The invention provides a tank and a railway tank car. The tank provided by the invention comprises a tank body, a manhole and a manhole cover; the manhole is arranged on the tank body; the manhole cover is connected with the manhole; a plurality of first gaps and a first circular hole are formed in the edge position of the manhole cover; a plurality of second gaps and a second circular hole are formed in the edge position of the side wall of the manhole; the first gaps and the second gaps are arranged in manner of matching; the first circular hole and the second circular hole are arranged in amatching manner; when the manhole cover is opened, the manhole and the manhole cover are connected through a first swing bolt; when the manhole is sealed by the manhole cover, after second swing bolts pass through the second gaps and the first gaps correspondingly, the manhole cover and the manhole are tightly connected through second nuts; and after the first swing bolt passes through the secondcircular hole and the first circular hole, the manhole cover and the manhole are tightly connected through a first nut. The tank and the railway tank car provided by the invention are simple to process and relatively low in cost.
Description
technical field [0001] The invention relates to railway transportation technology, in particular to a tank body and a railway tank car. Background technique [0002] The tank body of the railway tank car is equipped with manholes, which are used for people to enter the tank body for cleaning, maintenance, installation and disassembly of the internal structure of the tank body. A manhole cover is provided above the manhole to close the manhole after the items are loaded into the tank. [0003] The manhole cover in the prior art has a curved surface structure, and is connected with the manhole through a hinged joint. The manhole cover can be turned around the hinged axis to realize opening and closing. [0004] However, the manhole cover of this structure is formed by stamping. Since the curved surface structure is relatively complicated, the process of stamping is relatively difficult, which increases the cost of the equipment. Contents of the invention [0005] The inven...
