Problems solved by technology
[0005] The positioning support is fixed on the beam by bolts. One side of the adjustable buckle plate is pressed on the positioning support, and the other side of the adjustable buckle plate is pressed on the rail. In the actual installation process, due to the deformation of the beam and the positioning support The screw holes between the beam and the beam do not match and other factors cause the end of the positioning support close to the rail to be warped, so that one side of the adjustable buckle is suspended in the air, and the adjustable buckle cannot press the lower end of the rail, which will also leave a gap for the railway. Security risks

Embodiment Construction
[0037] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0038] figure 1 Shown is the structural diagram of the prior art, because there is a gap 15 between the positioning bolt 3 and the mounting hole 8 of the locking press block 6, so that the beam buckle 5 cannot be close to the rail 16, and the beam buckle 5 and the rail There is a gap 17 between the 16, so that the rails are easy to loosen; the invention provides a D-shaped beam adjustable positioning fastener bracket, including a positioning support 2 buckled on the beam 1, a beam buckle plate assembly, a positioning bolt 3 and Nut 4, just beam buckle plate assembly comprises just beam buckle 5 and locking pressure block 6, and the upper surface of just beam buckle 5 is provided with the first tooth structure, and the lower surface of locking pressure block 6 is provided with the second Toothed structure, the first toothed structure and the ...

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.
Description
technical field [0001] The invention relates to an accessory accessory of a railway track, in particular to a D-shaped beam adjustable positioning fastener bracket. Background technique [0002] When laying temporary rails, the rails are fastened to the crossbeams with a beam fastening system. The construction convenience beam rail fastener with the authorization date of 2010.05.12 and the application number of 200920034127.X is composed of the positioning support of the gusset plate, the side rib plate of the beam, the adjustable gusset plate, the stop washer and the positioning bolt, and the gusset plate is positioned The support is directly connected to the side rib of the beam, and the adjustable buckle is connected to the side rib of the beam through a positioning bolt and a stop washer. An insulating angle is arranged between the buckle plate and the lower part of the steel rail. The technical proposal solves the problems of weak connection between traditional rail ...
