Problems solved by technology

In the development process of battery-driven excavators, in order not to affect the mobility of the excavator, the power supply method of separating the battery and the excavator is usually used. This power supply method has the disadvantages that the cable is easy to wear when mopping the ground, and the excavator is easy to break when walking. Key problems such as inconvenient cable and cable retraction

Abstract

The invention relates to a cable automatic collecting and releasing system of a pure electric hydraulic excavator, which is mainly composed of an electric power output system and an electric power input system, and is characterized in that the electric power output system is composed of a battery trailer, a two-way plug, a cable collecting and releasing device, an adjustable screw branch device, a tensile cable and the like, and the electric power input system is composed of a cantilever extending device, a hydraulic supporting device, a fixed branch frame and the like; and a battery is installed on the battery trailer, the cable collecting and releasing device is installed above the battery, the tensile cable is wound on the cable collecting and releasing device, the adjustable screw branch device and the fixed branch frame enable the tensile cable to be suspended, the fixed branch frame is installed above the tail end of the cantilever extending device which is fixed on an excavator traveling stand, and the hydraulic supporting device is installed below the tail end of the cantilever extending device.

Description

technical field [0001] The invention relates to the technical field of pure electric excavators, in particular to an automatic cable retracting system for a separate battery-driven excavator. Background technique [0002] With the in-depth development of human modernization and the continuous investment in large-scale engineering projects, as one of the most widely used construction machinery, the types and quantities of excavators continue to increase. The energy consumed and the pollutants emitted by a large number of diesel-powered excavators place an incalculable burden on the environment. Therefore, the development of battery-driven excavators with a wide range of energy sources has become a new trend in the construction machinery industry. In the development process of battery-driven excavators, in order not to affect the mobility of the excavator, the power supply method of separating the battery and the excavator is usually used. This power supply method has the dis...
