Description

Technical Field

[0001] This invention relates to the field of overhead power line installation, and more particularly to the field of conductor fixing clamps. Background Technology

[0002] Porcelain insulators are commonly used to secure high-voltage conductors, with the conductor tightly fitted against the insulator's groove. Traditionally, wire ties were used to bind the conductor to the insulator, but this method is inefficient, prone to loosening or even detachment over time, and the ties, typically made of metal wire directly wrapped around the conductor's sheath, can damage the sheath and create a risk of overheating and electrical leakage. To replace this binding method, various wire tensioners have emerged on the market to work with porcelain insulators and secure the conductor.

[0003] Application No. 201910256666.6 provides a double-sided open cable tensioner. A locking nut is provided on both the first and second screws. Tightening the locking nut allows the pressure plate to move towards the pin insulator, thereby pressing the cable firmly onto the top groove of the pin insulator. This clamping method requires simultaneously tightening the nuts on both sides to ensure their relative height is consistent, making the operation cumbersome and inefficient.

[0004] Application No. 202021546346.9 discloses a cable tensioner, in which a second clamping plate is used to cooperate with a first clamping plate to clamp an insulating porcelain insulator. The second clamping plate is located between the first clamping plate and a pressure plate. The other end of the second clamping plate has a slot for a first screw to pass through. An opening is provided on the outside of the slot so that when the second clamping plate rotates around the second screw, the first screw disengages from the slot through the opening. This method of clamping the porcelain insulator increases the original clamping diameter, thus reducing the clamping effect. Summary of the Invention

[0005] The purpose of this invention is to provide a wire fixing clamp to solve one or more of the above-mentioned problems.

[0006] According to one aspect of the present invention, a wire fixing clamp is provided, comprising an upper pressure plate, a first clamping plate and a second clamping plate, characterized in that: one end of the first clamping plate is hinged to one end of the second clamping plate, and the first clamping plate and the second clamping plate are rotatably open and close;

[0007] One end of the upper pressure plate is hinged to a first rod, the free end of the first rod is vertically disposed at the hinge point between the first clamping plate and the second clamping plate, the upper pressure plate can reciprocate relative to the first clamping plate and the second clamping plate, and the other end of the upper pressure plate is provided with a locking part;

[0008] The free end of the first clamping plate is provided with an adjustment groove, and the free end of the second clamping plate is hinged with a second rod that cooperates with the adjustment groove. The free end of the second rod is provided with a clamping member that cooperates with the clamping part.

[0009] Therefore, the present invention provides a compact and portable wire fixing clamp with an integrated clamp design, so there is no need to worry about parts falling off when used at heights; the clamping diameter of the first and second clamping plates is adjustable to accommodate insulators of different specifications; when tightening, only one end of the upper pressure plate needs to be adjusted, without the need to tighten both ends at the same time.

[0010] In some embodiments, the free end of the first rod is threaded, and the hinge of the second clamping plate is threaded to match the free end of the first rod. Rotating the first rod adjusts the position of the upper pressure plate relative to the second clamping plate. This allows for pre-adjustment of the position of the upper pressure plate relative to the first and second clamping plates.

[0011] In some embodiments, the first clamp and the second clamp are on the same plane, so that the first clamp and the second clamp can be subjected to force evenly, thereby increasing the strength of the clamp.

[0012] In some embodiments, the hinged end of the first clamping plate is provided with a first clamping groove, and the hinged end of the second clamping plate is provided with a first clamping member that matches the first clamping groove; the free end of the second clamping plate is provided with a second clamping groove, and the free end of the first clamping plate is provided with a second clamping member that matches the second clamping groove.

[0013] When the first clamping plate and the second clamping plate rotate relative to each other and approach each other, the first clamping member inserts into the first clamping groove, and the second clamping member partially inserts into the second clamping groove. This clamping structure at the connection between the first and second clamping plates further increases the strength of the wire clamp.

[0014] In some embodiments, the free end of the first clamping plate extends to be provided with an adjustment seat, the adjustment seat being provided with a plurality of adjustment slots; the free end of the second clamping plate extends to be provided with a rod seat, the rod seat being hinged to the second rod.

