Description

Technical Field

[0001] The present invention relates to the technical field of cable line installation and connection, in particular to a lighting pipeline quick connection and installation device. Background Art

[0002] In the field of high-voltage power transmission and lighting lines, aluminum wire has become an important material for construction engineering and industrial lighting power supply due to its light weight, low price and good conductivity. It is widely used in the laying of lines for distributing power from high-voltage transmission lines to lighting areas, as well as in places such as internal line connections in large lighting facilities.

[0003] When a lighting circuit fails and requires emergency repair, or when wiring needs to be extended during installation, the connection technology of aluminum wires is directly related to whether the lighting system can operate safely, stably and efficiently.

[0004] At present, aluminum wire connections are mostly made by manual joints or connectors.

[0005] However, when repairing lighting circuit faults, the manual connection method has the following disadvantages: due to the wide distribution of lighting circuits, fault point detection and repair often need to be carried out in a complex environment. Manual wiring one by one is extremely inefficient and cannot meet the needs of quickly restoring lighting.

[0006] In addition, after searching, a patent document with patent application number CN202211162310.4 and IPC main classification number H02G15 / 18 disclosed a cable connection structure, a cable connection method and a cable connector, which mainly include a crimping sleeve and a protective sleeve; a threaded compression sleeve is provided on the basis of the protective sleeve, and a first groove and a compression head are provided in the compression sleeve, so that when the compression sleeve is tightened, the compression head is pushed to compress the cable and push the cable together, so that the cable bulges, which is conducive to the contact between the resistance point formed by the cable bulge and the compression head when the cable is subjected to tensile force.

[0007] It can be seen that the following problems exist when the connector overlap method is used in the prior art:

[0008] First, during the emergency repair of lighting cable line failures, the connectors are subjected to the impact of high voltage, high current and frequent power on and off. The contact resistance of the cable conductors at the connection points will gradually increase, and heat will intensify, reducing the reliability of the connection and may even cause secondary failures, resulting in repeated interruptions of the lighting system.

[0009] In addition, the reliability of the connection part of the method of using a compression head to compress the cable is still poor when the cable pipeline is subjected to impact force or pulling force, especially the safety is poor when dealing with application conditions under load impact state.

[0010] Based on this, it can be found that it is necessary to design a lighting pipeline quick connection and installation device that improves the cable line installation and connection construction efficiency and line installation safety. Summary of the Invention

A graphite half-ring is slidably mounted inside each of the insulating half-cylinders, and both ends of the graphite half-ring are slidably fitted inside the corresponding first constraint groove via the protrusions thereon. When the two first constraint grooves are butted together, the two graphite half-rings are butted together and a welding cavity is formed inside them for inserting the aluminum wire to be connected. An electrode constraint tube is integrally formed on the middle outer wall of each insulating half-cylinder. The interior of each electrode constraint tube is used to cooperate with the installation of an external heating electrode. After installation, the external heating electrode extends into the interior of the insulating half-cylinder and is used to press against the circumferential outer wall of the corresponding graphite half-ring to achieve electrical connection.

[0017] When the two graphite half rings in a tight state heat the internal aluminum wire, the graphite half rings are rotated as needed by moving the teeth by external force, and uniform mixing of the aluminum liquid and semi-fluid in the molten state is achieved during the rotation process.

[0018] Based on any of the above technical solutions, further optimization is that: the exposed length of the aluminum wire at the butt joint is greater than the length of the graphite half ring.

The interior of the combined wrapping spiral fitting is provided with a wrapping cavity for the aluminum wire to pass through after docking, the outer diameter of the wrapping cavity is larger than the outer diameter of the aluminum wire, and an annular storage space is formed between the two heating half-cylinders and the outer wall of the combined wrapping spiral fitting, and the interior of the storage space is used to store insulating material in a high-temperature fluid state, and the combined wrapping spiral fitting connects the wrapping cavity with the storage space through various guide ports provided thereon, and the insulating material in a flowing state enters the wrapping cavity through the various guide ports and is wrapped on the outer wall of the repaired aluminum wire.

