Abstract

A perpendicular suspension base device for an anti-bending pre-embedded groove channel is disclosed. The perpendicular suspension base device comprises a suspension base and a suspension screw rod, wherein the upper end surface of the suspension base is provided with bosses which can be embedded in the pre-embedded groove channel and mounting holes; each boss is positioned at the two sides of the corresponding mounting hole; the middle part of the suspension base is a horizontal suspension plate; the center of the horizontal suspension plate is provided with a suspension hole; the upper end opening of the suspension hole is tapered; the suspension base is mounted at the pre-embedded groove channel by T-shaped bolt assemblies running through the mounting holes; the suspension screw rod runs through the suspension hole from top to bottom; a tapered washer, a spherical washer and a locking nut are sequentially sleeved on the suspension screw rod; the screw head of the suspension screw rod is matched with the tapered upper end opening of the suspension hole through a spherical surface; the perpendicularity of the suspension screw rod is automatically adjusted; and the suspension screw rod is perpendicularly fixed on the horizontal suspension plate. The perpendicular suspension base device for the anti-bending pre-embedded groove channel is capable of improving the bending resistance of the pre-embedded groove channel along the longitudinal direction, automatically adjusting the perpendicularity of the suspension screw rod and ensuring the perpendicular installation of the suspension screw rod.

Description

Technical field [0001] The invention relates to the technical field of rail transit, in particular to a vertical suspension base device of an anti-bending type embedded channel. Background technique [0002] The overhead rigid suspension busbar power supply system is an important urban rail transit contact network power supply method, which has been widely used, and the vertical suspension base device is an important part of the entire rigid power supply system. In the prior art, the vertical suspension base device is either fixed on the top of the tunnel with expansion bolts, or installed with T-bolts through pre-buried channels. The use of expansion bolts has a large on-site installation workload and low installation reliability, and has been gradually replaced by the installation of embedded channels. [0003] Due to the limitation of the structure of the traditional vertical suspension base, the bending resistance of the embedded channel is not good; in addition, the suspensio...
