The invention relates to a barrier-free lifting platform, in particular to a barrier-free self-propelled arm lifting platform protection structure which comprises a bottom plate and two side baffles symmetrically mounted at the top of the bottom plate. Conveying ramps are rotationally arranged on the two sides of the bottom plate. A buffer groove with an opening in the top is formed in the bottom plate, and a control cavity, two horizontal sliding grooves, two rotating grooves with openings in the side faces and two second vertical sliding grooves are further formed in the bottom plate. The two horizontal sliding grooves and the two rotating grooves are located in the two ends of the control cavity correspondingly and communicate with the control cavity. The rotating groove is located in the top of the horizontal sliding groove and communicates with the horizontal sliding groove. The two second vertical sliding grooves are located in the two sides of the buffer groove correspondingly and communicate with the buffer groove. A first supporting plate and a ball screw are arranged in the buffer groove and the second vertical sliding groove correspondingly. According to the structure, after the wheelchair moves to the first supporting plate, the wheelchair can be fixed through a limiting groove formed by sinking of the first supporting plate, meanwhile, the conveying ramp is automatically rotated to be close to the vertical state to form a baffle, and the second-layer protection effect is achieved.
本发明涉及无障碍升降平台,具体涉及无障碍自行臂升降平台用防护结构,包括底板和两个对称安装在底板顶部的侧挡板;底板的两侧均转动设有输送坡道;所述底板内设有顶部开口的缓冲槽,所述底板内还设有控制腔室、两个水平滑槽、两个侧面开口的转动槽以及两个竖直滑槽二;两个所述水平滑槽和两个转动槽分别位于控制腔室的两端并与其连通;所述转动槽位于水平滑槽的顶部并与其连通;两个所述竖直滑槽二分别位于缓冲槽两侧并与其连通;所述缓冲槽和竖直滑槽二内分别设有支撑板一和滚珠丝杆。该结构可以在轮椅移动到支撑板一上后通过支撑板一下沉形成的限位槽来实现对轮椅固定,同时还自动将输送坡道旋转至接近竖直状态形成挡板,起到第二层防护作用。