[0020] Based on any of the above technical solutions, further optimization is that: a feed pipe joint is fixedly installed on the top of the heating half-cylinder, and the end of each feed pipe joint extends to the outside of the corresponding opposing slide, and each feed pipe joint is connected to the high-pressure discharge port of an external small portable injection molding machine.

[0022] Based on any of the above technical solutions, further optimization is that: the heating half cylinder is heated by an external electrode, and the outside of the heating half cylinder is configured with heat insulation material as needed.

[0023] Based on any of the above technical solutions, further optimization is that: by using external force to move the combined wrapped spiral tube, it can be driven to move along the axial direction of the aluminum wire and wrap the insulating material on the outer wall of the aluminum wire during the movement. After the insulating material on the outer wall of the aluminum wire cools down, a new insulating layer is formed.

[0024] On the basis of any of the above technical solutions, further optimization is that: the combined wrapped spiral tube includes two detachable semicircular threaded tubes with docking and clamping arrangements, and the outer side wall of the combined wrapped spiral tube formed by docking the two semicircular threaded tubes is provided with an external thread that screws into the internal thread on the inner side wall of each heating half-cylinder, and a number of guide ports are arranged at intervals along the length direction on both sides of the docking position of the two semicircular threaded tubes, and the interior of the two semicircular threaded tubes forms the wrapped cavity.

[0025] Based on any of the above technical solutions, further optimization is that: the semicircular threaded tube is made of graphite material.

[0026] Based on any of the above technical solutions, further optimization is that: a material diverter is integrally formed at the end of each of the semicircular threaded tubes; when the combined wrapped spiral tube component quickly and passively realizes spiral rotation under the action of external force, the insulating material flowing out of each of the guide ports is coated on the outer wall of the aluminum wire under the scraping action of the inner wall of the combined wrapped spiral tube component.

[0027] It should be noted that power distribution and connection are special operations that require special work according to requirements. Operators must wear high-temperature resistant insulating gloves or protective gear when using the lighting pipeline quick connection installation device. They must wear high-temperature resistant insulating gloves or use tools to complete the action when moving the material dial or the teeth.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. The present invention uses a bidirectional screw transmission structure to achieve counter-movement between the first half-ring connector and the second split wire wrapper, enabling rapid switching between welding and wrapping processes, shortening the time required to connect a single aluminum wire, and improving the efficiency of connecting multiple aluminum wires through dual-station parallel operation.

[0030] 2. This invention utilizes the high thermal conductivity, high temperature resistance (melting point of approximately 3652°C), and self-lubricating properties of the graphite half-ring to uniformly melt the aluminum wire butt ends through surface contact heating. Rotating teeth drive the graphite half-ring to rotate, evenly distributing the molten aluminum liquid under the action of centrifugal force. This eliminates the porosity defects in traditional welding, forms a dense weld joint, and improves the connection strength and reliability.

[0031] 3. The second split wire wrapper of the present invention adopts a dynamic spin coating process. High-voltage insulating material (10-15MPa) enters the coating cavity through the guide port. The sudden change in cross-sectional area produces a turbulent effect, increasing the contact area with the aluminum wire surface. When the material disc rotates, the edge scrapes the liquid insulating material and exerts centrifugal force, forcing the insulating material to evenly adhere to the aluminum wire surface. At the same time, the heated half cylinder maintains a local high temperature to delay the initial setting time, ensuring uniform thickness of the insulation layer and high molding quality.

[0032] 4. The bidirectional lead screw in the shifting mechanism of the present invention has a self-locking feature. Rotating the handwheel can precisely position the first half-ring connector and the second split wire wrapper. The guiding effect of the first constraint groove ensures the precise docking of the aluminum wire welding and the insulation wrapping, forming a welding cavity and a wrapping cavity that match the outer diameter of the aluminum wire, ensuring positioning accuracy and avoiding deviations that affect the connection effect.

