[0002] In low-energy accelerator applications in sheet metal production lines, such as sheet coating curing, steel strip coating curing, and thin film curing, crosslinking, grafting, and coating, vertical accelerators, due to their vertical electron beam output, can adapt to irradiation materials of varying widths and are widely used. However, different shielding structures need to be designed to meet the irradiation requirements of different materials, and these movable shields need to be frequently opened and closed.

[0003] In existing technologies, when lifting and lowering a heavy lower shield, the lack of a guiding device during movement makes it difficult to ensure its stability and consistency of movement trajectory. Furthermore, the unique structure of the connection between the fixed and moving shields requires extremely high positional accuracy for each opening and closing operation, preventing any displacement. Additionally, traditional lifting devices lack design flexibility and cannot quickly adapt to changes in irradiation width and height required for different materials. Therefore, we propose a lifting device for the moving shield of a low-energy accelerator in a plate material production line. Utility Model Content

At the same time, the special structure of the connection between the fixed shield and the moving shield requires extremely high positional accuracy for each opening and closing, and displacement must not occur. In addition, traditional lifting devices lack flexibility in design and cannot quickly adapt to changes in irradiation width and height required by different materials.

[0025] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0028] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0029] Please see Figure 1-9 This utility model provides a technical solution: a lifting device for a low-energy accelerator moving shield for a plate production line, comprising a frame 1, a moving shield assembly 2, a transmission motor 3, a transmission distribution reducer 4, a rotary reducer 5, a horizontal transmission short shaft 6, a horizontal transmission long shaft 7, a double-output shaft worm gear box 8, a single-output shaft worm gear box 9, a coupling 10, a lifting screw 11, a bearing seat 12, a bearing 13, a copper nut 14, a moving shield connector 15, a copper sleeve 16, and a copper sleeve support seat 17.

[0030] The frame 1 is used to install the entire lifting device and is the foundation and positioning component of the lifting device. It is also used for the installation and fixation of other devices of the accelerator. The movable shielding component 2 is the component that needs to be moved and has electrical control requirements such as moving speed, time, distance and limit. The transmission motor 3 is a variable frequency motor. By changing the motor frequency, the lifting speed of the lifting device is controlled, and the speed control during the movement of the shield is achieved in cooperation with the electrical control system.

[0031] The transmission distribution reducer 4 is used to distribute the power and speed of the motor according to the transmission path and position; the angle reducer 5 adapts to the requirements of path and position in hard transmission; the horizontal transmission short shaft 6 and the horizontal transmission long shaft 7 are used for power transmission in different positions and directions, and their length and layout are determined according to design requirements; the double-output shaft worm gear box 8 and the single-output shaft worm gear box 9 are selected according to the transmission chain requirements and the installation position of the lifting screw 11.

[0032] The coupling 10 is used to connect the motor, reducer and transmission shaft and other transmission components; the lifting screw 11 and the copper nut 14 form a friction transmission pair, which is the key component to realize the movement of the moving shield. The lifting screw 11 has a certain rigidity. The four sets of lifting screws and nuts have the same clearance. The starting height and position are consistent during assembly; the bearing seat 12 and the bearing 13 are used to support the lifting screw; the moving shield connector 15 is connected to the copper nut 14 and moves with the copper nut 14 to drive the moving shield to move; the copper sleeve 16 and the copper sleeve support seat 17 are installed together. The copper sleeve support seat 17 supports the copper sleeve 16. The copper sleeve 16 is used to support the lifting screw 11. The supports at both ends of the screw provide axial and radial support and must be well lubricated.

[0033] Furthermore, when using this device, based on the frame 1, each component is installed sequentially according to the transmission chain layout. First, the bearing housing 12 and bearing 13 are installed in appropriate positions on the frame 1 to support the lifting screw 11. The copper sleeve 16 is installed on the copper sleeve support seat 17, and then the copper sleeve support seat 17 is installed in the corresponding position on the frame 1 so that the copper sleeve 16 supports the other end of the lifting screw 11. The transmission motor 3 is installed on the frame 1 and connected to the transmission distribution reducer 4 through the coupling 10. The transmission distribution reducer 4 distributes power according to the design requirements. The transmission direction is changed by the angle reducer 5, and the power is transmitted to the double-output shaft worm gear box 8 and the single-output shaft worm gear box 9 through the horizontal transmission short shaft 6 and the horizontal transmission long shaft 7.

[0034] Connect the lifting screw 11 to the double-output shaft worm gear box 8 and the single-output shaft worm gear box 9 to ensure that the screw is installed securely. Install the copper nut 14 together with the movable shielding connector 15, and then connect the movable shielding connector 15 to the movable shielding assembly 2 so that the copper nut 14 and the lifting screw 11 cooperate.

[0035] When the accelerator's shielding chamber needs to be opened or closed, the drive motor 3 is started. As a variable frequency motor, the drive motor 3 adjusts the frequency according to the preset speed requirements and outputs power. The power is transmitted sequentially through the transmission distribution reducer 4, the angle reducer 5, the horizontal transmission short shaft 6, and the horizontal transmission long shaft 7 to the double-output shaft worm gear box 8 and the single-output shaft worm gear box 9. The double-output shaft worm gear box 8 and the single-output shaft worm gear box 9 drive the lifting screw 11 to rotate. Since the copper nut 14 is connected to the movable shielding connector 15, and the movable shielding connector 15 is connected to the movable shielding assembly 2, the copper nut 14 moves linearly under the drive of the lifting screw 11, thereby driving the movable shielding assembly 2 to move up and down, realizing the opening or closing operation of the shielding chamber.

[0036] During the movement of the mobile shielding component 2, the stability of the mobile shielding component 2 is ensured because the four sets of lifting screws 11 and copper nuts 14 move in unison and are synchronized in transmission. At the same time, the speed of the transmission motor 3 is monitored and adjusted in real time through the electronic control system to ensure that the mobile shielding component 2 moves at the preset speed, time and distance, and stops moving in time when it reaches the limit position.

[0037] Regularly check the connection of each component to ensure that the coupling 10 is firmly connected and there is no looseness. Check the wear of the lifting screw 11 and the copper nut 14. If the wear is serious, replace them in time to ensure transmission accuracy and smoothness. Lubricate the bearing 13 and the copper sleeve 16 by adding an appropriate amount of lubricating oil to ensure that the support parts at both ends of the screw can work normally and reduce friction and wear. When it is necessary to adapt to different irradiation materials, that is, when the irradiation width or height changes, select the appropriate module combination according to the modular design concept.

[0038] This invention employs a hard transmission method and a single motor drive to ensure the synchronous operation of the four lifting screws, effectively solving the problem of the stability of the moving shield when moving without guidance, and ensuring that the connection between the fixed shield and the moving shield accurately engages each time it is opened and closed, with high positional accuracy.

[0039] The modular design allows the device to quickly adapt to the irradiation requirements of different materials, improving design efficiency and accuracy. At the same time, the extensive use of the same purchased and standard parts reduces the cost of the device and enhances the market competitiveness of the accelerator product. The use of variable frequency motors allows for flexible control of lifting and lowering speeds, and together with the electrical control system, it enables precise control of the shield movement process, meeting the requirements of different processes for shield movement.
