Abstract
Description
Technical Field
[0001] The invention relates to the field of electric power maintenance equipment, and in particular to a support porcelain bottle replacement device for a dry-type air-core reactor. Background Art
[0002] In the daily maintenance of dry-type air-core reactors, aging and damage of the support porcelain bottles are common problems. In the prior art, the replacement of support porcelain bottles usually relies on large-scale mechanical equipment, which has the following problems:
[0003] Reliance on large mechanical equipment: Traditional replacement methods usually require the use of cranes or aerial work vehicles. Although such equipment can complete the hoisting and positioning of the reactor coil, due to the large operating space of cranes and aerial work vehicles, this method is difficult to implement in some substations with small sites or dense equipment. In addition, the rental, transportation and operation costs of mechanical equipment are high, which significantly increases the construction cost.
[0004] Long construction time: The traditional pillar porcelain bottle replacement solution usually requires the removal of the auxiliary structures of the reactor (such as rain cover, reactor coil, etc.), and the whole process is time-consuming, especially when using large equipment, the equipment scheduling and preparation time is further extended. According to statistics, the conventional pillar porcelain bottle replacement process requires 8 workers in 5 days to complete, resulting in a long power outage of the reactor, which seriously affects the operational reliability of the power grid.
[0005] Risks of high-altitude operations: Since the replacement of reactor support porcelain bottles usually involves high-altitude operations, such as using a crane or aerial vehicle to lift and support the equipment, high-voltage electric shock or mechanical collision accidents are prone to occur during the operation, posing a major safety hazard. Especially in places such as substations where high-voltage equipment is densely packed, the operation risks are further increased.
[0006] Equipment model restrictions: Existing support and lifting devices are usually fixed height or can only be adjusted to a limited extent, and cannot adapt to reactor equipment of different specifications and models. This lack of flexibility increases the difficulty of equipment replacement, and operators often need to make multiple adjustments according to different reactor models, which not only affects efficiency but also increases operational complexity.
[0007] High equipment costs: The use of large equipment such as cranes and aerial vehicles not only increases construction costs, but also requires professional operators, further increasing the overall cost of replacing pillar porcelain bottles. According to statistics, in the conventional replacement of pillar porcelain bottles, depending on site restrictions, it usually takes at least one 15T-25T crane for one day to complete. In the process of high-voltage power equipment maintenance, the expensive cost of using mechanical equipment makes the traditional method economically disadvantageous.
[0008] In summary, the existing method of replacing pillar porcelain bottles has problems such as high cost, complex operation, great safety hazards, and long construction time. There is an urgent need for an alternative solution that can improve efficiency, reduce risks, and reduce costs. Summary of the invention
[0009] The present invention aims to solve the deficiencies of the prior art and to provide a support porcelain bottle replacement device for a dry-type air-core reactor. The present invention can be applied to substation environments where the space is small and cranes and aerial vehicles are difficult to operate. By eccentric jacking, a gap is left for the replacement of the support porcelain bottle, thereby achieving efficient, safe and low-cost support porcelain bottle replacement.
[0010] The present invention is achieved through the following technical solutions:
[0011] A support porcelain bottle replacement device for a dry-type air-core reactor, comprising:
[0012] A support rod, the length of which is variable;
[0013] A hydraulic jack, wherein the hydraulic jack is fixed on the top of the support rod, the output end of the hydraulic jack faces upward, and a clamping block is provided on the output end, and the upper end of the clamping block has a clamping slot;
[0014] The card slot is transversely connected and has an open top;
[0015] The clamping block is used to lift the eccentric position of the dry-type air-core reactor, and the clamping groove can partially clamp the support bar at the bottom of the dry-type air-core reactor in the transverse penetration direction;
[0016] The slot is opened from the top to the bottom, and the distance between the two sides of the slot gradually decreases;
[0017] The bottom of the card slot is inclined downward from one side to the other side.
[0018] Compared with the prior art, in some substations with small sites or densely equipped environments, large equipment cannot be used, and the traditional solution for replacing supporting porcelain bottles usually requires the disassembly of the auxiliary structures of the reactor. The whole process is time-consuming, and there are great safety hazards in high-altitude operations, high costs, and complex operations. The present invention provides a supporting porcelain bottle replacement device for dry-type hollow reactors. The present invention can be used in substation environments with small sites and where cranes and aerial vehicles are difficult to operate. Through eccentric jacking, a gap for replacing the supporting porcelain bottles is left, thereby realizing efficient, safe, and low-cost replacement of supporting porcelain bottles. In the specific scheme, it includes a support rod with variable length, and the bottom of the support rod is provided with a support, which can be directly placed on the ground for support; the support rod itself includes a plurality of sub-rods connected in sequence, and the length of each sub-rod can be of different sizes to achieve height adjustment and assembly; adjacent sub-rods are detachably connected by connecting plates and bolts. By setting the support rod, it is convenient to place the support rod directly in the narrow space at the bottom of the dry-type air-core reactor; when it is connected to the required height, a hydraulic jack is set on the top of the support rod, and the hydraulic jack is manually controlled for jacking; in addition, since the bottom of the coil of the dry-type air-core reactor in the prior art is provided with a star-shaped bracket, the bracket has a plurality of struts extending outward in the circumferential direction, and each supporting porcelain bottle is supported on the corresponding strut, so in the process of jacking the upper coil, the upper coil can be jacked by inserting the card slot of the card block into the supporting bar at the corresponding position, so that the supporting bar and the supporting porcelain bottle are separated; and in the actual jacking process, since only one of the aged supporting porcelain bottles needs to be replaced, the jacking method is eccentric jacking, and the card slot is aligned with the supporting bar corresponding to the supporting porcelain bottle to be replaced, and it is jacked upward by about 10 mm, so that the inclination angle of the upper coil can be controlled while leaving an operating gap to avoid overturning due to excessive inclination angle. In addition, since it only needs to be lifted to a height of about 10 mm, the conventional electric-controlled lifting device cannot guarantee a smaller accuracy, which can easily lead to excessive lifting displacement; therefore, this scheme adopts the lifting method of a hydraulic jack, which can achieve precise adjustment of a small height through manual pressing control.