[0033] 5. This invention employs insulating materials on the exterior of both the insulating and heating half-cylinders and requires operators to wear high-temperature resistant insulating gloves or protective gear (with a dielectric strength of ≥25kV / mm and hand temperature controlled below 40°C) to reduce the risk of burns and electric shock. Wearing protective gear is a mandatory step and embedded in standardized processes to enhance operational compliance. The flame-retardant properties of the protective gear can slow the spread of fire in the event of an accidental fire, ensuring operational safety. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0048] The following embodiments of the technical solution of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only used as examples and are not intended to limit the scope of protection of the present invention. Figures 1-12 As shown in .

[0049] Example 1: A lighting pipeline quick connection and installation device includes two first half-ring connectors 1 and second split wire wrappers 2 arranged at intervals. A shift mechanism is provided between the first half-ring connector 1 and the second split wire wrapper 2. The bottom of the shift mechanism is fixedly provided, and shift slides 3 are respectively installed on the upper and lower parts of the shift mechanism. The two shift slides 3 are respectively connected to the corresponding first half-ring connector 1 and second split wire wrapper 2. The first half-ring connector 1 is used to constrain the connection of the aluminum wire to be connected, and the second split wire wrapper 2 is used to wrap the new insulation layer of the aluminum wire after the connection is completed.

[0050] The device's shifting mechanism adopts a bidirectional screw 5 transmission structure. When the handwheel 4 is rotated to drive the bidirectional screw 5 to rotate, the two shifting slides 3 will move toward or away from each other along the screw axis because the upper and lower external threads of the screw rotate in opposite directions.

[0051] When aluminum wire connection is required, the hand wheel 4 is rotated to cause the two pairs of sliding seats 3 to drive the first half-ring connector 1 to open and the second split wire wrapper 2 to open, and respectively expose the graphite half rings 8 of the first half-ring connector 1; after the connection is completed, the hand wheel 4 is rotated again to make the two semicircular threaded tubes 20 of the second split wire wrapper 2 close to the connection point to realize the process switching.

[0052] Specifically, the operator disconnects the power to the line to be repaired and simultaneously exposes a suitable length of the connecting end of each aluminum wire to be connected. The rotating handwheel 4 at the top of the shifting mechanism is controlled to rotate, thereby driving the first half-ring connector 1 and the second split wire wrapper 2 to open. After opening, the two graphite half-rings 8 of the first half-ring connector 1 are spaced apart from each other. The two connecting ends of the aluminum wire to be connected are then docked and placed within the lower graphite half-ring 8. The graphite half-rings 8 are heated by an external power supply and heating electrodes. After heating to a set temperature, the two graphite half-rings 8 are controlled to return to docking and the butted ends of the aluminum wire are covered by the welding chamber. Under the high-temperature heating state, the butted ends of the two aluminum wires begin to melt. The heating temperature is controlled to wait for 15-20 seconds before stopping heating and releasing the two graphite half-rings 8. The welding state of the aluminum wire connection points is then observed. If qualified, the entire device is rotated so that the second split wire wrapper 2 is facing the currently connected aluminum wire. The aluminum wire is wrapped around two separate semicircular threaded tubes 20. Each feed pipe connector is connected to the high-pressure outlet of an external, portable injection molding machine via a multi-way connection or piping. High-pressure pumping rapidly delivers the high-temperature fluid insulation material to the storage space 17. The insulation within storage space 17 flows rapidly through various guide ports 18 into the wrapping cavity 16. Rapid reciprocating rotation of the material dial 14 causes the high-temperature fluid insulation material flowing into the wrapping cavity 16 to wrap around the exposed outer wall of the aluminum wire. During the wrapping process, the heating half-cylinder 13 is heated as needed by electrodes to delay the initial setting of the insulation material, providing sufficient time for safe operation by the electrician. After the new insulation layer is wrapped around the outside of the aluminum wire, the supply of insulation material and the heating of the heating half-cylinder 13 are stopped, and the insulation layer on the surface of the aluminum wire is allowed to cool down and solidify. The two semicircular threaded tubes 20 are separated by controlling the relative separation of the heating half-cylinder 13. After separation, they can be quickly removed, thus completing the docking of the aluminum wire conductors of the current aluminum wire and the wrapping of the new insulation layer on the outside of the aluminum wire.

