Heat treatment device for chuck type wheel of crane

The utility model relates to a crane accessory production device, in particular to a heat treatment device for a chuck type wheel of a crane. The heat treatment device comprises a frame, wherein a driving shaft, a rotation driving system and a sensor are arranged on the frame, the rotation driving system is in transmission connection with the driving shaft, the sensor is used for heat treatment of the wheel to be treated, a clamp is assembled on the driving shaft and used for clamping the wheel to be treated, and the sensor is arranged on one side of the driving shaft in the radial direction and at the periphery of the clamp. The heat treatment device has the advantages that the clamp is assembled on the driving shaft and used for clamping the wheel to be treated, and the sensor is arranged on one side of the driving shaft in the radial direction and at the periphery of the clamp, so that during heat treatment, the clamp can be used for limiting the movement of the wheel to be treated, and the sensor is fixed relative to the clamp. Therefore, the uniformity and heating depth of heat treatment are facilitated, so that the heat treatment quality is improved.
