Description

Technical Field

[0001] The invention belongs to the field of line hardware, and in particular relates to a wiring clamp, and also relates to an installation method using the wiring clamp. Background Art

[0002] 10KV line fittings are mainly used on 10KV overhead lines, and their main function is to ensure the safe and stable transmission of electric energy through power lines. These fittings are metal accessories that fix other equipment and wires in the line, also known as iron accessories. In the installation of 10kV pole-mounted transformers, the connection between the lead wire and the main conductor is a key step to ensure the safe and reliable operation of the power system. The lead wire is usually an insulated wire, and the connection between the lead wire and the main conductor should use appropriate connection hardware, such as parallel groove wire clamps and other connection fittings, to ensure good electrical contact and mechanical strength. The number of connection points should not be less than 2 to disperse stress and improve the reliability of the connection. In the above connection method, the high-voltage lead wire is "deadly connected" to the line, which involves the replacement of fuses and lightning arresters under power, etc., which must be completed using the glove method, which has high operation risks and low efficiency.

[0003] In order to solve the above problems, the prior art uses a "live connection" method and adopts an insulating rod operation method to replace fuses, lightning arresters, etc., to improve work efficiency and reduce work risks. However, this method requires a process of tightening the main conductor. Before the main conductor is tightened, the main conductor is easy to fall off from the wiring clamp, which increases the workload and safety hazards. At the same time, due to the elastic deformation caused by changes in the external environment or changes in the conductor load, the wire clamp heats up or even burns.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0005] The present invention aims to design a wiring clamp that can satisfy the structure of "live connection" and solve the problem of fastening the main conductor. Specifically, it provides a wiring clamp, a fastening channel is arranged inside the wiring clamp body, and a partition plate is arranged inside the fastening channel. A push rod and a spring sleeved on the outside of the push rod are arranged on one side of the partition plate. One end of the push rod can pass through the partition plate, and the other end is provided with a rod cap. The rod cap abuts against the wire clamp movable block, and a mounting bolt is arranged on the other side of the partition plate. It can be ensured that when the wire clamp hangs on the main conductor and the mounting bolt is in a loose state, the movable block applies pressure to the main conductor under the action of the spring, so that the wire clamp can be hung on the main conductor and will not slip, thereby overcoming the problem in the prior art that the "live connection" wiring clamp has no fastening force on the main conductor when the mounting bolt is not tightened.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: A wiring clamp comprises a wiring clamp body, on which a lead pressing seat, a lead pressing plate and a wiring clamp movable block are arranged, and the wiring clamp body and the wiring clamp movable block are connected in a lever-type manner, and further comprises: A fastening channel is arranged inside the wire clamp body and penetrates the wire clamp body along the axial direction of the wire clamp body. A partition plate is arranged inside the fastening channel. One side of the partition plate is a bolt cavity and the other side is a push rod cavity. The inner wall of the bolt cavity is provided with threads. A hole is arranged in the middle of the partition plate. A mounting bolt, one end of which is provided with a mounting ring and the other end of which has threads adapted to fit into the bolt cavity; A push rod, the diameter of which is smaller than the hole in the middle of the partition plate, a rod cap is arranged at one end of the push rod away from the partition plate, the diameter of the rod cap is larger than the hole in the middle of the partition plate, and the rod cap abuts against the wire clamp movable block; The spring is sleeved outside the top rod, one end of the spring is in contact with the partition plate, and the other end is in contact with the rod cap.

[0007] Furthermore, a first mounting portion is provided on the wire clamp body, the wire clamp movable block includes a clamping portion and a rotating portion, one end of the rotating portion abuts against the rod cap, a second mounting portion is provided on the rotating portion, and the first mounting portion and the second mounting portion are rotatably connected.

[0008] Furthermore, a first clamping opening is provided at one end of the clamping portion close to the wire clamp body, and the first clamping opening penetrates the clamping portion along a radial direction of the clamping portion.

[0009] Furthermore, a second clamping opening is provided at one end of the wire clamp body close to the clamping portion, and the second clamping opening penetrates the wire clamp body along the radial direction of the wire clamp body and is matched with the first clamping opening.

