The invention relates to the technical field of lifting arms, and discloses a lifting arm for a mining machine, which comprises a mounting plate, a supporting piece is rotatably mounted at one end of the mounting plate, a sliding block is rotatably connected to the other end of the supporting piece, a pinch bar is slidably mounted outside the sliding block, and a driving piece for driving one end of the pinch bar to move up and down is arranged on the mounting plate. According to the lifting arm for the mining machine, the length of a force arm of the lifting arm can be conveniently adjusted, meanwhile, it is guaranteed that the linear distance from a supporting point to a driving point cannot be changed, position adjustment of a driving piece is reduced, the installation height of the whole lifting arm can be adjusted, and the lifting arm is high in applicability and worthy of popularization.

    本发明涉及提升臂技术领域,公开了一种矿机用提升臂,包括安装板,所述安装板的一端转动安装有支撑件,所述支撑件的另一端转动连接有滑块,所述滑块外滑动安装有撬杆,所述安装板上设有撬杆的一端进行上下移动的驱动件,本发明一种矿机用提升臂,不仅方便进行调整其力臂的长度,同时还保证了支撑点到驱动点的直线距离不会发生改变,减少了驱动件的位置调整,以及可调整整个提升臂的安装高度,适用性强,值得推广。
