Description

Technical Field

[0001] This invention relates to the field of warehousing and conveying technology, and in particular to a conveying device for insulator storage. Background Technology

[0002] In the insulator storage and transportation process, a semi-automated system combining conveyor belts and elevators is used. The conveyor belt transports the insulators to the warehouse area, the elevator lifts them to the corresponding floor height, and then they are manually pushed into the shelves. Although this reduces some of the handling distance, the conveying devices are mostly simple combinations of independent vertical lifting mechanisms and horizontal conveying mechanisms. The two movements are independent of each other, requiring frequent start-stop connections from the control system. This results in complex action sequences and a lot of idle travel, making it impossible to complete the entire process of picking, lifting, moving, and unloading in one cycle, thus limiting the transportation efficiency.

[0003] In addition, existing equipment lacks the function of cleaning the surface of insulators. Insulators are prone to dust and other impurities during production and transportation. If they enter the storage area with the products, they will not only pollute the warehouse environment, but may also affect the electrical performance and appearance quality of the insulators. In some cases where cleanliness is required, an additional independent cleaning station needs to be set up, which further lengthens the transportation process. More importantly, the insulators have special shapes, mostly disc-shaped or bell-shaped structures, with concave and convex surfaces at the top and bottom. They are prone to positional deviation during transportation, which can cause jamming or misalignment of the shelves when entering the warehouse. Currently, the position is corrected manually before entering the warehouse, which not only increases the labor intensity, but also limits the improvement of automation.

[0004] To address the aforementioned issues, it is necessary to develop a new type of insulator storage conveying device capable of continuous cyclic conveying, synchronous cleaning, and automatic correction. This would overcome the technical bottlenecks in existing technologies, such as complex operation sequences, lack of cleaning functions, and reliance on manual correction, and meet the demands of modern warehousing for efficient, clean, and precise operations. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the present invention provides a conveying device for insulator storage.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a conveying device for insulator storage, comprising a classification rack for layered storage of insulator boxes and a conveying rack for conveying insulator boxes, wherein a side frame is fixedly installed on the loading and unloading side of the classification rack, and a multi-layer lifting assembly is provided inside the side frame, the multi-layer lifting assembly being used to lift and convey the insulator boxes on the conveying rack to different layers of the classification rack as needed; The multi-layer lifting assembly includes a spiral movable plate and a lifting frame. Fixed gears are movably connected around the inside of the side frame, and a spiral chain is connected around the outside of the fixed gears. The upper and lower ends of the side frame are movably connected to the spiral movable plate through fixed rods. Movable blocks are movably connected inside the spiral movable plate, and the lifting frame is fixedly connected to the movable blocks. The top of the side frame is equipped with a pushing cleaning component. After the lifting frame in the multi-layer lifting assembly vertically lifts the insulator box to the highest point, it will move horizontally. During the horizontal movement, the lifting frame pushes the cleaning component to blow air and clean the dust on the upper surface of the insulator box. The cleaning assembly includes a cleaning cylinder fixedly installed on the top side of the sorting rack and an arc-shaped cleaning seat set on the top of the lifting rack; The top of the movable block is equipped with a fixed-point swing component, which drives the arc-shaped cleaning seat to swing and sweep air on the top side of the insulator box, so as to cover and clean the dust on the top of the insulator box from multiple angles and in all directions. A circular transfer frame is movably installed on the outer periphery of the side frame. A sliding alignment component is installed on the top of the circular transfer frame. The sliding alignment component is used to straighten the insulator boxes on the circular transfer frame and align the insulator boxes to be stored with the classification frame. The aligning assembly includes a U-shaped support frame and an arc-shaped pressing plate that moves the two ends of the insulator box.

[0007] As a preferred embodiment of the present invention, the conveyor frame is located at the bottom of the sorting frame. The conveyor frame performs horizontal packaging and conveying of the insulator boxes. The multi-layer lifting assembly also includes a first motor. The first motor is fixedly installed on the back of the side frame through a motor plate. The shaft of one of the fixed gears is fixedly installed at the output end of the first motor. A T-shaped groove is opened on the inner side of the U-shaped movable plate. A T-shaped slider is slidably connected in the T-shaped groove. A movable block is fixedly installed between the T-shaped sliders. A connecting rod is fixedly installed on the side of the movable block away from the lifting frame, and the connecting rod is fixedly installed at the center of the chain link.

[0008] A contactor is provided at the top center of the U-shaped movable plate, and an arc-shaped contact rod is fixedly installed on the top of the movable block to perform contact action on the contactor.

