Counterweight adjustment device for construction machinery and construction machinery

Abstract

The invention provides a balance weight adjustment device for engineering machinery and the engineering machinery. The balance weight adjustment device comprises a pumping device, a first liquid storage box and a second liquid storage box, wherein the pumping device comprises a hydraulic pump; the first liquid storage box is communicated with the second liquid storage box; a hydraulic loop is formed among the first liquid storage box, the second liquid storage box and the hydraulic pump; the first liquid storage box and the second liquid storage box are mounted at different positions of the machine body of the engineering machinery; the pumping device is controlled to adjust the weight of counterweight liquid in the first liquid storage box and the second liquid storage box so as to adjust the center of gravity of the engineering machinery. According to the invention, when the balance weight adjustment device is mounted in the engineering machinery, the weight of the counterweight liquid in the first liquid storage box and the second liquid storage box is adjusted to more conveniently adjust the balance weight at the first liquid storage box and the second liquid storage box, so that the weight state of the engineering machinery can be effectively improved, the center of gravity of the engineering machinery is adjusted, and the adaptation of the engineering machinery to the working condition is improved.

Description

technical field [0001] The invention relates to the field of counterweight adjustment, and more particularly, relates to a counterweight adjustment device for construction machinery and construction machinery. Background technique [0002] The weight distribution of construction machinery is often different under no-load and full-load conditions. If the paver needs to hang up the screed when the paver is transitioning without load, the center of gravity will move backward, causing the front end to tilt; while during the paving operation, the screed is suspended above the material, and the host does not need to lift the screed weight so that the center of gravity moves forward. [0003] It is such a situation that it is necessary to install an adjustable counterweight on the construction machinery to achieve the effect of balancing the center of gravity.
