[0021] like Figure 1 As shown, when the switch machine changes direction, it drives the locking rod 1 to move. The locking hook 2, which is in close contact with the switch rail, moves with the locking rod 1 and enters the locking frame 3. At this time, it is required that there is no snow accumulation in the locking hook groove, otherwise the switch rail and the main rail will not be in close contact, affecting the operation of the train. Therefore, in order to melt the snow in the locking hook groove, the locking frame 3 needs to be heated first, and then the heat is conducted from the locking rod 1 to the locking hook groove.

[0022] This implementation example Figure 2 As shown, it is applied to the existing locking frame 3.

[0023] This embodiment includes a cover 4, a heating element 5, and a copper sheet 6.

[0024] like Figure 3, 4 As shown, the cover 4 includes a main cover 4a and side covers 4b. The main cover 4a is a cubic box shape, and the size of the main cover 4a corresponds to the locking frame 3. The front and rear walls of the main cover 4a are provided with protruding strips 4c to form convex surfaces, and the protruding strips 4c fit against the upper part of the locking frame 3.

[0025] The side cover 4b is U-shaped, and there are two side covers 4b located on the left and right sides of the main cover 4a respectively. The side cover 4b is connected to the open end of the main cover 4a, and the size of the side cover 4b corresponds to the locking rod 1. In order to improve the strength, this embodiment also provides reinforcing ribs 4e at the bottom of the side cover 4b and at the side wall of the main cover 4a.

[0026] The cover 4 is installed from bottom to top on the locking frame 3, so that the main cover 4a covers the locking frame 3 and the side covers 4b covers the locking rod 1. Specifically, in this embodiment, the main cover 4a is provided with mounting holes 4f that penetrate the left and right side walls. The mounting holes 4f are opened at the corresponding bolt positions on the locking frame 3. When installing the locking frame 3, the bolts can be directly passed through the mounting holes 4f to fix the cover 4 onto the locking frame 3.

[0027] The heating element 5 is located at the bottom of one side cover 4b and extends to the bottom of the main cover 4a to the bottom of the other side cover 4b. The heating element 5 on the bottom surface of the main cover 4a extends along the front and rear inner side walls to the top of the protrusion 4c. When the protrusion 4c is attached to the upper part of the locking frame 3, the heating element 5 can also cover the upper part of the locking frame 3. The heating element 5 is attached to the inner wall of the cover 4 with high temperature resistant adhesive.

[0028] In this embodiment, the heating element 5 uses a graphene heating wire, and the graphene heating wire is covered with a Teflon insulation layer, which gives the graphene heating wire properties such as high temperature resistance, low friction, corrosion resistance, non-sticking and moisture resistance, and high insulation. After the cover 4 is installed on the locking frame 3, the heating element 5 can cover the bottom, two sides, and bottom surface of the locking rod 1 of the locking frame 3.

[0029] This embodiment also includes a copper sheet 6, such as Figure 5 As shown, a copper sheet 6 covers the heating element 5 at the bottom of the side cover 4b. Specifically, through holes 4d are provided on both the front and rear sides of the bottom surface of the side cover 4b. Several through holes 4d are arranged linearly along the length of the side cover 4b. A buckle 6a is provided on the copper sheet 6 corresponding to the position and shape of the through holes 4d. The buckle 6a is an L-shaped strip and passes through the through holes 4d to secure the copper sheet 6 to the bottom surface of the side cover 4b. Besides clamping the heating element 5, the copper sheet 6 also prevents direct friction between the heating element 5 and the locking rod 1, thus protecting the heating element 5. In other embodiments, the copper sheet 6 can be replaced with other heat-transferring and wear-resistant materials, including aluminum sheets, iron sheets, ceramics, and composite materials.
