Description
Technical field
The utility model relates to loading machine technical fields, more particularly to a kind of loading machine quick-change carrier structure.
Background technique
Loading machine plays irreplaceable role as the high representative unloaded of shovel dress in engineering machinery.Working condition is not
Together, it needs dedicated accessory system to work, can be only achieved the effect got twice the result with half the effort.Some of them operating condition had both needed scraper bowl class
Accessory is excavated, and needs promptly class accessory crawl, and high frequency of replacement.Since the movement of accessory and link mechanism is
The gap of through hole and pin shaft with realize, in addition accessory weight be tonne, replacement accessory need profession lifting, for user
It is unrealistic.
Therefore, a kind of manipulator's shank type accessory replacement bracket comes into being.Current quick change bracket is varied, but it is former to work
It manages similar.Each three or four hinge joints, front end are coupled with accessory hinge joint before and after bracket, and rear end and link mechanism are cut with scissors
Contact is coupled, and active force is transmitted according to " link mechanism-bracket-accessory " route.
Current common quick change bracket is front and back hinge joint form, structure chart such as attached drawing 1.It is by hinge joint 1, hinge joint
2, hinge joint 3 and hinge joint 4 form.The fast replacing device installs construction profile figure after scraper bowl, sees Fig. 2, the following institute of working principle
It states.
1) bracket needs profession lifting to be installed in place (hydraulic system does not embody in figure) with link mechanism in advance；
2) the compound control crank of driver makes bracket hinge joint 3 and scraper bowl upper hook complete hanging scroll；
3) swing arm is promoted in right amount and receives bucket, keeps scraper bowl lower link point and bracket hinge joint 2 coaxial；
4) manipulation bracket cylinder is assembled to pin shaft in the coaxial aperture of step 3 completion.
Currently common quick change bracket has the following disadvantages:
1) accessory and bracket hinge joint (hinge joint 2) and link mechanism and bracket (hinge joint 1) do not share hinge joint, equally
In the case of bucket shape and link mechanism, relative to complete machine front overhang it is larger (rated load reduce, sticked up power reduce, discharge height compared with
It is small).
2) in the course of work, active force is transmitted according to " link mechanism-bracket-accessory " route, therefore strong to carrier structure
Spend more demanding (increased costs).
In conclusion in the prior art for the Quick universal problem of loading machine bracket, still shortage effective solution scheme.
Utility model content
In order to solve the deficiencies in the prior art, the utility model provides a kind of loading machine quick-change carrier structure, has
It improves discharge height, reduce manufacturing cost, effect easy to operate.
A kind of loading machine quick-change carrier structure, including accessory, quick change bracket and link mechanism, the accessory surface are equipped with the
One hook and the second hook, the quick change bracket include baffle, pin shaft support frame, pin shaft socket, hydraulic cylinder, swing arm axis and drawing
Bar axis, the baffle be equipped with it is multiple, welded together between multiple baffles by steel plate, details are not described herein；Baffle generally takes
Four, every two baffle forms a baffle plate assembly, and two baffle tops for forming baffle plate assembly are equipped with axis hole, and lower part is equipped with pin
Socket axis, lower part are additionally provided with hydraulic cylinder pedestal.
Further, the quantity of pin shaft support frame and the quantity of baffle plate assembly are identical, and pin shaft support frame is rectangular plate, institute
It states pin shaft support frame to set there are three through-hole, the through-hole at middle part passes through the hole on the hinged baffle top of pin shaft, and the through-hole at rear portion passes through pin
The hinged hydraulic cylinder of axis, hydraulic cylinder connect the through-hole and oil cylinder pedestal at rear portion.
Further, the hole grafting pull rod shaft of the front of the pin shaft support frame.
Further, the pin shaft socket and swing arm axis are mating.
