Method for tensioning arrester core by using tensioning structure

Abstract

The tensioning structure for surge arrester core processing involves the following steps: Step 1: Place the fiberglass roll for surge arrester core processing onto an adjustable feeding tray; Step 2: Pass the fiberglass material through a conveying structure, forming a wave-shaped conveying channel via multiple feeding rollers and multiple tensioning rollers on an adjusting structure; Step 3: Adjust the position of the moving frame to control the feeding angle during winding; Step 4: Control the motor speed to control the winding speed of the fiberglass in the surge arrester core processing. This structure replaces the existing fiberglass tape feeding method with a uniformly tensioned and flexibly adjustable rotary feeding method. Combined with the rotation of the surge arrester's intermediate body, the opposite rotation, along with the tensioning, ensures a tight and uniform fiberglass tape winding process. This facilitates flexible loading, unloading, and replacement of the fiberglass tape material, provides stable clamping, and ensures smooth feeding. Simultaneously, processing efficiency is greatly improved, product quality is uniform and stable, and production efficiency is extremely high.

Description

[0001] This invention is a divisional application of "Tensioning structure for processing surge arrester core and method of use thereof" (application number: 202011562398X; application date: 2020-12-25). Technical Field

[0002] This invention relates to the field of electrical equipment technology, and in particular to a method for tensioning the surge arrester core using a processing tensioning structure. Background Technology

[0003] Surge arresters are electrical devices used to protect electrical equipment from high transient overvoltages caused by lightning strikes and to limit the duration and amplitude of follow current. They are sometimes also called overvoltage protectors or overvoltage limiters.

[0004] Surge arresters come in many types, including metal oxide surge arresters, line-type metal oxide surge arresters, gapless line-type metal oxide surge arresters, fully insulated composite-jacketed metal oxide surge arresters, and detachable surge arresters.

[0005] The main types of surge arresters include tubular surge arresters, valve surge arresters, and zinc oxide surge arresters. While the main working principles of each type differ, their essential function is the same: to protect communication cables and equipment from damage.

[0006] In the production and processing of surge arresters, multiple layers of epoxy resin-impregnated fiberglass tape need to be wound around an intermediate body composed of regularly arranged multiple resistor sheets. However, the traditional winding method does not have a good tensioning structure to control the tension of the fiberglass tape. The winding process relies heavily on manual operation for tensioning, resulting in uneven tension and high labor costs. In addition, uneven winding often occurs during the winding process, which not only affects the production quality of the surge arrester core but also leads to low efficiency. Summary of the Invention

[0007] The technical problem to be solved by this invention is to provide a method for tensioning the arrester core through a processing tensioning structure. This method replaces the existing fiberglass tape feeding method with a rotary feeding method that allows for uniform tension and flexible adjustment. Combined with the rotation of the arrester's intermediate body, the opposite rotation coordinates with the feeding and tensioning, resulting in a tight and uniform fiberglass tape winding process. This facilitates flexible loading, unloading, and replacement of the fiberglass tape material, ensures stable clamping, and provides smooth feeding. Simultaneously, processing efficiency is greatly improved, product quality is uniform and stable, and production efficiency is extremely high.

[0008] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a method for tensioning the arrester core by processing a tensioning structure for the arrester core, wherein the arrester core processing tensioning structure includes a turntable, and multiple tensioning units are evenly distributed around the center of the turntable. The turntable is set on a movable frame.

[0009] The tensioning unit includes a mounting rod connected to the turntable. One end of the mounting rod is provided with a conveying structure, and the conveying structure is provided with an adjustment structure that cooperates with it. The other end of the mounting rod is provided with an adjustable feeding tray.

[0010] The tensioning method is as follows:

[0011] Step 1: Place the fiberglass roll processed for the surge arrester core onto the adjustable feeding tray. Control the synchronous retraction of the chucks by rotating the adjusting rod. Then place the fiberglass roll onto the chucks and tighten the chucks with the elastic force of the elastic element to limit the position of the fiberglass roll, which is convenient for flexible replacement.

[0012] Step 2: The fiberglass material is conveyed through the conveying structure and forms a wave-shaped conveying channel through multiple feeding conveyor wheels and multiple tensioning conveyor wheels on the adjusting structure. The horizontal height difference between the feeding conveyor wheels and the tensioning conveyor wheels is controlled by the adjusting screw, thereby flexibly adjusting the tension.

[0013] Step 3: Adjust the position of the moving frame to control the feeding angle during winding processing. The electric push rod and the anti-slip support pad work together to limit the relative position of the turntable and the processing area. During the tightening process, the limit rod and the third limit groove will also work together to tighten, further ensuring that the turntable does not slip horizontally during operation.

[0014] Step 4: Control the motor speed to control the winding speed of the glass fiber in the surge arrester core. The winding process is continuously tensioned and the winding angle and tension can be flexibly adjusted.

[0015] Step 5: When wrapping the intermediate body of the surge arrester with fiberglass tape, the rotation direction of the intermediate body is opposite to the rotation direction of the turntable. The tension is maintained throughout the wrapping process, resulting in more uniform and faster wrapping.

[0016] In a preferred embodiment, the movable frame includes symmetrically arranged slide rails, with symmetrically arranged fixed plates between the slide rails. The fixed plates are equipped with pulleys that cooperate with the slide rails, and the fixed plates are equipped with mounting plates and support rods. The support rods are connected to a rotating shaft via connecting bearings. One end of the rotating shaft is connected to a turntable via a fixed block. The rotating shaft is equipped with a first gear, which is connected to a second gear located at the output end of a motor via a transmission chain. The motor is connected to the mounting plate via a fixed base.

