Description

Continuous pillow changing operation train and operation method

technical field

The application relates to the field of railway engineering operations, in particular to a continuous sleeper changing operation train and an operation method.

Background technique

Railway pillow replacement is one of the main tasks in the mechanized maintenance of railway lines. With the continuous development of engineering technology, the work of changing pillows has changed from traditional all-manual work to small machinery and large-scale road maintenance machinery, which shortens the time for changing pillows, reduces the labor intensity of construction personnel, reduces staffing, and facilitates management.

At present, there are two main methods of using small machines to replace sleepers: one is to use small machines to cooperate with track raising equipment to move the sleepers sideways from the line and perform side-extraction replacement; the other is to use road-rail dual-purpose excavators The machine cooperates with the sleeper fixture for construction. Both of these two schemes need to transport the new sleeper to both sides of the track where the sleeper is to be replaced in advance. After the replacement is completed, the old sleeper placed on both sides of the track needs to be transported away. Multiple transportation processes are required; and after the sleeper is replaced, the fasteners need to be manually installed, requiring a lot of manual cooperation, the steps are cumbersome and the efficiency is low. In addition, in the existing technology, railway sleeper replacement generally does not deal with the sleeper bed, and the construction quality is not high; therefore, subsequent steps are required to process the sleeper bed, resulting in more processes and poor continuity, which in turn leads to sleeper replacement. The whole process lasts for a long time, which greatly affects the normal operation of the railway.

The use of large-scale road maintenance machinery to replace sleepers is carried out in the way of overhauling trains. To change sleepers in overhaul trains, the track needs to be cut off. Generally, sleeper replacement and track replacement are performed at the same time, and the construction efficiency is low. Since the track needs to be cut during construction, the track needs to be welded to restore the line to a seamless line after the construction is completed, which increases the construction steps and maintenance costs.

In view of this, the present application is proposed.
