The invention relates to a device for carrying out 180-degree overturning on a large steel member. An overturning machine for a large steel member comprises a travelling assembly, a lifting mechanismand an overturning assembly, wherein the overturning assembly is fixed to the travelling assembly through the lifting mechanism. The travelling assembly comprises a base provided with travelling wheels and a guide rail arranged in a manner of being matched with the travelling assembly; an oil cylinder is adopted for driving for the travelling assembly; and the oil cylinder is fixed to the ground,and the travelling assembly is connected to the front end of a piston rod of the oil cylinder. According to an underground overturning device for a large steel member, one overturning machine for thelarge steel member is arranged in two parallel pits separately, and working supports are arranged at the two sides of each pit or a working support is arranged at one side of each pit; and the heightof the overturning machine after lifting is greater than the height of the working support. According to the overturning machine for the large steel member, hydraulic drive is adopted for horizontal travelling; a locked hydraulic oil channel and hydraulic oil are capable of absorbing a certain impact force; and in the case of a too high impact force, the impact force can be released through an overflow valve, so that locking for the position of the overturning machine is ensured, and damage to the overturning machine is avoided.

    本发明涉及一种对大型钢构件180°翻转的装置。一种大型钢构件翻转机,包括行走组件、举升机构以及翻转组件,所述翻转组件通过举升机构固定于行走组件上。所述行走组件包括安装有行走轮的底座以及与行走组件匹配设置的导轨,行走组件的驱动采用油缸,油缸固定于地面,其活塞杆前端连接行走组件。一种地藏式大型钢构件翻转装置,在并排的两个地坑内分别设置一个如前所述的大型钢构件翻转机,每个地坑的两侧或其一侧设置工作支架;翻转机举升后的高度高于工作支架。本发明大型钢构件翻转装置,水平行走采用液压驱动,锁死的液压油路及液压油能吸收一定的冲击力,冲击力过大时,经过溢流阀可以释放冲击力,即保证了翻转机位置的锁定,又避免了对翻转机的损坏。
