Abstract

The invention discloses a shield protection sliding door which comprises door leaves, a door frame and a driving device for driving the door leaves to move. The driving device comprises a motor driving mechanism and a manual driving mechanism. According to the shield protection sliding door, the manual driving mechanism is provided for preventing accidents and works through chain wheel torque transmitting and a labor-saving structure of a hand wheel, and a chain wheel is directly connected with a motor; and when a manual part is not needed to work, the hand wheel is prevented from rotating, and the hand wheel and a shaft are designed into a detachable mode. According to the shield protection sliding door, through effective combination of motor driving and manual driving, the safety of thesliding door is ensured, and occurrence of the accidents is effectively prevented.

Description

technical field [0001] The invention belongs to the field of medical protection equipment, and in particular relates to a shielding protection sliding door. Background technique [0002] In the prior art, electron linear accelerators are most widely used in radiotherapy, and linear accelerators generally refer to accelerators that use high-frequency electromagnetic fields to accelerate, and at the same time, the trajectory of the accelerated particles is a straight line. Two-photon medical linear accelerator is a large-scale medical equipment used for cancer radiation therapy. It generates X-rays and electron beams to directly irradiate tumors in patients, so as to achieve the purpose of eliminating or reducing tumors. [0003] For electron linear accelerators with energy less than 10 Mev, the shielding of X-rays should be considered; for electron linear accelerators with energy greater than 10 Mev, shielding of neutrons and neutron-captured gamma rays should be considered, ...
