Movable safety ladder
The invention relates to a movable safety ladder which adopts the advantages of A-shaped ladders and platform ladders and makes up for the disadvantages of the A-shaped ladders and the platform ladders. The movable safety ladder comprises: a ladder body (10) having a first frame (20) and a second frame (30) which are spaced apart from each other relative to a hinge axis of an upper portion of the ladder body (10) when the portable safety ladder is unfolded, maintain an A shape, and fully fold around the hinge axis when the portable safety ladder is folded; and an upper safety handrail (40) provided at an upper portion of the ladder main body (10) in a ring shape to prevent a worker standing on a work platform (15) of the ladder main body (10) from falling, in which the upper safety handrail (40) is provided at an upper portion of a pair of support members (50) assembled to rise and fall with respect to the first frame (20) to prevent the worker standing on the work platform (15) of the ladder main body (10) from falling. And the second frame (20) is arranged in a rotatable form so as to be completely folded towards the second frame (30) and be in close contact with the second frame (20) when the portable safety ladder is folded.
本发明涉及一种采用A型梯和平台梯的优点并且弥补其缺点的可移动安全梯。可移动安全梯包括：梯主体(10)，其具有第一框架(20)和第二框架(30)，第一框架和第二框架在便携式安全梯展开时相对于梯主体(10)的上部的铰链轴彼此间隔开，保持A形，并且在便携式安全梯折叠时围绕铰链轴完全折叠；以及上部安全扶手(40)，其以环形设置在梯主体(10)的上部处，以防止站在梯主体(10)的工作平台(15)上的工人坠落，其中，上部安全扶手(40)设置在组装成相对于第一框架(20)升降的一对支撑构件(50)的上部处，并且设置成可旋转的形式以在便携式安全梯折叠时朝向第二框架(30)完全折叠并且与第二框架(20)紧密接触。
