Description

Technical Field

[0001] The utility model relates to the technical field of rail transportation, in particular to a disassembly and assembly device of a vertical bolt and a sleeper adjustment device. Background Art

[0002] In the maintenance and construction of railway tracks, the disassembly and assembly of vertical bolts is an important and tedious task. For example, vertical bolts are usually screwed on railway sleepers to fix the sleepers. For another example, due to long-term vibration of the track, the vertical bolts on the sleepers are prone to loosening, so the tightness of the vertical bolts needs to be adjusted. In addition, due to the rolling of ballast particles and other reasons, the sleepers are prone to skew. When the skewness reaches a certain degree, it will have an adverse effect on railway driving. Therefore, it is necessary to manually disassemble the vertical bolts on the sleepers to correct the sleepers.

[0003] However, the traditional method of disassembling and assembling vertical bolts mainly relies on manual operation, which not only has low disassembly and assembly efficiency, but also easily causes personnel fatigue and safety accidents. Therefore, a disassembly and assembly device for vertical bolts is needed, which can efficiently disassemble and assemble vertical bolts. Utility Model Content
