The invention discloses a mechanical sleeper replacing
machine. The mechanical sleeper replacing
machine is composed of a vibration stone pushing device, a four nut synchronous mounting and dismounting device, a rail lifting and sleeper rotating device, a sleeper pushing and pulling device, a sleeper hoisting device, a vibration rotary excavating type stone removing device, a rail car, a power generator, a hydraulic
system box, a first camera shooting component, a second camera shooting component, a third camera shooting component, a fourth camera shooting component, a fifth camera shooting component, a sixth camera shooting component and a monitor, wherein the rail car is provided with multiple trundles and two longitudinal beams, the vibration stone pushing device, the four nut synchronous mounting and dismounting device, the rail lifting and sleeper rotating device, the sleeper pushing and pulling device, the sleeper hoisting device, the vibration rotary excavating type stone removing device, the power generator and the hydraulic
system box are arranged on the two longitudinal beams of the rail car, and the monitor is arranged in a
tractor cab. According to the mechanical sleeper replacing
machine, a working device can be aligned with a working position quickly, requirements for quick sleeper replacement on linear and curve rail sections can be met, automatic
program control can be achieved easily, and limited
train passing gaps for track maintenance can be fully and reasonably utilized to achieve sleeper replacement.
