Movable balance weight

Abstract

The invention discloses a movable balance weight which comprises a base, a bracket, a balance weight body, a left-right movement oil cylinder and an overturning oil cylinder, wherein the left-right movement oil cylinder is mounted on the base, one end of the left-right movement oil cylinder stretches out of the base and is fixed on the bracket, the bracket is fixed on the base and can slide on the base, the balance weight body is mounted on the bracket, an overturning oil cylinder groove is formed in the balance weight body, the overturning oil cylinder is mounted in the overturning oil cylinder groove, the lower end of the overturning oil cylinder is hinged to the bracket, the upper end of the overturning oil cylinder is hinged to the balance weight body, and the balance weight body rotates around a rotary shaft on the balance weight body under the driving of the overturning oil cylinder. The movable balance weight can move leftwards and rightwards and turn over backwards to enable the gravity center of the balance weight to move backwards so that the weight of the balance weight can be reduced under the same load condition, the structure is simple, and the balance weight is convenient to manufacture and maintain.

Description

technical field [0001] The invention relates to a counterweight, in particular to a mobile counterweight. Background technique [0002] The counterweight is a part used for automobiles, cranes or heavy-duty loading vehicles. In the existing counterweight products, the counterweight is immovable, or the movement direction is single, and the counterweight weight designed for its maximum load, in normal times Generally, there is a large margin during operation, and the whole machine is heavy, which will also increase economic costs such as fuel consumption during operation. If some heavy objects are hung outside the car, crane or heavy loading vehicle, the original design load will be destroyed, causing dangers such as tilting or overturning of the car, crane or heavy loading vehicle. Contents of the invention [0003] The purpose of the invention of this application is to improve the stability of engineering machinery such as cranes and excavators when operating in complex ...
