Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of transformer coil production equipment, specifically relating to a transformer coil drying device. Background Technology
[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are the primary coil, secondary coil, and iron core. The coil is one of the most important components of a transformer, and drying and curing the coil is a crucial stage in the transformer manufacturing process. Drying transformer coils typically requires a drying chamber / cabin. Multiple transformer coils are placed on a transport trolley and pushed into the drying chamber. Heating components around the drying chamber facilitate drying. Because the heating process generates a large amount of heat, opening the drying chamber after drying can cause injury to workers due to the high temperature. The trolley must be cooled before being pushed out. This process results in low drying efficiency, low safety, and is detrimental to production. Therefore, a transformer coil drying device is needed to solve these technical problems. Utility Model Content
[0003] To address the aforementioned deficiencies in the existing technology, this utility model provides a transformer coil drying device, comprising a material conveying trolley, a guide rail, and a drying chamber. The drying chamber has an inlet and an outlet at both ends, each with an openable door. The guide rail enters the drying chamber from the inlet and extends from the outlet. The material conveying trolley is equipped with wheels that cooperate with the guide rail. Auxiliary feeding / discharging components are provided at both the inlet and outlet of the drying chamber. These components include a horizontal telescopic rod, a vertical telescopic rod, and a push rod. The fixed end of the horizontal telescopic rod is fixed to the drying chamber, and the telescopic end of the horizontal telescopic rod is fixedly connected to the fixed end of the vertical telescopic rod and corresponds to the inlet or outlet. The telescopic end of the vertical telescopic rod points vertically downwards and is connected to a horizontal rod parallel to the feeding / discharging direction of the drying chamber. The end of the horizontal rod corresponding to the inlet or outlet is fixedly connected to the push rod.
[0004] It should be noted that the material transport trolley moves on the guide rail. When the trolley reaches the entrance of the drying chamber, the entrance opens, the horizontal telescopic rod at the entrance extends, the vertical telescopic rod extends, and the push rod moves to the end of the trolley away from the entrance. Then, the horizontal telescopic rod retracts, and the push rod pushes the trolley into the drying chamber. The entrance closes, the push rod returns to its original position, and the coils on the trolley are dried inside the drying chamber. After drying, the outlet opens, the horizontal telescopic rod at the outlet retracts, and the push rod connected to it extends into the drying chamber from the outlet. Then, the vertical telescopic rod extends, and the push rod inside the drying chamber descends and locks onto the trolley. Finally, the horizontal telescopic rod extends again, and the push rod pulls the trolley out of the drying chamber. This process avoids manually pushing the trolley out of the drying chamber, eliminates the need to wait for the drying chamber to cool down, and does not affect the workers' health. Furthermore, the uncooled drying chamber can be used to dry the next trolley filled with coils, reducing heat waste, improving drying efficiency, and benefiting production.
[0005] Preferably, the horizontal telescopic rod is an electric push rod, a hydraulic cylinder, or a pneumatic cylinder.
[0006] Preferably, the vertical telescopic rod is an electric push rod, a hydraulic cylinder, or a pneumatic cylinder.
[0007] Preferably, the material transport trolley is equipped with push-pull brackets that cooperate with the push rod at both the inlet and outlet ends. The push-pull brackets facilitate the push-pull operation of the material transport trolley by the push rod, making the trolley's entry and exit from the drying chamber more stable and efficient.
[0008] Preferably, the door is an electric sliding door. Electric sliding doors are existing technology, and their specific structure and principle will not be described in detail here.
[0009] Preferably, an exhaust pipe is connected to the top of the drying chamber. This facilitates the discharge of the gas inside the drying chamber after drying for further centralized processing.
[0010] Preferably, the drying chamber is equipped with a heating coil and a fan. The heating coil heats and dissipates heat, and the fan distributes the heat generated by the heating coil evenly within the drying chamber, improving the uniformity of the drying process.
[0011] Working Principle: The material transport trolley moves on the guide rail. When the trolley reaches the inlet of the drying chamber, the inlet opens, the horizontal telescopic rod at the inlet extends, the vertical telescopic rod extends, and the push rod moves to the end of the trolley away from the inlet. Then, the horizontal telescopic rod retracts, and the push rod pushes the trolley into the drying chamber. The inlet closes, the push rod returns to its original position, and the coils on the trolley are dried inside the drying chamber. After drying, the outlet opens, the horizontal telescopic rod at the outlet retracts, and the push rod connected to it extends into the drying chamber from the outlet. Then, the vertical telescopic rod extends, and the push rod inside the drying chamber descends and engages with the push-pull rod of the trolley. Finally, the horizontal telescopic rod extends, and the push rod pulls the trolley out of the drying chamber. This process avoids manually pushing the trolley out of the drying chamber, eliminates the need to wait for the drying chamber to cool down, and does not affect the workers' health. Furthermore, the uncooled drying chamber can be used to dry the next trolley filled with coils, reducing heat waste, improving drying efficiency, and benefiting production.
