Problems solved by technology

[0003] At present, the filling door is made of steel plate, and the opening and closing function is realized through the hinge installed on the side of the filling port. Since there is no operating space inside, it can only be opened to the outside, and there is a potential risk of exceeding the vehicle limit if it is not closed , and has no ventilation effect, the ventilation efficiency of the operation room is low, and there is a huge danger of explosion caused by a large amount of dangerous gas accumulation inside the operation room

Abstract

The invention belongs to the technical field of railway vehicles and particularly relates to a lift type filling door for a tank wagon. The filling door comprises a fixed border, a door body assembly, a bolt and a locking mechanism. The fixed border comprises an upper border body, a lower border body, a left track and a right track which are sequentially welded. The door body assembly comprises a moving door, a U-type handle and sliding assemblies. The U-type handle is installed on the upper portion of the moving door. At least two sets of sliding assemblies are arranged and installed at the two sides of the moving door, so that the moving door moves up and down. The locking mechanism is installed on the upper border body, and when the moving door moves upwards to the maximum position, the locking mechanism hooks the handle to fix the moving door; the bolt is installed at the left side or the right side of the moving door, and when the moving door moves downwards to the maximum position, the bolt fixes the moving door. The filling door is convenient to operate, and safety is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of railway vehicles, and in particular relates to a pull-type filling door for railway tank cars. Background technique [0002] The discharge system of some special railway tank cars is located at one end of the tank head, and its protective shell is the operation room. When loading and unloading the medium in the tank, the staff will fill the external pipeline in the station through the filling tube installed on the side wall of the operation room. The door is docked with the internal piping. [0003] At present, the filling door is made of steel plate, and the opening and closing function is realized through the hinge installed on the side of the filling port. Since there is no operating space inside, it can only be opened to the outside, and there is a potential risk of exceeding the vehicle limit if it is not closed , and has no ventilation function, the ventilation efficiency of the operation room is l...
