Description

Technical Field

[0001] The present invention relates to the technical field of line installation, and more specifically, to a hardware fitting for a power line. Background Art

[0002] Iron or aluminum metal accessories widely used in power transmission lines are collectively referred to as hardware. Suspension wire clamps are composed of a bracket U-bolt, a wire clamp hull made of forgeable cast iron, and a pressure plate. They are mainly used to fix the wire on the insulator string or lightning conductor, support and disperse the force of the wire, and ensure the safe operation of the power line.

[0003] When the suspension clamp is used in a large-span transmission line in a terrain such as a valley, a deep ditch, a large river, a lake, and a strait, the suspension clamp is subjected to greater tension due to the large span of the conductor. In addition, the terrain such as a valley, a deep ditch, a large river, a lake, and a strait will increase the frequency of changes in wind speed and direction. Therefore, under the action of wind force, relative movement occurs between the hull and the hanging plate of the suspension clamp, and the hanging plate swings around the hull axis at a small angle, causing grooves to form on the hull axis during the swinging process. As time goes by, these grooves will gradually deepen. When the grooves reach a certain extent, the strength of the hull axis will be greatly reduced, eventually causing the hull to fall from the suspension clamp, causing an accident. Therefore, technicians need to conduct a comprehensive inspection of the suspension clamp regularly.

[0004] Existing suspension clamps are generally equipped with two mutually perpendicular shafts, so that the hull can swing in two horizontal directions. When the wire drives the hull to vibrate up and down, the connection parts are easily deformed due to the lack of space for the hull to move up and down, thus affecting the service life of the suspension clamp. In addition, there is a lack of lubrication between the shaft and the connection parts. Due to the large pressure between the shaft and the connection parts, the high pressure causes the contact parts between the shaft and the connection parts to wear more, so that the inspection frequency needs to be increased, which increases the workload of technicians. If the suspension clamp is already in a deep degree of wear before the designated inspection time is reached, it is dangerous.

[0005] For example, the patent with application number 202411413392.4 discloses a suspension wire clamp for power lines, including a wire clamp body, a pressure plate, a U-shaped bolt, a connecting bolt and a U-shaped hanging plate. Two outwardly protruding limiting grooves are symmetrically arranged on both sides of the lower end of the wire clamp body, and the limiting grooves match the outer bottom setting of the U-shaped bolt. Four outwardly protruding limiting channels are symmetrically arranged on the front and rear end surfaces of the wire clamp body above the limiting grooves, and the limiting channels match the screw setting of the U-shaped bolt. After the U-shaped bolt is inserted into the limiting grooves and limiting channels in sequence from bottom to top, an outer fastening nut, a buffer spring and an inner fastening nut distributed up and down are sequentially arranged on the end of the screw. The outer side of the U-shaped bolt on the same side of the pressure plate has an arc structure extending slightly outward and upward along its outer end surface. The surface of the wire clamp body, the pressure plate, the U-shaped bolt, the U-shaped hanging plate, the connecting bolt, the limiting groove and the limiting channel are coated with a wear-resistant layer; it has the advantages of good locking effect, good wear resistance and long service life.

[0006] Although the above patent improves the lubrication effect of the contact part between the shaft and the connecting parts and reduces the wear degree of the hull and the connecting parts, it cannot automatically detect the amount of lubricating oil between the shaft and the connecting parts. When there is more lubricating oil in the contact part between the shaft and the connecting parts, it is easy to cause waste of lubricating oil. When there is less lubricating oil in the contact part between the shaft and the connecting parts, the lubrication effect is not obvious, the anti-wear effect is limited, and the lubricating oil will be lost during use. The cavity for storing lubricating oil in the above patent adopts a built-in design. After the lubricating oil is used up, it cannot be added again. The only way is to replace the whole set of suspension wire clamps, which increases the cost of use.

[0007] Therefore, the present invention proposes a hardware for power lines to solve the above problems. Summary of the invention

[0024] Technical effects and advantages of the present invention:

[0025] 1. The present invention provides a connecting portion, in which a first rotating shaft and a second rotating shaft which are perpendicular to each other are built-in. This design enables the electric wire to swing freely in the horizontal direction when encountering horizontal wind force, thereby effectively weakening the impact of wind force on the suspension wire clamp. A movable space is specially designed on the lower side of the movable plate in the connecting portion, allowing the first rotating shaft to move up and down a certain distance in this space. Compared with the traditional suspension wire clamp, this improvement increases the freedom of movement in the up and down directions, significantly reduces the impact of wind force on components, avoids deformation of the movable plate when the electric wire vibrates up and down, and thus extends the service life of the movable plate.