[0012] This utility model also includes other components that enable the normal operation of a transformer coil drying device, such as control components for an electric sliding door, heating coils, fans, cylinders, hydraulic cylinders, and electric push rods, all of which are conventional technologies in the field. Furthermore, devices or components not limited in this utility model, such as electric sliding doors, heating coils, electric push rods, hydraulic cylinders, cylinders, and fans, all employ conventional technologies and equipment in the field.
[0013] The beneficial effects of this utility model are: it avoids manually pushing the material transport trolley out of the drying chamber, eliminates the need to wait for the drying chamber to cool down, and does not affect the health of workers. At the same time, the uncooled drying chamber can be used to dry the next material transport trolley full of coils, reducing heat waste, improving drying efficiency, and benefiting production.

[0020] Example
[0021] like Figure 1-3 As shown, this utility model provides a transformer coil drying device, including a material conveying trolley 7, a guide rail 10, and a drying chamber 1. The drying chamber 1 has an inlet and an outlet at both ends, and each inlet and outlet has an openable door 11. The guide rail 10 enters the drying chamber 1 from the inlet and extends out from the outlet. The material conveying trolley 7 is equipped with wheels 9 that cooperate with the guide rail 10. The drying chamber 1 has auxiliary feeding and discharging components at both the inlet and outlet. The auxiliary feeding and discharging components include a horizontal telescopic rod 2, a vertical telescopic rod 4, and a push rod 5. The fixed end of the horizontal telescopic rod 2 is fixed to the drying chamber 1, and the telescopic end of the horizontal telescopic rod 2 is fixedly connected to the fixed end of the vertical telescopic rod 4 and corresponds to the inlet or outlet. The telescopic end of the vertical telescopic rod 4 is vertically downward and connected to a horizontal rod. The horizontal rod is parallel to the feeding and discharging direction of the drying chamber 1, and the end of the horizontal rod corresponding to the inlet or outlet is fixedly connected to the push rod 5.
[0022] The material transport trolley 7 moves on the guide rail 10. When the material transport trolley 7 is pushed to the inlet of the drying chamber 1, the inlet opens, the horizontal telescopic rod 2 at the inlet extends, the vertical telescopic rod 4 extends, and the push rod 5 moves to the end of the material transport trolley 7 away from the inlet. Then the horizontal telescopic rod 2 retracts, and the push rod 5 pushes the material transport trolley 7 into the drying chamber 1. The inlet closes, the push rod 5 resets, and the transformer coil 6 on the material transport trolley 7 is dried in the drying chamber 1. After drying, the outlet opens, the horizontal telescopic rod 2 at the outlet retracts, and the push rod 5 connected to it extends from the outlet into the drying chamber 1. Then the vertical telescopic rod 4 extends, and the push rod 5 entering the drying chamber 1 descends and locks onto the material transport trolley 7. Then the horizontal telescopic rod 2 extends, and the push rod 5 pulls the trolley out of the drying chamber 1. The above process avoids manually pushing the material transport trolley 7 out of the drying chamber 1, without waiting for the drying chamber 1 to cool down, which will not affect the health of the workers. At the same time, the uncooled drying chamber 1 can be used to dry the next material transport trolley 7 filled with coils, reducing heat waste, improving drying efficiency, and benefiting production.
[0023] The horizontal telescopic rod 2 is an electric push rod 5, a hydraulic cylinder, or a pneumatic cylinder.
[0024] The vertical telescopic rod 4 is an electric push rod 5, a hydraulic cylinder, or a pneumatic cylinder.
[0025] The material transport trolley 7 is fixed with push-pull frames 8 at both the inlet and outlet ends, which cooperate with the push rod 5. The push-pull frames facilitate the push-pull operation of the material transport trolley 7 by the push rod 5, making the operation of the trolley entering and leaving the drying chamber 1 more stable and efficient.
[0026] The door 11 is an electric sliding door. Electric sliding doors are existing technology, and their specific structure and principle will not be described in detail here.
[0027] The top of the drying chamber 1 is connected to an exhaust pipe 3. This facilitates the discharge of the dried gas from the drying chamber 1 for further centralized processing.
[0028] The drying chamber 1 is equipped with a heating coil and a fan. The heating coil generates heat and dissipates it, while the fan distributes the heat generated by the heating coil evenly throughout the drying chamber 1, thereby improving the uniformity of the drying process.
[0029] The heating coil, electric sliding door, fan, etc. in the above embodiments are all existing technologies. This application does not make any improvements to them, but only utilizes their existing functions. For their specific structure and principle, please refer to the product manual or existing technical information, which are all existing technologies.

Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
