Description

Technical Field

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

[0002] Rails are the main components of railway tracks. Their function is to guide the wheels of locomotives and vehicles forward, bear the huge pressure of the wheels, and transmit it to the sleepers. Rails must provide a continuous, smooth and least resistant rolling surface for the wheels. And when the train is running, one side is connected to the soft cross-specific multi-track contact suspension, which is suspended on the pillars on both sides of the line through transverse wires for insulation treatment. In electrified railways or automatic block sections, rails can also be used as track circuits. The rails of the prior art need to be installed and fixed during installation.

[0003] However, the existing rail fastening device has the following disadvantages:

[0004] (1) The existing rail fastening device has a weak function of facilitating replacement. When the rail needs to be replaced, the existing fastening device uses multiple bolts to fix it to the surface of the base at the bottom of the rail, and the device connected to the rail on one side is installed too tightly, which makes it difficult to remove during disassembly.

[0005] (2) The existing rail fastening device has a weak function of fixing the rail. When the rail is in use, the fixing plate on one side is usually placed on the inner wall of the rail and fastened with bolts. After long-term use, the rail connected on one side of the bolt vibrates, which may cause the bolt to loosen. Utility Model Content
