Abstract

The invention discloses a manhole device. The manhole device is arranged on a tank body of a tank car; a manhole is formed in the tank body; the manhole device comprises a manhole seat, a flange disc, a manhole cover and a loading and unloading hole cover; a through hole is formed in the middle of the manhole seat; a first end of the manhole seat is fixed in the manhole; the through hole is communicated with the tank body; the flange disc is fixed at a second end, relative to the first end, on the manhole seat; the manhole cover covers the second end of the manhole seat, and is fixed on the flange disc; a loading and unloading hole is formed in the manhole cover; and the loading and unloading hole cover is detachably fixed in the loading and unloading hole. By opening the manhole and opening the loading and unloading hole in the manhole cover covering the manhole, the loading and unloading hole is not opened on the tank body, so that the manufacturing of the tank body is simplified and the strength and the rigidity of the tank body are guaranteed.

Description

technical field [0001] The invention relates to the technical field of vehicle transportation, in particular to a manhole device. Background technique [0002] With the continuous development of trade exchanges between my country and other countries in the world, and the continuous enhancement of my country's economic strength, especially the continuous improvement of manufacturing technology and production capacity, as well as the continuous improvement of the technology and quality of export products. Driven by the rapid development of railway manufacturing equipment, more and more railway equipment independently designed and produced are going abroad and going to the world. [0003] The barrel of the current railway sulfuric acid tank car is a cylinder or an inclined cone, the upper part is equipped with manholes, loading and unloading ports and air inlets, and the lower part is equipped with welded liquid collection nests and upper saddle plates. The cylindrical tank bo...
