The invention discloses a pulley structure of hydraulic lifting equipment for a petroleum drilling machine. The pulley structure comprises a pulley main body, a pulley bracket, a pulley seat, a buffering and guiding mechanism, a first height adjusting mechanism, a second height adjusting mechanism, a supporting bottom plate, a first buffering structure, a second buffering structure and an auxiliary guide wheel structure. By arranging the buffering and guiding mechanism, the first height adjusting mechanism and the second height adjusting mechanism adjust the height of a guide pulley, and the first buffering structure and the second buffering structure can achieve a buffering effect of the guide pulley to a pull rope. The auxiliary guide wheel structure can be abutted to the bottom of the guide pulley through a pushing guide wheel to improve the rotating force of the guide pulley, so that the guide pulley buffers and guides the pull rope passing through the pulley main body to reduce the stress generated when the pull rope works, and the pull rope is buffered, is prevented from being broken, and therefore, the service life of the pull rope is prolonged.

    本发明公开了一种石油钻机用液压提升设备的滑轮结构,包括滑轮主体、滑轮支架、滑轮座、缓冲导向机构、第一高度调节机构、第二高度调节机构、支撑底板、第一缓冲结构、第二缓冲结构和辅助导轮结构,本发明通过设置了缓冲导向机构,由设置的第一高度调节机构和第二高度调节机构课调节导向滑轮的高度,同时设置的第一缓冲结构和第二缓冲结构,可实现导向滑轮对拉绳的缓冲效果,并且设置的辅助导轮结构,可由推送导轮与导向滑轮底部相抵接,提高的导向滑轮的转动力,从而使导向滑轮为滑轮主体上经过的拉绳进行缓冲导向工作,减少拉绳工作时产生的应力,并实现其缓冲,防止拉绳断裂延长其使用寿命。
