The invention relates to the technical field of tunnel segment hoisting, and particularly discloses a segment hoisting machine with a front-end auxiliary supporting function, which comprises a rail, a sliding frame is slidably connected to the rail, a hoisting assembly and a transmission unit for driving the hoisting assembly and the sliding frame are arranged on the sliding frame, and a cooling unit is further arranged on the sliding frame. The lifting assembly comprises a front end supporting frame, an auxiliary pitching arm and a main pitching arm. The main pitching arm and the auxiliary pitching arm are used in cooperation with the hanger rail, heavy duct pieces can be hoisted, and the stability of the duct pieces is not affected; the lifting machine is large in lifting clearance amplitude, and the lifting machine can be used in a tunnel with large gradient or space limitation; the hydraulic oil in the oil return pipe is detected in real time through the temperature sensor in the cooling unit, so that the double-air cooler is controlled to be flexibly opened or closed, the hydraulic oil in the hydraulic system of the lifting machine is cooled, unnecessary industrial energy consumption waste is avoided, and the stability and reliability of the hydraulic system of the lifting machine are guaranteed.
本发明涉及隧道管片吊运技术领域,具体公开了一种具有前端辅助支撑功能的管片吊运机,包括轨道,轨道上滑动连接有滑架,滑架上设置有起吊组件以及用于驱动起吊组件和滑架用的传动单元,滑架上还设置有冷却单元,起吊组件包括前端支撑架和辅助俯仰臂以及主俯仰臂;本发明通过主俯仰臂上和辅助俯仰臂配合吊轨使用,可以吊运较重管片且不影响其稳定性;本吊运机的起吊净空幅度大,有利于其在坡度较大或具有空间局限性的隧道内进行使用;通过冷却单元中温度传感器对回油管内液压油进行实时检测,以控制双风冷却器灵活开启或关闭,使其对吊运机的液压系统中液压油进行冷却处理,避免了不必要的工业能耗浪费,保障了吊运机液压系统的稳定性和可靠性。