[0009] As a preferred embodiment of the present invention, the pushing cleaning assembly further includes a piston plate. A pushing rod is fixedly installed on the top of the U-shaped movable plate on the side near the sorting rack. The pushing rod extends through into the interior of the cleaning cylinder. The piston plate is movably arranged inside the cleaning cylinder. The top end of the pushing rod is fixedly installed at the center of the piston plate. An air outlet pipe and an air inlet pipe are provided at the end of the cleaning cylinder away from the U-shaped movable plate.

[0010] A rotating rod is fixedly installed on the top of the movable block, and a rotating plate is movably connected to the top of the rotating rod. An arc-shaped cleaning seat is fixedly installed on the end of the rotating plate away from the rotating rod. Several cleaning nozzles are evenly installed on the side of the arc-shaped cleaning seat away from the rotating rod. An air outlet pipe is connected to the arc-shaped cleaning seat, and the cleaning nozzles on the arc-shaped cleaning seat blow and clean the dust on the top of the insulator box.

[0011] As a preferred embodiment of the present invention, the fixed-point swing assembly further includes an L-shaped base plate fixedly installed on the top of the movable block. A second motor is fixedly installed on the top of the L-shaped base plate, and a drive arm is fixedly installed at the output end of the second motor. An arc-shaped drive rod is fixedly installed at the bottom of the drive arm. An arc-shaped rotating groove is opened on the rotating plate. The size of the arc-shaped rotating groove matches the size of the arc-shaped drive rod, and the arc-shaped drive rod moves within the arc-shaped rotating groove. Several lifting rollers are provided on the side of the lifting frame away from the side frame, and the lifting rollers move through the conveyor frame.

[0012] The side frame has a lifting frame fixedly installed on the side away from the lifting frame. A servo motor is fixedly installed inside the lifting frame. A screw is fixedly installed at the output end of the servo motor. A lifting block is threaded onto the screw. The lifting block is fixedly connected to the U-shaped transfer frame through a lifting rod. A limit rod is fixedly installed inside the lifting frame, and both ends of the lifting block move through the limit rod. The lifting frame has a lifting groove, and the lifting rod moves through the lifting groove.

[0013] As a preferred embodiment of the present invention, the rotary transfer frame is provided with several inlet and outlet rollers on the side near the sorting frame. The inlet and outlet rollers horizontally transport the insulator box, and the lifting rollers move alternately through the inlet and outlet rollers. The actuation alignment assembly also includes an electric telescopic rod. A U-shaped support frame is fixedly installed on the side of the rotary transfer frame away from the inlet and outlet rollers. An electric telescopic rod is fixedly installed on the top of the U-shaped support frame. A pressing rod is movably connected to the bottom of the electric telescopic rod. A support rotating rod is fixedly installed at the bottom of the U-shaped support frame. Arc-shaped pressing plates are movably connected to both ends of the support rotating rod, and the arc-shaped pressing plates move at both ends of the insulator box. Motion plates are movably connected to the bottom of the arc-shaped pressing plates at both ends of the pressing rod.

[0014] The U-shaped support frame has an arc-shaped support groove, and the size of the arc-shaped support groove matches the size of the lower pressure rod. The two ends of the lower pressure rod move through the arc-shaped support groove. An arc-shaped guide rod is fixedly installed on the top of the arc-shaped pressing plate. Several guide rings are movably connected to the arc-shaped guide rod, and the guide rings move against the two ends of the insulator box.

[0015] Compared with the prior art, the beneficial effects that this invention can achieve are: 1. In this invention, the composite motion structure of the loop-shaped movable plate and the movable block in the multi-layer lifting assembly, combined with the rectangular trajectory drive of the fixed gear and chain, enables the movable block to simultaneously complete the entire process of descending to pick up goods, horizontally moving to receive goods, rising to lift, and horizontally moving to deliver goods in one cycle. This integrates the traditional independent vertical lifting and horizontal conveying mechanisms into one unit, avoiding the complex action sequence problems caused by frequent start-stop connections of multiple mechanisms. This ensures a continuous and smooth conveying process without interruption or waiting. The movable block moves along the rectangular trajectory, completing horizontal displacement while lifting the insulator box, significantly reducing idle travel and non-working periods, significantly shortening the single conveying cycle, and increasing the throughput per unit time. At the same time, the T-shaped groove and T-shaped slider between the movable block and the loop-shaped movable plate, and the limiting cooperation between the loop-shaped movable plate and the fixed rod, ensure high-precision guidance during the movement process, making the lifting frame run smoothly and reliably, avoiding the risk of insulator box displacement or tipping due to shaking. This is especially suitable for insulator products with large weight and high center of gravity, effectively ensuring conveying safety.

