The invention discloses a lifting type hoisting crane for a hydrological ship, and belongs to the technical field of cranes for hydrological ships, the lifting type hoisting crane comprises a supporting seat, a displacement adjusting mechanism and a limiting mechanism, the supporting seat is in bearing connection with a rotating seat, the middle lower part of the rotating seat fixedly penetrates through an extension plate, and the upper end of the rotating seat is in shaft connection with a hoisting arm; a lifting arm is installed at the front end of the lifting arm, a supporting frame is fixedly and vertically installed at the rear end of the extending plate, a servo motor is installed on the portion, between the supporting frame and the rotating base, of the extending plate, the shaft end of the servo motor is connected with one end of a rope winding shaft through a belt transmission set, and the rope winding shaft is connected to the two supporting plates through bearings; and the two supporting plates are vertically and fixedly connected to the upper surface of the extension plate. The lifting mechanism can be adjusted, the lifting range of the crane can be adjusted, in addition, the rope winding structure can be limited through the mass of the heavy object, and therefore safety accidents caused by reverse rotation of the rope winding structure can be avoided.
本发明公开了一种托举式吊运的水文船用起重机,属于水文船用起重机技术领域,包括支撑座、位移调节机构和限位机构,所述支撑座上轴承连接有旋转座,且旋转座的中下部固定贯穿延伸板设置,所述旋转座的上端轴连接有起重臂,且起重臂的前端安装有吊臂,所述延伸板的后端固定垂直安装有支撑框,且支撑框与旋转座之间的延伸板上安装有伺服电机,所述伺服电机的轴端通过皮带传动组与绕绳轴的一端相连接,且绕绳轴轴承连接于2个支撑板上,并且2个支撑板垂直固定连接于延伸板的上表面。该发明能调节托举机构,进而可以调节起重机起吊的范围,另外通过重物的质量,可对绕绳结构进行限位,从而可避免绕绳结构逆向旋转而导致的安全事故。
