Description

Technical Field

[0001] The present invention relates to the technical field of cable processing, and in particular to a conductor strand twisting device capable of twisting in one go and a use method thereof. Background Art

[0002] Since overhead high-voltage conductors are usually bare wires, there is usually no insulating protective layer on their surface. In order to improve the working performance of the conductors in harsh environments, a protective layer of paint is usually coated on the surface of the conductors to reduce the impact of the external environment on the conductors. However, when coating the already twisted conductors, special equipment is required to spray them, which increases the processing steps and additional costs of the conductors. In addition, existing high-voltage overhead conductors are usually formed by twisting, and the surface of the conductors is composed of many thin cores, and the cores are fitted together. Therefore, when the conventional method is used to coat the conductors with a protective layer, the protective layer of paint cannot penetrate between adjacent cores. When gaps are generated between the cores, the inside of the conductor is not protected by the paint. Therefore, the conventional coating method results in limited protection of the conductor by the paint. Summary of the invention

[0040] It also includes a pad 201 ; six pads 201 arranged in a ring are connected to the front side of the second turntable 8 by screws; each pad 201 is in contact with the adjacent wire core 4 .

[0041] It also includes a retaining ring 203; each spray tube 9 is installed with a retaining ring 203; each retaining ring 203 is initially located at the connection between the adjacent heating tube 202 and the spray tube 9; a through hole larger than the diameter of the wire core 4 is opened in the middle of the retaining ring 203.

[0042] It also includes a driving member 204; the retaining ring 203 is configured to be slidable in the spray tube 9; each heating tube 202 is fixedly connected to a driving member 204, and the driving member 204 is an electric push rod; the telescopic end of each driving member 204 is fixedly connected to the adjacent retaining ring 203.

[0043] Furthermore, in order to improve the spraying quality of the wire core 4 , each retaining ring 203 is provided with an inclined surface 20301 ; each retaining ring 203 is provided with a block portion 20302 .

[0044] In order to improve the protective effect of the protective layer on the wire, the twisting process of the wire is described in detail as follows:

[0045] First, the wire core 4 on the wire roller 3 is pulled out in turn, and the wire core 4 is passed through the guide frame 2001 to make the wire core 4 in a horizontal state, and then the wire core 4 passes through the first turntable 6, the second turntable 8, the spray tube 9 and the twisting ring 10 in turn, and then the motor on the base frame 1 is controlled to drive the fixed disk 2 to rotate on the fixed axis 1001, and the fixed disk 2 is driven to rotate clockwise based on the view from front to back, driving the fixed rod 2002 to rotate clockwise, thereby driving the first turntable 6 to rotate clockwise on the first fixed seat 5, and synchronously driving the second turntable 8 to rotate clockwise on the second fixed seat 7, thereby driving all the wire cores 4 to rotate clockwise, and the first rotating ring 5002 and the second rotating ring 7002 rotate clockwise synchronously. At the same time, the wire core 4 is moved to the front side by mechanical traction, and the six wire cores 4 are twisted through the twisting ring 10 to form a twisted conductor 4001, thereby realizing the twisting of the twisted conductor 4001. During the process, when the wire core 4 passes through the spray tube 9, the external feeding device is first controlled to convey the mist protective layer coating into the first air inlet 5001, so that the mist coating enters the first sealed cavity 5003, and then the mist coating enters the spray tube 9 through the pipeline, and the mist coating is sprayed from the jet hole of the spray tube 9 to the surface of the wire core 4. Since the jet holes of the spray tube 9 are arranged in a ring shape, the surface of each wire core 4 is covered with the protective layer material. Compared with the conventional method of coating the surface of the twisted conductor 4001 with a protective layer, the coating is covered in the process of twisting the twisted conductor 4001, and there is no need to use additional equipment to coat the twisted conductor 4001 with a protective layer, thereby reducing subsequent construction procedures and avoiding additional costs. In addition, the protective layer coating is fully covered on the wire core 4 through the spray tube 9, thereby improving the protection effect of the protective layer on the twisted conductor 4001.

