The invention relates to the technical field of boarding bridges, and discloses a retractable bearing bridge seat of a movable boarding bridge, which comprises a gallery bridge seat, the lower end of the gallery bridge seat is fixedly connected with two bearing seats, the bottoms of the bearing seats are fixedly connected with driving seats, and shock absorption columns are arranged in the driving seats and right opposite to the upper parts of the bearing seats. An elastic ejector rod is arranged on the upper portion of the interior of the shock absorption column, a center beam is arranged in the driving base, and four inclined grooves are oppositely formed in the two sides of the center beam. According to the retractable bearing bridge seat of the movable boarding bridge, the driving seat is pushed through the push rod, the upper end of the supporting rod can move in the inclined groove, then the inclined plane blocks get close to or away from each other, lifting of the moving wheels is achieved, and after the moving wheels are lowered to the ground, the push rod continues to move so that the fixing feet can only be unfolded outwards to be separated from the ground; conversion from a fixed form to a movable form is completed, the fixed feet are freely folded and unfolded, and the bearing bridge seat can freely move and be fixed.
本发明涉及登机桥技术领域,且公开了一种可移动登机桥的收放承重桥座,包括廊桥座,所述廊桥座的下端固定连接有两个承重座,所述承重座的底部固定连接有驱动座,所述驱动座内正对承重座的上部设置有吸震柱,所述吸震柱的内部上方设置有弹性顶杆,所述驱动座的内部设置有中心梁,所述中心梁的两侧相对设置有四个斜向槽。该可移动登机桥的收放承重桥座,通过推杆推动驱动座,可使支杆上端在斜向槽内移动,继而使斜面块相互靠近或远离,实现移动轮的升降,移动轮降低至地面后,推杆继续运动使固定脚只能向外撑开脱离地面,完成从固定形态向移动形态的转换,实现自由收放固定脚,使承重桥座可自由移动和固定。
