The invention relates to the technical field of limiters, and discloses a tower crane position limiter structure which comprises a shell, a microswitch is welded between the left inner wall and the right inner wall of the shell, the bottom of the microswitch is rotationally connected with a trigger wheel, a driving shaft is inserted into the inner rear wall of the shell, the driving shaft is sleeved with a rotating cam, and the rotating cam is rotationally connected with the left inner wall and the right inner wall of the shell. A fixing mechanism is welded to the inner right wall of the shell, and an adjusting mechanism is welded to the inner bottom wall of the shell. An ejector rod is inserted into a fixing cylinder, a wedge-shaped block is pushed leftwards, then an extrusion plate is driven to extrude a pressing rod leftwards, the pressing rod is extruded to be tightly attached to a driving shaft, static friction force is generated between the pressing rod and the driving shaft, and when the driving shaft rotates, a fixing pipe and a rotating cam are driven to rotate synchronously through the friction force between the driving shaft and the pressing rod; therefore, the rotating cam and the driving shaft are fixed together through extrusion of the ejector rod, screw connection is reduced, installation is simple, and the effect that the driving shaft and the rotating cam are fixed together is achieved.
本发明涉及限制器技术领域,且公开了一种塔吊位置限制器结构,包括壳体,所述壳体左右内壁之间焊接有微动开关,所述微动开关的底部转动连接有触发轮,所述壳体的内后壁插接有驱动轴,所述驱动轴的外部套接有转动凸轮,所述壳体的内右壁焊接有固定机构,所述壳体的内底壁焊接有调节机构。通过顶杆插在固定筒内,向左推动楔形块,进而带动挤压板向左挤压压杆,压杆受到挤压紧贴驱动轴,与驱动轴之间产生静摩擦力,驱动轴转动时通过与压杆之间的摩擦力带动固定管和转动凸轮同步转动,故通过顶杆的挤压将转动凸轮与驱动轴固定在一起,减少了螺钉连接,安装比较简单,从而达到了将驱动轴与转动凸轮固定在一起的效果。
