Description

Technical Field

[0001] This invention relates to the field of overhead line technology, specifically to a wrapping device and method for insulation sheets of 35kV overhead transmission lines. Background Technology

[0002] Currently, most of my country's existing overhead power lines, such as 35kV transmission lines, are bare conductors. While these bare conductors in distribution networks had advantages such as cost savings and ease of construction in the past, their drawbacks have become increasingly apparent with the passage of time. For example, exposed conductors are prone to short circuits due to contact with trees, buildings, blown debris, birds, etc., or they may fall into water bodies, causing power outages or electric shocks.

[0003] Traditional solutions often involve replacing bare conductors with insulated cables to improve the insulation performance of the line. While this method can solve the line problem, it inevitably faces difficulties in actual operation, such as long construction periods and the need to shut down the power supply during operation. Therefore, a 35kV overhead transmission line insulation sheet wrapping device and wrapping method are proposed to solve the existing problems. Summary of the Invention

An upper pressure roller is rotatably arranged between the front and rear sides of the inner cavity of the U-shaped frame. A short rod is rotatably arranged on the front side of the mounting frame. The surfaces of the short rod and the lower pressure roller are fixedly connected to mutually meshing second gears. Pulleys are fixedly connected to the surfaces of the film coating transfer roller and the short rod at the bottom. A belt is drivingly connected between the two pulleys.

[0008] Preferably, the cleaning mechanism includes a semi-circular sleeve, which is fixedly mounted on the rear side of the semi-circular arc groove frame by a bracket. The interior of the semi-circular sleeve is provided with a brush layer, and a plurality of electric fans are equidistantly arranged around the inner wall of the semi-circular arc groove frame.

[0009] Preferably, an arc-shaped block is fixedly connected to the surface of the semi-circular arc groove frame on the right side, and a threaded pin is threadedly connected to the inside of the arc-shaped block. A slot for matching the threaded pin is opened on the rear side of the half gear on the right side.

[0010] Preferably, the top of the base is fixedly connected to a bottom frame via a bracket, and several bottom frames are equidistantly arranged. A sliding plate is slidably arranged on the top of the bottom frame via a sliding groove. A top frame is fixedly connected to the top of the sliding plate. The top frame and the bottom frame are fixedly connected by bolts. Three traveling wheels are rotatably connected between the inner cavities of the top frame and the bottom frame. A first drive motor is mounted on one side of the bottom frame via a bracket, and the output shaft of the first drive motor is fixedly connected to the end of the middle traveling wheel via a coupling.

[0011] Preferably, the top of the mounting frame is threadedly connected to a threaded adjusting rod via a threaded groove, and the bottom of the threaded adjusting rod is rotatably connected to the top of the U-shaped frame via a bearing. Limiting grooves are provided on the front and rear sides of the inner cavity of the mounting frame, and limiting blocks are slidably connected inside the limiting grooves. The two limiting blocks are fixedly connected to the front and rear sides of the U-shaped frame on opposite sides, respectively.

[0012] Preferably, the mounting frame is bolted to the front and rear sides with a support plate, and the support plate is rotatably provided with a multi-ribbed insert rod. The front and rear sides of the roll material reel are provided with multi-ribbed grooves that are matched with the multi-ribbed insert rod.

[0013] This invention also discloses a method for using a 35kV overhead transmission line insulation sheet wrapping device, specifically including the following steps: S1. Device suspension: Pull the top frame and bottom frame apart, then suspend the traveling wheels inside the top frame on the line, and then lock the bottom frame and top frame with bolts to make the traveling wheels in the upper and lower positions clamp the line. When the device moves, the traveling wheels can be driven by the first drive motor. S2. Line cleaning: After the walking wheels set at the upper and lower positions clamp the line, start the electric telescopic rod, which will drive the two semi-circular arc groove frames to merge and surround the outer surface of the line. The movement of the two semi-circular arc groove frames will synchronously drive the two semi-circular sleeves to cover the line. As the device moves, the brush layer in the semi-circular sleeves will clean the dust on the surface of the line. During cleaning, the electric fan will be started at the same time to blow away the dust that has been swept off. S3. Continuous wrapping of insulating sheet: The film on the surface of the insulating roll is peeled off, and the exposed adhesive side of the insulating roll is tilted and wrapped over the line surface. Then, the second drive motor is started. The second drive motor drives the first gear to mesh with the two merged half gears, causing the half gears to carry the mounting frame and the roll circumferentially. This causes the roll after the film is peeled off to be continuously wrapped obliquely over the line surface through circumferential movement. S4. Coating and winding: When the insulating sheet is released from the wrapping length by the circumferential moving tension, the upper and lower pressure rollers will rotate under the force. The rotation of the lower pressure roller synchronously drives the short rod to rotate through the meshing of two second gears. The short rod drives the coating transfer roller to rotate through the transmission of the pulley and belt. The rotation of the coating transfer roller continuously winds the separated coating into the inside of the placement frame.

[0014] Beneficial effects This invention provides a device and method for wrapping insulation sheets for 35kV overhead power transmission lines. Compared with existing technologies, it has the following advantages: (1) The 35kV overhead transmission line insulation sheet wrapping device and wrapping method, by setting a continuous wrapping mechanism, a film wrapping and winding mechanism and a cleaning mechanism on the base, enables the device to clean the line in advance through the coordinated cooperation of the continuous wrapping mechanism, the film wrapping and winding mechanism and the cleaning mechanism, and simultaneously wrap the insulation sheet continuously on the line surface during the cleaning process, thereby improving the insulation performance of the bare conductor, and simultaneously temporarily storing the film of the insulation sheet to avoid the film from drifting randomly and affecting the device's continuous wrapping of the insulation sheet on the line.

[0015] (2) The 35kV overhead transmission line insulation sheet wrapping device and wrapping method, by setting a support plate, multi-ribbed insert rod and multi-ribbed groove between the installation frame and the roll, makes the roll easy to disassemble and replace without affecting the rotation.

[0016] (3) The 35kV overhead transmission line insulation sheet wrapping device and wrapping method, by setting an arc block, threaded pin and slot between the right half gear and the semi-circular arc groove frame, makes the right half gear easy to anti-slip positioning during its idle period through the above-mentioned cooperation.

[0017] (4) The 35kV overhead power transmission line insulation sheet wrapping device and wrapping method, by setting a threaded adjustment rod in the internal thread of the mounting frame and rotating the bottom of the threaded adjustment rod to the top of the U-shaped frame, makes it easy to adjust the position of the U-shaped frame by adjusting the threaded adjustment rod, and makes it easy to adjust the distance between the upper pressure roller and the lower pressure roller.
