[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Reference Figures 1-3 This utility model provides an embodiment of an auxiliary winding device for contact network ground wire, comprising a main body 1 and a main body 2 as the basic structure of the entire winding device. An auxiliary mechanism is provided on the outer side of the main body 1 and the main body 2. The auxiliary mechanism includes a mounting component 3, which includes mounting holes 31 opened on opposite sides of the main body 1 and the main body 2. The mounting holes 31 are located on the left side near the center point of the main body 1 and the main body 2, and are used to accommodate the ground wire rod, allowing the main body 1 and the main body 2 to be mounted on the outer side of the ground wire rod as a carrier for winding the contact network ground wire. This improves the regularity of the winding and reduces the space occupied. A nut 32 is provided on the inner wall of the main body 1, and a bolt 33 is provided through the inner wall of the main body 2. The bolt 33 and the nut 32 are threaded together, and the bolt 33 and the nut 32 work together to quickly splice and fix the main body 1 and the main body 2. Mounting grooves 35 are provided on the left inner walls of both the main body 1 and the main body 2 to accommodate locking blocks 36, thereby fixing the locking blocks 36 and thus fixing the fixing hooks 37.
[0030] Reference Figures 1-3 A fixing hook 37 is inserted into the inner wall of the main body 1 and the main body 2. The rear side of the fixing hook 37 is set as a ring. A slot 38 is opened on the left side of the fixing hook 37. A locking block 36 is engaged in the inner wall of the slot 38. The locking block 36 is set as a C shape. The slot 38 on the fixing hook 37 cooperates with the locking block 36 to firmly fix the fixing hook 37 to the main body 1 and the main body 2, preventing it from loosening or falling off during use. The locking block 36 is engaged in the inner wall of the mounting groove 35. A set screw 34 is threaded to the inner wall of the front side of the main body 1. Tightening the set screw 34 can fix the connected main body 1 and the main body 2 to the outside of the ground wire pole, ensuring that the winding device is structurally stable when working.
[0031] Reference Figures 1-3The auxiliary mechanism also includes an auxiliary component 4, which includes an elastic band 41 with one end inserted into the inner wall of the main body 1. The elastic band 41 is elastic; after the ground wire is wound around the main body 1 and the main body 2, pulling the elastic band 41 can bind the ground wire. Its elasticity provides appropriate constraint to prevent the wound ground wire from loosening, ensuring a tight and neat winding effect. The other end of the elastic band 41 is rotatably connected to a buckle 42, which is U-shaped. Connecting blocks 43 are fixedly connected to the right sides of both the main body 1 and the main body 2. The buckle 42 engages with the outside of the connecting blocks 43. The buckle 42 cooperates with the connecting blocks 43. After the ground wire is bound by the elastic band 41, the buckle 42... 2 is snapped onto the connecting block 43 to lock the elastic band 41, thereby stably fixing the ground wire and preventing it from shifting during use. The connecting block 43 is designed with a downward L-shape to lock the buckle 42. The upper right side of the main body 1 and the main body 2 is designed with an upward sloping protrusion, which can guide the winding direction of the ground wire during the winding process, prevent the ground wire from slipping, improve the winding regularity, and reduce the space occupied by the ground wire. A round rod is fixedly connected to the connection between the elastic band 41 and the main body 1, so that the elastic band 41 is not easy to fall off the main body 1 during stretching and use, and at the same time, it is convenient to maintain and replace the elastic band 41.
[0032] Working principle: In use, main body 1 and main body 2 are fitted onto the grounding pole through the mounting hole 31. The fixing hook 37 is inserted into the inner wall of main body 1 and main body 2. The C-shaped locking block 36 is inserted into the slot 38 on the left side of the fixing hook 37 and the mounting groove 35 on the left side of the inner wall of main body 1 and main body 2 to secure the fixing hook 37 and prevent it from loosening or falling off. Then, the bolt 33 is used to connect with the nut 32 on the inner wall of main body 1 to quickly splice and fix main body 1 and main body 2, initially forming the overall structure of the winding device.
[0033] At this point, tighten the set screw 34 on the inner front wall of the main body 1 to make it in close contact with the ground wire rod, and further fix the main body 1 and the main body 2 connected together firmly on the outside of the ground wire rod to ensure that the winding device is structurally stable during subsequent work. Generally, two such winding device assemblies are symmetrically installed on the upper and lower sides of the same ground wire rod.
[0034] Begin winding the contact wire, wrapping it around the main body 1 and the main body 2. During the winding process, the upward-sloping protrusions on the upper right side of the main body 1 and the main body 2 guide the winding direction of the ground wire and prevent it from slipping. After winding, pull the elastic band 41, which is inserted into the inner wall of the main body 1, and use the elasticity of the elastic band 41 to bind the wound ground wire, providing appropriate restraint to ensure that the wound ground wire is tight and neat and prevents it from loosening.
[0035] The other end of the elastic band 41 is rotated and connected to the U-shaped buckle 42, which is then snapped onto the downward L-shaped connecting block 43 that is fixedly connected to the right side of the main body 1 and the main body 2, thereby locking the elastic band 41 and thus stably fixing the ground wire to prevent it from shifting during use.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
