Embodiment Construction

[0015] see figure 1 , the railway tank car manhole cover of the present invention comprises a reinforcing ring 1, a reinforcing rib 3, a sealing groove 4, an inclined surface 5, a connecting hole 6, a cover body 7, a first boss 8, a second boss 9, a retaining post 10, The handle 11; the cover body 7 is integrated with other parts to play a sealing role. The manhole cover of the present invention is made of non-metallic material, and the sealing groove 4 arranged on the cover body 7 can be directly formed during the injection molding process, thereby reducing the processing steps. In view of the strength and rigidity of the non-metallic material that the manhole cover of the present invention adopts is small, therefore the reinforcement ring 1 is set on the inside of the cover body 7, the reinforcement ring 1 and the cover body are concentric circle structures, and the reinforcement ring can be one or more, with two better. One first boss 8 is arranged at the pin connection p...

Abstract

The invention provides a manhole cover for a railway tank wagon. The manhole cover comprises a cover body, wherein the cover body is a nonmetal cover body. The manhole cover is made of a nonmetal material, so that the manhole cover is light in weight and convenient to assemble, and meets the requirement of the transportation of common media of the railway tank wagon.

Description

technical field [0001] The invention relates to a manhole cover for a railway tank car, in particular to a manhole cover for a railway tank car made of non-metallic material. Background technique [0002] There is a manhole cover on the top of the railway tank car, which is the sealing cover of the manhole on the top of the tank and is an important part of the railway tank car. The existing materials for the manhole cover of the railway tank car include cast iron, stainless steel and carbon steel, and the material density is high. heavier. The material of ship manhole cover is aluminum or aluminum alloy. Now the weight of the cast iron manhole cover is 21.6Kg, and the opening work is intensive and difficult during the operation, and the safety of the operation will also be affected. Contents of the invention [0003] In order to solve the technical problems existing in the background technology, the present invention proposes a railway tank car manhole cover, which uses ...
