[0036] The bottom of the support main body 1 is provided with a plurality of guide rails 2 at equal intervals, and each guide rail 2 is arranged along the width direction of the support main body 1. The guide rail 2 can adopt any track structure that can realize the sliding of the sliding module 3, but when arranging the guide rail 2, the opening of the track thereof should face downward, and the spacing between the adjacent two guide rails 2 is determined according to the rigidity and allowable deflection of the parallel pipeline pipe. In the embodiment, the guide rail 2 is welded and fixed on the lower surface of the support main body 1, the guide rail 2 is made of a C-shaped steel with a thickness of 3 mm, and the notch of the C-shaped steel faces downward.
