Background technology
At present, the equipment annex fast replacing device that domestic hydraulic crawler excavator is equipped with has two kinds of structures of mechanical type and fluid pressure type, when mechanical structure is changed the equipment annex the user, need handle the replacement of the mechanical mechanism realization equipment of quick change with manpower; The fast replacing device of fluid pressure type structure can be realized changing equipment by the manipulation of hydraulic pressure, but when at present all having safety pin on the fast replacing device of fluid pressure type structure and being used for preventing hydraulic system fails security incident takes place, so the fast replacing device of this kind fluid pressure type structure can not be realized handling without manpower fully.
Summary of the invention
The purpose of this utility model is to provide the hinged bucket arm cylinder of a kind of dipper, rocking bar and connecting rod, is connected with the hydraulic pressure fast replacing device between dipper and the equipment annex.There is sliding tray the pedestal inboard, on the quick change dead bolt sliding closure is arranged.Assembling on two pin shaft holes of equipment annex (or welding) has two bearing pins.Can lock by automation, realize changing fast the hydraulic pressure quick-changing mechanism of equipment annex fully by hydraulic operation.
Operating principle of the present utility model is such, by operating hydraulically operated oil cylinder, can realize the locking and the opening action of quick change dead bolt.When operating hydraulically operated cylinder is realized the opening action of quick change dead bolt, the pressure that requires hydraulic cylinder to produce can overcome the thrust that spring produces, when operating hydraulically operated cylinder is realized the locking action of quick change dead bolt, the thrust direction of the thrust that hydraulic cylinder produces and the generation of spring is consistent, thereby guarantee when hydraulic system is not worked or lost efficacy, the quick change dead bolt still can be in locking state under the effect of spring force, guarantee that the equipment annex can accident not come off.Hydraulic control component and pipeline comprise the hydraulic control one-way valve that connects the fast replacing device oil cylinder, 26 three-way electromagnetic valves and corresponding joint and pipeline.Its hydraulic control principle is as follows: 26 three-way electromagnetic valve inlets insert the revolution working oil path, 26 three-way electromagnetic valves export one the road and insert hydraulic control one-way valve, insert quick change oil cylinder rodless cavity oil circuit from hydraulic control one-way valve, 26 three-way electromagnetic valves export other one the road and insert quick change cylinder rod chamber oil circuit.The hydraulic pressure fast replacing device is when no matter 26 three-way electromagnetic valves are in " opening " or " locking " at button, and " dead bolt " of fast replacing device is in a state that stretches out all the time, prevents that the scraper bowl accident from dropping.Have only when button is positioned at the position of " opening ", after the guide operated to revolution, dead bolt was just withdrawn in the hydraulic quick coupler, and this moment, the equipment annex can unload.Hydraulic control one-way valve plays the dual security protection effect to fast replacing device simultaneously.
Technical solution of the present utility model is such, comprise dipper, hydraulic pressure fast replacing device, equipment annex, hydraulic control component and pipeline, it is characterized in that the hinged bucket arm cylinder of dipper, rocking bar and connecting rod, be connected with the hydraulic pressure fast replacing device between dipper and the equipment annex, equipment annex and fast replacing device have quick change pedestal, quick change dead bolt and working body are arranged.
The inboard of quick change pedestal is milled with sliding tray, is milled with sliding closure on the quick change dead bolt.
Working body is equipped with equipment annex bearing pin I, equipment annex bearing pin II.
26 three-way electromagnetic valve buttons of hydraulic pressure fast replacing device are in to be opened and/or locks, and the dead bolt of hydraulic pressure fast replacing device is in the state that stretches out, and when button is in the position of opening, the guide is lever operated, and dead bolt is just withdrawn in the hydraulic quick coupler, and the equipment annex unloads.
The utility model advantage compared with prior art is to adopt the equipment annex hydraulic pressure fast replacing device of technique scheme, fast quick-detach of equipment annex and installation that the excavator driver only needs in driver's cabin the manipulation by handle and button just can realize.This structure has the triple protection function simultaneously, guarantees that the equipment annex can accident not come off under any state.The hydraulic control component that the utility model increased is technology maturation, the part of mass production, can use homemade supporting, also can use import supporting, so the utility model is a kind ofly easily fast to change the equipment annex, and efficient height, equipment annex hydraulic pressure fast replacing device safe and reliable, simple to operate, easily manufactured, with low cost.