[0026] 2. The present invention is provided with a control component and an oil injection component, which can accurately adjust the amount of lubricating oil according to the change of friction between the moving parts to avoid waste of lubricating oil. When the friction increases, the system can automatically spray lubricating oil into the moving parts to increase lubrication and reduce friction. When the friction decreases, the oil injection is automatically stopped. This automatic adjustment mechanism not only reduces the wear between components, but the torsion spring force in the control component can also effectively buffer the swing amplitude of the moving parts, further reducing the swing under the action of wind, thereby extending the service life of the suspension wire clamp, reducing the inspection frequency and workload of technicians, and effectively preventing safety hazards caused by deep wear.

[0027] 3. The present invention is also provided with a convenient oil storage part, in which the oil storage box is externally arranged and provided with a refueling port, so that the technicians can easily add lubricating oil during the maintenance process. The lower end of the oil storage part is equipped with a plurality of oil pipes, which can provide sufficient lubricating oil support for all lubrication parts at the same time. This design makes it possible to continuously lubricate the moving parts without replacing the entire set of suspension wire clamps after the lubricating oil is exhausted, thereby greatly reducing the cost of use.

[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] Embodiment 1

[0054] See also Figures 1 to 13 As shown, the hardware for power lines in the embodiment of the present invention includes a device body 1 and a connecting part 2.

[0055] See also Figure 1 , Figure 2 and Fig.12 As shown, the device body 1 includes a hull 101 with an opening facing upward, the hull 101 is used to lift the wire upward, two symmetrically distributed first through holes 102 are opened at the upper end of the hull 101, and two symmetrically distributed fixing components 103 are provided on the lower side of the hull 101, and the fixing components 103 are used to fix the wire on the hull 101; Figure 4 As shown, the connecting portion 2 includes a movable plate 201 arranged between two first through holes 102, a first rotating shaft 202 is inserted between the two first through holes 102, the first rotating shaft 202 passes through the lower side of the movable plate 201, and two symmetrically distributed second through holes 203 are opened at the upper end of the movable plate 201, and a second rotating shaft 204 perpendicular to the first rotating shaft 202 is inserted between the two second through holes 203.

[0056] It should be noted that the first rotating shaft 202 passes through the lower side of the movable plate 201, and the height of the space under the movable plate 201 is greater than the diameter of the first rotating shaft 202, so that the first rotating shaft 202 can move up and down a certain distance under the movable plate 201. When the electric wire vibrates up and down due to the wind, the electric wire drives the first rotating shaft 202 to move up and down under the movable plate 201. Compared with the existing suspension wire clamp, the freedom of movement in the up and down direction is increased, the deformation of the movable plate 201 is avoided, and the service life of the movable plate 201 is increased.

[0057] See also Figure 2 , Figure 3 , Figure 4 and Fig.13 As shown, the fixing assembly 103 includes a fixing rod 1031, a plurality of symmetrically distributed first clearance holes 1032 are opened on the side wall of the hull 101, two symmetrically distributed pressure plates 1033 are arranged in the hull 101, and second clearance holes 1034 corresponding to the first clearance holes 1032 are opened at the ends of the pressure plates 1033. The lower end of the fixing rod 1031 can be stuck under the hull 101, and the upper end of the fixing rod 1031 passes through the first clearance hole 1032 and the second clearance hole 1034 and is provided with a nut 1035.

[0058] See also Figure 1 , Figure 2 and Figure 4 As shown, two symmetrically distributed retaining rings 5 ​​are provided at the lower end of the hull 101 , and the lower end of the fixing rod 1031 can be clamped between the two symmetrically distributed retaining rings 5 ​​.

[0059] See also Figure 5 and Fig.13 As shown, two symmetrically distributed elastic pads 9 are provided at the inner bottom of the hull 101 , and the elastic pads 9 are located directly below the pressure plate 1033 .

[0060] See also Figure 1 As shown, the end of the hull 101 is in an outwardly slanted shape, leaving a swinging space for the wires at the end of the hull 101, thereby solving the problem that the end of the hull 101 is easily damaged due to excessive torque when in direct contact with the wires.

[0061] When in use, in the initial state, the pressing plate 1033 is located directly above the elastic pad 9 , the first clearance hole 1032 and the second clearance hole 1034 on the corresponding side are vertically opposite, and the nut 1035 is connected to the fixing rod 1031 .

