[0002] The production process of aluminum alloy rectangular extruded tube is a kind of semi-trailer. The side panels of the traditional aluminum alloy rectangular extruded tube production process are integral. The integral side panel is conducive to the installation of the side panel. During operation, high-speed airflow is easy to form on both sides of the side plate, which will generate high pressure on the side plate, causing damage to the side plate or vibration, causing the grid to fall off, causing accidents on the highway and affecting driving safety

Embodiment Construction
[0009] Such as figure 1 and figure 2 As shown, the aluminum alloy rectangular extruded pipe production process of the present invention includes two parallel longitudinal beams 1, and four crossbeams 2 perpendicular to the two longitudinal beams 1 are connected in the middle of the longitudinal beams 1, and the crossbeams 2 and the longitudinal beams 1 form a semi-trailer For the vehicle underframe, six columns 3 are welded on the upper end of each crossbeam 2, the columns 3 are perpendicular to the upper end surface of the vehicle underframe, pin holes are arranged on the outer circumference of the columns 3, and the beams 2 or longitudinal columns between every two adjacent columns 3 Four hinged tubes 5 are welded on the upper end of the beam 1, and a sub-grid plate 4 is arranged between two adjacent columns 3, and four hinge columns are arranged on the lower end of the sub-grid plate 4, and the sub-grid plate 4 passes through the hinge columns through the hinge columns. T...

The invention relates to a transportation tool, aims to provide a semi-trailer which is simple in structure, safe and anti-shaking, and discloses a rectangular aluminum alloy extruded tube production process. The rectangular aluminum alloy extruded tube production process comprises two parallel longitudinal beams, wherein four cross beams perpendicular to the two longitudinal beams are connected in the middle of the longitudinal beams. A semi-trailer bottom frame is composed of the cross beams and the longitudinal beams. The upper end surface of each cross beam is welded with six stand columns which are perpendicular to the upper end surface of the semi-trailer bottom frame, wherein pin holes are arranged at the upper end of the circumference of the stand columns. The upper end surfaces of cross beams or longitudinal beams between every two neighboring stand columns are provided with four reaming pipes in a welded mode. A grid separation plate is arranged between every two neighboring stand columns. Four hinged columns are arranged on the lower end surfaces of the separation grid plate, and the grid separation plates penetrate through a reaming pipe and are hinged on the longitudinal beams or the cross beams through the hinged columns. Bolt columns are placed at the upper ends of the grid separation plate and correspond to positions of the pin holes. Because the grid separation plates are adopted, impact of shaking of side plates of the semi-trailer on car safe traveling is effectively avoided.
Description
technical field [0001] The invention relates to a transportation tool, in particular to a semi-trailer. Background technique [0002] The production process of aluminum alloy rectangular extruded tube is a kind of semi-trailer. The side panels of the traditional aluminum alloy rectangular extruded tube production process are integral. The integral side panel is conducive to the installation of the side panel. During operation, high-speed airflow is easy to form on both sides of the side plate, which will generate high pressure on the side plate, causing damage or vibration of the side plate, causing the grid to fall off, causing accidents on the expressway and affecting driving safety. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a semi-trailer with simple structure, safety and anti-vibration. [0004] The production process of the aluminum alloy rectangular extruded pipe of the present invention comprises two parall...
