Description

Technical Field

[0001] The invention belongs to the technical field of insulator production equipment, and in particular relates to a shade drying device for wet insulator blanks. Background Art

[0002] Insulators are devices installed between conductors of different potentials or between conductors and grounded components, and are able to withstand voltage and mechanical stress. Insulators are of various types and shapes. Although the structures and appearances of different types of insulators are quite different, they are all composed of two major parts: insulating parts and connecting fittings.

[0003] Insulators are a special type of insulating control that can play an important role in overhead transmission lines. In the early years, insulators were mostly used on telegraph poles, and gradually developed into high-voltage power lines. Many disc-shaped insulators are hung on one end of the tower to increase the creepage distance. They are usually made of glass or ceramics and are called insulators.

[0004] A Chinese patent with the authorization announcement number CN220524581U discloses a disc-shaped suspended porcelain insulator rapid shade drying device, including a rapid shade drying machine, a conveying platform fixedly connected inside the rapid shade drying machine, a hot air furnace with a fan fixedly installed on the front side of the rapid shade drying machine, a gas pipeline fixedly connected to the top of the hot air furnace, a rotating air cavity opened on the top of the rapid shade drying machine, a blowing fan fixedly installed inside the rotating air cavity, and a uniform heat dissipation pipeline with an upper opening fixedly connected to the upper surface of the inner wall of the rapid shade drying machine. This comparative document realizes that the heated hot air is uniformly sent into the rapid shade drying machine by setting a hot air furnace and a uniform heat dissipation pipeline through the cooperation of the above structures, two conveying platforms can repeatedly and slowly transport the semi-finished blanks to receive hot air for shade drying, and a secondary dehumidification frame is added to accelerate the drying and dehumidification of the disc-shaped suspension porcelain insulators that are dried without cracking, thereby ensuring the rapid shade drying efficiency of the disc-shaped suspension porcelain insulators.

[0005] In the above technical solution, the insulator is directly placed flat on the surface of the conveyor table and the rotating tray for shade drying or hot air drying. Since the bottom surface of the insulator is in full surface contact with the supporting surface, an air circulation barrier layer is formed in the contact area. Since the contact surface is continuously in a relatively closed state, its water evaporation rate is significantly lower than the exposed surface of the non-contact area. This difference in drying rate will form an uneven stress distribution inside the insulator body. When the local moisture content gradient exceeds the tolerance limit of the material, it will cause microstructural cracking defects, and eventually lead to macro cracks in the insulator product or even functional failure. Summary of the invention

[0006] The object of the present invention is to provide a wet blank drying device for insulators, aiming to solve the problem that when the existing rapid drying equipment for disc suspension porcelain insulators dries or bakes the insulators, it is easy to have uneven drying, resulting in cracking of the insulators.

[0007] To achieve the above object, the present invention provides the following technical solution: A wet blank drying device for insulators, comprising: a drying chamber and an annular track installed in the drying chamber, on which a plurality of placement racks are slidably installed, and the placement rack includes: A bracket, slidably installed on the annular track and capable of sliding along the track of the annular track; A first placement component, installed on the bracket, and the first placement component includes a first lifting component for placing an insulator above it, and the first lifting component can drive the insulator to rotate, and its rotation axis is perpendicular to the ground; A second placement component, slidably moving up and down on the bracket, and the second placement component includes a second lifting component, and the second lifting component can lift the insulator off the placement surface of the first lifting component; When the second placement component moves closer to the first placement component, the first lifting component will drive the insulator to rotate. When the second placement component lifts the insulator off the first lifting component, the first lifting component reversely resets.

[0008] A further technical solution of the present invention is that a swing rod is provided on the first lifting component, a wedge block is provided at the end of the swing rod far from the first lifting component, a push column sliding horizontally is provided on the second placement component, and a second elastic member for resetting the push column is further provided on one side of the push column. When the second placement component drives the push column to move upward, the push column can contact the inclined surface of the wedge block and push the wedge block to move to one side.

[0009] A further technical solution of the present invention is that the first placement component further includes an extension rod fixed on the bracket, the first lifting component rotates at the end of the extension rod far from the bracket through a first elastic member, and a positioning column abuting against one side of the swing rod is provided on the extension rod. When the first lifting component rotates, it can store energy for the first elastic member, and when the first elastic member releases energy, the positioning column can limit the rotation of the first lifting component through the swing rod.

[0010] A further technical solution of the present invention is that a lifting column sliding up and down along the length direction of the bracket is provided inside the bracket, the second placement component is installed on the lifting column, an undulating groove is provided inside the inner side of the annular track, a sliding column sliding inside the undulating groove is provided at the top of the lifting column, and the top end of the bracket abuts against the bottom of the annular track.

