On-vehicle package box for large-diameter annular workpiece and ultra-large type grading ring package structure

Abstract

The invention discloses an on-vehicle package box for a large-diameter annular workpiece and an ultra-large type grading ring package structure. The on-vehicle package box for the large-diameter annular workpiece comprises a bottom plate, a box body enclosed by side plates on the periphery, and a cover plate arranged opposite to the box body; a bottom row component used for supporting the ground surface when the box body is placed vertically is fixed on the outer surface of a side plate on one side of the box body; a pair of cross arm wood beams which are arranged at intervals and are used for supporting an annular workpiece when the box body is placed horizontally are fixed on the inner plate surface of the bottom plate of the box body at least; at least one pair of compressing wood beams which are spatially perpendicular to the cross arm wood beams are arranged between two opposite side plates of the box body; and the cross arm wood beams are fixedly connected with the compressing wood beams through connecting bolts arranged at spatial intersection points of the cross arm wood beams and the compressing wood beams. The package box provided by the invention has a simple structure and is convenient to use; the bumping and scratching of an ultra-large type grading ring in transit are avoided effectively; the safe load and transport of the ultra-large type grading ring are ensured; the transportation cost is reduced; and the on-vehicle package box for the large-diameter annular workpiece and the ultra-large type grading ring package structure are applicable to the transportation of domestic width-limited or height-limited roads and narrow mountain roads.

Description

technical field [0001] The invention relates to a packing box, in particular to a packing box used for shipping a large-diameter annular workpiece and a packing structure using the packing box for shipping a super-large pressure equalizing ring. Background technique [0002] With the continuous improvement of the national grid construction requirements, the million-volt power transmission and transformation project has gradually become the focus of construction, and the voltage-grading ring equipped with the million-volt isolating switchgear is one of the important components. For DC 816kV isolating switchgear, the outer diameter of the equalizing ring equipped on this isolating switch reaches 3300mm. Most of the power plants are built in remote mountainous areas with narrow roads and poor road conditions, so the pressure equalizing ring is easily damaged during transportation, and it does not meet the management regulations for road safety transportation; and if the pressur...
