Wave suppressor for railroad tanker

Abstract

A wave suppressor for a railroad tanker relates to tankers used for conveying liquids, and is particularly used in the tanker. The wave suppressor comprises swash plates and a mounting seat, wherein the mounting seat is fixed on the inner wall of the tanker; the swash plates are fixed on the mounting seat. The wave suppressor is mainly characterized in that the swash plates are fixed on two sides of the mounting seat at equal intervals in a fence-shaped manner; the middle, in the length direction, of each swash plate is convex to form a cap top; brims are arranged on two sides on the lower edge of the cap top to form a cap-shaped structure. The wave suppressor has the benefits that the cap-shaped structure of the swash plate meets the movement regularity of hydromechanics, so as to reduce longitudinal impact and regurgitation force of a liquid in the tanker effectively, effectively overcome the defects of non-uniform stress on the conventional swash plates suffering from fluid impact and non-uniform overflow, reduce longitudinal impact on a sealing head of the tanker, ensure running safety and prolong the service lives of the swash plates.

Description

Technical field: [0001] The utility model relates to a wave-proof device for a railway tank car, which relates to a tank car used for transporting liquid, in particular to a wave-proof device inside the tank car. Background technique: [0002] At present, there are few railway tank cars with anti-wave devices in tanks in our country, but with the increase of the running speed of the trucks, the load of the trucks and the increase of the traction tonnage, the longitudinal impact on the head of the tank car gradually increases. In order to prevent accidents and improve driving safety, an anti-wave device is required in the tank car. Some anti-wave devices for tank cars are also disclosed in the patent application, but the anti-wave plates of these anti-wave devices are mostly in the form of partition walls, which are formed by setting overflow holes on a steel plate. This anti-wave device has the following disadvantages: 1. Due to the complex force of the medium in the tank w...

AI Technical Summary

Problems solved by technology

This anti-wave device has the following disadvantages: 1. Due to the complex force of the medium in the tank when the vehicle is running, the wave-proof plate is unevenly stressed when the fluid impacts, the overflow is uneven, and the longitudinal impact on the head of the tank car is large, which is not conducive to Driving safety; 2. The steel plate is easily damaged, and the entire steel plate needs to be replaced during maintenance, which is too expensive and inconvenient to replace; 3. The anti-wave plate and the tank body are of welded structure, and the root of the mounting seat is easy to be damaged when the medium in the tank moves. Stress concentration shortens the service life of the anti-wave plate

The anti-wave board with this structure improves the tear resistance of the anti-wave board to a certain extent, but due to its structural limitations, the anti-wave board still cannot adapt to the complex stress of the medium in the tank, and cannot effectively deal with the liquid in the tank. Longitudinal impact force and rebound force cannot effectively reduce the longitudinal impact on the head of the tanker to ensure driving safety