[0011] A further technical solution of the present invention is that a lifting plate is provided on the lifting column, and the second lifting component is installed at one end of the lifting plate away from the lifting column. The second lifting component includes a connecting plate fixedly connected to the lifting plate, and a supporting ring rotatably mounted on the connecting plate. A swing arm is fixedly connected to the rotating shaft of the supporting ring and the connecting plate. One end of the swing arm away from the supporting ring is fixedly connected with a pressing column, and the pressing column is located directly below the extension rod. When the second lifting component moves upward, the extension rod will press down on the pressing column, causing the supporting ring to flip upward.

[0012] A further technical solution of the present invention is that a limiting block is installed on the connecting plate, and the limiting block can abut against the pressing column. When the limiting block abuts against the pressing column, the supporting ring is in a horizontal state.

[0013] A further technical solution of the present invention is that a first positioning plate and a second positioning plate are respectively provided on the first lifting component and the second lifting component. The first positioning plate corresponds to the second lifting component and is used to abut against the insulator when the second lifting component is tilted. The second positioning plate corresponds to the first lifting component and is used to position the position where the staff places the insulator.

[0014] A further technical solution of the present invention is that the wedge block has two mutually parallel inclined surfaces. When the push column moves upward, the wedge block is pushed to move through the lower inclined surface. When the push column moves downward, the push column is pushed to move in the horizontal direction through the upper inclined surface, and the second elastic member is compressed.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By the combined use of the first placement component and the second placement component, the insulator can rotate slowly on the first placement component, and the contact position between the insulator and the first placement component can be continuously changed. Thus, it can be avoided that the placement surface of the insulator is always unable to effectively contact the air, resulting in uneven drying and cracking of the insulator.

[0016] 2. When drying the insulator, the insulator can be flipped by a certain angle so that the concave part of the insulator faces outward. Thus, the circulating air can more easily pass through the concave part of the insulator, and it is more convenient for the air to take away the moisture in the concave part of the insulator, thereby improving the drying efficiency of the insulator.

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-10, the present invention provides the following technical solution: an insulator green blank drying device, including a drying chamber 1, a circular track 2 and a placement rack 3; Please refer to Figure 1 and Figure 2 , wherein, the placement rack 3 is used to stably place the insulator 4, the placement rack 3 is slidably installed on the circular track 2, and the placement rack 3 is driven by a circular slide rail (not shown in the figure) to slide along the circular track 2. The circular track 2 is fixed on the drying chamber 1. By driving the placement rack 3 to move along the circular track 2 through the circular slide rail, the placement rack 3 drives the insulator 4 to slowly move inside the drying chamber 1, and the insulator 4 is dried.

[0021] The drying chamber 1 is designed with multiple layers. In this embodiment, a double-layer (upper layer and lower layer) design is adopted, and the upper layer and the lower layer are interconnected through a communication port. The circular track 2 can pass through the communication port from the lower layer to the upper layer. By setting the drying chamber 1 with multiple layers, the length of the track can be increased, the drying time of the insulator 4 can be increased, and at the same time, the temperature and humidity in each layer of the drying chamber 1 can be adjusted respectively, so that it can be applicable to insulators 4 with different humidities and different thicknesses to improve the drying efficiency; It should be noted that the adjustment of the internal temperature and humidity of the drying chamber 1 is prior art and will not be elaborated in detail here.

[0022] A loading section 11 is provided at the lower layer of the drying chamber 1. The staff places the wet blank of the insulator 4 on the placement rack 3 through the loading section 11. An unloading section 12 is provided on one side of the upper layer of the drying chamber 1. The circular track 2 passes through the unloading section 12 to the outside of the drying chamber 1 and extends obliquely downward to a position flush with the lower layer, so that it is convenient for the staff to take away the dried insulator 4 on the placement rack 3. Then the circular track 2 turns backward and re-passes through the lower layer of the drying chamber 1 to form a complete circle.

[0023] A plurality of ventilation openings 13 are provided at both the upper layer and the lower layer of the drying chamber 1, so that the air inside the drying chamber 1 circulates, improving the drying efficiency inside the drying chamber 1. At the same time, a circulation fan can be provided at the ventilation opening 13 to improve the ventilation effect inside the drying chamber 1.

[0024] Please refer to Figure 2 and Figure 3 , a plurality of fixing plates 21 are fixedly connected to one side of the circular track 2. The fixing plates 21 can be fixed to the circular track 2 through welding. One end of the fixing plate 21 away from the circular track 2 is installed at the indoor top of the drying chamber 1, that is, the indoor top of the lower layer and the upper layer. There needs to be a certain distance between the placement rack 3 and the indoor ground of the drying chamber 1 to avoid ground interference with the movement of the placement rack 3. When installing the circular track 2, it can be fixed by screws, which is also convenient for disassembling and repairing the circular track 2.

