Description

Technical Field

[0001] This invention belongs to the technical field of power distribution line operation tools, specifically relating to a complete set of C-type clamp installation tools and methods for live-line operation in power distribution networks. Background Technology

[0002] With the rapid development of society and the economy, the requirements for power reliability are becoming increasingly stringent. Ensuring continuous and uninterrupted power supply is a basic requirement for electricity in all sectors of the national economy. Power supply reliability has become an important performance indicator for power supply companies, making it imperative to improve it. Adhering to the principle of "maintaining power without interruption" and using live-line working instead of power outage work for distribution network maintenance is currently the mainstream trend in maintenance work. This approach not only improves reliability but also generates significant economic and social benefits.

[0003] Live-line splicing using insulated gloves is a common operation in live-line work. C-clamps are one of the most frequently used hardware for splicing conductors in overhead power lines. The conventional method for live-line splicing using C-clamps is as follows: the worker stands inside an insulated container and first strips the insulation of the main conductor (insulated wire) at a suitable position, slightly longer than two lengths, and hooks the clamp. After securing the lead wire, one end of the lead wire (insulated wire) is stripped to the same length as the main conductor. Then, a C-clamp is installed on the main conductor. Holding the C-clamp on the main conductor with one hand and the lead wire with the other, the worker quickly inserts the lead wire end into the C-clamp on the main conductor, tightens the clamp screw, and then installs the second C-clamp. Due to the small size and difficulty in opening the C-clamp's hole, poor stability at heights, and limited working position, the worker may sometimes need to perform multiple operations to successfully insert the lead wire into the C-clamp.

[0004] The drawback of this method is that when workers simultaneously grasp the C-clamp of the main conductor and the lead wire, their bodies become intertwined with the live circuit. Although workers wear insulated gloves, according to the Technical Guidelines for Live Working on Distribution Lines (GBT18857-2019), insulated gloves are only auxiliary insulation and cannot provide primary protection for the human body. Therefore, there is a certain risk of electric shock if the human body enters the circuit. Secondly, an electric arc will be generated the moment the lead wire is connected to the main conductor, which will also threaten the safety of workers. Therefore, how to avoid human body entry into the circuit, repeated operations, and electric arc injuries during the process of connecting the lead wire with a C-clamp while it is live is a technical problem that needs to be solved. Summary of the Invention

[0005] In order to solve the above problems, according to some embodiments, the present invention adopts the following technical solution:

[0006] In a first aspect, the present invention provides a complete set of C-type clamp installation tools for live-line work in power distribution networks, comprising: a clamp fixing device and a C-type clamp body, wherein the C-type clamp body is used to connect the main line and the lead wire; the clamp fixing device includes a device body structure, a lead wire clamping unit, a main line locking mechanism and a clamping mechanism.

[0007] The clamping mechanism is installed on one side of the device body structure and is used to clamp the C-type wire clamp body;

[0008] The lead wire clamping unit is installed in the middle of the device body structure. The lead wire clamping unit includes lead wire jaws, which are located on the left and right sides of the clamping mechanism and are used to clamp the lead wire.

[0009] The main line locking mechanism is installed on the upper part of the device body structure and above the lead wire clamping unit, and is used to lock the main line.

[0010] Furthermore, the clamping mechanism includes an upper clamping mechanism and a lower support limiting member. The upper clamping mechanism is installed on the top of the device body structure, and the lower support limiting member is installed in the middle of the device body structure. The upper clamping mechanism and the lower support limiting member cooperate to clamp the C-type clamp body.

[0011] Furthermore, the main body structure of the device includes a main body structural component and a structural connector. The main body structural component and the lower end support and limiting component of the wire clamp are installed on the upper surface of the structural connector. The structural connector is also provided with a transmission rod mounting hole for installing a helical transmission rod.

[0012] Furthermore, the lead wire clamping unit includes lead wire jaws, a spiral drive rod, and an insulating handle. The insulating handle is installed on the bottom surface of the lead wire clamping device. The insulating handle is fixedly connected to the spiral drive rod, and the spiral drive rod is rotatably connected to the lead wire jaws. The spiral drive rod can drive the lead wire jaws to move up and down, thereby achieving self-locking clamping of the lead wire.

