Abstract
The utility model discloses a lift compensation chain breakage protection device. Once breaking, a compensation chain can drop due to the action of gravity and fall into a bearing space of a bearing piece to press the bearing piece so as to enable the bearing piece to overcome elastic restoration force of an elastic piece and move downward. The bearing piece can block signal communication between an emitting sensor and a receiving sensor, and once the signal communication is blocked, a controller can detect the abnormal, takes measures instantly and outputs rope clamping signals to a rope clamping device so that the rope clamping device clamps a dragging steel wire rope. Moreover, the controller outputs lift operation stopping signals so that a lift is stopped and protected timely. A lift car is prevented from losing control and sliding downward, and safety accidents are prevented from occurring. The lift compensation chain breakage protection device integrates compensation chain guide and compensation chain protection, can detect and protect compensation chain breakage on any condition, and greatly improves safety of lift operation.
