[0025] As shown in Figure 2 Two ends of one side surface of the cable guide device 5 are respectively provided with a connecting unit 6 by welding, the connecting unit 6 is a hollow structure, the axial direction of the connecting unit 6 is parallel to the axial direction of the track 3, a pull rope displacement sensor 8 is fixedly arranged on the support on one side of the cable guide device 5, and the pull rope 7 of the pull rope displacement sensor 8 is fixedly arranged on the support on the other side of the cable guide device 5 in sequence after passing through the two connecting units 6 horizontally, so that the pull rope 7 is parallel to the track 3.
[0026] The two connecting units 6 are located on the same side surface (i.e. the same vertical surface) of the cable guide device 5, and it can be understood that the connecting unit 6 can be arranged on the side surface of the cable guide device 5 close to the track 3, or arranged on the side surface of the cable guide device 5 away from the track 3, and the specific limitation is not too much here.
[0027] Further comprising a control mechanism, the control mechanism in the embodiment is an existing PLC controller, the control mechanism is connected with the pull rope displacement sensor 8 and the drum brake of the cable drum 2 through wires, so that when the cable guide device 5 is tilted and derails, the connecting unit 6 can pull the pull rope 7, and then the pull rope 7 pulls the pull rope displacement sensor 8 to generate an inclination signal, and the control mechanism controls the working of the drum brake after receiving the inclination signal, so as to control the working of the cable drum 2 and avoid the damage of the cable caused by being pulled.
[0028] In this embodiment, the connecting unit 6 is a ring structure, such as a steel ring, an iron ring, etc., and in other embodiments, the connecting unit 6 can also be a frame structure of other shapes, such as a square, a rhombus, an oval, etc., as long as it can allow the pull rope 7 to pass through the connecting unit 6 from the middle and can be pulled by the pull rope 7 when the fairlead 5 is tilted, and specific limitations are not made here.

At the same time, after the field rope displacement sensor 8 for detecting the out-of-slot is actuated, the cable drum 2 will also report a drum slack cable fault, and the cart traveling mechanism cannot move, so as to avoid further pulling of the cable. The guide fairlead 5 out-of-slot detection protection function improves the reliability of protection of the cable on the machine and the guide fairlead, and prevents the cable on the machine and the guide fairlead 5 from being damaged again after the guide fairlead is out of the slot.