[0010] Furthermore, the end of the clamping portion away from the rotating portion is arranged to gradually extend from the end of the first clamping opening away from the rotating portion in a direction away from the wire clamp body along the vertical direction of the clamping portion.

[0011] Furthermore, the lead pressing seat and the wire clamp movable block are arranged on the wire clamp body opposite to each other, and the lead pressing seat is provided with a third clamping opening, which extends in the same direction as the second clamping opening.

[0012] Furthermore, a fourth clamping opening is provided on one side of the lead pressing plate close to the lead pressing seat, and the fourth clamping opening has the same extension direction as the second clamping opening and is matched with the third clamping opening.

[0013] Furthermore, it also includes lead pressing sheets, which are arranged at both ends of the lead pressing plate along the direction in which the second clamping opening extends, and the lead pressing plate and the lead pressing sheets are fixedly connected to the lead pressing seat respectively.

[0014] Furthermore, a fifth clamping opening is provided on one side of the lead clamp close to the lead pressing plate, and is matched with the third clamping opening.

[0015] The present invention also provides an installation method based on the above-mentioned wiring clamp, and further, the installation method comprises the following steps: S1. Take out the wiring clamp, completely loosen the mounting bolts, and prepare for installation; S2, install the lead wire stripped of the insulation layer onto the wiring clamp using the lead pressing plate and the lead pressing sheet; S3. Use the mounting hook of the gun operating lever to hook the mounting ring of the mounting bolt, align the movable block of the wiring clamp with the main conductor, and hang it on the main conductor; S4, rotating the mounting hook of the gun operating lever, tightening the mounting bolt, so that the wiring clamp clamps the main conductor; S5. Remove the gun operating lever to complete the installation.

[0016] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: 1. When the wire clamp is hooked on the main conductor and the mounting bolt is still loosened, the loose block exerts pressure on the main conductor under the action of the spring, so that the wire clamp can be hung on the main conductor and will not slip.

[0017] 2. The lever effect formed between the wire clamp movable block and the main conductor can effectively reduce the elastic deformation caused by changes in the external environment or changes in the wire load, which may cause the wire clamp to heat up or even burn.

[0018] 3. The lead pressing plate presses the lead wire with the insulation layer stripped off onto the wire clamp body, and the lead pressing sheet presses the insulation layer of the lead wire to prevent the insulation layer from falling off. BRIEF DESCRIPTION OF THE DRAWINGS

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Embodiment 1 like Figure 1-5 As shown, the present invention provides a wiring clamp, which includes a wiring clamp body 1, on which a lead pressing seat 15, a lead pressing plate 16 and a wiring clamp movable block 2 are arranged.

[0025] Specifically, the wire clamp body 1 and the wire clamp movable block 2 are connected in a lever-like manner, that is, the connection between the wire clamp body 1 and the wire clamp movable block 2 can be regarded as a fulcrum, and the wire clamp movable block 2 can rotate relative to the wire clamp body 1 at the fulcrum.

[0026] Specifically, it also includes a fastening channel 11, which is arranged inside the wire clamp body 1 and penetrates the wire clamp body 1 along the axial direction of the wire clamp body 1. A partition plate 111 is arranged inside the fastening channel 11. One side of the partition plate 111 is a bolt cavity 112, and the other side is a push rod cavity 113. The inner wall of the bolt cavity 112 is provided with a thread, and a hole is arranged in the middle of the partition plate 111. The mounting bolt 12 has a mounting ring 121 at one end and a thread at the other end adapted to fit the bolt cavity 112; The push rod 13 has a diameter smaller than the hole in the middle of the partition plate 111. The end of the push rod 13 away from the partition plate 111 is provided with a rod cap 131. The rod cap 131 has a diameter larger than the hole in the middle of the partition plate 111. The rod cap 131 abuts against the wire clamp block 2. The spring 14 is sleeved outside the top rod 13 , with one end abutting against the partition plate 111 and the other end abutting against the rod cap 131 .

