The invention discloses a self-adaptive positioning device for a crane, and relates to the technical field of crane equipment. The crane comprises a crane body, a lifting appliance device is slidably mounted at the top of the crane body, a positioning device is arranged at the bottom of the lifting appliance device and comprises a U-shaped groove frame, the U-shaped groove frame is fixed to the bottom of the lifting appliance device, and arc groove sliding plates are slidably mounted on the left side and the right side of the bottom of the inner wall of the U-shaped groove frame correspondingly; the opposite sides of the arc groove sliding plates on the left side and the right side are elastically connected with the inner wall of the U-shaped groove frame through elastic plates, and protruding columns are fixed to the bottoms of the elastic plates. The arc chute sliding plate is matched with the elastic plate, so that the arc chute sliding plate buffers the steel wire rope of the lifting appliance device through the elastic plate, the problems that the steel wire rope shakes to be separated from the center of the fixing frame and is abraded are solved, and the service life of the steel wire rope of the lifting appliance device is prolonged.
本发明公开了一种用于起重机的自适应定位装置,涉及起重机设备技术领域。本发明包括起重机主体,所述起重机主体的顶部滑动安装有吊具装置,所述吊具装置的底部设置有定位装置,所述定位装置包括U形槽架,所述U形槽架固定在吊具装置的底部,所述U形槽架的内壁底部左侧和右侧均滑动安装有弧槽滑板,左侧和右侧所述弧槽滑板的相向一侧与U形槽架的内壁之间通过弹板弹性连接,所述弹板的底部固定有凸柱。本发明通过弧槽滑板与弹板配合,使得弧槽滑板通过弹板对吊具装置的钢丝绳进行缓冲,从而避免了钢丝绳晃动脱离固定架中心部位,钢丝绳出现磨损的问题,进而延长了吊具装置钢丝绳的使用寿命。
