The invention relates to the technical field of lifting devices, and discloses an electric hoist for engineering construction, which comprises a shell, a rotating shaft is connected in the shell, a chain wheel is fixedly connected to the outer side of the rotating shaft, and a chain groove is circumferentially formed in the outer side of the chain wheel. A fixed magnet is arranged on the side, close to a fixed ring, of a chain wheel, the fixed magnet and a movable block in the fixed ring are magnetically attracted to move, and when the chain wheel retracts a transmission chain, the chain wheel rotates to drive the fixed magnet to rotate, so that the movable block rotates in the fixed ring, and meanwhile the movable block rotates. And meanwhile, the movable blocks extrude the inner sides of the extrusion pipes in the fixed rings, so that the movable blocks partition lubricating liquid in the extrusion pipes on the two sides of the movable blocks on the inner sides of the extrusion pipes, and the lubricating liquid in the extrusion pipes on the two sides of the movable blocks is blocked by the movable blocks on the inner sides of the extrusion pipes. Lubricating liquid flowing out through extrusion of the extrusion pipe, close to one side of the liquid outlet pipe, of the movable block is sprayed to the surface of the transmission chain through the opening end of the liquid spraying head.

    本发明涉及起重装置技术领域,且公开了一种用于工程施工的电动葫芦,包括外壳,所述外壳的内部连接有转轴,所述转轴的外侧固定连接有链轮,所述链轮的外侧周向开设有链槽。通过链轮靠近固定环的一侧设置有固定磁铁,令固定磁铁和固定环内部的活动块进行磁性吸引移动,在链轮进行收回传动链时,链轮转动带动固定磁铁转动,使活动块在固定环的内部转动的同时,挤压固定环内部的空气通过通气管向喷气头的开口端吹出,吹动传动链的表面进行清灰,同时,活动块在固定环的内部挤压挤压管的内侧,令活动块在挤压管的内侧对活动块两侧的挤压管内的润滑液进行隔断,使活动块靠近出液管一侧的挤压管被挤压流出的润滑液通过喷液头开口端喷向传动链的表面。
