Description

Technical Field

[0001] The utility model relates to the technical field of anti-vibration mechanisms, in particular to an anti-vibration mechanism for a large excavator platform. Background Art

[0002] Generally, the working environment of the excavator platform is relatively harsh. In such harsh working environment, the vibration of the cab will affect the driving comfort of the operator and accelerate the fatigue of the operator. Therefore, with the widespread use of excavators, the operating comfort of the excavator has received more and more attention. Therefore, the vibration reduction mechanism of the cab is also particularly important, and the vibration reduction mechanism is mainly composed of springs and dampers.

[0003] The existing excavator platform cab usually uses a vibration reduction mechanism installed at the bottom of the cab to reduce vibration. The vibration reduction effect of the vibration reduction mechanism varies under the influence of the damper and the spring. After the vibration reduction mechanism has been used for a period of time, the restoring capacity of the spring and the damper will be worn, resulting in poor vibration reduction effect. It is not convenient to adjust the vibration reduction effect of the vibration reduction mechanism according to the use requirements. Utility Model Content
