The force situation analysis diagram of the existing rack traction device is shown in Figure 4a: the front rack box is only equipped with a front trolley, and the rack is set at the bottom of the rack box. Therefore, in addition to setting support wheels, it is also necessary to set pressure wheels on the top of the bracket. , The weight of the front rack box is borne by the front trolley, support wheel and pressure wheel. The maximum span between the fixed support wheel and the front trolley reaches 20 meters, so the front rack box will generate considerable bending stress under the action of its own weight, the coke tank and the gravity of the trolley; The rack box also produces bending stress, so the stress state of the front rack box and the rear end rack box is not ideal. High requirements are put forward for the strength and stiffness of the rack box, resulting in the shape and shape of the rack box. The large structural size leads to an increase in the weight of the equipment. In practical applications, the total weight of the rack box alone is as high as 20 tons. Similarly, the upward support reaction force of the support reaches 30 tons, which also puts forward higher requirements for equipment and foundation. Since the front-end trolley is moving at any time, the distance between the supporting wheel and the moving front-end trolley is constantly changing, and the load on the rack box is always changing during reciprocating motion, and the load on the rack box is an alternating load.