[0027] Specifically, the partition plate 111 extends circumferentially along the inner wall of the fastening channel 11. The shape of the partition plate 111 can be any shape as long as it can reach the separation space and leave a space in the middle for the push rod 13 to pass through. The embodiment of the present application selects a circular ring-shaped partition plate 111, which can withstand greater pressure.

[0028] Specifically, one end of the top rod 13 in the present application can pass through the hole of the partition plate 111, and the other end is provided with a rod cap 131. The rod cap 131 can be of any shape. The rod cap 131 must at least ensure that the top rod 13 cannot pass through the hole in the middle of the partition plate 111, and at the same time ensure that the spring 14 has a force point on the top rod 13. In the embodiment of the present application, the rod cap 131 adopts a circular design. The circular rod cap 131 can make one end of the spring 14 abut against the rod cap 131, thereby increasing the contact area and improving stability.

[0029] Specifically, the spring 14 is selected so that its diameter is larger than the diameter of the hole of the partition plate 111 and smaller than the diameter of the rod cap 131 to ensure that both ends of the spring 14 have force points.

[0030] Preferably, in order to prevent the spring 14 from being displaced during operation and causing the push rod 13 to fall off, a fixing groove can be set at the position where the two ends of the spring 14 abut each other, and the spring 14 can be clamped in the fixing groove to improve stability, or the spring 14 can be fixed by glue or other means at the position where the spring 14 abuts the rod cap 131 and the partition plate 111 to ensure that the spring 14 does not be displaced.

[0031] Preferably, in order to further limit the lateral movement of the top rod 13, as Figure 3 One end of the fastening channel 11 close to the rotating portion 21 is set to be closed, leaving only a space for the rod body part of the push rod 13 to pass through, and the rod cap 131 is placed outside the fastening channel 11. At the same time, between the rod cap 131 and the partition plate 111, a top ring 132 is set along the circumference of the push rod 13 and is set inside the fastening channel 11. One end of the spring 14 abuts against the partition plate 111, and the other end abuts against the top ring 132.

[0032] Specifically, in the above method, the push rod 13 is restricted by the partition plate 111 and the closed end of the fastening channel 11, and will not deviate laterally, thereby increasing its stability. At the same time, since the rod cap 131 is arranged outside the fastening channel 11 and the spring 14 is separated inside the fastening channel 11, the spring 14 loses the force on the push rod 13. Therefore, a top ring 132 is arranged on the part of the push rod 13 inside the fastening channel 11, and the spring 14 is allowed to abut against the top ring 132, so that the push rod 13 as a whole can still be subjected to the elastic force of the spring 14 to meet the demand.

[0033] Specifically, due to the existence of the top ring 132, the vertical movement of the top rod 13 is affected to a certain extent. The distance between the rod cap 131 and the top ring 132 is the vertical movement of the top rod 13. Therefore, the distance between the rod cap 131 and the top ring 132 should be set according to actual conditions. The distance between the rod cap 131 and the top ring 132 can be selected based on the necessary movement required by the clamping part 22.

[0034] Preferably, the top ring 132 can be configured to be movable in the vertical direction of the top rod 13 in the fastening channel 11, so that the distance between the rod cap 131 and the top ring 132 can be adjusted in time according to usage conditions.

[0035] Specifically, in order to realize the vertical movement of the top ring 132 in the top rod 13, the following methods can be adopted: 1. Fasten by screws, specifically, a hole with internal threads is set on the top ring 132, and multiple holes with internal threads are processed on the rod body along the vertical direction. When the top ring 132 is moved to the specified position, align the threaded holes on the rod body and the top ring 132, and screw in a screw to complete the fixation.

[0036] Second, fix it by screwing, specifically, a threaded hole is machined on the side of the top ring 132, and the screw is screwed into the hole. When the top ring 132 is moved to the desired position, the screw is tightened, and the screw head is tightly pressed against the rod body, and the friction between the two is used to fix the collar. Compared with screw tightening, this method can more freely choose the moving position.