[0025] Please refer to Figures 3-5 , the placement rack 3 includes a bracket 31, and a sliding member 32 is rotatably connected above the bracket 31. The sliding member 32 slides on the annular track 2. Specifically, a first sliding groove 22 extending along the length direction of the annular track 2 is provided above the annular track 2. The sliding member 32 is lapped on the annular track 2, and a slider 321 capable of sliding inside the first sliding groove 22 is provided, so that the sliding member 32 can slide on the annular track 2 and at the same time can avoid derailing from the annular track 2. The top of the bracket 31 abuts against the bottom of the annular track 2 to prevent the slider 321 from derailing from the inside of the first sliding groove 22. Since the sliding member 32 and the bracket 31 are rotatably connected, an arc surface is provided at the top of the bracket 31 to avoid interference between the bracket 31 and the annular track 2 during rotation.

[0026] Please refer to Figures 4-8 , a plurality of first placement components 33 are provided on the bracket 31. After the plurality of first placement components 33 are annularly arrayed in 3 - 4 and then longitudinally arrayed in 3 - 5 for uniform distribution. The first placement component 33 includes an extension rod 331 fixed on the bracket 31. The extension rod 331 is in a horizontal direction and extends away from the bracket 31. A first lifting component 332 is provided on the extension rod 331. The insulator 4 can be horizontally placed on the first lifting component 332. The setting of multiple groups of first placement components 33 can place multiple insulators 4 on one bracket 31 and drive the insulator 4 to move along with the bracket 31 by moving the bracket 31 along the annular track 2.

[0027] The first lifting component 332 is composed of a plurality of annularly arrayed cross - plates. In this embodiment, three cross - plates are adopted. The insulator 4 can be lifted by the three cross - plates. In the middle of the first lifting component 332 (the axis of the annular array of cross - plates), it is rotatably connected to the end of the extension rod 331 away from the bracket 31 through a rotating shaft and penetrates below the bracket 31. A first elastic member 333 is provided between the rotating shaft and the extension rod 331. The first elastic member 333 is a torsion spring, which is used to reset the rotation angle of the first lifting component 332 through the rotating shaft. A swing rod 334 is provided at the end of the rotating shaft away from the first lifting component 332. A positioning column 335 abuting against the swing rod 334 is provided at the bottom of the extension rod 331. Under the action of the first elastic member 333, the swing rod 334 abuts against the positioning column 335, so that the initial position of the first lifting component 332 can be positioned.

[0028] Please refer to Figures 5-9, a second placement component 34 is further provided on the support 31. The number of the second placement components 34 is the same as that of the first placement components 33, and each second placement component 34 is correspondingly placed below each first placement component 33. The second placement component 34 includes a lifting plate 341 that can slide up and down along the support 31. A plurality of lifting plates 341 are all fixed on a lifting column 342, and the lifting column 342 can slide up and down inside the support 31. One end of the lifting plate 341 away from the lifting column 342 is provided with a second lifting component 343. The second lifting component 343 can completely cover the first lifting component 332. The second lifting component 343 is in a circular ring shape, and a plurality of support plates (the vertical direction of the support plates preferably has the same vertical direction as that of the cross plates) are arranged inside the second lifting component 343. A plurality of cross plates and a plurality of support plates are arranged crosswise with each other. That is to say, a support plate is arranged between every two cross plates. When the lifting plate 341 drives the second lifting component 343 to move upward, the support plate can pass through the gap between the cross plates, cross over the cross plates to lift the insulator 4 upward, and lift the insulator 4 away from the cross plate by a certain distance.

[0029] Please refer to Figures 6-9 , one end of the swing rod 334 away from the first elastic member 333 extends downward to form a vertical plate 336. A wedge block 337 is fixed at the bottom of the vertical plate 336. The wedge block 337 has two parallel inclined surfaces. A push column 344 that slides horizontally is provided on the second placement component 34. A second elastic member 345 for resetting the push column 344 is further provided on one side of the push column 344. When the second lifting component 343 moves upward, it can abut against one inclined surface of the wedge block 337, so that the swing rod 334 can be driven by the vertical plate 336 to rotate in a direction away from the positioning column 335, and at the same time, the first elastic member 333 is energized. When the second lifting component 343 continues to move upward, the push column 344 disengages from the wedge block 337, and the first lifting component 332 is reset under the action of the first elastic member 333.

