[0008] A rotating assembly is rotatably mounted on the frame. The rotating assembly is used to engage with a wire stranding device. The rotating assembly is provided with a plurality of receiving channels that pass through the rotating assembly along its axial direction and are used to allow the wire to pass through the rotating assembly.

[0010] In one possible implementation, the plurality of receiving channels are evenly spaced around the rotation axis of the rotating assembly;

[0011] The rotating component has multiple flow guide holes on its peripheral wall, and the flow guide holes are connected to the receiving channel.

[0012] The coating assembly is used to spray the slurry from the periphery of the rotating assembly onto the rotating assembly, so that the slurry enters the receiving channel through the guide hole.

[0020] The reflux chamber is located below the rotating assembly and has an upward-opening reflux channel to collect slurry dripping from the rotating assembly.

[0021] In one possible implementation, the coating assembly further includes a return pipe and a second drive pump;

[0022] The return pipe connects the return trough to the interior of the slurry container;

[0023] The second drive pump is mounted on the return pipe and is used to drive the slurry in the return tank to flow into the slurry container.

[0024] In one possible implementation, at least one heating element is also included, wherein at least one of the coating chamber, the feed pipe, the return chamber, and the return pipe is provided with at least one heating element for heating the slurry.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0046] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0047] In related technologies, submarine cables include a core layer and an armor layer wrapped around the core layer. The armor layer is made of multiple stranded steel wires wrapped around the core layer. To ensure the corrosion resistance of the steel wires during use, asphalt is coated on the steel wires.

[0048] One method of coating asphalt on steel wire is to use a twisting device to twist the steel wire and wrap it around the core layer, and then pour asphalt slurry onto the whole formed by the steel wire and the core layer, thereby coating the surface of the steel wire with asphalt slurry.

[0049] However, when coating steel wires with asphalt using the above method, the contact surfaces between steel wires, or the side of the steel wire facing the core layer, are prone to not being coated with asphalt, resulting in uneven coating of asphalt slurry on the steel wires and poor anti-corrosion effect of the steel wires.

[0050] Therefore, this application provides a wire coating apparatus, including: a frame; a rotating assembly, which is rotatably mounted on the frame and is used to engage with a wire stranding device, the rotating assembly having a plurality of receiving channels that pass through the rotating assembly along its axial direction and are used to allow wires to pass through the rotating assembly; and a coating assembly, which sprays slurry into the receiving channels so that the slurry is coated onto the wire from the receiving channels. Therefore, before twisting and wrapping the steel wires onto the core layer, the steel wires can be threaded into the respective receiving channels so that the rotating component supports the rotation of each steel wire. The steel wires can also move relative to the receiving channels under the support of the rotating component. Then, they are twisted and wrapped onto the core layer. During this process, asphalt is sprayed into each receiving channel by the coating component. As the rotating component rotates, the asphalt entering the receiving channel can be coated onto the steel wire from multiple angles, making the asphalt coating on the steel wire more comprehensive and improving the coating effect. This solves the problem of uneven asphalt slurry coating on the steel wire in related technologies, which results in poor anti-corrosion effect of the steel wire. At the same time, the rotating component also has a better splitting effect on multiple steel wires, reducing the use of splitters when twisting and wrapping the steel wires onto the core layer and simplifying the installation steps of the splitters.

[0051] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0052] like Figure 1 As shown in the embodiment of this application, a wire coating apparatus includes:

[0053] 100 racks;

[0054] A rotating assembly 200 is rotatably mounted on a frame 100. The rotating assembly 200 is used to connect with a wire stranding device. The rotating assembly 200 is provided with multiple receiving channels 300. The receiving channels 300 pass through the rotating assembly 200 along the axial direction of the rotating assembly 200 and are used to correspondingly allow wires to pass through the rotating assembly 200.

[0055] Coating assembly 400 is used to spray slurry into receiving channel 300 so that the slurry is coated onto the wire from receiving channel 300.

[0056] It should be noted that the receiving channel 300 is used to accommodate the threaded wire, which can be selected according to actual needs, such as steel wire, cable, or other wires. The coating component 400 is used to spray the slurry to be coated into the receiving channel 300, where the slurry to be coated can be selected according to actual needs, such as asphalt, waterproof coating, or other coatings. In this embodiment, steel wire is used as an example of the thread, and asphalt is used as an example of the slurry to be coated.

