Detailed description of the invention
Referring to figs. 1 through Fig. 6, a kind of pneumatize hoisting supporting mechanism, comprise base 1, stepping motor 5, micro controller system 16, travel switch 14, relay 15, trapezoidal threaded lead screw 9, inside and outside cylinder lifting bar 3, air pressure telescopic link 2, cylindrical guide 7, single pole double throw switch, described cylindrical guide 7 is fixedly connected on described base 1 by guiderail base; The top of described cylindrical guide 7 is provided with trapezoidal threaded lead screw 9, rotating being connected in described trapezoidal threaded lead screw 9 one end is fixed on the aluminium block 10 of base 1, the other end is connected with stepping motor 5 by coupler 11, and described stepping motor 5 is fixed on base 1 by motor base 6; Described cylindrical guide 7 is also provided with can along the guide rail slide block 13 of described cylindrical guide 7 movement, described trapezoidal threaded lead screw 9 is provided with flange nut 12 and square steel 8, described flange nut 12 is fixedly connected with one end of described square steel 8, the two ends of described square steel 8 are respectively equipped with a contact, are fixed together bottom described square steel 8 with described guide rail slide block 13;
The two ends of described cylindrical guide 7 are respectively arranged with travel switch 14, and the height of the contact at described square steel 8 two ends is highly equal with described travel switch 14;
Described relay 15, described travel switch 14, described single pole double throw switch connect described micro controller system 16 respectively; Described relay 15 is also connected with described stepping motor 5;
Described inside and outside cylinder lifting bar 3 is made up of interior bar 31 and outer bar 32, and described interior bar 31 is fixedly installed on described base 1, and described outer bar 32 can rise along bar 31 in described and decline; The top of described inside and outside cylinder lifting bar 3 arranges one for holding the pallet 4 of weight;
One end of described air pressure telescopic link 2 is hinged on described square steel 8, and the other end is hinged on described outer bar 32 near lower end.
Further, described stepping motor 5 is three, and angle is 120 ° each other.
Further, described inside and outside cylinder lifting bar 3 is arranged on the center of described base 1.
Further, described inside and outside cylinder lifting bar 3 is fixed on described base 1 by corner fittings 17.
Further, described cylindrical guide 7 and trapezoidal threaded lead screw 9, in same perpendicular, are avoided the extra moment that produces on other direction and go to disturb lifting process.
When rising weight, single-pole double throw (SPDT) travel switch is thrown to side, at this moment, the micro controller system be connected with travel switch sends instructions to relay after receiving this signal, and stepping motor is opened and rotated forward, driving torque when stepping motor rotates drives trapezoidal threaded lead screw to rotate, make the flange nut in trapezoidal threaded lead screw produce relative movement, thus drive square steel and guide rail slide block to move, simultaneously, the air pressure telescopic link hinged with square steel extends, and promotes inside and outside cylinder lifting bar and rises.When moving to the contact on square steel and touching travel switch, motor stalls; In like manner, when putting down weight, single pole double throw switch is thrown opposite side, after micro controller system receives signal, issue instructions to relay, motor is opened and reversion, inside and outside cylinder lifting declines, until the opposite side contact on square steel touches travel switch, motor stalls.
In order to ensure that this hoisting supporting mechanism has the load of higher structural strength and base to be evenly distributed, avoid inside and outside cylinder lifting bar due to load-carrying excessive and cause base transship distortion, the utility model have employed three inside and outside cylinder lifting bars of air pressure telescopic link collocation, and be provided with guide rail slide block along with square steel and move together, make air pressure telescopic link obtain large support in moving process always, ensure that stability and the reliability of this mechanism to a great extent.
In the starting stage of lifting, the moment of torsion that stepping motor exports makes air pressure telescopic link level of approximation move, and along with the rising of inside and outside cylinder lifting bar, the Pneumatic pressure of air pressure telescopic link itself promotes the rising of lifting bar until terminal.And the value that now every root air pressure telescopic link assigns to weight gravity is minimum, the disturbance of weight at vertex not by other factors reliablely and stablely can be ensured.Simultaneously, in the process that weight declines, stepping motor promotes air pressure telescopic link and back moves, along with miles of relative movement increases, angle between air pressure telescopic link and trapezoidal threaded lead screw is more and more less, then the component of weight that is subject to of air pressure telescopic link is just increasing, the gravity of weight thus can be utilized to enable air pressure telescopic link get back to the shortest initial conditions, thus realize " little power rises energetically " Machine Movement Process cleverly.
