Description

Technical Field

[0001] The utility model relates to the technical field of wire clamps, in particular to a wire clamp for the power supply wire of a railway catenary. Background Technique

[0002] The railway catenary is the "aerial lifeline" to ensure the safe operation of high-speed railways. Its technological evolution always revolves around the three goals of "efficient power supply, reliable operation, and intelligent operation and maintenance". The railway catenary is the core infrastructure of electrified railways and undertakes the key task of providing stable electric energy for high-speed trains. The wire clamp fixes the wire / cable on the pole tower, wall, bracket or equipment, bears mechanical loads such as the self-weight, tension, and vibration of the conductor, and prevents the conductor from loosening, falling off or shaking.

[0003] An existing preformed wire clamp for the power supply wire of a railway catenary (publication number: CN221835255U) has at least the following drawbacks: This device is used to separate two power supply wires, but it is not convenient to install the power supply wire on the pole (or uniformly bundle and store multiple power supply wires). Moreover, the existing wire clamp is fixed by bolts, and the bolts are prone to looseness, resulting in the wire clamp falling off the wire and affecting the fixation. Content of the Utility Model

[0004] The purpose of the utility model is to solve the drawbacks existing in the prior art, and to propose a wire clamp for the power supply wire of a railway catenary.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A wire clamp for the power supply wire of a railway catenary includes an elastic clamp, an eyelet buckle and a push frame. An anti-slip pad is fixedly connected to the inner wall of the elastic clamp. Extension plates are integrally connected to both ends of the opening of the elastic clamp. The eyelet buckle is slidably connected through the extension plates. The push frame is slidably connected through the middle of the eyelet buckle. An arc-shaped plate is integrally connected to one end of the push frame close to the anti-slip pad. A silica gel pad is fixedly connected to the arc-shaped groove of the arc-shaped plate.

[0007] As a further scheme of the utility model, the push frame is located between several extension plates. Side grooves are opened on both sides of the push frame. A positioning block is fixedly connected to one side of the middle of the eyelet buckle. A spring is fixedly connected to one side of the arc-shaped plate close to the push frame.

[0008] As a further scheme of the utility model, the other end of the spring is fixedly connected to one side of the positioning block. The spring is located in the side groove. The side groove is slidably inserted on the positioning block.

[0009] As a further embodiment of this utility model, the eye-shaped buckle is provided with a first magnetic bolt and a second magnetic bolt on one side, the second magnetic bolt having the same structure as the first magnetic bolt, and the eye-shaped buckle is provided with a nut at the bottom.

[0010] As a further embodiment of this utility model, the screw of the first magnetic bolt passes through the buckle, the extension plate and the push frame, and is threaded into the nut. The extension plate and the push frame are positioned and connected to the buckle by the first magnetic bolt.

[0011] As a further embodiment of this utility model, a plurality of clamping pads are provided on one side of the eye-shaped buckle, and the plurality of clamping pads are respectively located on the top and bottom sides of the push frame, and the second magnetic bolt is threaded through and connected to the extension plate, the push frame and the clamping pads.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. Place the elastic clip on the outside of the wire on the pole, insert the I-shaped buckle through the extension plate, push the I-shaped buckle forward to approach the elastic clip ring, and then push the push bracket. The push bracket moves the arc plate and silicone pad forward, so that the silicone pad presses against one side of the wire to fix the wire in place. Use the first magnetic bolt to fix the I-shaped buckle, push bracket and extension plate in place to prevent the I-shaped buckle from moving and affecting the wire clamping. Anti-slip pads and silicone pads are installed on one side of the elastic clip and the arc plate to contact the wire. The anti-slip pads and silicone pads are made of silicone. The elasticity of the silicone can fill the small gaps between the wire clamp, the wire and the pole, preventing the wire clamp from sliding due to vibration and affecting the fixed connection of the wire.

[0014] 2. Magnets are embedded inside the first and second magnetic bolts to position them and prevent loosening due to vibration. The first magnetic bolt passes through the buckle, extension plate, and push frame, and is magnetically attracted to the threaded holes of the buckle, extension plate, and push frame by the magnet. A nut is then used to fix the first magnetic bolt in place. The second magnetic bolt passes through the extension plate and is fixedly connected by a nut. A gasket is installed in the gap between the extension plate and the push frame to prevent the extension plate from sinking due to lack of support, which could deform the threaded holes and affect the installation of the second magnetic bolt.

[0023] Reference Figures 1-4 A railway contact wire clamp includes an elastic clamp 1, a tic-tac-toe buckle 2, and a pusher 3. An anti-slip pad 102 is fixedly connected to the inner wall of the elastic clamp 1. Both ends of the opening of the elastic clamp 1 are integrally connected to an extension plate 101. The tic-tac-toe buckle 2 is slidably connected to the extension plate 101. The pusher 3 is slidably connected to the middle of the tic-tac-toe buckle 2. An arc-shaped plate 302 is integrally connected to one end of the pusher 3 near the anti-slip pad 102. A silicone pad 303 is fixedly connected in the arc groove of the arc plate 302.

