Balance weight assembly and excavator

Abstract

The invention discloses a balance weight assembly and an excavator and relates to the technical field of excavator machinery. The balance weight assembly comprises a first balance weight part, a balance weight support seat, support components and a second balance weight part. The balance weight support seat is arranged on the side, away from a excavator platform. The first balance weight part is arranged on the balance weight support seat. The support components are arranged on the side, away from the first balance weight part, of the balance weight support seat. The second balance weight partis connected to the side, away from the balance weight support seat in a detachable manner. The excavator comprises the balance weight assembly. By means of the balance weight assembly, the balance weight total mass of the excavator can be conveniently adjusted through the balance weight assembly, so that the requirements multiple types of working condition can be met.

Description

technical field [0001] The invention relates to the technical field of excavating machinery, in particular to a counterweight assembly and an excavator. Background technique [0002] An excavator is a multi-purpose earth-rock construction machine that uses a bucket to excavate materials above or below the bearing surface and load them into transport vehicles or unload them into stockyards. Excavator excavation is mainly used for earthwork excavation and loading, and can also perform land leveling, slope repair, hoisting and other operations. It has been widely used in the construction of various engineering facilities and has become one of the most important construction machinery in engineering construction. [0003] In order to maintain the balance of the whole vehicle, the excavator is equipped with a counterweight at the tail. The standard type of excavator in the prior art, in the case of the same bucket capacity, the loads on materials with different densities are sev...

AI Technical Summary

Problems solved by technology

When the excavator needs to load low-density materials or run empty, the excess counterweight quality causes a lot of energy waste and increases fuel consumption; when the excavator needs to load high-density materials, the counterweight quality cannot meet the weight of the loaded materials demand, resulting in poor job stability and even the risk of tipping over

Since the structure and weight of the counterweight assembly have been fixed, if the excavator needs to adjust the counterweight quality, it needs to be replaced with a new counterweight.