[0037] 3. Fixing by a clamp-type structure, specifically, the top ring 132 is composed of two or more parts, which are connected by a clamp-like mechanism, such as bolts and nuts. When fixing is required, the operating mechanism tightens the parts of the ring, thereby clamping the rod body to achieve fixation.

[0038] Specifically, in order to facilitate the fastening operation, the closed part of the fastening channel 11 can be set to be detachable. When the position of the top ring 132 needs to be changed, the closed part is opened, the top rod 13 assembly is taken out, and the top ring 132 is adjusted to a suitable position and fixed. Then, the top rod 13 is partially put back into the fastening channel 11, and finally the closed part is restored to its original state.

[0039] Specifically, a cover is provided, which includes a cover body and a cover edge. The shape of the cover body is adapted to the fastening channel 11, and the cover edge extends from the edge of the cover body in a direction perpendicular to the cover body.

[0040] Specifically, a through hole for accommodating the passage of the push rod 13 is provided in the middle of the main body of the cover, and buckles are evenly arranged along the circumferential direction along the inner wall of the cover. The buckles are elastic and can produce a certain elastic deformation. Relatively speaking, at one end where the fastening channel 11 is connected to the cover, a slot is provided along the circumference of the outer wall of the fastening channel 11 to match the buckle. The buckle is inserted into the slot through elastic deformation, and the cover is snapped into the fastening channel 11 to form a closed part. When you want to remove it, lift the buckle position of the cover to the outside to achieve disassembly and assembly.

[0041] Specifically, the buckle includes two snap-fit ​​surfaces. The snap-fit ​​surface close to the fastening channel 11 is arranged as an inclined surface gradually away from the fastening channel 11 and inclined inwardly, and the snap-fit ​​surface away from the fastening channel 11 is arranged as a straight surface perpendicular to the cover edge, and the two snap-fit ​​surfaces are connected.

[0042] Specifically, a first mounting portion 18 is provided on the wire clamp body 1, and the wire clamp movable block 2 includes a clamping portion 22 and a rotating portion 21, one end of the rotating portion 21 abuts against the rod cap 131, and a second mounting portion 211 is provided on the rotating portion 21, and the first mounting portion 18 and the second mounting portion 211 are rotatably connected.

[0043] Specifically, to achieve the rotatable connection between the first mounting portion 18 and the second mounting portion 211, the following methods may be adopted: 1. Pin connection, mainly composed of cylindrical pins or conical pins, etc., by inserting the pin into the pin hole of the connected part to achieve a rotatable connection between the two parts. There is a small amount of interference fit between the pin and the pin hole, allowing the parts to rotate relative to each other. The pin connection has a simple structure, low cost and easy installation. However, it can withstand relatively small loads and has limited positioning capabilities for precise rotation.

[0044] Specifically, the wiring clamp includes a cylindrical pin, and pin holes matching the cylindrical pin are respectively provided on the first mounting portion 18 and the second mounting portion 211. When the wiring clamp body 1 and the wiring clamp movable block 2 are installed, the pin hole on the first mounting portion 18 is aligned with the pin hole on the second mounting portion 211, and then the cylindrical pin is inserted into the pin hole. The cylindrical pin and the pin hole are slightly interfered with each other, so that the connection part can be rotated while achieving a fixing effect.

[0045] 2. Bearing connection, composed of inner ring, outer ring, rolling element and cage. The inner ring usually matches with the shaft, the outer ring matches with the hole of the bearing seat or mechanical parts, the rolling element rolls between the inner and outer rings, and the cage ensures the uniform distribution of the rolling element, reduces friction and wear, and enables the shaft to rotate smoothly under the support of the bearing.

[0046] Specifically, the terminal clamp includes a bearing, and the bearing is arranged on one of the first mounting portion 18 and the second mounting portion 211: When the bearing is arranged on the first mounting part 18, the first mounting part 18 is provided with a through hole, the diameter of which is adapted to the diameter of the outer ring of the bearing, and the outer ring of the bearing abuts against the inner wall of the through hole to form an interference fit for fixation; the second mounting part 211 is provided with an inserted shaft, the diameter of which is adapted to the diameter of the inner ring of the bearing and is perpendicular to the end face of the second mounting part 211.

