[0002] Railways are the economic artery of my country and are of great significance to the development of my country. In chain suspension, the contact wire is suspended on the load-bearing cable through the integral suspension string. After the contact suspension is erected, the contact wire, the load-bearing cable and the integral suspension string between the contact wire and the load-bearing cable have a certain tension. Therefore, when installing the suspension string clamp, it is very easy to cause the stop gasket to fail due to the overload of the bolt torque, which not only requires a lot of time and labor costs for rework of the installation, but also increases the risk of safety hazards, which is not conducive to driving safety. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings, the utility model provides an auxiliary device for the integral suspension string in the contact network suspension, which can apply torque to the bolt for tightening when installing the suspension string clamp, thereby preventing the bolt head from rotating excessively and expanding the stop gasket during tightening, thereby solving the failure of the stop gasket caused by torque overload and avoiding safety hazards.

[0006] Preferably, the stop gasket extends outwardly with at least one inner lug, the inner lug is bent toward the wire clamp body and can be matched and embedded in a limiting groove on the inner side wall of the accommodating cavity.

[0007] Preferably, the stop washer extends outwardly with at least one outer lug, and the outer lug is bent toward the bolt head side and is in close contact with the outer wall surface of the bolt head.

[0008] Preferably, the mold cavity has at least one surface that fits with the outer lug of the stop washer, so as to prevent the outer lug from expanding due to torque overload, thereby causing failure of the stop washer.

[0009] Preferably, the side wall of the accommodating cavity is provided with at least one limiting groove which fits with the inner lug of the stop gasket, so as to limit the deflection when the stop gasket is tightened.

[0010] Preferably, an arc cavity is also provided on the working end surface of the hand-held handle for avoiding the contact line.

[0011] Preferably, the handle is a D-shaped handle or an L-shaped handle.

[0012] Beneficial effect: The utility model provides an auxiliary device for the integral hanging string in the contact network suspension, which can not only prevent the bolt head from excessively rotating and expanding the brake gasket during tightening, solving the problem of stop gasket failure caused by torque overload, but also further improve the construction process level, avoid installation rework to a certain extent, improve installation efficiency, and provide a certain guarantee for driving safety.

[0022] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application are clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application. Example 1

[0023] like Figure 1-7 As shown, an auxiliary device for integral string suspension in overhead wire suspension includes a D-shaped handle 1 and a stop washer 2, wherein a receiving cavity 1-1 (such as Figure 5 As shown, the accommodating cavity is a U-shaped structure), which is used to accommodate the contact line suspension wire clamp 3. A cavity 1-2 is provided on the working end surface of the D-shaped hand-held handle 1, which is used to embed the bolt head 3-1 of the contact line suspension wire clamp 3. The cavity 1-2 has at least one surface that fits with the bolt head 3-1 of the contact line suspension wire clamp, which is used to stop the bolt; the stopping gasket 2 is installed in cooperation with the side of the bolt head 3-1 of the contact line suspension wire clamp 3, which is used to stop the bolt head 3-1. In this embodiment 1, the cavity 1-2 has two surfaces that fit with the bolt head 3-1 of the contact line suspension wire clamp 3.

[0024] like Figure 6-7 As shown, the stop washer 2 extends outwardly with at least one inner lug 2-1, which is bent toward the wire clamp body and can be matched and embedded in the limiting groove 1-3 on the inner side wall of the accommodating cavity 1-1. In this embodiment 1, one inner lug 2-1 is provided.

[0025] like Figure 6-7 As shown, the stop washer extends outwardly with at least one outer lug 2-2, which is bent toward the side of the bolt head 3-1 and is in close contact with the outer wall of the bolt head 3-1. In this embodiment 1, four outer lugs 2-2 are provided.

[0026] like Figure 2-4 As shown, the mold cavity 1-2 has at least one surface that fits with the outer lug 2-2 of the stop washer 2, so as to prevent the outer lug 2-2 from expanding due to torque overload and causing the stop washer 2 to fail.

[0027] like Figure 2-4 As shown, the side wall of the accommodating cavity 1-1 is provided with at least one limiting groove which fits with the inner lug 2-1 of the stop washer 2, and is used to limit the deflection of the stop washer 2 when it is tightened.
