The invention relates to the technical field of mechanical parts, and discloses a counterweight device for construction machinery. The device comprises a mounting plate, a counterweight box is fixedly connected to the right side of the mounting plate, a rectangular opening is formed at one side of the counterweight box, a counterweight block is connected in the rectangular opening, and two support frames are fixedly connected to one side of the mounting plate. The opposite sides of the two supporting frames are jointly connected with a supporting mechanism, a bearing plate is transversely arranged at one side of the mounting plate, the side wall of the bearing plate is connected with the supporting mechanism, two strip-shaped mounting holes are symmetrically formed in the side wall of the mounting plate, and hydraulic cylinders are obliquely arranged in the two strip-shaped mounting holes. According to the counterweight device for the construction machinery, the position of a counterweight body of the construction machinery can be effectively adjusted, an externally-assembled balancing weight is convenient to assemble and high in speed, the gravity center of the construction machinery can be effectively lowered through the externally-assembled balancing weight, and the safety of the construction machinery during working is improved.

    本发明涉及机械配件技术领域,且公开了一种用于建筑机械的配重装置,包括安装板,安装板的右侧固定连接有配重箱,配重箱的一侧设有矩形开口,矩形开口内连接有配重块,安装板的一侧固定连接有两个支撑架,两个支撑架相对的一侧共同连接有支撑机构,安装板的一侧横向设有承重板,承重板的侧壁与支撑机构连接,安装板的侧壁对称开设有两个条形安装孔,两个条形安装孔内均倾斜设有液压缸。该用于建筑机械的配重装置,可以有效调整建筑机械自有配重体的位置,并且外装配重块装配方便速度也快,还可以利用外装配重块有效降低建筑机械的重心,增加建筑机械工作时的安全性。
