Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically to a power connection clamp for overhead lines. Background Technology

[0002] On tension towers of power lines, jumper wires are generally used for connection. In order to facilitate various operations on the line, it is often necessary to disconnect and connect the jumper wires on appropriate tension towers to disconnect and connect the line. There are generally two types of jumper wire connections: one is that the jumper wires are connected to the tension clamps on both sides, and the other is that the jumper wires are connected in the middle using a professional clamp. The second method is mostly adopted according to operational needs.

[0003] In existing technologies, when connecting lines together using splice clamps, the splice clamps typically consist of two symmetrically arranged line clamps, which are then connected by multiple bolts. However, existing overhead power splice clamps make it difficult to quickly limit and fix the two line clamps during assembly, resulting in greater difficulty in tightening bolts at high altitudes and affecting installation efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a power connection clamp for overhead lines to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a power splicing clamp for overhead lines, comprising: a first clamping plate and a second clamping plate, wherein a first wire groove and a second wire groove are respectively provided at one end of the first clamping plate and the second clamping plate that are close to each other, and a protective pad is installed inside the first wire groove and the second wire groove, and a plug-in plate is installed at the edge of the first clamping plate near the second clamping plate, and a plug-in groove is provided on the surface of the second clamping plate near the plug-in plate;

[0006] The surface of the plug plate is provided with a limiting groove. A limiting block is slidably installed on the inner wall of the plug plate near the limiting groove. One end of the limiting block is connected to a connecting rod. A limiting spring is sleeved on the outside of the connecting rod. One end of the connecting rod extends through the outside of the second clamping plate and is connected to a handle.

[0007] A threaded post is installed at the middle of one end of the first clamping plate near the second clamping plate. A connecting hole is opened on the surface of the second clamping plate near the threaded post. One end of the threaded post slides through the connecting hole and is threaded with a fixing nut.

[0008] Preferably, there are two of each of the first and second wire grooves symmetrically arranged. The inner walls of the two first wire grooves and the two second wire grooves are fixedly installed with protective pads. Each protective pad has a number of protrusions evenly installed on its surface. The longitudinal section of each protrusion is an inclined surface, and the protrusions located inside the first and second wire grooves have opposite inclination angles.

[0009] Preferably, two plug-in plates are symmetrically arranged and fixedly installed on the first clamping plate, and one end of each plug-in plate is slidably inserted into an adjacent plug-in slot.

[0010] Preferably, two limiting grooves are formed on the surfaces of the two plug-in plates at their opposite ends, the inner wall of each limiting groove is slidably connected to one end of the adjacent limiting block, and the longitudinal section of each limiting block is trapezoidal.

[0011] Preferably, each of the two insertion slots has two storage slots on the inner wall near the limiting block. One end of each limiting block is fixedly connected to one end of an adjacent limiting spring. One end of each limiting spring is fixedly installed on the inner wall of the storage slot away from the insertion slot. One end of each limiting block is slidably connected to the inner wall of the adjacent storage slot.

[0012] Preferably, there are two symmetrically arranged handles, both of which are U-shaped. One end of each handle is fixedly connected to one end of an adjacent connecting rod, and the end of each connecting rod away from the handle is fixedly installed on an adjacent limiting block.

[0013] Preferably, two threaded posts are symmetrically arranged and fixedly installed on the first clamping plate. Two embedding grooves are opened on the surface of the second clamping plate away from the threaded posts. One end of each embedding groove is connected to an adjacent connecting hole. Both fixing nuts are located inside the adjacent embedding grooves.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention utilizes protective pads inside the first and second wire grooves to prevent the wires from sliding within them. By sliding the plug-in plate into the plug-in groove, the first and second wire clamping plates can be limited. The limiting groove on the surface of the plug-in plate facilitates the insertion of a limiting block into the limiting groove to limit the plug-in plate. The elasticity of the limiting spring prevents the limiting block from easily dislodging from the limiting groove, thus achieving the function of initially fixing the first and second wire clamping plates. This allows the fixing nut to be rotated to securely connect the first and second wire clamping plates, solving the problem of the difficulty of tightening bolts at high altitudes and thus avoiding affecting installation efficiency.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Please see Figures 1 to 6This utility model provides a technical solution: a power connection clamp for overhead lines, comprising: a first clamping plate 1 and a second clamping plate 2. The first clamping plate 1 and the second clamping plate 2 have a first groove 3 and a second groove 4 respectively at their adjacent ends. Protective pads 5 are installed inside both the first groove 3 and the second groove 4. A plug-in plate 11 is installed at the edge of the first clamping plate 1 near the second clamping plate 2, and a plug-in groove 12 is opened on the surface of the second clamping plate 2 near the plug-in plate 11. Two first grooves 3 and two grooves 4 are symmetrically arranged. Protective pads 5 are fixedly installed on the inner walls of both first grooves 3 and two second grooves 4. Several protrusions 6 are evenly installed on the surface of each protective pad 5. The longitudinal section of each protrusion 6 is an inclined surface, and the protrusions 6 located inside the first groove 3 and the second groove 4 have opposite inclination angles. Through the action of the protective pads 5 and the protrusions 6, the friction between the line and the first groove 3 and the second groove 4 can be increased, making the directions of limiting the two ends of the same line opposite, thereby improving the overall installation stability. Two plug-in plates 11 are symmetrically arranged and fixedly installed on the first wire clamping plate 1. One end of each plug-in plate 11 is slidably inserted into the adjacent plug-in slot 12, so as to facilitate the alignment of the end faces of the first wire clamping plate 1 and the second wire clamping plate 2.