[0053] Heating and welding process of graphite half ring 8: Graphite half ring 8 is used as a heating element. It takes advantage of its high thermal conductivity and high temperature resistance (graphite melting point is about 3652℃) to generate Joule heat through the external heating electrode, and quickly transfer the heat to the aluminum wire butt end (aluminum melting point is 660℃).

[0054] When the two butted graphite half rings 8 form a welding cavity, their inner walls are in close contact with the aluminum wire, forming surface contact heating, ensuring that the butted ends of the aluminum wire are evenly heated to a molten state, and the bonding is completed within 15-20 seconds, and a welding connection is formed after cooling.

[0055] During the insulation wrapping process, high pressure (typically 10-15 MPa) supplied by a small, portable injection molding machine forces the insulation material into the reservoir 17 at high speed, as a liquid. As it enters the wrapping cavity 16 through the guide port 18, the sudden change in cross-sectional area creates turbulence, increasing the contact area with the aluminum wire surface. Driven by an external force, the material disc 14 rotates along with the semicircular threaded tube 20, scraping the liquid insulation material along its edge, forcing it to evenly adhere to the outer surface of the aluminum wire. Simultaneously, the heated half-barrel 13 (made of graphite and electrically heated) maintains a localized high temperature, keeping the insulation material liquid during the wrapping process and preventing premature solidification.

[0056] During the welding process, the self-lubricating property of the graphite half ring 8 (easy sliding between graphite layers) is utilized, and the graphite half ring 8 is rotated by the shifting teeth 12, so that the molten aluminum liquid is evenly distributed under the action of centrifugal force, eliminating the porosity defects in traditional welding.

[0057] In the coating process, the traditional static casting insulation is changed to dynamic spin coating insulation, which improves the quality of the insulation layer molding.

[0058] Based on any of the above technical solutions, further optimization is that: when the first half-ring connector 1 completes the connection repair of the current aluminum wire, the second split wire wrapper 2 continues to wrap the aluminum wire after the connection repair with a new insulation layer; when the second split wire wrapper 2 continues to wrap the aluminum wire after the connection repair with a new insulation layer, the first half-ring connector 1 continues to complete the connection repair of the next aluminum wire to be connected inside the same cable.

[0059] After the first half-ring connector 1 completes welding of the first aluminum wire (taking about 20-30 seconds), the shifting mechanism drives the second split wire wrapper 2 to open, and at the same time, the first half-ring connector 1 is placed in the position of the second aluminum wire to be connected in the cable, realizing double-station operation.

[0060] The second split wire wrapper 2 is positioned at the connection point of the first aluminum wire by rotating the handwheel 4 and is wrapped around the outer periphery of the aluminum wire, starting the insulation wrapping process (which takes about 30 seconds). At the same time, the first half-ring connector 1 performs the welding operation on the second aluminum wire, forming a parallel operation process.

[0061] The first half-ring connector 1 and the second split wire wrapper 2 can also be operated independently as needed.

[0062] On the basis of any of the above technical solutions, further optimization is that: the counter-movement mechanism includes a vertically arranged vertical frame 6, and a connecting seat 7 is fixedly connected to the bottom of the vertical frame 6. The connecting seat 7 is in a fixed state relative to the ground when in use. A vertically arranged bidirectional screw 5 is installed inside the vertical frame 6. The top and bottom of the bidirectional screw 5 respectively pass through the through holes at the corresponding positions of the vertical frame 6 through stepped shaft sections, and a rotating handwheel 4 is inserted into the prismatic hole at the top of the upper stepped shaft section. The external threads of the upper and bottom of the bidirectional screw 5 have opposite rotation directions, and the counter-movement slide 3 is screwed on the side walls of the external threads of each section. The rotating handwheel 4 can drive the bidirectional screw 5 to rotate on a fixed axis by human rotation. When the bidirectional screw 5 rotates, it drives the two counter-movement slides 3 to move closer to or away from each other.