[0013] Furthermore, the main line locking mechanism includes a locking mechanism body structure, which includes a connecting plate and a first convex structural block and a second convex structural block. The first convex structural block is disposed at one end of the connecting plate, and the second convex structural block is disposed at the other end of the connecting plate.

[0014] Secondly, the present invention improves the working method of a complete set of C-type clamp installation tools for live-line work in distribution networks as described in the first aspect, comprising:

[0015] The C-type wire clamp body is clamped and fixed by the clamping mechanism;

[0016] The main line is locked and fixed to the inner upper surface of the C-type wire clamp body using the main line locking mechanism;

[0017] The lead wire is clamped and fixed to the lower inner surface of the C-type wire clamp body using the lead wire clamping unit;

[0018] Place the C-type wire clamp wedge into the C-type wire clamp bolt;

[0019] Screw the spring ball plunger-type special sleeve, which has been fitted with nuts, spring washers and flat washers, into the C-type wire clamp bolt and tighten it so that the C-type wire clamp body crimps the lead wire and the main wire.

[0020] Disconnect the clamp body fixing tool unit from the C-type clamp body to complete the entire wiring process.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. The C-type wire clamp installation tool of this invention consists of two parts. One part is a wire clamp fixing device. First, this device is used to fix the C-type wire clamp body and bolts. Then, the lead wire to be connected is clamped and fixed in the lower slot of the C-type wire clamp body. Next, the main wire is clamped into the upper slot of the C-type wire clamp body by holding the device. This operation achieves temporary conductivity between the lead wire to be connected and the main wire, preventing the operator from touching the main wire and the unconnected lead wire at the same time and thus avoiding electric shock. At this time, the hands are freed, and the main wire and the lead wire maintain a fixed distance, which greatly facilitates the installation of the C-type wire clamp wedge and nut. The other part is a special spring ball plunger type sleeve. The spring ball plunger structure allows the nut, spring washer and flat washer to be inserted in sequence and screwed into the C-type wire clamp bolt as a combination, improving the safety of operation. Using this tool to replace manual connection of live wires effectively prevents the operator from entering the circuit and avoids the risk of electric shock. It also ensures a safe distance between the operator and the live conductor and avoids the operator from being injured by electric arc.

[0023] 2. This invention uses a clamping mechanism to clamp and fix the C-type wire clamp body; the main wire is clamped and fixed to the upper inner surface of the C-type wire clamp body using a main wire locking mechanism; the lead wire is clamped and fixed to the lower inner surface of the C-type wire clamp body using a lead wire clamping unit; the C-type wire clamp wedge is placed onto the C-type wire clamp bolt; a spring ball plunger-type special sleeve with nuts, spring washers, and flat washers installed is screwed into the C-type wire clamp bolt and tightened, so that the C-type wire clamp body crimps the lead wire and the main wire; the wire clamp body fixing tool unit is disengaged from the C-type wire clamp body, completing the entire wiring process and improving work efficiency. Using this tool to connect live leads simplifies the work process, avoids repeated operations due to lack of skill, reduces work time, improves both work safety and efficiency, and solves problems such as human body entering the circuit, repeated operations, and arc injuries during live lead connection using C-type wire clamps.

Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0033] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0034] Example 1:

[0035] like Figures 1-2 As shown, this embodiment provides a complete set of C-type clamp installation tools for live-line work in power distribution networks, including: a clamp fixing device 8 and a C-type clamp body 6; the clamp fixing device 8 includes a device body structure 1, a lead wire clamping unit, a main line locking mechanism 3, and a clamping mechanism.

[0036] The clamping mechanism is installed on one side of the device body structure 1 and is used to clamp the C-type wire clamp body 6. The C-type wire clamp body 6 is used to connect the main line 9 and the lead line 7.

[0037] The lead wire clamping unit is installed in the middle of the main body structure 1 of the device. The lead wire clamping unit includes lead wire clamps 2-1, which are located on the left and right sides of the clamping mechanism and are used to clamp the lead wire.

[0038] The main line locking mechanism 3 is installed on the main body structure 1 of the device and is located above the lead wire clamping unit, and is used to lock the main line 9.

