The movable hook seat is pivoted to a second end of the main body and is provided with a movable hook. The hydraulic cylinder is combined to the main body and is connected with the movable hook seat. A second pivot pin of the bucket is hooked or released by the movable hook of the movable hook seat under the control of reciprocating motions of a hydraulic cylinder convex rod. Simple actions are not needed being implemented by a complex structure, and thus the utility model has the advantages of cost saving, convenient and safe operation and obvious advanced character.
Description
Technical field
The utility model belongs to a kind of hookup mechanism, particularly a kind of excavator anchor clamps hookup mechanism.
Background technology
With the develop rapidly of work science and technology, will be the society of a diversification future.Yet we can find that everywhere the structural form of society makes rapid progress.The required quality of the life of people improves relatively, and the requirement of things also from the old thinking of " can with all right ", is become quite fine and smooth.Have the conception of continuous progress or innovation only, could satisfy the demand of modern society.
The Taiwan patent gazette that is numbered No. 473582 discloses a kind of " the quick bucket exchanger of excavator ".This bucket exchanger is assembled between the lever arm and scraper bowl of excavator, and this bucket exchanger is articulated with the lever arm end and the vertical connecting rod end of excavator respectively by trunnion.Body root edge one side of this bucket exchanger is provided with fixed hook, and is assembled with in body and can colludes in the activity that the root edge opposite side is done to pivot, and is provided with the control activity again and colludes pivot whether catch bar and fastening plate in body.Like this, can collude if discharges the trunnion of scraper bowl apical margin the purpose of changing bucket with realization by fixed hook with movable.
This anchor clamps hookup mechanism has following shortcoming: the scraper bowl of excavator has suitable weight, change scraper bowl with bucket exchanger commonly used its inconvenient application of force problem is arranged, and the quick bucket exchanger structure of this excavator is various, and manufacturing cost relatively improves and too complicated, and the convenience of operation is lower.In addition, the spring of member also needs to consider the problem that its elasticity scarcity and bearing capacity be whether enough.Under the environment of more and more paying attention to work safety, the designer need strengthen practicality and security consideration.
Summary of the invention
The purpose of this utility model provides a kind of excavator anchor clamps hookup mechanism.This excavator anchor clamps hookup mechanism has not only been simplified the structure of grip device, has also improved practicality and safety simultaneously.
The excavator anchor clamps hookup mechanism of the utility model design includes: a body, and this body combines with the lever arm of excavator, and an end of body is provided with a fixed hook, and fixed hook colludes under the control of lever arm if discharge first trunnion of scraper bowl; Seat is colluded in one activity, and this activity is colluded seat and is articulated in second end of body and has an activity and collude; One hydraulic cylinder, this hydraulic cylinder are incorporated into body and seat is colluded in the connection activity, and the activity that seat is colluded in this activity is colluded under the reciprocating motion of hydraulic cylinder nose bar control and colluded if discharge second trunnion of scraper bowl.
The excavator anchor clamps hookup mechanism of the utility model design has the following advantages:
1, the lever arm of excavator can fix fixed hook one trunnion of scraper bowl, and hydraulic cylinder can collude seat by nose bar drive activity, directly activity is colluded and establish another trunnion that fixes scraper bowl, only need control hydraulic cylinder during changing-over retracts activity and colludes seat and break away from a trunnion and can unload scraper bowl, installation and removal are all quite convenient, and no longer need multiple connector finish the installation and removal action, can save time, manpower and fund cost.
2, the element of placing restrictions on of the present utility model can collude in nose bar promotion activity and the time push the activity of blocking to the location and collude, and swings to avoid activity to collude, and the safety that this simple member promptly can be this anchor clamps hookup mechanism provides safeguard.
Accompanying drawing is described
Below in conjunction with the accompanying drawing illustrated embodiment the utility model is described further.
Fig. 1 is a stereogram of the present utility model.
Fig. 2 is a three-dimensional exploded view of the present utility model.
Fig. 3 connects the state diagram of scraper bowl first trunnion for the utility model.
Fig. 4 finishes figure for the utility model connects scraper bowl.
The specific embodiment
As shown in the figure, 10 is body, and 11 is the lever arm pivoted hole, and 12 is the kelly hole, 13 is pivoted hole, and 131 is pivoting lever, and 14 for placing restrictions on element, 141 stopping bars that exceed, 142 are perforation, and 15 is fixed hook, and 16 is clamping piece, and 17 is draw-in groove, 20 is hydraulic cylinder, and 21 is fastening part, and 22 is nose bar, and 23 is connecting hole, 30 collude seat for activity, and 31 collude for activity, and 32 is pivot hole, and 33 is connecting hole, 34 is connecting rod, and 40 is scraper bowl, and 41 is trunnion.
This excavator anchor clamps hookup mechanism mainly comprises:
One body 10, this body 10 are provided with lever arm pivoted hole 11, kelly hole 12 and the pivot hole 13 that runs through both sides.Lever arm connects hole 11 and is arranged in top, two sides corner, can be for combining with the lever arm end of excavator.Body 11 has first end and second end, and first end of body 10 has a fixed hook 15; The pivot hole 13 of second end wears for a pivoting lever 131.The same side at fixed hook 15 is provided with clamping piece 16 in addition, and this clamping piece 16 is arranged with a draw-in groove 17.This body 10 is provided with one in addition and places restrictions on element 14, is to have the bar of placing restrictions on 141 on the lamellar body, places restrictions on element 14 and can push kelly hole 12;
One hydraulic cylinder 20, this hydraulic cylinder 20 is provided with fastening part 21, makes draw-in groove 17 that hydraulic cylinder 20 is equipped in body 10 to reach the function of pivot pendulum, and an end of hydraulic cylinder 20 has a nose bar 22, nose bar 22 can be done reciprocal motion by hydraulic cylinder 20 controls, is equipped with a connecting hole 23 on the nose bar 22;
One scraper bowl 40, this scraper bowl 40 has two trunnions 41, and the fixed hook 15 of body 10 can directly collude with the lever arm of excavator if discharge trunnion 41, but and movable seat 30 nationalitys that collude are colluded if discharge trunnion 41 by the reciprocating motion of hydraulic cylinder 20 nose bars 22.
As shown in Figure 3 and Figure 4, excavator anchor clamps linkage is colluding when putting scraper bowl 40, and the fixed hook 15 of linkage colludes first trunnion 41 of establishing scraper bowl 40 apical margins earlier.Collude establish fixing after, hydraulic cylinder 20 is released nose bars 22 and is colluded seat 30 to promote activity, the activity that seat 30 is colluded in this activity is colluded 31 and is advanced and collude second trunnion 41 of establishing scraper bowl 41 apical margins at the thrust lower edge of nose bar 22 camber line.When 31 to one halted states are colluded in nose bar 22 promotion activities, push and place restrictions on element 14 and collude 31 to block activity, scraper bowl 40 is promptly stable to be fixed on the anchor clamps linkage.These anchor clamps linkage is finished to collude by the reciprocating motion of hydraulic cylinder 20 nose bars 22 and is established, and simplifies the structure, reduced cost greatly, has improved safety, has obvious progress.
