Abstract

A series ball joint multi-degree-of-freedom controllable electric mechanism excavator, including a frame, a boom, a telescopic boom, a small arm and a bucket, the specific structure and connection relationship are: the boom is hinged on the On the fuselage of the frame, the telescopic support plate of the telescopic arm is arranged at the front end of the boom, and is fixedly connected with the boom, and the bucket is hinged with the small arm through a bucket pin. The invention adopts the electric push cylinder as the main power source of the mechanical arm, that is, it only needs to control the electric push cylinder to complete the complex spatial trajectory movement, and improves the operability and reliability of the machine in complex environments.

Description

technical field [0001] The invention relates to a heavy-duty construction machine, in particular to an excavator with a multi-degree-of-freedom controllable electric mechanism of a serial ball joint. Background technique [0002] An excavator is an earth-moving machine that uses a bucket to excavate materials above or below the bearing surface, and loads them into transport vehicles or unloads them into stockyards. Among them, the hydraulic excavator is a type of excavator widely used, but the cost of the hydraulic system is high, oil leakage is prone to occur, and it cannot work normally in extreme environments, such as extreme cold or high temperature environments, the properties of hydraulic oil will change accordingly , so that the mechanical performance is reduced or even unable to work, which is a long-standing thorny problem of hydraulic excavators. However, the traditional single-degree-of-freedom mechanical excavator, commonly known as "electric shovel", can only r...
