Problems solved by technology

This kind of supporting member is most widely used in the power supply department, the power transmission system for centralized power supply and distribution of industrial and mining enterprises, hotels, and comprehensive office facilities, and wired telecommunications. Usually, cable trays are installed in advance, and then the lines are laid. As more and more lines need to be laid, the capacity of the originally installed cable tray may not be enough to lay more lines in it, so it is necessary to install another cable tray, which is not only time-consuming and laborious, but also improves economic cost

Abstract

The invention discloses a stepped cable bridge with expansion structure. The cable bridge includes two side plates arranged in parallel and a plurality of beams arranged between the two side plates in parallel. The bottom ends of the two side plates are respectively hinged with A plurality of elongated connecting rods, the elongated connecting rods are arranged at the bottom of the beam, and the multiple elongated connecting rods correspond to the multiple beams one by one, the other end of the elongated connecting rods is vertically provided with a fixed rod, the The fixed rod extends upwards through the through hole on the beam, and the upwardly extending part of the fixed rod is provided with pin holes along the direction of the beam, and two adjacent fixed rods on the beam pass through the holes on the two fixed rods through the fixed pins. The pin holes are connected, and the plurality of beams can move up and down. The present invention can expand the capacity of the cable bridge in use, is convenient for laying more lines, and can expand capacity according to needs at the same time, and has simple structure, convenient capacity expansion, and is suitable for practical use.

Description

technical field [0001] The invention relates to a stepped cable bridge, in particular to a stepped cable bridge with an expansion structure. Background technique [0002] The cable tray is mainly used for integrated wiring such as power supply supporting power transmission and wired telecommunication transmission, and a supporting member for laying cables. This kind of supporting member is most widely used in the power supply department, power transmission system for centralized power supply and distribution of industrial and mining enterprises, hotels, and comprehensive office facilities, and wired telecommunications. Usually, cable bridges are installed in advance, and then the lines are laid. As more and more lines need to be laid, the capacity of the originally installed cable tray may not be enough to lay more lines in it, so it is necessary to install another cable tray, which is not only time-consuming and laborious, but also improves economic cost.
