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 at different potentials, or between a conductor and a grounded structure, to withstand voltage and mechanical stress. Insulators come in many different types and shapes. While their structures and appearances vary significantly, they all consist of two main components: the insulating element and the connecting hardware.

[0003] Insulators are specialized insulating components that play a vital role in overhead transmission lines. Initially, they were primarily used on utility poles. They gradually evolved into high-voltage power lines, where a series of disc-shaped insulators, typically made of glass or ceramic, are hung on one end of a tower to increase creepage distance.

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

[0005] In the above-mentioned technical solution, insulators are placed directly flat on the surface of a conveyor table and rotating tray for shade drying or hot air drying. Since the bottom surface of the insulator forms a complete surface contact with the supporting surface, an air flow barrier forms in the contact area. Because this contact surface remains relatively closed, its moisture evaporation rate is significantly lower than that of the exposed surface in the non-contact area. This difference in drying rate creates an uneven stress distribution within the insulator body. When the local moisture content gradient exceeds the material's tolerance limit, it will induce microstructural cracking defects, ultimately leading to macroscopic cracks and even functional failure of the insulator product. Summary of the Invention

[0006] The purpose of the present invention is to provide a device for drying wet blanks of insulators in the shade, aiming to solve the problem that uneven drying occurs when the disc-shaped suspension porcelain insulator rapid shade drying equipment in the prior art shade dries or bakes the insulators, resulting in cracking of the insulators.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: an insulator green blank shade drying device, comprising: a shade drying chamber and a ring track installed in the shade drying chamber, a plurality of placement racks being slidably mounted on the ring track, the placement racks comprising:

[0008] The bracket is slidably mounted on the annular track and can slide along the track of the annular track;

[0009] a first placement assembly mounted on the bracket, the first placement assembly comprising a first lifting assembly for placing an insulator thereon, the first lifting assembly being capable of driving the insulator to rotate, with its rotation axis being perpendicular to the ground;

[0010] A second placement assembly slides up and down on the bracket, the second placement assembly includes a second lifting assembly, and the second lifting assembly can lift the insulator off the placement surface of the first lifting assembly;

[0011] When the second placement assembly moves toward the first placement assembly, the first lifting assembly drives the insulator to rotate. When the second placement assembly lifts the insulator off the first lifting assembly, the first lifting assembly reverses and resets.

[0012] A further technical solution of the present invention is that a rocker arm is provided on the first supporting component, a wedge block is provided at the end of the rocker arm away from the first supporting component, a push column sliding in the horizontal direction is provided on the second placing component, and a second elastic member for resetting the push column is also provided on one side of the push column. When the second placing 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 one side.

[0013] A further technical solution of the present invention is that the first placement component also includes an extension rod, which is fixed on the bracket. The first lifting component is rotated on the end of the extension rod away from the bracket through the first elastic member. A positioning column is provided on the extension rod, which is against one side of the rocker arm. When the first lifting component rotates, it can store force on the first elastic member. When the first elastic member releases energy, the positioning column can limit the rotation of the first lifting component through the rocker arm.

[0014] A further technical solution of the present invention is that a lifting column that slides 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, the inner side of the circular track is provided with an undulating groove, and a sliding column that slides along the inside of the undulating groove is provided on the top of the lifting column, and the top end of the bracket is abutted against the bottom end of the circular track.

[0015] A further technical solution of the present invention is that a lifting plate is provided on the lifting column, and a second lifting assembly is installed at an end of the lifting plate away from the lifting column. The second lifting assembly includes a connecting plate fixedly connected to the lifting plate, and a supporting ring rotating on the connecting plate. A swing arm is fixedly connected to the rotating axis of the supporting ring and the connecting plate, and a pressure column is fixedly connected to the end of the swing arm away from the supporting ring. The pressure column is located directly below the extension rod. When the second lifting assembly moves upward, the extension rod will press the pressure column downward, causing the supporting ring to flip upward.

[0016] A further technical solution of the present invention is that a limit block is installed on the connecting plate, and the limit block can be against the pressure column. When the limit block and the pressure column are against each other, the support ring is in a horizontal state.

