To provide a piping structure of a tank lorry which prevents a residual liquid from being left in a pump or in piping near the pump when a liquid inside the tank is discharged while securing a space for pipes extended from a bottom part in a tank.SOLUTION: A frame comprises: a pair of left and right girder members 5 having a square-shaped cross section, disposed along a longer direction of a chassis; and a beam member 8 disposed on front and rear ends of the girder member 5 along a width direction of the chassis. A circulation pipe 16 is inserted in an opening 11 formed in the girder member 5 below the tank. A first opening/closing valve 17 and a second opening/closing valve 18 are connected on both ends, and a three-way joint pipe 20 is connected in an intermediate part of the circulation pipe 16, A switching valve having a rotation axis perpendicular to the horizontal circulation pipe 16 is attached on the three-way joint pipe 20. An inflow pipe 14 inclining downward toward the pump 12 from the tank is connected to an inlet of the pump 12 via a flexible connection member, and an outlet of the pump 12 and a center opening of the three-way joint pipe 20 are connected by an outflow pipe 22.SELECTED DRAWING: Figure 2
【課題】タンクにおける底部から延設される配管類のスペースを確保しながら、タンク内の液体の排出時にポンプ或いはポンプ近傍の配管に残液が発生し難いタンクローリの配管構造を提供する。【解決手段】架台はシャーシの長手方向に沿って配設する左右一対の断面四角形状の桁部材5と、桁部材5の前後端にシャーシの幅方向に沿って配設する梁部材8とよりなり、タンクの下方にて桁部材5に形成される開口11に流通管16を挿通し、この流通管16の両端に第1開閉弁17および第2開閉弁18を、中間に三方継手管20を連結し、三方継手管20には水平な前記流通管16に対して垂直な回転軸を有する切換弁を装着し、タンクよりポンプ12に向かい下方に傾斜する流入管14を可撓性よりなる接続部材を介してポンプ12の入口に連結するとともに、ポンプ12の出口と前記三方継手管20の中央口とを流出管22により接続する。【選択図】図2
