a tank car

Abstract

The invention discloses a tank truck. The tank truck comprises a bottom frame and a tank body fixedly mounted on the bottom frame, the bottom frame is integrally provided with a guide rail with the rectangular cross section along the central axis in the traveling direction, two inserted-L-shaped brackets are fixed to the two sides of the guide rail correspondingly, vertical sections of the brackets are arranged perpendicular to the surface of the bottom frame, horizontal sections of the brackets are arranged oppositely, and the two brackets are arranged in a mirror symmetry mode with the guiderail as a symmetrical axis; a strip-shaped sliding groove in sliding fit with the guide rail is formed in the bottom face of the tank body, so that the tank body is located on the central axis of thebottom frame when the sliding groove and the guide rail are matched; and two lug plates which are parallel to the surface of the bottom frame and extend towards the outer side of the tank body are further arranged on the two side faces of the tank body correspondingly, a sliding column is perpendicularly fixed to the upper surface of each lug plate, and a vertical stop block directly facing the tank body is further arranged at the position, close to a truck head, of the bottom frame. According to the tank truck, centralized impact of liquid on the front end of the tank body can be buffered effectively step by step, and the safety of the tank truck during braking is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of vehicles, in particular to a tank truck for transporting liquid. 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 occupy a very important position in transportation, accounting for about 18% of the total number of trucks. Although there are many types of tank trucks, all of them are integral load-bearing structures. The body of most tank trucks is composed of two parts: the tank body and the chassis, and usually the tank body of the tank truck is a hollow metal container, which is used to hold the transported liquid inside, and in order to avoid excessive pressure in the tank , usually the liquid in the tank will not be full, and it will inev...

AI Technical Summary

Problems solved by technology

The metal tank body is directly fixed on the bottom frame; this structure makes the structure of the whole tank car very streamlined and compact, but there is a very big problem, that is, the liquid in the tank body will impact the inner wall of the front end of the tank body when the tank car is parked , resulting in severe impact, the longer the tank, the more obvious the impact, because the liquid in the tank can flow when parking, so the liquid in the front will continue to surge towards the front of the tank (driving direction), thus forming an impact force , it is easy to cause unstable parking, difficult braking, and even directly lead to rollover, especially when a tanker running at high speed encounters an emergency brake, the large amount of liquid in the tank may cause the entire tanker to overturn due to the impact force generated by inertia