[0046] Furthermore, when the wire core 4 passes through the pad 201, the protective layer of paint sprayed on the surface of the wire core 4 has not dried yet, and the connection strength between the protective layer of paint and the wire core 4 is small. When the wire core 4 passes through the second turntable 8 and moves toward the twisted ring 10, the wire core 4 contacts the second turntable 8, so the protective layer of paint on the surface of the wire core 4 is easily scraped off by the second turntable 8. For this reason, a hot air flow is transported to the second air inlet 7001 through an external hot air device, so that the hot air flow enters the second sealed cavity 7003, and then the hot air flow enters the heating tube 202 through the pipeline, so that the hot air flow is blown to the surface of the wire core 4 through the exhaust port of the heating tube 202, thereby accelerating the drying of the protective layer of paint on the surface of the wire core 4, so that the protective layer of paint is firmly attached to the wire core 4, and the protective layer of paint on the surface of the wire core 4 is prevented from being scraped off by the second turntable 8. It is explained here that when the second turntable 8 rotates, the second rotating ring 7002 rotates synchronously with the second turntable 8.

[0047] On this basis, when the wire core 4 passes through the second turntable 8 and moves toward the twisting ring 10, the wire core 4 is bent toward the middle of the twisting ring 10, so the wire core 4 is usually in contact with the edge of the second turntable 8. After long-term contact, it is easy to cause serious local wear at the edge of the second turntable 8, affecting the normal operation of the second turntable 8, and the wire core 4 is easy to fit on one side of the spray tube 9, affecting the spraying of paint on the wire core 4. For this reason, the wire core 4 is lifted up by the pad 201, and the pad 201 replaces the second turntable 8 to contact the wire core 4, thereby avoiding serious local wear of the second turntable 8. When the pad 201 is worn, only the pad 201 needs to be replaced separately, reducing the difficulty of maintenance of subsequent twisting equipment. In addition, the wire core 4 is lifted up by the pad 201, so that the wire core 4 is in the middle of the spray tube 9, and the jet hole of the spray tube 9 is relatively consistent with the position of the wire core 4, thereby improving the spraying uniformity of the protective coating.

[0048] When the spray tube 9 sprays the protective layer of paint on the wire core 4, as the spray tube 9 continues to spray out the mist paint, the mist paint in the spray tube 9 is easy to drift to the adjacent heating tube 202. At the same time, the temperature in the heating tube 202 is relatively high, so the drifted mist paint is easy to adhere to the surface of the wire core 4 again in the heating tube 202, which can easily cause the thickness of the protective layer of paint on the surface of the wire core 4 to be too thick, and then cause the protective layer of paint on the surface of the wire core 4 to crack, reducing the protective effect of the protective layer of paint. At the same time, the drifted mist paint is easy to adhere to the inner wall of the heating tube 202, so that a layer of protective layer of paint is attached to the inner wall of the heating tube 202, increasing the difficulty of cleaning the heating tube 202. For this reason, by setting the retaining ring 203 at the spray Between the coating tube 9 and the heating tube 202, most of the scattered mist coating is blocked from scattering into the heating tube 202, thereby reducing the content of mist coating in the heating tube 202, and further avoiding the protective layer coating thickness on the surface of the wire core 4 from being too thick, resulting in cracking of the protective layer coating, and reducing the difficulty of cleaning the heating tube 202. On this basis, due to the high content of mist coating in the spray tube 9, a large amount of dried protective layer coating is also attached to the inner wall of the spray tube 9, which is not convenient for cleaning. For this reason, the driving member 204 is controlled to drive the retaining ring 203 to move backward, so that the retaining ring 203 scrapes the inner wall of the spray tube 9 backward, thereby scraping off the protective layer coating attached to the inner wall of the spray tube 9, and cleaning the inner wall of the spray tube 9 is achieved.

[0049] Furthermore, when the retaining ring 203 scrapes the inner wall of the spray tube 9, impurities on the upper side of the spray tube 9 are scraped out and fall downward, and are easily attached to the wire core 4, thereby causing the paint on the local area of ​​the wire core 4 to be too thick, affecting the spraying quality. For this reason, the impurities on the upper side of the spray tube 9 are intercepted by the inclined surface 20301 to prevent the impurities from falling directly on the wire core 4, and the block portion 20302 is used to prevent the impurities on the inclined surface 20301 from falling on the wire core 4, thereby improving the spraying quality of the wire core 4.

