The invention belongs to the technical field of counterweight moving mechanisms, and relates to a counterweight backward moving mechanism for a crane. Comprising a platform support, a sliding frame is connected to the platform support in a sliding mode, a guide mechanism is arranged between the sliding frame and the platform support, and a telescopic mechanism is arranged on one side of the sliding frame. The sliding frame comprises a lower cover plate, the lower cover plate is located on the lower side of the platform support, upper cover plates are fixed to the left side and the right side of the upper end face of the lower cover plate through connecting assemblies correspondingly, the platform support is located between the two connecting assemblies, and the left end and the right end of the platform support are located on the lower sides of the two upper cover plates correspondingly. The counterweight backward-moving mechanism is installed on the rotary platform of the crane, the counterweight is installed below the sliding frame, the sliding frame is driven to move back and forth through telescoping of the telescoping mechanism, the counterweight also moves along with the sliding frame, and adjustment of the gravity center position of the counterweight is achieved.

    本发明属于平衡重移动机构技术领域,涉及一种起重机用的平衡重后移机构。包括平台支座,所述平台支座上滑动连接有滑架,所述滑架与平台支座之间设置有导向机构,所述滑架的一侧设置有伸缩机构。所述滑架包括下盖板,所述下盖板位于平台支座下侧,所述下盖板的上端面左右两侧分别通过连接组件固定有上盖板,所述平台支座位于两个连接组件之间,且平台支座的左右两端分别位于两个上盖板的下侧。本发明的平衡重后移机构,安装在起重机的回转平台上,平衡重安装在滑架下方,通过伸缩机构的伸缩带动滑架来回移动,平衡重也跟着滑架移动,实现了平衡重重心位置的调整。
