Description

Background

The rail is an integral engineering structure, mainly composed of steel rail, sleeper, connecting parts, ballast bed, anti-climbing equipment and turnout, etc., the sleeper is a support of the steel rail, mainly bearing the pressure transmitted from the steel rail and transmitting it to the ballast bed, and the sleeper also plays a role in keeping the position and track gauge of the steel rail. Along with the rapid development of high-speed and heavy-load railway lines, the life cycle of the sleeper is shortened, and the sleeper is replaced slowly in order to ensure the normal running of the lines. The seamless line has been developed from a common seamless line to an interval and a cross-interval seamless line, and has become a main track structure of a railway line in China, and has higher requirements for sleeper replacement.

At present, the domestic seamless line sleeper replacement construction mode mainly comprises the following steps: the pillow replacement method comprises three modes of manual pillow replacement, pillow replacement of a pillow replacement excavator and continuous pillow replacement of a large road maintenance machine. The manual sleeper replacement is generally operated by adopting a method for removing railway ballasts among the sleeper, and during construction, the railway ballasts in the sleeper box are removed until the railway ballasts are lower than the bottom surface of the sleeper, and then a single sleeper to be replaced is moved to a emptying position for extraction. The pillow replacing excavator is used for replacing the pillow, the pillow replacing mode is that a single sleeper is replaced, the pillow replacing excavator is matched with a multifunctional sleeper grabbing device mode by a small excavator, and the problems of multiple operation points and high difficulty of construction organization exist. The continuous sleeper replacement of the large road maintenance machine mainly introduces a overhaul train, and the overhaul train can replace the steel rail and the sleeper simultaneously or can replace the steel rail or the sleeper separately, but still has certain limitation: the construction participants are more, the cooperation workload is large, the operation efficiency is lower, and the integrity of a seamless line can be damaged when the rail cutting operation is needed.
