Description

Technical Field

[0001] The utility model relates to the technical field of railway equipment, in particular to a full-covering externally locked turnout traction point snow prevention device. Background Art

[0002] A turnout is a line connection device that allows locomotives and vehicles to transfer from one track to another. It is also one of the weak links of the track and is usually laid in large quantities at stations and marshaling yards. With a turnout, the line's capacity can be fully utilized. Even for a single-track railway, laying a turnout and building a fork line that is greater than the length of the train can allow trains to run in opposite directions. Turnouts play an important role on railway lines. Due to the characteristics of turnouts, such as large number, complex structure, short service life, limited train speed, low driving safety, and large maintenance and repair investment, turnouts, curves, and joints are collectively known as the three weak links of the track. When the train changes tracks, the turnout needs to be turned. In rainy and snowy weather, a large amount of snow gathers on the turnout, and the rain and snow form hard blocks, which will hinder the turnout. At this time, turning the turnout will damage the turnout, greatly reducing the service life of the railway turnout. At the same time, it has a greater impact on the operation of the locomotive; therefore, designing a fully covered external locking turnout traction point snow protection device is an urgent problem that technicians in the relevant field need to solve. Utility Model Content

[0004] The advantages of the utility model compared with the prior art are: the utility model can provide a protective structure between the point rails and the side protective structure to fully cover the railway turnout and prevent snow when the point rail is moved, thereby preventing rain and snow from falling on the railway turnout and the outer locking device of the turnout, effectively protecting the railway turnout, and extending the service life of the railway turnout. At the same time, it is convenient to open, close and assemble, and is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS
