The invention discloses a multi-fulcrum electric single-beam suspension crane which comprises two end beams, first sliding grooves are formed in the tops of the two end beams, second sliding grooves are formed in the left sides and the right sides of the first sliding grooves in the end beams, a plurality of first grooves are formed in the left sides and the right sides of the end beams, and L-shaped blocks are slidably connected into the first grooves. The cavity and the second rectangular opening are formed in the rectangular block, the connecting plate and the electric hoist are fixed through the universal joint, the second spring is arranged on the outer side of the connecting plate, damage to a transmission mechanism in the rectangular block caused by shaking of an object is reduced through contraction of the second spring, and the service life is prolonged; meanwhile, an L-shaped block, a first spring, a supporting seat, a first fixing block and a first limiting block are matched for use, so that the situation that the end beams on the two sides shake due to shaking of the main beam, and fixing pieces on the supporting seat are loosened is reduced, potential safety hazards are reduced, and the beneficial effects of being long in service life and high in safety are achieved.

    本发明公开了一种多支点的电动单梁悬挂起重机,包括两个端梁,两个所述端梁顶部均开设有第一滑槽,所述端梁上第一滑槽的左右两侧均开设有第二滑槽,所述端梁的左右两侧均开设有若干个第一凹槽,所述第一凹槽内滑动连接有L形块。本发明通过在矩形块上开设有空腔与第二矩形口,利用万向节固定连接板与电动葫芦,通过在连接板外侧设置有第二弹簧,通过第二弹簧的收缩来减小物体晃动对矩形块内部的传动机构损伤,延长使用寿命,同时还设置L形块、第一弹簧、支撑座、第一固定块、第一限位块的配合使用,来减小主梁晃动引起两侧端梁晃动,导致支撑座上固定件松动,减小安全隐患,具有使用寿命长、安全性高的优点。