[0039] The clamping mechanism includes an upper clamping mechanism 4 and a lower support and limiting member 1-3. The upper clamping mechanism 4 is installed on the top of the device body structure 1, and the lower support and limiting member 1-3 is installed in the middle of the device body structure 1. The upper clamping mechanism 4 and the lower support and limiting member 1-3 cooperate to clamp the C-type clamp body 6.

[0040] The main body structure 1 of the device includes a main body structural component 1-1, a structural connector 1-2, and a lower end support and limiting component 1-3 for the wire clamp. The structural connector 1-2 connects the main body structural component 1-1 and the lower end support and limiting component 1-3 for the wire clamp, and at the same time provides a shaft end limit for the screw drive rod 2-2. The lower end support and limiting component 1-3 for the wire clamp is used to limit the lower end of the C-type wire clamp body 6, and cooperates with the upper end clamping mechanism 4 of the wire clamp to clamp the C-type wire clamp body 6.

[0041] The main structural component 1-1 includes a rectangular mounting block and a rectangular mounting plate. The rectangular mounting plate is set on the top surface of the rectangular mounting block. One side of the rectangular mounting block is provided with a groove, in which a lead wire clamping mechanism 2 is installed. The bottom of the rectangular block is installed on the upper surface of the structural connector 1-2. The rectangular mounting plate and the groove are provided with a first mounting hole on the same side. The first mounting hole is used to install the upper clamping mechanism 4 of the wire clamp. The rectangular mounting plate and the groove are provided with a second mounting hole on the back side. The second mounting hole is used to install the main wire locking mechanism 3.

[0042] The structural connector 1-2 is a rectangular plate structure. The main body structural component 1-1 is installed on one side of the upper surface of the structural connector 1-2, and the lower end support and limiting component 1-3 of the wire clamp is installed on the other side of the upper surface. The lower end support and limiting component 1-3 of the wire clamp and the upper end clamping mechanism 4 of the wire clamp are on the same plane and aligned vertically, so as to clamp the C-type wire clamp body 6.

[0043] The lower support of the wire clamp is a rectangular block structure with an arc surface on the upper end. The arc surface matches the arc shape of the C-type wire clamp body 6, thus supporting the C-type wire clamp body 6.

[0044] The lead wire clamping unit includes lead wire grippers 2-1, a screw drive rod 2-2, and an insulated handle 2-3. The insulated handle 2-3 facilitates gripping by operators while avoiding direct contact with live parts. It is fixedly connected to the screw drive rod 2-2, and its rotation drives the screw drive rod 2-2 to rotate synchronously, thereby causing the lead wire grippers 2-1 to move up and down, achieving a self-locking clamping of the lead wire 7 and preventing the lead wire 7 from slipping out of the tool under traction. The lead wire grippers 2-1 are guided by the main structure of the device and driven by the screw drive rod 2-2 to move up and down. Together with the C-type wire clamp body 6, they clamp the lead wire 7 and then pull the lead wire 7 to the position of the main line 9 to be connected.

[0045] The linear gripper includes a rectangular mounting block and an arc-shaped clamping part. The rectangular mounting block is mounted on the helical drive rod 2-2. The rotation of the helical drive rod 2-2 drives the linear gripper to move along the groove of the main body structure 1-1. The arc-shaped clamping part is located on the side of the rectangular mounting block. The end of the arc-shaped clamping part has an arc-shaped structure, which matches the structure of the lead wire 7 and clamps the lead wire 7.

[0046] The main line locking mechanism 3 can lock the main line 9, preventing the tool from sliding or falling off the main line 9 under the pulling force of the lead wire. It includes several parts such as the locking mechanism body structure 3-1, the first handle 3-2, the first locking tongue 3-3, the second locking tongue 3-4, and the second handle 3-5. The locking mechanism body structure 3-1 is fixed to the device body structure 1. The first locking tongue 3-3 and the second locking tongue 3-4 are guided by the body structure and kept in an extended, ready state under the action of springs. The first handle 3-2 is connected to the first locking tongue 3-3 and the second locking tongue 3-4, allowing the operator to pull the first locking tongue 3-3 and the second locking tongue 3-5. Tongue 3-4 retracts to adjust the position of the tool on the main line 9; the second handle 3-5 can lock the first and second locking tongues 3-3 and 3-4 after they retract, making it easier to place the tool on the main line 9. This mechanism can be disassembled as needed. If it is removed, it will not affect the overall function, but will only have a certain impact on the main line 9 being inserted into the C-shaped body of the C-type clamp. After the second handle 3-5 is removed, when the main line 9 is inserted into the C-shaped body of the C-type clamp, the operator needs to press the locking tongue in forcefully. The locking tongue will retract under the pressure and automatically rebound under the elastic force of the spring, thus locking the main line 9.

