[0033] See also Figure 1-5 The utility model provides a technical solution: a low-energy electron accelerator beam moving device, comprising an accelerator moving device base plate 1, wherein lifting screws 2 are fixedly mounted on both left and right sides of the upper surface of the accelerator moving device base plate 1, an irradiation cavity 12 is fixedly mounted on the top ends of the two lifting screws 2, and a water target 13 is fixedly mounted in the horizontal middle position of the lower surface of the irradiation cavity 12;

[0034] The first pulley 6 and the third pulley 16 are rotatably mounted on the left and right sides of the front end of the irradiation chamber 12, and the motor 5 is fixedly mounted on the left side of the lower surface of the irradiation chamber 12. The driving wheel 4 is fixedly mounted on the output shaft of the motor 5.

[0035] Among them, a second pulley 7 is fixedly installed on the lower surface of the irradiation chamber 12 at a position corresponding to the front side of the motor 5;

[0036] A tray 9 is installed on the left side of the irradiation chamber 12 in a sliding manner and is plugged and rolled. A steel wire rope 8 is fixedly installed on the front end of the right side of the tray 9 .

[0037] Furthermore, the end of the wire rope 8 away from the tray 9 passes through the third pulley 16, the driving wheel 4, the second pulley 7 and the outer surface of the first pulley 6 in sequence and is fixedly installed at the front end position of the left side of the tray 9;

[0038] Among them, a wire tensioning buckle 3 is sleeved and installed on the wire rope 8 at a position close to the driving wheel 4.

[0039] Furthermore, anti-collision blocks 15 are fixedly installed at both ends of the longitudinal middle position inside the irradiation cavity 12, and a proximity switch 14 is fixedly installed on the left side of the anti-collision block 15 at the right end inside the irradiation cavity 12.

[0040] Furthermore, rollers 10 are rotatably installed at the four corners of the lower surface of the tray 9, and guide wheels 11 are rotatably installed at the left and right ends of the front and rear sides of the tray 9. The four guide wheels 11 are all in contact with the side walls of the irradiation chamber 12. When using this device, the motor 5 drives the wire rope 8 to pull one side of the tray 9. The rollers 10 are installed at the bottom of the tray 9 to roll, reducing friction, and the tray 9 moves smoothly. Guide wheels 11 are installed on both sides of the tray 9, so that the tray 9 can smoothly transition to the side walls of the irradiation chamber 12 at the moment of starting to prevent jamming and collision. The tray 9 moves to the end and reaches the proximity switch 14. The motor 5 is controlled to rotate forward and reverse according to the signal feedback to make the tray 9 reciprocate, so that the tray 9 moves smoothly and smoothly. During the reciprocating motion, the wire rope 8 has little wear and high durability, and can reciprocate more than 10,000 times, meeting the operating conditions of the irradiation environment under the electron beam.

[0041] Furthermore, rectangular grooves 17 are provided on both the front and rear sides of the left end of the upper surface of the irradiation chamber 12, and rectangular slide grooves 18 are provided on the left and right sides of the two rectangular grooves 17.

[0043] Among them, springs 22 are fixedly installed inside the four rectangular slides 18, and the four springs 22 are fixedly connected to the four rectangular sliders 19 at one end away from the rectangular slides 18. When the tray 9 needs to be disassembled and maintained, the two limit plates 20 are pulled away from each other, so that the limit plates 20 drive the two rectangular sliders 19 to slide inside the two rectangular slides 18, thereby causing the corresponding two springs 22 to contract, and at the same time causing the telescopic end of the telescopic rod 21 to contract, moving the two limit plates 20 to the lowest end of the two rectangular slots 17, thereby causing the tray 9 to break away from the limit of the two limit plates 20, and the tray 9 is taken out for cleaning and maintenance. By setting the telescopic rod 21 and the spring 22, the installation and disassembly of the tray 9 is facilitated while ensuring the stability of the two limit plates 20 when limiting, thereby improving the practicality of the device.

[0044] Working principle: When using this device, the motor 5 drives the wire rope 8 to pull one side of the tray 9. The bottom of the tray 9 is equipped with a roller 10 to roll to reduce friction, and the tray 9 moves smoothly. Guide wheels 11 are installed on both sides of the tray 9 to make a smooth transition between the tray 9 and the side wall of the irradiation chamber 12 at the moment of starting to prevent jamming and collision. The tray 9 moves to the end and reaches the proximity switch 14. According to the signal feedback, the motor 5 is controlled to rotate forward and reverse to make the tray 9 reciprocate, so that the tray 9 moves smoothly and smoothly. During the reciprocating motion, the wire rope 8 has little wear and tear and high durability. It can reciprocate more than 10,000 times, which meets the working conditions of the irradiation environment under the electron beam. When the tray 9 needs to be disassembled and maintained, the two limit plates 20 are pulled away from each other, so that the limit plates 20 drive the two rectangular sliders 19 to slide inside the two rectangular slide grooves 18, thereby causing the corresponding two springs 22 to contract, and at the same time, the telescopic end of the telescopic rod 21 to contract, and the two limit plates 20 are moved to the lowest end of the two rectangular grooves 17, thereby causing the tray 9 to break away from the limit of the two limit plates 20, and the tray 9 is taken out for cleaning and maintenance. By setting the telescopic rod 21 and the spring 22, the installation and disassembly of the tray 9 is facilitated while ensuring the stability of the two limit plates 20 when limiting, thereby improving the practicality of the device.