[0019] In summary, the support rod arrangement of this solution can facilitate support operations in the narrow space at the bottom of the dry-type air-core reactor, and the upper coil can be eccentrically lifted by the support rod and the clamping block. The required lifting force is small, and only a height of about 10 mm is required to leave an operating gap to complete the replacement of a certain pillar porcelain bottle, so as to achieve efficient, safe and low-cost replacement of the pillar porcelain bottle. Secondly, since the clamping block lifts the support bar, in order to ensure that the reactor coil does not tilt or slide during the lifting process, the slot is open from the top to the bottom, and the spacing on both sides of the slot gradually decreases, that is, the upper part is a wide-mouth design and the lower part is a narrow-mouth design, so that the support bar can be naturally slid into the bottom of the slot and firmly fixed. The V-shaped design is suitable for support bars of different widths, and the adjustment range of the slot is 50 mm to 200 mm, which is suitable for various types of reactors. Secondly, the bottom of the slot is tilted downward from one side to the other side. In this way, when lifting, the downward tilted side faces the axis of the coil, so that its tilt angle matches the slope of the support bar during lifting, so that the contact area between the slot and the support bar is increased after lifting, thereby further preventing it from sliding.
[0020] In order to realize the quick connection and installation of the hydraulic jack and prevent it from deflecting during the lifting process, the top of the support rod is provided with an annular support surface, and a plurality of slide grooves are evenly distributed on the circumferential end of the annular support surface, and the plurality of slide grooves are radially arranged along the annular support surface;
[0021] Each slide groove is slidably connected with a slider, the upper end of which is L-shaped and arranged toward the center of the annular support surface; the upper end of the slider is used to clamp the base of the hydraulic jack inside. In this solution, the base of the hydraulic jack can be directly placed on the annular support surface at the top of the support rod, and a plurality of slide grooves are provided in the circumferential direction of the annular support surface, and sliders are arranged on the slide grooves. In this way, the sliders can be adjusted according to the size of the base of the hydraulic jack, so that a plurality of sliders can be moved radially, thereby clamping the circumferential end of the base of the hydraulic jack inside, so as to achieve temporary fixation of the hydraulic jack.
[0022] In order to realize the sliding adjustment of the slider, the slider is a channel steel, and the slide groove is a through groove that passes through from top to bottom;
[0023] The width of the web of the channel steel is smaller than the width of the wing plates on both sides of the channel steel, and the width of the web of the channel steel is adapted to the width of the slideway; the bottom wing plates of the channel steel are threadedly connected with a number of vertically arranged bolts. In this scheme, the slider is set to the shape of the channel steel, or the channel steel is directly used, and the base of the hydraulic jack is clamped and fixed through the upper bent side surface; the width of the web of the bottom of the channel steel is smaller than the width of the wing plates on both sides, that is, the channel steel is I-shaped when viewed from the side, so that the web can be clamped into the slideway for sliding, and the wider wing plates on both sides can make the slider only move along the length direction of the slideway without falling; after being clamped into the base of the hydraulic jack, tighten the bolts on the bottom wing plates of the channel steel so that the bolts are pressed against the bottom of the annular support surface to achieve fixation.
[0024] In order to keep the pillar porcelain bottle stable when disassembling it under the condition of less manpower, such as when operating by one person, to avoid it from accidentally falling due to force during disassembly, a clamping bearing assembly is also included, and the clamping bearing assembly includes a cross bar, a longitudinal bar and a clamping bar, one end of the cross bar is connected to the side wall of the block, and the other end of the cross bar is arranged toward the direction of the pillar porcelain bottle to be replaced and connected to the middle part of the longitudinal bar;
[0025] A clamping rod is provided at both ends of the longitudinal rod, and the clamping rod is L-shaped. The upper end of the vertical side rod of the clamping rod is connected to the longitudinal rod, and the lateral side rod of the clamping rod extends toward the supporting porcelain bottle to be replaced; the two lateral side rods are used to clamp the skirt of the supporting porcelain bottle, and the distance between the two clamping rods is adjustable. In this scheme, a clamping bearing assembly is provided, and the clamping bearing assembly includes a cross bar, a longitudinal bar and a clamping rod. The cross bar is connected to the card block. If a card slot is provided on the back side of the card block away from the card slot, one end of the cross bar can be inserted into the card slot and connected by bolts; the other end of the cross bar extends toward the direction of the supporting porcelain bottle and is connected to the center of the longitudinal bar. The cross bar and the longitudinal bar are perpendicular to each other, and clamping rods are symmetrically provided at both ends of the longitudinal bar. At this time, the two clamping rods can be installed on both sides of the supporting porcelain bottle, and then the distance between the two clamping rods is adjusted so that the two clamping rods are clamped on the skirt of the supporting porcelain bottle facing each other, so that the stability of the supporting porcelain bottle can be maintained during the disassembly process, that is, at this time, the supporting porcelain bottle cannot be tilted in the front, back, left and right directions under the limiting effect.
