Description

Technical Field

[0001] This utility model relates to the field of live-line working suspension technology, specifically a suspension device for a 10kV live-line working lead wire. Background Technology

[0002] In 10kV distribution network maintenance, repair, and user connection work, the application of live-line working technology has become the most direct and effective means to improve power supply reliability. When splicing branch lines or cable lines during 10kV live-line work, temporary guide lines need to be spliced ​​first to ensure the safety of the splicing. However, during the splicing of guide lines, the main body of the guide line is prone to bending and tilting, resulting in insufficient phase-to-phase and phase-to-ground distances. Furthermore, the current guide line suspension devices are basically designed with a single hook, which has poor stability and is prone to slipping off the conductor.

[0003] Patent application CN116914626A discloses a 10kV live-line working guide wire suspension device, including an insulating rod; the top of the insulating rod is provided with a wire hanger for suspending the device on the conductor; the bottom of the insulating rod is provided with a second operating rod connector for connecting an operating rod; the insulating rod is provided with a guide wire holder for fixing and clamping the guide wire and a guide wire clamp for pressing the guide wire away from the wire hanger; the guide wire holder and the guide wire clamp are located at the end of the insulating rod near the second operating rod connector, and the guide wire clamp is located between the guide wire holder and the second operating rod connector; the guide wire clamp and the guide wire holder are respectively connected to the insulating rod by a rotatable connection that can be limited.

[0004] However, the above-mentioned existing technology still has shortcomings in use: it sets two hooks at the top of the insulating rod, and the hooks are bent in opposite directions, which can solve the problem of easy slippage. However, after the hooks and wires are connected, the gap is large, which makes the hooks easy to slide along the wires. Therefore, there is a lack of suspension stability, and the suspension stability directly affects the stability of the drain line.

[0005] Therefore, this utility model provides a suspension device for a 10kV live-line working lead wire. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a suspension device for 10kV live working lead wires to solve the problems mentioned in the background technology. This utility model has the advantage of improving the stability of fixed-point suspension, making the temporary connection of the lead wire safer and more reliable.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a suspension device for a 10kV live-line working lead wire, comprising a suspension device body, an insulating rod provided on the suspension device body, two hooks with oppositely oriented hooks provided on the top of the insulating rod, a pressure rod located between the two hooks slidably connected to the top of the insulating rod, an insulating support plate fixedly connected to the top of the pressure rod, and a pressing mechanism for applying elastic thrust to the pressure rod provided on one side of the insulating rod.

[0008] Furthermore, at least two insulating skirts located between the two hooks are fixedly sleeved on the pressure rod.

[0009] Furthermore, a connecting rod is fixedly connected to the outer peripheral wall of the pressure rod at a position below the insulating umbrella skirt via a connecting block. This connecting rod is connected to the insulating rod via a clamping mechanism.

[0010] Furthermore, the clamping mechanism includes an arm plate and an elastic telescopic rod. One end of the arm plate is fixedly connected to the outer peripheral wall of the insulating rod, and its other end is hinged to one end of the elastic telescopic rod. The other end of the elastic telescopic rod is hinged to one side of the connecting rod.

[0011] Furthermore, an insulated handle is fixedly connected to the bottom of the connecting rod.

[0012] Furthermore, the top of the insulating rod is provided with a guide hole that slides with the pressure rod, and the opening of the guide hole is fitted with a sealing insulating sleeve.

[0013] Furthermore, a V-shaped groove is formed on the top of the insulating tray.

[0014] The beneficial effects of this utility model are as follows:

[0015] In this invention, by setting up a pressure rod, an insulating support plate, and a pressing mechanism, the pressing mechanism can push the insulating pressure plate to squeeze the guide inside the hook after the hook is attached to the wire. This increases the friction between the hook and the wire and improves the stability of the hook's fixed-point attachment.

