[0006] The utility model provides a lightning arrester counter mounting device of high -speed railway traction substation round steel column, including the fixed hoop piece and the installation hoop piece of two unifications, the fixed hoop piece and the installation hoop piece's both sides symmetry have connected hole, and are fixed on the round steel column through bolt connection, the installation hoop piece outside positive center fixed connection installation bottom plate, the installation bottom plate has two angle steel mounting hole, and with the facade of angle steel is fixed through bolt, the plane of angle steel has the counter mounting hole of corresponding same specification with lightning arrester counter base, and is connected fixed with lightning arrester counter through bolt.

[0007] Further, the installation bottom plate is U-shaped, and two ends thereof are welded and fixedly connected with the installation hoop piece.

[0008] Further, the fixed hoop piece and the installation hoop piece are semicircular in shape, and the inner diameter thereof is 1-2mm larger than the outer diameter of the round steel column.

[0009] Further, the fixed hoop piece and the installation hoop piece are provided with rubber insulation gaskets on the inner side of the contact part with the round steel column, so as to protect the galvanized layer on the surface of the round steel column.

[0010] The lightning arrester counter mounting device of the high-speed railway traction substation round steel column has the following beneficial effects:

[0011] The lightning arrester counter mounting device of the high-speed railway traction substation round steel column is simple to install, easy to disassemble, and can protect the galvanized layer of the round steel column within the contact surface to a certain extent. Compared with the existing counter mounting structure, the device can better adapt to the construction conditions of different environments, and can avoid the damage of the finished product caused by transportation.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] Please refer to the following: Figures 1-5 A surge arrester counter installation device for a circular steel column in a high-speed railway traction substation includes a double-jointed fixing clamp 1 and a mounting clamp 4. The mounting clamp 4 has 14mm diameter connecting holes 7 on both sides. The outer center of the mounting clamp 4 is reliably connected to the mounting base plate 3 by welding. The mounting base plate 3 has two 11mm diameter angle steel mounting holes 9, which are connected to the vertical surfaces of angle steel 5 with 11mm diameter mounting holes in the same positions by two sets of bolts. The plane of angle steel 5 has a 14mm diameter counter mounting hole 8, which facilitates connection and fixation with a surge arrester counter 6.

[0020] Except for the mounting base plate 3, the fixed clamp plate 1 is the same as the mounting clamp plate 4. The mounting clamp plate 4 and the fixed clamp plate 1 are fixed to the circular steel column by two sets of bolts.

[0021] In this embodiment, the main bodies of the fixing clamp 1 and the mounting clamp 4 are semi-circular, with an inner diameter 1-2 mm larger than the outer diameter of the circular steel column. The mounting base plate 3 is U-shaped, and its two ends are welded and fixedly connected to the mounting clamp 4. Rubber insulating gaskets 2 are installed on the inner sides of both the fixing clamp 1 and the mounting clamp 4 to prevent damage to the galvanized layer on the surface of the circular steel column during installation and use.

[0022] In use, the fixing clamp 1 and the mounting clamp 4 are fixed to the circular steel column at a position 1.5m above the ground by passing a set of bolts through the connecting holes 7 on both sides. Then, the mounting base plate 3 and the angle steel 5 are tightly fixed with two sets of bolts through the angle steel mounting holes 9. Finally, the surge arrester counter 6 is tightly fixed with the angle steel 5 through the counter mounting holes 8. The overall installation of the structure is then completed.