[0047] In one embodiment, the locking mechanism body structure 3-1 includes a connecting plate and a first convex structural block and a second convex structural block. The first convex structural block is disposed at one end of the connecting plate, and the second convex structural block is disposed at the other end of the connecting plate. The middle part of the connecting plate is mounted on a rectangular mounting plate of the body structure 1-1. Multiple second mounting holes can be provided on the rectangular mounting plate to adjust the mounting position of the locking mechanism body structure 3-1 as needed.

[0048] The lower part of the first convex structural block has a horizontally penetrating first hole for installing a first locking tongue 3-3. One end of the first locking tongue 3-3 is provided with a first handle 3-2. The upper part of the first convex structural block has a vertically penetrating second hole for installing fasteners, which can be used to fix the position of the first locking tongue 3-3. The structure of the second convex structural block is the same as that of the first convex structural block, and will not be described again here.

[0049] The upper clamping mechanism 4, under the action of the extending clamping tongue 4-4, clamps the C-type wire clamp body 6 placed inside the tool, preventing it from falling out of the tool and forming an assembly with the tool. The upper clamping mechanism 4 consists of several parts, including the clamping mechanism body 4-1, the pull pin 4-2, the reset push rod 4-3, and the clamping tongue 4-4. The clamping mechanism body 4-1 is bolted to the main body structure 1 of the device, providing a guide surface for the clamping tongue 4-4; the pull pin 4-2 is fixed to the clamping mechanism body 4-1, and after the clamping tongue 4-4 retracts, it fixes the clamping tongue 4-4 in the retracted state, facilitating the smooth insertion of the C-type wire clamp body 6 into the main body structure 1 of the device. After the C-type wire clamp body 6 is inserted into the main body structure 1 of the device, pulling the pull pin 4-2 causes the clamping tongue 4-4 to pop out and fix the C-type wire clamp body 6 into the main body structure 1 of the device, forming a tool and wire clamp assembly.

[0050] In one embodiment, the upper clamping mechanism 4 of the wire clamp includes a clamping mechanism body 4-1, a pull pin 4-2, a reset push rod 4-3, and a clamping tongue 4-4. The clamping mechanism body 4-1 has a rectangular structure with a groove at its bottom. The clamping tongue 4-4 is installed in the groove. One end of the clamping tongue 4-4 is connected to the reset push rod 4-3, and the other end extends out of the clamping mechanism body 4-1 to limit the C-type wire clamp body 6. The pull pin 4-2 is fixed to one side of the clamping mechanism body 4-1 to fix the clamping tongue 4-4.

[0051] The C-type clamp body 6 can be a Keyi JC-2 model C-type clamp. Hang the C-type component and the downlead on the main line. Insert the sub-clamp into the main clamp at a certain angle. Place the assembled clamp between the conductors, and then install the clamp bolt 5, adjusting washer, spring washer, and nut in sequence. Tighten with a socket or wrench until the clamp is flattened, completing the installation. The clamp bolt 5 and the C-type clamp body 6 are inherent structural components of the C-type clamp.

[0052] As one implementation method, a spring ball plunger type 10 special sleeve can be used to install and fix the C-type wire clamp body 6, such as... Figure 3 As shown, the special sleeve of spring ball plunger 10 consists of a sleeve body 11 and spring ball plungers 10 evenly distributed at its ends. The spring ball plungers 10 are evenly distributed at one end of the sleeve, and can use the spring force to stably press the flat washer onto the end face of the sleeve body 11, which is conducive to the stable installation of the flat washer, spring washer and nut into the special sleeve.

