Description

Technical Field

[0001] This invention relates to the field of insulating winding technology, specifically to an insulating winding for high-voltage busbars. Background Technology

[0002] In substation maintenance, wrapping the busbars of high-voltage equipment with clip-on insulating sleeves is a relatively effective insulation treatment. However, for the insulation treatment of gaps in the clip-on insulating sleeves and damaged areas of the insulating sleeves, the main method is still to wrap insulating tape.

[0003] For example, patent CN219321106U discloses a rotary insulating tape wrapper, including a handle and a wrapper. The right side of the handle's horizontal portion has a vertically penetrating receiving groove. A portion of the wrapper is located within this groove. The wrapper has a front-to-back penetrating circular groove. The handle contains a drive mechanism capable of rotating the wrapper. An annular groove is located within the circular groove's annular surface, and a clamping shaft is rotatably connected to the annular groove's arc surface. An insulating tape roll can be mounted on the clamping shaft. When insulating tape needs to be wrapped around a cable, the worker places the insulating tape roll on the clamping shaft, then passes the cable through the notch and positions it within the circular groove, attaching one end of the insulating tape roll to the cable. The wrapper then rotates.

[0004] In existing technologies such as those mentioned above, workers need to first attach one end of the tape to the cable before the tape wrapper can start automatically wrapping the tape. For equipment such as high-voltage busbars, this requires a power outage, otherwise the process of attaching the tape poses a significant safety hazard and can easily lead to electric shock accidents. In addition, for equipment such as high-voltage busbars located at high altitudes, it is difficult to attach the tape end to the object being wrapped using tools such as insulating rods on the ground. Summary of the Invention

[0005] The purpose of this invention is to provide a high-voltage busbar insulation winding device to solve the problem that the winding device in the prior art requires operators to stick the tape end to the winding object, which leads to safety hazards and inconvenience in operation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-voltage busbar insulation winding device, comprising a support with a C-shaped opening and a C-shaped rotating component capable of rotating around the C-shaped opening, a mounting plate fixedly mounted on the rotating component, a tape shaft for mounting tape rolls rotatably connected to the mounting plate, and a positioning and cutting mechanism for positioning and cutting tape on the support; the positioning and cutting mechanism comprises a fixed seat, a movable part, a top rod, and an end plate, the fixed seat being fixedly mounted on the support, the top rod for positioning tape being slidably connected to the fixed seat and driven by a linear drive component, the end plate being fixedly connected to one end of the top rod, a first blade mounted on the fixed seat, the movable part being connected to the fixed seat via an elastic telescopic rod, and a second blade mounted on the movable part; the positioning and cutting mechanism is provided with a locking assembly, which is assembled to lock the elastic telescopic rod in an extended state and release the lock when the end plate approaches the movable part.

[0007] Furthermore, the locking assembly includes a spring piece, with through holes respectively provided on the movable part and the end plate. One end of the spring piece is fixedly connected to the fixed base, and the other end passes through the through hole on the movable part and is provided with an inclined guide part. The spring piece has a bending structure. The side of the bending structure near the guide part is a blocking part that is basically parallel to the end plate, and the side away from the guide part is an inclined surface. When the end plate approaches the movable part, the through hole opening on the end plate slides and abuts against the guide part, so that the spring piece elastically deforms until the blocking part and the movable part disengage.

[0008] Furthermore, the spring is made of spring steel or POM engineering plastic.

[0009] Furthermore, both the first and second blades are arranged at an angle, forming an "eight" shape, and the inner side of the end plate is provided with blade grooves that are adapted to the first and second blades respectively.

[0010] Furthermore, the linear drive is an electric actuator or a linear motor.

[0011] Furthermore, the elastic telescopic rod is parallel to the top rod. The elastic telescopic rod includes a sleeve rod and an inner rod that are slidably connected to each other. The sleeve rod is fixedly connected to the fixed seat, and the outer end of the inner rod is fixedly connected to the movable part. A compression spring is provided between the sleeve rod and the inner rod. When the compression spring releases its elastic force, it drives the inner rod to extend out of the sleeve rod.

[0012] Furthermore, a guide shaft parallel to the tape axis is rotatably connected to the mounting plate, the guide shaft being used to guide the tape being released from the tape roll.

[0013] Furthermore, the rotating component is driven by a drive mechanism, which includes a drive motor mounted on a support and at least two spaced gears. The rotating component is provided with a gear ring, and the drive motor is used to drive the two gears to rotate. The two gears can respectively mesh with the gear ring.

[0014] Furthermore, the support is rotatably connected to a connecting part via a hinged support, and the connecting part is used to connect with the insulating operating rod.

[0015] Furthermore, the support is provided with multiple limiting wheels distributed in an arc shape, and the rotating component is rotatably connected to the support under the limiting position of each limiting wheel.

[0016] Compared with the prior art, the present invention provides a high-voltage busbar insulation winding device. By setting a positioning and cutting mechanism, the top rod can be connected to the tape head to achieve tape positioning before the winding operation. During the winding process, the tape head is cut by the first blade by fully retracting the top rod. At the end of the tape winding, the tape is cut by the second blade by partially retracting the top rod, which facilitates the removal of the winding device.

