Fireproof door braking device
The fireproof door braking device comprises a door handle, the middle of the door handle is rotationally connected with a fireproof door, and the first end of the door handle is sequentially connected with a traction piece and a braking rod; a door wrap angle is arranged on the lower portion of the fireproof door, a sleeve is fixedly connected to the door wrap angle, the brake rod penetrates through the sleeve from top to bottom in a sliding mode, an end cover is fixedly arranged on the sleeve in an adjustable mode, a blocking piece is fixedly arranged on the portion, located on the lower portion of the end cover, of the brake rod, an elastic piece is arranged on the portion, between the blocking piece and the end cover, of the brake rod, and the elastic piece is fixedly connected with the brake rod. The two ends of the elastic piece abut against the end cover and the blocking piece respectively. The lower end of the brake rod is connected with an adsorption part which can be adsorbed on a ship deck or the ground; the door handle is rotated downwards so that the brake rod can drive the adsorption piece to be away from a ship deck or the ground. The fireproof door braking device can achieve braking at any opening and closing angle after a door closer is installed on a fireproof door in the ship building process, the state of a cabin door is kept, and people can enter and exit conveniently.
本发明公开了一种防火门制动装置，包括门把手，所述门把手的中部与防火门转动连接，所述门把手的第一端依次连接有牵拉件和制动杆；防火门的下部设有门包角，门包角上固定连接有套筒，所述制动杆由上至下滑动穿过所述套筒，套筒上可调固定设有端盖，所述制动杆上位于所述端盖的下部固定设有挡止件，挡止件与所述端盖之间的制动杆上设有弹性件，所述弹性件的两端分别与所述端盖和所述挡止件抵接；制动杆的下端连接有吸附件，所述吸附件可吸附在船舶甲板或者地面上；向下转动所述门把手可使制动杆带动所述吸附件远离船舶甲板或者地面。本发明的防火门制动装置能实现船舶建造过程中防火门安装闭门器后任意开合角度的制动，保持舱门的状态，方便人员进出。