[0047] When the bearing is arranged on the second mounting part 211, the second mounting part 211 is provided with a through hole, the diameter of which is adapted to the diameter of the outer ring of the bearing, and the outer ring of the bearing abuts against the inner wall of the through hole to form an interference fit for fixation; the first mounting part 18 is provided with an inserted shaft, the diameter of which is adapted to the diameter of the inner ring of the bearing and is perpendicular to the end face of the first mounting part 18.

[0048] Specifically, during installation, the insertion shaft is inserted into the inner ring of the bearing to form an interference fit, thereby achieving a fixing effect and realizing the rotatable function of the connecting part.

[0049] Specifically, there are many ways to achieve the rotatable connection between the first mounting portion 18 and the second mounting portion 211 , and a suitable structure can be selected according to actual conditions.

[0050] Specifically, through the above arrangement, the push rod 13 can also apply pressure to the wire clamp movable block 2 under the action of the spring 14 when the mounting bolt 12 is not tightened, so that the clamping part 22 is subjected to a force in the direction of the wire clamp body 1 through a lever.

[0051] Specifically, a first clamping opening 221 is provided at one end of the clamping portion 22 of the wire clamp movable block 2 close to the wire clamp body 1, and the first clamping opening 221 penetrates the clamping portion 22 along the radial direction of the clamping portion 22; a second clamping opening 17 is provided at one end of the wire clamp body 1 close to the clamping portion 22, and the second clamping opening 17 penetrates the wire clamp body 1 along the radial direction of the wire clamp body 1 and is adapted to the first clamping opening 221.

[0052] Specifically, when the clamping portion 22 approaches the wire clamp body 1, the first clamping opening 221 and the second clamping opening 17 are opposite to each other, forming a quasi-circular space for clamping the main wire.

[0053] Specifically, due to the presence of the push rod 13 and the spring 14, even if the mounting bolt 12 is not tightened, the spring 14 will give the push rod 13 an outward force, and the force will be transmitted to the rotating part 21 through the push rod 13, and the rotating part 21 will transmit it to the clamping part 22 through the lever structure, so that the clamping part 22 is subjected to a force in the direction of the wire clamp body 1. When the main wire is between the first clamping port 221 and the second clamping port 17, it is subjected to the force from the clamping part 22, so that it is fixed and does not fall off.

[0054] Specifically, the end of the clamping portion 22 away from the rotating portion 21 is configured to gradually extend along the vertical direction of the clamping portion 22 from the end of the first clamping opening 221 away from the rotating portion 21 toward the direction away from the wire clamp body 1. From the cross-sectional view, the end of the clamping portion 22 away from the rotating portion 21 forms a right-angled trapezoid with the wire clamp body 1, which makes it easier to hang the wiring clamp on the main conductor.

[0055] Specifically, during the installation process, hanging the terminal clamp on the main conductor requires that the position of the first clamping port 221 or the second clamping port 17 be aligned with the main conductor. However, in actual operation, it is rare for the alignment to be successful at one time, which reduces work efficiency and increases safety hazards. The clamping portion 22 is designed to be a structure with a beveled edge. During operation, even if the first clamping portion 22 or the second clamping portion 22 is not aligned, as long as the main conductor contacts the beveled portion of the clamping portion 22, the beveled edge of the clamping portion 22 will guide the main conductor to the position of the first clamping port 221 or the second clamping port 17. The beveled edge of the clamping portion 22 is larger and easier to find and contact, which not only improves installation efficiency but also reduces safety hazards.

[0056] Specifically, in actual use, in addition to preventing the main conductor from falling off, it is also necessary to avoid the situation where the terminal clamps heat up or even burn due to elastic deformation caused by changes in the external environment or changes in the conductor load.

