[0018] The following will clearly and completely describe the technology of a high-voltage 110kV cable graphite coating device in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0019] Example 1 like Figure 1 and Figure 2As shown, a high-voltage 110kV cable graphite coating device includes a frame 10. The frame 10 is a prior art. Two symmetrical support components 20 are fixed to one side of the frame 10. The two support components 20 are respectively located at the two ends of the frame 10 and are used to support the cables passing through. A coating and drying component 60 is fixed to the middle of one side of the frame 10. The coating and drying component 60 is used to spray graphite liquid on the cables and dry the cables after spraying. Correction components 50 fixed to the frame 10 are installed on both sides of the coating and drying component 60. The two correction components 50 are respectively located on both sides of the coating and drying component 60 and are used to clamp the cables. A cleaning component 40 is installed on one side of one of the correction components 50. The cleaning component 40 is installed on the side where the cable enters and acts on the unpainted surface of the cable to clean the cable. A guide component 30 close to the cleaning component 40 is fixed on one side of the frame 10. The guide component 30 is used to support and position the cable.

[0020] Further, if Figure 3 As shown, the support component 20 includes a fixed frame 21 fixedly connected to the frame 10 through a mounting frame, the mounting frame is fixed to the frame 10, the fixing frame 21 is fixed to the mounting frame, and two groups of mutually perpendicular bidirectional screws 22 are rotatably mounted on the fixing frame 21, and the two groups of bidirectional screws 22 are located in different positions, one group of bidirectional screws 22 is in a horizontal state, and the other group is in a vertical state. The bidirectional screws 22 are rotatably mounted on the fixing frame 21, and the spiral part is located in the inner cavity of the fixing frame 21. One end of the two bidirectional screws 22 of the same group is fixed with a gear 1 23, and a group of bidirectional screws 22 consists of two parallel bidirectional screws 22. The end of the bidirectional screw 22 located on the outside of the fixing frame 21 is fixedly connected to the gear 1 23, and a rotating rod is fixed on one of the gears 1 23, which can control the rotation of the gear 1 23; Next, a gear 24 meshing with two gears 1 23 rotates on one side of the fixed frame 21. The two gears 1 23 and one gear 2 24 enable the two gears 1 23 to rotate in the same direction. The outer surfaces of the two bidirectional screws 22 in the same group are both threadedly connected to two mounting blocks 26 that are slidably connected to the side walls of the inner cavity of the fixed frame 21. The two mounting blocks 26 on the outer surface of a bidirectional screw 22 are symmetrical. A rotating roller 25 is rotatably installed between the two mounting blocks 26 on the same side. The rotating roller 25 is rotatably installed between the two corresponding mounting blocks 26 on the two bidirectional screws 22. Among them, by rotating the gear 1 23 in the vertical and horizontal directions, the two sets of bidirectional screws 22 are rotated, so that the two mounting blocks 26 connected to the bidirectional screws 22 move away from or close to each other, so that the four rotating rollers 25 can be centrally clamped to support the cable and place the cable in the corresponding position to prevent the cable from initial displacement.

