Brief description of the drawings
Fig. 1 is the front section view of the utility model；
Fig. 2 is the stereogram of the utility model.
Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Excavator may need replacing different accessories, such as scraper bowl, ridge buster, quartering hammer in different workplaces
Deng this just needs quick change adapter connector to carry out quick-replaceable to different accessory.
Shown in Fig. 1 to Fig. 2, a kind of excavator quick change adapter connector, including left plate 1, right plate 2, left plate 1 and right plate
Matched with excavator boom (not shown) preceding axis pin 3 and rear pin shaft 4 are inserted between 2 top, between middle and lower part
Hook plate 6 before being provided with oil cylinder 5 and being hinged with one piece, preceding hook plate 6 are driven by oil cylinder 5, and the lower part of the preceding hook plate 6 is equipped with and digging
The preceding hook portion 61 that pick machine accessory (not shown) fastens, is provided with and excavates between left plate 1 and the middle and lower part of right plate 2
The rear hook portion 7 that machine accessory fastens, preceding hook plate 6 may be rotated under the driving of oil cylinder 5, so that hook portion before further driving
61 engagings depart from accessory, so as to complete the replacement to accessory.
The left plate 1 includes upper left side plate 1a, left side plate 1b and the lower side that 2 direction of side plate overlaps successively to the right
1c, the right plate 2 includes upper right side plate 2a, right latus inframedium 2b and the bottom right side plate 2c that 1 direction of side plate overlaps successively to the left, left
The lap-joint of epipleural 1a, left side plate 1b and lower side 1c end faces are equipped with one piece of left reinforcement block 8 in zigzag, upper right side
The lap-joint of plate 2a, right latus inframedium 2b and bottom right side plate 2c end faces are equipped with one piece of right reinforcement block 9 in zigzag, above-mentioned overlap joint
Direction is the interior direction overlap joint to quick change adapter connector, i.e., each block of side plate on left plate 1 and right plate 2 is from top to bottom gradually
Close, the set-up mode of this left plate 1 and right plate 2 makes quick change adapter connector compact-sized, and will not making inside, there are larger
Gap, and do not have to take the measure for being welded with other steel plates or installing other structures additional in inside to make compact-sized again.
Because needing relatively wide distance between 2 top of width requirement left plate 1 and right plate of dipper, and oil cylinder 5 with
And preceding hook plate 6 is not required for having relatively wide distance between the middle and lower part of left plate 1 and right plate 2；
So if wide if the upper, middle and lower portion between left plate 1 and right plate 2, left plate 1 and right plate 2 can be made
Middle and lower part exist very big gap, structure is not compact enough, in this case, since the working environment of excavator is quite multiple
Miscellaneous, the presence in gap can make soil, rubble, dust directly hit, contact to generations such as oil cylinder 5, preceding hook plate 6, fluid pressure lines
Large effect；And if take the mode solution of left plate 1 and right plate 2 steel plate itself not uniform thickness (such as middle and lower part is welded with steel plate)
Certainly, it can also increase cost and make quick change adapter connector heavier, so 1 He of left plate can be made by the way of overlap joint
Right plate 2 will not increase extra weight in each position uniform thickness, and can make to produce upper width between left plate 1 and right plate 2
Under narrow cramped construction.
The setting of left reinforcement block 8 and right reinforcement block 9 further increases the intensity of left plate 1 and right plate 2.
One piece of upper cover plate 10 for being located at preceding 6 top of hook plate, lower side are equipped between upper left side plate 1a and upper right side plate 2a
One piece of side cover plate 11 for being located at 5 side of oil cylinder is equipped between 1c and bottom right side plate 2c, is as previously mentioned, the building ring of excavator
Border is considerably complicated, and the inside that soil, rubble, dust etc. can all enter quick change adapter connector has an impact, so upper cover plate 10 and side
The setting of cover board 11 can further play protective action.
A safety pin that preceding hook plate 6 can be prevented to be separated with accessory is equipped between upper left side plate 1a and upper right side plate 2a
12, safety pin 12 carries out the spacing of direction of rotation counterclockwise to the top of preceding hook plate 6, its mode of action is：Current hook plate 6 exists
Under the driving effect of oil cylinder 5, after preceding hook portion 61 engages with accessory, still it is likely to occur in the course of work, the preceding loose hook of hook portion 61
Risk, is at this time inserted into a safety pin 12, it is possible to which hook plate 6 rotates loose hook before preventing.
Left side plate 1b and right latus inframedium 2b is equipped with put when being pulled down for safety pin 12 concentric and puts in order hole 12a,
Since excavator working site environment is complicated, after replacement accessory pulls up safety pin 12, put in order if none of fixed
Position, it is easy to lose, quick change adapter connector loses one of insurance after loss, very troublesome, is set for this on quick change adapter connector
Hole 12a is put in order, prevents from losing.
It is furnished with hydraulic control one-way valve 51 on oil cylinder 5, further prevents that hook plate 6 produces rotation before making due to the possible contraction of oil cylinder 5
Turn the phenomenon of loose hook.
Upper left side plate 1a and upper right side plate 2a is equipped with arc reinforcing plate 13 close to the position of rear pin shaft 4, further strengthens
The intensity of left plate 1 and right plate 2 at rear pin shaft 4.
Upper cover plate 10 is equipped with a hangers 14, conveniently carries, transports whole quick change adapter connector.
It the above is only the utility model preferred embodiment, those skilled in the art is made equivalent change by claim
Both fall within the protection domain of this case.