[0015] When the first clamping plate and the second clamping plate rotate relative to each other until the adjusting groove is directly opposite the second rod, the second rod can rotate into the adjusting groove. This allows the clamping diameter of the wire clamp to be adjusted according to the diameter of the porcelain insulator, ensuring a tight fit.

[0016] In some embodiments, the clamping part includes a groove disposed at the end of the upper pressure plate; the clamping element includes a nut that threadedly engages with the second rod; when the upper pressure plate is rotated downward to a suitable position, the second rod can rotate into the groove, and tightening the nut can fix the upper pressure plate; the outer surface of the nut is fitted with an arc-shaped wrench symmetrical about the nut. This provides a specific clamping method that can be operated by hand, increasing the convenience of using the wire clamp.

[0017] In some embodiments, arc-shaped protrusions are provided at both ends of the slot to prevent the second rod from slipping off.

[0018] In some embodiments, the hinge end of the first rod is provided with a hinge hole, and the hinge end of the upper pressure plate is provided with a hinge groove and hinge holes on both sides of the hinge groove. The hinge end of the first rod is disposed in the hinge groove of the upper pressure plate, and the hinge hole of the first rod and the hinge hole of the upper pressure plate correspond to each other and are connected by a first pin. This provides a specific hinge connection method between the first rod and the upper pressure plate.

[0019] In some embodiments, the hinged end of the second rod is provided with a hinge hole, and the rod seat is provided with a hinge groove and hinge holes on both sides of the hinge groove of the rod seat. The hinged end of the second rod is disposed in the hinge groove of the rod seat, and the hinge hole of the second rod and the hinge hole of the rod seat correspond to each other and are connected by a second pin. This provides a specific hinged connection method between the second rod and the second clamping plate.

[0020] In some embodiments, the upper pressure plate is provided with a removable gasket, and the side of the gasket facing the wire has multiple parallel protrusions. This allows for the selection of a suitable gasket according to the wire specifications, improving the clamping effect. Attached Figure Description

[0022] Figure 2 This is a schematic diagram of the structure of one embodiment of the present invention;

[0023] Figure 3 This is a schematic diagram illustrating the use of one embodiment of the present invention. Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 and Figure 2 The wire clamp shown includes an upper pressure plate 3, a first clamping plate 1, and a second clamping plate 2. Figure 3As shown, the first clamping plate 1 and the second clamping plate 2 cooperate to clamp the head of the porcelain insulator 7, placing the conductor 6 into the groove of the head of the porcelain insulator 7. The upper pressure plate 3 presses down on the conductor 6 and locks it in place, thus fixing the conductor 6. A removable gasket 31 is provided at the contact point between the upper pressure plate 3 and the conductor 6. The gasket 31 is available in different models according to the specifications of the conductor 6 and can be replaced as needed. The side of the gasket 31 facing the conductor 6 has multiple parallel protrusions, thereby improving the fixing and clamping effect.

[0026] The first clamping plate 1 and the second clamping plate 2 are respectively semi-circular arcs. One end of the first clamping plate 1 is hinged to one end of the second clamping plate 2. A first clamping groove 11 is provided at the hinged end of the first clamping plate 1, and a first clamping member 21 matching the first clamping groove 11 is provided at the hinged end of the second clamping plate 2. A second clamping groove 22 is provided at the free end of the second clamping plate 2, and a second clamping member 12 matching the second clamping groove 22 is provided at the free end of the first clamping plate 1.

[0027] When the first clamping plate 1 and the second clamping plate 2 rotate toward each other, the first clamping member 21 is inserted into the first clamping groove 11, and the second clamping member 12 is partially inserted into the second clamping groove 22, so that the first clamping plate 1 and the second clamping plate 2 can rotate and open and close in the same plane without misalignment. Furthermore, the clamping structure at both ends of the first clamping plate 1 and the second clamping plate 2 further strengthens the overall strength of the wire clamp.

[0028] One end of the upper pressure plate 3 is hinged to a first rod 4. The hinged end of the first rod 4 has a hinge hole, and the hinged end of the upper pressure plate 3 has a hinge groove and hinge holes on both sides of the hinge groove. The hinged end of the first rod 4 is located in the hinge groove of the upper pressure plate 3. The hinge hole of the first rod 4 corresponds to the hinge hole of the upper pressure plate 3 and is connected by a first pin 15. This allows the upper pressure plate 3 to reciprocate around the first pin 15 relative to the surfaces of the first clamping plate 1 and the second clamping plate 2. The free end of the first rod 4 is threaded and is perpendicularly located at the hinge point between the first clamping plate 1 and the second clamping plate 2. The hinge point of the second clamping plate 2 is threaded to match the free end of the first rod 4, thus achieving a threaded connection between the first rod 4 and the second clamping plate 2. Rotating the first rod 4 adjusts the position of the upper pressure plate 3 relative to the second clamping plate 2.