[0026] If only the clamping block is connected, the single-point connection cannot ensure the stability of the clamping bearing assembly during the clamping installation process. Therefore, in order to improve the stability performance, the clamping bearing assembly also includes a first latch, and the support bar is provided with a reserved hole. The first latch and the reserved hole are matched in size and are used to pass through the reserved hole;
[0027] Two clamping plates are detachably connected to the top side of the middle part of the longitudinal rod, and both clamping plates are provided with a first through hole for the first pin to pass through; the two clamping plates are used to clamp the two sides of the support bar. In this scheme, a number of conventional reserved holes are opened at the position of the support bar close to the supporting porcelain bottle, and the first bolt can be inserted into the reserved hole at this time. The first bolt is a screw rod, and then a clamping plate is respectively inserted into the two ends of the first bolt, so that the two clamping plates clamp the two sides of the middle support bar. Since the first bolt is a screw rod, nuts can be screwed into the two ends of the first bolt, and the two clamping plates are pressed against each other to achieve fixation. At this time, under the action of the two clamping plates, the shaking of the entire clamping bearing assembly can be avoided, and the stability is improved; and the two-point connection is achieved through the first bolt and the block, which further improves the stability performance.
[0028] In order to realize the quick detachable connection between the clamping plate and the longitudinal rod, the clamping bearing assembly also includes a second latch, and two connecting plates are fixed on the top side of the middle part of the longitudinal rod, and the two clamping plates are located between the two connecting plates; the clamping plate and the connecting plate are both provided with a second through hole for the second latch to pass through. In this solution, the second latch is also a screw, which is inserted into the connecting plate, the clamping plate, the clamping plate and the connecting plate in sequence, and nuts are screwed into the two second latches between the clamping plate and the connecting plate to tighten the clamping plate and the connecting plate, improve stability, and realize detachable connection.
[0029] In order to adapt to the curvature of the insulator porcelain skirt and the width of the gap at the insulator porcelain skirt, thereby achieving stable clamping and facilitating the rapid sliding out of the pillar porcelain bottle, the two lateral side rods have curved surfaces on their opposite surfaces, the curved surfaces are adapted to the curved surfaces of the skirts of the pillar porcelain bottle, and the length direction of the curved surfaces is arranged along the length direction of the lateral side rods;
[0030] The transverse side bar comprises a horizontal section and an inclined section connected to each other, wherein the inclined section is located at one end of the transverse side bar away from the vertical side bar, and the end of the inclined section away from the vertical side bar is inclined downward; a horizontal bubble meter is arranged on the outer side of the inclined section;
[0031] The arc surface on the inclined section is higher than the arc surface on the horizontal section, and a flexible layer is provided between the arc surface on the inclined section and the inclined section. In this solution, the opposite surface of the transverse side bar has an arc surface, which gradually bends inward from top to bottom, and has adapted to the curvature of the porcelain skirt to ensure the stability of the clamping; secondly, since the pillar porcelain bottle has a certain weight, if the pillar porcelain bottle is taken out manually, it is likely to collide with the circumferential equipment during the process of taking and pulling, causing damage to the pillar porcelain bottle. Therefore, in order to facilitate the removal of the pillar porcelain bottle, the length of its arc surface is set along the length direction of the transverse side bar. In this way, when the pillar porcelain bottle is disassembled, the pillar porcelain bottle can be pushed out horizontally along the length direction of the transverse side bar to make the pillar porcelain bottle leave its original position, and a new pillar porcelain bottle can be re-inserted at the outer end of the transverse side bar to achieve installation in a stable process. In addition, an inclined section is provided at the outer end of the lateral side rod, and the inclined section is inclined downward at a certain angle. In this way, through the setting of the inclined section, the inclined section is initially clamped in the porcelain skirt, and then under the jacking action, the coil and the clamping bearing assembly on the top are gradually tilted, and the horizontal bubble gauge is parallel to the inclined section. When the horizontal bubble gauge on the outside of the inclined section reaches a horizontal state, it means that it has been jacked into place to a height of about 10 mm; therefore, the accuracy of manual jacking can be further improved by using the horizontal bubble gauge on the outside of the inclined section; the length from the reserved hole to the pillar porcelain skirt is constant, and the inclination angle of its inclined section can be set to a fixed value, so as to adapt to a variety of reactors. Secondly, a flexible layer is padded inside the arc surface on the inclined section. When the inclined section is inserted into the gap of the porcelain skirt, due to the limited width of the gap, as the inclined section moves upward and gradually becomes horizontal, it will squeeze the side wall of the porcelain skirt. Therefore, by setting a flexible layer, the height of the arc surface on the inclined section can be adjusted and flexible support can be achieved; after the disassembly of the support porcelain bottle is completed, the support porcelain bottle is slid inward so that the support porcelain bottle slides to the horizontal section. At this time, the horizontal section is in an inclined state, and the inclined section is in a horizontal state. The inclined horizontal section can prevent the support porcelain bottle from sliding; when the disassembled support porcelain bottle is located on the horizontal section, the installation position at the inclined section is vacated, and then a new support porcelain bottle is inserted into the opening position of the inclined section to complete the stable installation during the clamping process. The length of the above-mentioned vertical side rod is set at an elevation so that the inclined section of the clamping rod can enter the gap below the porcelain skirt and be fine-tuned through the flexible layer.