[0024] In use, the elastic clip 1 is placed on the outside of the wire on the pole, the I-shaped buckle 2 is inserted through the extension plate 101, the I-shaped buckle 2 is pushed forward and moved closer to the elastic clip 1, and then the pusher 3 is pushed. The pusher 3 moves the arc plate 302 and the silicone pad 303 forward, so that the silicone pad 303 is pressed against one side of the wire to fix the wire. The first magnetic bolt 5 is used to fix the I-shaped buckle 2, the pusher 3 and the extension plate 101 to prevent the movement of the I-shaped buckle 2 from affecting the wire clamping. The elastic clip 1 and the arc plate 302 are both equipped with anti-slip pads 102 and silicone pads 303 on one side to contact the wire. The anti-slip pads 102 and silicone pads 303 are both made of silicone. The elasticity of the silicone can fill the small gaps between the wire clamp, the wire and the pole, and prevent the wire clamp from sliding due to vibration and affecting the fixed connection of the wire.

[0025] In this embodiment, the pusher 3 is located between several extension plates 101. Side grooves 301 are provided on both sides of the pusher 3. A positioning block 201 is fixedly connected to one side of the middle part of the eye-shaped buckle 2. A spring 4 is fixedly connected to the side of the arc plate 302 near the pusher 3.

[0026] When in use, push the pusher 3 to move. The pusher 3 is pushed by force to move the arc plate 302 in the middle of the eye-shaped buckle 2, so that the silicone pad 303 on one side of the arc plate is close to the inner side of the elastic clip 1. The sliding grooves on both sides of the pusher 3 slide outside the positioning block 201. The positioning block 201 positions the spring 4 to prevent the spring 4 from being displaced and deformed.

[0027] In this embodiment, the other end of the spring 4 is fixedly connected to one side of the positioning block 201. The spring 4 is located in the side groove 301, and the side groove 301 is slidably inserted into the positioning block 201.

[0028] When in use, the pusher 3 moves while the spring 4 is stretched. When it contacts the first magnetic bolt 5 and the second magnetic bolt 6 for positioning and connection, the spring 4 elastically retracts and drives the pusher 3 to reset and move away from the wire and column.

[0029] In this embodiment, the eye-shaped buckle 2 is provided with a first magnetic bolt 5 and a second magnetic bolt 6 on one side. The second magnetic bolt 6 has the same structure as the first magnetic bolt 5, and the bottom of the eye-shaped buckle 2 is provided with a nut 501.

[0030] In use, magnets are embedded inside the first magnetic bolt 5 and the second magnetic bolt 6 to position them and prevent the bolts from loosening due to vibration.

[0031] In this embodiment, the screw of the first magnetic bolt 5 passes through the buckle 2, the extension plate 101 and the push frame 3, and is threaded into the nut 501. The extension plate 101 and the push frame 3 are positioned and connected to the buckle 2 by the first magnetic bolt 5.

[0032] In use, the first magnetic bolt 5 passes through the buckle 2, the extension plate 101 and the pusher 3, and is magnetically attracted to the threaded holes of the buckle 2, the extension plate 101 and the pusher 3 by the magnet. Then, the nut 501 is used to fix the first magnetic bolt 5 in place.

[0033] In this embodiment, a plurality of clamping pads 7 are provided on one side of the eye-shaped buckle 2. The plurality of clamping pads 7 are located on the top and bottom sides of the push frame 3 respectively. The second magnetic bolt 6 is threadedly connected to the extension plate 101, the push frame 3 and the clamping pads 7.

[0034] In use, the second magnetic bolt 6 passes through the extension plate 101 and is fixedly connected by the nut 501. A clamping pad 7 is installed in the gap between the extension plate 101 and the pusher 3 to prevent the extension plate 101 from sinking due to lack of support, which would cause the threaded hole to deform and affect the installation of the second magnetic bolt 6.

[0035] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: The elastic clip 1 is fitted onto the outside of the wire on the pole; the I-shaped buckle 2 passes through the extension plate 101; the I-shaped buckle 2 is pushed forward to approach the elastic clip 1; then the pusher 3 is pushed, causing the arc plate 302 and the silicone pad 303 to move forward, so that the silicone pad 303 abuts against one side of the wire to fix the wire in place; the first magnetic bolt 5 is used to fix the I-shaped buckle 2, the pusher 3, and the extension plate 101 in place, preventing the movement of the I-shaped buckle 2 from affecting the wire clamping; the anti-slip pad 102 and the silicone pad 303 are in contact with the wire; both the anti-slip pad 102 and the silicone pad 303 are made of silicone material, and the elasticity of the silicone can fill the tiny gaps between the wire clamp, the wire, and the pole, preventing the wire clamp from sliding due to vibration and affecting the wire fixing connection; magnets are embedded inside the bolts of the first magnetic bolt 5 and the second magnetic bolt 6. The first magnetic bolt 5 and the second magnetic bolt 6 are positioned to prevent loosening due to vibration. The magnetic components of the first magnetic bolt 5 and the second magnetic bolt 6 will generate an axial attraction force on the connected parts, which is equivalent to superimposing a layer of magnetic preload on the mechanical preload of traditional bolts. The magnetic force is used to enhance the connection stability and suppress the loosening tendency caused by vibration or external force from multiple dimensions. The first magnetic bolt 5 passes through the buckle 2, the extension plate 101 and the pusher 3. It is magnetically attracted in the threaded hole of the buckle 2, the extension plate 101 and the pusher 3 by magnets. The first magnetic bolt 5 is then fixed in place by the nut 501. The second magnetic bolt 6 passes through the extension plate 101 and is fixedly connected by the nut 501. A clamping pad 7 is installed in the gap between the extension plate 101 and the pusher 3 to prevent the extension plate 101 from sinking due to lack of support, which would cause deformation of the threaded hole and affect the installation of the second magnetic bolt 6.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
