The invention relates to engineering machinery, and discloses a rolling wheel assembly of a climbing frame and a tower crane. The rolling wheel assembly of the climbing frame comprises a hinged arm (4), a rolling wheel (3) and a screw rod (6). The rolling wheel (3) is rotatably installed at the first end of the hinged arm (4) and can abut against a standard joint, the hinged arm (4) is rotatably hinged to the climbing frame (2), the screw rod (6) can be in screw joint to the climbing frame (2), the screw rod (6) can abut against the hinged arm (4), and the screw rod (6) can rotate relative to the climbing frame (2) so as to push the hinged arm (4) to rotate around a hinged shaft (9). Through the above technical scheme, the position of the hinged arm is adjusted through the screw rod, the distance between the rolling wheel and a main chord member can be adjusted more accurately, the distance between the rolling wheel and the main chord member is kept within a more accurate range, the adjustable rolling wheel structure can allow low production accuracy, and production cost is reduced.
本发明涉及工程机械,公开了一种爬升架的滚轮组件及塔机,所述爬升架的滚轮组件包括铰接臂(4)、可转动地安装于所述铰接臂(4)的第一端并能够抵压于标准节的滚轮(3)、螺杆(6),所述铰接臂(4)可转动地铰接于爬升架(2),所述螺杆(6)能够螺接于所述爬升架(2),所述螺杆(6)能够抵压于所述铰接臂(4),并且所述螺杆(6)能够相对于所述爬升架(2)转动,以推动所述铰接臂(4)围绕所述铰接轴(9)转动。通过上述技术方案,通过螺杆来调节铰接臂的位置,可以更为准确地调节滚轮与主弦杆的距离,使得滚轮与主弦杆的距离保持在更为精确的范围内,这种可调节的滚轮结构,可以允许较低的生产精度,降低了生产成本。