[0032] In order to adjust the spacing between the two clamping rods, the upper end of the vertical side rod of the clamping rod is slidably connected to the longitudinal rod through a sliding sleeve and can slide along the length direction of the longitudinal rod; the top side of the longitudinal rod has a long groove, and the long groove is arranged along the length direction of the longitudinal rod; the top of the sliding sleeve has a threaded hole that passes through itself, and the threaded hole is used to connect the bolt, and the bolt can extend into the long groove. In this scheme, the clamping rod is slidably sleeved on the longitudinal rod through the sliding sleeve to achieve longitudinal sliding and spacing adjustment; the top side of the longitudinal rod has a long groove, and the bolt can be screwed into the top of the sliding sleeve, so that the bolt extends into and presses against the bottom of the long groove to achieve temporary fixation of the clamping rod.
[0033] In order to realize the clamping and resetting between the two clamping rods and provide a certain pulling force in the opposite direction, a mounting tube is also provided on the bottom side of the longitudinal rod in the inner direction of the sliding sleeve. The mounting tube is arranged along the length direction of the longitudinal rod and is provided with a spring inside. The end of the spring extends out of the mounting tube and is connected to the sliding sleeve. The spring is used to apply a pulling force to the sliding sleeve. In this scheme, the mounting tube is used to install the spring, one end of the spring extends out of the mounting tube, and an intermediate plate is provided at one end of the spring. The connection between the spring and the clamping rod can be realized by bolting the intermediate plate and the clamping rod. The spring always provides a pulling force. In this way, the clamping rods of the two clamping rods can be raised by the pulling force of the spring, and can be automatically clamped and reset; it can also prevent the clamping rod from opening the clamping mouth during the clamping process.
[0034] In order to improve the stability of the support rod, facilitate the placement of the pillar porcelain bottle, and avoid collision damage caused by carrying the pillar porcelain bottle, a bearing plate is also included, which is connected between the side wall of the support rod and the glass fiber reinforced plastic pillar used to support the pillar porcelain bottle; the middle part of the bearing plate is provided with a material receiving tube for placing the pillar porcelain bottle. In this scheme, the pillar porcelain bottle is supported by the glass fiber reinforced plastic pillar, and the glass fiber reinforced plastic pillar and the support rod are connected by the bearing plate, so as to fix the support rod, and provide a certain stepping space for the operator through the bearing plate; in addition, holes can be provided on the bearing plate, and the material receiving tube is placed in the hole to facilitate the placement of the pillar porcelain bottle; by placing the pillar porcelain bottle in the material receiving tube, it is convenient for the operator to install other parts; after the disassembled pillar porcelain bottle is slid out, the new pillar porcelain bottle in the material receiving tube can be taken out for installation, and the disassembled pillar porcelain bottle can be placed in, and finally the material receiving tube can be taken out.
[0035] Compared with the prior art, the present invention has the following advantages and beneficial effects:
[0036] 1. The present invention provides a support porcelain bottle replacement device for a dry-type air-core reactor. By adopting this solution, it can be suitable for substation environments with narrow space and where cranes and aerial vehicles are difficult to operate. Through eccentric jacking, a gap for replacing the support porcelain bottle is left, thereby realizing efficient, safe and low-cost support porcelain bottle replacement work.
[0037] 2. The present invention provides a support porcelain bottle replacement device for a dry-type air-core reactor, which uses an eccentric lifting method. The card slot is aligned with the support bar corresponding to the support porcelain bottle to be replaced, and the support is lifted upward by about 10 mm. This can control the inclination angle of the upper coil while leaving an operating gap to avoid overturning due to excessive inclination. In addition, since it only needs to be lifted to a height of about 10 mm, conventional electric-controlled lifting devices cannot guarantee a smaller accuracy, which can easily lead to excessive lifting displacement; therefore, this solution adopts a hydraulic jack lifting method, which can achieve precise adjustment of a small height through manual pressure control.
[0038] 3. The present invention provides a support porcelain bottle replacement device for a dry-type air-core reactor, which has a plurality of slide grooves in the circumferential direction of the annular support surface, and a slider is arranged on the slide groove. In this way, the slider can be adjusted according to the base size of the hydraulic jack, so that the plurality of sliders can be moved radially, thereby clamping the circumferential end of the base of the hydraulic jack to achieve temporary fixation of the hydraulic jack.
[0039] 4. The present invention provides a support porcelain bottle replacement device for a dry-type air-core reactor, which can hold the bearing assembly to keep the support porcelain bottle stable when removing the support porcelain bottle in a situation with less manpower, such as when operated by a single person, to avoid it from accidentally falling due to force during removal. After the support porcelain bottle is removed, it can be pushed out laterally along the length direction of the lateral side rod to move it out of its original position, and a new support porcelain bottle can be re-inserted at the outer end of the lateral side rod, to avoid collision damage to the support porcelain bottle during the process of picking up and pulling.
