Sand blasting machine and sand blasting system provided therewith

Abstract

The invention discloses a sand blasting machine and a sand blasting system provided therewith, which can be used for the container chassis welding line to blast sand. The sand blasting machine comprises two first rails, a truss, a cargo carrying platform and at least one driving mechanism, wherein the first rails are erected in parallel; the truss is hung above the first rails; the cargo carrying platform is arranged on the first rails; the driving mechanism drives the cargo carrying platform to slide back and forth on the first rails; two sides of the truss, which correspond to the width direction of the cargo carrying platform, are respectively provided with at least one upper sand box; the position corresponding to each upper sand box below the first rails is respectively provided with two lower sand boxes so as to make the container arranged on the cargo carrying platform and dragged back and forth by the cargo carrying platform for realizing scanning-type sand blasting via an upper sand gun and a lower sand gun. The sand blasting system realizes full-automatic sand blasting of container chassis C-type welding lines, can effectively solve influence on sand blasting quality by illumination or human factors for R-angle welding lines.

Description

technical field [0001] The invention relates to a sandblasting machine and a sandblasting system, in particular to a sandblasting machine and a sandblasting system for sandblasting the weld seam of a container bottom frame. Background technique [0002] Such as figure 1 As shown, the container chassis 1 generally includes: two longitudinal beams 11 located on both longitudinal sides of the container and a plurality of cross beams 12 located between the two longitudinal beams 11 and connected to both ends of the longitudinal beams 11. The cross-section of the cross beams 12 is C-shaped or I-shaped, including the upper wing 121, the lower wing 122 and the web 123 connected between the upper and lower wing 121, 122, so the inner and outer sides of the position where the beam 12 and the longitudinal beam 11 are connected C-shaped welds 13 are formed respectively. The C-shaped welds 13 form an upper R angle 131 near the upper wing plate 121 , and the C-shaped welds 13 form a low...

AI Technical Summary

Problems solved by technology

Because sand blasting is a highly polluting operation, and the steel grit splashes, the illumination in the pit is insufficient, there is a lot of dust, and the working environment is very harsh

At the same time, because the operator needs to look up at the sandblasting, the work intensity is high, the sandblasting effect is poor, and the sandblasting density at the upper and lower R angles 131 and 132 of the C-shaped weld 13 is not enough
