Technical Field

[0001] The utility model belongs to the technical field of rail equipment, and in particular relates to an angle rotation fixing structure of a rail flatbed car. Background Art

[0002] Railways are track lines used by trains and other vehicles, and rail transportation plays a particularly important role in economic and social development. During railway construction and maintenance, specialized flatbed trucks are often used to save time and effort. Currently, high-altitude work equipment is mounted on a flatbed truck, moved to the construction site, and then secured to the railway for construction. However, this only works directly above the flatbed truck. Once one operation is completed, the flatbed truck must be unsecured from the railway and moved to another location for construction, which is time-consuming and inefficient. Summary of the Invention
