When the device is used for an A-type gantry, a T-shaped supporting fixing body is formed between the longitudinal support rod 13 and the transverse support rod 14. Through the T-shaped fixing method, a pulling force opposite to the pulling force of the conductor is applied to the gantry crossbeam to achieve mechanical balance, prevent the gantry from tilting, and achieve a stabilizing function. The device can also be used for all T-type gantries in a substation, replacing the traditional repair welding method, and can quickly stabilize the A-type gantry and the T-type gantry. The first clamp 1 is detachably connected with a telescopic adjustment rod 15, and the telescopic adjustment rod 15 is used to adjust the position of the first clamp 1 The free end of the telescopic adjustment rod 15 is slidably connected with a support mechanism 19, and the support mechanism 19 is used to be fixed on the longitudinal support rod 13. By sliding the telescopic adjustment rod 15 on the support mechanism 19, the position of the first clamp 1 can be adjusted in the horizontal direction. By adjusting the length of the telescopic rod 18, the position of the first clamp 1 in the vertical direction can be adjusted, so that the connecting piece 11 can connect the first clamp 1 and the second clamp 2. The telescopic adjustment rod 15 includes a plug plate 16, an elastic rod 17 and a telescopic rod 18. The two ends of the elastic rod 17 are respectively connected to the plug plate 16 and the telescopic rod 18, and can be telescoped according to the distance between the plug plate 16 and the telescopic rod 18 to adapt to first clamps of different diameters. The plug plate 16 is plugged into the first clamp 1 to facilitate the connection or disassembly of the first clamp 1. The free end of the telescopic rod 18 is slidably connected to the support mechanism 19 to adjust the horizontal position of the first clamp 1.

[0028] Specifically, the first clamp 1 and the second clamp 2 each include two arms 3, both ends of the two arms 3 are provided with fixing ears 4, the corresponding fixing ears 4 are fixed by bolts 5, the two arms 3 can be fixed by the bolts 5, the diameters of the first clamp 1 and the second clamp 2 are realized by the bolts 5, and are suitable for being fixed on A-type gantries and T-type gantries of different sizes, the two ends of the connecting plate 11 are respectively connected to the fixing ears 4 of the first clamp 1 and the fixing ears 4 of the second clamp 2, the end of the connecting plate 11 is located between the fixing ears 4 of the two arms 3, and the two ends of the connecting plate 11 are provided with connecting holes 12, the bolts 5 pass through the connecting holes 12, which are convenient for connecting the first clamp 1 and the second clamp 2.

[0029] Specifically, a slot 6 is provided on the outer side of the arm 3, and the plug plate 16 is plugged into the slot 6. The plug plate 16 can be plugged into the arm 3 of the first clamp 1 through the slot 6. A locking piece 7 for the plug plate 16 is provided on the slot 6, which can lock the plug plate 16 to prevent the plug plate 16 from escaping from the slot 6, wherein the locking piece 7 includes a locking block 8 and an unlocking rod 9, and the locking block 8 is movably connected to the slot 6 through a locking spring 10. The unlocking rod 9 is slidably connected to the slot 6, and one end of the unlocking rod 9 passes through the locking spring 10 and is connected to the locking block 8. When the plug plate 16 is inserted into the slot 6, the locking block 8 is pressed downward. After the plug plate 16 slides over the locking block 8, under the action of the locking spring 10, the locking block 8 resets the locking plug plate 16. When unlocking, the unlocking rod 9 is pulled downward.

[0030] When in use, the second arm 3 is fixed to the transverse support rod 14, and one end of one of the connecting pieces 11 is connected between the two arms 3 of the second hoop 2, and the support mechanism 19 is fixed to the longitudinal support rod 13. The two arms 3 of the first hoop 1 are respectively located on both sides of the longitudinal support rod 13, and the first hoop 1 is located above the support mechanism 19. The plug plate 16 is plugged into the slot 6, and the locking piece 7 locks the plug plate 16, so that the telescopic adjustment rod 15 supports the arm 3, and the virtual hugging is adjusted according to the position to which the other end of the connecting piece 11 needs to be extended. The position of the bolt 5 used to connect the two fixing ears 4 of the first clamp 1 on the longitudinal support rod 13 allows the bolt 5 to simultaneously pass through the connecting hole 12 at the other end of the connecting piece 11 when fixing the two arms 3 of the first clamp 1, and the first clamp 1 is clamped tightly to the longitudinal support rod 13, so that the first clamp 1 and the second clamp 2 are connected through the connecting piece 11, and the A-type gantry and the T-type gantry are stabilized. After the stabilization is completed, the unlocking rod 9 can be pulled downward, the plug plate 16 is disengaged from the slot 6, and the supporting mechanism 19 can be removed from the longitudinal support rod 13, which can be used multiple times.

[0031] Example 2

[0032] See also Figures 1 to 7The difference between this embodiment and embodiment 1 is that: the support mechanism 19 includes a support hoop 20 and a support seat 21, the support seat 21 is connected to the outer side of the support hoop 20, the support hoop 20 can fix the support seat 21 on the longitudinal support rod 13, and a slide rail 22 is provided on the support seat 21, which is convenient for the telescopic rod 18 to slide along the slide rail 22.

The slider 26 is slidably connected to the slide rail 22, and the telescopic rod 18 can be driven to slide along the slide rail 22 by the slider 26. The positioning plate 24 is slidably connected to the slider 26 by a positioning spring 27. The locking rod 25 is threadedly connected to the slider 26 to push the positioning plate 24 downward to abut against the support seat 21. Both sides of the positioning plate 24 are respectively provided with convex strips 28 extending to the outside of the slider 26. The convex strips 28 are movably abutted against the support seat 21. The bottom of the convex strips 28 are provided with anti-slip grooves 29.