[0040] 5. The support porcelain bottle replacement equipment for dry-type air-core reactors provided by the present invention can further improve the accuracy of manual lifting through the horizontal bubble meter on the outside of the inclined section; the length from the reserved hole to the support porcelain skirt is constant, and the inclination angle of the inclined section can be set to a fixed value, so as to adapt to a variety of reactors. Secondly, a flexible layer is padded in the arc surface on the inclined section. When the inclined section is inserted into the gap of the porcelain skirt, the height of the arc surface on the inclined section can be adjusted by setting the flexible layer, and flexible support can be achieved; after the disassembly of the support porcelain bottle is completed, the support porcelain bottle is slid inward, so that the support porcelain bottle slides to the horizontal section. At this time, the horizontal section is in an inclined state, and the inclined section is in a horizontal state. The inclined horizontal section can prevent the support porcelain bottle from sliding; when the disassembled support porcelain bottle is located on the horizontal section, the installation position at the inclined section has been vacated, and then a new support porcelain bottle is inserted into the opening position of the inclined section, so that stable installation can be completed during the clamping process.

DETAILED DESCRIPTION
[0053] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.
[0054] Embodiment 1:
[0055] This embodiment 1 provides a support porcelain bottle replacement device for a dry-type air-core reactor, such as Figure 1-Figure 5 As shown, including:
[0056] A support rod 1, wherein the length of the support rod 1 is variable;
[0057] A hydraulic jack 2, wherein the hydraulic jack 2 is fixed on the top of the support rod 1, the output end of the hydraulic jack 2 faces upward, and a clamping block 3 is provided on the output end, and a clamping groove 301 is provided on the upper end of the clamping block 3;
[0058] The card slot 301 is horizontally through and has an open top;
[0059] The clamping block 3 is used to lift the eccentric position of the dry-type air-core reactor, and the clamping groove 301 can partially clamp the support bar 5 at the bottom of the dry-type air-core reactor in the transverse penetration direction;
[0060] The slot 301 is opened from the top to the bottom, and the distance between the two sides of the slot 301 gradually decreases;
[0061] The bottom of the slot 301 is inclined downward from one side to the other side.
[0062] Compared with the prior art, in some substations with small sites or densely equipped environments, large equipment cannot be used, and the traditional replacement scheme of the support porcelain bottle 16 usually requires the disassembly of the auxiliary structure of the reactor. The whole process is time-consuming, and there are great safety hazards in high-altitude operations, high costs, and complex operations. The present invention provides a replacement device for the support porcelain bottle 16 of a dry-type air-core reactor. The present invention can be used in substation environments with small sites and difficult to operate cranes and aerial vehicles. Through eccentric jacking, a gap for the replacement of the support porcelain bottle 16 is left, so that efficient, safe, and low-cost replacement of the support porcelain bottle 16 can be achieved. In the specific scheme, it includes a support rod 1 with a variable length, and the bottom of the support rod 1 is provided with a support, which can be directly placed on the ground for support; the support rod 1 itself includes a plurality of sub-rods connected in sequence, and the length of each sub-rod can be of different sizes to achieve height adjustment and assembly; adjacent sub-rods are detachably connected through a connecting plate and bolts 104. By setting the support rod 1, it is convenient to place the support rod 1 directly in the narrow space at the bottom of the dry-type air-core reactor; when connected to the required height, a hydraulic jack 2 is set on the top of the support rod 1, and the hydraulic jack 2 is manually controlled to lift; in addition, since the bottom of the coil 4 of the dry-type air-core reactor in the prior art has a star-shaped bracket, the bracket has a plurality of struts 5 extending outward in the circumferential direction, and each support porcelain bottle 16 is supported on the corresponding strut 5, so in the process of lifting the upper coil 4, the block 3 is The slot 301 can be inserted into the corresponding position of the support bar 5 to lift the upper coil 4, so that the support bar 5 and the supporting porcelain bottle 16 are separated; and in the actual lifting process, since only one of the aged supporting porcelain bottles 16 needs to be replaced, the lifting method is eccentric lifting, and the slot 301 is placed directly on the support bar 5 corresponding to the supporting porcelain bottle 16 to be replaced, and lifted upward to a height of about 10 mm, so that the inclination angle of the upper coil 4 can be controlled while leaving an operating gap, to avoid overturning due to excessive inclination angle. In addition, since only about 10 mm of height needs to be lifted, the conventional electric-controlled lifting device cannot guarantee a smaller accuracy, which easily leads to excessive lifting displacement; therefore, this solution adopts the lifting method of the hydraulic jack 2, which can achieve precise adjustment of a small height through manual pressing control.
[0063] In summary, the way in which the support rod 1 is arranged in this scheme can facilitate the support operation in the narrow space at the bottom of the dry-type air-core reactor, and the upper coil 4 is eccentrically lifted by the support rod 1 and the block 3. The required lifting force is small, and only a height of about 10 mm is required to be lifted, leaving an operating gap, so that the replacement of a certain pillar porcelain bottle 16 can be completed, so as to achieve efficient, safe and low-cost replacement of the pillar porcelain bottle 16. Secondly, since the block 3 is used to lift the support bar 5, in order to ensure that the reactor coil 4 does not tilt or slide during the lifting process, the slot 301 is opened from the top to the bottom, and the spacing between the two sides of the slot 301 gradually decreases, that is, the upper part is a wide-mouth design and the lower part is a narrow-mouth design, so that the support bar 5 can be naturally slid into the bottom of the slot 301 and firmly fixed. The V-shaped design is suitable for support bars 5 of different widths, and the adjustment range of the slot 301 is 50 mm to 200 mm, which is suitable for various types of reactors. Secondly, the bottom of the slot 301 is tilted downward from one side to the other side, so that when lifting, the downward tilted side faces the axis of the coil 4, so that its tilt angle is matched with the slope of the support bar 5 during lifting, so that the contact area between the slot 301 and the support bar 5 is increased after lifting, thereby further preventing it from sliding.
