Auxiliary device for replacing cold bed input roller way in bar working procedure

The auxiliary device comprises a bottom plate, a lever mechanism is fixedly installed on the top of the bottom plate, a placing mechanism is fixedly installed on one side of the lever mechanism, a fixing mechanism is fixedly installed on the top face of the bottom plate, and one end of the fixing mechanism is fixedly connected with the lever mechanism. And a limiting mechanism is arranged in the placing mechanism. A balancing weight is fixedly installed on the side wall of the bottom plate, and four trundles are fixedly installed at the bottom of the bottom plate. The ends of the power rods are sleeved with anti-skid sleeves respectively. The input roller way has the advantages of being reasonable in structural design, convenient to replace, and capable of solving the problem that when a ground roller of the input roller way is replaced, due to the narrow operation position, a hydraulic oil pipe and an apron board transmission shaft are arranged at the standing position of an operator, and large safety risks
