The invention belongs to the field of aircraft rescue devices, and relates to a sling spacing adjusting structure for a lifting beam, which comprises an auxiliary lifting beam, a sliding connection plate and a pulley block, the sliding connection plate is horizontally mounted at the bottom of the auxiliary lifting beam, the sling spacing adjusting structure is characterized by further comprising a sliding seat, adjusting teeth are arranged on the end faces of the left end and the right end of the sliding connection plate, and the sliding seat is provided with a sliding groove. A groove between every two adjusting teeth forms a limiting groove; a sliding seat is installed on the sliding connection plate in a sliding mode, the sliding seat is fixed through a screw limited in the limiting groove, and the pulley block is installed below the sliding seat. Each sling is designed to be of a fixed structure with the adjustable interval, the bearing area can be conveniently adjusted according to different machine types, and the bearing reliability is further guaranteed. And the distance is fixed, so that the operation of manually assisting in adjusting the distance during hoisting is omitted.
本发明属于飞机救援装置领域,涉及一种用于吊梁的吊带间距调节结构,包括副吊梁、滑接板及滑轮组,在所述副吊梁的底部水平安装有滑接板,其特征在于:还包括滑动座,在所述滑接板左右两端的端面上均设有调节齿,两两调节齿之间的凹槽形成限位槽;在滑接板上滑动安装有滑动座,该滑动座通过限位在限位槽内的螺钉进行固定,所述的滑轮组安装在滑动座的下方。通过将每根吊带设计为间距可调且可固定的结构,可方便根据不同机型调节承托面积,进一步保证承托的可靠性。间距固定,省去了在吊装时,人为辅助调整间距的操作。
