The invention relates to the technical field of engineering machinery, and provides a counterweight displacement device and an operation machine.The counterweight displacement device comprises a lug plate, a first driving mechanism, a first detection element used for detecting the horizontal position of the lug plate, a sliding plate used for supporting a counterweight, a lifting driving mechanism and a controller, the lug plate is in sliding connection with a winch box of the operation machinery, and the lug plate is used for being connected with the counterweight; the first driving mechanism drives the lug plate to horizontally move in the direction close to or away from the operation mechanical rotary table. The second driving mechanism is used for driving the sliding plate to move, and the sliding plate and the lug plate are consistent in moving path; the lifting driving mechanism is arranged on the operation machine frame and used for driving the sliding plate to ascend and descend. The controller controls the first driving mechanism and the second driving mechanism to stop according to detection signals of the first detection element, so that the lug plate is matched with the balance weight in horizontal position. Accurate alignment of the balance weight and the lug plate can be achieved, the lifting driving mechanism is arranged on the vehicle frame, the gravity of the borne balance weight can be transmitted to the vehicle frame, and the phenomena of oil way abrasion and the like do not exist.

    本发明涉及工程机械技术领域,提供一种配重变位装置及作业机械,包括耳板、第一驱动机构、用于检测耳板水平位置的第一检测元件、用于支撑配重的滑移板、升降驱动机构和控制器,耳板与作业机械的卷扬箱滑动连接,耳板用于连接配重;第一驱动机构驱动耳板沿靠近或远离作业机械转台的方向水平移动;第二驱动机构用于驱动滑移板移动,滑移板与耳板的移动路径一致;升降驱动机构设在作业机械车架上,用于驱动滑移板升降;控制器根据第一检测元件的检测信号分别控制第一驱动机构和第二驱动机构停机、使耳板和配重的水平位置相适配。可实现配重与耳板的准确对位,升降驱动机构设在车架上,可将受到的配重的重力传递给车架,且不存在油路磨损等现象。