[0050] Example 2

[0051] On the basis of Example 1, Figure 1 , Figure 5 and Figure 7-Figure 8As shown, the impurity cleaning system includes a conduit 301 and a cleaning ring 302; six conduits 301 arranged in an annular shape are installed on each first turntable 6; each conduit 301 is connected to the adjacent spray pipe 9, and each wire core 4 passes through the adjacent conduit 301; a cleaning ring 302 is connected to the rear side of each conduit 301 by screws; each cleaning ring 302 is provided with a scraper portion 30201, and a collecting groove 30202 is provided on the rear side of the scraper portion 30201; each scraper portion 30201 is in sliding contact with the adjacent wire core 4; a circular ring portion 30203 is provided on the rear side of each cleaning ring 302; the circular ring portion 3 An air suction hole is provided on 0203; a third air inlet 5004 is provided on the first fixed seat 5; the third air inlet 5004 is connected with an external air extraction device; a third swivel 5005 is rotatably connected to the rear side of the first fixed seat 5; a third sealed cavity 5006 is formed between the third swivel 5005 and the first fixed seat 5; the third sealed cavity 5006 is connected with the third air inlet 5004, and the third sealed cavity 5006 is connected with the air suction holes of all the annular parts 30203 through pipelines; a plurality of through grooves 30204 are provided on each cleaning ring 302; the collecting groove 30202 is connected with the spray pipe 9 through the through groove 30204.

[0052] The impurity cleaning system also includes a first gear 303 and a second gear 304; the first gear 303 is fixedly connected to the fixed shaft 1001; the first gear 303 is located in the first turntable 6; a second gear 304 is fixedly connected to the outer side of each conduit 301; all the second gears 304 are meshed with the first gear 303 for transmission; the annular portion 30203 is configured to be rotatable on the cleaning ring 302.

[0053] When dust and other impurities adhere to the surface of the wire core 4, the wire core 4's ability to absorb mist paint will be weakened, which may easily cause the protective layer of paint on the surface of the wire core 4 to fall off. For this reason, before the wire core 4 enters the spray pipe 9, the wire core 4 first passes through the cleaning ring 302 on the rear side of the guide tube 301; the dust on the surface of the wire core 4 is scraped off by the scraper portion 30201 on the cleaning ring 302, so as to prevent the dust from affecting the spraying quality, and then the scraped dust moves downward through the scraper portion 30201, and then falls into the collecting tank 30202. At the same time, the third air inlet 5004 is evacuated by controlling the external exhaust device, so that the air in the collecting tank 30202 enters the third sealed cavity 5006 through the pipeline, and then flows out from the third air inlet 5004 is discharged, and then the dust impurities in the collecting tank 30202 are discharged from the third air inlet 5004 by vacuum, and on this basis, the collecting tank 30202 is connected with the spray pipe 9 through the through groove 30204, so that the airflow in the spray pipe 9 flows from front to back, and the mist paint in the airflow spray pipe 9 is further blocked from diffusing toward the heating pipe 202 side. It is explained here that the suction force of the external vacuum equipment is relatively small at this time, and it can only guide part of the airflow in the spray pipe 9 to flow slowly backward, so it will not affect the spraying work of the mist paint on the wire core 4, and the dry paint scraped out by the retaining ring 203 is sucked out of the spray pipe 9 by vacuum, and then discharged from the third air inlet 5004, so as to realize the cleaning of the scraped paint.

