Description
Technical field
The present invention relates to a kind of elevator.
Background technology
Elevator is a kind of vertical conveyor with motor as power, equipped with box like gondola, takes advantage of people or load for tier building
Cargo transport thing.Vertical lift elevator has a car, operates at least two rigid guideways that row are vertical or inclination angle is less than 15 °
Between.Car size and version are easy to passenger and are come in and gone out or handling goods.Existing elevator pass through traction motor, traction sheave,
Traction steel-cable realizes the lifting of car, and due to employing frictional wheel drive draw mode, the lifting greatly increasing elevator is high
Degree.And traction from frictional force, the size of frictional force depends on coefficient of friction and pressure.The fixing situation of coefficient of friction
Under, pressure is bigger, and the frictional force of generation is bigger, and traction capacity is stronger.And bigger pressure is provided and is carried on electricity it is necessary to increase
Weight on machine, that rotates to motor needs higher moment of torsion, and that is accomplished by more electric energy, later in the other side of car
Setting can offset the device counterweight of car deadweight and certain load-carrying, it is possible to achieve the target of energy-conservation.The optimal shape that elevator runs
State is that the deadweight of car is exactly equal to the weight of counterweight plus load-carrying.So (be equivalent to and determining of power can be provided in traction sheave
Pulley) both sides power equal.And it is applied to the power maximum on wheel, traction capacity is the strongest, and energy consumption only needs to overcome inertia force.
Problem is the load-carrying of elevator is change, and the quality of counterweight is changeless, as holding of traction sheave both sides steel wire rope
Loading capacity, will result in the increase of energy consumption of electrical machinery, and it is bigger more to tend to energy consumption that is unloaded or more tending to full elevator.
Content of the invention
The purpose of the present invention is for deficiencies of the prior art, provides a kind of counterweight balance elevator, it can be real
Whenever now the load capacity of traction sheave both sides steel wire rope is equal, thus realizing energy-conservation.
For reaching above-mentioned purpose, the counterweight balance elevator of the present invention, including traction motor, traction sheave, tensioning wheel, middle part around
Traction steel-cable on traction sheave and tensioning wheel, one end of traction steel-cable is coupled with car upper end, on the other end and counterweight
It is characterised in that being provided with more than one rope sheave below car and counterweight, one compensates one end and the car lower end of rope for end connection
Connection, the middle part compensating rope is around on all rope sheaves, and the other end compensating rope is coupled with counterweight lower end, is all provided with the both sides of rope sheave
Have guide rail, each guide rail all slide located at more than one compensation counterweight, each compensate counterweight all by respective electromagnetism from
Clutch is connected with compensating rope, is provided with pressure transducer in car inner bottom part, pressure transducer and all electromagnetic clutchs all with can
Programmable controller is connected.
During work, traction sheave is driven by traction motor；Increased compensation rope makes it and traction steel-cable, car, counterweight
Form loop configuration, no matter car lifts, the car of traction sheave side adds steel wire rope and compensation rope and adds steel with the counterweight of opposite side
The weight of cord and compensation rope can keep constant, and when the load-carrying in car changes, this signal is fed back by pressure transducer
To Programmable Logic Controller, the electromagnetic clutch that Programmable Logic Controller presses the side of operating conditions rope sheave closes with compensating knot, corresponding
Compensation counterweight with compensate rope one lifting so that whenever the load capacity of traction sheave both sides steel wire rope equal, thus real
Existing energy-conservation；
As a further improvement on the present invention, described traction sheave is provided with connected straight trough and V-shaped groove, and straight trough is located at V-shaped groove
Inner side, the diameter of traction steel-cable is slightly larger than straight trough width；Traction steel-cable is stuck in straight trough and the junction of V-shaped groove, can increase
Traction sheave and the frictional force of steel wire rope, are unlikely to steel wire rope and skid on the traction sheave, safety is good；
In sum, the present invention enable whenever traction sheave both sides steel wire rope load capacity equal, thus realizing
Energy-conservation, safety is good.
Brief description
Fig. 1 is the front view of the embodiment of the present invention.
Fig. 2 is the front view of traction sheave.
Specific embodiment
The present invention is further detailed explanation below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, this counterweight balance elevator, including traction motor (not shown), traction sheave 1, tensioning wheel 2, in
Portion is around in the traction steel-cable 3 on traction sheave 1 and tensioning wheel 2, and described traction sheave 1 is provided with connected straight trough 4 and V-shaped groove 5, directly
Groove 4 is located inside V-shaped groove 5, and the diameter of traction steel-cable 3 is slightly larger than the width of straight trough 4, one end of traction steel-cable 3 and car 6
Upper end couples, and the other end is coupled with counterweight 7 upper end, is provided with two rope sheaves 8 below car 6 and counterweight 7, and one compensates the one of rope 9
End is coupled with car 6 lower end, and the middle part compensating rope 9 is around on two rope sheaves 8, and the other end compensating rope 9 is coupled with counterweight 7 lower end,
It is equipped with guide rail 10 in the both sides of two rope sheaves 8, each guide rail 10 all slides located at several compensation counterweights 11, each compensates counterweight
11 are all connected with compensating rope 9 by respective electromagnetic clutch 12, are provided with pressure transducer 13 in car 6 inner bottom part, pressure passes
Sensor 13 and all electromagnetic clutchs 12 are all connected with Programmable Logic Controller (plc, not shown).
During work, traction sheave 1 is driven by traction motor, and in elevator runs, car 6 and counterweight 7 are reverse direction operations,
When the position in top layer for the car 6, counterweight 7 will be in bottom；In bottom, counterweight 7 then runs to top layer to car 6；Increased benefit
Repay that rope 9 makes it with traction steel-cable 3, car 6, counterweight 7 form loop configuration, compensate rope 9 and be also adopted by steel wire rope, no matter car
6 liftings, the car 6 of traction sheave 1 side plus traction steel-cable 3 and compensate the counterweight 7 of rope 9 and opposite side plus traction steel-cable 3 and
The weight compensating rope 9 can keep constant, and when the load-carrying in car 6 changes, this signal is fed back to by pressure transducer 13
Programmable Logic Controller, such as now the weight of car 6 side is more than the weight of counterweight 7 side, then Controlled by Programmable Controller counterweight 7
The electromagnetic clutch 12 of side with compensate rope and 9 be combined, the compensation counterweight 11 of this side with compensating rope 9 one liftings, such as now car 6
The weight of side is less than the weight of counterweight 7 side, then the electromagnetic clutch 12 of Controlled by Programmable Controller car 6 side and compensation
Rope 9 combination, the compensation counterweight 11 of this side is with compensating rope 9 one liftings so that whenever traction sheave 1 both sides traction steel-cable 3
Load capacity equal, thus realizing energy-conservation；Traction steel-cable 3 is stuck in straight trough 4 and the junction of V-shaped groove 5, can increase traction sheave
1 with the frictional force of traction steel-cable 3, it is to avoid skid, safety is good.