[0016] In this utility model, the clamping mechanism includes an arm plate and an elastic telescopic rod. A connecting rod located on one side of the insulating rod is then set on the clamping rod. The arm plate and the insulating rod are fixedly connected, and one end of the arm plate is hinged to the connecting rod via the elastic telescopic rod. By swinging the elastic telescopic rod, the clamping rod can have a bidirectional elastic squeezing effect. This arrangement makes it more convenient to control the operation of clamping and releasing the insulating plate on the wire. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1 to 3 This utility model provides a technical solution: a suspension device for a 10kV live-line working lead wire, including a suspension device body 1, an insulating rod 11 is provided on the suspension device body 1, and two hooks 12 with opposite hooks are provided on the top of the insulating rod 11. Other structures on the suspension device body 1 can adopt the structures mentioned in the patent application document in the background art.

[0023] In this technical solution, a pressure rod 2 is slidably connected to the top of the insulating rod 11 between the two hooks 12. Preferably, the top of the insulating rod 11 has a guide hole 111 that slides with the pressure rod 2. A sealing insulating sleeve 1111 is fitted over the opening of the guide hole 111 to prevent conductive substances (such as water) from accidentally entering the guide hole 111. An insulating support plate 3 is fixedly connected to the top of the pressure rod 2. When the pressure rod 2 moves upward, it pushes the insulating support plate 3 upward. When the two hooks 12 are hooked onto the wire, the inner walls of the insulating support plate 3 and the two hooks 12 compress the wire, thereby improving the stability of the hooks 12 when hooked in place and effectively preventing the device from slipping during suspension.

[0024] In order to improve the insulation performance of the pressure rod 2, at least two insulating umbrella skirts 21 located between the two hooks 12 are fixedly sleeved on the pressure rod 2.

[0025] Furthermore, a pressing mechanism 4 is provided on one side of the insulating rod 11 to apply elastic thrust to the pressure rod 2. In a specific implementation, it is preferred that a connecting rod 22 is fixedly connected to the outer peripheral wall of the pressure rod 2 and located below the insulating umbrella skirt 21 via a connecting block 23. The connecting rod 22 is connected to the insulating rod 11 via the pressing mechanism 4. In use, the pressure rod 2 can be moved up and down by pulling the connecting rod 22. This arrangement can ensure the integrity of the insulating rod 11. A guide sleeve fitted on the outside of the insulating rod 11 can be fixedly connected to one side of the connecting rod 22.

[0026] Specifically, the clamping mechanism 4 includes an arm plate 41 and an elastic telescopic rod 42. One end of the arm plate 41 is fixedly connected to the outer peripheral wall of the insulating rod 11, and the other end is hinged to one end of the elastic telescopic rod 42. The other end of the elastic telescopic rod 42 is hinged to one side of the connecting rod 22. The elastic telescopic rod 42 adopts a two-section telescopic rod structure with built-in support springs. When the elastic telescopic rod 42 swings, its position is used to control the up and down movement of the connecting rod 22.

[0027] An insulating handle 221 is fixedly connected to the bottom of the connecting rod 22. The insulating handle 221 is the operator for manually pushing and pulling the connecting rod 22.

[0028] In this embodiment, the top of the insulating tray 3 is provided with a V-shaped groove 31. When the insulating tray 3 is used, the V-shaped groove 31 will lock onto the wire when the insulating tray 3 is pressed, which can effectively prevent the wire from coming off the insulating tray 3.

[0029] Working principle: When in use, after hanging the two hooks 12 on the wire, hold the insulating rod 11 and then manually grasp the insulating handle 221 and push it upward. At this time, the downward-tilting elongated elastic telescopic rod 42 will swing up and compress at the same time. When the elastic telescopic rod 42 starts to swing upward, it begins to extend and applies an elastic thrust to the connecting rod 22. When the pressure rod 2 moves upward, it will push the insulating support plate 3 to move upward. When the insulating support plate 3 squeezes the wire, the V-groove 31 will lock onto the wire. At this time, the device and the guide are in a fixed-point stable suspension connection state.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
