Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
As Figure 1-3, one of the present invention singly drives synchronization lifting mechanism, forms primarily of main drive gear and 4 cover elevator assemblies; Wherein, 4 cover elevator assemblies are distributed in circumferentially same;
Described main drive gear comprises alternating-current motor/AC motor 5, first main gear belt wheel 6, second main gear belt wheel, belt wheel minor axis 4, Timing Belt 3, tension wheel 7, coupler 8,4 elevator driven pulleys 9 and tween drive shaft 12; Described elevator assembly comprises elevator transmission shaft 10, worm-and-wheel gear 14, lifting screw 15 and pallet 16;
Annexation is: the output shaft of alternating-current motor/AC motor 5 and the first main gear belt wheel 6 key connecting, and the first main gear belt wheel 6 is connected with one end of tween drive shaft 12 by belt wheel minor axis 4 and coupler, the other end of tween drive shaft and the second main gear belt wheel key connecting; 4 elevator driven pulleys 9 overlap elevator transmission shaft 10 key connecting on elevator assembly respectively with 4, two elevator driven pulleys 9 and the tension wheel 7 of the first main gear belt wheel 6 and the first main gear belt wheel 6 homonymy are in transmission connection by Timing Belt 3; Two elevator driven pulleys 9 and the tension wheel 7 of the second main gear belt wheel and the second main gear belt wheel 6 homonymy are in transmission connection by Timing Belt 3; Elevator transmission shaft 10 is connected with lifting screw 15 by worm-and-wheel gear 14, and pallet 16 is fixed on the top of lifting screw 15.
In the present invention, the output shaft of alternating current dynamo 5 and the first main gear belt wheel 6 are by key connecting, output power to main gear belt wheel 6.First main gear belt wheel 6 is connected with one end of tween drive shaft 12, by power transmission to tween drive shaft by belt wheel minor axis and coupler 8 simultaneously.Power transmission, by key connecting, is given the second main gear belt wheel by the other end of tween drive shaft 12 and the second main gear belt wheel.The driving pulley 6 of both sides by Timing Belt 3 and tension wheel 7 by transmission of power on elevator driven pulley 9, drive elevator transmission shaft 10 to rotate as shown in Figure 2.Elevator driven pulley 9 and elevator transmission shaft 10 fetch transferring power by binding, elevator transmission shaft 10 will change the dipping and heaving of lifting screw 15 into by the high precision worm-and-wheel gear 14 of elevator inside, and pallet 16 and lifting screw 15 are thread connection.Transversely worm-and-wheel gear 14 transmission direction of two pairs of elevators that is arranged symmetrically with of center line is contrary, and the worm screw of its a pair elevator is left-hand worm, then another is right-hand worm to the worm screw of elevator.Therefore rise and fall while the present invention can realize 4 cover elevator assemblies, it has higher stability.
The output shaft of alternating current dynamo 5 is supported by bearing seat in the present invention, the two ends of tween drive shaft 12 are supported by bearing seat, tension wheel 7 and elevator driven pulley 9 support by bearing seat, bearing seat is fixed on pedestal, the bearing seat of tension wheel 7 is adjustable in short transverse, for regulating the tensile force of toothed belt transmission.
The center of lifting screw 15 on 4 cover elevator assemblies is preferably made to be distributed in circumferentially same in the present embodiment.
One of the present invention singly drives synchronization lifting mechanism, before the use, needs to adjust the position of pallet 16 on lifting screw 15, makes 4 pallets 16 in same level, and fixed by the relative position of pallet 16 with lifting screw 15 with holding screw.After the level of synchronization having adjusted 4 pallets 16, this list drives synchronization lifting mechanism can make 4 pallet 16 synchronization liftings and be at any time in same level under the drive of alternating-current motor/AC motor 5, promotes the load/unload of standard test weight.
Below for alternating current dynamo left-hand revolution, working process of the present invention is described:
Alternating-current motor/AC motor 5 drives main gear belt wheel 6 to rotate counterclockwise, tension wheel 7 rotates clockwise under the drive of the Timing Belt 3 pulled by main gear belt wheel 6, elevator driven pulley 9 is driven to rotate counterclockwise by toothed belt transmission afterwards, the elevator transmission shaft 10 of elevator driven pulley 9 and No. 2 elevators 2 is by key connecting transmission, as input, drive the pallet 16 upwards straight-line motion of No. 2 elevators 2.In like manner, the elevator transmission shaft 10 of No. 3 elevators 11 is also driven by alternating-current motor/AC motor 5 and rotates counterclockwise, thus drives the pallet 16 upwards straight-line motion of No. 3 elevators 11.Simultaneously, alternating-current motor/AC motor 5 drives tween drive shaft 12 to rotate counterclockwise, the elevator transmission shaft of No. 1 elevator 1 and No. 4 elevators 13 is driven to rotate counterclockwise, because No. 1 elevator 1, No. 4 elevators 13 and No. 2 elevators 2, No. 3 elevators 11 transversely center line are arranged symmetrically with, and No. 1 elevator 1, No. 4 elevators 13 are contrary with No. 2 elevators 2, No. 3 elevator 11 hands of worms, therefore drive the pallet 16 upwards straight-line motion of No. 1 elevator 1, No. 4 elevators 13.Due to 4 cover elevators 1,2,11,13 identical, and before use each elevator pallet 16 is adjusted to same level, therefore, under the driving of separate unit alternating-current motor/AC motor 5,4 cover elevator 1,2,11,13 synchronization liftings, and be at any time in same level.Need to carry out synchronization lifting to standard test weight while carrying out load/unload to standard test weight, in load/unload action, the center of circle that place, the lifting screw 15 center circle of elevator 1,2,11,13 need be overlapped with 4 in the center of circle of standard test weight overlaps, with this understanding, this single driving synchronization lifting mechanism can be stablized and carry out descending operation without inclined to standard test weight.
In sum, these are only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