[0063] Preparation for welding station: Rotate the handwheel 4 counterclockwise, and the bidirectional lead screw 5 drives the two pairs of sliding seats 3 to move back to the extreme position (spacing 150mm), so that the graphite half ring 8 of the first half ring connector 1 is fully exposed, which is convenient for placing the two ends of the aluminum wire to be connected.

[0064] Wrapping station switching: After the welding is completed, rotate the handwheel 4 clockwise, and the two pairs of sliding seats 3 move toward each other. When the second split wire wrapper 2 moves to 5 mm away from the aluminum wire connection point, it stops. The position is kept fixed by the self-locking characteristics of the bidirectional screw 5, and the insulation wrapping process is started.

[0065] Positioning and clamping the aluminum wires: Manually rotate handwheel 4, and the bidirectional lead screw 5 drives the upper opposing slide 3, which in turn moves the insulating half-cylinder 9 of the first half-ring connector 1 downward, opening the two graphite half-rings 8 (disconnecting them). Place the butt ends of the two aluminum wires to be connected in the grooves of the lower graphite half-ring 8. Rotate handwheel 4 again to close the two graphite half-rings 8. The first restraining groove 10 guides the two halves, achieving precise docking and forming a welding cavity with an inner diameter that matches the outer diameter of the aluminum wires (e.g., if the aluminum wire diameter is 10 mm, the welding cavity inner diameter is 10.2 mm).

[0066] Heating and welding of graphite half ring 8: The external heating electrode (such as silicon carbide electrode) is in close contact with the outer wall of graphite half ring 8 through the electrode restraint tube 11, and the high conductivity of graphite (resistivity 5×10⁻ 6 Ω・m) generates Joule heat. Graphite half-ring 8 rapidly heats to 800°C (higher than the melting point of aluminum, 660°C), melting the aluminum wire ends through surface contact heat transfer. After heating continues for 15-20 seconds, the power is cut off and graphite half-ring 8 is released, allowing the molten aluminum to cool and solidify, forming a metallic bond.

[0067] During the heating process, the teeth 12 at the outer end of the graphite half ring 8 are moved by external force to drive the graphite half ring 8 to rotate, so that the molten aluminum liquid is evenly distributed under the action of centrifugal force, eliminating pores and shrinkage defects and forming a dense weld joint.

[0068] After the welding is completed, the hand wheel 4 is rotated to drive the bidirectional screw 5, so that the first half-ring connector 1 moves upward with the upper opposing slide 3, and the second split wire wrapper 2 moves downward with the lower opposing slide 3, and the two separate to the middle position (the distance is about 75mm).

[0069] Adjust the position of the device so that the second split wire wrapper 2 is aligned with the welded aluminum wire connection point, rotate the handwheel 4 again to drive the second split wire wrapper 2 to move downward until the semicircular threaded tube 20 inside it completely covers the aluminum wire connection point (covering length 50mm).

[0070] Pumping and filling of insulating material: Connect the feed pipe joint 19 to an external small portable injection molding machine (pressure 10-15MPa), start the injection molding machine, and the high-temperature liquid insulating material (polyethylene, temperature 220℃) enters the storage space 17 at high speed through the guide port 18. The sudden change in cross-sectional area generates a turbulent effect, ensuring that the insulating material is evenly filled into the gap between the coating cavity 16 and the aluminum wire.

