The invention discloses an electric hoist for a mine, and relates to the technical field of hoisting devices. According to the main points of the technical scheme, the hoist comprises a shell, a driving motor, a reduction gear set, a chain wheel, a chain ring, a lifting hook and a chain ring bag; the shell is provided with an air supply cavity, an air channel and a first one-way valve; a high-pressure airflow generating device is arranged in the air supply cavity, and the high-pressure airflow generating device comprises a cam, a push plate, a second one-way valve and a pressure limiting valve, wherein the cam is provided with a sliding block, and the push plate is provided with a push rod; the shell is provided with a pulse valve; the air channel comprises a main channel and a branch channel; the shell is provided with a filtering cover; the shell is provided with a buffering air bag and a communicating pipeline, wherein the buffering air bag is provided with an air blowing pipe and an air gun; and the shell is provided with a waxing device. According to the hoist, the high-pressure airflow generating device and the pulse valve are arranged, so that dust is not prone to entering the electric hoist; the buffering air bag is arranged, so that the electric hoist is not prone to be impacted and damaged; and the waxing device is arranged, so that the surface of the chain ring is not prone to rusting, and dust is not prone to adhering to the surface of the chain ring.

    本发明公开了一种矿洞用电动葫芦,涉及起重装置技术领域,其技术方案要点是:包括壳体、驱动电机、减速齿轮组、链轮、链环、吊钩、链环袋,壳体设有供风腔、空气通道、单向阀一,供风腔内安装有高压气流发生装置,高压气流发生装置包括凸轮、推板、单向阀二、限压阀,凸轮设有滑块,推板设有推杆,壳体设有脉冲阀,空气通道包括主通道与支道,壳体设有过滤罩,壳体设有缓冲气囊、连通管道,缓冲气囊设有吹气管、气枪,壳体设有上蜡装置。通过设置高压气流发生装置与脉冲阀,使灰尘不易进入电动葫芦内;通过设置缓冲气囊,使本电动葫芦不易受撞击而受损;通过设置上蜡装置,使链环表面不易生锈、不易粘附灰尘。
