The invention belongs to the technical field of lifting doors, and discloses a movable side lifting door mechanism which comprises a left lifting assembly and a right lifting assembly which are the same in structure. The left lifting assembly is arranged on the left side of a square cabin door frame and comprises an upper pull rod, a lower pull rod, a stand column, a first movable pull rod and a second movable pull rod. The right lifting assembly is arranged on the right side of the door frame and is symmetrical to the left lifting assembly. The overhead door structure further comprises a steel wire rope transmission assembly which is arranged in the square cabin, connected with the stand columns and used for pulling the stand columns and controlling the stand columns to be folded and unfolded. Under the requirement of the limited space size, the lifting function of the shelter side lifting door is achieved through the connecting rod mechanism, the structure is simple and compact, the occupied space is small, interference with tires of a rear axle of a vehicle body is avoided, and the loading and unloading function that substances in a shelter body are carried to the ground or substances on the ground are carried into the shelter body is achieved.
本发明属于升降门技术领域,公开了一种活动式侧面升降门机构,包括左右两组升降组件,两组升降组件结构相同;所述左升降组件设置在方舱门框左侧,包括上拉杆、下拉杆、立柱、第一活动拉杆和第二活动拉杆;所述右升降组件设置在门框右侧,与左升降组件对称设置;所述升降门结构还包括钢丝绳传动组件,所述钢丝绳传动组件设置在方舱内部与立柱连接,用于牵引立柱,控制立柱的收放。本发明在有限空间尺寸的要求下,采用连杆机构实现方舱侧升降门的升降功能,结构简单,紧凑、占用空间小,不会与车体后桥轮胎发生干涉,满足将舱体内物质搬到地面上或地面上物质运进舱体内的装卸功能。
