Movable arm deceleration control device and method of excavator and excavator

Abstract

The invention provides a movable arm deceleration control device and method of an excavator and the excavator, and relates to the technical field of engineering machinery. The movable arm decelerationcontrol device comprises a controller, a movable arm driving module, and an angle displacement acquirer arranged on a working device of the excavator; the angle displacement acquirer is connected with the controller; the controller is connected with the movable arm driving module; the angle displacement acquirer is used for acquiring angle displacement information of the working device in the descending process and sending the angle displacement information to the controller; the controller is used for obtaining working state information of the working device according to the angle displacement information and sending control signals to the movable arm driving module when the working state information reaches a preset state; and the movable arm driving module is used for adjusting the movable arm descending speed of the working device according to the control signals. The movable arm deceleration control device can control the movable arm descending speed of the working device in thedescending process to prevent potential safety hazards caused by overspeed.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an excavator boom speed reduction control device and method and the excavator. Background technique [0002] Construction machinery, especially large-scale excavator equipment, its working device includes boom and arm. When the working device is lowered, due to its own weight, the lowering speed is difficult to control, and it is easy to overspeed, resulting in the occurrence of the working device hitting the ground, Safety problems such as body imbalance or even tipping over. [0003] At present, excavators generally use a hydraulic control system, and the actions of the working devices are all controlled by the operator, which has a lot to do with their personal control ability. Therefore, the control safety of the working devices cannot be guaranteed. In addition, due to factors such as operator fatigue and operational errors, potential safety hazards caused by ...
