Description

Technical Field

[0001] This utility model belongs to the field of asphalt coating technology, and in particular relates to a cable asphalt coating device. Background Technology

[0002] In the field of cable manufacturing and protection, asphalt coating is a crucial step in ensuring cables possess excellent moisture-proof and corrosion-resistant properties. Traditional cable asphalt coating equipment typically includes an asphalt melting tank for heating and melting solid asphalt, and a series of mechanical components for uniformly coating the molten asphalt onto the cable surface. However, in practical applications, existing cable asphalt coating equipment has several technical problems and limitations, specifically: In existing technologies, incompletely melted solid asphalt can easily mix into areas of already melted asphalt, causing critical components such as drive wheels to become stuck, affecting normal equipment operation, and potentially leading to interruptions or uneven coating during the coating process. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a coating device that ensures the effectiveness of asphalt coating.

[0004] The objective of this utility model can be achieved through the following technical solution: a cable asphalt coating device, comprising:

[0005] An asphalt melting box, which is equipped with a heating element;

[0006] A baffle plate is fixedly installed inside the asphalt melting box, dividing the asphalt melting box into a melted zone and a melting zone. Solid asphalt in the melting zone is heated and melted before flowing to the melted zone.

[0007] An asphalt drive wheel is disposed within the melted zone and is rotatably connected to the asphalt melting box.

[0008] A conveyor plate is fixedly installed inside the asphalt melting tank, with its first end extending into the asphalt melting tank to receive asphalt transferred from the asphalt drive wheel. The second end of the conveyor plate is located outside the asphalt melting tank, and vertically, the first end of the conveyor plate is higher than the second end of the conveyor plate. The asphalt on the conveyor plate is coated on the cable.

[0009] In the above-mentioned cable asphalt coating device, the upper and lower ends of the baffle plate are divided into a material flow area and a material blocking area respectively along the vertical direction. The material blocking area includes a material blocking surface. The material flow area is provided with a plurality of through material flow holes connecting the melted area and the melting area. The heating part is located at the lower end of the asphalt melting box.

[0010] In the above-mentioned cable asphalt coating device, in the vertical direction, the length of the material flow zone is greater than the length of the material blocking zone.

[0011] In the above-mentioned cable asphalt coating device, the diameter of the material flow holes is the same in the vertical direction, and they are evenly distributed in an array.

[0012] In the above-mentioned cable asphalt coating device, a liquid level detection device is installed in the asphalt melting tank in the vertical direction.

[0013] In the above-mentioned cable asphalt coating device, the liquid level detection device includes a first liquid level sensor and a second liquid level sensor, with the first liquid level sensor located above the second liquid level sensor.

[0014] In the above-mentioned cable asphalt coating device, a cable outer diameter detection device is provided on the side of the asphalt melting box along the cable feeding and discharging direction, and the cable outer diameter detection device is electrically connected to the asphalt drive wheel.

[0015] In the above-mentioned cable asphalt coating device, the cable outer diameter detection device includes a first outer diameter detector and a second outer diameter detector located on both sides of the asphalt melting box.

[0016] In the above-mentioned cable asphalt coating device, the asphalt melting box is equipped with a drive motor that is connected to the asphalt drive wheel via a drive belt, and the drive belt is a V-belt.

[0017] In the above-mentioned cable asphalt coating device, the upper end of the asphalt melting box is provided with an opening that communicates with the melted area, and a cover plate is hinged to the asphalt melting box to cover the opening.

Detailed Implementation

[0024] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0025] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0026] like Figures 1-3 As shown, a cable asphalt coating device includes:

[0027] The asphalt melting box 100 is equipped with a heating element inside;

[0028] The baffle plate 101 is fixedly installed inside the asphalt melting box 100, dividing the asphalt melting box 100 into a melted zone 102 and a melting zone 103. The solid asphalt in the melting zone 103 flows to the melted zone 102 after being heated and melted.

[0029] An asphalt drive wheel 200 is disposed within the melted zone 102 and is rotatably connected to the asphalt melting box 100.

[0030] The conveyor plate 201 is fixedly installed inside the asphalt melting box 100. The first end of the conveyor plate 201 extends into the asphalt melting box 100 to receive the asphalt transferred from the asphalt drive wheel 200. The second end of the conveyor plate 201 is located outside the asphalt melting box 100. In the vertical direction, the first end of the conveyor plate 201 is higher than the second end of the conveyor plate 201. The asphalt on the conveyor plate 201 is coated on the cable 500.

[0031] In this embodiment, by setting a baffle plate 101 inside the asphalt melting tank 100, the asphalt melting tank 100 is divided into a melting zone 103 and a melted zone 102, effectively separating solid asphalt from molten asphalt. This structure can effectively prevent incompletely melted asphalt blocks from entering the subsequent coating area, thereby avoiding the problem of asphalt drive wheel 200 jamming due to foreign object blockage, and improving the stability and reliability of equipment operation.

[0032] It should be noted that, as Figure 4 As shown, the asphalt coating is the second layer extending from the outside to the inside in the 500 cross-section of the cable.

[0033] Furthermore, the asphalt drive wheel 200 is positioned within the melted zone 102 and rotatably connected to the asphalt melting box 100, enabling it to rotate smoothly within the melted asphalt and achieve uniform asphalt transfer. Simultaneously, in conjunction with the inclined conveyor plate 201, the asphalt flows naturally from high to low, improving the continuity and uniformity of the asphalt coating. The first end of the conveyor plate 201 extends into the asphalt melting box 100 to receive the asphalt transported by the asphalt drive wheel 200, while the second end extends outside the asphalt melting box 100, allowing the asphalt to fall onto the cable 500 under its own weight for coating.