[0016] 2. In this invention, the horizontal movement of the movable block drives the synchronous movement of the U-shaped movable plate. The piston plate is driven by the push rod to reciprocate within the cleaning cylinder, spraying compressed air through the cleaning nozzle to clean the top of the insulator box. This ingeniously transforms the horizontal movement of the lifting frame into a cleaning power source, eliminating the need for additional motors or air pumps. This achieves synchronous automatic cleaning during the conveying process, saving energy and simplifying the equipment structure. The cleaning action occurs precisely when the insulator box is lifted into position and about to be moved horizontally to the sorting rack. At this time, the box is in the "gap period" of the conveying process, and cleaning does not occupy extra time. This avoids the process lengthening and space occupation caused by setting up a separate cleaning station. The air inlet pipe of the cleaning cylinder is connected to an external drying and purification device. With the precise control of the one-way valve, the sprayed compressed air is ensured to be dry and clean, avoiding secondary pollution. By pushing the cleaning components, dust and particulate matter on the surface of the insulator box are effectively removed, preventing them from entering the storage area with the box and causing environmental pollution. At the same time, it ensures the surface cleanliness of the insulators during subsequent packaging, maintaining the electrical performance and appearance quality of the product.

[0017] 3. In this invention, the second motor in the fixed-point swing assembly drives the arc-shaped drive rod to slide within the arc-shaped rotating groove, forcing the rotating plate to swing back and forth around the rotating rod. This drives the arc-shaped cleaning seat and its cleaning nozzles to perform a fan-shaped sweeping airflow. The rotational motion of the second motor is converted into the reciprocating swinging motion of the arc-shaped cleaning seat, causing the airflow trajectory to spread out in a fan shape. The coverage area is far greater than that of a fixed spray structure. Insulators are mostly disc-shaped or bell-shaped structures with concave and convex curved surfaces and corner grooves on the top. Traditional fixed nozzles have difficulty reaching these dead corners. However, the swinging airflow can impact the surface of the box from multiple angles as the cleaning seat swings back and forth, ensuring that every inch of area is effectively cleaned. In particular, it achieves no dead corner coverage for hard-to-reach areas such as corners and grooves. By adjusting the speed and swing amplitude of the second motor, it can also adapt to insulator boxes of different sizes and specifications, achieving precise control of the cleaning effect and significantly improving the thoroughness of cleaning. This provides a high-cleanliness product guarantee for subsequent storage and packaging.

[0018] 4. In this invention, the electric telescopic rod in the alignment assembly drives the lower pressure rod to move along the arc-shaped support groove. The moving plate drives the arc-shaped pressure plate to swing inward around the support rod. The guide ring on the arc-shaped guide rod contacts both ends of the insulator box and adjusts it to the center position, realizing automatic and precise alignment of the insulator box. This completely eliminates the reliance on manual adjustment. The guide ring is movably sleeved on the arc-shaped guide rod and can rotate freely when in contact with both ends of the insulator box. This effectively transmits the adjustment force and avoids damage to the box surface caused by hard friction. It ensures that the box is aligned to a position that is strictly aligned with the entrance of the sorting rack shelf, eliminating the risk of jamming or deviation during entry. After the alignment is completed, the guide ring resets outward with the arc-shaped pressure plate without interfering with subsequent conveying. This not only reduces the intensity of manual labor but also improves the reliability and consistency of automated operation, laying a solid foundation for unmanned warehousing.

[0019] 5. In this invention, a servo motor drives a screw to rotate, which, in conjunction with a limiting rod for guidance, enables the lifting block to precisely raise and lower the circular transfer rack, achieving height alignment with different shelves of the sorting rack. The screw drive has a self-locking characteristic, maintaining a stable position even in the event of a power outage, preventing the circular transfer rack from sliding down due to gravity and causing safety accidents. The limiting rod passes through both ends of the lifting block, ensuring no swaying or shaking during the lifting process, and maintaining a strictly horizontal alignment between the inlet / outlet rollers and the target shelf. The lifting block is fixedly connected to the circular transfer rack via a lifting rod, resulting in a compact structure and high transmission rigidity, capable of supporting heavy insulator boxes without deformation. Through precise control of the servo motor, the circular transfer rack can quickly respond to storage needs at different shelf heights, enabling flexible switching between multi-layer sorting racks, significantly improving the utilization rate of storage space and the flexibility of inbound and outbound operations.

