The invention relates to the technical field of engineering machinery, and discloses a crawler frame with a reinforced web structure for a crane. The crawler frame comprises a mounting shell, the bottom of the mounting shell is fixedly connected with a lower mounting seat, the inner wall of the lower mounting seat is fixedly connected with a first shaft sleeve, the inner wall of the first shaft sleeve is movably connected with first ball rollers, a supporting frame is fixedly connected to the top of the mounting shell, a mounting cylinder is fixedly connected to the top of the supporting frame, a buffer spring is fixedly connected to the inner wall of the mounting cylinder, and an upper mounting base is fixedly connected to one end of the buffer spring. According to the crawler frame withthe reinforced web structure for the crane, the purpose of small abrasion of thrust wheels and the crawler frame can be achieved, when a crawler runs, friction is changed into rolling friction throughthe first ball rollers and second ball rollers, so that abrasion is reduced, and the problem that abrasion between a crawler frame thrust wheel and a crawler frame of a general crane with a reinforced web structure is large is solved.

    本发明涉及工程机械技术领域,且公开了一种具有加强腹板结构的起重机用履带架,包括安装壳体,所述安装壳体的底部固定连接有下安装座,所述下安装座的内壁固定连接有第一轴套,所述第一轴套的内壁活动连接有第一球滚子,所述安装壳体的顶部固定连接有支撑架,所述支撑架的顶部固定连接有安装筒,所述安装筒的内壁固定连接有缓冲弹簧,所述缓冲弹簧的一端固定连接有上安装座。该具有加强腹板结构的起重机用履带架,能够达到支重轮与履带架磨损小的目的,在履带运转时,通过第一球滚子和第二球滚子将摩擦装换为滚动摩擦,减少了磨损,解决了一般具有加强腹板结构的起重机用履带架支重轮与履带架磨损大的问题。