[0057] In practice, the steel wire typically passes through a splitter and then is pulled and twisted by a stranding device to coat the core layer. The splitter and stranding device can be existing products, and this embodiment does not impose any limitations on them. Next, a wire coating device is installed between the splitter and the stranding device. Before the steel wire is stranded and coated onto the core layer, it is first threaded into each receiving channel 300, allowing the rotating assembly 200 to support the rotation of each wire, and enabling the wire to move relative to the receiving channel 300 under the support of the rotating assembly 200. In other words, each steel wire passes through the receiving channel 300 before being stranded and coated onto the core layer.

[0058] During this process, asphalt is sprayed into each receiving channel 300 through the coating component 400, so that the asphalt can be more comprehensively coated onto the steel wire from the receiving channel 300, thereby improving the coating effect of asphalt on the steel wire and solving the problem of uneven coating of asphalt slurry on the steel wire in related technologies, which results in poor anti-corrosion effect of the steel wire.

[0059] In some embodiments, since the rotating assembly 200 also has a better splitting effect on multiple wires, the use of a splitter can be reduced when the wires are stranded and covered with the core layer, thus simplifying the installation steps of the splitter.

[0060] It should be noted that the rotation speed of the rotating component 200 is matched with the twisting speed of the wire driven by the twisting device, which can reduce the possibility of mutual interference or entanglement of the wires during the traction process.

[0061] like Figure 1 As shown, in some embodiments, the rotating assembly 200 includes a transmission turntable 210 and a rotating support 220. The transmission turntable 210 is rotatably mounted on the frame 100, and the rotating support 220 is coaxially connected to the transmission turntable 210. The receiving channel 300 is formed on the rotating support 220.

[0062] In this embodiment, the rotation axis of the rotating assembly 200 is horizontal. Specifically, the rotating bracket 220 can be coaxially connected to the transmission turntable 210 by a rotating shaft, and the rotation axes of the transmission turntable 210, the rotating bracket 220, and the rotating shaft all extend horizontally. The two ends of the rotating shaft can be connected to the rotating bracket 220 and the transmission turntable 210 respectively by welding, screwing, or other means, and in this case, the rotating shaft passes through and is rotatably connected to the frame 100.

[0063] A drive assembly 500 is provided on the frame 100, which is used to drive the transmission turntable 210 to rotate. It can be understood that the drive assembly 500 drives the transmission turntable 210 to rotate, and then the transmission turntable 210 drives the rotating support 220 to rotate.

[0064] like Figure 1 and Figure 2 As shown, in this embodiment, multiple receiving channels 300 are evenly spaced around the rotation axis of the rotating assembly 200 on the rotating bracket 220. The receiving channels 300 penetrate the rotating bracket 220 along its axial direction, with both ends of the receiving channels 300 extending to opposite axial sides of the rotating bracket 220. Multiple guide holes 310 are provided on the peripheral wall of the rotating bracket 220 in the rotating assembly 200, and the guide holes 310 are correspondingly connected to the receiving channels 300.

[0065] The coating assembly 400 is used to spray slurry from the periphery of the rotating assembly 200 onto the rotating support 220 in the rotating assembly 200.

[0066] During implementation, the steel wires pass through the receiving channel 300 on the rotating bracket 220 and are then twisted and wrapped around the core layer. During this process, the drive assembly 500 drives the transmission turntable 210 to rotate, thereby causing the rotating bracket 220 to rotate and thus driving multiple steel wires to rotate around the axis of rotation of the rotating bracket 220. Simultaneously, the coating assembly 400 sprays asphalt onto the outer peripheral wall of the rotating bracket 220. As the rotating bracket 220 rotates, the asphalt enters the receiving channel 300 through the guide hole 310, allowing for a relatively comprehensive coating of the steel wire surface within the receiving channel 300.

[0067] In practice, multiple support holes 211 distributed around the rotation axis can be made on the transmission turntable 210. Each support hole 211 corresponds to each receiving channel 300, allowing the steel wire to pass through both the receiving channel 300 and the support hole 211 simultaneously. Thus, the transmission turntable 210 and the rotating bracket 220 can simultaneously support each steel wire, stabilizing the extension trajectory of the steel wire, improving the stability of the steel wire when passing through the receiving channel 300, and optimizing the coating effect of asphalt on the steel wire.