[0017] 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 supporting assembly and the second supporting assembly, wherein the first positioning plate corresponds to the second supporting assembly and is used to counteract the insulator when the second supporting assembly is tilted, and the second positioning plate corresponds to the first supporting assembly and is used to locate the position where the staff places the insulator.

[0018] A further technical solution of the present invention is that the wedge block has two parallel inclined surfaces. When the push column moves upward, the wedge block is pushed to move by the inclined surface located below. When the push column moves downward, the push column is pushed to move in the horizontal direction by the inclined surface located above, and the second elastic member is compressed.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. By using the first placement component and the second placement component in conjunction with each other, the insulator can be slowly rotated on the first placement component, and the contact position between the insulator and the first placement component can be continuously changed, thereby avoiding the problem that the placement surface of the insulator cannot always effectively contact with the air, causing uneven drying and leading to cracking of the insulator.

[0021] 2. When drying the insulator, the insulator can be turned over at a certain angle so that the concave part of the insulator faces outward, making it easier for the circulating air to pass through the concave part of the insulator, making it easier for the air to take away the moisture in the concave part of the insulator, thereby improving the drying efficiency of the insulator.

DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] See also Figures 1-10 The present invention provides the following technical solutions: an insulator wet blank shade drying device, comprising a shade drying chamber 1, a ring track 2 and a placement rack 3;

[0036] See also Figure 1 and Figure 2 , wherein the placement rack 3 is used to place the insulator 4 stably, the placement rack 3 is slidably installed on the annular track 2, and the placement rack 3 is driven by an annular slide rail (not shown in the figure) to slide along the annular track 2, and the annular track 2 is fixed on the drying chamber 1. The placement rack 3 is driven by the annular slide rail to move along the annular track 2, so that the placement rack 3 drives the insulator 4 to move slowly inside the drying chamber 1 to perform a shade drying treatment on the insulator 4.

[0037] The drying chamber 1 is multi-layered, and in this embodiment, a double-layer (upper and lower) design is adopted. The upper and lower layers are interconnected via a connecting port, and the annular track 2 can pass through the connecting port from the lower layer to the upper layer. By arranging the drying chamber 1 into multiple layers, the length of the track can be increased, thereby improving the drying time of the insulator 4. At the same time, the temperature and humidity in each layer of the drying chamber 1 can be adjusted separately, so that it can be used for insulators 4 of different humidity and thickness, thereby improving the drying efficiency.

[0038] It should be noted that the adjustment of the temperature and humidity inside the drying chamber 1 is a conventional technique and will not be described in detail here.

[0039] A loading part 11 is provided at the lower layer of the drying chamber 1. The staff places the wet insulator 4 on the placement rack 3 through the loading part 11. A unloading part 12 is provided on one side of the upper layer of the drying chamber 1. The circular track 2 passes through the unloading part 12 to the outside of the drying chamber 1, and extends downward at an angle to a position flush with the lower layer, so that the staff can easily remove the insulator 4 that has been dried on the placement rack 3. After that, the circular track 2 rotates backward and passes through the lower layer of the drying chamber 1 again, forming a complete ring.

[0040] Multiple ventilation holes 13 are provided at the upper and lower layers of the drying room 1 to allow air to circulate inside the drying room 1 and improve the drying efficiency in the drying room 1. At the same time, a circulating fan can be provided at the ventilation holes 13 to improve the ventilation effect in the drying room 1.

[0041] See also Figure 2 and Figure 3 A plurality of fixing plates 21 are fixedly connected to one side of the circular track 2, and the fixing plates 21 and the circular track 2 can be fixed by welding. The end of the fixing plate 21 away from the circular track 2 is installed on the indoor ceiling of the drying room 1, that is, the indoor ceiling of the lower and upper layers. There needs to be a certain distance between the placement rack 3 and the floor inside the drying room 1 to avoid the ground interfering with the movement of the placement rack 3. When the circular track 2 is installed, it can be fixed by screws, which is also convenient for disassembly and maintenance of the circular track 2.