[0054] On this basis, considering that the above design sets the suction force to be relatively small in order to avoid the influence of air extraction on the spraying work, and since the dry paint part scraped out by the retaining ring 203 is in the form of particles or flakes, the weight of the dry paint is relatively large, and it is difficult to suck out the dry paint in the spray tube 9 by relying on only a small airflow, for this reason, the retaining ring 203 is pushed to move backward into the conduit 301 by controlling the driving member 204, so that the dry paint scraped out by the retaining ring 203 is also pushed into the conduit 301, so that the scraped dry paint is close to the through groove 30204, so that the scraped dry paint is convenient for being sucked away and discharged by the airflow, and as the retaining ring 203 continues to move backward, until the block of the retaining ring 203 is reached. Part 20302 contacts with the scraper part 30201 of the cleaning ring 302, and the scraper part 30201 is engaged with the through hole of the baffle ring 203, so that the conduit 301 and the spray pipe 9 are separated by the baffle ring 203 and the cleaning ring 302. At this time, the baffle ring 203 and the conduit 301 are relatively sealed, so that it is convenient for the airflow to pass through the through groove 30204 to suck the scraped dry paint in the conduit 301 into the collecting groove 30202, and then be sucked away by the airflow. In addition, since the conduit 301 is separated from the spray pipe 9, the suction force of the external exhaust device is increased at this time, thereby increasing the airflow speed of the conduit 301, and further improving the suction effect of the dry paint.

[0055] Furthermore, when the collecting tank 30202 is evacuated, the air flow in the spray tube 9 flows from front to rear, and the hot air flow in the heating tube 202 flows backward synchronously, so that the hot air flow in the heating tube 202 enters the spray tube 9. At this time, the hot air flow is guided to blow toward the surface of the wire core 4 through the inclined surface 20301, and the surface of the wire core 4 is preheated, so that the temperature of the wire core 4 is increased before entering the heating tube 202, thereby accelerating the drying speed of the paint on the surface of the wire core 4 and improving the drying effect of the heating tube 202 on the wire core 4.

[0056] When the wire core 4 is a multi-strand wire, the strands of the wire core 4 are likely to become loose during the process of the wire core 4 being drawn out from the wire roller 3, thereby affecting the twisting tightness of the subsequent twisted conductor 4001. Therefore, based on the view from the front to the back, when the first turntable 6 rotates clockwise, all the catheters 301 and the second gear 304 are driven to rotate clockwise. At this time, the second gear 304 is meshed with the first gear 303 to make the second gear 304 rotate clockwise with the axis of the catheter 301 as the rotation center. , thereby driving the adjacent cleaning ring 302 to rotate clockwise, causing the cleaning ring 302 to rotate clockwise on the surface of the wire core 4, thereby applying a circumferential tightening force to the wire core 4, thereby making the loose strands of the wire core 4 tighter, and improving the twisting density of the subsequent twisted conductor 4001. It is explained here that when the first turntable 6 rotates, the third turntable 5005 rotates synchronously with the first turntable 6, and at the same time, the annular portion 30203 rotates on the adjacent cleaning ring 302, and the conduit 301 rotates on the adjacent spray pipe 9.

[0057] A method for using a conductor strand twisting device capable of twisting at one time, comprising the following working steps:

[0058] S1: Pull the wire, pull out the wire core 4 on the wire roller 3, and pass the wire core 4 through the guide frame 2001, the first turntable 6, the second turntable 8 and the twisting ring 10, and adjust the tension of the wire core 4;

[0059] S2: twisting, controlling the motor on the chassis 1 to drive the fixed disk 2 to rotate, driving the first rotating disk 6 and the second rotating disk 8 to rotate, thereby driving all the wire cores 4 to rotate, and twisting all the wire cores 4 through the twisting ring 10 to form a twisted conductor 4001;

[0060] S3: spraying, spraying the protective layer coating onto the surface of the wire core 4 through the jet hole of the spraying tube 9, so as to achieve full coverage of the protective layer coating, thereby improving the protective effect of the protective layer on the twisted conductor 4001;

[0061] S4: Heating, blowing hot air to the surface of the wire core 4 through the heating tube 202, accelerating the drying of the protective layer coating on the surface of the wire core 4, so that the protective layer coating is firmly attached to the wire core 4;

[0062] S5: Cleaning: scrape the dried paint on the inner wall of the spray tube 9 through the retaining ring 203, and discharge the scraped dried paint through the exhaust device to improve the spraying quality of the wire core 4.

Personnel familiar with the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope of the innovative features mentioned in the claims.