[0068] like Figure 1 As shown, in some embodiments, the drive assembly 500 includes a drive member and at least a pair of support guide wheels 510, the support guide wheels 510 being rotatably mounted on the frame 100, and the transmission turntable 210 being mounted on each support guide wheel 510.

[0069] The driving element is used to drive at least one support guide wheel 510 to rotate, so as to drive the transmission turntable 210 to rotate through the support guide wheel 510.

[0070] In this embodiment, the support guide wheels 510 can be configured as a pair, each support guide wheel 510 being rotatably connected to the frame 100 around a horizontal rotation axis, and the two support guide wheels 510 are spaced apart. The support guide wheels 510 can be rotatably connected to the frame 100 via a rotating shaft. The transmission turntable 210 is simultaneously mounted on both support guide wheels 510, enabling mutual transmission between the support guide wheels 510 and the transmission turntable 210.

[0071] The driving component can be a motor and there is no limitation on the model. The driving component can be connected to one of the support guide wheels 510 through gears, chains or other means, so that the driving component can drive one of the support guide wheels 510 to rotate, thereby driving the transmission turntable 210 and the rotating bracket 220 to rotate.

[0072] In other embodiments, multiple pairs of support guide wheels 510 may be provided, and the transmission turntable 210 may simultaneously abut against multiple support guide wheels 510. In addition, the driving member may also be connected to multiple support guide wheels 510 simultaneously to drive multiple support guide wheels 510 to rotate at the same time, thereby driving the transmission turntable 210 to rotate.

[0073] like Figure 1 As shown, in some embodiments, the coating assembly 400 includes:

[0074] The hopper 410 is disposed on the periphery of the rotating component 200. The hopper 410 has a material cavity 450 inside and is provided with a plurality of injection holes 411 facing the rotating component 200. The injection holes 411 are connected to the material cavity 450.

[0075] Slurry container 420, slurry container 420 is used to store slurry;

[0076] Feed pipe 430 connects the interior of slurry container 420 to material chamber 450;

[0077] The first drive pump is installed on the feed pipe 430 and is used to drive the slurry in the slurry container 420 to flow into the material chamber 450.

[0078] In this embodiment, the slurry container 420 can be a box structure or a tank structure; its specific structure is not limited, as long as it can hold asphalt or other slurries to be coated. The two ends of the feeding pipe 430 are respectively connected to the interior of the slurry container 420 and the material cavity 450 of the storage tank 410. A first drive pump is installed on the feeding pipe 430 to drive the slurry in the slurry container 420 to flow into the material cavity 450.

[0079] The chamber 410 is located on the periphery of the rotating support 220, and each spray hole 411 on the chamber 410 faces the periphery of the rotating support 220.

[0080] In practice, the end of the feed pipe 430 can be connected to the slurry container 420 or the silo 410 by bolting, welding, flange connection or other means. The first drive pump can be a pipeline pump, a centrifugal pump or other type, and there are no restrictions on this.

[0081] During operation, the asphalt in the slurry container 420 is pumped into the material chamber 450 by the first drive pump. The asphalt in the material chamber 450 can then be sprayed onto the peripheral wall of the rotating support 220 through the spray hole 411, and then enter the receiving channel 300 through the guide hole 310, and then be coated onto the steel wire.

[0082] like Figure 1 and Figure 3 As shown, the container 410 further includes a coating container 412 and a return container 413;

[0083] The coating chamber 412 is located above the rotating assembly 200, and the material chamber 450 and the spray hole 411 are disposed on the coating chamber 412;

[0084] The return chamber 413 is located below the rotating assembly 200 and has an upward-opening return channel to collect slurry dripping from the rotating assembly 200.

[0085] Specifically, the reflux chamber 413 is located directly below the rotating bracket 220, and the reflux chamber 413 has an upward-facing reflux groove, the opening of which corresponds to the rotating bracket 220.

