Aluminum alloy bridge stand

Abstract

The invention discloses an aluminum alloy bridge stand, mainly comprising a two-side cross-arms which is installed on a left side plate and a right side plate through connection screws, and is composed of an outer cylinder, limiting screws and an inner cylinder; four sides of the inner cylinder are all provided with rectangular bosses, and four sides of the outer cylinder inner wall are all provided with rectangular grooves; the inner cylinder is installed in the outer cylinder; four sides of the outer cylinder outer wall are all provided with installing holes; limiting screws are installed in the installing holes of the outer cylinder. An intermediate cross-arm is composed of a left sleeve, a right sleeve, right limiting screws and left limiting screws; four sides of the right sleeve are all provided with rectangular bosses; four sides of the left sleeve inner wall are all provided with rectangular grooves; the right sleeve is installed in the left sleeve; four sides of the left sleeve outer wall close to the left side and the right side are all provided with installing holes; the left limiting screws are installed in the installing holes of the left sleeve close to the left side, and the right limiting screws are installed in the installing holes of the left sleeve close to the right side; the intermediate cross-arm is fixedly mounted on the two-side cross-arm.

Description

technical field [0001] The invention relates to the technical field of power transmission and distribution equipment, in particular to an aluminum alloy bridge frame. Background technique [0002] The bridge devices used in power or communication cable routing and other projects are generally dared to be spliced ​​into sections in the factory to be spliced ​​on site, and each type is fixed in one specification and size, so the processing cycle is long, and the installation of auxiliary facilities is more. Labor High strength, with continuous improvement, although an aluminum alloy cable tray with adjustable side plates has appeared, its structural design is unreasonable, which increases the overall weight, especially the bottom plate has low strength and is easy to deform, so it cannot quickly adapt to the site Changing environments and conditions. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an aluminum allo...
