Folding type brake column

Abstract

The invention discloses a folding type brake column which comprises a brake column upper portion, a brake column lower portion and an O-type hanging ring. The rear portion of the brake column upper portion and the rear portion of the brake column lower portion are hinged through a rotary device. The brake column upper portion can rotate at 180 degrees around the rotary device. The front portion of the brake column upper portion and the front portion of the brake column lower portion are fixed through a fixing device. The O-type hanging ring is fixed on the brake column upper portion through a bolt and a nut. The rotary device comprises a hinge and a straight pin. The two ends of the hinge are welded on the brake column upper portion and the brake column lower portion respectively. The fixing device comprises a connecting piece and a hinge pin. The lower end of the connecting piece is hinged to a hinge pin of the brake column lower portion. The upper end of the connecting piece is connected and fixed with the brake column upper portion through an installation hole, a bolt and a nut. Compared with the prior art, the folding type brake column can be disassembled and assembled only through the disassembly of the O-type hanging ring, the height of the folding type brake column can be reduced, operation is simple, the folding type brake column can be reused, and the transportation cost is greatly saved.

Description

technical field [0001] The invention relates to a brake column, which belongs to the field of high voltage transformer transportation. Background technique [0002] In the field of high-voltage transformer transportation, after the transformer is fixed on the packaging frame and hoisted to the transport vehicle, it is necessary to connect and fix the brake column on the packaging frame with the transport vehicle through a knife chain, so that the packaging frame and the transport vehicle are integrated. When recycling the packaging rack, in order to save transportation costs, it is necessary to transport multiple packaging racks at a time. Due to the influence of the height of the brake column, the brake column can only be cut from a certain height, and then several packaging racks are stacked up. This method Not only is it time-consuming and labor-intensive, because the upper part of the brake column is cut off, it must be repaired again when it is reused, and the cut-off p...

[0002] In the field of high-voltage transformer transportation, after the transformer is fixed on the packaging frame and hoisted to the transport vehicle, it is necessary to connect and fix the brake column on the packaging frame with the transport vehicle through a knife chain, so that the packaging frame and the transport vehicle are integrated. When recycling the packaging rack, in order to save transportation costs, it is necessary to transport multiple packaging racks at a time. Due to the influence of the height of the brake column, the brake column can only be cut from a certain height, and then several packaging racks are stacked up. This method Not only time-consuming but also labor-intensive. Because the upper part of the brake column is cut off, it must be repaired again when it is reused, and the cut-off part is easily lost, resulting in time-consuming and laborious reuse, and the reuse effect is not ideal.