[0071] Dynamic spin coating: External force activates the disc 14 at the end of the semicircular threaded tube 20, causing it to rotate along the aluminum wire's axis. The edge of the disc 14 scrapes the liquid insulation, creating centrifugal force that forces it to adhere evenly to the wire's surface. Simultaneously, the heated half-tube 13 (made of graphite and heated to 200°C) maintains a localized high temperature, delaying the initial setting of the insulation (extending the operating time to up to 60 seconds), making it easier for the operator to adjust the coating thickness.

[0072] Stop the injection molding machine feeding, turn off the external heating power supply of the heating half cylinder 13, and wait 10-15 seconds for the insulation material to cool and solidify. Rotate the hand wheel 4 to drive the second split wire wrapper 2 to separate, remove the device, and a continuous and dense new insulation layer will form on the surface of the aluminum wire.

[0073] On the basis of any of the above technical solutions, further optimization is that: the first half-ring connector 1 includes two insulating half cylinders 9 symmetrically arranged from top to bottom, the two ends of the insulating half cylinder 9 are through-set, and the two ends of the insulating half cylinder 9 are respectively integrally formed with a first constraint groove 10, the middle of the outer wall of the insulating half cylinder 9 is respectively fixedly connected to the opposing slide 3, and a graphite half ring 8 is respectively installed in the interior of each of the insulating half cylinders 9 in a sliding fit, and both ends of the graphite half ring 8 are slidably fitted in the raised portion 801 thereon. Inside the corresponding first constraint groove rails 10, when the two first constraint groove rails 10 are butted, the two graphite half rings complete the butt connection and form a welding cavity inside thereof for the aluminum wire to be connected to be inserted. An electrode constraint tube 11 is integrally formed on the middle outer wall of each of the insulating half cylinders 9. The interior of each of the electrode constraint tubes 11 is used to cooperate with the installation of an external heating electrode. After installation, the external heating electrode extends to the interior of the insulating half cylinder 9 and is used to press against the circumferential outer wall of the corresponding graphite half ring 8 to achieve electrical connection.

[0074] Based on any of the above technical solutions, further optimization is that when the external heating electrode is energized, the graphite half ring 8 is heated and the two graphite half rings 8 are heated to complete the welding of the aluminum wire constrained therein and solidify the welding point of the aluminum wire after cooling.

[0075] On the basis of any of the above technical solutions, further optimization is that: both ends of each of the graphite half rings 8 extend out of the outer end of the heat-insulating half cylinder 9, and a shifting tooth 12 is fixedly installed on the outer end of each of the graphite half rings 8; in the process of heating the internal aluminum wire by the two graphite half rings 8 in a tightened state, the shifting teeth 12 are shifted by external force to drive the graphite half rings 8 to rotate as needed, and uniform mixing of the molten aluminum semi-fluid in the molten state is achieved during the rotation process.

[0076] The operator uses a wrench to hook the shifting tooth 12 and applies a tangential force to rotate the graphite half ring 8 around its axis. The rotation angle range is 0-360 degrees, and the speed can be controlled by the force application frequency.

[0077] On the basis of any of the above technical solutions, further optimization is that: the exposed length of the aluminum wire at the butt joint is greater than the length of the graphite half ring 8 .

[0078] When the two graphite half rings 8 are butted together to form a welding cavity, the middle 25 mm of the exposed part of the aluminum wire is directly wrapped and heated by the graphite half ring 8, and 2.5 mm at each end is in the through area of ​​the insulating half cylinder 9 (not covered by graphite), forming a temperature gradient distribution of heating in the middle and heat dissipation at both ends.

