Abstract

The invention provides an inflammable liquid tank type transportation semitrailer, and relates to the technical field of semitrailers, the inflammable liquid tank type transportation semitrailer comprises a semitrailer body; the outer tank body is fixedly mounted on the vehicle body; the inner tank body is arranged in the outer tank body, the inner tank body can slide in the transverse direction of the outer tank body, a liquid storage cavity is formed in the inner tank body, a liquid pumping cavity is formed in the middle of the inner tank body, a plurality of steel plates are arranged in the liquid storage cavity at intervals, and flowing channels are formed in the steel plates; one end of the liquid pumping device is communicated with the liquid storage cavity; the inner tank body continues to slide by a certain distance towards the driving direction relative to the outer tank body, the inner tank body moves rightwards relative to the piston head, negative pressure is formed in the liquid pumping cavity, liquid in the liquid storage cavity is pumped into the liquid pumping cavity through the liquid pumping device, the inner tank body compresses the elastic piece, the elastic piece and the piston head can provide resistance, and the liquid in the liquid storage cavity is pumped into the liquid pumping cavity. The buffer effect on the inner tank body is achieved, and inertial impact caused by emergency braking is counteracted.

Description

technical field

[0001] The invention relates to the technical field of semi-trailers, in particular to a tank-type transport semi-trailer for flammable liquids. Background technique

[0002] A semi-trailer is a trailer whose axle is placed behind the vehicle's center of gravity (when the vehicle is evenly loaded) and is equipped with a hitch that transmits horizontal and vertical forces to the tractor. Semi-trailers are generally three-axle semi-trailers, and their types are divided into 11-meter warehouse semi-trailers, 13-meter warehouse semi-trailers, and low-bed semi-trailers. It is a heavy-duty transport vehicle connected to the semi-trailer head through the traction pin.

[0003] For semi-trailers transporting flammable liquids, during transportation, when the driver brakes suddenly, it is easy to cause the liquid in the tank to flow, which increases the impact of the liquid on the tank. Inertial shock caused by braking. Contents of the invention
