Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable fixing technology, specifically to jumper suspension clamps. Background Technology
[0002] Jumper suspension clamps are used in jumper suspension insulator strings in angle towers of 220kV and below transmission lines. They are mainly used to hold the jumper wires in the line and suspend them on the tower. They are also used to control the wind deflection and swaying of the conductors by connecting counterweight plates, ensuring a safe insulation gap between the jumper wires and the towers, and preventing fatigue breakage of the jumper wires due to swaying.
[0003] In existing technologies, some jumper suspension clamps rely solely on a simple clamping structure when holding cables, lacking a dedicated anti-slip structure. This leads to the cables easily loosening under the influence of external environmental factors (such as wind and vibration) during long-term use. Loose cables not only cause unstable power transmission, but frequent shaking can also cause wear on the cable sheath, leading to short circuits and other safety accidents, seriously threatening the safe operation of the power system.
[0004] In light of this, we have introduced jumper suspension clamps. Utility Model Content
[0005] The purpose of this invention is to provide a jumper suspension clamp to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a jumper suspension clamp, comprising: a U-shaped frame, a bolt A, and an upper clamp;
[0007] The bottom of the U-shaped frame is provided with a lower wire clamp, and the U-shaped frame and the lower wire clamp are fixedly connected. The bottom of the lower wire clamp is provided with a hanging plate, and the hanging plate and the lower wire clamp are fixedly connected.
[0008] Bolt A is located at the bottom of the lower clamp, and the top of bolt A penetrates the lower clamp.
[0009] The upper clamp is set on the top of the bolt A, and the upper clamp and the bolt A are connected by a thread. The nut A is set inside the upper clamp on the surface of the bolt A. The operator can adjust the tightness of the nut A and the bolt A through the slot to accommodate cables of different sizes.
[0010] The inner sides of the upper and lower clamps are provided with anti-slip structures, and the anti-slip protrusions of the anti-slip structures contact the cable to increase friction.
[0011] Preferably, the anti-slip structure includes a heat-resistant layer connected to one side of the anti-slip protrusion. The heat-resistant layer can resist the heat generated by the cable during the power-on process, and prevent the performance of the clamp material from deteriorating due to high temperature. A heat insulation layer is connected to one side of the heat-resistant layer. The heat insulation layer further prevents heat transfer and protects the bottom layer and the entire clamp structure. The bottom layer is connected to one side of the heat insulation layer. The bottom layer provides basic support for the anti-slip structure, ensuring the stability and reliability of the entire anti-slip structure. The anti-slip structure is connected to the inner sides of the upper clamp and the lower clamp respectively.
[0012] Preferably, the upper clamp has an internal slot for installing nut A, and the slot and the upper clamp are integrally formed.
[0013] Preferably, a bolt B is connected to one side of the U-shaped frame, and a nut B is connected to the bolt B after it passes through the U-shaped frame. The nut B is on the surface of the bolt B, which facilitates fixing it to an external object.
[0014] Preferably, one end of the bolt B has a through hole, and the through hole and the bolt B are integrally formed. A closed pin is connected inside the through hole, and the closed pin can further fix the nut B.
[0015] Preferably, the surface of the mounting plate has a through hole, and the through hole and the mounting plate are integrally formed.
[0016] Preferably, an anti-slip pad is attached to the surface of the bolt A below the lower clamp. The anti-slip pad further enhances the friction between the lower clamp and the cable, preventing the cable from slipping out of the lower clamp.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] (1) By using the upper and lower clamps in conjunction with bolt A and nut A, the cable can be tightly clamped to ensure that the cable will not easily loosen during use. The anti-slip protrusions in the anti-slip structure are in close contact with the cable, increasing friction and effectively preventing the cable from sliding. This ensures the stability of the cable during power transmission and reduces safety hazards caused by cable loosening.
[0019] (2) Through the heat-resistant layer and heat insulation layer in the anti-slip structure, the heat generated by the cable is effectively dealt with. The heat-resistant layer can prevent high temperature from damaging the clamp material and extend the service life of the clamp. The heat insulation layer further prevents heat transfer, protects the bottom layer and the entire clamp structure, improves the working reliability of the suspension clamp in high temperature environment, and ensures its stable operation.
[0020] (3) The suspension clamp is fixed by U-shaped bracket, bolt B and nut B, and closed pin is used to prevent nut B from loosening. This multiple fixing method greatly enhances the stability of the entire suspension clamp installation. The through hole on the hanging plate facilitates connection with other equipment, so that the suspension clamp can be better integrated into the entire cable fixing system, ensuring that the jumper can be suspended stably in complex environments.

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.
