Abstract

The invention provides an engineering machine and a balance weight adjusting device thereof. The balance weight adjusting device comprises a first telescoping cylinder and second telescoping cylinders, wherein the first telescoping cylinder comprises a drive fluid accommodating cavity and a balance weight liquid accommodating cavity; each second telescoping cylinder comprises a drive fluid accommodating cavity and a balance weight liquid accommodating cavity, and the balance weight accommodating cavity of the second telescoping cylinder is communicated with the balance weight liquid accommodating cavity of the first telescoping cylinder; and weights of the first telescoping cylinder and the second telescoping cylinders are adjusted by adjusting proportions of the balance weight liquids in the first telescoping cylinder and the second telescoping cylinders. The balance weight adjusting device is simple in structure and convenient to operate, and can be conveniently mounted in the engineering machine whose balance weight is required to be adjusted; after the balance weight adjusting device is mounted in the engineering machine, the weight distribution state of the engineering machine can be effectively improved by adjusting the proportions of the balance weight liquids in the first telescoping cylinder and the second telescoping cylinders, and the adaptive capacity of the engineering machine to the working condition is improved.

Description

technical field [0001] The invention relates to the field of counterweight adjustment, and more particularly relates to an engineering machine and a counterweight adjustment device thereof. Background technique [0002] The weight distribution of construction machinery is often different under different working 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. It is such a situation that it is necessary to add weights to the construction machinery to achieve a balanced effect. Contents of the invention [0003] The purpose of the present invention is to provide a construction machine and a counterweight adjusting device thereof, so as to solve the problem that the counterweight...
