The invention discloses a scattered base steel rail hoisting anti-falling device which comprises a steel rail buckle (2), the steel rail buckle (2) is in an inverted U shape, two wedges (4) are arranged on the inner side of the steel rail buckle (2), the inner side surfaces of the wedges (4) are matched with a rail web of a steel rail (1), the outer side surfaces of the wedges (4) are matched with the steel rail buckle (2), and bolts (5) are installed on the two sides of the steel rail buckle (2) and used for abutting against the wedges (4). The device is arranged at the position three meters away from the two ends of the steel rail, the steel rail buckle is clamped on the upper portion of the steel rail and connected to a lifting rope of a lifting machine through an upper cable buckle, the wedge is installed in the steel rail, and the wedge is tightly attached to the rail web of the steel rail through a bolt, so that the friction force between the steel rail buckle and the wedge is increased. And the steel rail is prevented from slipping off during vertical hoisting.
本发明公开了一种散铺基地钢轨吊装防脱装置,包括钢轨卡扣(2),钢轨卡扣(2)呈倒U形,钢轨卡扣(2)内侧设有两块楔子(4),楔子(4)的内侧表面和钢轨(1)轨腰配合,外侧表面和钢轨卡扣(2)配合,钢轨卡扣(2)两侧安装螺栓(5)用于顶住楔子(4)。本装置设置有钢轨卡扣和楔子来固定钢轨,在距离钢轨两端端头三米处放置此装置,将钢轨卡扣卡在钢轨上部,通过上部索扣连接在起吊机吊绳上,将楔子安装在其内部使用螺栓将楔子紧密贴合在钢轨轨腰处,使其两者之间摩擦力增大,防止钢轨在竖向吊装时发生滑落。
