Engineering mechanical equipment, movable counterweight system and control method

Abstract

The invention relates to a movable counterweight system used for engineering mechanical equipment, which comprises a counterweight, an information acquisition device, a computation module, a control module and an adjusting device, wherein the information acquisition device is used for acquiring working state information of the engineering mechanical equipment; the characteristic parameter information of the engineering mechanical equipment is stored in the computation module in advance, and the computation module computes the ideal counterweight position of the counterweight according to the working state information and the characteristic parameter information; the control module compares the ideal counterweight position with the practical counterweight position of the counterweight and outputs control signal; and the adjusting device receives the control signal output by the control module, and adjusts the counterweight to the ideal counterweight position. The invention further provides engineering mechanical equipment and a movable counterweight control method. Through the engineering mechanical equipment, the movable counterweight system and the control method, the adjustment of counterweight position can be realized, and the working stability and safety of the engineering mechanical equipment are improved.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an engineering machinery equipment, a movable counterweight system and a control method. Background technique [0002] Some construction machinery equipment (such as cranes, excavators, etc.) are often equipped with counterweights, which can make the center of gravity of the construction machinery equipment as close as possible to the center of rotation of the car body, so as to ensure the dynamic stability of the car body and reduce the impact of the slewing support. Turn resistance, and achieve a fast and smooth turn. Taking an excavator as an example, in order to ensure the normal operation of the excavator, the stability and safety of the excavator need to be considered in the design and layout of the excavator's counterweight. Improper consideration of the stability and safety of the excavator can cause the excavator to shake seriously or even roll over during...

AI Technical Summary

Problems solved by technology

However, as the working radius increases, the working device of the excavator will generate a considerable overturning moment, which will greatly reduce the stability and safety of the excavator

Moreover, during the excavation process, inertial loads, changes in operating objects, and external sudden loads are unavoidable. If the stability performance range that can be achieved by the fixed counterweight is exceeded, the excavator will shake, and even roll over in severe cases.

Due to the loss of stability of the whole excavator, the excavator cannot fully exert its digging force, which will cause waste of resources and irreparable losses
