Problems solved by technology

During the working process, the bolt 002 is not only subjected to the radial force of the rotation of the pin shaft 300, but also the axial force of the left and right movement of the pin shaft 300, and the bolt 002 is prone to failures such as wear, loosening, breaking or falling off, which will cause the overall damage of the excavator. Abnormal force

Abstract

The invention provides a rocking bar assembling component and an excavator, and relates to the technical field of engineering machinery. The rocking bar assembling component provided by the inventioncomprises a first rocking bar, a second rocking bar, a pin roll, a connecting assembly, a first locking assembly and a second locking assembly, wherein the first rocking bar and the second rocking barare separately arranged at the two sides of the connecting assembly; the pin roll penetrates through the first rocking bar, the connecting assembly and the second rocking bar; the first locking assembly is separately connected to the first rocking bar through a pin roll; and the second locking assembly is connected to the end part, close to the second rocking bar, of the pin roll, and abuts against the second rocking bar. The rocking bar assembling component provided by the invention relieves the technical problem that a bolt for limiting the pin roll is easily worn in the prior art.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a rocker assembly assembly and an excavator. Background technique [0002] Excavator is one of the main types of construction machinery. Its working device can perform functions such as excavation, loading, dismantling, lifting, grabbing, piling, drilling and bulldozing. With its remarkable features such as fast, efficient, flexible and convenient, In recent years, it has been widely used in construction industries such as industrial facilities, civil buildings, road and bridge construction, and national defense construction. The rocker 001 has certain particularity as a part of the working device. It is divided into left and right rockers, which are respectively assembled on the outer end faces of the two sides of the connecting rod 410 and the stick 420, which requires passing through two The pin shaft 300 of the rocking bar 001 has two end face constraints to e...