[0017] The positioning and cutting mechanism in this invention has three effects: firstly, the top rod can position the tape head, eliminating the need for operators to stick the tape head onto the busbar; secondly, it can cut the tape head, allowing the tape wrapped around the busbar to detach from the top rod; and thirdly, it cuts the tape when the tape wrapping on the busbar ends, detaching the tape from the busbar. Furthermore, the cut tape head on the tape roll can automatically stick to the top rod, thus facilitating the winding operation of the winder on other busbars. Attached Figure Description

[0031] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] Please see Figures 1-10 This invention provides a high-voltage busbar insulation winding device, comprising a support 1, a rotating component 2, and a cutting mechanism. The support 1 has a C-shaped opening, and the rotating component 2 is C-shaped and can rotate around the C-shaped opening. Both the C-shaped opening and the C-shaped rotating component 2 are designed to facilitate application onto the high-voltage busbar. The support 1 is rotatably connected to a connecting part 9 via a hinged support 8. The connecting part 9 serves as a support structure for an insulating operating rod, allowing operators to support the winding device for high-altitude operations from the ground. The hinged support 8 allows adjustment of the angle of the support 1, facilitating adjustments to the working posture of the support 1 according to the object to be wound. The support 1 is provided with multiple arc-shaped limiting wheels 10, and the rotating component 2 is rotatably connected to the support 1 under the limiting of each limiting wheel 10.

[0033] The rotating component 2 is driven by a drive mechanism 7, which includes a drive motor 71 mounted on a support 1 and at least two spaced gears 72. The rotating component 2 has a gear ring. The drive motor 71 drives the two gears 72 to rotate via a belt assembly 73. The two gears 72 can mesh with the gear ring respectively, and at least one gear 72 is meshed with the gear ring at any given time, thus ensuring that the rotating component 2 always has rotational driving force. The belt assembly 73 includes three pulleys and a belt. A pulley is coaxially fixedly connected to each of the two gears 72, and a pulley is coaxially fixedly connected to the shaft of the drive motor 71. The belt drive is sleeved on the three pulleys, so that the drive motor 71 can simultaneously drive the two gears 72 to rotate.

[0034] An arc-shaped mounting plate 3 is fixedly mounted on the rotating component 2, and the mounting plate 3 rotates together with the rotating component 2. A tape shaft 4 for mounting a tape roll is rotatably connected to the mounting plate 3, or the tape shaft 4 is fixedly connected to the mounting plate 3, and the tape roll is rotatably mounted on the tape shaft 4. A guide shaft 5 is also rotatably connected to the mounting plate 3, and the guide shaft 5 is used to guide the tape released from the tape roll. Both the tape shaft 4 and the guide shaft 5 are parallel to the axial direction of the rotating component 2.

[0035] The support 1 is equipped with a positioning and cutting mechanism 6 for positioning and cutting the tape. (See reference...) Figure 5 The positioning and cutting mechanism 6 includes a fixed base 61, a movable part 62, a push rod 63, and an end plate 64. The fixed base 61 is fixedly mounted on the support 1 by bolts. The push rod 63 is used to position the tape and is slidably connected to the fixed base 61 and driven by a linear drive 69, which is an electric push rod or a linear motor mounted on the support 1. The end plate 64 is fixedly connected to the end of the push rod 63 away from the linear drive 69, which can prevent the tape from detaching from the push rod 63. A first blade 65 is mounted on the fixed base 61. The movable part 62 is connected to the fixed base 61 by an elastic telescopic rod 67, and a second blade 66 is mounted on the movable part 62. Both the first blade 65 and the second blade 66 are arranged at an angle, forming a figure-eight shape. The inner side of the end plate 64 has grooves that are respectively adapted to the first blade 65 and the second blade 66. When the elastic telescopic rod 67 is extended, the second blade 66 is closer to the end plate 64 than the first blade 65.

[0036] The telescopic direction of the elastic telescopic rod 67 is parallel to the length direction of the top rod 63. Specifically, the elastic telescopic rod 67 includes a sleeve rod and an inner rod that are slidably connected to each other. The sleeve rod is fixedly connected to the fixed base 61, and the outer end of the inner rod is fixedly connected to the movable part 62. A compression spring is provided between the sleeve rod and the inner rod. When the compression spring releases its elastic force, it drives the inner rod to extend out of the sleeve rod.

[0037] The positioning and cutting mechanism 6 is also equipped with a locking assembly. The locking assembly is configured to lock the elastic telescopic rod 67 in the extended state and release the lock when the end plate 64 approaches the movable part 62. Specifically, the locking assembly includes a spring piece 68, which is made of spring steel or POM engineering plastic. The movable part 62 and the end plate 64 are respectively provided with through holes. One end of the spring piece 68 is fixedly connected to the fixed base 61, and the other end passes through the through hole on the movable part 62 and is provided with an inclined guide part 681. The spring piece 68 has a bending structure. The side of the bending structure near the guide part 681 is a blocking part 682 that is basically parallel to the end plate 64, and the side away from the guide part 681 is an inclined surface 683. When the end plate 64 approaches the movable part 62, the opening of the through hole on the end plate 64 slides and abuts against the guide part 681, so that the spring piece 68 elastically deforms until the blocking part 682 disengages from the movable part 62.