[0020] 6. In this invention, the lifting rollers intersect between the inlet and outlet rollers, enabling a smooth, unpowered transition of the insulator box between the lifting frame and the circular transfer frame. The "comb-tooth interlacing" design allows the lifting rollers to gradually enter the gap between the inlet and outlet rollers as the lifting frame descends, naturally lifting or receiving the box. This transfer is completed without any active pushing mechanism, avoiding impacts or jamming caused by power mismatch. The interlacing layout ensures continuous support points for the box, preventing any suspension or insufficient support. This effectively prevents the insulator box from tilting, swaying, or tipping over during the transition, making it particularly suitable for heavy insulator products. It ensures smooth and safe transport, simplifies the control system, and reduces equipment failure rates. Attached Figure Description

[0023] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0024] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a conveying device for insulator storage includes a sorting rack 10 for layered storage of insulator boxes and a conveying rack 11 for conveying the insulator boxes. A side frame 20 is fixedly installed on one side of the sorting rack 10 for loading and unloading. A multi-layer lifting assembly is provided inside the side frame 20 to lift and convey the insulator boxes on the conveying rack 11 to different layers of the sorting rack 10 as needed. The multi-layer lifting assembly includes a U-shaped movable plate 24 and a lifting frame 31. Fixed gears 21 are movably connected around the inside of the side frame 20, and a U-shaped chain 22 is connected to the outer periphery of the fixed gears 21. The upper and lower ends of the side frame 20 are movably connected to the U-shaped movable plate 24 via fixed rods 23. A movable block 30 is movably connected inside the U-shaped movable plate 24, and the lifting frame 31 is fixedly connected to the movable block 30. See Figure 1 , Figure 2, Figure 3 , Figure 4 and Figure 5 The conveyor frame 11 is located at the bottom of the sorting frame 10. The conveyor frame 11 performs horizontal packaging and conveying of the insulator boxes. The multi-layer lifting assembly also includes a first motor 25. The first motor 25 is fixedly installed on the back of the side frame 20 through a motor plate. The shaft of one of the fixed gears 21 is fixedly installed at the output end of the first motor 25. A T-shaped slide groove 26 is opened on the inner side of the U-shaped movable plate 24. A T-shaped slider 27 is slidably connected in the T-shaped slide groove 26. The movable block 30 is fixedly installed between the T-shaped sliders 27. A connecting rod 32 is fixedly installed on the side of the movable block 30 away from the lifting frame 31. The connecting rod 32 is fixedly installed at the center of the chain link of the chain 22. A contactor 34 is provided at the top center of the U-shaped movable plate 24. An arc-shaped contact rod 33 is fixedly installed on the top of the movable block 30 to perform contact action on the contactor 34.

[0025] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The conveyor frame 11 is located at the bottom of the sorting rack 10 and is used for horizontal packaging and conveying of the insulator boxes. The multi-layer lifting assembly is responsible for lifting the insulator boxes from the conveyor frame 11 to different heights. When the first motor 25 is started, it drives the fixed gear 21 to rotate, thereby driving the chain 22 to move in a cycle. A connecting rod 32 is fixed at the center of the chain link 22. The connecting rod 32 is connected to the movable block 30. The movable block 30 is installed in the T-shaped slide groove 26 inside the U-shaped movable plate 24 through the T-shaped slider 27, so that the movable block 30 can slide smoothly along the slide groove. One side of the movable block 30 is fixedly connected to the lifting frame 31. Therefore, the movement of the chain 22 drives the movable block 30 and the lifting frame 31 to rise and fall together through the connecting rod 32; a contactor 34 is set at the top center of the U-shaped movable plate 24, and an arc-shaped contact rod 33 is fixedly installed on the top of the movable block 30; when the movable block 30 moves to the top limit position with the chain 22, the arc-shaped contact rod 33 will touch the contactor 34, the contactor 34 will send an electrical signal to control the second motor 51 to work, thereby realizing the precise positioning or automatic reciprocating motion of the lifting frame 31. The multi-layer lifting assembly can smoothly and accurately lift the insulator box on the conveyor frame 11 to the specified layer height, and complete the automated conveying task.

[0026] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The top of the side frame 20 is equipped with a pushing cleaning component. After the lifting frame 31 in the multi-layer lifting component vertically lifts the insulator box to the highest point, it will move horizontally. During the horizontal movement, the lifting frame 31 pushes the cleaning component to blow air and clean the dust on the upper surface of the insulator box. See Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The cleaning assembly includes a cleaning cylinder 40 fixedly installed on the top side of the sorting rack 10, an arc-shaped cleaning seat 45 and a piston plate 41 set on the top of the lifting frame 31. A push rod 42 is fixedly installed on the top of the U-shaped movable plate 24 on the side close to the sorting rack 10. The push rod 42 extends through into the interior of the cleaning cylinder 40. The piston plate 41 is movably arranged inside the cleaning cylinder 40. The top end of the push rod 42 is fixedly installed at the center of the piston plate 41. An air outlet pipe 43 and an air inlet pipe 44 are provided at the end of the cleaning cylinder 40 away from the U-shaped movable plate 24.

