Position detection device for crystallizer and bending section

The invention relates to a position detection device for a crystallizer and a bending section. The device comprises a handle, a horizontal adjusting screw, a horizontal plate, a numerical value display screen, a gradienter, a guide rail, a transverse clamping plate, a longitudinal clamping plate, a vertical plate, a sliding block, a sliding block protective cover, a sensor mounting support, a displacement sensor and the like. Two parallel transverse clamping plates and two parallel longitudinal clamping plates are arranged on the periphery of the horizontal plate, the distance between the clamping plates is equal to the distance between the oil cylinder guide rails, two clamping bolts are installed on each of the transverse clamping plates and the longitudinal clamping plates, and coarse positioning of the detection device is achieved through the horizontal plate and the clamping plates; meanwhile, the levelness of the horizontal plate can be conveniently adjusted through the horizontal adjusting screw and th