[0038] In use, the tape roll is fitted onto the tape shaft 4, and the tape end of the roll is wrapped around the guide shaft 5 and then adhered to the push rod 63. The push rod 63 is in a state where it is fully extended from the fixing seat 61. Figure 1 The winding device is lifted to the busbar using an insulated operating rod. The C-shaped opening of the support 1 coincides with the opening of the rotating component 2, thus placing the busbar at the center of the rotating component 2. Then, the drive mechanism 7 drives the rotating component 2 to rotate, which in turn drives the mounting plate 3 to rotate, causing the tape roll to release the tape and wrap it around the busbar. Before the mounting plate 3 reaches the positioning and cutting mechanism 6, the linear drive component 69 needs to drive the top rod 63 to partially retract into the fixed seat 61, thereby avoiding the tape passing through the positioning and cutting mechanism 6. Figure 3 At this point, there is still a gap between the first blade 65 and the end plate 64, and the tape head has not been cut.

[0039] After the tape has wrapped around the busbar several times, the linear drive 69 drives the push rod 63 to fully retract into the fixed seat 61. The first blade 65 embeds into the knife groove on the end plate 64, thereby cutting off the tape end between the busbar and the push rod 63, allowing the tape wrapped around the busbar to detach from the push rod 63. Then, the continuous rotation of the rotating component 2 causes the tape to continue wrapping around the busbar. When the tape wrapping on the busbar is about to be completed, the linear drive 69 drives the push rod 63 to fully extend out of the fixed seat 61. The push rod 63 blocks the movement path of the tape, intercepting it. After the mounting seat passes the positioning and cutting mechanism 6 for the last time, the tape is intercepted by the push rod 63. The tape should be wound and adhered to the push rod 63 as much as possible, ensuring that the tape is wound on the push rod 63 for more than 1 / 3 turn. Figure 4Then, the linear drive 69 drives the push rod 63 to retract part of the fixed seat 61, so that the second blade 66 is embedded in the knife groove on the end plate 64, cutting the tape between the busbar and the fixed seat, so that the tape is separated from the busbar, and the cut tape and the released tape on the tape roll can be automatically attached to the push rod 63, so that the winding machine can be removed from the current busbar and facilitate the subsequent winding operation of other busbars.

[0040] For the positioning and cutting mechanism 6, initially the movable part 62 is positioned between the fixed seat 61 and the end plate 64 under the elastic support of the elastic telescopic rod 67. The blocking part 682 of the spring piece 68 just abuts against the movable part 62, so the spring piece 68 has the function of preventing the movable part 62 from moving towards the fixed seat 61. Figures 6-7 As the push rod 63 retracts into the fixed seat 61 under the drive of the linear drive member 69, the push rod 63 first drives the end plate 64 to gradually approach the movable part 62, thereby enabling the second blade 66 to cut the tape. In the final stage before the end plate 64 abuts against the movable part 62, the opening of the through hole on the end plate 64 first slides and abuts against the guide part 681, causing the spring 68 to elastically deform. This causes the blocking part 682 of the spring 68 to disengage from the movable part 62, thus preventing the spring 68 from blocking the movable part 62. Figures 8-9 Therefore, the end plate 64 can drive the movable part 62 to move towards the fixed seat 61, thereby enabling the first blade 65 to cut the tape. During this process, the elastic telescopic rod 67 is further compressed, and the spring piece 68 passes through the through holes on the movable part 62 and the end plate 64 in sequence. Figure 10 During the process of the linear drive member 69 driving the push rod 63 to extend out of the fixed seat 61, the through hole opening of the end plate 64 and the through hole opening of the movable part 62 successively slide and abut against the inclined surface 683 of the bending structure of the spring piece 68, thereby enabling the bending structure to successively exit the through holes of the end plate 64 and the movable part 62, and thus resetting the positioning and cutting mechanism 6 to its original position. Figures 6-7 The initial state is shown.

[0041] By setting a guide shaft 5, since the tape roll can freely rotate and release the tape, there is an adhesive effect between the tape and the guide shaft 5 when the tape passes through the guide shaft 5. Therefore, the guide shaft 5 also has the function of tensioning the tape wound on the busbar, so that the tape is wound on the object under tension, tightly wrapped, and with good insulation effect. At the same time, the guide shaft 5 can also prevent the tape roll from releasing too much tape.

[0042] The foregoing description of certain exemplary embodiments of the present invention should not be construed as limiting the scope of protection of the claims. Those skilled in the art will recognize that the described embodiments can be modified in other ways without departing from the spirit and scope of the invention.
