The invention discloses safe portal frame hoisting equipment with high stability. The equipment comprises supporting seats, rotating mechanisms, rotating shafts, first bearings, carrying frames, firstbevel gears, moving mechanisms, lead screws, sliding sleeves, second bearings, supporting plates, supporting rods, connecting sleeves, moving plates, second bevel gears and universal wheels. The equipment has the beneficial effects that the carrying frames are arranged in the supporting seats, the rotating shafts rotate to drive the first bevel gears to better rotate, and the small first bevel gears better drive the large second bevel gears to rotate, so that effort is saved during both ascending and descending of the universal wheels; when a portal frame needs to be moved, the universal wheels are stretched out of the supporting seats, so that the portal frame is moved to a destination more conveniently for use; and the universal wheels are contracted into the supporting seats when not in use, so that the universal wheels are not in contact with the ground, the portal frame is not convenient to move, and the stability of the portal frame is improved.

    本发明公开了一种稳定性高的安全性龙门架起重设备,包括支撑座、转动机构、转动轴、第一轴承、放置框、第一锥齿轮、移动机构、丝杆、滑动套、第二轴承、支撑板、支撑杆、连接套、移动板、第二锥齿轮和万向轮。本发明的有益效果是:通过在支撑座的内部设有放置框,转动轴转动带动第一锥齿轮更好的转动,较小的第一锥齿轮更好的带动较大的第二锥齿轮转动,使得万向轮的上升和下降都比较省力,在需要移动龙门架时,将万向轮从支撑座的内部伸出,使得龙门架更加方便的移动到目的地进行使用,在不需要使用万向轮时,将万向轮缩进支撑座的内部,使得万向轮不与地面接触,这样就使得龙门架不便于移动,提高了龙门架的稳定性。
