Electric door moving machine

Abstract

The invention relates to an electric door moving machine. The electric door moving machine comprises a fixed plate; a sliding frame is movably arranged on the fixed plate; a protective door is movablyarranged below the sliding frame; a sliding mechanism for pushing the protective door to move is arranged on the fixed plate; a rotating mechanism for changing a gap between the protective door and awall body is arranged on the sliding frame; the rotating mechanism comprises a second motor mounted on the sliding frame, a second speed reducer mounted on the second motor, a second gear mounted onthe second speed reducer, and fan-shaped teeth engaged with the second gear; a transmission structure which drives the protective door to rotate simultaneously is arranged at a rotating center of thefan-shaped teeth; a suspension structure used for suspending the protective door is arranged on each of a driving rod and a driven rod; each suspension structure comprises a connecting piece and a suspension rod; one end of one of the connecting pieces is concentric with the rotating center of the fan-shaped teeth; and one of the suspension rods is fixedly connected to one end, far away from the rotating center of the fan-shaped teeth, of the corresponding connecting piece. The electric door moving machine has the effect of facilitating the opening and closing of the protective door.

Description

technical field [0001] The invention relates to the technical field of protective doors, in particular to an electric door sliding machine. Background technique [0002] Protective doors are widely used in nuclear-related process rooms or laboratories such as large-scale nuclear facilities, irradiation processing, radioactive waste treatment, and radioactive source storage. There are often strong gamma rays in these places, which will cause potential radiation impact on personnel, the public and the environment. Therefore, radiation protection doors must be used to shield the gamma rays in the above-mentioned related places. [0003] Anti-radiation doors play a vital role in medical treatment, and the setting of its structure directly affects normal use and anti-radiation effects. The common structure is a translational structure, and the translational structure is divided into ground rails or suspension rails. When the ground rail structure is used, it will be deformed af...

Problems solved by technology

[0005] The above-mentioned existing design scheme has the following defects. There is a concave structure on the track. When the door body needs to be opened, the door body needs to overcome its own gravity before the door body can be removed from the concave structure, which is not convenient for the door body. turn on