[0027] See Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 A rotating rod 54 is fixedly installed on the top of the movable block 30. A rotating plate 55 is movably connected to the top of the rotating rod 54. An arc-shaped cleaning seat 45 is fixedly installed on the end of the rotating plate 55 away from the rotating rod 54. Several cleaning nozzles 46 are evenly installed on the side of the arc-shaped cleaning seat 45 away from the rotating rod 54. An air outlet pipe 43 is connected to the arc-shaped cleaning seat 45. The cleaning nozzles 46 on the arc-shaped cleaning seat 45 blow and clean the dust on the top of the insulator box.

[0028] See Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7During the operation of the multi-layer lifting assembly, the lifting frame 31 moves horizontally at the top of the side frame 20. Since the movable block 30 and the lifting frame 31 move horizontally synchronously, the movable block 30 will drive the U-shaped movable plate 24 to move horizontally synchronously within the fixed rod 23. When the U-shaped movable plate 24 moves towards the sorting rack 10, the push rod 42, which is fixedly installed at the top of the U-shaped movable plate 24, also moves horizontally. The top end of the push rod 42 extends into the cleaning cylinder 40 and is fixedly connected to the center of the piston plate 41. At this time, the push rod 42 pushes the piston plate 41 to move horizontally towards the sorting rack 10 within the cleaning cylinder 40, thus cleaning the inside of the cleaning cylinder 40. The air in the cleaning cylinder 40 is compressed and delivered to the arc-shaped cleaning seat 45 via the air outlet pipe 43 at the end of the cleaning cylinder 40. Finally, it is sprayed out by the evenly distributed cleaning nozzles 46 to blow away the dust on the top of the insulator box. When the U-shaped movable plate 24 moves away from the sorting rack 10, the push rod 42 pulls the piston plate 41 to move horizontally in the opposite direction. At this time, a negative pressure is formed inside the cleaning cylinder 40, which draws in outside air through the air inlet pipe 44 to replenish it, preparing for the next compressed air jet. The air drawn in by the air inlet pipe 44 is connected to an external drying and purification device, so that the subsequently discharged compressed air remains clean and pure, improving the cleaning effect on the top of the insulator box.

[0029] See Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The top of the movable block 30 is equipped with a fixed-point swing component, which drives the arc-shaped cleaning seat 45 to swing and sweep air on the top side of the insulator box, so as to cover and clean the dust on the top of the insulator box from multiple angles. The fixed-point swing component also includes an L-shaped base plate 50 fixedly installed on the top of the movable block 30. A second motor 51 is fixedly installed on the top of the L-shaped base plate 50. A drive arm 52 is fixedly installed at the output end of the second motor 51. An arc-shaped drive rod 53 is fixedly installed at the bottom of the drive arm 52. The rotating plate 55 has an arc-shaped rotating groove 56. The size of the arc-shaped rotating groove 56 matches the arc-shaped drive rod 53, and the arc-shaped drive rod 53 moves in the arc-shaped rotating groove 56. The lifting frame 31 has several lifting rollers 35 on the side away from the side frame 20, and the lifting rollers 35 move through the conveyor frame 11.

[0030] See Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7When the contactor 34 in the multi-layer lifting assembly is triggered, the second motor 51 in the fixed-point swing assembly starts, driving the drive arm 52 at the output end to rotate. The arc-shaped drive rod 53 fixed at the bottom of the drive arm 52 slides in the arc-shaped rotating groove 56 opened in the rotating plate 55. Since the rotating plate 55 is movably connected to the rotating rod 54 on the movable block 30, the movement of the arc-shaped drive rod 53 forces the rotating plate 55 to swing back and forth around the rotating rod 54, thereby driving the arc-shaped cleaning seat 45 and the cleaning nozzle 46 on it to swing back and forth, realizing precise dust blowing on different positions on the top of the insulator box, enhancing the cleaning coverage and effect.

[0031] See Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 A lifting frame 60 is fixedly installed on the side of the side frame 20 away from the lifting frame 31. A servo motor 61 is fixedly installed inside the lifting frame 60. A screw 62 is fixedly installed at the output end of the servo motor 61. A lifting block 63 is threadedly connected to the screw 62. The lifting block 63 is fixedly connected to the rotary transfer frame 65 through the lifting rod 64. A limit rod 66 is fixedly installed inside the lifting frame 60, and both ends of the lifting block 63 move through the limit rod 66. The lifting frame 60 has a lifting groove 67, and the lifting rod 64 moves through the lifting groove 67.

