Description

Technical Field

[0001] This utility model relates to the field of shielding door coating technology, and in particular to a coating equipment for shielding doors of nuclear power plants. Background Technology

[0002] In the construction and operation of nuclear power plants, shielding doors play a crucial role, playing an irreplaceable role in preventing radiation leakage, ensuring the safety of nuclear facilities, and maintaining the stability of the surrounding environment.

[0003] Existing shielding door coating technologies mostly employ manual spraying through pipes. However, this method makes it difficult to accurately coat non-planar areas of the shielding door, such as corners and recesses, which can easily lead to uneven coating thickness and affect the protective effect and aesthetics of the shielding door. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a coating equipment for nuclear power plant shielding doors. The first coating can coat a large area of ​​the shielding door's front surface, ensuring basic coating coverage. When the shielding door has uneven surfaces such as protrusions, corners, and depressions, making it difficult for conventional coating to spray evenly, the second coating on the fixed ring can be rotated by rotating the main shaft. This is achieved through a clever transmission structure such as bevel gears, worm gears, and worms, allowing for flexible angle adjustment. This enables precise targeting of areas that are difficult to coat evenly, effectively compensating for the shortcomings of conventional coating and greatly improving the uniformity and integrity of coating on complex-shaped surfaces such as nuclear power plant shielding doors.

[0005] This utility model also provides a coating device for nuclear power plant shielding doors, comprising: a trolley, a connecting rod fixedly connected to the upper surface of the trolley, a connecting frame fixedly connected to the connecting rod, a rotating groove and a first coating on the connecting frame, a main shaft on the connecting rod, a first bevel gear fixedly connected to one end of the main shaft, a second bevel gear externally meshing with the first bevel gear, a driven shaft fixedly connected to the second bevel gear, a worm gear rotatably connected to the driven shaft, a worm externally meshing with the worm gear, a connecting shaft fixedly connected to the worm, a fixed ring fixedly connected to the connecting shaft, and a second coating fixedly connected to the outside of the fixed ring. Through the above device, the cooperation of the bevel gear, worm gear, and worm can drive the second coating on the fixed ring to rotate, achieving flexible angle adjustment, allowing for precise targeting of areas difficult to coat evenly.

[0006] According to the present invention, a coating device for a nuclear power plant shielding door includes three connecting frames, each extending through a connecting rod. This device, with its connecting frames, enables stable support of the shielding door from multiple positions and allows for multi-angle coating operations, enhancing the overall structural stability and coating coverage of the equipment.

[0007] According to the coating equipment for nuclear power plant shielding doors described in this utility model, a paint tank is fixedly connected to the upper surface of the trolley, and a connecting pump is fixedly connected to the top of the paint tank. Through this device, and via the paint tank and the connecting pump, a continuous and stable supply of paint is ensured during the coating process.

[0008] According to the coating equipment for nuclear power plant shielding doors of this utility model, a connecting pipe is fixedly connected to the output end of the connecting pump, and the connecting pipe is fixedly connected to the side surface of the connecting rod. Through this device, a transmission path for the coating material is established from the connecting pump to the coating components via the connecting pipe, ensuring that the coating material can be smoothly delivered to each coating position and achieving precise material supply.

[0009] According to the coating equipment for nuclear power plant shielding doors of this utility model, the rotating groove is located on both sides of the connecting frame, and the first coating is located on the outer side of the rotating groove. This device provides spatial guidance for the rotation of related components via the rotating groove.

[0010] According to the coating equipment for nuclear power plant shielding doors described in this utility model, the other end of the main shaft is located outside the connecting rod, and a throttle handle is fixedly connected to the outer end of the main shaft. Through this device, the throttle handle allows the operator to manually control the rotation of the main shaft, thereby initiating the operation of a series of subsequent transmission mechanisms and achieving flexible adjustment of the coating angle.

[0011] According to the coating equipment for nuclear power plant shielding doors of this utility model, the driven shaft is located inside the connecting rod, and the connecting shaft is located inside the connecting frame. Through this device, the driven shaft and connecting shaft are rationally arranged inside the equipment, effectively transmitting power during transmission without affecting the external structure of the equipment.

[0012] According to the present invention, a coating device for a nuclear power plant shielding door includes a fixing ring located inside a rotating groove, a second coating element rotatably connected inside the rotating groove, and a flexible hose fixedly connected to both the first and second coating elements, the hose being fixedly connected to a connecting pipe. This device provides stable support for the second coating element via the fixing ring, allowing it to rotate flexibly within the rotating groove to accommodate coating of specific areas.

[0013] Beneficial effects

[0014] Compared with existing technologies, this coating equipment for nuclear power plant shielding doors can perform large-area coating on the front of the shielding door through the first coating, ensuring basic coating coverage. When the shielding door has uneven surfaces such as protrusions, corners, and depressions, making it difficult for conventional coating to spray evenly, the equipment can rotate the main shaft and use ingenious transmission structures such as bevel gears, worm gears, and worms to drive the second coating on the fixed ring to rotate. This allows for flexible angle adjustment, enabling precise targeting of areas that are difficult to coat evenly. This effectively compensates for the shortcomings of conventional coating and greatly improves the uniformity and integrity of coating on complex-shaped surfaces such as nuclear power plant shielding doors.
