Abstract
A kind of big arm of digger for installing damping device.Large arm is divided into front and rear two sections by it, and attachment means are designed in junction before and after large arm, and attachment means respectively install two groups of Rubber shock-absorbing pads up and down.In work progress, when vibrations pass to excavator base machine by large arm, Rubber shock-absorbing pad can largely filter vibrations.
Description
Technical field
Mitigate the present invention relates to one kind and even avoid excavator front end such as scraper bowl, quartering hammer, ridge buster in work progress
Constructing device and rock etc. excavate the device that the vibrations produced during object contact are delivered to vehicle body by large arm, especially work as excavation
When the rock crushing tool work such as machine equipment quartering hammer, rock arm.
Background technology
The vibrations produced when being engaged in ordinary excavating work due to existing excavator are not easy to cause excavator base machine damage,
So the excavator that in the market is bought does not equip shock absorbing apparatus.But in recent years, the examination ＆ approval day due to China to explosion
Benefit is harsh, and the financial cost of explosion and environmentally friendly cost suddenly increase, and causes all kinds of excavators repacking arm blowouts to increase, they
The vibrations produced in work progress are very big, such as the continuous vibration that is produced when quartering hammer and rock contact, utilize forearm weight
Strenuous vibration produced during the loosening device shock rock that inertia is excavated etc..Existing excavator bears this kind of vibrations for a long time, right
The many structural member damages of fuselage are very big, directly result in excavator service life and significantly shorten, Frequent Troubles.Nevertheless, comparing
In the sky high cost of explosion, this form of construction work still cost performance that explosion is reduced to sacrifice excavator service life is quite high.
The content of the invention
In order to reduce damage of the vibrations to excavator base machine of fore device generation when some repacking arms of excavator equipment work
Wound, the present invention provides a kind of big arm of digger for installing damping device, and the new large arm can effectively filter excavator fore device
The vibrations operationally produced, damage when mitigating the work of excavator equipment maintenance man-hour expense arm to reach to fuselage, extension excavator makes
With the life-span, the purpose of failure is reduced.
The technical solution adopted for the present invention to solve the technical problems is：Large arm is divided into front and rear two sections, in front and rear connection
Place's design attachment means, such as pin connection, snap connection, silk mouthful connection, attachment means respectively install two groups of Rubber shock-absorbing pads up and down.
In work progress, when vibrations pass to excavator base machine by large arm, Rubber shock-absorbing pad can largely filter vibrations.
The beneficial effects of the invention are as follows can effectively filter vibrations when excavator equipment maintenance man-hour expense arm works, reduce fuselage
Damage, extends excavator service life, reduces failure.
