The invention relates to an endless rope winch steel cable deviation-preventing rope supporting wheel capable of achieving telescopic limiting through extrusion force, and discloses a rope supporting wheel which presses telescopic rods making contact with a steel cable into a telescopic cavity through the extrusion force when the steel cable is placed on a rotating wheel, so that the telescopic rods around the steel cable limit the steel cable. And the left-right sliding amplitude of the steel cables with different thicknesses can be limited, and the steel cables are prevented from sliding off from the cable supporting wheel. The device is characterized in that the device is composed of a supporting shaft, a rolling bearing, a baffle, a rotating wheel, a telescopic rod, a rubber head, a telescopic cavity, a telescopic spring, a limiting block and a communicating groove, a through hole is formed in the middle of the rotating wheel, the supporting shaft is sleeved with the rotating wheel through the through hole, the rotating wheel is of a cylindrical structure, and the diameter of the rotating wheel is gradually increased from the middle to the two ends; baffles are correspondingly arranged at the two ends of the rotating wheel, the baffles are of annular structures, the faces, close to the rotating wheel, of the baffles are sunken inwards to form arc-shaped structures, the rolling bearings are arranged between the baffles and the supporting shaft, multiple sets of telescopic cavities are formed in the rotating wheel in the circumferential direction at equal intervals, and each set of telescopic cavities is composed of multiple telescopic cavities.
本发明利用挤压力伸缩限位的无极绳绞车钢缆防偏托绳轮公开了一种在钢缆放置在转动轮上时,通过挤压力将和钢缆接触的伸缩杆压入伸缩腔内,使得钢缆周围的伸缩杆对钢缆进行限位的托绳轮,能够限制不同粗细的钢缆左右滑动的幅度,避免钢缆从托绳轮上滑落。其特征在于由支撑轴、滚动轴承、挡板、转动轮、伸缩杆、橡胶头、伸缩腔、伸缩弹簧、限位块和连通槽组成,转动轮中部开有贯通孔,转动轮通过贯通孔套置于支撑轴上,转动轮为圆柱型结构,转动轮的直径从中部向两端逐渐增加,转动轮两端相对应置有挡板,挡板为环形结构,挡板靠近转动轮的一面向内凹陷形成弧形结构,滚动轴承置于挡板与支撑轴之间,转动轮上沿周向等距开有多组伸缩腔,一组伸缩腔由多个伸缩腔组成。
