The pneumatic elevator of traction-type of the present invention is after stopping, and variable-weight car 1 and variable-weight counterweight 2 are in state of equilibrium.After having people to enter variable-weight car 1, the overall weight of variable-weight car 1 increases, and under the application force of variable-weight car 1, floating part 321 is to lopsidedness; Now, first elastic component 322 is compressed and is contacted with the first travel switch 324, first travel switch 324 is closed, thus the one end making change counterweight electromagnetic valve 44 be connected with the first air chamber 51 is energized, the pressurized air in air compression station 41 enters in the first air chamber 51 through becoming counterweight electromagnetic valve 44.After pressurized air enters the first air chamber 51, under gas pressure, the first diaphragm plate 53 is compressed, liquid in first liquid chamber 52 is forced out, the liquid extruded enters in second liquid chamber 62 through oil pipe, the weight of the first liquid gas converter 5 is reduced, and the weight of the second liquid gas converter 6 increases.Meanwhile, when the liquid in second liquid chamber 62 increases, the second diaphragm plate 63 is to the second air chamber 61 1 side compression under hydraulic action, and the gas in the second air chamber 61 is forced out.Along with the increase of the load-carrying of variable-weight car 1, liquid in first liquid chamber 52 flow in second liquid chamber 62 gradually, the overall weight of the overall weight of variable-weight car 1 and variable-weight counterweight 2 is tended to balance gradually, until variable-weight car 1 and variable-weight counterweight 2 reach new balance.Close the railway carriage or compartment door of variable-weight car 1, after variable-weight car 1 and variable-weight counterweight 2 reach balance, first elastic component 322 leaves the first travel switch 324, first travel switch 324 disconnects, thus the compression control in air compression station 41 stops entering in the first air chamber 51, start air motor 311, variable-weight car 1 runs.Thus, after variable-weight car 1 and variable-weight counterweight 2 reach new balance, decrease the output torque of air motor 311, decrease energy consumption.
In like manner, when the load-carrying of variable-weight car 1 reduces, floating part 321 tilts to opposite side, second elastic component 323 contacts the second travel switch 325, second travel switch 325 closes, and one end that change counterweight electromagnetic valve 44 is connected with the second air chamber 61 is energized, and pressurized air enters the second air chamber 61.Under compressed-air actuated effect, the second diaphragm plate 63 is compressed, and the liquid in second liquid chamber 62 is pressed out to first liquid chamber 52, thus the weight of the second liquid gas converter 6 is reduced, and the weight of the first liquid gas converter 5 increases.Meanwhile, along with the increase of liquid in first liquid chamber 52, the first diaphragm plate 53 is to the first air chamber 51 1 side compression under hydraulic action, and the gas in the first air chamber 51 is forced out.Finally make the balance that the overall weight of the overall weight of variable-weight car 1 and variable-weight counterweight 2 reaches new, the second elastic component 323 leaves the second travel switch 325, second travel switch 325 and disconnects, and pressurized air stops entering the second air chamber 61.Close railway carriage or compartment and start air motor 311 behind the door, variable-weight car 1 runs.
After starting air motor 311, one end energising of lifting electromagnetic valve 432, pressurized air enters in air motor 311 through meter in valve 431 and lifting electromagnetic valve 432, and drives air motor 311 to rotate forward, and air motor 311 drives variable-weight car 1 to rise.Meanwhile, pressurized air enters in drg 312 through shuttle valve 33, and the brake shoe brake cheek in drg 312 is opened air motor 311.Otherwise after the other end energising of lifting electromagnetic valve 432, air motor 311 reverses, and air motor 311 drives variable-weight car 1 to decline.
Thus, the pneumatic elevator of traction-type of the present invention, by the mutual flowing of both the first liquid gas converter 5 and the second liquid gas converter 6 liquid, realize when the load-carrying of variable-weight car 1 changes, variable-weight car 1 and variable-weight counterweight 2 keep balance, ensure that variable-weight car 1 operationally consumes energy low, substantially reduce output torque, improve the durability of CD-ROM drive motor 311, improve service life.
In order to ensure the safety that variable-weight car 1 can operate steadily and use, need to carry out speed governing to it in variable-weight car 1 operational process.When variable-weight car 1 stops, the opening of governor valve 424 is minimum, variable-weight car 1 is in lifting process, and speed governing electromagnetic valve 422 is energized, and the pressurized air of air compression station 41 enters into speed governing cylinder 423 through reducing valve 8, speed regulation throttle valve 421 and speed governing electromagnetic valve 422.Now, spring in speed governing cylinder 423 is compressed, the opening of governor valve 424 increases, namely compressed-air actuated suction quantity increases, thus the pressurized air increase of lifting electromagnetic valve 432 is entered through governor valve 424, the suction quantity of air motor 311 increases, and its faster rotational speed, makes the running velocity of variable-weight car 1 accelerate.Before variable-weight car 1 operation is arrived at a station, speed governing electromagnetic valve 422 power-off, pressurized air stops entering in speed governing cylinder 423, and the pressure gas in speed governing cylinder 423, under the effect of the bounce of spring, is discharged through speed governing electromagnetic valve 422 and speed regulation throttle valve 421; The opening of governor valve 424 reduces simultaneously, and the air entering lifting electromagnetic valve 432 through governor valve 424 reduces, thus the running velocity of variable-weight car 1 slows down, and stops when arriving at a station.
Above-described is only the preferred embodiment of the present invention, it should be pointed out that for the person of ordinary skill of the art, and without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
