Problems solved by technology
[0006] When the fastener structure involved in the above two patents is in operation, the rails are torsionally and vertically elastically deformed by the running of the vehicle, and produce resistance to the fastener along the laying direction of the rail, forcing the bracket to move vertically, torsion and Moving along the direction of the rail, this kind of fastener does not constrain the bracket very well, and cannot effectively control the movement of the bracket

Embodiment Construction
[0033] The present invention is described in conjunction with accompanying drawing and specific embodiment:
[0034] Such as figure 1 As shown, in the suspension rail damping fastener installed in the chute type, a group of non-metallic elastic bodies 2 are arranged symmetrically on both sides of the rail 1, and the material of the non-metallic elastic body can be rubber, or plastic, or rubber Plastic blend, its internal density can be uniform or uneven; the end face radian of the non-metallic elastomer 2 matches the radian of the rail waist, and the contact surface between the non-metallic elastomer and the rail can be smooth or have grooves structure, stud structure, groove structure, conical structure; several sockets or grooves are provided on the bottom surface of the non-metallic elastic body 2, so as to connect the non-metallic elastic body 2 with the lateral bracket 3; the non-metallic elastic body is fixed on the side The way on the bracket can be plug-in type, can b...

The invention belongs to the field of rail vibration reduction and noise reduction, and provides a chute-mounted suspended steel rail vibration reduction fastener. A structure for limiting a lateral bracket (3) is arranged at the joint position of a fastener bottom plate (4) and the lateral bracket (3), and the limiting structure is provided with at least one limiting surface I (6) for limiting the lateral bracket (3) to move in the laying direction of a steel rail and at least one limiting surface II (14) for limiting the lateral bracket (3) to move vertically; and a space for allowing the lateral bracket (3) to horizontally move in the direction vertical to the laying direction of the steel rail (1) is formed between the limiting surface I (6) and the limiting surface II (14). Through the fastener, movement of the lateral bracket (3) in the vertical direction and the laying direction of the steel rail (1) can be effectively controlled, torsion of the lateral bracket (3) due to torsion of the steel rail (1) can be effectively controlled, the stability of the lateral bracket (3) structure is effectively enhanced, and the safety of a vehicle is ensured.
Description
technical field [0001] The invention belongs to the field of rail vibration and noise reduction, and mainly relates to a chute-mounted suspension rail vibration-damping fastener, which is especially suitable for the laying of new lines and the reconstruction of old lines for urban subways, light rails, intercity railways, and high-speed railway traffic. Background technique [0002] In recent years, my country's subway, light rail and other urban rail transit systems have developed rapidly, effectively alleviating the tension in urban traffic, but how to control the vibration and noise pollution generated during the operation of rail transit has become an urgent problem to be solved. The application of vibration and noise reduction fasteners is an effective treatment method. The traditional fastener system is to install one or more layers of low-rigidity elastic backing plates under the rails, the upper part is fastened by elastic strips to the rail foot, and the lower part ...