[0086] The coating chamber 412 can be fixed to the upper end of the return chamber 413 by screwing, welding or other means, so that the return chamber 413 is equivalent to the base of the coating chamber 412. Secondly, the coating chamber 412 can be an arc-shaped structure, so that the extension trajectory of the coating chamber 412 is arranged around the rotating bracket 220, that is, the coating chamber 412 extends to the side and above the rotating bracket 220.

[0087] The material chamber 450 and the spray holes 411 are formed on the coating chamber 412. The spray holes 411 face the rotating support 220, and multiple spray holes 411 are arranged around the rotating support 220. Understandably, at this time, the two ends of the feed pipe 430 are respectively connected to the interior of the slurry container 420 and the material chamber 450 on the coating chamber 412.

[0088] During operation, the asphalt entering the material chamber 450 is sprayed onto the peripheral wall of the rotating support 220 through the spray hole 411, and then enters the receiving channel 300 through the guide hole 310, where it is coated onto the steel wire. Secondly, excess asphalt on the rotating support 220 drips down into the return trough in the return chamber 413 to collect and reuse the excess asphalt, reducing asphalt waste.

[0089] In other words, as the rotating support 220 rotates, each asphalt guide hole 310 receives asphalt sprayed from the injection holes 411 at different positions, ensuring that each steel wire is coated with asphalt 360 degrees without any blind spots. When each receiving channel 300 rotates to the bottom, excess asphalt drips into the return groove in the return chamber 413 through the corresponding guide hole 310 under the action of gravity acceleration.

[0090] like Figure 1 As shown, in some embodiments, the coating assembly 400 further includes a return pipe 440 and a second drive pump.

[0091] The return pipe 440 connects the return trough to the interior of the slurry container 420;

[0092] The second drive pump is installed on the return pipe 440 and is used to drive the slurry in the return tank to flow into the slurry container 420.

[0093] The end of the return pipe 440 can be connected to the slurry container 420 or the return chamber 413 by bolting, welding, flange connection, or other means. The second drive pump can be connected to the return pipe 440 by bolting, flange connection, welding, or other means. The second drive pump can be a pipeline pump, a centrifugal pump, or other type, and there are no restrictions on this.

[0094] Therefore, excess asphalt on the rotating support 220 drips down and is collected in the return tank in the return chamber 413. The asphalt collected in the return tank can then be sent back to the slurry container 420 by the second drive pump, which facilitates the recycling of asphalt.

[0095] like Figure 1 As shown, in some embodiments, the wire coating apparatus further includes a pressure member 600, which is connected to the material chamber 450 and is used to apply pressure to the material chamber 450.

[0096] It should be noted that the air outlet of the pressurizing component 600 can be connected to the material chamber 450 through a pipe. The two ends of the pipe can be connected to the coating chamber 412 and the pressurizing component 600 respectively by bolting, welding, flange connection or other means.

[0097] During operation, gas or liquid (such as slurry) can be introduced into the material chamber 450 through the pressurizing component 600 to increase the pressure inside the material chamber 450. This allows the asphalt inside the material chamber 450 to be sprayed out from the injection hole 411 more stably, optimizing the spraying effect of the asphalt onto the rotating support 220. The pressurizing component 600 can be an air compressor, air pump, or other pressurizing device, and there are no restrictions on its use.

[0098] like Figure 1As shown, in some embodiments, the wire coating apparatus further includes at least one heating element 700, which is provided on at least one of the coating chamber 412, the feed pipe 430, the return chamber 413 and the return pipe 440. The heating element 700 is used to heat the slurry.

[0099] The heating element 700 can be an electric heating rod, an electric heating plate, an electric heating belt, or other forms, and there are no restrictions on this.

[0100] For example, in this embodiment, a heating element 700 is provided on the coating chamber 412, and the heating element 700 is selected as an electric heating rod. Specifically, two electric heating rods are provided and are respectively installed at opposite ends of the material cavity 450 in the extending direction. This is so as to heat the asphalt in the material cavity 450 by the electric heating rods, thereby reducing the possibility of the asphalt solidifying in the material cavity 450.

[0101] Heating elements 700 are also provided on both the feed pipe 430 and the return pipe 440. These heating elements 700 can be electric heating belts. Specifically, the electric heating belts are wound around the feed pipe 430 or the return pipe 440 to heat the asphalt inside the feed pipe 430 or the return pipe 440, thereby reducing the possibility of the asphalt solidifying inside the feed pipe 430 or the return pipe 440.

