D-shaped portable beam adjustable positioning fastener support

The invention discloses a D-shaped portable beam adjustable positioning fastener support. The central axis of a positioning bolt deviates from the central axis of a mounting hole, and an annular eccentric clearance is formed between the positioning bolt and a locking press block. The D-shaped portable beam adjustable positioning fastener support is characterized in that a cylindrical eccentric washer is arranged between the positioning bolt and the mounting hole and inserted into the annular eccentric clearance, the whole inner wall of the eccentric washer is close to the outer wall of the positioning bolt, and the whole outer wall of the eccentric washer is close to the inner wall of the locking press block. The D-shaped portable beam adjustable positioning fastener support has the advantages that the clearance between the positioning bolt and the inner wall of the locking press block mounting hole is eliminated by inserting the eccentric washer, the movement amount of the locking press block is eliminated as the positioning bolt is fixed, a mounted portable beam fastening plate cannot move, reliability of a rail is ensured, and safety of a railway is improved.