[0026] Please see Figure 1-3 This utility model provides a technical solution: a jumper suspension clamp, including: a U-shaped frame 1, a lower clamp 7 at the bottom of the U-shaped frame 1, and a hanging plate 14 at the bottom of the lower clamp 7;
[0027] Bolt A10, wherein bolt A10 is disposed at the bottom of lower clamp 7, and the top of bolt A10 penetrates lower clamp 7;
[0028] The upper clamp 6 is set on the top of the bolt A10, and the upper clamp 6 and the bolt A10 are connected by threads. The nut A11 is set inside the upper clamp 6 on the surface of the bolt A10. The operator can adjust the tightness of the nut A11 and the bolt A10 through the slot 9 to accommodate cables of different sizes.
[0029] The inner sides of the upper clamp 6 and the lower clamp 7 are provided with anti-slip structures 8, and the anti-slip protrusions 84 of the anti-slip structures 8 contact the cable to increase friction.
[0030] The anti-slip structure 8 includes a heat-resistant layer 83 connected to one side of the anti-slip protrusion 84. The heat-resistant layer 83 can resist the heat generated by the cable during the power-on process, and avoid the performance degradation of the clamp material due to high temperature. A heat insulation layer 82 is connected to one side of the heat-resistant layer 83. The heat insulation layer 82 further prevents heat transfer and protects the bottom layer 81 and the entire clamp structure. The bottom layer 81 is connected to one side of the heat insulation layer 82. The bottom layer 81 provides basic support for the anti-slip structure 8 and ensures the stability and reliability of the entire anti-slip structure 8. The anti-slip structure 8 is connected to the inner sides of the upper clamp 6 and the lower clamp 7 respectively.
[0031] The upper clamp 6 has an internal slot 9 for installing the nut A11, and the slot 9 and the upper clamp 6 are integrally formed.
[0032] One side of the U-shaped frame 1 is connected to a bolt B2, and the bolt B2 passes through the U-shaped frame 1 and is connected to a nut B3. The nut B3 is on the surface of the bolt B2, which makes it easy to fix to an external object.
[0033] One end of the bolt B2 has a through hole 5, and the through hole 5 and the bolt B2 are integrally formed. A closed pin 4 is connected inside the through hole 5, and the closed pin 4 can further fix the nut B3.
[0034] The surface of the mounting plate 14 is provided with a through hole 13, and the through hole 13 and the mounting plate 14 are integrally formed.
[0035] The surface of the bolt A10 is connected to an anti-slip pad 12 below the lower clamp 7. The anti-slip pad 12 further enhances the friction between the lower clamp 7 and the cable, preventing the cable from slipping out of the lower clamp 7.
[0036] Specifically, in use, firstly, use the bolt B2 and nut B3 on one side of the U-shaped frame 1 to fix the U-shaped frame 1 in the required position. After the bolt B2 passes through the U-shaped frame 1, tighten the nut B3 to make the U-shaped frame 1 firmly installed on the corresponding support structure. At the same time, a through hole 5 is opened at one end of the bolt B2. Insert the closed pin 4 into the through hole 5 to prevent the nut B3 from loosening and falling off during use, further enhancing the stability of the fixation.
[0037] The cable to be secured is placed between the upper clamp 6 and the lower clamp 7. Bolt A10 is set at the bottom of the lower clamp 7 and passes through the top of the lower clamp 7. The upper clamp 6 is installed on the top of the bolt A10. By rotating the nut A11 inside the upper clamp 6, it moves on the bolt A10, thereby adjusting the distance between the upper clamp 6 and the lower clamp 7 to achieve tight clamping of the cable. The slot 9 inside the upper clamp 6 provides space for the nut A11 to be installed and moved, which is convenient for operation.
[0038] The anti-slip structure 8 on the inner side of the upper clamp 6 and the lower clamp 7 plays an important role. The anti-slip protrusion 84 of the anti-slip structure 8 is in direct contact with the cable, which greatly increases the friction between the clamp and the cable and effectively prevents the cable from sliding in the clamp. In addition, a heat-resistant layer 83 is connected to one side of the anti-slip protrusion 84. The heat-resistant layer 83 can resist the heat generated by the cable during the power-on process and avoid the degradation of the clamp material performance due to high temperature. The heat insulation layer 82 on the side of the heat-resistant layer 83 further prevents heat transfer and protects the bottom layer 81 and the entire clamp structure. The bottom layer 81 provides basic support for the anti-slip structure 8 and ensures the stability and reliability of the entire anti-slip structure 8.
[0039] An anti-slip pad 12 is attached to the surface of bolt A10 located below the lower clamp 7, which further enhances the friction between the lower clamp 7 and the cable, preventing the cable from slipping out of the lower clamp 7. The hanging plate 14 is set at the bottom of the lower clamp 7, and the through hole 13 on its surface can be used to connect other components or devices, such as connecting with other suspension devices through the through hole 13, so as to realize the suspension and fixation of the jumper and complete the construction of the entire cable fixing system.