[0030] The specific working principle is as follows. When the second placement component 34 moves upward, the second lifting component 343 drives the push rod 344 to move upward, causing the push rod 344 to contact the inclined surface of the wedge block 337. Then, during the continuous upward movement of the second lifting component 343, the push rod 344 pushes the vertical plate 336 and the swing rod 334 to rotate a certain angle around the rotating shaft through the inclined surface of the wedge block 337, thereby driving the insulator 4 to rotate a certain angle. When the push rod 344 is about to disengage from the wedge block 337, the second lifting component 343 lifts the insulator 4 from the first lifting component 332, preventing the insulator 4 from coming into contact with the first lifting component 332. Further, since the wedge block 337 has a certain thickness (thickness in the vertical direction), when the push rod 344 disengages from the inclined surface of the wedge block 337, the second lifting component 343 can just lift the insulator 4 from the first lifting component 332. Then, through the transition in the thickness direction of the wedge block 337, the second lifting component 343 can completely lift the insulator 4 from the first lifting component 332, avoiding contact between the insulator 4 and the first lifting component 332. After the push rod 344 disengages from the wedge block 337, under the action of the energy release of the first elastic member 333, the first lifting component 332 is reset and positioned by the positioning post 335. Then, the second placement component 34 moves downward, causing the push rod 344 to abut against the other inclined surface of the wedge block 337. Since the rotation of the first lifting component 332 to the other side is limited by the positioning post 335, the push rod 344 can slide to one side under the push of the inclined surface, and at the same time, the second elastic member 345 is compressed. When the push rod 344 completely disengages from the wedge block 337, the second elastic member 345 resets the push rod 344. Through multiple repetitions of the above actions, the insulator 4 can slowly rotate on the first lifting component 332, thereby enabling the replacement of the supported part of the insulator 4, avoiding the problem of uneven drying of the insulator 4 caused by the relatively airtight contact surface. At the same time, due to the rotation of the insulator 4, the windward surface of the insulator 4 (the surface opposite to the air flow direction when the air circulates) can be continuously replaced, enabling each surface of the insulator 4 to uniformly contact the air flow, thereby further making the drying of the insulator 4 more uniform.

[0031] Please refer to Figure 5 and Figure 10, in order to enable the second lifting component 343 to move up and down, undulating grooves 23 are provided on the inner side of the annular track 2. Specifically, the undulating grooves 23 have an upper sliding surface and a lower sliding surface, which are alternately interspersed in reality, and the upper sliding surface and the lower sliding surface are connected by inclined surfaces. A sliding column 24 that slides inside the undulating groove 23 is provided at the top of the lifting column 342. When the placement rack 3 moves along the annular track 2, since the top of the bracket 31 abuts against the bottom of the annular track 2, when the sliding column 24 moves along the upper sliding surface, inclined surface and lower sliding surface of the undulating groove 23, it can drive the lifting column 342 to move up and down inside the bracket 31.

[0032] Please refer to Figure 8 , the second lifting component 343 includes a connecting plate 3431 fixedly connected to the lifting plate 341, and a supporting ring 3432 rotatably mounted on the connecting plate 3431. An oscillating arm 3433 is fixedly connected to the rotating shaft of the supporting ring 3432 and the connecting plate 3431. A pressing column 3434 is fixedly connected to the end of the oscillating arm 3433 away from the supporting ring 3432. The pressing column 3434 is located directly below the extension rod 331. A limiting block 3435 is installed on the connecting plate 3431, and the limiting block 3435 can abut against the pressing column 3434. The self-weight of the supporting ring 3432 will cause the supporting ring 3432 to be in a drooping state. Therefore, by abutting the limiting block 3435 against one side of the pressing column 3434, the supporting ring 3432 can overcome its own gravity and remain in a horizontal state. When the second lifting component 343 moves upward, the extension rod 331 will contact the pressing column 3434 and press down the pressing column 3434. Through the lever principle, the supporting ring 3432 drives the insulator 4 to turn up by a certain angle, so that the concave part of the insulator 4 faces outward. Therefore, when the air circulates, it is easier to contact the concave surface of the insulator 4, making it easier for the air flow to take away the moisture in the concave part of the insulator 4, thereby improving the drying efficiency of the insulator 4.

[0033] Please refer to Figure 9 , a second sliding groove is provided on the connecting plate 3431. The pushing column 344 slides inside the second sliding groove, and the second elastic member 345 is also provided inside the second sliding groove. Since the pushing column 344 is located at one end of the second sliding groove in the initial state, when the pushing column 344 pushes the wedge block 337 to move, the pushing column 344 can be prevented from sliding inside the second sliding groove.

[0034] Please refer to Figure 8, multiple pallets are fixed on the support ring 3432. A first positioning plate 5 is provided on the pallet. The first positioning plate 5 can slide horizontally on the pallet and its position can be adjusted by screws. By providing the first positioning plate 5, the position of the insulator 4 can be limited to prevent the insulator 4 from slipping off the support ring 3432 when the support ring 3432 is in an inclined state. A second positioning plate 6 is provided on the cross plate. The second positioning plate 6 slides on the cross plate and its position is usually adjusted by screws to position the position where the staff places the insulator 4.
