The invention discloses a falling-off type counterweight device, a mounting and falling-off method and a tower crane, the counterweight device comprises a plurality of counterweights, each counterweight comprises a main steel plate, a mounting groove and/or a supporting device are/is arranged on the side face of the bottom end of each main steel plate, and limiting devices are arranged on the front end face and the rear end face of each main steel plate; the main body steel plates of the plurality of counterweights are connected in sequence, and the heights of the bottom surfaces of the plurality of main body steel plates are not in the same plane and are increased or decreased in sequence; the mounting groove of the main steel plate with the lower bottom surface is clamped on the supporting device on the main steel plate with the higher bottom surface, and the supporting device on the main steel plate with the higher bottom surface is arranged in a sliding manner along the mounting groove of the main steel plate with the lower bottom surface; and the limiting device is used for preventing the positions of the plurality of main steel plates in the counterweight device from deviating. According to the counterweight device designed by the invention, a plurality of counterweights fall to the ground one by one, and the impact on the ground is reduced.
本发明公开了本申请一种可脱落式平衡重装置、安装脱落方法及塔式起重机,平衡重装置包括多块平衡重,平衡重包括主体钢板,主体钢板底端的侧面设有安装槽和/或支撑装置,主体钢板的前后端面均设有限位装置;多块平衡重的主体钢板依次连接,多块主体钢板的底面的高度不在同一平面内,且多块主体钢板的底面的高度依次增加或减小;底面高度低的主体钢板的安装槽卡合在底面高度高的主体钢板上的支撑装置上,且底面高度高的主体钢板上的支撑装置沿底面高度低的主体钢板的安装槽滑动设置;限位装置用于防止平衡重装置中的多块主体钢板位置发生偏移。本申请设计的平衡重装置,实现多块平衡重的逐块落地,减小了对地面的冲击。