[0025] A limiting groove 13 is formed on the surface of the plug-in plate 11. A limiting block 15 is slidably installed on the inner wall of the plug-in groove 12 near the limiting groove 13. A connecting rod 16 is connected to one end of the limiting block 15. A limiting spring 17 is sleeved on the outside of the connecting rod 16. One end of the connecting rod 16 extends through the outside of the second clamping plate 2 and is connected to a handle 14. Two limiting grooves 13 are formed on the surface of the two plug-in plates 11 at their far ends. The inner wall of each limiting groove 13 is slidably connected to one end of the adjacent limiting block 15. The longitudinal section of each limiting block 15 is trapezoidal, and the bottom corners of the two plug-in plates 11 are arc surfaces. When the plug-in plate 11 is inserted into the plug-in groove 12, it is easy to squeeze the limiting block 15 to make it enter the storage groove 18. Two insertion slots 12 each have two storage slots 18 on their inner walls near the limiting block 15. One end of each limiting block 15 is fixedly connected to one end of an adjacent limiting spring 17. One end of each limiting spring 17 is fixedly installed on the inner wall of the storage slot 18 away from the insertion slot 12, and one end of each limiting block 15 is slidably connected to the inner wall of the adjacent storage slot 18. When the limiting block 15 is inserted into the limiting slot 13, the limiting spring 17 is in its natural state. Two handles 14 are symmetrically arranged, both U-shaped. One end of each handle 14 is fixedly connected to one end of an adjacent connecting rod 16. The end of each connecting rod 16 away from the handle 14 is fixedly installed on the adjacent limiting block 15. When it is necessary to disassemble and separate the first clamping plate 1 and the second clamping plate 2, it is convenient to pull the handle 14 to make the limiting block 15 leave the limiting slot 13, and then it is convenient to rotate the fixing nut 8 to disengage it from the threaded post 7, thereby realizing the function of separating the first clamping plate 1 and the second clamping plate 2.

[0026] A threaded post 7 is installed at the center of one end of the first clamping plate 1 near the second clamping plate 2. A connecting hole 9 is formed on the surface of the second clamping plate 2 near the threaded post 7. One end of the threaded post 7 slides through the connecting hole 9 and is threadedly fitted with a fixing nut 8. Two threaded posts 7 are symmetrically arranged and fixedly installed on the first clamping plate 1. Two embedding grooves 10 are formed on the surface of the second clamping plate 2 away from the threaded post 7. One end of each embedding groove 10 is connected to the adjacent connecting hole 9. The two fixing nuts 8 are located inside the adjacent embedding grooves 10, which facilitates the storage and protection of the fixing nuts 8 and makes them less likely to be loosened by impact.

[0027] When this device is working, the protective pads 5 inside the first wire groove 3 and the second wire groove 4 prevent the wires from sliding inside the first wire groove 3 and the second wire groove 4. By sliding the plug plate 11 into the plug groove 12, the first clamping plate 1 and the second clamping plate 2 can be limited. The limiting groove 13 opened on the surface of the plug plate 11 makes it easy to insert the limiting block 15 into the limiting groove 13 and limit the plug plate 11. Through the elastic action of the limiting spring 17, the limiting block 15 is not easy to disengage from the limiting groove 13, thereby realizing the function of initially fixing the first clamping plate 1 and the second clamping plate 2, so that the fixing nut 8 can be rotated to fix the first clamping plate 1 and the second clamping plate 2 together. This solves the problem of the difficulty of tightening bolts at high altitudes, so as not to affect the installation efficiency.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