[0062] Before installing the wires, it is necessary to first fix the device body 1 under the connecting component in the wire line. The technician first takes the device body 1 to the wire installation location, pulls out the second shaft 204 from the two second through holes 203, and then rotates multiple nuts 1035 counterclockwise in sequence to separate the nuts 1035 from the fixing rod 1031, thereby removing the fixing rod 1031 from the first make way hole 1032 and the second make way hole 1034, and then the pressure plate 1033 can be removed from the hull 101.

[0063] The technician places the lower end of the connecting component in the line on the upper side of the movable plate 201, aligns the two second through holes 203 on the movable plate 201 with the holes on the connecting component, and then inserts the second rotating shaft 204 into the hole and the two second through holes 203, so that the movable plate 201 and the connecting component in the wire line are in a state of rotational connection. At this time, the hull 101 is suspended under the connecting component.

[0064] The technician passes the wire through the inside of the hull 101, and the outer surface of the wire contacts the elastic pad 9 inside the hull 101. Then, the two pressing plates 1033 are covered on the top of the wire, so that the first clearance hole 1032 and the second clearance hole 1034 are opposite to each other, and the fixing rod 1031 is passed from bottom to top through the first clearance hole 1032 and the second clearance hole 1034. At this time, the upper end of the fixing rod 1031 is located above the pressing plate 1033, and the lower end of the fixing rod 1031 is stuck between two symmetrically distributed retaining rings 5. The two retaining rings 5 ​​can prevent the fixing rod 1031 from being stuck. The lower end of the fixed rod 1031 swings to increase the stability of the wire after it is fixed. Finally, the nut 1035 is threadedly connected to the upper end of the fixed rod 1031. The nut 1035 is rotated clockwise to make the nut 1035 contact with the upper end surface of the pressure plate 1033. Then the nut 1035 drives the pressure plate 1033 to move downward. The distance between the pressure plate 1033 and the elastic pad 9 gradually decreases until the pressure plate 1033 fixes the wire in the hull 101, thereby completing the fixation of the wire. The elastic pad 9 in the hull 101 can reduce the wear of the wire.

[0065] When the wires are affected by wind, they will drive the hull 101 to swing horizontally around the first shaft 202 and the second shaft 204. At the same time, the first shaft 202 can move up and down a certain distance in the movable plate 201, thereby reducing the impact of wind on the connecting part 2 and avoiding deformation of the movable plate 201.

[0066] Embodiment 2

[0067] It is found in actual use that when the electric wire is swung by the wind, the electric wire will drive the hull 101 and the movable plate 201 to swing around the first rotating shaft 202 and the second rotating shaft 204 respectively. Due to the lack of lubrication at the contact position, the relative rotation between the first rotating shaft 202 and the first through hole 102 will cause wear, and the relative rotation between the second rotating shaft 204 and the second through hole 203 will cause wear. In addition, due to the large pressure between the shaft body and the connecting part 2, the high pressure causes the contact position between the shaft body and the connecting part to wear more severely, so that the inspection frequency needs to be increased, which increases the workload of technicians. If the suspension clamp is already in a deep degree of wear before the specified inspection time, it is dangerous. Further improvements are made on the basis of the above embodiment.

[0068] See also Figure 4 , Figure 7 and Fig.10 As shown, the hardware for power lines also includes a lubrication part 3, which includes a plurality of swivels 301 and a shell 302. The shell 302 is fixed to the outside of the swivel 301 on the same side. The plurality of swivels 301 are respectively inserted into the first through hole 102 and the second through hole 203, and the plurality of swivels 301 are rotatably connected to the first rotating shaft 202 and the second rotating shaft 204, respectively. A control component 303 and an oil injection component 304 are provided in the shell 302. The outlet of the oil injection component 304 is aligned with the swivel 301. The control component 303 is used to control the operation of the oil injection component 304 according to the amount of lubricating oil on the swivel 301. Each shell 302 is provided with an oil inlet 305.

[0069] When the lubricating oil on the rotating ring 301 is sufficient, the control component 303 controls the oil injection component 304 to stop delivering the lubricating oil. When the lubricating oil on the rotating ring 301 is insufficient, the control component 303 controls the oil injection component 304 to deliver the lubricating oil from the outlet.

[0070] See also Figure 4 , Fig.10 and Fig.11 As shown, the control component 303 includes a torsion spring 3031 located in the shell 302, a first clamping plate 3032 is provided on the inner surface of the shell 302, and a second clamping plate 3033 located in the shell 302 is provided on the outer surface of the first rotating shaft 202 and the second rotating shaft 204. One end of the torsion spring 3031 is fixed to the first clamping plate 3032, and the other end is fixed to the second clamping plate 3033.

