DETAILED DESCRIPTION

[0016] The specific technical scheme of the present application is further described below, so that the purpose, technical scheme and advantages of the present application are more clear, and the technical personnel in the art can further understand the present application. The technical scheme in the present application will be clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all the embodiments, and do not constitute a limitation on the rights. Based on the embodiments in the present application, all other embodiments obtained by the ordinary technical personnel without creative labor belong to the scope of protection of the present application.

[0017] A large crane pipe automatic cover closing sealing device, comprising a truss type loading crane pipe, a sealing cover assembly and a cover-pulling device,

[0018] The sealing cover assembly comprises a double-sided glue-hung sealing cover plate arranged at the bottom of the sealing cap for abutting with the train tank opening, a loading opening is arranged in the middle part of the double-sided glue-hung sealing cover plate, and a spring hinge cover is arranged at the loading opening,

[0019] The cover-pulling device comprises a left cover-pulling mechanism and a right cover-pulling mechanism,