[0053] When installing the wire clamp, the nut, spring washer, and flat washer are placed sequentially into the special sleeve beforehand. Under the action of the spring ball plunger 10, the flat washer makes stable contact with the end face of the magnetic cover, forming an assembly of the nut, spring washer, flat washer, and special sleeve. This assembly is then installed as a whole onto the wire clamp bolt 5 and tightened with an electric wrench, effectively securing the nut, spring washer, and flat washer to the wire clamp as a single unit, preventing individual parts from falling off and improving work efficiency.

[0054] Example 2

[0055] This invention provides a working method for a complete set of C-type clamp installation tools for live-line work in power distribution networks, including:

[0056] The C-type wire clamp body 6 is clamped and fixed by the clamping mechanism;

[0057] The main line is locked and fixed to the inner upper surface of the C-type clamp body 6 using the main line locking mechanism 3;

[0058] The lead wire 7 is clamped and fixed to the lower inner surface of the C-type wire clamp body 6 using the lead wire clamping unit;

[0059] Place the C-type wire clamp wedge into the C-type wire clamp bolt 5;

[0060] Screw the spring ball plunger type 10 special sleeve, which has been fitted with nuts, spring washers and flat washers, into the C-type wire clamp bolt 5 and tighten it so that the C-type wire clamp body 6 crimps the lead wire 7 and the main wire.

[0061] Disconnect the clamp body fixing tool unit from the C-type clamp body 6 to complete the entire wiring process.

[0062] Specifically, the workflow of this complete tool suite is as follows:

[0063] Push the reset push rod 4-3 to move the locking tongue 4-4 to the reset position, as shown. Figure 1 Place the C-type clamp body 6 along with the bolt into the clamp fixing device 8, pull the pull pin 4-2, and the locking tongue 4-4 pops out to lock the C-type clamp body 6.

[0064] Hold the insulating handle 2-3 and rotate the insulating handle 2-3 counterclockwise to loosen the lead wire clamp 2-1 until the lead wire 7 can be inserted from the side into the position between the lead wire clamp 2-1 and the wire clamp. Pass the lead wire through the gap between the lead wire clamp 2-1 and the wire clamp, ensuring that the two clamps on both sides of the lead wire clamp 2-1 can clamp the lead wire.

[0065] Turn the insulating handle clockwise 2-3 until the lead wire is clamped;

[0066] Holding the insulated handle 2-3, pull the lead wire and clamp to the main wire 9 connection position, press the main wire 9 into the gap between the locking tongue and the C-shaped body, and lock the main wire 9 with the locking tongue. If the position of the main wire 9 needs to be adjusted, pull the first handle 3-2 to retract the locking tongue, so as to adjust the connection position. At this time, the C-shaped clamp body 6 and the clamp fixing device 8 are fixed in the connection position of the main wire 9, and a temporary passage is formed between the main wire 9 and the lead wire 7.

[0067] Place the C-type wire clamp wedge into the C-type wire clamp bolt 5;

[0068] The spring ball plunger type 10 special sleeve, which has been fitted with nuts, spring washers and flat washers, is screwed into the wire clamp bolt 5 with an electric wrench and tightened. At this point, the wire clamp has stably crimped the lead wire and the main wire 9.

[0069] Rotate the insulating handle 2-3 counterclockwise to loosen the lead wire clamp 2-1 to its maximum limit position;

[0070] Push the reset push rod 4-3 to reset the locking tongue 4-4;

[0071] Pull down the insulated handle 2-3 to detach the clamp body fixing tool unit from the C-type clamp body 6, completing the entire wiring process.

[0072] Precautions: This tool is suitable for live-line work at 10kV voltage level; this tool is suitable for operation inside the bucket of an insulated bucket truck; this tool is a special tool for live-line work and should be maintained, transported, and stored in strict accordance with the requirements for live-line work tools, avoiding throwing, squeezing, or forceful operation.

[0073] It improves operational safety. By using this tool instead of manually connecting live wires, it effectively prevents workers from getting caught in the circuit, avoiding the risk of electric shock; it also ensures a safe distance between workers and live parts, preventing workers from being injured by electric arcs.

[0074] It improves work efficiency. Using this tool to connect live leads simplifies the work process, avoids the need for workers to perform the task multiple times due to lack of skill, and reduces work time.

[0075] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