[0064] In order to realize the quick connection and installation of the hydraulic jack 2 and prevent it from deflecting during the lifting process, the top of the support rod 1 is provided with an annular support surface 101, and a plurality of slide grooves 102 are evenly distributed on the circumferential end of the annular support surface 101, and the plurality of slide grooves 102 are radially arranged along the annular support surface 101;
[0065] Each slide groove 102 is slidably connected with a slider 103, the upper end of the slider 103 is L-shaped and is arranged toward the center of the annular support surface 101; the upper end of the slider 103 is used to clamp the base of the hydraulic jack 2 inside. In this solution, the base of the hydraulic jack 2 can be directly placed on the annular support surface 101 at the top of the support rod 1, and there are several slide grooves 102 in the circumferential direction of the annular support surface 101, and sliders 103 are arranged on the slide grooves 102. In this way, the sliders 103 can be adjusted according to the base size of the hydraulic jack 2, so that several sliders 103 move radially, thereby clamping the circumferential end of the base of the hydraulic jack 2 inside, so as to achieve temporary fixation of the hydraulic jack 2.
[0066] In order to achieve sliding adjustment of the slider 103, the slider 103 is a channel steel, and the slide groove 102 is a through groove that passes through from top to bottom;
[0067] The width of the web of the channel steel is smaller than the width of the wing plates on both sides of the channel steel, and the width of the web of the channel steel is adapted to the width of the slide 102; the bottom wing plates of the channel steel are threadedly connected with a plurality of vertically arranged bolts 104. In this scheme, the slider 103 is set to the shape of the channel steel, or the channel steel is directly used, and the base of the hydraulic jack 2 is clamped and fixed through the upper bent side surface; the width of the web of the bottom of the channel steel is smaller than the width of the wing plates on both sides, that is, the channel steel is I-shaped when viewed from the side, so that the web can be clamped into the slide 102 for sliding, and the slider 103 can only move along the length direction of the slide 102 through the wider wing plates on both sides, and will not fall; after being clamped into the base of the hydraulic jack 2, the bolts 104 on the bottom wing plates of the channel steel are tightened so that the bolts 104 are pressed against the bottom of the annular support surface 101 to achieve fixation.
[0068] Embodiment 2:
[0069] This embodiment 2 is further optimized on the basis of embodiment 1, such as Figure 6-Figure 9 As shown, a specific structure of a clamping bearing assembly is also provided.
[0070] In order to keep the support porcelain bottle 16 stable when removing the support porcelain bottle 16 under the condition of less manpower, such as when a single person is operating, so as to avoid it from accidentally falling due to force during removal, a clamping bearing assembly is also included, and the clamping bearing assembly includes a cross bar 6, a longitudinal bar 7 and a clamping rod 8, one end of the cross bar 6 is connected to the side wall of the block 3, and the other end of the cross bar 6 is arranged toward the support porcelain bottle 16 to be replaced, and is connected to the middle part of the longitudinal bar 7;
[0071] A clamping rod 8 is provided at both ends of the longitudinal rod 7, and the clamping rod 8 is L-shaped. The upper end of the vertical side rod of the clamping rod 8 is connected to the longitudinal rod 7, and the lateral side rod of the clamping rod 8 extends toward the supporting porcelain bottle 16 to be replaced; the two lateral side rods are used to clamp the skirt of the supporting porcelain bottle 16, and the distance between the two clamping rods 8 is adjustable. In this scheme, a clamping bearing assembly is provided, and the clamping bearing assembly includes a cross bar 6, a longitudinal bar 7 and a clamping rod 8. The cross bar 6 is connected to the block 3. If a snap-in groove is provided on the back side of the block 3 away from the snap-in groove 301, one end of the cross bar 6 can be inserted into the snap-in groove and connected by a bolt 104; the other end of the cross bar 6 extends toward the support porcelain bottle 16 and is connected to the center of the longitudinal bar 7. The cross bar 6 and the longitudinal bar 7 are perpendicular to each other, and the clamping rods 8 are symmetrically provided at both ends of the longitudinal bar 7. At this time, the two clamping rods 8 can be installed on both sides of the support porcelain bottle 16, and then the distance between the two clamping rods 8 is adjusted so that the two clamping rods 8 are clamped on the skirt of the support porcelain bottle 16 facing each other, so that the stability of the support porcelain bottle 16 can be maintained during the disassembly process, that is, at this time, the support porcelain bottle 16 cannot be tilted in the front, back, left and right directions under the limiting effect.
[0072] If only the clamp block 3 is connected, the single-point connection cannot ensure the stability of the clamping bearing assembly during the clamping installation process. Therefore, in order to improve the stability performance, the clamping bearing assembly further includes a first latch 9, and the support bar 5 is provided with a reserved hole. The first latch 9 is matched with the reserved hole in size and is used to pass through the reserved hole.
