Abstract
The invention discloses a container spreader with a novel spin lock mechanism. The container spreader comprises a spreader body and a controller which is installed on the spreader body. The spreader body is provided with an expansion bracket structure, a connecting rod assembly and a spin lock oil cylinder. Spin locks are arranged at the two ends of the connecting rod assembly, and the spin lock oil cylinder is installed on the connecting rod assembly. The container spreader further comprises a closed-state sensor, an opened-state sensor and a baffle installed on the connecting rod assembly. When the baffle makes contact with the closed-state sensor, the closed-state sensor sends locking control signals to the controller, and the controller drives the connecting rod assembly through the spin lock oil cylinder so as to drive the spin locks and a container to be locked. When the baffle makes contact with the opened-state sensor, the opened-state sensor sends unlocking control signals to the controller, and the controller drives the connecting rod assembly through the spin lock oil cylinder so as to drive the spin locks and the container to be separated. According to the container spreader with the novel spin lock mechanism, spin lock state detection is adopted for monitoring the spin lock operation state; and through matching of the container detection, the safety problems caused by the disorderly spin lock state are solved, and accordingly complete machine safety is improved.
