Cable pipeline fixing device

The invention relates to the technical field of building mechanical and electrical installation, in particular to a cable pipeline fixing device which comprises a corner supporting pipe assembly, and the corner supporting pipe assembly comprises a first supporting pipe body assembly, a second supporting pipe body assembly, a supporting regulation and control assembly and a stable connecting assembly. A corner of a cable pipeline is stably supported mainly through an arranged corner supporting pipe assembly, namely, the cable pipelines on the two sides of the corner supporting pipe assembly are stably supported; the first supporting pipe body assembly and the second supporting pipe body assembly form a supporting bent pipe, the supporting bent pipe is divided into two parts to be spliced, on one hand, the stable connecting assemblies are used in a matched mode, installation is stable, and meanwhile follow-up disassembly and maintenance work is facilitated; in addition, through matched use of the arranged suppo
