Tank car tank body and tank car chassis connection device and railway tank car

Abstract

The invention provides a tank car tank body and tank car chassis connection device and a railway tank car, the device includes: two end supports, two saddles, longitudinal supports, two first fastening devices, a second fastening device device, the third fastening device; one end support is used to install at the head of the tank car body, and the other end support is used to install at the other head; one saddle is used to install at the tank car One corbel of the tank body, another saddle is used to install at the other corbel; the end support is fixedly installed on the tank truck chassis through the first fastening device; the saddle is fixed and installed through the second fastening device On the bottom frame of the tank car; the longitudinal support is fixedly installed on the bottom frame of the tank car through the third fastening device; the two end supports, two saddles, and the longitudinal support are fixed on the bottom frame of the tank car to form a U-shaped structure. The invention can satisfy the strength index of the tank body of the tanker, effectively prevents the deformation of the tank body of the tanker, improves safety, and increases the load and transport speed of the tanker.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of railway vehicles, in particular to a tank car tank body and tank car chassis connecting device and a railway tank car. Background technique [0002] Tanker is a tank-shaped transport vehicle used to transport various liquids, liquefied gases and powdered goods, such as gasoline, crude oil, various viscous oils, vegetable oils, liquid ammonia, alcohol, water, various acids Alkali liquid, cement lead oxide powder, etc., tank trucks play an important role in transportation. Among them, the concentrated nitric acid medium is highly corrosive, so it needs to be transported by an aluminum tank car with good corrosion resistance. The tank car includes the tank body and the chassis. At present, the front and rear ends of the tank body and the chassis are mainly made of Belt connection, the middle part is connected by upper and lower saddles, and the end part is connected by a combined b...

Problems solved by technology

Among them, the concentrated nitric acid medium is highly corrosive, so it needs to be transported by an aluminum tank car with good corrosion resistance. The tank car includes the tank body and the chassis. At present, the front and rear ends of the tank body and the chassis are mainly made of Belt connection, the middle part is connected by upper and lower saddles, and the end part is connected by a combined bracket to fix the tank body on the bottom frame; however, because the aluminum tank car is made of pure aluminum material, it is relatively soft and easily deformed. However, the connection between the tank body and the bottom frame is connected and fixed by the upper and lower saddles, which cannot meet the strength index of the tank body and easily lead to deformation of the tank body, which affects the improvement of the tanker's load and transportation speed