[0079] On the basis of any of the above technical solutions, further optimization is that: the second split wire wrapper 2 includes two heating half cylinders 13 symmetrically arranged from top to bottom, the two ends of the heating half cylinder 13 are through-set, the middle of the outer wall of the heating half cylinder 13 is respectively fixedly connected to the opposing slide 3, and internal threads are respectively provided on the inner side walls of the two ends of the heating half cylinder 13, and a combined wrapped spiral pipe 15 is screwed in the internal thread cavity formed by the two heating half cylinders 13, and the interior of the combined wrapped spiral pipe 15 is provided with a connection for docking. The aluminum wire passes through the wrapping cavity 16, and the outer diameter of the wrapping cavity 16 is larger than the outer diameter of the aluminum wire. An annular storage space 17 is formed between the two heating half-cylinders 13 and the outer side wall of the combined wrapping spiral member 15. The storage space 17 is used to store high-temperature fluid-state insulating material. The combined wrapping spiral member 15 connects the wrapping cavity 16 with the storage space 17 through various guide ports 18 provided thereon. The insulating material in a flowing state enters the wrapping cavity 16 through the guide ports 18 and is wrapped on the outer side wall of the repaired aluminum wire.

[0080] The two heating half cylinders 13 (made of graphite) are fixedly connected to the opposing slide 3 through their outer walls and are arranged symmetrically in the vertical direction. The internal threads of the inner walls of the half cylinders are screwed together with the external threads of the combined sheathed spiral tube 15 to form a spiral transmission pair.

[0081] The combined wrapping spiral tube 15 is composed of two detachable semicircular threaded tubes 20 (graphite) joined together to form a wrapping cavity 16 (2mm larger in diameter than the aluminum wire; for example, if the aluminum wire diameter is 10mm, the wrapping cavity 16 has a diameter of 12mm). An annular material storage space 17 is formed between the outer wall of the combined wrapping spiral tube 15 and the inner wall of the heating half-cylinder 13. This storage space 17 communicates with the wrapping cavity 16 through evenly distributed guide ports 18.

[0082] Motion transmission process: External force drives the material dial 14 at the end of the semicircular threaded tube 20, driving the combined wrapped spiral tube to rotate clockwise along the internal thread of the heating half-cylinder 13. Due to the axial component of the thread transmission, the combined wrapped spiral tube moves downward along the axial direction of the aluminum wire. At the same time, the high-temperature insulating material (such as polyethylene, temperature 220°C) in the storage space 17 is sprayed into the wrapping cavity 16 through the guide port 18 under high pressure, forming an insulating layer of uniform thickness.

[0083] On the basis of any of the above technical solutions, further optimization is that: a feed pipe joint 19 is fixedly installed on the top of the heating half cylinder 13, and the end of each feed pipe joint 19 extends to the outside of the corresponding opposing slide 3, and each feed pipe joint 19 is connected to the high-pressure discharge port of an external small portable injection molding machine.

[0084] The feed pipe connector 19 is made of high-temperature-resistant stainless steel (316L), with an inner diameter of 6mm and an outer diameter of 10mm. It is screwed into the center of the top of the heating half-cylinder 13. A guide cone is machined inside the connector to guide the insulating material flow (flow rate of 1m / s) output by the injection molding machine into the storage space 17, reducing flow resistance.

[0085] The end of the feed pipe connector 19 extends about 20 mm outside the opposing slide 3 and is quickly connected to the discharge port of a small portable injection molding machine (displacement 50 cm³ / min) through a high-pressure hose (temperature resistance 250°C, pressure resistance 20 MPa) (using a ferrule-type connector, sealing pressure ≥ 15 MPa).

[0086] When the injection molding machine is started, the insulating material enters the annular storage space 17 between the heating half cylinder 13 and the combined wrapping spiral tube 15 through the feed pipe joint 19 under the action of the piston thrust (pressure 10-15MPa), forming a stable high-pressure fluid transmission channel.

[0087] On the basis of any of the above technical solutions, further optimization is that: the heating half cylinder 13 is made of graphite material.

[0088] On the basis of any of the above technical solutions, further optimization is that: the heating half cylinder 13 is heated by an external electrode, and the exterior of the heating half cylinder 13 is provided with heat-insulating material as needed.

[0089] By changing the input voltage through an external voltage regulator (adjustable from 0 to 24V), the heating power can be precisely controlled (accuracy ±5%), thereby adjusting the temperature of the heating half cylinder 13 (control accuracy ±5℃).

