After stopping, variable-weight car 1 and variable-weight counterweight 2 are in poised state to the pneumatic extension elevator of the present invention.
After someone enters variable-weight car 1, the overall weight of variable-weight car 1 increases, and under the active force of variable-weight car 1, floats
Moving part 321 is to lopsidedness；Now, the first elastic component 322 is compressed and is contacted with the first travel switch 324, makes the first row
Cheng Kaiguan 324 closes, so that becoming one end energising that counterweight electromagnetic valve 44 is connected, air compression station with first gas chamber 51
Compressed air in 41 enters in first gas chamber 51 through becoming counterweight electromagnetic valve 44.Compressed air enters first gas chamber 51
Afterwards, under gas pressure, the first diaphragm plate 53 is compressed so that the liquid in first liquid chamber 52 is forced out, the liquid warp of extrusion
Oil pipe enters in second liquid chamber 62, so that the weight of the first liquid gas converter 5 is reduced, and the weight of the second liquid gas converter 6 increases
Plus.Meanwhile, when the liquid in second liquid chamber 62 increases, second diaphragm plate 63 is under hydraulic action to second gas chamber 61 1
Side compression, the gas in second gas chamber 61 is forced out.With the increase of the load-carrying of variable-weight car 1, in first liquid chamber 52
Liquid gradually flow in second liquid chamber 62 overall weight so that the overall weight of variable-weight car 1 and variable-weight counterweight 2
Gradually tend to balance, 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 reaches balance with variable-weight counterweight 2, the first elastic component 322 leaves the first travel switch 324, the first row
Cheng Kaiguan 324 disconnects, thus the compression control in air compression station 41 stops entering in first gas chamber 51, starts the first gas
Cylinder 91, variable-weight car 1 runs.Thus, after variable-weight car 1 and variable-weight counterweight 2 reach new balance, decrease BOGEY WHEEL
The weight difference of 311 both sides, decreases driving force and the energy consumption of the first cylinder 91.
In the same manner, when the load-carrying of variable-weight car 1 reduces, floating part 321 tilts to opposite side, and the second elastic component 323 connects
Touch the second travel switch 325, the second travel switch 325 closes, and so that change counterweight electromagnetic valve 44 is connected with second gas chamber 61
One end is energized, and compressed air enters second gas chamber 61.In the presence of compressed air, second diaphragm plate 63 is compressed, and second
Liquid in liquid chambers 62 is pressed out to first liquid chamber 52, so that the weight of the second liquid gas converter 6 reduces, the first liquid gas
The weight of converter 5 increases.Meanwhile, with the increase of liquid in first liquid chamber 52, the first diaphragm plate 53 is under hydraulic action
To first gas chamber 51 1 side compression, the gas in first gas chamber 51 is forced out.Finally make the entirety weight of variable-weight car 1
Amount reaches new balance with the overall weight of variable-weight counterweight 2, and the second elastic component 323 leaves the second travel switch 325, the second row
Cheng Kaiguan 325 disconnects, and compressed air stops entering second gas chamber 61.Close railway carriage or compartment and start the first cylinder 91, variable-weight sedan-chair behind the door
Railway carriage or compartment 1 is run.
After starting the first cylinder 91, a end energising of lifting electromagnetic valve 432, compressed air is through meter in valve 431 and lifting
Electromagnetic valve 432 enters in the cavity of the first cylinder 91, promotes First piston bar 911 protruding, drives on variable-weight car 1
Rise.Meanwhile, compressed air enters in brake 312 through shuttle valve 33, makes brake-shoe in brake 312 to BOGEY WHEEL 311 dozens
Open.Conversely, after lifting the b end energising of electromagnetic valve 432, First piston bar 911 is retracted and drives variable-weight car 1 to decline.
Thus, the pneumatic extension elevator of the present invention, by both the first liquid gas converter 5 and the second liquid gas converter 6
The mutual flowing of liquid, realizes in the case that the load-carrying of variable-weight car 1 changes, variable-weight car 1 and variable-weight counterweight 2 are protected
Maintain an equal level weighing apparatus it is ensured that variable-weight car 1 operationally consumes energy low, substantially reduces output torque, improve the resistance to of the first cylinder 91
Expenditure, improves service life.
In order to ensure the safety that variable-weight car 1 can operate steadily and use, in variable-weight car 1 running
Need to carry out speed governing to it.When variable-weight car 1 stops, the opening of flow speed control valve 424 is minimum, and variable-weight car 1 was lifting
Cheng Zhong, speed governing electromagnetic valve 422 is energized, and the compressed air of air compression station 41 is through air relief valve 8, speed regulation throttle valve 421 and speed governing electricity
Magnet valve 422 enters into speed governing cylinder 423.Now, the spring in speed governing cylinder 423 is compressed, and the opening of flow speed control valve 424 increases,
I.e. the air inflow of compressed air increases, thus increasing through the compressed air that flow speed control valve 424 enters lifting electromagnetic valve 432, the first gas
The air inflow of cylinder 91 increases, and its faster rotational speed is so that the speed of service of variable-weight car 1 is accelerated.When variable-weight car 1 runs to
Before standing, speed governing electromagnetic valve 422 power-off, compressed air stops entering into the compressed gas in speed governing cylinder 423, in speed governing cylinder 423
Body, in the presence of the bounce of spring, is discharged through speed governing electromagnetic valve 422 and speed regulation throttle valve 421；The opening of flow speed control valve 424 simultaneously
Mouth reduces, and reduces through the air that flow speed control valve 424 enters lifting electromagnetic valve 432, thus the speed of service of variable-weight car 1 slows down,
Stop when arriving at a station.
Above-described is only the preferred embodiment of the present invention it is noted that for those of ordinary skill in the art
For, without departing from the concept of the premise of the invention, some deformation can also be made and improve, these broadly fall into the present invention
Protection domain.
