The support shafts 24 are located between the two inner arc iron plates 22. One end of the support shaft 24 is connected to the front inner arc iron plate 22, and the other end of the support shaft 24 is connected to the rear inner arc iron plate 22. The inner diameter dimension of the arc groove matches the outer arc outer diameter dimension on both sides of the idler wheel. The lower part of the inner arc iron plate 22 is connected to the lifting steel plate 21. The distance between the two inner arc iron plates 22 does not exceed the wheel body length of the idler wheel. The width of the four first bearings 23 is 1 / 3 of the arc of the idler wheel body.

[0027] The first bearings 23 are arranged at the front and rear ends of the support shaft 24, and one end of each bearing is connected to the inner side of the inner arc iron plate 22. A first bearing 23 is provided at each end of the support shaft 24. Through the first bearings 23, the support shaft 24 can rotate clockwise or counterclockwise, thus realizing the rotation of the idler wheel. The idler wheel is supported by the arc-shaped groove of the inner arc iron plate 22, the lifting steel plate 21 and the support shaft 24 to ensure the stability during the installation or disassembly of the idler wheel.
