[0050] The embedded stud plate 4 is used to cooperate with the pulley bracket 3 and is fixedly connected using threads, so that the pulley bracket 3 and the top protective cover body 1 become a whole.

[0051] In one embodiment, please refer to Figure 1 The pulley 5 is also provided with an anti-drop nut 15 in the rotating shaft direction to limit the horizontal movement of the pulley 5 in the supporting guide rail 6. The anti-drop nut 15 further limits the top protective cover to prevent the top protective cover from detaching from the top of the locomotive when sliding and causing a dangerous accident.

[0052] like Figure 1 As shown, in one embodiment, a plurality of lifting rings 2 are provided at symmetrical positions on the top of the top protective cover body 1 to provide stable lifting force points for the installation of the top protective cover, thereby improving the safety and reliability of the top protective cover during the installation process.

[0053] Figure 2A is a top view of a top protective cover according to an embodiment of the present invention; Figure 2B FIG. 4 is an isometric view of a top protective cover according to an embodiment of the present invention.

[0054] Please refer to Figure 2A , 2BThe lower part of the support rail 6 is installed and fixed on both sides above the roof of the rail vehicle along the length direction of the rail vehicle through multiple rail support bases 16. The installation position of the support rail 6 cooperates with the position of the pulley 5 on the top protective cover body 1 to provide guidance and support for the pulley 5.

[0055] The guide rail support base 16 is connected to the upper bracket of the vehicle body by bolts to ensure that the support guide rail 6 is firmly and reliably connected to the vehicle body.
