The invention discloses an electric pulley block capable of being flexibly operated. The electric pulley block comprises a shell, a worm, a worm wheel meshed with the worm and a rotating shaft. The worm wheel is connected to the rotating shaft, the rotating shaft is provided with a winding drum, and one end of the worm penetrates through the shell. The electric pulley block further comprises an oil injection device which can automatically inject oil between the worm wheel and the worm when the rotating shaft rotates. In the rotation process of the worm wheel, the oil injection device can inject oil between the worm wheel and the worm, so that the worm and the worm wheel are well lubricated, the abrasion between the worm and the worm wheel is greatly reduced, and the electric pulley block can operate flexibly.
本发明公开了一种可灵活操作的电动滑车,包括外壳、蜗杆、与蜗杆啮合的蜗轮、转轴,蜗轮连接在转轴上,转轴上设置有卷筒,蜗杆的一端穿过外壳;还包括在转轴旋转时可自动向蜗轮和蜗杆之间注油的注油装置。本发明中,在蜗轮转动的过程中,注油装置可向蜗轮和蜗杆之间注油,使得蜗杆和蜗轮之间得到了良好的润滑,大大降低了蜗杆和蜗轮之间的磨损,使电动滑车可灵活运行。
