The utility model provides a three-barrel tank body and a semi-trailer of a liquid tank semi-trailer, whose structural characteristics are as follows: the front head, the front barrel body, the middle section variable cross-section long barrel body, the rear section barrel body and the rear head are connected sequentially from left to right; the front section barrel body and the rear section barrel body are straight barrels with openings at both ends, and the two ends of the middle section variable cross-section long barrel body are opened, and the section of the middle section variable cross-section long barrel body is reduced The larger opening section is the big end, and the smaller end is the other side. The two ends of the front section cylinder are fixed with the small end of the front head and the middle section variable cross-section long cylinder respectively, and the two ends of the back section cylinder are fixed with the big end of the back head and the middle section variable cross-section long cylinder respectively. The utility model has the advantages that under the same tank capacity, the tank size can be effectively shortened, the plate can be saved, the weight of the car body can be reduced, the arrangement of the wave-proof plate inside the cylinder body can be conveniently arranged, the liquid impact in the tank can be reduced, and the unloading speed can be accelerated, and the liquid residue can be reduced.

一种液罐半挂车的三节筒罐体及其半挂车
本技术涉及液体罐式运输半挂车,具体是一种液罐半挂车的三节筒罐体。
技术介绍
目前市场上液罐半挂车罐体结构主要有2种:一节直筒罐体结构;常规三节变截筒罐体结构。一节直筒罐体结构工艺简单,防波板布置方便,但存在重心高、重量重、卸料慢的缺点;常规三节变截筒罐体结构重心低、重量轻,但存在罐内防波板布置困难等缺点。
技术实现思路
本技术目的是提供了一种液罐半挂车的三节筒罐体结构,既能降低罐体重心高度,减轻自重,加快卸料速度,减少液体残余,还可以方便罐内防波板的布置,优化车体结构。本技术解决技术问题提供如下方案:一种液罐半挂车的三节筒罐体,包括罐体,其特征在于:所述罐体从左到右顺次相连接的前封头、前节筒体、中节变截面长筒体、后节筒体和后封头,所述前节筒体和后节筒体都是两端开口的直筒体,所述中节变截面长筒体为两端开口,开口截面较大的为大端,反之为小端,所述前节筒体两端分别与前封头和中节变截面长筒体的小端固定,后节筒体两端分别与后封头和中节变截面长筒体的大端固定。所述前节筒体和后节筒体的纵截面为矩形,中节筒体纵截面为直角梯形状,所有筒节的顶部齐平,所述中节变截面长筒体的长度为一设定长度,及其开口两端纵截面高度具有落差。所述中节变截面长筒体和后节筒体的顶部均设置有人孔。所述半挂车体上安装有包含权利要求1至3中任一项所述的液罐半挂车的三节筒罐体。本技术与上述常规液罐半挂车罐体结构相比,本技术综合了常规直筒罐体结构和常规三节变截筒罐体结构两者的优点,避免了两者的缺点,形成了新型三节筒罐体结构。其中,中节变截面长筒体设计可有效降低了罐体重心高度,加快 ...
