High-strength light high-speed rail tunnel cable supporting frame aluminum profile and preparation process thereof

Abstract

The invention discloses a high-strength light high-speed rail tunnel cable supporting frame aluminum profile and a preparation process thereof. The high-strength light high-speed rail tunnel cable supporting frame aluminum profile comprises fixed blocks, connecting blocks and clamping mechanisms. The fixed blocks and the connecting blocks are spliced to form a semicircular structure matched with ahigh-speed rail tunnel. The clamping mechanisms comprise clamping plates which are symmetrically arranged; connecting plates are fixedly connected to the connecting blocks; rotating plates are symmetrically and rotationally connected to the connecting plates; one end of each rotating plate is fixedly connected to an outer side wall of the corresponding clamping plate; the other end of the rotating plate is rotationally connected with a pushing plate; a lower surface of the pushing plate is fixedly connected with a first threaded rod; one end of the first threaded rod penetrates through the connecting plate and extends to a position below a connecting plate, and fixing nuts are arranged on an upper side and a lower side of the connecting plate. The fixed blocks and the connecting blocks are spliced to form the semicircular structure matched with the high-speed rail tunnel, and therefore the fixed blocks and the connecting blocks are installed in the high-speed rail tunnel, and the installation of a cable is facilitated.

Description

technical field [0001] The invention relates to the technical field of high-speed rail tunnel cable installation, in particular to an aluminum profile of a high-strength and light-weight high-speed rail tunnel cable support frame and a preparation process thereof. Background technique [0002] The cable is usually a rope-like cable twisted by several or several groups of wires (at least two in each group). Each group of wires is insulated from each other and is often twisted around a center. Insulated covering layer, the cable has the characteristics of internal energization and external insulation. At present, cable brackets are widely used in the installation and fixing of cables and cables in aviation, railway and other industries. fixed. [0003] However, the existing aluminum profiles of high-speed rail tunnel cable support frames are generally integrally formed and cannot be disassembled. Therefore, when the bracket is not used, it still occupies a large space and is ...

Problems solved by technology

[0003] However, the existing aluminum profiles of high-speed rail tunnel cable support frames are generally integrally formed and cannot be disassembled. Therefore, when the bracket is not used, it still occupies a large space and is inconvenient to store. The semicircle does not match, so it is inconvenient to fix it in the high-speed rail tunnel, which brings inconvenience to the staff to fix the support frame in the high-speed rail tunnel