[0071] It should be noted that the torsion spring 3031 has a certain initial elastic force. When the torsion force between the first clamp 3032 and the second clamp 3033 is less than the initial elastic force of the torsion spring 3031, that is, the friction force between the swivel 301 and the first through hole 102 or the second through hole 203 is less than the initial elastic force of the spring, the torsion spring 3031 always maintains its initial length. When the torsion force between the first clamp 3032 and the second clamp 3033 is greater than the initial elastic force of the torsion spring 3031, that is, the friction force between the swivel 301 and the second through hole 203 or the second through hole 203 is greater than the initial elastic force of the torsion spring 3031, the torsion spring 3031 begins to twist.

[0072] See also Figures 5 to 10 As shown, the oil injection assembly 304 includes a cylinder body 3041 fixed to the shell 302, a piston 3042 is slidably connected in the cylinder body 3041, a pressure rod 3043 is provided on the piston 3042, the first rotating shaft 202 and the second rotating shaft 204 are provided with a connecting plate 3044 located in the shell 302, the free end of the pressure rod 3043 passes through the cylinder body 3041 and is fixed to the connecting plate 3044, and an inlet pipe 3045 and a liquid outlet pipe 3046 are provided on the end of the cylinder body 3041 away from the pressure rod 3043, the free end of the liquid inlet pipe 3045 is connected to the oil inlet port 305, and the free end of the liquid outlet pipe 3046 passes through the shell 302 and is aligned with the swivel 301.

[0073] See also Figure 5 , Figure 6 , Figure 8 and Fig. 9 As shown, a first one-way valve 6 with an opening toward the cylinder body 3041 is provided in the liquid inlet pipe 3045 , and a second one-way valve 7 with an opening away from the cylinder body 3041 is provided in the liquid outlet pipe 3046 .

[0074] It should be noted that the lubricating oil in the liquid inlet pipe 3045 can only flow toward the direction close to the cylinder body 3041, but cannot flow toward the direction away from the cylinder body 3041; the lubricating oil in the liquid outlet pipe 3046 can only flow toward the direction away from the cylinder body 3041, but cannot flow toward the direction close to the cylinder body 3041.

[0075] On the basis of the above embodiment, when in use, after the electric wire is fixed to the hull 101, when the wind drives the electric wire to swing, the electric wire drives the hull 101 to swing around the first rotating shaft 202, and drives the movable plate 201 to swing around the second rotating shaft 204 at the same time.

[0076] When the amount of lubricating oil between the swivel 301 and the first through hole 102 or the second through hole 203 is sufficient, the friction between the swivel 301 and the first through hole 102 or the second through hole 203 is small, and the initial elastic force of the torsion spring 3031 is greater than the friction, so the torsion spring 3031 does not twist. Since the first rotating shaft 202 and the second rotating shaft 204 do not swing, the second clamping plate 3033 arranged on the first rotating shaft 202 and the second rotating shaft 204 and fixed to one end of the torsion spring 3031 does not swing, and the first clamping plate 3032 fixed to the other end of the torsion spring 3031 does not swing either. The shell 302 fixed to the first clamping plate 3032 does not rotate, and the swivel 301 fixed to the shell 302 does not rotate either. Sufficient lubricating oil can reduce the wear between the swivel 301 and the first through hole 102 or the second through hole 203.

[0077] When the amount of lubricating oil between the swivel 301 and the first through hole 102 or the second through hole 203 is insufficient, the friction between the swivel 301 and the first through hole 102 or the second through hole 203 increases, and the initial elastic force of the torsion spring 3031 is less than the friction, the first through hole 102 on the hull 101 and the second through hole 203 on the movable plate 201 both drive the swivel 301 to rotate through the friction, the swivel 301 drives the housing 302 to rotate, and the housing 302 drives the first clamping plate 3032 to swing to overcome the elastic force of the torsion spring 3031 , and the second clamping plate 3033 is arranged on the first rotating shaft 202 and the second rotating shaft 204 and cannot swing, the torsional force of the torsion spring 3031 between the first clamping plate 3032 and the second clamping plate 3033 increases, and at the same time the shell 302 drives the cylinder body 3041 to swing, and since the pressure rod 3043 is fixed to the connecting plate 3044 on the first rotating shaft 202 or the second rotating shaft 204, a relative swing occurs between the pressure rod 3043 and the cylinder body 3041, and the piston 3042 fixed to the pressure rod 3043 begins to slide in the cylinder body 3041.

