As shown in fig. 3-8, in some embodiments of the present utility model, the slack rope detection mechanism 60 includes a rope clamping assembly 61, a first trigger 62, a first resilient member 63, and a first trigger switch 64.

The rope clamping assembly 61 is rotatably disposed on the bearing body 35, and the rope clamping assembly 61 is capable of being penetrated by the traction rope 32, and the traction rope 32 can provide a moment to the rope clamping assembly 61 in a tensioning state, so that the rope clamping assembly 61 is in a balanced state.

The first trigger piece 62 is disposed on the carrier body 35 and coaxially disposed with the rope clamping assembly 61, so as to move along with the rope clamping assembly 61. That is, the first triggering piece 62 may drive the rope clamping assembly 61 to synchronously rotate when rotating, or may drive the first triggering piece 62 to synchronously rotate when the rope clamping assembly 61 rotates.

When the traction rope 32 is in a tensioning state, the moment of the traction rope 32 on the rope clamping assembly 61 and the moment of the first elastic piece 63 reach dynamic balance again, the compression spring is in an elastic deformation state, and the compression spring drives the first trigger piece 62 to restore to an initial position, namely, a position where the first trigger switch 64 is not triggered.

When the first trigger switch 64 is a position sensor, the position sensor may be a contact sensor or a proximity sensor, and the position of the first trigger member 62 is detected by the position sensor and converted into an output signal to be fed back to the control system of the lifting device, so as to perform closed-loop control on the driving system of the lifting device, so that the driving device is electrically linked and fed back, and the lifting device is enabled to operate more accurately and have higher safety.

When the position sensor is a touch sensor, the touch sensor may include a travel switch, a two-dimensional matrix position sensor, or the like. The position sensor is provided on the movement path of the first trigger 62, and when the first trigger 62 moves, the position sensor hits the travel switch, and the travel switch slightly contacts the inside, thereby completing the control.
