Width-adjustable auxiliary beam bearing mechanism

The utility model provides a width-adjustable auxiliary beam bearing mechanism. The width-adjustable auxiliary beam bearing mechanism mainly solves the problem that due to the fact that existing auxiliary beams are different in specification, it is difficult to apply universal parts to the auxiliary beams of different specifications. The width-adjustable auxiliary beam bearing mechanism comprises a tank supporting base used for bearing a tank and further comprises a connecting base, adjustable multi-stage fixed connection is adopted between the connecting base and the tank supporting base, and the connecting base is fixedly connected with the auxiliary beams. Due to the fact that adjustable multi-stage fixed connection is additionally adopted, the width-adjustable auxiliary beam bearing mechanism is suitable for the auxiliary beams of different specifications, simple in structure and low in cost.
