Problems solved by technology

The breakage of the elastic strip is inevitable, and it is acceptable to keep the breakage rate at a certain low rate. However, after the elastic strip breaks, the unconstrained part may splash out, hitting vehicle equipment and even pedestrians, causing vehicle damage or even endangering safety.
At present, there is no effective way to limit the safety accidents caused by broken elastic bars
In addition, according to the technical requirements of the railway system, the fastener system generally needs to meet certain insulation performance requirements. Currently, there are no insulation measures and structures on the elastic strips.

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] refer to figure 1 , Figure 5 , the anti-splash structure of the clip system of the fastener system of the present invention includes a clip body 1, the annular section of the clip body 1 is covered with a flexible protective sleeve 2, and the flexible protective sleeve 2 forms a tight fit with the clip body 1 connect. Even if the clip body 1 breaks, the flexible protective cover 2 wrapped on its outer surface will not break, and the broken clip body 1 is constrained by the flexible protective cover 2, effectively solving the problem of splashing or popping up after the clip body breaks . Since the flexible protective sleeve 2 effectively isolates the rail from the spring bar body 1, the insulation performance of the fastener system can be increased. The invention has the characteristics of simple structure, good splashing effect of the bulle...

Abstract

The invention discloses an elastic strip post-breakage splashing preventive structure for a fastener system. The elastic strip post-breakage splashing preventive structure comprises an elastic strip body, and is characterized in that a flexible protective sleeve covers and wraps the annular cross section of the elastic strip body and is connected with the elastic strip body in a tight fit manner;the flexible protective sleeve is arranged along the total length of the elastic strip body or is arranged on bent sections, which are vulnerable to breakage, of the elastic strip body. The elastic strip post-breakage splashing preventive structure has the advantages that an elastic strip can be effectively prevented from splashing after the elastic strip is broken under abnormal conditions, and the insulation performance of the fastener system under normal use conditions can be improved.

Description

technical field [0001] The invention relates to a railway fastening system, in particular to an anti-splash structure for elastic strips of the fastening system after being broken. Background technique [0002] The fastener system is an important part of the wheel-rail railway system. Its function is to buckle and fix the rail on the sleeper or track slab, maintain the gauge and prevent the vertical and horizontal movement of the rail, transfer the vehicle load to the substructure, and provide certain Elasticity and deformation coordination ability. [0003] With the development of railway construction, the vast majority of railways have adopted elastic fastener systems, which are generally composed of spring bars, backing plates, anchor bolts, spring washers, elastic backing plates and other components. The elastic strip provides elastic fastening pressure for the fastener system and is a key component of the fastener system. At present, the types of clips used mainly inc...
