Description

Technical Field

[0001] This utility model belongs to the technical field of short sleeper vibration damping fasteners, specifically an improved short sleeper vibration damping fastener. Background Technology

[0002] Railway tracks, also known as rails, are mainly used on railways and work in conjunction with switches to allow trains to travel without turning. A railway track typically consists of two parallel steel rails fixed to sleepers. Below the sleepers is the ballast, secured by railway accessories such as rail braces, fasteners, rail clamps, rail clips, elastic clips, and railway spikes. Made of steel, railway tracks can withstand greater weight than other materials. Sleepers, also called rail sleepers, are used to distribute the weight and pressure on the rails, maintaining a fixed track gauge.

[0003] Meanwhile, a track damping fastener with good stability, with application number CN202223446479.0, includes an elastic fastener as the main running part, damping blocks installed inside the elastic fastener, a strong spring installed between the damping blocks, a limiting arc plate installed at the top of the elastic fastener, a bolt passing through the top right side of the limiting arc plate, a fixing nut installed at the bottom of the bolt, and a locking block installed at the bottom of the fixing nut.

[0004] However, the following problems were found in the implementation of the relevant technology: it achieves the purpose of shock absorption through strong springs and shock absorbers, but the middle of the strong spring is indeed lacking a connecting structure, resulting in a lack of support in the middle of the strong spring. If the vibration force is strong, the strong spring is prone to tilting, thereby losing its vertical support force and affecting the vibration reduction effect. Utility Model Content

[0007] The surface of the mounting component is connected to the surface of the rail body;

[0008] The surfaces of both vibration damping components are connected to the surface of the rail body.

[0009] Preferably, the mounting assembly includes a mounting ring disposed on the surface of the rail body, and two mounting plates are connected to the surface of the mounting ring, with three fastening bolts threaded onto the surfaces of both mounting plates.

[0010] Preferably, both vibration damping components include vibration damping buckles, the surfaces of both vibration damping buckles are connected to the inner side of the mounting ring, the inner sides of both vibration damping buckles are connected to silicone pads, the inner sides of both silicone pads are connected to reinforcing rods, the two ends of both reinforcing rods are connected to vibration damping rods, and the outer sides of all four vibration damping rods are fitted with composite thickened springs.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model connects the support plate with the corresponding composite thickened spring, which helps to reduce the vibration generated by the rail body when it is under pressure due to the connection effect of the support plate. The damping rods and composite thickened springs arranged symmetrically on both sides can further distribute the pressure on the rail body and play a role in shock absorption. Moreover, the composite thickened spring is sleeved on the corresponding damping rod, which can provide good support for the middle part of the composite thickened spring and prevent the composite thickened spring from tilting, thereby better absorbing the vibration of the rail body.

[0018] 2.
