The invention relates to the technical field of cable supports, and discloses an
electric power tunnel cable support, multiple groups of cable supports are arranged along the trend of a tunnel, the tunnel is formed by splicing a plurality of annular support plates, two sides of the inner wall of each annular support plate are provided with a plurality of embedded grooves, and the
electric power tunnel cable support comprises two racks, a cross arm and an adjusting mechanism; opening and closing of the
tail end of the supporting arm are controlled through the adjusting mechanism, and rapid sleeving connection or separation of the support and the arc-shaped screw rod can be achieved. Complex
punching or
welding operation does not need to be conducted on the
tunnel wall, the efficiency of installation, adjustment and later maintenance of the support is greatly improved, and the support is particularly suitable for being operated in the tunnel environment with the limited space. The embedded groove in the original annular supporting plate of the tunnel is matched and fixed with the arc-shaped screw, the support does not need to be additionally provided with a large number of anchoring points, the integrity of the tunnel structure is kept, the installation position of the support can be flexibly adjusted in the trend of the tunnel, and the cable laying requirements of different sections are met.
