Description

Gravity elevator

The novel lifting technical field of transportation means that relates to of this usefulness.

Aspect prior art, lifting machinery such as elevator are to be power with the electric energy, therefore consume a large amount of electric power.

The purpose of this utility model is: providing a kind of is the lifting tool of whole or main energy sources with gravitional force, replaces lifting machinery such as elevator, a large amount of saving in power electric energy.

We know that in gravitational field, object overcomes gravity and rises certain elevation H to the work done of B point from the displacement of A point under external force F effect, and the energy of consumption equals this object and obtained the gravitional force that return A is ordered.The utility model is according to above-mentioned principle design.

Be the utilizability matter of explanation gravitional force, proved below in conjunction with Fig. 1:

M among the figure _AFor by carrying object, m _BBe and m _AEquiponderant accumulation of energy counterweight.m _AWith m _BBetween connect with two isometric ropes respectively and hang on two pulleys.m _AWith m _BBetween diff-H h is arranged.At this moment, m _AThe A point there is potential energy V _h=m _AGh, apply the power that overcomes friction, m by anticlockwise direction as giving pulley 1 _AJust can fall the A plane after rise and discharge potential energy V _h, simultaneously with m _BDraw high the B plane and make m _BPromptly stored potential energy V _h, in order to promoting m again _AIn time, used.As long as the energy △ V(of own loss is hereinafter to be referred as the supply energy in the continuous supply mechanical movement), m _ACan do dipping and heaving repeatedly.Experimental results show that △ V is much smaller than V _h, the available character of gravitional force that Here it is.

In addition, through calculating: 1. the effective potential of potential energy elevator is 4:1 with the ratio of supply energy; 2. make same merit, the elevator power consumption is 7.4:1 with the ratio of potential energy elevator supply energy.

Energy supply mode of the present utility model can select by the purposes of elevator " artificial potential energy supply " and (or) " electric power supply ".

For " artificial potential energy supply " mode is described, with 15 layers of residential building that the potential energy elevator is housed is example, when the resident goes upstairs, can elevator ride more than the 4th buildings, like this, the ratio that the number of plies in building (complementary energy) is stepped in elevator ride (power consumption) and walking is 4:1, seizes the opportunity whole process in the time of downstairs and reduces to ground (accumulation of energy), and the energy difference of accumulation of energy and power consumption can guarantee that as the supply energy potential energy elevator leans on the gravitional force long-term work and satisfies the needs of resident living.

" electric power supply " charges into pressurized air by air compressor to the high pressure tank of potential energy elevator and realizes that expend the electric power that is equivalent to the elevator sixth, the potential energy elevator just can be worked with elevator the samely.

Below in conjunction with accompanying drawing structure of the present utility model is described.

The utility model mainly stores device etc. by power conversion, safety speed-limit and energy and forms.

The bar chain (9) that " counterweight " of elevator car is unified into for two half racks, the center bearing pilot bearing encapsulation of every pole is stitching along slide rail on the slide block axle (8) of (6) moving linearly, the upper end of bar chain connects with steel cable (2) jail of traction car, and lower end and jail, ground connect.The joint number of bar chain (9) is with building Gao Erding, the length of every pole is decided with car base length, change the distance of any one group of adjacent sliders (7), promptly changed the angle of this adjacent stems, bar rotates to an angle around slide block (7), complete all bars of chain rotate same angle thereupon, and the slide block at complete each bar center of chain also changes adjacent distance simultaneously.If the always flexible distance of full chain is △ H, full chain bar number is n, then ∑ H=n △ H.The design controls the full chain of minimum slide block spacing actuating flexible of bar chain with this.

When empty car (3) when resting in top layer, bar chain (9) level under the deadweight effect is horizontal in extreme lower position, because half gear (10) and adjacent stems interlock at two ends are arranged between every pole, so externally show the gross weight of full chain, during car (3) descending motion, when bar chain integral body rises thereupon between each bar angle also open thereupon, car movement speed is sum of the two, the weight that is bar chain alleviates relatively, for storing potential energy, recovery provides condition, during the car upward movement bar chain when weight traction car rises as a whole between bar angle close up, the ascending velocity of car is a sum of the two, so laborsaving relatively, energy-conservation.
