Wave-preventing device of railway liquid tank car

Abstract

The invention discloses a wave-preventing device of railway liquid tank car, which has a pair of longitudinal wave-preventing boards which are symmetrically arranged on the inside top of a tank body so as to longitudinally divide the inside top of the tank body into three portions; two sides of the pair of longitudinal wave-preventing boards are symmetrically provided with a plurality of transverse wave-preventing boards and a plurality of transverse middle-dividing boards are arranged between the pair of the longitudinal wave-preventing boards so as to longitudinally and transversely divide the inside top of the tank body into a plurality of chambers; and the longitudinal wave-preventing boards and the transverse wave-preventing boards are integrated with the inside top of the tank body via corresponding supplementary boards. The wave-preventing device can effectively improve dynamics performance of the car, ensure traveling safety, prolong the service life of the car and facilitate the maintenance and the washing for the tank body, and is suitable for the tank car carrying various liquid media.

Description

technical field [0001] The invention relates to a railway liquid tank car, in particular to an anti-wave device for a railway liquid tank car. Background technique [0002] During the transportation of railway liquid tank cars, the fluid medium loaded will have a large hydraulic impact on the tank body, which will affect the dynamic performance of the vehicle, driving safety, and the service life of the vehicle. At present, the transportation of railway liquid tank cars often ensures the safety of the vehicles by controlling the empty volume ratio of the tanks. However, since the density and expansion coefficient of the liquid medium are different, different liquid media require different void volume ratios of the tank, especially liquid media with a large expansion coefficient require a large void volume ratio, so that the liquid medium is in The range of activities in the tank is very large, which has a great impact on the stability of the vehicle's operation, and the hyd...

Problems solved by technology

[0004] First, the single-piece plate is welded in the tank body, which is a cantilever structure. The stress condition is not good, and fatigue cracks are easy to occur at the connection position with the tank body, which in turn causes damage to the base material of the tank body, and the base material of the tank body is damaged by waves. The phenomenon that the board is torn causes the tank car to leak and seriously affects the safety of railway transportation

[0005] Second, the semicircular or annular anti-wave plate can only prevent the longitudinal liquid impact in the tank, but cannot control the horizontal liquid impact in the tank, and does not greatly improve the stability of the vehicle

[0006] Third, the semicircular or annular anti-wave plate divides the tank body into several chambers longitudinally, which not only occupies the lower space of the tank body, but also prevents the staff from walking freely in the tank body, resulting in extremely difficult maintenance and cleaning of the tank body. inconvenient
