From Fig. 2, Fig. 3 and Fig. 5 as can be known, last link 4 by former and later two end plates, about two frameworks that side plate is formed; The connecting axle of its plate below, left and right sides links to each other by bearing pin 21 with the U type ear seat at two ends, the left and right sides, casing 1 top.
As can be seen from Figure 2, pendulous device is made up of an oscillating oil cylinder 11, two equalizing valves 9, valve piece 10, two oil cylinder holders 12; Oscillating oil cylinder 11 and valve piece 10 are manufactured in aggregates, and equalizing valve 9 is installed on the valve piece 10; Oscillating bearing in oscillating oil cylinder 11 heads is connected by bearing pin 7 with the otic placode in casing 1 outside; Its middle part diaxon is connected by pin with two oil cylinder holders 12 respectively, and oil cylinder holder 12 is fixed on the outside of junction plate of link 4.What be that oscillating oil cylinder 11 adopts is head earrings type, the fixed form of middle bearing pin type.
As can be seen from Figure 4, pendulous device is a cover, and it is installed in a side of casing 1.The specification that this kind mode is applicable to hydraulic crawler excavator hour.
As can be seen from Figure 9, as a kind of optimal way of the present utility model, pendulous device is two covers, and promptly oscillating oil cylinder 11 is two, is installed in the both sides of casing 1 symmetrically.This kind mode is applicable to that two oil cylinders of this moment connected by parallel way when the specification of excavator was big, and promptly the rod chamber of an oil cylinder communicates with another oil cylinder rodless cavity, makes the synchronously flexible of two oil cylinders.When oil cylinder is done stretching motion, casing and down link along with the wallowing motion of flexible realization ± 40 of oil cylinder °.
From Fig. 2, Fig. 5 as can be known, quick access device is made up of following link 8, rotary disk 22, the fast replacing device that is arranged on down in the link 8; Following link 8 by former and later two end plates, about two frameworks that side plate is formed; Rotary disk 22 is fixed on down the top of link 8, and it is connected with worm gear 17 by flat key 20, and links into an integrated entity by bolt 19 and worm gear 17, sliding support 15, and the centre of gyration of its centre of gyration and casing 1 coincides.Flat key 20 can also be born rotation torque when playing the role of positioning.
Fast replacing device wherein is divided into two kinds of forms:
Fig. 5, Fig. 6 represent is wherein a kind of, and it comprises quick change oil cylinder 18, the quick change headstock 24, bearing pin 29, quick change head 2, spring 23; The quick change headstock 24 is connected on the piston rod of quick change oil cylinder 18, and bearing pin 29 is fixed on down on the left plate of link 8, and it passes from quick change oil cylinder 18 rear end earholes; Spring 23 is positioned at the both sides of quick change oil cylinder 18, and the one end links to each other with the left plate of following link 8, and the other end links to each other with quick change head 2; Quick change head 2 passes from the right plate 6 of following link 8.This kind situation is the quick connection that connects accessory under the flexible realization by quick change oil cylinder 18: quick change oil cylinder 18 oil inlet and outlets are connected fuel feeding by hydraulic hose with swivel coupling 14 hydraulic fluid ports, and its two chamber normal open hydraulic oils utilize the differential locking of two cavity areas.When need unloading facility, the control reversal valve makes cylinder rod chamber advance hydraulic oil, and rodless cavity leads to oil return, and quick change oil cylinder 18 reclaims compression spring 23, makes 2 withdrawals of quick change head.The spring 23 that contracts has certain pre compressed magnitude, guarantees quick change oil cylinder 18 under the release situation, and accessory can not come off, thereby improves Product Safety.Can be implemented in the quick accessory of changing under the non-stop-machine situation in such cases.
