The invention discloses a stable double-beam cantilever crane. The stable double-beam cantilever crane comprises a crane sliding seat, a guide rail, a sliding mechanism, a sliding block, a sliding rod, a rotating rod, a brush, a reset spring, a telescopic spring and an abutting mechanism. The crane has the beneficial effects that when a crane body works and moves towards one side, under the actionof the abutting mechanism, the sliding rod slides in the sliding block without the action of the reset spring, the rotating rod slides out and then rotates downwards under the action of the telescopic spring, the brush at one end of the rotating rod is inserted into the guide rail to scrape away sundries and dust in the guide rail and is pushed to the outside of one side of the guide rail, when the crane sliding seat slides towards the other side, the crane sliding seat pulls the sliding rod to move and pulls the rotating rod to enter the sliding block, the brush is lifted, the brush on the other side of the crane sliding seat rotates to remove dust in the guide rail, and finally, the sliding block is pulled by the sliding rod to slide towards the other side.
本发明公开了一种稳定型双梁悬臂起重机,包括起重机滑座、导轨、滑动机构、滑块、滑杆、转杆、毛刷、复位弹簧、伸缩弹簧和抵触机构。本发明的有益效果是:重机本体在工作向一侧移动时,在抵触机构作用下,使滑杆摆脱复位弹簧的作用下在滑块内部滑动,转杆滑出后在伸缩弹簧的作用下向下转动,使转杆一端的毛刷插入导轨的内部对导轨内部的杂物灰尘进行刮除,并推至导轨的一侧外部,当起重机滑座向另一侧滑动时,起重机滑座会拉动滑杆移动,并拉动转杆进入滑块内部,使毛刷抬起,起重机滑座另一侧的毛刷则转动对导轨内部清灰,最后滑块由滑杆拉动向另一侧滑动。
