars about, utilize two elevators of cover system control, saved one and overlapped control system, cost greatly reduces;
2, two elevators whole and, make it can reduce by a cover counterweight (comprising counterweight frame, counterweight side rails, support, energy disperser and pit parts), and counterweight of the present invention is 50% of a present counterweight, has saved a large amount of steel, is equivalent to the steel of a ladder about 90%;
3, the present invention adopts a drag device as driving, a leveling device is regulated as flat bed and is used, then the requirement of the towing machine in the leveling device can reduce, elevator as 2.0m/s, flat bed towing machine speed only needs about 0.5m/s, the flat bed towing machine does not need work when leveling accuracy, and the flat bed towing machine life-span increases greatly like this;
4, great advantage of the present invention is to save the energy:
A. at first owing to lacked a cover drag device, just saved the traction motor in the drag device, this has just saved nearly 50% electric energy, and the towing machine in another leveling device just need not be worked in the time need not regulating flat bed;
B. when the car no-load run, because two car weights are identical, the traction motor acting in the drag device is very little;
C. when car had load-carrying, it was equal to consider that the load-carrying both sides are close to, and drove the relative conventional elevator acting of traction motor and reduced greatly, and when conventional elevator had only being equal in weight of traction sheave two ends, the towing machine acting was just minimum.

Fig. 4 is the scheme drawing of prior art.
[specific embodiment]
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail:
Energy-saving double-car elevator, as shown in Figure 1, include drag device 1, be respectively equipped with in the both sides of drag device 1 and drive by it, mobile down first car 2 and second car 3, being equal in weight of described first car 2 and second car 3, also be provided with in addition and be used for the counterweight 5 of balance second car 3 weight, between each device, be serially connected with the hoist ropes 6 of finishing its continuous action relation, one end of hoist ropes 6 is fixed on the girder steel, the other end is walked around the diversion sheave of first car 2 respectively successively, the diversion sheave of the traction sheave of drag device 1 and second car 3 is fixed on the counterweight (5) at last.
Between second car 3 and counterweight 5, also be provided with the leveling device 4 that is used for regulating flat bed, described hoist ropes 6 is connected with counterweight 5 come out to walk around the traction sheave of leveling device 4 from the diversion sheave of second car 3 after, that is to say that at first hoist ropes 6 is fixed on the girder steel, the other end passes the traction sheave of upwards walking around drag device 1 behind the diversion sheave of first car 2 again, the hoist ropes 6 that comes out from the traction sheave of drag device 1 is passed down through the traction sheave of upwards walking around leveling device 4 behind the diversion sheave of second car 3, hoist ropes 6 terminal counterweights 5 that connect that come out from the traction sheave of leveling device 4 afterwards, each device just couples together by hoist ropes 6 like this, form interactive relationship, drag hoist ropes 6 by drag device 1, when first car 2 was up moved, second car 3 moved downward accordingly; When first car 2 is come the floor of setting, and second car 3 is not when also coming the floor of setting, and the traction motor of leveling device 4 will be worked, and drags hoist ropes 6 and makes second car 3 arrive the position of setting.
As shown in Figure 3, described drag device 1 includes main frame traction sheave 9, the circumferential surface of described main frame traction sheave 9 is provided with many row's traction grooves 7, described steel rope 6 is wrapped in 7 li of traction grooves, described traction groove 7 includes friction part 8 and places the bottom 9 of friction part 8, and described steel rope 6 contacts with friction part 8.
Give an example: as shown in Figure 2, the building of one ten stop, interlamellar spacing 3m.Elevator basic specification: payload ratings 1000kg, 1.75m/s, the driving traction motor command speed 1.75m/s in the drag device 1, the flat bed traction motor command speed 0.5m/s in the leveling device 4.Set first car 2 and stop floor in the 10,9,7,5,3,1st building, corresponding second car 3 stops layer 1,2,4,6,8,10, so just can maximally utilise elevator, save the energy, raise the efficiency, the present invention relatively is applicable to upstairs and the much the same situation of number of going downstairs, such two cars can be fully utilized, and the number of two cars is similar, and weight is also similar, the worker that the driving traction motor is done is fewer, energy-conservation.And for the occasion of how terraced team control, if any 4 elevators, wherein 2 elevators are this programme pattern, in addition two be the conventional lift pattern, when the number of going upstairs many, promptly during up peak, conventional lift is carried out up unidirectional operation, and the elevator of this programme is carried out two-way collection selected control system, promptly carries out way traffic; When downstairs number is many, during lowering peak, conventional lift is carried out descending unidirectional operation, and this programme ladder is carried out two-way collection selected control system, promptly carries out way traffic; All similar when the number in upper and lower building, promptly during balance movement, this programme elevator is carried out preferential operation, and energy savings so greatly improves the overall operation efficiency of elevator.