[0032] See Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The lifting frame 31 has multiple lifting rollers 35 on the side away from the side frame 20, and the lifting rollers 35 are movably inserted through the conveyor frame 11 to assist in the smooth transport of the insulator box during the lifting process. In the lifting section, a lifting frame 60 is fixedly installed on the other side of the side frame 20. The servo motor 61 inside the lifting frame 60 drives the screw 62 to rotate, so that the threaded lifting block 63 moves up and down along the screw 62, and is guided by the limit rod 66 to maintain the stability of vertical movement. The lifting block 63 is fixedly connected to the circular transfer frame 65 through the lifting rod 64 through the lifting groove 67 opened in the lifting frame 60, thereby driving the circular transfer frame 65 to rise and fall, realizing the accurate transfer of the insulator box between different height layers, and providing a reliable connection for subsequent packaging or conveying processes.

[0033] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8 and Figure 9A U-shaped transfer frame 65 is movably installed on the outer periphery of the side frame 20. A shifting alignment component is installed on the top of the U-shaped transfer frame 65. This component is used to align the insulator boxes on the U-shaped transfer frame 65, aligning the insulator boxes to be stored with the sorting frame 10. The shifting alignment component includes a U-shaped support frame 70 and an arc-shaped pressing plate 74 that shifts the insulator boxes at both ends. Several inlet and outlet rollers 68 are installed on the side of the U-shaped transfer frame 65 near the sorting frame 10. The inlet and outlet rollers 68 horizontally transport the insulator boxes, and lifting rollers 35 movably and alternately pass through the inlet and outlet rollers 68. In the output roller 68, the actuation alignment assembly also includes an electric telescopic rod 71. A U-shaped support frame 70 is fixedly installed on the side of the U-shaped transfer frame 65 away from the input and output rollers 68. An electric telescopic rod 71 is fixedly installed on the top of the U-shaped support frame 70. A pressing rod 72 is movably connected to the bottom of the electric telescopic rod 71. A support rotating rod 73 is fixedly installed at the bottom of the U-shaped support frame 70. Arc-shaped pressing plates 74 are movably connected to both ends of the support rotating rod 73. The arc-shaped pressing plates 74 are movably located at both ends of the insulator box. A moving plate 75 is movably connected to both ends of the pressing rod 72 and the bottom of the arc-shaped pressing plate 74.

[0034] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8 and Figure 9 The U-shaped support frame 70 has an arc-shaped support groove 76, and the size of the arc-shaped support groove 76 matches the size of the lower pressure rod 72. The two ends of the lower pressure rod 72 are movably inserted through the arc-shaped support groove 76. An arc-shaped guide rod 77 is fixedly installed on the top of the arc-shaped pressing plate 74. Several guide rings 78 are movably connected to the arc-shaped guide rod 77, and the guide rings 78 are movably abutted against the two ends of the insulator box.

[0035] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8 and Figure 9Several infeed and outfeed rollers 68 are arranged on the side of the U-shaped transfer frame 65 near the sorting frame 10. These rollers are used for horizontal conveying of the insulator boxes. Lifting rollers 35 are movably interwoven between the infeed and outfeed rollers 68, allowing the insulator boxes to smoothly transition between the lifting frame 31 and the U-shaped transfer frame 65. When the insulator box is conveyed onto the U-shaped transfer frame 65, the alignment assembly starts working. The electric telescopic rod 71, which is fixedly installed on the top of the U-shaped support frame 70, is activated, driving the bottom pressing rod 72 to move downward. The two ends of the pressing rod 72 pass through the arc-shaped support groove 76 opened in the U-shaped support frame 70, and move up and down along the arc-shaped support groove 76. The movement is controlled by the moving plate 75 and the arc-shaped pressing plate 76. 4. The bottom movable connection pushes the arc-shaped pressure plate 74 to rotate inward around the support rotating rod 73; the arc-shaped guide rod 77 fixed at the top of the arc-shaped pressure plate 74 swings accordingly, and the guide ring 78 on it moves against the two ends of the insulator box. During the swing, the insulator box is moved to the center position to achieve precise alignment; when the electric telescopic rod 71 retracts, the lower pressure rod 72 moves in the opposite direction along the arc-shaped support groove 76, and pulls the arc-shaped pressure plate 74 to the outside to reset through the moving plate 75. The guide ring 78 disengages from the two ends of the insulator box, preparing for subsequent conveying or transfer, ensuring the consistency of the position of the insulator box on the U-shaped transfer frame 65, ensuring that the insulator box and the classification frame 10 are aligned, and facilitating the precise docking of subsequent processes.

[0036] Working principle: In the storage warehouse, the conveyor frame 11 located at the bottom of the sorting rack 10 horizontally transports the insulator boxes to be stored to the designated lifting position. The multi-layer lifting assembly starts working first. The first motor 25 on the back of the side frame 20 drives one of the fixed gears 21 to rotate clockwise. Since the four fixed gears 21 are arranged in a rectangular layout and connected by a chain 22 with a loop structure, the rotational power of the first motor 25 is synchronously transmitted to all the fixed gears 21, so that the chain 22 runs stably along a fixed clockwise rectangular trajectory.

