The invention relates to the field of cranes, in particular to a crane balancing weight positioning device which comprises a machine body, and a balancing weight is mounted on a rotary table of the machine body. The end face of the limiting block extends into the rectangular opening, a cushion block is arranged on the lower surface of the limiting block and extrudes the inner bottom face of the through hole, and an inclined face is arranged on the upper edge of the inner end of the through hole. Fixing grooves are formed in the two sides of the balancing weight, the balancing weight is slidably connected into the rectangular opening, and the end of the limiting block is embedded into the fixing grooves; the rectangular opening can restrain swinging of the balancing weight, swinging of the balancing weight can be reduced, personnel can operate the balancing weight conveniently, when the balancing weight is taken down, the balancing weight is lifted, the fixing groove pushes the limiting block upwards, then the protruding part extrudes the limiting block, the limiting block is extruded and rotated into the through hole, and in other words, the limiting block can be taken down. At the moment, the balancing weight moves up and down in the rectangular opening and is not restrained by the limiting block, and the balancing weight is lifted and taken down; the mounting is convenient, meanwhile, the taking-down is relatively convenient, and the fixation is more convenient compared with the fixation through bolts.
本发明涉及起重机领域,具体是一种起重机配重块的定位装置,包括机体,配重块安装在机体的转台上;限位块的端面延伸矩形口内,限位块的下表面设有垫块,垫块挤压在通孔内底面,通孔的孔内端上边缘设有斜面;所述配重块两侧开设固定槽,配重块滑动连接在矩形口内,限位块的端部嵌入在固定槽内;矩形口对配重块的摆动可进行约束,降低配重块的摆动,方便人员对配重块的操作,以及在取下配重块时,上提配重块,固定槽上推限位块,之后凸部挤压限位块,此时限位块被挤压转动至通孔内,即,此时的配重块在矩形口内上下移动没有限位块的约束,将配重块升吊取下;安装方便,同时取下也较为方便,相对通过螺栓固定更加便捷。
