Description

Technical Field

[0001] This utility model relates to the field of track engineering technology, specifically a trolley for taking sleepers on ballast railway lines. Background Technology

[0002] Railway tracks, also known as rails, are mainly used on railways and work in conjunction with switches to allow trains to travel without turning. Railway tracks typically consist of two parallel steel rails, which are fixed on sleepers, with ballast underneath the sleepers.

[0003] A search revealed that the announcement number is CN221739736U, and the name is "A sleeper replacement trolley, including a bottom support frame." Research and analysis showed that this device solves the technical problems of the single moving mode of cranes in the prior art and the increased maintenance and management costs caused by the need to use additional equipment to tie sleepers. However, it still has the following disadvantages to some extent.

[0004] For example, when using this equipment, it is not possible to directly remove the sleeper components from under the track. A section of track needs to be dismantled before the sleeper components can be replaced. Due to factors such as short track maintenance window time and narrow working space, large sleeper replacement machinery is difficult to enter the site for operation. This not only results in low work efficiency but also takes a long time, which can easily affect the operation of the railway. In order to solve the above technical problems, we have designed a sleeper removal trolley for ballast railway lines. Utility Model Content
