To solve this problem, there are two existing solutions: the first is to set a plastic ring around the axle pin in the middle of each group of pulleys and fix it on the wheel frame by pins, so as to generate up-down swinging motion to solve the height difference in the vertical direction. The second is to cover a conical plastic ring at two ends of each group of pulleys and fix the plastic ring in the middle of the wheel frame by rivets, and the structure can generate a left-right swinging motion to solve the problem of uneven left-right between the pulleys and the rail. The two schemes compensate unbalance in one direction only, lateral and axial stress generated in different directions is not solved, and the using effect and the service life are not remarkably improved. Therefore, there is a need for improvements to current hanger rail pulleys.
