Mechanism 3, quick changing oil cylinder 4.
Accessory connection frame 1 is by side plate 11, lower support shaft 12, left guideway 13, body cradle 14, erection support 15, the right side
Guideway 16, cylinder pedestal 17, side plate stiffening plate 18, lifting lug 19, upper support shaft 110 and connecting plate 111 form.Wherein, on
Support shaft 110 is arranged in parallel with lower support shaft 12, upper support shaft 110, lower support shaft 12 both ends side plate 11 is respectively set, often
The top setting one of a side plate 11 can be used for installing the groove of long axis 2 or accessory.It is arranged on the outside of the side plate 11 of groove corresponding position
Long axis lockable mechanism 112, installation and locking for long axis 2 and accessory improve safety when accessory uses.In side plate
Groove on 11 is additionally provided with side plate stiffening plate 18, to receiving long axis 2 and accessory etc. on side plate 11 compared with the groove of big load
Place is reinforced.Body cradle 14 is fixedly installed in lower support shaft 12, be articulated and connected plate 111 on body cradle 14, connecting plate 111
Top has a groove identical with the groove height on side plate 11, is used to support long axis 2 and accessory.In lower support shaft 12 also
An erection support 15 is fixedly installed.The lower part of side plate 11 is provided with through-hole 113, and left guideway 13, right guideway 16 are welded on
In lower support shaft 12, guideway axis is overlapped with 113 axis of through-hole on side plate.Quick change link mechanism 3 passes through erection support
15, left guideway 13 and right guideway 16, which are defined, is mounted on accessory connection frame 1.Lifting lug 19 is welded on support shaft
On 110, stablize plumbness by being in accessory connection frame 1 after the lifting accessory connection frame 1 of lifting lug 19, convenient and engineering machinery
Assembly connection.One cylinder pedestal 17 is set towards the direction of erection support 15 on one of side plate 11, is changed oil fastly for installing
Cylinder 4.
4 bottom of quick changing oil cylinder is hinged on cylinder pedestal 17；Quick changing oil cylinder 4 makes quick change for driving quick change link mechanism 3
The both ends of link mechanism 3 are used for fixed race by the through-hole 113 on left guideway 13, the protruding side plate 11 of right guideway 16
Tool.
Long axis lockable mechanism 112 is mainly made of snap-gauge 1121, bent plate 1122, bolt 1123, axis 1124, pin 1125.Card
There is plate 1121 grab and one to be suitble to the hand-held hand-held part pulled.Snap-gauge 1121 by axis 1124 be mounted on bent plate 1122(or
Side plate 11) on, and can be rotated around axis 1124；Snap-gauge 1121 arbitrarily rotates in order to prevent, and setting one can penetrate bent plate 1122(or side
Plate 11) and snap-gauge 1121 bolt 1123, be kept fixed snap-gauge 1121 with respect to the position of side plate 11, when bolt 1123 is extracted
When, then snap-gauge 1121 can be rotated.Axis 1124 is mounted in the axle sleeve on bent plate 1122 by pin 1125.
Quick change link mechanism 3 is mainly formed by connecting by sliding pin 31, connecting rod 32 and intermediate plate 33.Intermediate plate 33 passes through washer
5 are rotatably coupled on the erection support 15 on accessory connection frame 1, and the both ends of intermediate plate 33 are hinged with a connecting rod 32 respectively,
Connecting rod 32 is hinged with sliding pin 31 again.Wherein one end of intermediate plate 33 and 32 hinged place of connecting rod, by bolt 34 and nut 35 with
The forked type cylinder head of 4 front end of quick changing oil cylinder is attached.Two sliding pins 31 are separately positioned on left guideway 13 and right guiding axis
It can slide in set 16 and without interference.When sliding pin 31 slides in and out stretching, it can be inserted correspondingly into the through-hole 113 of side plate, be used for
Fixed accessory.Because of foozle, it cannot be guaranteed that the axis of quick changing oil cylinder 4 and intermediate plate 33 be in same plane, by centre
Increase washer 5 between plate 33 and the hinge joint of erection support 15, intermediate plate 33 and 4 axis of quick changing oil cylinder are guaranteed by adjusting washer (disk) 5
In same plane.
Accessory quick-changing mechanism of the invention is assembled according to the following steps:
Firstly, sliding pin 31, fishplate bar 32, the intermediate plate 33 in quick change link mechanism 3 are loaded by bolt 34,35 groups of nut
Come.Then, intermediate plate 33 is mounted on by the erection support 15 on accessory connection frame 1 by bolt, sliding pin 31 is inserted into a left side respectively
When can be slided without interference in guideway 13 and right guideway 16, and guarantee that sliding pin 31 is moved to both sides outermost locations
It can be inserted into the through-hole 113 of side plate, play the role of fixed accessory.Then, bolt 1123 is extracted, snap-gauge 1121 is rotated, makes card
Long axis 2 or accessory, can be placed on accessory connection frame side plate by the groove on completely unobstructed 11 top of side plate of the grab of plate 1121
11 and 111 top of connecting plate groove in, then go back to snap-gauge 1121 and be inserted into bolt 1123, make the grab of snap-gauge 1121 from top
Hook long axis 2, it is ensured that long axis 2 is limited in a groove by snap-gauge 1121, and stopping long axis 2 or accessory will not be from working condition
It is fallen off on side plate 11.Finally, 4 forked type cylinder head of quick changing oil cylinder and intermediate plate 33 are hinged, 4 bottom of quick changing oil cylinder and cylinder pedestal
17 is hinged, and guarantees oil cylinder axis and quick change link mechanism in same plane by changing washer 5.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformations can also be made, these improvement and deformations
Also it should be regarded as protection scope of the present invention.
