Description

Technical Field

[0001] The invention relates to the technical field of excavator bases, in particular to an assembled base for an excavator. Background Art

[0002] The excavator base is also called "excavator support seat", "excavator support ring", "excavator connecting seat", "slewing support seat", etc. It is a key structural component that connects the excavator to the vehicle and gets off. The outer ring of the slewing support and the quality of the excavator support seat directly affect the safety and life of the excavator. Therefore, the excavator support seat is a relatively important structural component. The slewing support is an important part of the overall stability of the excavator. During the operation, the excavator needs to constantly move its position to perform operations such as excavation and loading. In this process, the slewing support bears a huge load, including the excavator's own weight, workload, and various forces and torques generated during operation. The slewing support can ensure that the excavator can remain stable under various working conditions to prevent overturning or instability.

[0003] The existing excavator base needs to be docked with a crane and screwed one by one for installation during installation. This installation method requires the use of external tools for installation and docking, which is troublesome, very inconvenient and slow. In addition, the base is prone to tilting when splicing, and it is more laborious to install. In addition, the existing excavator assembled base is more troublesome when installing and docking, because the base is relatively heavy and requires a crane for docking. Therefore, the lifted base needs to be aligned during docking, and then docking is more time-consuming and laborious.
