本发明涉及一种卷筒润滑装置和具有其的电葫芦起重机,主梁上设置有可滑动的小车,小车上安装有升降电机和电葫芦卷筒,卷筒本体上设有贯穿筒壁的多个润油孔,润油孔与卷筒本体上的绳槽的底端连通,卷筒本体的内壁上焊接有轴向加强筋和布油环,轴向加强筋内设有轴向油槽,布油环内设有与轴向油槽连通的环形布油槽,卷筒本体的中心还固定有储油桶。本申请通过在卷筒本体上设置贯穿筒壁且与绳槽的底端连通的润油孔,润滑油从绳槽底部流向钢丝绳,对钢丝绳润滑可靠;在电磁阀关闭润油管时,润滑油在大气压力的作用下不会自润油孔流出,布油环内的润滑油自然挥发可使得缠绕在卷筒本体上的钢丝绳保持持续润滑,可有效减缓钢丝绳磨损。

    The invention relates to a winding drum lubricating device and an electric hoist crane with the same. A slidable trolley is arranged on a main beam, a lifting motor and an electric hoist winding drum are mounted on the trolley, a plurality of lubricating oil holes penetrating through the drum wall are formed in a winding drum body, the lubricating oil holes are communicated with the bottom end of a rope groove in the winding drum body, axial reinforcing ribs and an oil distribution ring are welded to the inner wall of the winding drum body, axial oil grooves are formed in the axial reinforcing ribs, annular oil distribution grooves communicated with the axial oil grooves are formed in the oil distribution ring, and an oil storage barrel is further fixed to the center of the winding drum body. The lubricating oil holes penetrating through the drum wall and communicating with the bottom end of the rope groove is formed in the winding drum body, lubricating oil flows to a steel wire rope from the bottom of the rope groove, and the steel wire rope is reliably lubricated; when a lubricating oil pipe is closed by an electromagnetic valve, lubricating oil cannot flow out of the lubricating oil holes under the action of atmospheric pressure, the lubricating oil in the oil distribution ring naturally volatilizes to enable the steel wire rope wound on the winding drum body to be continuously lubricated, and abrasion of the steel wire rope can be effectively relieved.