[0057] Specifically, the elastic deformation of the main conductor causes the heating of the terminal clamp because, when the external environment (such as a significant change in temperature) or the conductor load changes, the contact state between the clamp block 2 and the main conductor changes due to elastic deformation, and the originally tightly contacted parts may become loose or the contact area may decrease. According to the resistance law R=ρ (where R is resistance, ρ is resistivity, L is conductor length, and S is conductor cross-sectional area). When the contact area S decreases, the contact resistance will increase, which will in turn aggravate the thermal effect of the current. According to Joule's law: Q=I²Rt (where Q is heat, I is current, R is resistance, and t is time), when the current I and time t remain unchanged, the contact resistance R increases, which will lead to an increase in the amount of heat Q generated per unit time, thereby increasing the temperature of the terminal clamp. The increase in the temperature of the terminal clamp will further affect the physical properties of the terminal clamp and the main conductor, which may aggravate the elastic deformation, leading to a further increase in contact resistance, forming a vicious cycle, and may eventually cause the terminal clamp to burn due to overheating.

[0058] Specifically, in the embodiment of the present invention, during the tightening process of the mounting bolt 12, one end of the push rod 13 passing through the hole of the partition plate 111 will abut against the mounting bolt 12, and the mounting bolt 12 will lift the push rod 13 upward, so that the main conductor is firmly clamped between the first clamping port 221 and the second clamping port 17. When the main conductor undergoes elastic deformation, the contact between the main conductor and the clamping portion 22 becomes loose. Under normal circumstances, the mounting bolt 12 is already fixed at this time and can no longer provide an upward force to the push rod 13. Due to the presence of the spring 14 in the present invention, an upward force can still be provided to the push rod 13 at this time, so that the clamping portion 22 can still keep the main conductor tight, thereby avoiding the increase of contact resistance due to the reduction of contact area, thereby aggravating the thermal effect of the current and causing the terminal clamp to heat up.

[0059] Specifically, the lead press seat 15 and the wire clamp movable block 2 are arranged on the wire clamp body 1 opposite to each other, and the lead press seat 15 is provided with a third clamping opening 151, which extends in the same direction as the second clamping opening 17; a fourth clamping opening 162 is provided on the side of the lead pressure plate 16 close to the lead press seat 15, and the fourth clamping opening 162 has the same extension direction as the second clamping opening 17 and is adapted to the third clamping opening 151.

[0060] Specifically, the fourth clamping hole 162 and the third clamping hole 151 are used together to fix the lead wire. The fourth clamping hole 162 and the third clamping hole 151 are set to have the same extension direction as the second clamping hole 17, so that the extension lines of the lead wire and the main wire can be the same, which helps to make the distribution of the magnetic field generated by the current more regular and reduce the distortion and mutual interference of the magnetic field.

[0061] Specifically, it also includes lead pressing pieces 161 , which are arranged at both ends of the lead pressing plate 16 along the extending direction of the second clamping opening 17 , and the lead pressing plate 16 and the lead pressing piece 161 are fixedly connected to the lead pressing seat 15 , respectively.

[0062] Specifically, the lead pressing plate 16 and the lead pressing sheet 161 are used to fix the lead on the wire clamp body 1, wherein the lead pressing plate 16 presses the lead wire with the stripped insulation layer onto the wire clamp body 1, and the lead pressing sheet 161 mainly presses the insulation layer of the lead wire to prevent it from falling off.

[0063] Specifically, a fifth clamping opening 163 is provided on one side of the lead clamp close to the lead pressing plate 16 , which is matched with the third clamping opening 151 and is used for clamping the lead.

[0064] Embodiment 2 This embodiment provides an installation method for a wiring clamp, which is applicable to the wiring clamp in Embodiment 1, but is not limited to the wiring clamp in Embodiment 1. Specifically, a shooting gun operating rod is used, and the shooting gun operating rod includes: an operating main rod and a mounting hook arranged at one end of the operating main rod, and the diameter of the mounting hook is smaller than the inner circle diameter of the mounting ring 121; a fixed cover, which is sleeved on the end of the operating main rod where the mounting hook is arranged.
