The invention discloses a pulley device for an elevator, and relates to the technical field of elevator pulleys. The pulley device for the elevator comprises a wheel body, a detachable positioning ring is arranged on the outer wall of the wheel body in the circumferential direction, the positioning ring is provided with a plurality of grooves formed in the circumferential direction, and a plurality of limiting blocks capable of moving in the radial direction of the wheel body are arranged on the outer wall of the wheel body. The inner wall of the positioning ring is provided with a limiting groove used for being matched with the limiting block, the wheel body is provided with an annular guide groove, a guide ring is arranged in the guide groove, a guide block is arranged on the outer wall of the guide ring, and the guide block is provided with an inclined guide face. The guide face is used for making contact with the limiting block and can drive the limiting block to move outwards in the radial direction so that the limiting block can enter the limiting groove to form a limiting structure. And when the grooves in the outer wall of the pulley are worn and need to be replaced, or steel wire ropes with different outer diameters need to be adapted, modular replacement is facilitated.

    本发明公开了一种电梯用滑轮装置,涉及电梯滑轮技术领域。本发明的电梯用滑轮装置,包括轮体,所述轮体的外壁沿周向设置有可拆卸的定位圈,所述定位圈具有多个沿周向设置的凹槽,所述轮体的外壁设置有多个可沿其径向移动的限位块,所述定位圈的内壁开设有用于与所述限位块配合的限位槽,所述轮体开设有环形的导向槽,所述导向槽内设置有导向环,所述导向环外壁设置有导向块,所述导向块具有倾斜的导向面,所述导向面用于与所述限位块接触并且能够驱动其沿径向向外移动,以使所述限位块进入到所述限位槽内形成限位结构。当滑轮外壁的凹槽出现磨损需要更换时,或需要适配不同外径的钢丝绳时,便于进行模块化更换。