[0021] Further, if Figure 4-6As shown, the guide component 30 includes a connecting plate 31 fixedly connected to the frame 10, and two symmetrical mounting plates are fixed on one side of the connecting plate 31, a motor 32 is fixed on one mounting plate, and a driving gear 321 is fixed on the output end of the motor 32, and an annular plate 34 is fixed on one side of the two mounting plates, and four annular array slide grooves 35 are opened on the two annular plates 34, and the inner cavities of the four slide grooves 35 are all slidably installed with limit assemblies 33, and the inner cavities of the two corresponding slide grooves 35 on the two annular plates 34 are jointly installed with a limit assembly 33, that is, the inner cavities of the four slide grooves 35 on the annular plates 34 are all installed with limit assemblies 33, and the limit assemblies 33 are used to clamp and guide the cables; Next, a rotating ring 36 is rotatably installed between the two annular plates 34. The rotating ring 36 is provided with two annular arrays of positioning grooves 1 37 and positioning grooves 2 38. The two positioning grooves 1 37 are in the vertical direction, corresponding to the two vertical slide grooves 35 on the annular plate 34, and the two positioning grooves 2 38 are in the horizontal direction, corresponding to the two horizontal slide grooves 35 on the annular plate 34. A half gear ring 39 is fixed to the outer surface of the rotating ring 36, which is meshed with the driving gear 321. The driving gear 321 causes the half gear ring 39 to rotate with the rotating ring 36, so that the positioning grooves 1 37 and positioning grooves 2 38 on the rotating ring 36 act on the limit assembly 33 in stages, causing the limit assembly 33 to move in stages. First, the two limit assemblies 33 in the vertical direction approach each other to solve the problem of cable sagging due to gravity and control the cable on the horizontal reference plane. Then, the two limit assemblies 33 in the horizontal direction approach each other to constrain the cable from deviating left and right. Among them, the first locking slot 37 and the second locking slot 38 can be divided into two sections, such as Figure 7 As shown, during the rotation of the rotating ring 36, the first stage of the two locking grooves 37 can move the limiting components 33 of the corresponding inner cavity of the slide groove 35, so that the two limiting components 33 are close to each other, clamping and supporting the cable in the vertical direction. At this time, the first stage of the two locking grooves 38 can keep the limiting components 33 of the inner cavity of the corresponding slide groove 35 stable, as shown in FIG. Figure 8 As shown, the second stage of the two first locking grooves 37 keeps the limiting components 33 of the corresponding inner cavity of the slide groove 35 stable. At this time, the second stage of the two second locking grooves 38 brings the limiting components 33 of the corresponding inner cavity of the slide groove 35 closer to each other, so that the two limiting components 33 in the horizontal direction are close to each other, restricting the left and right deviation of the cable; Step-by-step guidance can avoid over-constraint. If the four wheels contact the cable at the same time, a slight misalignment will generate internal stress, causing damage to the cable surface. In the first stage, the two vertical wheels mainly solve the problem of gravity sagging and control the cable on the horizontal reference plane. In the second stage, the two horizontal wheels begin to constrain the left and right deviations.

[0022] Further, if Figure 5As shown, the limiting assembly 33 includes a connecting rod 331 slidably installed in the inner cavity of the slide groove 35, the connecting rod 331 is located in the inner cavities of the two slide grooves 35 corresponding to the two annular plates 34, and U-shaped plates 332 are fixed at both ends of the connecting rod 331. The U-shaped plates 332 are tightly attached to the annular plates 34 on the same side, and guide wheels 333 are rotatably installed in the inner cavities of the two U-shaped plates 332. The guide wheels 333 are used to support and guide the cables.

[0023] Example 2 This embodiment further defines the cleaning component 40 and the deviation-correcting component 50 on the basis of the first embodiment, so as to prevent the problem of uneven pay-off or take-up.

