Description

Technical Field

[0001] The utility model relates to the technical field of rail positioning, in particular to a rail positioning and fastening device. Background Art

[0002] During track installation, fasteners are used to secure the rails to the sleepers. These fasteners typically have a positioning function, ensuring accurate positioning of the rails during installation. Fasteners typically consist of bolts, nuts, washers, and gussets. Tightening the bolts presses the gussets tightly between the sleeper and the rail, achieving securement.

[0003] For example, a rail positioning and fastening device disclosed in the existing patent publication number CN215561563U includes a sleeper base; it also includes: a fixed base plate, which is connected to the left and right ends of the upper side of the sleeper base, and the fixed base plate is connected to the sleeper base through fish bolts. The two fixed base plates are symmetrically distributed on the upper end of the sleeper base, and the inner sides of the two are in contact with the bottom end of the rail. The two fixed base plates are fixed to the upper end of the sleeper base through multiple groups of fish bolts, thereby limiting the position of the rail and ensuring the stability of the placement of the rail. It also includes elastic buckles and pressing plates.

[0004] The aforementioned fastening device can position rails, but the rails are secured using elastic buckles and pressure plates. Due to vertical displacement of the rails, the elastic buckles may lose significant clamping force, and the pressure plates may become loose due to vibration. This can cause unnecessary movement of the rails during train travel, compromising track stability and safety. To address these issues, a rail positioning and fastening device has been proposed.