Fig. 7, Fig. 8 represent is wherein another kind, and it comprises the flexible headstock 31, pulls pin 32, quick change head 2, spring 23; Pulling pin 32 is connected down on the left plate 34 of link 8 by axle 33; Pull pin 32 upper ends and be processed with a hole, the other end contacts with the wedge surface of the flexible headstock 31; Spring 23 is positioned at the both sides of the flexible headstock 31, and the one end is loaded in the flexible headstock 31, and the other end is loaded in the spring back seat 35; One of quick change head 2 links to each other with spring 23, and the other end passes from left plate 34.This kind situation is to utilize lever principle to realize connecing down the quick connection of accessory: outer when belonging to utensil when changing, and crowbar inserted pull in pin 32 holes, pull downwards it is rotated around axle 33, make the wedge surface compression spring 23 of the flexible headstock 31 that quick change head 2 is withdrawn.Contact the spacing spring 23 that makes with the wedge surface upper surface and be in compressive state when pulling pin 32.Insert accessory this moment, and upwards pin 32 is pulled in swing, and quick change head 2 is locked accessory under the effect of spring force, finish Fast Installation.
From Fig. 2, Fig. 5 as can be known, the hydraulic control valve group comprises four groups of reversal valves 13, overflow valve 3, valve piece 30, swivel coupling 14; Reversal valve 13, overflow valve 3 are installed on the valve piece 30, and valve piece 30 is fixed on casing 1 upper surface; Swivel coupling 14 is positioned at the centre bore of sliding support 15, and its shell body is fixed on the valve piece 30, and revolving body is fixedlyed connected with rotary disk 22 in it.Like this, when worm screw 27 rotations, drive worm gear 17, rotary disk 22 rotate together, thereby the interior revolving body that drives swivel coupling 14 rotates the shell body transfixion of swivel coupling 14 with following link 8.
When oscillating oil cylinder 11 stretched, link 8 rotated around bearing pin 7,21 under drive casing 1 reached, thereby realization is center ± 40 ° of swings with the X-axis.The shuttle speed of oscillating oil cylinder 11 is regulated by equalizing valve 9.
When hydraulic motor 25 work, it drives worm screw 27 rotations, worm screw 27 is passed to power on the worm gear 17 that is meshed with it, link 8 rotates around the centre of gyration line of casing 1 under rotary disk 22 that worm gear 17 drives are fixedlyed connected with it and further the drive, thereby realizes with the Z axle being 360 ° of revolutions at center.
Universal quick connecting connector of the present utility model is connected with main frame by the last link 4 on top, its connected mode has two kinds: a kind of bearing pin 5 that passes through is connected with connecting rod with the dipper of main frame, a kind of that bearing pin 5 and last link is integrally welded, on connect common excavator hydraulic quick coupler.
During assembling, with each oil circuit conducting, and connect control circuit with hydralic hose.In the process of implementing operation, the operator by electric control operation system control hydraulic valve bank, realizes the commutation of the reversal valve in the hydraulic valve bank in driver's cabin.When the logical oil of hydraulic motor 25, drive worm screw 27 and rotate around X-axis, drive worm gear 17 is done gyration around the Z axle, and has auto-lock function.Because worm gear 17 is fixed by rotary disk 22 and following link 8 to be one, thereby makes the rotation of facility around ± 360 ° in Z axle work; Simultaneously, when the logical oil of oscillating oil cylinder 11, flexible by oil cylinder, make casing 1 and down link 8 can X-axis be that swing at the center, its pendulum angle is about ± 40 °.The assisted mining machine changes the stretching motion of hammer oil cylinder in addition, and all mechanisms of universal quick connecting connector and lower end can be rotated around Y-axis.
So, universal quick connecting connector of the present utility model can around self ± 360 ° of rotations, can tilt with accessory self neutral plane ± 40 ° again, flexible 120 ° of rotations up and down of secondary master bucket arm cylinder simultaneously, thus realization is to the rotation compound motion of space three coordinate axes X, Y, Z three degree of freedom.Simultaneously, owing to have quick replacing accessory function, expand the working range and the efficient convenient work capacity of main frame, can realize down connecing that accessory is comprehensive, the operation of multi-angle, improved the operating efficiency of main frame greatly.