[0024] Specifically, such as Figure 9 and Figure 10 As shown, the deviation-correcting component 50 includes a connecting plate 2 51 fixed to the frame 10. Two symmetrical support plates 52 are fixed to the connecting plate 2 51. A circular plate 1 53 is fixed to the side of each support plate 52 that is close to each other. A V-shaped guide wheel 1 54 is rotatably mounted between the two circular plates 1 53. The V-shaped guide wheel 1 54 is used to support the cable. A plurality of annular extrusion strips 1 55 are fixed to the outer surface of the V-shaped guide wheel 1 54. The extrusion strips 1 55 are made of silicone and have raised spots on the surface to increase friction. A connecting shaft 541 is fixed to one side of the V-shaped guide wheel 1 54 and passes through the support plate 52. The connecting shaft 541 passes through the support plate 52 on one side and is rotatably connected to the support plate 52 at the penetration point. Next, a cylinder 56 is fixed to one side of one of the support plates 52. The cylinder 56 is fixed to the support plate 52 on the side away from the connecting shaft 541. A connecting rod assembly 1 57 is fixed to the output end of the cylinder 56. The connecting rod assembly 1 57 includes a bottom plate, a fixed rod, a connecting spring and a top plate, wherein the connecting spring is fixed to the bottom plate. A connecting rod assembly 2 58 is fixed to the circular plate 1 53 on the same side as the connecting shaft 541 via a connecting frame. The connecting frame is fixed to the circular plate 1 53. The connecting rod assembly 2 58 also includes a bottom plate, a fixed rod, a connecting spring and a top plate, wherein the connecting spring is fixed to the bottom plate. An extrusion component 59 is installed on both the connecting rod assembly 1 57 and the connecting rod assembly 2 58. The extrusion component 59 is slidably installed on the fixed rods in the connecting rod assembly 1 57 and the connecting rod assembly 2 58. Further, if Figure 10As shown, the extrusion component 59 includes two straight plates 591, the fixing rods in the connecting rod assembly 1 57 and the connecting rod assembly 2 58 respectively penetrate the two straight plates 591, and the straight plates 591 are connected to the connecting springs in the connecting rod assembly 1 57 and the connecting rod assembly 2 58. The top plate is used to limit the movement position of the straight plates 591. A circular plate 2 592 is fixed on the side where the two straight plates 591 are close to each other. A V-shaped guide wheel 2 593 is rotatably installed between the two circular plates 592. The outer surface of the V-shaped guide wheel 2 593 is fixed with a plurality of annular arrays of extrusion strips. Second 594, extrusion bar second 594 has the same structure as extrusion bar one 55. The extrusion component 59 can be controlled to move up and down by the cylinder 56, connecting rod assembly one 57 and connecting rod assembly two 58, so that the V-shaped guide wheel one 54 and extrusion bar two 594 clamp the cable. When the cable is reeled in, the extrusion bar one 55 on the V-shaped guide wheel one 54 and the extrusion bar two 594 on the V-shaped guide wheel two 593 squeeze the cable. Under the action of friction, the cable moves, causing the V-shaped guide wheel two 593 and V-shaped guide wheel one 54 to rotate. The two deviation-correcting components 50 keep the cable in a taut state when passing through the inner cavity of the coating and drying component 60, so that the cable is evenly stressed and the cable is prevented from fluctuating, thereby making the cable coating uniform.

[0025] Further, if Figure 11 As shown, the cleaning component 40 includes two L-shaped frames 41 fixedly connected to the circular plate 53 via mounting rods. The L-shaped frames 41 are fixedly connected to the circular plate 53 on the same side via the mounting rods. A fixing ring 42 is fixed to the vertical parts of the two L-shaped frames 41. A mounting tube 44 is rotatably mounted in the inner cavity of the fixing ring 42. A plurality of spiral strips 43 in an annular array are fixed to the inner surface of the mounting tube 44. The spiral strips 43 are in close contact with the surface of the cable. When the mounting tube 44 rotates with the spiral strips 43, dust and impurities on the cable can be cleaned and discharged along the spiral direction of the spiral strips 43 without causing secondary pollution. Among them, a bevel gear ring 45 is fixed at one end of the mounting tube 44, and a bevel gear 46 meshing with the bevel gear ring 45 is rotatably installed on the horizontal part of one of the L-shaped frames 41. The bevel gear 46 and the connecting shaft 541 are connected by a pulley set. A pulley is fixed on the mounting shaft of the bevel gear 46, and a pulley is also fixed on the connecting shaft 541. Pulleys are wrapped around the two pulleys, so that the bevel gear 46 rotates with the connecting shaft 541, thereby rotating with the bevel gear ring 45, so that during the rotation of the V-shaped guide wheel 54, the bevel gear ring 45 rotates with the mounting tube 44, so that the spiral strip 43 in the inner cavity of the mounting tube 44 cleans the cable.

[0026] Further, if Figure 12As shown, the coating and drying part 60 includes a connecting frame 61 fixedly connected between the rack 10, one side of the connecting frame 61 is fixed with a coating and drying box 62, the inner cavity of the coating and drying box 62 is divided into a spraying cavity and a drying cavity, an adjustable spraying gun head is installed in the spraying cavity, which is used for spraying graphite liquid on the cable, a graphite liquid stirring barrel 63 is fixed on the connecting frame 61, the graphite liquid stirring barrel 63 is used for preparing graphite liquid, a hot gas generator 64 is fixed on one side of the coating and drying box 62, the hot gas generator 64 is used for conveying hot gas to the drying cavity of the inner cavity of the coating and drying box 62 to dry the sprayed cable.

[0027] It should be noted that the rack 10, the bidirectional screw 22, the motor one 32, the air cylinder 56, the coating and drying box 62, the graphite liquid stirring barrel 63 and the hot gas generator 64 in the present application are all prior art, and their installation methods and control methods are also conventional designs, which will not be described in detail.