[0017] In a preferred embodiment, the conveying structure includes a conveying frame, which is provided with a plurality of symmetrically arranged first limiting grooves, a plurality of mutually cooperating feeding conveying wheels, and a mounting frame, and the mounting frame is provided with an adjusting screw.

The bottom of the adjustment plate is provided with multiple symmetrically arranged connecting plates. The connecting plates are provided with a limiting block that is threaded with the first limiting groove and a tensioning conveyor wheel that is threaded with the feeding conveyor wheel.

[0019] In a preferred embodiment, the adjustable feeding tray includes a tray body rotatably connected to the mounting rod. The tray body is provided with multiple sliding grooves evenly distributed around the center of the tray body and an adjusting rotating rod connected to the center of the tray body. The sliding grooves are provided with a second limiting groove and a limiting slider that cooperates with the second limiting groove. The limiting slider is provided with a claw and an anti-slip texture.

[0020] In a preferred embodiment, the slide rail is provided with a third limiting groove, and the pulley is provided with a limiting rod that cooperates with the third limiting groove.

[0021] In a preferred embodiment, the fixing plate is provided with a plurality of symmetrically arranged mounting blocks, each mounting block is provided with an electric push rod, and the output end of the electric push rod is provided with an anti-slip support pad.

The support rod 31 is connected to a rotating shaft 33 via a connecting bearing 32. One end of the rotating shaft 33 is connected to a turntable 1 via a fixing block 34. A first gear 35 is mounted on the rotating shaft 33. The first gear 35, through a cooperating transmission chain 36, engages with a second gear 37 located at the output end of a motor 38 for transmission. The motor 38 is connected to the mounting plate 28 via a fixing seat 39. This significantly improves processing and production efficiency.

[0039] In a preferred embodiment, the conveying structure 5 includes a conveying frame 8, which is provided with a plurality of symmetrically arranged first limiting grooves 9, a plurality of mutually cooperating feeding conveying wheels 10 and a mounting frame 11, and the mounting frame 11 is provided with an adjusting screw 12.

[0040] The adjustment structure 6 includes an adjustment plate 13 that is threaded into the adjustment screw 12. The bottom of the adjustment plate 13 has multiple symmetrically arranged connecting plates 14. Each connecting plate 14 has a limiting block 15 that mates with the first limiting groove 9 and a tensioning conveyor wheel 16 that mates with the feeding conveyor wheel 10. This facilitates stable and flexible adjustment of the tension during the fiberglass tape feeding process, making it convenient and efficient.

[0041] In a preferred embodiment, the adjustable feeding tray 7 includes a tray body 17 rotatably connected to the mounting rod 4. The tray body 17 has multiple sliding grooves 18 evenly distributed around its center and an adjusting rod 43 connected to the center of the tray body 17. Each sliding groove 18 contains a second limiting groove 19 and a limiting slider 20 that cooperates with the second limiting groove 19. The limiting slider 20 has a claw 21 with anti-slip texture 22. One end of the limiting slider 20 is connected to the sliding groove 18 via an elastic element 23, and the other end is connected to the adjusting rod 43 via a traction rope 24. This facilitates the loading, unloading, and replacement of fiberglass tape materials, greatly improving efficiency while ensuring stable clamping, smooth feeding, and easy winding processing.

[0042] In a preferred embodiment, the slide rail 25 is provided with a third limiting groove 26, and the pulley 29 is provided with a limiting rod 30 that cooperates with the third limiting groove 26. This works in conjunction with the electric push rod 41 to further enhance the fixing effect.

[0044] Example 2:

[0045] like Figure 1-6 The method for tensioning the arrester core using the tensioning structure is as follows:

[0046] Step 1: Place the fiberglass roll processed for the surge arrester core onto the adjustable feeding tray 7. Control the synchronous retraction of the claw 21 by rotating the adjusting rod 43. Then place the fiberglass roll onto the claw 21. Then tighten the claw 21 with the elastic force of the elastic element 23 to limit the position of the fiberglass roll, which is convenient for flexible replacement.

[0047] Step 2: The fiberglass material is conveyed through the conveying structure 5 and through multiple feeding conveying wheels 10 and multiple tensioning conveying wheels 16 on the adjusting structure 6 to form a wave-shaped conveying channel. The horizontal height difference between the feeding conveying wheels 10 and the tensioning conveying wheels 16 is controlled by the adjusting screw 12, thereby realizing flexible adjustment of the tension.

[0048] Step 3: Adjust the position of the movable frame 3 to control the feeding angle during the winding process. The electric push rod 41 and the anti-slip support pad 42 work together to limit the relative position of the turntable 1 and the processing area. During the tightening process, the limit rod 30 and the third limit groove 26 will also work together to tighten, further ensuring that the turntable 1 will not slide horizontally during the operation.

[0049] Step 4: Control the rotation speed of motor 38, thereby controlling the winding speed of the glass fiber in the surge arrester core. The winding process is continuously tensioned and the winding angle and tension can be flexibly adjusted.

[0050] Step 5: When the intermediate body of the surge arrester is wrapped with fiberglass tape, the rotation direction of the intermediate body is opposite to the rotation direction of turntable 1. The tension is maintained continuously during the wrapping process, and the wrapping is more uniform and faster.

[0051] The beneficial effects of this invention are as follows: The existing fiberglass tape feeding method is changed to a rotary feeding method with uniform tension and flexible adjustment. In conjunction with the rotation of the intermediate body of the surge arrester, the fiberglass tape winding process is tight and uniform through rotation in opposite directions. It facilitates flexible loading, unloading and replacement of fiberglass tape materials, stable clamping and smooth feeding. At the same time, the processing and production efficiency is greatly improved, the product quality is uniform and stable, and the production efficiency is extremely high.
