Lateral-turning prevention safety device suitable for lying type horizontal loop moving trolley

The utility model discloses a lateral-turning prevention safety device suitable for a lying type horizontal loop moving trolley. The lateral-turning prevention safety device comprises a base and a lateral-turning prevention device. The base is fixedly connected to a frame. The lateral-turning prevention device comprises horizontal wheel sets and turning prevention hooks, and the horizontal wheel sets and the turning prevention hooks are arranged on the base correspondingly and matched with a steel rail oppositely in a clamping mode. According to the lateral-turning prevention safety device, the horizontal wheel sets and the turning prevention hooks are matched, the lateral-turning prevention safety device is arranged on the bottom of the loop moving trolley, the horizontal wheel sets are symmetrically arranged on the inner side/outer side contact surface of the rail, the turning prevention hooks are symmetrically arranged on the outer side/inner side contact surface of the rail, and therefore the loop moving trolley can always be attached to the rail to move and operates stably and reliably, and lateral-turning accidents are avoided. Even if limit lateral inclination force occurs and the loop moving trolley inclines, the turning prevention hooks can hook the steel rail immediately and prevent the loop moving trolley from turning laterally. The lateral-turning prevention safety device is simple in structure, easy and convenient to install and operate, and safe and reliable in operation.