[0028] The working principle of the present application: the mutual cooperation between the guide part 30 and the supporting part 20 can not only center and clamp the cable, but also guide it in stages. The two vertical wheels in the first stage mainly solve the problem of gravity sag, and control the cable on the horizontal reference surface. The two horizontal wheels in the second stage begin to constrain the left and right deviation, avoiding over-constraint of the cable, so as to solve the problem of cable deviation. In the process of use, the cable is pulled by the traction device, and the cable successively passes through the supporting part 20, the guide part 30, the cleaning part 40, the deviation rectifying part 50, the coating and drying part 60, the deviation rectifying part 50 and the supporting part 20. When the cable passes through the supporting part 20, the two groups of bidirectional screws 22 are simultaneously rotated by rotating the vertical gear one 23 and cooperating with the gear two 24, so that the two vertical rotating rollers 25 and the two horizontal rotating rollers 25 are close to each other, thereby clamping and supporting the cable. Then, the driving gear 321 cooperates with the half-toothed ring 39 to rotate the rotating ring 36 by controlling the motor one 32. In the process of rotating the rotating ring 36, as shown in Figure 7 As shown, the first stage of the two clamping grooves one 37 can move the connecting rod 331 in the inner cavity of the corresponding sliding groove 35, so that the two vertical limiting assemblies 33 are close to each other, thereby clamping and supporting the cable in the vertical direction. At this time, the first stage of the two clamping grooves two 38 keeps the connecting rod 331 in the inner cavity of the corresponding sliding groove 35 stable, as shown in Figure 8 As shown, the second stage of the two clamping grooves one 37 keeps the connecting rod 331 in the inner cavity of the corresponding sliding groove 35 stable. At this time, the second stage of the two clamping grooves two 38 makes the connecting rod 331 in the inner cavity of the corresponding sliding groove 35 close to each other, so that the two horizontal limiting assemblies 33 are close to each other, thereby constraining the left and right deviation of the cable. The device cooperates with the two correcting components 50 and the cleaning component 40 to keep the cables of the two correcting components 50 in a taut state when passing through the inner cavity of the coating and drying component 60, so that the cables are evenly stressed and the cables are prevented from fluctuating, thereby making the cable coating uniform. At the same time, the device can clean the cables that have not entered the coating and drying component 60, remove residual moisture, oil or dust on the cable surface, reduce the impact on wettability, and make the cable coating uneven, thereby avoiding affecting the shielding performance and electrical safety of the cables. Specifically, when the cable passes through the deviation-correcting component 50, the cylinder 56 controls the connecting rod assembly 1 57 to move the squeezing component 59, so that the cable is located on the outer surface of the V-shaped guide wheel 1 54. Then, the cylinder 56 lowers the squeezing component 59, so that the V-shaped guide wheel 2 593 and the V-shaped guide wheel 1 54 squeeze the cable. The cable located in the inner cavity of the coating and drying component 60 between the two deviation-correcting components 50 is kept taut by the squeezing force and is not affected by external forces. When the cable is pulled, the squeezing strip 2 594 on the V-shaped guide wheel 2 593 and the squeezing strip 1 55 on the V-shaped guide wheel 1 54 generate friction on the cable, so that the V-shaped guide wheel 1 54 rotates as the cable moves, thereby rotating the connecting shaft 541. Since the coupling shaft 541 and the mounting shaft of the bevel gear 46 are connected by a belt, the bevel gear 46 rotates with the bevel gear ring 45, thereby rotating the mounting tube 44. During the rotation of the mounting tube 44, the spiral strips 43 in the inner cavity of the mounting tube 44 clean the surface of the cable, and the cleaned impurities are discharged along the spiral direction of the spiral strips 43. When the cable passes through the inner cavity of the coating and drying component 60, the graphite liquid is first sprayed on the surface of the cable by the spray gun head in the spray chamber, and then enters the drying chamber for drying.

Any technician familiar with the technical field within the technical scope disclosed by the present invention, according to the technology of the present invention a high-voltage 110kv cable graphite coating device and its inventive concept, make equivalent replacements or changes, should be covered within the scope of protection of the present invention.
