According to the fairlead 100 provided by the embodiment of the invention, the swing arm 120 is arranged on the fairlead body 110, and one end of the swing arm 120 is rotatably connected with the fairlead body 110 by taking the mounting point 130 as a circle center, so that when a cable is pulled, the swing arm 120 can swing left and right by taking the mounting point 130 as the circle center, and the excessive tension force when the cable is pulled is avoided. By arranging the first position sensor 140, the second position sensor 150 and the third position sensor 160 on the fairlead body 110 uniformly around the mounting point 130, and arranging the first induction scale 171, the second induction scale 173 and the third induction scale 175 on the scale disc 170, the relative position of the first position sensor 140 and the first induction scale 171, the relative position of the second position sensor 150 and the second induction scale 173, and the relative position of the third position sensor 160 and the third induction scale 175 can be sensed, when the fairlead is positioned in the sensing range of the first position sensor 140, the second position sensor 150 or the third position sensor 160, the first signal is respectively output, when the fairlead is out of the sensing range, the second signal is respectively output, because the first position sensor 140, the second position sensor 150 and the third position sensor 160 are respectively electrically connected with the controller, the controller can carry out the code arrangement with the signal received and export the operating condition of corresponding chock 100, avoids appearing the card when using machinery class travel switch simultaneously and dies or damage scheduling problem, and then promotes signal transmission's accuracy and stability.
As shown in fig. 2, when the swing arm 120 deviates from the perpendicular line 122 by 15 ° to 45 ° in the first direction, the first sensing ruler 171 is located within the sensing range of the first position sensor 140, the second sensing ruler 173 is located within the sensing range of the second position sensor 150, and the second sensing ruler 173 is located outside the sensing range of the second position sensor 150.
Specifically, the first direction may be a direction deflected to the left in fig. 2, and the first sensing ruler 171, the second sensing ruler 173 and the third sensing ruler 175 need to have a specific shielding range in order to ensure different positional relationships in different deviation intervals. Since the difference between the first position sensor 140, the second position sensor 150 and the third position sensor 160 is 120 °, for convenience of unity, the effective shielding ranges of the first induction ruler 171, the second induction ruler 173 and the third induction ruler 175 are defined, and the effective shielding ranges of the first induction ruler 171, the second induction ruler 173 and the third induction ruler 175 are also described in an angle form in the present application. For example, the effective shielding range of the first sensing ruler 171 may be set to 60 °, the effective shielding ranges of the second sensing ruler 173 and the third sensing ruler 175 may be set to 43 °, so as to satisfy a specific position form formed when the swing arm 120 deviates from the perpendicular line 122 by 15 ° to 45 ° in the first direction.
As shown in fig. 3, when the swing arm 120 is deviated from the perpendicular line 122 by 15 ° to 45 ° in the second direction (the second direction may be a direction deflected rightward in fig. 3), the first sensing ruler 171 is located outside the sensing range of the first position sensor 140, the second sensing ruler 173 is located outside the sensing range of the second position sensor 150, and the third sensing ruler 175 is located inside the sensing range of the third position sensor 160.
In this way, the combination form of the sensing signals output by the first position sensor 140, the second position sensor 150 and the third position sensor 160 is different from other deviation interval angles, and has uniqueness, so that the working state of the fairlead 100 can be clearly indicated.
As shown in fig. 4, when the swing arm 120 deviates from the perpendicular line 122 by 15 ° in the first direction, the first sensing ruler 171 is located within the sensing range of the first position sensor 140, the second sensing ruler 173 is located outside the sensing range of the second position sensor 150, and the third sensing ruler 175 is located outside the sensing range of the third position sensor 160.
In this way, the sensing signals output by the first position sensor 140, the second position sensor 150 and the third position sensor 160 can be combined into a further combination to satisfy the requirement of indicating the working state of the fairlead 100.
As shown in fig. 5, when the swing arm 120 deviates from the perpendicular line 122 by 15 ° in the second direction, the first sensing ruler 171 is located outside the sensing range of the first position sensor 140, the second sensing ruler 173 is located outside the sensing range of the second position sensor 150, and the third sensing ruler 175 is located outside the sensing range of the third position sensor 160.
In this way, the sensing signals output by the first position sensor 140, the second position sensor 150 and the third position sensor 160 can be combined to form a combination, so as to satisfy the requirement of indicating the working state of the cable guide 100.
As shown in fig. 6, the fairlead 100 further comprises an alarm assembly (not shown in fig. 6) electrically connected to the controller, and a fourth inductive ruler 177 and a fifth inductive ruler 179 provided on the ruler code disc 170, the fourth inductive ruler 177 being located between the first inductive ruler 171 and the second inductive ruler 173, and the fifth inductive ruler 179 being located between the first inductive ruler 171 and the third inductive ruler 175.
Specifically, the second position sensor 150 can sense the relative position of the fourth sensing ruler 177, and the third position sensor 160 can sense the relative position of the fifth sensing ruler 179. When the fourth sensing ruler 177 is located within the sensing range of the second position sensor 150 or the fifth sensing ruler 179 is located within the sensing range of the third position sensor 160, it indicates that the deflection angle of the swing arm 120 is too large and the cable is in an excessively tensioned state, and the controller controls the alarm assembly to respond so as to remind corresponding staff to perform troubleshooting. In addition, the effective shielding sections of the fourth induction ruler 177 and the fifth induction ruler 179 provided in this embodiment may be set to 6 ° to realize the correspondence of the specific positional relationship.
It should be noted that the form of the alarm component in the embodiment of the present invention is not particularly limited, and the alarm component may be an audible and visual alarm to remind the staff of taking measures in time, or may be in other forms as long as the purpose of protecting the cable is achieved, such as alarming and controlling the related devices to brake.

Thus, the sensing signals from the first position sensor 140, the second position sensor 150 and the third position sensor 160 can be combined into a new combination, and when the combination is satisfied, it indicates that the cable is in a left over-tight state, and the controller controls the alarm component to respond and take corresponding measures.
As shown in fig. 7, when the swing arm 120 deviates from the perpendicular line 122 by 45 ° to 50 ° in the second direction, the first sensing ruler 171 is located outside the sensing range of the first position sensor 140, the fourth sensing ruler 177 is located within the sensing range of the second position sensor 150, and the third sensing ruler 175 is located within the sensing range of the third position sensor 160.
Thus, the sensing signals output by the first position sensor 140, the second position sensor 150 and the third position sensor 160 can be combined into another new combination, and when the combination is satisfied, it indicates that the cable is in the right over-tight state, and the controller controls the alarm component to respond and take corresponding measures.
