Embodiment
The invention provides a kind of counterweight automatic loading device to comprise: counterweight hanger 1 and load maintainer.
Counterweight hanger 1 comprises: rectangle hanger 2, main suspension rod 4, web member 3, multiple counterweight hanger pole 5; Load maintainer comprises: fix half arc bucket 6, movable half arc bucket 7, bearing pin 8, load bucket base 9, multiple loading bucket inner support 10, mounting flange 11, spiral lift 12, multiple guiding parts 13 and motor 14; By loading bucket base 9, fix half arc bucket 6 and movable half arc 7 barrels forms the loading bucket with hierarchical organization.
Motor 14 is three composite stepper motors, is connected with spiral lift 12 by shaft coupling.
Spiral lift 12 one end is fixed in mounting seat 15, and mounting seat 15 is one-piece construction, is fixed on cement ground; Spiral lift 12 other end is connected with mounting flange 11, loads bucket base 9 and is fixed on mounting flange 11.
Guiding parts 13 is made up of two parts, and a part is fixing bobbin, is welded in mounting seat 15; Another part is slide bar, is threaded connection to be fixed on to load on bucket base 9, and can slide certain distance simultaneously in fixing bobbin.Rotated by the circumference of fixing bobbin constraint slide bar, and then constraint loads the circumferential movement of bucket.Preferably, guiding parts quantity is 3.
Fix half arc bucket 6 and movable half arc bucket 7 to be fixed on and to load on bucket base 9.
Fixing half arc bucket 6 is parts motionless in the put procedure of counterweight 16, and counterweight 16 is the general counterweight of F1 level of band " U " type short slot; Fix half arc bucket 6 to be made up of the half arc plate of fixing that multiple structures are from bottom to up identical, single to fix between half arc plate and fix half arc plate and load symmetrical respectively by three group switching centres between bucket base 9, angle be that the screw assembly of 60 ° is locked.
Movable half arc bucket 7 is identical with size with the version of fixing half arc bucket 6, movable half arc bucket is made up of the activity half arc plate that multiple structures are from bottom to up identical, each movable half arc plate is connected by the half arc plate of fixing that bearing pin is corresponding with it, movable half arc plate is rotated by bearing pin 8 and opens or closes loading bucket, realizes putting into and taking out of multiple counterweight 16.
Each fix half arc plate corresponding with it activity half arc plate composition one son load bucket, multiple son load bucket from bottom to up connect to form the loading bucket with multilevel hierarchy.
Load fixed support when bucket inner support 11 does not load for counterweight 16, it is " T " structure, tangent with loading bucket inwall, is connected by screw; Load bucket inwall circumference at son at different levels and angularly arrange 4 loading bucket inner supports, eachly fix half arc plate, movable half arc plate inwall respectively arranges 2, the loading bucket inner support that son at different levels loads bucket be equidistant layout; Load bucket inner support 11 supporting bable tops and become stepped, the placement of the large miniweights of different size can be realized.
Counterweight hanger is used for bearing support when counterweight loads, main suspension rod 4 is connected with rectangle hanger 2 by web member 3, every two counterweight hanger poles 5 one-tenth 60 ° of angles are welded on main suspension rod 4 by fixture, form multistage counterweight hanger branching rod structure, every grade of counterweight hanger pole 5 becomes along main suspension rod 4 axis direction equidistantly arranges, its spacing is equal with the spacing loaded between bucket inner support 11.During wind tunnel balance calibration, rectangle hanger 2 is connected with balance calibration loading head, realizes adding/unloading of weight load.
The rotary motion of motor 14 drives spiral lift 12 to work, the slide bar of guiding parts 13 is utilized to slide in fixing bobbin, and then drive loading bucket to move up and down realize counterweight 16 and load the disengaging of bucket inner support 10 and the contact with counterweight hanger pole 5, finally realize the automatic loading of counterweight 16.By the rotation number of turns and the rotating speed of motor 14, realize the automatic compression and decompression of varying number counterweight 16.
Counterweight automatic loading device specific implementation process of the present invention is used to comprise the steps:
The placement of S1, counterweight.Initial position, the supporting surface 3mm lower than the supporting surface loading bucket inner support of uppermost counterweight hanger pole; Loading bucket inner support puts into first counterweight; Bottom of closing first activity half arc bucket, puts into second counterweight; Up close last half arc bucket (the 7th) successively, puts into the 8th counterweight, complete the placement of counterweight.
The loading of S2, counterweight.Spiral lift rotates, and loads bucket and walks downward, be greater than reserved spacing, can load first counterweight on counterweight hanger pole, design 6mm; Continue the 6mm that walks downward, complete the loading of second counterweight; The like, walk downward 48mm, completes the loading of all 8 standards counterweights.
The unloading of S3, counterweight.Completely contrary with loading procedure.
The taking-up of S4, counterweight.After having unloaded, the state loading bucket and support got back to again by counterweight.First, 1 counterweight of the top is taken off; Then open loading bucket and go up an activity half arc plate most, take off the 2nd counterweight; The like, open and load the most next movable half arc plate of bucket, take off the 8th counterweight.
The embodiment of just this invention described in instructions.Although describe embodiments of the present invention by reference to the accompanying drawings, in this area, those skilled in the art can make various distortion or amendment within the scope of the appended claims.
