The invention discloses a safe explosion-proof portal crane. An empty groove is formed in an inner cavity of a portal frame, a power box is slidably connected to an inner cavity of the empty groove, a lifting device is fixedly connected to the bottom of the power box, and a driving mechanism and a lubricating mechanism are arranged in the inner cavity of the power box; the lubricating mechanism comprises an oil tank fixed to an inner cavity of the power box. The invention relates to the technical field of explosion-proof portal cranes. According to the safe anti-explosion portal crane, when a double-rod motor rotates, walking wheels are driven to rotate in roller grooves, lubricating oil in an oil tank permeates to the outer side of the oil tank through a permeation sponge and then smeared to the surfaces of the walking wheels, and when the walking wheels roll, the lubricating oil is evenly smeared to the surfaces of the walking wheels and the surfaces of the rails, so that sparks generated by friction between the walking wheel and the rail in the empty groove during walking can be effectively prevented.

    本发明公开了一种安全防爆门式起重机,所述门式框架的内腔开设有空槽,所述空槽的内腔滑动连接有动力箱,所述动力箱的底部固定连接有起吊装置,所述动力箱的内腔内置有驱动机构和润滑机构,润滑机构包括固定在动力箱内腔的油箱,本发明涉及防爆门式起重机技术领域。该安全防爆门式起重机,双杆电机转动时,带动行走轮在滚轮槽内转动,油箱内的润滑油通过渗透海绵渗透到油箱的外侧,然后涂抹在行走轮的表面,行走轮滚动时将润滑油均匀的涂抹到行走轮和轨道的表面,可以有效防止行走轮行走时在空槽内与轨道摩擦产生火花。
