The invention discloses a
mechanics-
electronics-hydraulics-integrated sleeper replacing
machine. The
mechanics-
electronics-hydraulics-integrated sleeper replacing
machine is composed of a four-nut synchronous assembling-disassembling device, a first sleeper lifting device, a sleeper-transferring and sleeper-push-pull device, a sleeper hoisting transporting device, a power generator, a hydraulic
system and
control system cabinet and a rail car. The rail car comprises a plurality of castors and two longitudinal beams, the four-nut synchronous assembling-disassembling device, the first sleeper lifting device, the sleeper-transferring and sleeper-push-pull device, the sleeper hoisting transporting device, the power generator and the hydraulic
system and
control system cabinet are arranged on the two longitudinal beams of the rail car, and the rail car is drawn through an
engineering van. According to the
mechanics-
electronics-hydraulics-integrated sleeper replacing
machine, the working devices can be rapidly aligned with the working position; four nuts can be synchronously assembled or disassembled, pre-tightening force of four nuts is coincident accordingly, the fatigue life of bolts is prolonged, and the reliability of connection between sleepers and steel rails is guaranteed; rapid hoisting transporting and placing work of sleepers is achieved; the mechanics-electronics-hydraulics-integrated sleeper replacing machine adapts to sleeper replacement of linear and curved rail sections; the sleeper-transferring and sleeper-push-pull device is an integrated device, the structure is simple and compact,
automatic control is achieved, operation is convenient, and the sleeper replacement working efficiency is high.
