Description

A cable positioning device suitable for cable tray

【Technical field】

The utility model relates to a cable bridge, in particular to a cable positioning device suitable for the cable bridge.

【Background technique】

It is known that the cable tray is mainly used for laying cables on the building, and the cable can be closed on the building through the cable tray. format and other structures; cable trays use brackets, brackets and installation accessories where conditions permit, and use cable trays to avoid accidents from being exposed to cables and being directly contacted by other objects; cable trays can be installed in bridges and culverts. To reduce secondary damage to buildings without cable trenches, "cutting grooves on buildings to hide cables" also has aesthetic effects; but the existing cable bridge structures suitable for installation at the bottom of bridges and at the top of culverts are channel steel, By fixing the channel-shaped cable tray on the bottom of the bridge or the top of the culvert, the steel plates on both sides of the connection wall are welded at intervals at the lower opening. When in use, the cables are inserted into the channel-shaped cable tray on the upper part of the steel plate, and then use the plug-in bottom plate Close the lower opening. The use of this structure must disconnect the cable close to the bridge or culvert, and then connect the disconnected part of the cable after the construction is completed. In the operation of loading the old cable into the cable bridge, it is necessary to cut off the power. So the construction steps are cumbersome.