[0078] When the pressure rod 3043 moves in the direction of extending out of the cylinder body 3041, negative pressure is formed in the space between the piston 3042 and the bottom of the cylinder body 3041, and a first one-way valve 6 with an opening toward the cylinder body 3041 is provided in the liquid inlet pipe 3045, and a second one-way valve 7 with an opening away from the cylinder body 3041 is provided in the liquid outlet pipe 3046. The negative pressure in the cylinder body 3041 can only be transmitted to the liquid inlet pipe 3045, thereby attracting the lubricating fluid into the cylinder body 3041.

[0079] When the pressure rod 3043 moves toward the direction of entering the cylinder body 3041 with the reciprocating swing of the hull 101, the pressure rod 3043 drives the piston 3042 to slide toward the bottom of the cylinder body 3041, and the lubricating oil in the cylinder body 3041 is squeezed and can only enter the liquid outlet pipe 3046, and pass through the second one-way valve 7 in the liquid outlet pipe 3046, and finally spray out from the free end of the liquid outlet pipe 3046, and the free end of the liquid outlet pipe 3046 is aligned with the swivel 301, and the lubricating oil is sprayed between the swivel 301 and the first through hole 102 or the second through hole 203, thereby reducing the friction between the swivel 301 and the first through hole 102 or the second through hole 203, so that the friction becomes smaller than the initial elastic force of the torsion spring 3031 again, and the piston 3042 stops sliding, and the lubricating oil stops spraying out.

[0080] Technicians can also control the trigger threshold of lubricating oil spraying by setting the initial elastic force of the torsion spring 3031, thereby automatically adjusting the amount of lubricating oil between the swivel 301 and the first through hole 102 or the second through hole 203, reducing wear between moving parts and increasing the service life of the suspension wire clamp.

[0081] Embodiment 3

[0082] In actual use, it was found that the lubricating oil would be lost during use, and the amount of lubricating oil in the cavity for storing the lubricating oil was limited. After the lubricating oil was used up, it could not be added further, and the whole set of suspension wire clamps had to be replaced, which increased the cost of use. Further improvements were made on the basis of the above embodiments.

[0083] See also Figure 4 , Figure 5 and Figure 7 As shown, the hardware for power lines also includes an oil storage part 4, which includes an oil storage box 401 located on the upper side of the movable plate 201, and a plurality of oil pipes 402 corresponding to the oil inlets 305 are provided on the lower side of the oil storage box 401, and the free ends of the oil pipes 402 are connected to the oil inlets 305 on the same side.

[0084] See also Figure 1 and Figure 5 As shown, a baffle plate 8 is provided in the middle of the movable plate 201 , a distance is provided between the baffle plate 8 and the first rotating shaft 202 , and the oil storage box 401 is located above the baffle plate 8 .

[0085] See also Figure 4 and Figure 5 As shown, a refueling port is provided at the upper end of the oil storage box 401, and a sealing plug 10 is detachably connected to the refueling port.

[0086] On the basis of the above embodiments, during use, when the amount of lubricating oil between the swivel 301 and the first through hole 102 or the second through hole 203 is insufficient, a negative pressure is formed in the cylinder 3041 as the piston 3042 slides away from the bottom of the cylinder 3041. The negative pressure is transmitted to the oil inlet 305 through the liquid inlet pipe 3045, and then transmitted to the oil storage box 401 through the oil delivery pipe 402 connected to the oil inlet 305. The lubricating oil in the oil storage box 401 is attracted into the cylinder 3041 by the negative pressure.

[0087] During the process of the piston 3042 sliding toward the bottom of the cylinder 3041, the lubricating oil sucked into the cylinder 3041 is ejected through the liquid outlet pipe 3046, and finally acts on the swivel 301, reducing the friction between the swivel 301 and the first through hole 102 or the second through hole 203, which is beneficial to reduce the wear between the moving parts. The movable plate 201 is provided with a baffle 8 located below the oil storage box 401, and the baffle 8 can prevent the first rotating shaft 202 from colliding with the oil storage box 401 when moving up and down.

[0088] When the technicians perform regular maintenance on the suspension wire clamp, they can open the sealing plug 10 on the oil storage box 401 to expose the refueling port at the upper end of the oil storage box 401, so as to check the amount of lubricating oil in the oil storage box 401. When the amount of lubricating oil is insufficient, new lubricating oil can be added to the oil storage box 401. After adding, the sealing plug 10 can be reinserted into the refueling port, and the newly added lubricating oil can continue to lubricate the moving parts.

[0089] This operation process does not require replacement of the entire set of suspension wire clamps, and can continuously lubricate the swivel 301, thereby reducing the cost of use.

[0090] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