[0029] In some embodiments, the first rod 4 is a hinge bolt, and the pin passes through the hole of the hinge bolt and the hinge hole of the hinge end of the upper pressure plate 3, thereby realizing the hinge connection between the first rod 4 and the upper pressure plate 3; the threaded part of the hinge bolt is threadedly connected to the second clamping plate 2.

[0030] An adjustment seat 13 extends from the free end of the first clamping plate 1. The adjustment seat 13 has three adjustment slots 14, which can adjust the relative distance between the first clamping plate 1 and the second clamping plate 2 according to different sizes of porcelain insulators 7, thereby achieving a tight fit with the porcelain insulators 7. A rod seat 23 extends from the free end of the second clamping plate 2. A second rod 5 that mates with the adjustment slots 14 is hinged to the rod seat 23. The hinged end of the second rod 5 has a hinge hole. The rod seat 23 has a hinge slot and hinge holes on both sides of the hinge slot. The hinged end of the second rod 5 is located in the hinge slot of the rod seat 23. The hinge holes of the second rod 5 and the hinge holes of the rod seat 23 correspond to each other and are connected by a second pin 24.

[0031] The other end of the upper pressure plate 3 is provided with a clamping part 32, which includes a groove 321 located at the end of the upper pressure plate 3. The free end of the second rod 5 is provided with a clamping member 51 that cooperates with the clamping part 32. The clamping member 51 includes a nut 511 that is threadedly engaged with the second rod 5. The outer surface of the nut 511 is fixedly fitted with an arc-shaped wrench 512 symmetrical about the nut 511, which makes it convenient for workers to tighten the nut 511 by hand.

[0032] When the first clamping plate 1 and the second clamping plate 2 rotate relative to each other until the appropriate adjustment groove 14 is aligned with the second rod 5, and the upper pressure plate 3 rotates downwards to contact the wire 6, rotate the second rod 5 so that both ends of the second rod 5 enter the adjustment groove 14 and the locking groove 321 respectively. Tightening the nut 511 will simultaneously fix the first clamping plate 1, the second clamping plate 2, and the upper pressure plate 3. To prevent the second rod 5 from slipping, arc-shaped protrusions 322 are provided at both ends of the locking groove 321.

[0033] In some embodiments, the second rod 5 is a hinge bolt, and the pin passes through the hole of the hinge bolt and the hinge hole of the rod seat 23 to achieve the hinge connection between the second rod 5 and the rod seat 23; the threaded portion of the hinge bolt is threadedly connected to the nut 511.

[0034] When using this clamp, the distance between the upper pressure plate 3 and the second clamp 2 should be adjusted by rotating the first rod 4 according to the specifications of the conductor 6. After adjustment, the clamping part 32 should be aligned with the clamping member 51. Rotate the first clamp 1 closer to the second clamp 2 to clamp the porcelain insulator 7 and select a suitable adjustment groove 14. At the same time, rotate the upper pressure plate 3 to press the conductor 6 in the slot of the porcelain insulator 7. Rotate the second rod 5 so that the second rod 5 enters the adjustment groove 14 to fix the first clamp 1 and the second clamp 2. Then, through the cooperation of the clamping part 32 and the clamping member 51, tighten the nut 511 by hand to make the upper pressure plate 3 press the conductor 6.

[0035] In summary, this invention provides a compact and portable wire fixing clamp; the integrated clamp design eliminates concerns about parts falling off when used at heights; the clamping diameters of the first and second clamping plates are adjustable to accommodate insulators of different specifications; the height of the upper pressure plate and the shims are adjustable to accommodate wires of different diameters.

[0036] The above description is only one embodiment of the present invention. It should be noted that for those skilled in the art, several similar modifications and improvements can be made without departing from the inventive concept of the present invention, and these should also be considered within the protection scope of the present invention.