[0073] Two clamping plates 10 are detachably connected to the top side of the middle part of the longitudinal rod 7, and both clamping plates 10 are provided with first through holes for the first latch 9 to pass through; the two clamping plates 10 are used to clamp the two sides of the support bar 5. In this scheme, a number of conventional reserved holes are opened at the position of the support bar 5 close to the supporting porcelain bottle 16, and the first latch 9 can be inserted into the reserved holes at this time. The first latch 9 is a screw rod, and then a clamping plate 10 is respectively inserted at both ends of the first latch 9, so that the two clamping plates 10 clamp the two sides of the middle support bar 5. Since the first latch 9 is a screw rod, nuts can be screwed into the two ends of the first latch 9 to tighten the two clamping plates 10 to achieve fixation. At this time, under the action of the two clamping plates 10, the entire clamping bearing assembly can be prevented from shaking, thereby improving stability; and two-point connection is achieved through the first latch 9 and the block 3, further improving the stability performance.
[0074] In order to realize the quick detachable connection between the clamping plate 10 and the longitudinal rod 7, the clamping bearing assembly further includes a second latch 12. Two connecting plates 11 are also fixed to the top side of the middle of the longitudinal rod 7. The two clamping plates 10 are located between the two connecting plates 11. The clamping plate 10 and the connecting plate 11 are both provided with a second through hole for the second latch 12 to pass through. In this solution, the second latch 12 is also a screw, which is inserted into the connecting plate 11, the clamping plate 10, the clamping plate 10 and the connecting plate 11 in sequence, and nuts are screwed into the two second latches 12 between the clamping plate 10 and the connecting plate 11 to tighten the clamping plate 10 and the connecting plate 11, improve stability, and realize detachable connection.
[0075] In order to adapt to the curvature of the insulator porcelain skirt and the width of the gap at the insulator porcelain skirt, thereby achieving stable clamping and facilitating the rapid sliding out of the pillar porcelain bottle 16, the two lateral side rods have curved surfaces 801 on their opposite surfaces, and the curved surfaces 801 are adapted to the curved surfaces 801 of the skirts of the pillar porcelain bottle 16, and the length direction of the curved surfaces 801 is arranged along the length direction of the lateral side rods;
[0076] The lateral side bar comprises a horizontal section 806 and an inclined section 802 connected to each other. The inclined section 802 is located at one end of the lateral side bar away from the vertical side bar, and the end of the inclined section 802 away from the vertical side bar is inclined downward. A horizontal bubble gauge 18 is arranged on the outer side of the inclined section 802.
[0077] The arc surface 801 on the inclined section 802 is higher than the arc surface 801 on the horizontal section 806, and a flexible layer 803 is provided between the arc surface 801 on the inclined section 802 and the inclined section 802. In this solution, the opposite surface of the transverse side bar is provided with an arc surface 801, and the arc surface 801 gradually bends inward from top to bottom, which has adapted to the curvature of the porcelain skirt to ensure the stability of the clamping; secondly, since the pillar porcelain bottle 16 has a certain weight, if the pillar porcelain bottle 16 is taken out manually, it is likely to collide with the circumferential equipment during the process of taking and pulling, resulting in damage to the pillar porcelain bottle 16. Therefore, in order to facilitate the removal of the pillar porcelain bottle 16, the length of the arc surface 801 is set along the length direction of the transverse side bar. In this way, when the pillar porcelain bottle 16 is disassembled, the pillar porcelain bottle 16 can be pushed out horizontally along the length direction of the transverse side bar, so that the pillar porcelain bottle 16 leaves the original position, and a new pillar porcelain bottle 16 can be re-inserted at the outer end of the transverse side bar to achieve installation in a stable process. In addition, an inclined section 802 is provided at the outer end of the lateral side rod, and the inclined section 802 is inclined downward at a certain angle. In this way, through the setting of the inclined section 802, the inclined section 802 is initially clamped in the porcelain skirt, and then under the jacking action, the top coil 4 and the clamping bearing assembly are gradually tilted, and the horizontal bubble gauge 18 is parallel to the inclined section 802. When the horizontal bubble gauge 18 on the outside of the inclined section 802 reaches a horizontal state, it means that it has been jacked into place to a height of about 10 mm; therefore, the accuracy of manual jacking can be further improved by using the horizontal bubble gauge 18 on the outside of the inclined section 802; the length from the reserved hole to the pillar porcelain skirt is certain, and the inclination angle of its inclined section 802 can be set to a fixed value, so as to adapt to a variety of reactors. Secondly, a flexible layer 803 is padded inside the arc surface 801 on the inclined section 802. When the inclined section 802 is inserted into the gap of the porcelain skirt, due to the limited width of the gap, as the inclined section 802 moves upward and gradually becomes horizontal, it will squeeze the side wall of the porcelain skirt. Therefore, by setting the flexible layer 803, the height of the arc surface 801 on the inclined section 802 can be adjusted, and flexible support can be achieved; when the disassembly of the support porcelain bottle 16 is completed, the support porcelain bottle 16 is slid inward so that the support porcelain bottle 16 slides onto the horizontal section 806. At this time, the horizontal section 806 is in an inclined state, and the inclined section 802 is in a horizontal state. The inclined horizontal section 806 can prevent the support porcelain bottle 16 from sliding; when the disassembled support porcelain bottle 16 is located on the horizontal section 806, the installation position at the inclined section 802 is vacated, and then a new support porcelain bottle 16 is inserted into the opening position of the inclined section 802, and a stable installation can be completed during the clamping process. The length of the vertical side rod is set at an elevation so that the inclined section 802 of the clamping rod 8 can enter the gap below the porcelain skirt and be fine-tuned through the flexible layer 803.