[0037] The movable block 30 is rigidly connected to one link of the chain 22 via a connecting rod 32 on the side away from the lifting frame 31. Therefore, the movable block 30 moves with the operation of the chain 22, but the movable block 30 does not move freely. Its two sides are fixedly mounted on the T-shaped slider 27. The T-shaped slider 27 is constrained to slide in the T-shaped groove 26 inside the loop-shaped movable plate 24, and the two ends of the loop-shaped movable plate 24 are movably connected to the side frame 20 via a fixing rod 23. When the chain 22 drives the movable block 30 to move, the sliding of the T-shaped slider 27 in the T-shaped groove 26 forces the movable block 30 to move strictly along the inner trajectory of the loop-shaped movable plate 24. At the same time, the loop-shaped movable plate 24 itself will also move back and forth horizontally on the fixing rod 23.

[0038] When the movable block 30 starts to descend from the top position near the sorting rack 10, along the vertical section of the U-shaped movable plate 24, the U-shaped movable plate 24 is located near the sorting rack 10 and remains stationary. At this time, the movable block 30, along with the chain 22, drives the lifting frame 31 to descend synchronously under the constraint of the T-shaped slide 26 and the T-shaped slider 27. The lifting roller 35 on the lifting frame 31 descends and penetrates into the bottom of the conveyor frame 11. When the movable block 30 descends to the bottom, the lifting roller 35 has completely entered under the conveyor frame 11, ready to receive the insulator boxes to be stored.

[0039] The movable block 30 moves to the bottom horizontal section of the U-shaped movable plate 24. With the continuous rotation of the chain 22, it will begin to move horizontally away from the sorting rack 10, driving the lifting frame 31 to move synchronously. At this time, the U-shaped movable plate 24 will move horizontally away from the sorting rack 10 under the limit of the fixed rod 23 until the U-shaped movable plate 24 moves to the farthest point away from the sorting rack 10. The movable block 30 will begin to move vertically upward within the U-shaped movable plate 24 under the constraint of the T-shaped slide 26 and the T-shaped slider 27. The movable block 30 drives the lifting frame 31 to rise synchronously. The lifting roller 35 moves vertically out from under the conveyor frame 11, completely lifting and transferring the insulator box on the conveyor frame 11 to the lifting roller 35, completing the transfer of goods from the conveyor frame 11 to the lifting frame 31.

[0040] As the movable block 30 continues to rise to the top of the U-shaped movable plate 24, the arc-shaped contact rod 33 at the top of the movable block 30 precisely contacts the contactor 34 located at the center of the top of the U-shaped movable plate 24, triggering a signal to start the second motor 51, preparing for subsequent fixed-point swing cleaning. Subsequently, the movable block 30 enters the top horizontal section of the U-shaped movable plate 24 and begins to move horizontally towards the side closer to the sorting rack 10. This horizontal movement generates two key linkages: first, the movable block 30 drives the lifting frame 31 to move synchronously towards the sorting rack 10, causing the insulator box carried by the lifting roller 35 to gradually approach the sorting rack 10; second, the U-shaped movable plate 24, driven by the movable block 30, also moves horizontally towards the side of the sorting rack 10, and the push rod 42 fixedly installed at the top of the U-shaped movable plate 24 moves horizontally accordingly. The push rod 42 extends into the cleaning cylinder 40 to drive the piston plate 41 to move, providing compressed air to push the cleaning components.

[0041] After the movable block 30 moves to the end of the top horizontal section, it begins to descend again along the vertical section of the loop-shaped movable plate 24. The movable block 30 drives the lifting frame 31 to descend synchronously. The lifting roller 35 carries the insulator box and gradually enters the area of ​​the loop-shaped transfer frame 65. When the lifting roller 35 and the inlet and outlet rollers 68 on the loop-shaped transfer frame 65 pass through each other, the insulator box is smoothly transferred from the lifting roller 35 to the inlet and outlet rollers 68. At this point, the insulator box has been successfully transported to the loop-shaped transfer frame 65 at the corresponding height, waiting for subsequent alignment and final storage.

[0042] The movable block 30 continues to descend to the bottom, completing the entire clockwise circular cycle. The movable block 30 then drives the lifting frame 31 to the bottom of the conveyor frame 11, ready for the next pickup and delivery.

