The invention relates to the technical field of machine manufacturing, and discloses an automatic counterweight adjusting device for hoisting machinery, which comprises a bearing mechanism, a hoisting mechanism for hoisting heavy objects is arranged at the upper end of the bearing mechanism, a first driving mechanism for driving the hoisting mechanism to operate is arranged on one side of the hoisting mechanism, and a second driving mechanism for driving the hoisting mechanism to operate is arranged on the other side of the hoisting mechanism. An air pressure mechanism used for generating downward pressure is arranged on one side of the lifting mechanism, expansion mechanisms used for driving the air pressure mechanism to move are arranged on the lower portions of the two sides of the lifting mechanism, and second driving mechanisms used for driving the two expansion mechanisms to operate are fixedly connected to the upper ends of the two expansion mechanisms. And when the second driving mechanism drives the two expansion mechanisms to move synchronously or differentially, the position of the wind pressure mechanism is changed, and the downward pressure generated by the wind pressure mechanism is correspondingly adjusted, so that dynamic counterweight adjustment of the hoisted heavy object is realized.

    本发明涉及机械制造技术领域,公开了一种起重机械用自动配重调节装置,包括承托机构,所述承托机构上端设置有用于起吊重物的起吊机构,所述起吊机构一侧设置有用于带动起吊机构运转的第一驱动机构,所述起吊机构一侧设置有用于产生下压力的风压机构,所述起吊机构两侧靠下处均设置有用于带动风压机构移动的拓展机构,两个所述拓展机构上端固定连接有用于带动两个拓展机构运转的第二驱动机构,通过杠杆原理的运用,实现了对风压机构施加力的有效放大,当第二驱动机构驱动两个拓展机构同步或差异化移动时,风压机构的位置随之改变,其产生的下压力也相应调整,从而实现了对起吊重物的动态配重调节。
