The invention discloses a chain-jamming-preventing protection electric hoist capable of automatically oiling and lubricating. The chain-jamming-preventing protection electric hoist comprises a machineshell, a chain and a power source which is arranged in the machine shell and used for driving the chain to circularly enter and exit. The machine shell is provided with a chain inlet and a chain outlet which allow the chain to circularly enter and exit. An installation plate is installed on the outer wall of one side of the machine shell and provided with two connecting ends which are connected with a chain-jamming-preventing protection device and an oiling device respectively. The chain-jamming-preventing protection device is located below the machine shell. The chain can enter the chain inlet after smoothly passing through the chain-jamming-preventing protection device in advance. The chain-jamming-preventing protection device is provided with a limiting switch. The oiling device is located on the side portion of the machine shell and connected with an oil conveying pipe. One end, not connected with the oiling device, of the oil conveying pipe is inserted into the chain-jamming-preventing protection device and oils the chain-jamming-preventing protection device, and therefore the chain passing through the chain-jamming-preventing protection device is oiled and lubricated. According to the chain-jamming-preventing protection electric hoist, the chain is oiled, the surface smoothness of a chain ring is improved, and the probability of chain knotting is reduced; and meanwhile,for chain knotting, the chain knotting part is blocked outside the machine shell.

    一种自动加油润滑的防卡链保护电动葫芦,包括机壳、链条以及存在于机壳内并用于驱动链条循环进出的动力源,机壳具有供链条循环进出的进链口和出链口,机壳一侧的外壁安装有安装板,安装板具有两处连接端,分别连接有防卡链保护装置以及加油装置,防卡链保护装置位于机壳下方,其中链条需要预先顺利通过防卡链保护装置后能进入进链口,防卡链保护装置设有限位开关,加油装置位于机壳侧部,并连接输油管,未与加油装置连接的输油管端插入防卡链保护装置并对其进行加油,从而对通过防卡链保护装置的链条进行加油润滑。本发明对链条进行上油,增加链环的表面光滑度,降低链条打结的概率,同时也针对链条打结,将链条打结部分阻挡在机壳外。