[0078] In order to adjust the spacing between the two clamping rods 8, the upper end of the vertical side rod of the clamping rod 8 is slidably connected to the longitudinal rod 7 through a sliding sleeve 804, and can slide along the length direction of the longitudinal rod 7; the longitudinal rod 7 has a long groove 701 on the top side, and the long groove 701 is arranged along the length direction of the longitudinal rod 7; the top of the sliding sleeve 804 has a threaded hole 805 that passes through itself, and the threaded hole 805 is used to connect the bolt 104, and the bolt 104 can extend into the long groove 701. In this solution, the clamping rod 8 is slidably sleeved on the longitudinal rod 7 through the sliding sleeve 804 to achieve longitudinal sliding and spacing adjustment; the longitudinal rod 7 has a long groove 701 on the top side, and the bolt 104 can be screwed into the top of the sliding sleeve 804, so that the bolt 104 extends into and presses against the bottom of the long groove 701, so as to achieve temporary fixation of the clamping rod 8.
[0079] In order to realize the clamping and resetting between the two clamping rods 8 and provide a certain pulling force in the opposite direction, a mounting tube 13 is further provided on the bottom side of the longitudinal rod 7 in the inner direction of the sliding sleeve 804. The mounting tube 13 is arranged along the length direction of the longitudinal rod 7 and is provided with a spring inside. The end of the spring extends out of the mounting tube 13 and is connected to the sliding sleeve 804. The spring is used to apply a pulling force to the sliding sleeve 804. In this scheme, the mounting tube 13 is used to install the spring. One end of the spring extends out of the mounting tube 13, and an intermediate plate is provided at one end of the spring. The connection between the spring and the clamping rod 8 can be realized by connecting the bolt 104 between the intermediate plate and the clamping rod 8. The spring always provides a pulling force. In this way, the clamping rod 8 of the two clamping rods 8 can be raised by the pulling force of the spring, and can be automatically clamped and reset; it can also prevent the clamping rod 8 from opening the clamping port during the clamping process.
[0080] In order to improve the stability of the support rod 1 and facilitate the placement of the pillar porcelain bottle 16, and avoid collision damage caused by carrying the pillar porcelain bottle 16, it also includes a bearing plate 14, which is connected between the side wall of the support rod 1 and the fiberglass pillar 15 used to support the pillar porcelain bottle 16; the middle part of the bearing plate 14 is provided with a receiving tube 17 for placing the pillar porcelain bottle 16. In this scheme, the pillar porcelain bottle 16 is supported by the fiberglass pillar 15, and the fiberglass pillar 15 and the support rod 1 are connected by a bearing plate 14, so as to fix the support rod 1 and provide a certain stepping space for the operator through the bearing plate 14; in addition, holes can be provided on the bearing plate 14, and a receiving tube 17 is placed in the hole to facilitate the placement of the pillar porcelain bottle 16; by placing the pillar porcelain bottle 16 in the receiving tube 17, it is convenient for the operator to install other parts; after the disassembled pillar porcelain bottle 16 is slid out, the new pillar porcelain bottle 16 in the receiving tube 17 can be taken out for installation, and the disassembled pillar porcelain bottle 16 can be placed in, and finally the receiving tube 17 can be taken out.
[0081] How this solution works:
[0082] When it is necessary to replace a certain supporting porcelain bottle 16 at the bottom of the reactor, install the support rod 1 near the corresponding supporting porcelain bottle 16 and adjust its length; then install the hydraulic jack 2 on the top of the support rod 1, and install the clamping block 3 on the top of the hydraulic jack 2, so that the upper support bar 5 can be clamped into it through the clamping groove 301 of the clamping block 3, thereby realizing the eccentric lifting of the upper coil 4.
[0083] Then, a bearing plate 14 is installed on the side wall of the support rod 1 to facilitate the operator to step on it, and a bearing cylinder 17 is placed to place the support porcelain bottle 16; then, the upper clamping bearing assembly is installed, that is, the first latch 9 is inserted into the reserved hole on the support bar 5, and the clamping plates 10 are clamped at both ends to clamp the support bar 5; one end of the cross bar 6 is connected to the clamping block 3. The other end is connected to the center of the longitudinal rod 7, and the longitudinal rod 7 is connected to the clamping plate 10; then, the clamping rod 8 is clamped at both ends of the longitudinal rod 7, and the clamping rod 8 is connected to the spring; after the installation is completed, the clamping rod 8 is located on both sides of the support porcelain bottle 16 to be disassembled, and is clamped towards each other under the tension of the spring, and the clamping rod 8 is fixed at this time.
[0084] In the above clamping process, the inclined section 802 is clamped in the skirt gap of the supporting porcelain bottle 16, and a flexible layer 803 is provided on the inclined section 802 to realize the height adjustment and flexible clamping of the arc surface 801; then the upper coil 4 is eccentrically lifted, and when the horizontal bubble meter 18 at the inclined section 802 is in a horizontal state, it means that it has been lifted into place, and a disassembly gap of about 10 mm has been left above the supporting porcelain bottle 16 to be disassembled, and the disassembly of the supporting porcelain bottle 16 is completed at this time.
[0085] When the disassembly is completed, slide the support porcelain bottle 16 inward along the arc surface 801 so that the support porcelain bottle 16 is located on the horizontal section 806, and then take out a new support porcelain bottle 16, insert it into the opening of the inclined section 802, and install it by stable clamping; after the installation is completed, open the two clamping rods 8, take out the replaced support porcelain bottle 16, and put it into the receiving tube 17 below, and then disassemble the upper parts.
