Description

Technical Field

[0001] The utility model relates to a low-position transportation protection device. Background Art

[0002] Medical linear accelerators are internationally advanced radiotherapy devices that provide precise radiotherapy services to patients. The accelerator mainframe is a high-value product, costing tens of millions of RMB, and its operation requires guaranteed safety.

[0003] After the medical electron linear accelerator arrives at the hospital, it cannot be transported to the designated storage area using large crane equipment. It needs to be transported manually using equipment. During this transportation process, due to the complex site conditions, it will be affected by slopes, small operating space, uneven ground and other factors, which brings unpredictable risks to transportation. For this reason, a set of low-level transportation protection devices is designed to reduce the risk of damage to the equipment during transportation.

[0004] Medical electron linear accelerators weigh up to 5 tons, with a high center of gravity skewed toward the treatment bed. The accelerator is narrow from front to back, making it prone to tipping during transport. Therefore, the center of gravity should be kept as low as possible during transportation. The medical electron linear accelerator is 1986mm tall. When using the low-level transport protective fixture, the accelerator is 10mm off the ground. If the floor is level and flat, the accelerator can pass through a doorway with a clear height of 1996mm. Using this fixture not only lowers the center of gravity during transport but also allows it to pass through doorways as high as 2000mm, eliminating the financial losses associated with removing the door.

The height of the medical electron linear accelerator is 1986mm, and the overall height during transportation is 2126mm. If it encounters an old machine room with a door opening lower than 2000mm, it cannot pass smoothly. Utility Model Content
