Abstract

This application relates to the technical field of engineering vehicles, and in particular to a gap adjusting pad assembly and an excavator. The gap adjusting pad assembly includes: a first pad main body, a second pad main body and an elastic support member; a first pad The tray main body is arranged opposite to the second dolly main body, and the elastic supporting member is arranged between the first dolly main body and the second dolly main body. The gap adjustment pad assembly provided by this application can be easily and conveniently installed between the bucket and the arm, and can undertake the work of filling the gap for a long time, with a low probability of damage, avoiding the need to stop the excavator for maintenance, replace gaskets or wear-resistant plates , affecting the construction progress.

Description

technical field [0001] The present application relates to the technical field of engineering vehicles, in particular to a gap adjusting pad assembly and an excavator. Background technique [0002] The bucket and arm of a large backhoe excavator are connected through a pin shaft. After a long period of wear, a gap will appear between the matching position between the bucket and the arm, which will cause the bucket to shake and affect the normal operation of the excavator. Install the wear ring to solve this problem. If the gasket is not added in time, it will also cause damage to the joint of the bucket and the stick. Even if the gasket or wear ring is installed for a long time, the bucket still needs to be disassembled It is inconvenient to reinstall, disassemble and maintain, and the gasket or wear ring will also cause damage to the clearance fit between the bucket and the arm during the process of bearing wear. Contents of the invention [0003] The purpose of this appl...
