Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1

[0027] A preferred embodiment of the electrified railway catenary catenary adjustment device provided by this utility model is, for example... Figures 1 to 4 As shown: An adjustment device for the catenary cable of an electrified railway includes a first mounting plate 1, a second mounting plate 2 attached to the bottom of the first mounting plate 1, a screw 3 threadedly connected to the inside of the first mounting plate 1 and embedded in the second mounting plate 2, a top plate 4 fixedly connected to the top of the first mounting plate 1, a handwheel 5 rotatably connected to the bottom of the top plate 4, a screw 6 rotatably connected to one end of the handwheel 5, a slider 7 threadedly connected to the top plate 4, a rack 8 fixedly connected to the top of the slider 7, and a rack 8 on one side of the rack 8. A first gear 9 is meshed with the top plate 4 and rotatedly connected. A second gear 10 is meshed with the top plate 4 and rotatedly connected to one side of the first gear 9. A transmission arm 11 is fixedly connected to the top of the second gear 10. A first clamping ring 12 is fixedly connected to one end of the transmission arm 11. A connecting shaft 13 is rotatedly connected to one side of the first clamping ring 12. A second clamping ring 14 is fixedly connected to the surface of the connecting shaft 13. A connecting plate 15 is fixedly connected to the surface of the second clamping ring 14. An insertion hole 16 is provided inside the first clamping ring 12. A bolt 17 is threadedly connected inside the insertion hole 16.

[0028] In this embodiment, both the first mounting plate 1 and the second mounting plate 2 are semi-circular in shape. The first mounting plate 1 and the second mounting plate 2 are tightly fixed together by screws 3. The device can be fixed at the wrist arm position by the first mounting plate 1 and the second mounting plate 2.

[0029] In this embodiment, the top plate 4 is provided with a transverse groove whose size is adapted to the slider 7. The screw 6 drives the rack 8 to form a sliding structure through the slider 7. The screw 6 is controlled to rotate, and the screw 6 then drives the slider 7 to slide along the top plate 4. When sliding, the screw 8 is driven to move, and the rack 8 then drives the first gear 9 to move.

[0030] In this embodiment, the size of the first gear 9 is larger than that of the second gear 10. The second gear 10 drives the transmission arm 11 to form a rotating structure through the first gear 9. Since the diameter of the first gear 9 is larger than that of the second gear 10, the second gear 10 can be rotated more significantly by controlling the first gear 9 to rotate slightly, making it easier for the operator to operate.

[0031] In this embodiment, the transmission arm 11 is located at the center of the second gear 10. When the second gear 10 rotates, it will drive the transmission arm 11 to rotate. The load-bearing cables at the first clamping ring 12 and the second clamping ring 14 will be pulled by the rotation of the transmission arm 11 to achieve the purpose of adjustment.

[0032] In this embodiment, when the first clamping ring 12 and the second clamping ring 14 of the connecting plate 15 are tightly fitted, the positions of the two sets of insertion holes 16 correspond. When the second clamping ring 14 is closed, the bolt 17 is screwed from the connecting plate 15 into the insertion hole 16 to fix the first clamping ring 12 and the second clamping ring 14.

[0033] In this embodiment, the bolt 17 penetrates the connecting plate 15 and is embedded in the insertion hole 16. The first clamping ring 12 and the second clamping ring 14 form a fixed structure by the bolt 17. Fixing the first clamping ring 12 and the second clamping ring 14 can facilitate the improvement of the stability of the load-bearing cable.

[0034] Example 2

[0035] Based on Embodiment 1, a preferred embodiment of the electrified railway catenary catenary adjustment device provided by this utility model is as follows: Figures 1 to 4 As shown: protective rings 18 are fixedly connected at opposite corners of the first clamping ring 12 and the second clamping ring 14, and anti-slip rings 19 are fixedly connected inside the first mounting plate 1 and the second mounting plate 2.

[0036] In this embodiment, the protective ring 18 is arc-shaped and completely covers the diagonal part. By setting the protective ring 18, the protective ring 18 can cover the sharp parts of the first clamping ring 12 and the second clamping ring 14 to avoid scratching the load-bearing cable.

[0037] In this embodiment, the anti-slip ring 19 is made of rubber, and several sets of anti-slip rings 19 are equidistantly arranged. Under the action of the anti-slip ring 19, the stability effect can be improved after the device is installed.

[0038] The working principle and usage process of this utility model are as follows: First, when using the device, fix the device to the wrist arm position using the first mounting plate 1 and the second mounting plate 2. Open the second clamping ring 14 and install the load-bearing cable at the positions of the first clamping ring 12 and the second clamping ring 14. Then close the second clamping ring 14 and screw the bolt 17 from the connecting plate 15 into the insertion hole 16 to fix the first clamping ring 12 and the second clamping ring 14. Then, the operator can turn the handwheel 5 to control the screw 6 to rotate. The screw 6 then drives the slider 7 to slide along the top plate 4, and drives the rack 8 to move during sliding. The rack 8 then drives the first gear 9 to move. Since gear 9 has a larger diameter than the second gear 10, the second gear 10 can be rotated more significantly by slightly rotating the first gear 9, making it easier for the operator to operate. When the second gear 10 rotates, it will drive the transmission arm 11 to rotate. The load-bearing cables at the first clamping ring 12 and the second clamping ring 14 will be pulled by the rotation of the transmission arm 11 to achieve the purpose of adjustment. By setting the protective ring 18, the sharp parts of the first clamping ring 12 and the second clamping ring 14 can be wrapped to prevent the load-bearing cables from being scratched. In addition, the anti-slip ring 19 can improve the stability after the device is installed.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
