sequence of mechanical actions of the whole device:
when the lifting mechanism starts to work, goods are placed on the upper side of the lifting plate 15, then the lifting motor 25 is started to drive the spline shaft 24 to rotate, so that the steering switching shaft 21 is driven to rotate, so that the reverse bevel gear 23 and the forward bevel gear 13 are driven to rotate, at the moment, the forward bevel gear 13 and the steering bevel gear 73 are in a meshed state, so that at the moment, the forward bevel gear 13 drives the steering bevel gear 73 to rotate, so that the screw rod 17 is driven to rotate, so that the lifting slider 16 is driven to move upwards, so that the lifting plate 15 is driven to move upwards, and when the lifting slider 16 drives the main triggering magnetic block 35 to move upwards to just correspond to the auxiliary triggering magnetic block 46, at the moment, the repulsive force between the main triggering magnetic block 35 and the auxiliary triggering magnetic block 46 overcomes the resultant force of the pulling force of the main triggering spring 40, the pushing force of the inflating spring 55 and the pushing forces of the two auxiliary triggering springs 47, so that the auxiliary triggering magnetic block 46 is abutted against the pushing plate 37 rightwards, so that the push plate 37 moves rightwards and is just in a butt joint state with the auxiliary contact switch 53, so that the lifting motor 25 is turned off at the moment, the switching electromagnet 12 is started, the lifting plate 15 stops moving upwards at the moment, and the one-time lifting of the goods is finished at the moment;
if the initial lifting height of the goods needs to be changed, the friction force between the friction plate 32 and the main box body 10 is overcome at the moment, the height adjusting knob 34 is rotated in the forward direction, so that the height adjusting shaft 33 is driven to rotate, the wire wheel 43 is driven to rotate, the adjusting pull rope 42 is gradually loosened at the moment, the pulling force of the adjusting pull rope 42 is lost by the height adjusting slider 38 at the moment, the height adjusting slider 38 correspondingly moves upwards for a certain distance under the thrust of the height adjusting spring 41, the height adjusting slider 38 drives the auxiliary triggering magnetic block 46 to move upwards for a certain distance through the auxiliary triggering magnetic block cavity 45, so that the distance between the main triggering magnetic block 35 and the auxiliary triggering magnetic block 46 is increased, the upward moving distance of the lifting plate 15 is changed, namely the lifting height of the goods is changed;
when the main trigger magnetic block 35 corresponds to the auxiliary trigger magnetic block 46, the lifting motor 25 is turned off and the switching electromagnet 12 is turned on, so that the switching electromagnet 12 is energized, the attractive force between the switching electromagnet 12 and the switching magnetic block 20 overcomes the thrust of the switching magnet spring 11, so that the switching magnetic block 20 moves leftward, the switching magnetic block 20 drives the forward bevel gear 13 and the reverse bevel gear 23 to move leftward through the steering switching shaft 21, so that the forward bevel gear 13 and the steering bevel gear 73 are in a disengaged state, and the reverse bevel gear 23 and the steering bevel gear 73 are in an engaged state, so that when goods on the upper side of the lifting plate 15 are carried away, the lifting motor 25 is turned on again, so that the spline shaft 24 rotates, so that the forward bevel gear 13 and the reverse bevel gear 23 are driven to rotate through the steering switching shaft 21, and the reverse bevel gear 23 drives the steering bevel gear 73 to rotate reversely, thereby driving the lifting slide block 16 to move downwards, and further driving the lifting plate 15 and the main trigger magnet 35 to move downwards, and when the lifting slide block 16 moves to the initial position, namely, the lifting slide block is abutted against the main contact switch 18, at this time, the lifting motor 25 and the switching electromagnet 12 are closed, thereby realizing the descending reset of the lifting plate 15, and when the switching electromagnet 12 is closed, at this time, the forward rotation bevel gear 13 is in the meshing state with the steering bevel gear 73 again, so that the screw rod 17 can rotate forward again, namely, when the lifting motor 25 is started again, the lifting plate 15 can ascend again;
and when the lifting slide block 16 rises, the main triggering magnetic block 35 continuously corresponds to the auxiliary triggering magnetic block 46, the push plate 37 continuously abuts against the inflating piston 54 rightwards, so that the air in the inflating piston cavity 56 is pushed by the inflating piston 54 to enter the cargo monitoring cavity 28 through the inflating main cavity 57, the inflating auxiliary cavity 63 and the inflating check valve 58 and is positioned at the lower side of the pressure piston 61, and when the main triggering magnetic block 35 is separated from the auxiliary triggering magnetic block 46, the inflating piston 54 moves leftwards under the thrust of the inflating spring 55, so that the external air enters the inflating piston cavity 56 through the small exhaust port 67, the air inlet check valve 60 and the inflating main cavity 57, the air in the inflating piston cavity 56 can be stored again, and as the main triggering magnetic block 35 continuously corresponds to the auxiliary triggering magnetic block 46, the air in the cargo monitoring cavity 28 and positioned at the lower side of the pressure piston 61 is gradually increased, therefore, at the moment, the pressure piston 61 is acted by the pressure of air at the lower side of the pressure piston to overcome the thrust of the cargo quantity adjusting spring 31 to move upwards, and when the conveyed cargo reaches a certain quantity, the pressure piston 61 drives the pressure main magnetic block 62 to move upwards to be just in a corresponding state with the pressure auxiliary magnetic block 69, so that the repulsion force between the pressure main magnetic block 62 and the pressure auxiliary magnetic block 69 overcomes the thrust of the auxiliary magnetic block spring 71, the pressure auxiliary magnetic block 69 moves rightwards to be just in a butting state with the small contact switch 72, and the exhaust electromagnet 66 and the motor 49 are started at regular time;