[0102] A heating element 700 is also provided on the return chamber 413, which can be an electric heating plate. Specifically, the electric heating plate is located at the bottom of the return chamber 413 to heat the asphalt collected in the return tank, thereby reducing the possibility of the asphalt solidifying in the return chamber 413.

[0103] In other embodiments, the installation position of the heating element 700 can be reasonably set according to actual needs to ensure that the asphalt does not easily solidify during the entire coating process.

[0104] In some embodiments, the wire coating apparatus may further include a controller and a temperature sensing element, the temperature sensing element being electrically connected to the controller and used to detect the temperature of the slurry;

[0105] The controller is electrically connected to the heating element 700 and is configured to control the heating temperature of the heating element 700 based on the temperature signal from the temperature sensor.

[0106] In other words, the controller is electrically connected to both the temperature sensor and each heating element 700. The controller can be a PLC controller, and the temperature sensing element can be a temperature sensor; any existing product can be used, and there are no restrictions on the model.

[0107] For example, a temperature sensor can be placed inside the material chamber 450 to detect the temperature of the asphalt inside the material chamber 450 and send the temperature signal to the controller. Then, the controller can adjust the heating temperature of each heating element 700 according to the received temperature signal to optimize the heating effect on the asphalt and ensure that the asphalt is always in an optimal flow state.

[0108] Correspondingly, a pressure sensor can also be installed in the material chamber 450. The pressure sensor can also be electrically connected to the pressurizing component 600 via a controller. The pressure sensor can detect the pressure in the material chamber 450, and then the controller can adjust the pressure input into the material chamber 450 via the pressurizing component 600 to ensure that the asphalt is always in an optimal flow state.

[0109] In implementation, a high-frequency camera can also be added to the coating chamber 412, and this camera can be electrically connected to the drive unit in the drive assembly 500 via a controller. This allows the visual recognition technology of the high-frequency camera to detect the coating effect on the steel wire, and the drive unit to dynamically adjust the rotation speed of the rotating bracket 220, achieving an adaptive coating effect. Existing products can be used for the high-frequency camera and controller.

[0110] In some embodiments, a filter element may be added inside the return pipe 440. The filter element may be a filter screen, a filter layer or other structure, so as to filter the asphalt entering the slurry container 420 from the return tank, reduce impurities in the reused asphalt and ensure the quality of subsequent asphalt use.

[0111] In some embodiments, explosion-proof valves and emergency pressure relief devices (such as pressure relief valves) may also be installed on the feed pipe 430, return pipe 440, and coating bin 412 to reduce the risk of asphalt leakage or explosion under high temperature and pressure. Existing products may be selected for the explosion-proof valves and emergency pressure relief devices.

[0112] An odor evaporator can also be installed in the return trough of the return chamber 413. When the slurry container 420 is an open structure, an odor evaporator can also be installed at the corresponding opening. Existing products can be used for the odor evaporator. The odor evaporator can reduce asphalt volatilization pollution through condensation and adsorption.

[0113] In summary, the wire coating apparatus provided in this application, before stranding and coating the steel wire onto the core layer, first threads the steel wires into the corresponding receiving channels 300, so that the rotating component 200 supports the rotation of each steel wire, and the steel wires can move relative to the receiving channels 300 under the support of the rotating component 200. During this process, asphalt is sprayed into each receiving channel 300 by the coating component 400, so that the asphalt is more comprehensively coated onto the steel wire from within the receiving channels 300, improving the coating effect of asphalt on the steel wire and solving the problem of uneven asphalt slurry coating on the steel wire in related technologies, resulting in poor anti-corrosion effect of the steel wire. At the same time, the rotating component 200 also has a better splitting effect on multiple steel wires, reducing the use of splitters when stranding and coating the core layer of steel wires, and simplifying the installation steps of splitters.

[0114] Finally, it should be noted that other embodiments of the invention will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This invention is intended to cover any variations, uses, or adaptations of the invention that follow the general principles of the invention and include common knowledge or customary techniques in the art not disclosed herein, and is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope.