[0042] See also Figure 3-Figure 5 The placing 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 slide groove 22 extending along the length direction of the annular track 2 is provided above the annular track 2. The sliding member 32 is overlapped on the annular track 2 and is provided with a slider 321 that can slide inside the first slide groove 22, so that the slider 32 can slide on the annular track 2 while avoiding derailment from the annular track 2. The top of the bracket 31 is against the bottom of the annular track 2 to avoid the slider 321 from derailing from the inside of the first slide groove 22. Since the sliding member 32 and the bracket 31 are rotatably connected, an arc surface is provided on the top of the bracket 31 to avoid interference between the bracket 31 and the annular track 2 during rotation.

[0043] See also Figure 4-Figure 8 A plurality of first placement components 33 are provided on the bracket 31. The plurality of first placement components 33 are arranged in a circular array of 3-4 and then evenly distributed in a longitudinal array of 3-5. The first placement component 33 includes an extension rod 331 fixed on the bracket 31. The extension rod 331 is horizontal and extends away from the bracket 31. A first supporting component 332 is provided on the extension rod 331. The insulator 4 can be placed horizontally on the first supporting component 332. The arrangement of multiple groups of first placement components 33 can place multiple insulators 4 on one bracket 31, and move along the circular track 2 through the bracket 31, thereby driving the insulator 4 to follow the movement of the bracket 31.

[0044] The first lifting component 332 is composed of a plurality of circular arrays of horizontal plates. In this embodiment, three horizontal plates are used, and the insulator 4 can be lifted by the three horizontal plates. In the middle part of the first lifting component 332 (the axis of the circular array of horizontal plates), the end of the extension rod 331 away from the bracket 31 is rotated by the rotating shaft and passes through the bottom of 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 rocker rod 334 is provided at the end of the rotating shaft away from the first lifting component 332. A positioning column 335 that abuts against the rocker rod 334 is provided at the bottom of the extension rod 331. Under the action of the first elastic member 333, the rocker rod 334 is abutted against the positioning column 335, so that the initial starting position of the first lifting component 332 can be positioned.

[0045] See also Figure 5-Figure 9 , a second placement component 34 is also provided on the bracket 31. The number of the second placement components 34 is the same as the number of the first placement components 33, and each second placement component 34 is correspondingly placed under each first placement component 33. The second placement component 34 includes a lifting plate 341 that can slide up and down along the bracket 31. The multiple lifting plates 341 are fixed on a lifting column 342. The lifting column 342 can slide up and down inside the bracket 31. The lifting plate 341 is away from the lifting column 342. The end of the lifting plate 341 is provided with a second lifting component 343. The second The supporting assembly 343 can completely cover the first supporting assembly 332. The second supporting assembly 343 is in a circular shape, and multiple supporting plates are arranged inside the second supporting assembly 343 (the vertical direction of the supporting plates is preferably the same as the vertical direction of the horizontal plates). The multiple horizontal plates and the multiple supporting plates are arranged crosswise with each other, that is, there is a supporting plate between every two horizontal plates. When the lifting plate 341 drives the second supporting assembly 343 to move upward, the supporting plate can pass through the gap between the horizontal plates, cross the horizontal plates to lift the insulator 4 upward, and lift the insulator 4 a distance away from the horizontal plates.

[0046] See also Figure 6-Figure 9 When the second lifting assembly 343 moves upward, it can resist the inclined surface of one side of the wedge block 337, thereby driving the rocker arm 334 to rotate in the direction away from the positioning column 335 through the vertical plate 336. At the same time, the first elastic member 333 accumulates force. When the second lifting assembly 343 continues to move upward, the push column 344 disengages from the wedge block 337, and the first lifting assembly 332 is reset under the action of the first elastic member 333.

