Abstract
The invention discloses a connection structure, of chains and a transfer platform, which is provided with a cracked chain detection device and is in a stacker crane. Two ends of the transfer platform are respectively provided with a connection through hole, wherein a screw seat with a screw seat through hole is connected below the connection through hole through a limiting bolt in a movable mode. A lifting screw on each of the two lifting chains is arranged in a connection through hole and a screw seat through hole at a corresponding end in a penetrating mode, wherein the lower end of the lifting screw is provided with a nut which is clamped outside the bottom of a screw seat at the corresponding end, and a spring is sleeved on the lifting screw in the screw seat through hole. Two ends of the transfer platform are respectively provided with a signal detection assembly with a signal sensor. When the transfer platform is respectively pulled by the lifting chains, screw seats are abutted against the transfer platform, and two springs are respectively compressed. When the lifting chains crack, the elasticity of a spring at a cracked end can ensure that a screw seat of the end moves downwards along a limiting bolt of the end, the signal of cracking of the chains can be detected by a signal sensor of the end and can be sent out by the signal sensor of the end.
