The invention discloses a pipe gallery support facilitating steady installation. The pipe gallery support facilitating steady installation comprises bases, the surface of each base is fixedly connected with a vertical supporting post, a first sliding groove is formed in the surface of each vertical supporting post, a plate supporting block is in sliding connection with the inner wall of each firstsliding groove, and the surfaces of the plate supporting blocks are fixedly connected with a transverse supporting plate. A second sliding groove is formed in the surface of each vertical supportingpost, and fixing rods are in sliding connection with the inner walls of the second sliding grooves. According to the pipe gallery support facilitating steady installation, by rotating pressing rods onthe inner walls of pressing holes, the pressing rods drive pressing heads to be squeezed into pressing grooves, the pressing heads are in butt joint with second limiting blocks, two first limiting blocks are propped open and slid into the second sliding grooves to be in sliding connection with the fixing rods through the pressing heads, and the effect that the fixing rods are steadied and prevented from sliding is achieved, so that the problems that common pipeline supports are relatively simple in structure, are not steady enough in installation, and have potential safety hazards to a certain extent in use are solved.