[0047] The specific working principle is that when the second placement component 34 moves upward, the second supporting component 343 will drive the push column 344 to move upward, so that the push column 344 contacts the inclined surface of the wedge block 337. Then, as the second supporting component 343 continues to move upward, the push column 344 pushes the vertical plate 336 and the rocker 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 column 344 is about to disengage from the wedge block 337, the second supporting component 343 will lift the insulator 4 from the first supporting component The second supporting assembly 343 is lifted from the first supporting assembly 332 to prevent the insulator 4 from being released from the first supporting assembly 332. Furthermore, since the wedge block 337 has a certain thickness (thickness in the vertical direction), when the push pin 344 is separated from the inclined surface of the wedge block 337, the second supporting assembly 343 can just lift the insulator 4 from the first supporting assembly 332. Then, through the transition in the thickness direction of the wedge block 337, the second supporting assembly 343 can completely lift the insulator 4 from the first supporting assembly 332 to prevent the insulator 4 from contacting the first supporting assembly 332. Then, the push pin 344 is separated from the wedge block When the wedge block 337 is turned, the first lifting assembly 332 is reset under the action of the first elastic member 333 and positioned by the positioning post 335. Then the second placement assembly 34 moves downward so that the push post 344 can be against the inclined surface on the other side of the wedge block 337. Since the rotation of the first lifting assembly 332 to the other side is limited by the positioning post 335, the push post 344 can be pushed to one side by the inclined surface. At the same time, the second elastic member 345 is compressed. When the push post 344 is completely out of the wedge block 337, the push post 344 is pushed back by the second elastic member 345. The column 344 is reset, and the above-mentioned action is repeated many times, so that the insulator 4 can slowly rotate on the first supporting component 332, so that the supporting part of the insulator 4 can be replaced, avoiding the problem of uneven drying of the insulator 4 due to the relatively closed 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 direction of air flow when air circulates) can be continuously replaced, so that each surface of the insulator 4 can be evenly in contact with the airflow, thereby further making the insulator 4 dry more evenly.

[0048] See also Figure 5 and Figure 10In order to enable the second lifting component 343 to move up and down, an undulating groove 23 is provided on the inner side of the circular track 2. Specifically, the undulating groove 23 has an upper sliding surface and a lower sliding surface, which are alternately interspersed with the upper sliding surface and the lower sliding surface are connected by an inclined surface. A sliding column 24 that slides along the inside of the undulating groove 23 is provided on the top of the lifting column 342. When the placement rack 3 moves along the circular track 2, since the top of the bracket 31 is against the bottom of the circular track 2, the sliding column 24 can drive the lifting column 342 to move up and down inside the bracket 31 when it moves along the upper sliding surface, inclined surface and lower sliding surface of the undulating groove 23.

[0049] See also Figure 8 The second lifting assembly 343 includes a connecting plate 3431 fixedly connected to the lifting plate 341, and a supporting ring 3432 rotating on the connecting plate 3431. A swing arm 3433 is fixedly connected to the rotating axis of the supporting ring 3432 and the connecting plate 3431. The end of the swing arm 3433 away from the supporting ring 3432 is fixedly connected to a pressure column 3434. The pressure column 3434 is located just below the extension rod 331. A limit block 3435 is installed on the connecting plate 3431. The limit block 3435 can offset the pressure column 3434. The self-weight of the supporting ring 3432 will cause the supporting ring 3432 to be in a drooping state. The limit block 3435 is against one side of the pressure column 3434, so that the support ring 3432 overcomes its own gravity and remains in a horizontal state. When the second lifting component 343 moves upward, the extension rod 331 will contact the pressure column 3434 and press the pressure column 3434 downward. Through the lever principle, the support ring 3432 drives the insulator 4 to flip upward at 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 shade drying efficiency of the insulator 4.

[0050] See also Figure 9 A second slide groove is provided on the connecting plate 3431, the push column 344 slides inside the second slide groove, and the second elastic member 345 is also provided inside the second slide groove. Since the push column 344 is located at one end of the second slide groove in the initial state, when the push column 344 pushes the wedge block 337 to move, the push column 344 can be prevented from sliding inside the second slide groove.

[0051] See also Figure 8, multiple support plates are fixed on the support ring 3432, and a first positioning plate 5 is provided on the support plate. The first positioning plate 5 can slide horizontally on the support plate, and the position of the first positioning plate 5 can be adjusted by screws. Through the setting of the first positioning plate 5, the position of the insulator 4 can be limited to prevent the insulator 4 from sliding off the support ring 3432 when the support ring 3432 is in an inclined state. A second positioning plate 6 is provided on the horizontal plate, and the second positioning plate 6 slides on the horizontal plate. The position of the second positioning plate 6 is usually adjusted by screws to position the position where the insulator 4 is placed by the staff.
