Typically, the total weight of the rotary part of the rotary kiln is up to thousands of tons and the downward force generated during the rotation is up to hundreds of tons. Such a large downward-running force not only generates a radial load along the radial direction of the baffle wheel, but also generates an axial load along the direction of the rotating shaft of the baffle wheel because the contact surface of the baffle wheel and the wheel belt is a conical surface. Thus, the catch wheel bears both radial load and axial load, which are important points and difficulties to be considered in the design of the catch wheel. At present, the internal structure of a catch wheel of the existing hydraulic catch wheel device is complex, one or more bearings are arranged between the catch wheel and a vertical shaft, and the bearings are sleeved on the vertical shaft, cannot bear the dead weight of the catch wheel and the vertical load on the contact surface of the catch wheel and a wheel belt, and can only bear horizontal load; the bottom of the vertical shaft is provided with a disc and a built-in bearing for supporting the weight of the baffle wheel and all the bearings at the upper part and the vertical load on the contact surface of the baffle wheel and the wheel belt, namely the horizontal load and the vertical load of the conventional hydraulic baffle wheel device are independently borne by the bearings on the vertical shaft and the bearings at the bottom of the vertical shaft respectively. There are the following problems:
1) The horizontal load and the vertical load are respectively borne by different bearings, so that the load distribution is unbalanced;
