The additional balance weight support comprises a truss structure, a variable-amplitude pulley block and a pulling plate set, the variable-amplitude pulley block is installed on the top side of the tail of a rotary table, and the truss structure is installed on the tail of the rotary table, connected with the variable-amplitude pulley block through the pulling plate set and used for bearing variable-amplitude force through the pulling plate set in the variable-amplitude process. And the variable-amplitude force arm is increased. The number of the pulling plate sets is two, one end of each pulling plate set is hinged to the variable-amplitude pulley set, and the other end of each pulling plate set is hinged to the truss structure. The pulling plate group comprises a head section of pulling plate, a middle section of pulling plate and a tail section of pulling plate which are hinged, the other end of the head section of pulling plate is hinged with the truss structure, and the other end of the tail section of pulling plate is hinged with the variable-amplitude pulley block. According to the additional counterweight bracket and the crawler crane, the pulling plate group is additionally arranged to connect the truss structure with the variable-amplitude pulley block, so that the variable-amplitude force can be borne by the pulling plate group in the variable-amplitude process, the variable-amplitude force arm is increased, and the overall hoisting effect is improved.
本发明公开了一种附加配重支架,包括桁架结构、变幅滑轮组和拉板组,其中,所述变幅滑轮组安装于转台尾部顶侧,所述桁架结构安装于转台尾部,并通过拉板组与变幅滑轮组相连接,用于在变幅过程中通过拉板组承受变幅力,以增加变幅力臂。所述拉板组的数量为两个,所述拉板组的一端与变幅滑轮组铰接,另一端与桁架结构铰接。所述拉板组包括首、中、尾三段相铰接的拉板,其中,首段拉板的另一端与桁架结构铰接,尾段拉板的另一端与变幅滑轮组铰接。该附加配重支架及履带起重机,通过增加拉板组连接桁架结构与变幅滑轮组,使得在变幅过程中,能够通过拉板组承受变幅力,从而增加变幅力臂,提升整体的起重效果。
