Detailed description of the invention
It should be noted that in the case of not conflicting, the embodiment in this utility model and the feature in embodiment can
To be mutually combined.Describe this utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
Basic thought of the present utility model is: by two reels and two lifting devices, connects two loadings respectively,
All offset with the gravity of one of them loading or the gravity of another loading of partial offset, reach mutually to balance, to realize joint
Consumable effect.Below in conjunction with the accompanying drawings, preferred embodiment of the present utility model is described in further detail:
As shown in Figure 1, it is shown that a specific embodiment of this utility model energy conserving system, including stay cord 100, first
Reel the 200, second reel the 300, first lifting device 400 and the second lifting device 500.Wherein, the top of stay cord 100 is fixed,
And successively after first reel the 200, first lifting device the 400, second reel 300 and the second lifting device 500, end is fixed.
In this embodiment, give a preferred embodiment of energy conserving system, the first reel 200 and volume Two can be passed through
The relative velocity of cylinder 300, control the loading A on the first lifting device 400 and the loading B on the second lifting device 500 lifting or
Landing, the gravitional force so that loading A, B can cancel out each other, keep balancing each other mutually, it is not necessary to extra balancing weight, reach energy-conservation
The effect of consumption reduction.Example, when the first lifting device 400 declines loading A, the second lifting device 500 can be controlled and promote loading
B, to store the gravitional force discharged when loading A declines, when the second lifting device 400 needs promote loading A again or need
When promoting other loading, the second lifting device 500 can be controlled and decline loading B, discharge the gravitional force of its storage, reach joint
The effect that can lower consumption.
Concrete, under the conditions of this structure of tow line, the direction of motion of the loading A on the first lifting device 400 and motion speed
Spend and determined by the superposition of the first reel 200 and the speed of the second reel 300, the motion side of the loading B on the second lifting device 500
Determine by the speed of the second reel 300 to movement velocity.More specifically, following is a brief introduction of this utility model energy conserving system
Several common operating mode:
Operating mode 1: the second reel 300 turns clockwise as shown in Figure 2, and loading A rises, and loading B declines, now under loading B
The gravitional force that fall is discharged is converted to the energy that loading A rises, and reaches energy-saving and cost-reducing effect.
Operating mode 2: the second reel 300 rotates counterclockwise as shown in Figure 3, and loading A declines, and loading B rises, now under loading A
The gravitional force that fall is discharged is converted to the energy that loading B rises, and reaches energy conservation and consumption reduction effects.
Operating mode 3: the first reel 200 and the second reel 300 all turn clockwise as shown in Figure 4, cause loading A and loading B
All declining, now the speed of loading A is the first reel 200 and speed of the second reel 300 superposition, and the speed of loading B is second
The speed of reel 300, reaches energy conservation and consumption reduction effects.
Operating mode 4: the first reel 200 and the second reel 300 rotate the most counterclockwise as shown in Figure 5, cause loading A and loading B
All promoting, now the speed of loading A is the first reel 200 and speed of the second reel 300 superposition, and the speed of loading B is second
The speed of reel 300, reaches energy conservation and consumption reduction effects.
It is noted that 1-4 disclosed above is only the concrete example of explanation, operator according to promoting, can decline demand
And speed, Self-operating the first reel 200 and the second reel 300.
Preferably, as shown in Figure 6, energy conserving system of the present utility model, also include angle pulley, be arranged on stay cord 100
Corner.Concrete, the quantity of this angle pulley 600 and position, can be by designer according to first reel the 200, second reel
300, the first lifting device 400 and position of the second lifting device 500, and consider the corner needed for stay cord 100, and at each
Corner arranges one or more angle pulley 600, and makes steel wire rope strain, not fall out further.Example, such as Fig. 6
Shown in, the top of stay cord 100 is fixed, and after being wound around the first reel 200 after two angle pulleies 600 turn to, is wound around the first lifting
Device 400, then after two angle pulleies 600 turn to, after being wound around the second reel 300, then it is wound around through seven angle pulleies 600
Two lifting devices 500.Preferably, this angle pulley 600, optional but be not limited only to as fixed pulley.
In this embodiment, angle pulley 600 is set in the required corner of stay cord 100, can simple and efficient change draw
The direction of rope 100, it is to avoid it loosens and drops, and there is potential safety hazard.
It is more highly preferred to, as shown in Figure 6, energy conserving system of the present utility model, also include the pulley 700 that converts, be wound around and arrange
Or/and the second reel 300 and the second lifting device on stay cord 100 between the first reel 200 and the first lifting device 400
On stay cord 100 between 500.Concrete, designer can be according to loading A and the proportionate relationship of the weight of loading B, first
Or/and between the second reel 300 and the second lifting device 500 on stay cord 100 between reel 200 and the first lifting device 400
Stay cord 100 on be wound around some conversion pulleys 700, to change stay cord 100 at the first lifting device 400 and the second lifting device
The multiplying power relation of 500 positions, conversion is offset the weight differential between loading A and loading B, is played and balance each other mutually or labour-saving work
With.Example, as shown in Figure 6, stay cord 100, when being connected with the second lifting device 500, increases one group of conversion pulley 700 newly, so that
Multiplying power relation at first lifting device 400 and the second lifting device 500 is 2:1, the loading A that the first lifting device 400 promotes
When running the distance of L rice up and down, the loading B that the second lifting device 500 promotes runs L/2 rice the most up and down, the gravitational potential of its conversion
Can also convert in proportion accordingly, to balance the weight relationships that between loading A and loading B, itself exists.It is more highly preferred to, loading A
With the proportionate relationship of the weight at loading B, can not cancel out each other, and according to actual condition and requirement, be changed by conversion pulley 700
Zoom rate relation, and it is designed as certain proportionate relationship.Being more highly preferred to, convert pulley 700, optional but be not limited only to as determining cunning
Wheel.