[0043] During the process of the lifting frame 31 completing vertical lifting and starting horizontal movement, the cleaning component is triggered to work through the arc-shaped contact rod 33 and contactor 34. The push rod 42, which is fixedly installed on the top of the U-shaped movable plate 24, moves forward as the U-shaped movable plate 24 moves horizontally. Since the top of the push rod 42 is fixedly connected to the piston plate 41 inside the cleaning cylinder 40, the horizontal movement of the push rod 42 directly drives the piston plate 41 to slide inside the cylinder. The end of the cleaning cylinder 40 is provided with an air outlet pipe 43 and an air inlet pipe 44. Both the inlet pipe 44 and the outlet pipe 43 are equipped with one-way valves, which convert the reciprocating motion of the piston plate 41 into directional airflow. When the piston plate 41 moves toward the sorting rack 10, the one-way valve of the outlet pipe 43 opens and the one-way valve of the inlet pipe 44 closes, so as to discharge compressed air. When the piston plate 41 moves in the opposite direction, the one-way valve of the inlet pipe 44 opens and the one-way valve of the outlet pipe 43 closes, so as to draw in external air for replenishment. The inlet pipe 44 is connected to a purification and drying device to ensure that the air entering the cleaning cylinder 40 is dry and pure.

[0044] The discharged compressed air is transported through pipelines to the arc-shaped cleaning seat 45 at the top of the lifting frame 31, and sprayed at high speed from multiple evenly installed cleaning nozzles 46 to clean the upper surface of the insulator box below. The cleaning action is performed just before the insulator box is pushed into the warehouse, ensuring that there is no dust accumulation on its surface and avoiding pollution caused by dust entering the storage area with the box.

[0045] The second motor 51 in the fixed-point swing assembly operates, causing the airflow to form a fan-shaped sweeping coverage. When the second motor 51 starts, its output end drives the drive arm 52 to rotate, and the arc-shaped drive rod 53 at the bottom of the drive arm 52 moves in a circular motion. Since the arc-shaped drive rod 53 is tightly fitted in the arc-shaped rotating groove 56, the circular motion of the drive rod forces the rotating plate 55 to swing back and forth around the rotating rod 54 as the axis. An arc-shaped cleaning seat 45 is fixedly installed at one end of the rotating plate 55. Therefore, the arc-shaped cleaning seat 45 and the cleaning nozzle 46 on it swing synchronously, forming a dynamic sweeping airflow on the top of the insulator box. The swinging airflow can cover the entire top surface of the box, especially achieving thorough cleaning of hard-to-reach areas such as the corners and grooves of the box. The cleaning nozzle 46 swings back and forth with the arc-shaped cleaning seat 45, and the airflow trajectory unfolds in a fan shape, ensuring that every inch of surface dust is blown away, providing a clean guarantee for subsequent storage.

[0046] After the lifting frame 31 transports the insulator box above the loop transfer frame 65, the alignment component is activated to perform the final position correction, ensuring that the box enters the sorting rack 10 for storage in the correct orientation.

[0047] First, a height alignment is performed, adjusting the U-shaped transfer frame 65 to be level with the shelf of the sorting rack 10. Inside the lifting frame 60 on the other side of the side frame 20, the servo motor 61 drives the screw 62 to rotate. Since the lifting block 63 is threadedly connected to the screw 62 and constrained by the limiting rod 66, the lifting block 63 converts the rotational motion of the screw 62 into precise linear lifting. The lifting block 63 is fixedly connected to the U-shaped transfer frame 65 through the lifting rod 64, so the U-shaped transfer frame 65 rises and falls accordingly, making the inlet and outlet rollers 68 on it strictly aligned with the height of the target shelf of the sorting rack 10.

[0048] After the height alignment is completed, the horizontal position of the insulator box on the inlet and outlet rollers 68 is corrected. The electric telescopic rod 71 at the top of the U-shaped support frame 70 pushes the pressing rod 72 to move downward along the arc-shaped support groove 76. The two ends of the pressing rod 72 are movably connected to the bottom of the arc-shaped pressing plate 74 through the moving plate 75. Therefore, the pressing action of the pressing rod 72 is converted into the arc-shaped pressing plates 74 on both sides swinging inward around the support rod 73. The top of the arc-shaped pressing plate 74 is fixedly installed with an arc-shaped guide rod 77. Multiple guide rings 78 are movably sleeved on the guide rod. When the arc-shaped pressing plate 74 swings inward, the guide rings 78 first contact the two ends of the insulator box. The guide rings 78 gradually push the box upright so that its axis is strictly aligned with the entrance direction of the 10-layer sorting rack.

[0049] After the position is corrected, the inlet and outlet rollers 68 on the circular transfer frame 65 rotate, smoothly sending the aligned insulator box into the corresponding shelf of the sorting rack 10 for storage. During this process, the lifting rollers 35 and the inlet and outlet rollers 68 on the lifting frame 31 are staggered and interwoven, realizing a smooth transition from the lifting frame 31 to the circular transfer frame 65 and avoiding tilting or jamming of the box.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
