Tipping mechanism having tension compensation function

A tipping mechanism having a tension compensation function comprises a winch, a conveying trolley, a fuel basket and a heavy punch assembly. The fuel basket is rotatably arranged on the conveying trolley by means of a rotating shaft; the rotating shaft is fixed to the fuel basket in an eccentric manner; a steel wire rope is wound according to a winding path capable of pulling the fuel basket to betipped; one end of the steel wire rope is fixed to the winch, and the other end is connected with the heavy punch assembly; an elastic element is provided on the rotating shaft; and one end of the elastic element is fixed to the conveying trolley, and the other end is fixed to the rotating shaft or the fuel basket, so that the elastic force of the elastic element can be changed along with the change of the tipping angle of the fuel basket. According to the tipping mechanism, reduced tension of the steel wire rope in the tipping process of the fuel basket can be effectively compensated, so that the tension of the stee
