The invention discloses a self-lubricating cooling type electric hoist based on heavy hoisting construction. The self-lubricating cooling type electric hoist based on the heavy hoisting construction comprises a fixed cover, a distribution cavity, a support seat, a filter element, a motor I, a driving gear, a cam, a sleeve, a spring, a piston and a liquid spraying pipe. According to the self-lubricating cooling type electric hoist based on heavy hoisting construction, lubricating liquid can flow into the outer side of a gear through adoption of a reciprocating type piston liquid injection mechanism, the lubricating effect on the gear is achieved, and the stability and smoothness of subsequent movement of the electric hoist are improved. A cam mechanism is arranged at the rear end of the motor, an external driving device is not needed, the cam mechanism can be driven to discharge the lubricating liquid in the movement process of the electric hoist, and self-lubricating is achieved. A guiding circulation structure is used for cooperation, lubricating liquid can be conveniently guided into a lifting rope below along the distribution cavity to lubricate a lifting rope area, and the stability of subsequent lifting is improved. In conclusion, the practicability is improved, and the high application and popularization value is achieved.
本发明公开了一种基于重型起吊施工自润滑降温式电动葫芦,包括固定罩、流通腔、支撑座、滤芯、I电机、主动齿轮、凸轮、套筒、弹簧、活塞、喷液管,该一种基于重型起吊施工自润滑降温式电动葫芦,首先因采用往复活塞注液机构,能够实现润滑液流入至齿轮外侧,实现对齿轮的润滑作用,提高了后续电动葫芦移动的稳定性和顺畅性,其次通过电机后端设置的凸轮机构,无需外部驱动装置,亦可在电动葫芦移动过程中驱动凸轮机构来实现润滑液的排出,继而实现自润滑功能,最后配合导向流通结构,也能够便于润滑液顺着流通腔引导至下方的吊绳中,对吊绳区域进行润滑,提高了后续起吊的稳定性,综上,本发明拓展了实用性,具备较高的推广应用价值。
