[0107] The present invention will be further described below with reference to embodiments. These embodiments are intended to illustrate the present invention and not to further limit the present invention.

[0108] A method for using a railway transport line device for crossing high-voltage transmission lines includes the following steps: constructing a bridge pier 1 on the high-voltage transmission line; after completing the construction of the bridge pier 1, installing a bridge 2 on the bridge pier 1; installing a track line 3 on the middle of the upper end face of the bridge 2; installing an inner support column 4 on the edge of the upper end face of the bridge 2; installing a pantograph 5 on the middle part of the inner support column 4; and using intermediate bolts and nuts, installing the inner end of the beam 61 on the upper end face of the inner support column 4. This completes the construction of the bridge pier 1, bridge 2, track line 3, inner support column 4, pantograph 5, and cable rack 6 on the high-voltage transmission line. A pile hole is formed at the bottom of the high-voltage transmission line located outside pile I13. Inner reinforcing bars 731, outer reinforcing bars 732, and intermediate reinforcing bars 733 are placed into the pile hole, exposing the conductive strip 734. Concrete mortar is poured into the pile hole. After the concrete mortar in the pile hole has solidified, pile II73 is formed. The templates for column II71 and platform II72 are installed on pile II73, exposing the conductive strip 734. [The text abruptly ends here, likely due to an incomplete sentence or missing information.] Concrete mortar is poured into the formwork. After the concrete mortar in the formwork of column 71 and abutment II 72 has set, column 71 and abutment II 72 are obtained. The formwork of column 71 and abutment II 72 is removed, and column 71 and abutment II 72 are cured. After the curing of column 71 and abutment II 72 is completed, the outer support column 7 is obtained. Along the transverse direction of the bridge 2, the end face of beam I 81 is connected to the upper side of the inner end face of column 71, so that beam II 82 passes through pier 1. Between 1 and 2, position beam II 82 at the lower end face of bridge 2, connect the end face of beam II 82 to the lower side of the inner end face of column 71 respectively, along the longitudinal direction of bridge 2, connect the end face of beam III 84 to the upper end of the inner side of column 71 respectively, connect the end face of beam IV 85 to the lower end of the inner side of column 71 respectively, place the inner end face of top plate 83 on the upper end face of beam I 81, inject connecting sealant between the groove of beam I 81 and top plate 83, so that the two sides are aligned. The sides of two adjacent top plate portions 83 are joined together. The upper side of the side plate portion 86 is placed on the lower end face of beam portion III 84, and the lower side of the side plate portion 86 is placed on the upper end face of beam portion IV 85. Connecting sealant is injected between the side plate portion 86 and beam portions III 84 and IV 85, so that the sides of two adjacent side plate portions 86 are joined together. Connecting sealant is injected between the connection parts of the top plate portion 83 and the side plate portion 86, thereby installing the cover assembly 8 on the outer support column 7. Place one end of the horizontal part of the frame 99 and one end of the vertical part of the frame 99 onto the outer end of the beam I 81. Connect the horizontal and vertical parts of the frame 99 to the beam I 81 using expansion bolts. Drill holes in the column 71 at the positions where the lower lightning rod frame 91 and the lightning rod grounding wire assembly 92 are installed to obtain mounting holes. Place the expansion bolts into the mounting holes and the through holes in the plate II 914. Install the lower lightning rod frame 91 onto the column 71 using the expansion bolts. Place the screw nut part 922 into the mounting holes and the through holes in the plate of the base 921. Install the lightning rod grounding wire assembly 92 onto the column 71 using the screw nut part 922. Install one lightning rod onto the plate I 98. Connect the other lightning rod to the beam I 81 using the intermediate bolt. The threaded hole of the cylindrical part 913 is connected to connect one end of the cable part 926 to the lightning rod on the upper lightning rod frame 9 and the lightning rod on the lower lightning rod frame 91 respectively. The cable clamp on the cable part 926 is connected to the threaded hole of the rod part II 911 and the threaded hole of the rod part III 912 through the intermediate bolt. The cable part 926 is placed in the lower hook of the hook part 924. The latch part 925 is installed between the U-shaped rod of the hook part 924 and the cable part 926. The cable part 926 is fixedly installed on the U-shaped rod of the hook part 924. The other end of the cable part 926 is welded to the conductive strip 734, thereby installing the upper lightning rod frame 9, the lower lightning rod frame 91 and the lightning rod grounding wire assembly 92 on the outer support column 7 and the housing assembly 8.

[0109] In verifying this invention, the inventors abandoned the existing technical features of using piers and box girders to support the track line under high-voltage transmission lines. Instead, they first proposed a technical feature where the railway transport line located on the high-voltage transmission line is situated within a tunnel isolated from the cable. This resulted in the first unexpected technical effect: placing an isolator on the high-voltage transmission line eliminates the impact of the high-voltage transmission line on the running train, improving the train's operational safety. The second unexpected technical effect was achieved: pier 1 supports bridge 2, and the distributed support of abutment I12 and pile I13 improves the stability of the support for bridge 2. The third unexpected technical effect was also achieved. Results: The cable frame 6 supports the mains power cable. The triangular structure between beam 61, insulator I 62, and insulator II 63 improves the stability of the support for the mains power cable. The angle α between the center lines of insulator I 62 and II 63 eliminates the risk of arcing between the mains power cable, pantograph 5, and high-voltage transmission line. A fourth unexpected technical effect is achieved: The outer support column 7 supports the casing assembly 8 and connects it to the lightning rod grounding wire assembly 92. The platform II 72 and pile II 73 improve the stability of the support for the casing assembly 8. The inner steel reinforcement 731, outer steel reinforcement 732, intermediate steel reinforcement 733, and conductive strips further enhance the stability. The body 734 improves the grounding performance of the lightning rod, resulting in the fifth unexpected technical effect: It enables the enclosure assembly 8 to connect the bridge 2, and the internal frame composed of beam I 81, beam II 82, beam III 84, and beam IV 85 improves the support strength of the enclosure connection. The mating of the top plate 83 and side plate 86 improves the overall sealing performance of the enclosure connection, resulting in the sixth unexpected technical effect: It enables the upper lightning rod frame 9 to fix the lightning rod, and the concave arc surface of plate I 98 improves the fixing strength of the lightning rod, resulting in the seventh unexpected technical effect: It enables the lower lightning rod frame 91 to fix the lightning rod, and the convex arc surface of cylinder 913 improves the fixing strength of the lightning rod. Furthermore, by increasing the outward swing distance of the lightning rod, an eighth unexpected technical effect was achieved: the lightning rod was grounded via the base 921, screw and nut 922, ring 923, hook 924, latch 925, and cable 926. The installation position of the cable 926 was adjusted through these components, optimizing the installation connection performance with the lightning rod, resulting in a ninth unexpected technical effect: tunnel installation between a moving railway train and a high-voltage transmission line was achieved, ensuring that the airflow generated by the moving train flows in a prescribed direction and no longer affects the high-voltage transmission line.The tenth unexpected technical effect was achieved: lightning arresters were used to provide lightning protection for railway trains in motion on vast high-voltage transmission lines, improving the operational safety of railway transport line equipment. The eleventh unexpected technical effect was achieved: insulated safety protection was implemented for railway trains in motion, improving the power supply safety of railway transport line equipment.
