Abstract

The invention relates to a ground load-bearing door system which comprises a door comprising an upper end and a lower end, an upper guide device matched with the upper end, a lower guide device matched with the lower end and a door driving device, wherein the lower guide device comprises a door track and a traveling wheel mounted at the lower end, and the door is supported on the door track via the traveling wheel; and the door driving device is used for moving the door so as to close and open the door, and the door track is disconnected when traversing a continuous flat car track for enabling a track flat car to pass through. By adopting the ground load-bearing door system, the ground track of the door has the function of realizing smooth transition with the ground track of the flat car, thereby enabling the traveling wheel of the door to smoothly cross over the ground track of the flat car, preventing interfering with the ground track of the flat car, avoiding a very large support beam and an upright post which are required in the hanging transmission way, and reducing the floor area and the construction cost.

Description

technical field [0001] The invention relates to a heavy-duty door, in particular to a ground load-bearing door system. Background technique [0002] Existing radiation protection doors usually have two kinds of transmission modes: one is the suspension type transmission with upper support, which is mainly used on some radiation protection doors with a smaller ratio; the other is the ground load-bearing track type transmission with lower support, which is mainly used In some relatively heavy radiation protection systems. [0003] Some radiation systems require a ground track flat car. When the ground track flat car needs to enter and exit the radiation protection system, the ground track of the flat car should be arranged under the radiation protection door. In order to avoid ground track conflicts, the protective door usually adopts a suspension transmission system. And when the protective door is thicker, it needs a lot of supporting beams and columns, and the floor area i...