[0034] Specifically, along the vertical direction, the upper and lower ends of the baffle plate 101 are divided into a material flow area and a material blocking area, respectively. The material blocking area includes a material blocking surface 104. The material flow area is provided with multiple through material flow holes 105 connecting the melted area 102 and the melting area 103. The heating part is located at the lower end of the asphalt melting box 100.

[0035] In this embodiment, the material blocking area is located below the partition plate, which can prevent unmelted solid asphalt from shifting to the melted area 102, preventing it from contacting and affecting the normal operation of key components such as the asphalt drive wheel 200. The material flow area is provided with multiple through-holes 105 to connect the melting area 103 and the melted area 102, allowing only molten liquid asphalt to slowly flow from the melting area 103 into the melted area 102 through the material flow holes 105, thereby effectively preventing unmelted block or granular asphalt from directly entering the subsequent coating area.

[0036] It should be noted that the melted area 102 and the melted area 103 are distributed along the horizontal direction.

[0037] Furthermore, in the vertical direction, the length of the material flow zone is greater than the length of the material blocking zone.

[0038] In this invention, the baffle plate 101 is vertically divided into an upper material flow zone and a lower material blocking zone, wherein the length of the material flow zone is greater than the length of the material blocking zone. This structural design has the following significant advantages: due to the longer length and larger area of ​​the material flow zone, the multiple material flow holes 105 provided thereon can provide a larger effective flow area, which is conducive to the smooth flow of molten asphalt from the melting zone 103 into the melted zone 102, thereby improving the efficiency and continuity of asphalt supply.

[0039] Furthermore, in the vertical direction, the flow orifices 105 have the same diameter and are evenly distributed in an array. The uniform diameter and array arrangement of the flow orifices 105 ensure that the flow velocity of liquid asphalt tends to be consistent at different heights, avoiding asphalt accumulation or flow interruption caused by uneven local flow velocities, thereby improving the stability of asphalt supply.

[0040] Further optimization involves installing a liquid level detection device inside the asphalt melting tank 100 in the vertical direction.

[0041] Specifically, the liquid level detection device includes a first liquid level sensor 300 and a second liquid level sensor 301, with the first liquid level sensor 300 located above the second liquid level sensor 301.

[0042] By installing a liquid level detection device inside the asphalt melting tank 100, real-time monitoring and control of the asphalt level in the melted zone 102 are achieved. Specifically, the liquid level detection device can accurately determine the quantity and status of the molten asphalt, thereby providing feedback signals to the automatic control system to ensure a stable and continuous asphalt supply and avoid problems such as overflow due to excessively high liquid levels or affecting the coating quality due to excessively low liquid levels.

[0043] Furthermore, this application employs a dual-level sensor arrangement, allowing for segmented detection of the asphalt level at different heights, thus establishing a high-low level linkage control mechanism. Specifically: the first level sensor 300 monitors the upper limit level; when the level reaches this height, the system automatically stops heating or suspends material supply to prevent asphalt overflow; the second level sensor 301 monitors the lower limit level; when the level falls below a set value, the system sends a replenishment or heating start signal to maintain normal coating operations.

[0044] Further preferably, along the infeed and discharge direction of the cable 500, a cable 500 outer diameter detection device is provided on the side of the asphalt melting box 100, and the cable 500 outer diameter detection device is electrically connected to the asphalt drive wheel 200.

[0045] Specifically, the cable 500 outer diameter detection device includes a first outer diameter detector 400 and a second outer diameter detector 401 located on both sides of the asphalt melting box 100.

[0046] In this embodiment, the cable 500 outer diameter detection device can dynamically acquire the actual outer diameter data of the cable 500, so that the rotation speed of the asphalt drive wheel 200 can be adjusted according to the difference in outer diameter of the cable 500 before and after asphalt coating, thereby adjusting the amount of asphalt coating to achieve the best coating effect.

[0047] Two outer diameter measuring instruments are located at the positions where the cable 500 enters and leaves the asphalt melting box 100, respectively. They can fully cover the changes in the state of the cable 500 before and after coating, which facilitates precise adjustment of coating process parameters and ensures the quality of the coating layer.

[0048] Further specifying, the asphalt melting tank 100 is equipped with a drive motor connected to the asphalt drive wheel 200 via a drive belt 202, which is a V-belt. Using a V-belt as the transmission medium allows for slippage on the pulley in the event of a sudden increase in load or the drive wheel being jammed by a foreign object. This prevents the direct transmission of excessive torque to the motor or transmission components, effectively preventing motor burnout or damage to mechanical parts, and providing excellent mechanical overload protection.

[0049] It should be noted that the first outer diameter measuring instrument 400 and the second outer diameter measuring instrument 401 are electrically connected to the drive motor to control the speed of the drive motor and thus adjust the speed of the asphalt drive wheel 200.

[0050] More preferably, the upper end of the asphalt melting box 100 is provided with an opening 106 that communicates with the melted area 102, and a cover plate 107 is hinged to the asphalt melting box 100 to cover the opening 106.

[0051] The design of the opening 106 allows operators to easily add solid asphalt raw materials to the asphalt melting tank 100 at any time, and to quickly check the melting status or perform necessary cleaning and maintenance. This not only improves the ease of operation of the equipment, but also simplifies the daily operation and maintenance process.

[0052] The hinged cover 107 effectively prevents burns caused by accidental splashing of molten asphalt, while also reducing the possibility of external impurities entering the asphalt melting tank 100, ensuring that the coating quality is not affected. Furthermore, closing the cover 107 during equipment operation reduces heat loss and improves energy efficiency.

[0053] It is worth mentioning that a through-hole exhaust port 108 is also provided above the asphalt melting box 100.
