The invention relates to a mechanical structure for increasing the hoisting stroke of a hydraulic cylinder hoisting beam, which comprises a beam body, a driving assembly is arranged on the beam body, a hoisting assembly is arranged on the inner side of the beam body, a leveling assembly is arranged at the upper end part of the beam body, the driving assembly comprises a chain, one end of the chain is fixedly connected with the inner side of the beam body, and the other end of the chain is fixedly connected with the hoisting assembly. The other end of the chain penetrates through and extends to the outer side of the beam body, the inner side wall of the beam body is in shaft connection with a fixed pulley, one end of the fixed pulley abuts against the chain, a hydraulic cylinder is fixedly installed on the inner side wall of the beam body, and the output end of the hydraulic cylinder is fixedly connected with a connecting frame. According to the mechanical structure for increasing the lifting stroke of the lifting beam of the hydraulic cylinder, the hydraulic cylinder is adopted to drive the movable pulley, the advantage of large thrust of the oil cylinder is exerted, the lifting stroke is doubled, the situation that an underground roadway fluctuates greatly is met, the guide wheel and the chain wheel are used for controlling the chain to operate horizontally and preventing the chain from skewing, and safe operation of equipment is guaranteed.

    本发明涉及一种增加液压缸起吊梁起吊行程的机械结构,包括梁体,所述梁体上设置有驱动组件,所述梁体的内侧设置有起吊组件,所述梁体的上端部设置有调平组件,所述驱动组件包括一端与梁体的内侧固定连接的链条,所述链条的另一端贯穿并延伸至梁体的外侧,所述梁体的内侧壁轴连接有一端与链条相抵触的定滑轮,所述梁体的内侧壁固定安装有液压缸,所述液压缸的输出端固定连接有连接架。该增加液压缸起吊梁起吊行程的机械结构,通过采用液压缸驱动动滑轮的形式,发挥油缸大推力优势,将提升行程增大一倍,满足井下巷道起伏较大的情况,而通过导向轮与链轮控制链条水平运行,防止链条扭斜,保证设备的安全运行。