[0090] When using polyethylene insulation material, heat it to 220℃; when using silicone rubber insulation material, heat it to 180℃ to meet the process temperature requirements of different materials.

[0091] Based on any of the above technical solutions, further optimization is that: by using external force to move the combined wrapping spiral tube 15, it can be driven to move along the axial direction of the aluminum wire and wrap the insulating material on the outer wall of the aluminum wire during the movement. After the insulating material on the outer wall of the aluminum wire cools down, a new insulating layer is formed.

[0092] Example 2: Compared with Example 1, this example is different in that it also includes the following technical features:

[0093] On the basis of any of the above technical solutions, further optimization is that: the combined wrapped spiral tube 15 includes two detachable semicircular threaded tubes 20 that are connected and clamped together, and an external thread that is screwed together with the internal thread on the inner wall of each heating half-cylinder 13 is provided on the outer wall of the combined wrapped spiral tube 15 formed by connecting the two semicircular threaded tubes 20, and a number of guide ports 18 are provided at intervals along the length direction on both sides of the connecting part of the two semicircular threaded tubes 20, and the interior of the two semicircular threaded tubes 20 forms the wrapped cavity 16.

[0094] Two semicircular threaded tubes 20 (made of graphite) are butted against the concave holes through the clamping bosses at the ends to form a complete cylindrical combined wrapped spiral tube member 15 .

[0095] The external thread on the outer wall of the combined sheathing spiral member 15 is screwed into the internal thread on the inner wall of the heating half-cylinder 13. When an external force drives the combined sheathing spiral member 15 to rotate, the combined sheathing spiral member 15 moves axially along the aluminum wire due to the action of the thread lead, and at the same time drives the insulating material to flow spirally along the inner wall of the combined sheathing spiral member 15; the guide port 18 cooperates with the rotational movement to allow the insulating material to enter the sheathing cavity 16 in a tangential direction, forming a rotating flow field.

[0096] On the basis of any of the above technical solutions, further optimization is that: the semicircular threaded tube 20 is made of graphite material.

[0097] On the basis of any of the above technical solutions, further optimization is that: a material diverter disk 14 is integrally formed at the end of each of the semicircular threaded tubes 20; when the combined wrapped spiral tube 15 quickly and passively realizes spiral rotation under the action of external force, the insulating material flowing out of the inside of each of the guide ports 18 is coated on the outer wall of the aluminum wire under the scraping action of the inner wall of the combined wrapped spiral tube 15.

[0098] It should be noted that power distribution and connection are special operations that require special operations according to requirements. Operators must wear high-temperature resistant insulating gloves or protective gear when using the lighting pipeline quick connection installation device. They must wear high-temperature resistant insulating gloves or use tools to complete the action when moving the material disc 14 and the shifting tooth 12.

[0099] During the operation, personnel safety is guaranteed:

[0100] Reduced risk of burns: After wearing high-temperature resistant gloves, the surface temperature of the hand skin can be controlled below 40°C, which meets the thermal protection requirements of GB24540-2009 "Protective clothing for acid and alkali chemicals".

[0101] Elimination of electric shock risk: The dielectric strength of the insulating protective gear is ≥25kV / mm, which can withstand transient overvoltages above 10kV and meet the insulation safety level of power distribution operations.

[0102] Improved operational standardization:

[0103] Embedding standardized processes: Wearing protective gear is a necessary step in the operation, and personnel behavior is strictly regulated to avoid safety accidents caused by empiricism or luck (according to statistics, the accident rate for not wearing protective gear in a standardized manner is more than 5 times that of standardized operation).

[0104] Optimized emergency response: The protective gear material is flame-retardant (vertical burning damage length ≤ 100mm). If an accidental splash fire occurs, it can delay the spread of the fire and buy time for emergency treatment (delay time ≥ 30 seconds).
