[0004] However, the above-mentioned cable is connected with the sector mechanism through the mounting piece, and the structure of the connection between the cable and the mounting piece is relatively simple. During the loading test of the rudder, as the number of tests increases, the cable will be repeatedly stretched and relaxed under the traction of the actuator. This repeated loading will cause fatigue of the materials of the cable and the mounting piece. With the passage of time, the degree of material fatigue will gradually increase, eventually leading to the fracture of the connection between the cable and the mounting piece. At the moment of fracture of the cable, due to the release of the elastic potential energy inside the cable, a reverse elastic recoil force will be generated, causing the cable to retract away from the mounting piece, thereby not only stopping the deflection of the sector and the rudder, affecting the normal test, but also causing the cable to fly out or swing, posing a safety hazard to the surrounding personnel and equipment.

Figure 5 ​As shown, the follower plate 616 is fixedly arranged in front of the rotating shaft 615, and the fixed block 617 coaxial with the rotating shaft 615 is fixedly arranged in front of the follower plate 616, so when the gear 614 is driven to rotate by the meshing of the toothed plate 613, the follower plate 616 and the fixed block 617 can be driven to rotate synchronously with the rotating shaft 615 as the axis, and because the centrifugal groove 620 is formed in the end of the follower plate 616 away from the fixed block 617, the centrifugal plate 619 is slidably arranged in the centrifugal groove 620, the second spring 618 is fixedly arranged between the centrifugal plate 619 and the fixed block 617, the centrifugal plate 619 is initially arranged at one end of the centrifugal groove 620 facing the fixed block 617, and when the fixed block 617 is driven to rotate by the rotating shaft 615, the centrifugal plate 619 can be thrown away from the fixed block 617 in the centrifugal groove 620 by the centrifugal effect of the rotating fixed block 617, and the second spring 618 is stretched, and the mounting block 621 is fixedly arranged at the end of the follower plate 616 away from the fixed block 617, the threaded rod 622 is threadedly arranged on the mounting block 621, and the contact plate 623 is fixedly arranged on the side of the threaded rod 622 facing the centrifugal plate 619, so when the installation piece 3 is uniformly pulled by the steel cable 4, the centrifugal effect of the centrifugal plate 619 by the rotating fixed block 617 is the same, and the centrifugal plate 619 is not thrown far enough to contact the contact plate 623, which can be referred to as Figure 5 As shown, in the absence of an abnormal state, the centrifugal plate 619 can at most be thrown to the position between the initial position of the centrifugal plate 619 and the contact plate 623 without contacting the contact plate 623, and when the steel cable 4 has an abnormal condition (breakage at the connection with the installation piece 3), the elastic potential energy in the steel cable 4 is released, an opposite elastic retraction force is generated to make the steel cable 4 retract away from the installation piece 3, and an instantaneous force is generated to make the sliding plate 602 quickly move in the sliding groove 603, and the push plate 605, the first piston rod 608, the U-shaped piston cylinder 609, the second piston rod 611, the toothed plate 613, and the gear 614 can cooperate to drive the fixed block 617 to rotate and increase the centrifugal effect, so that the centrifugal plate 619 is thrown away synchronously, the centrifugal plate 619 moves a greater distance, and finally contacts the contact plate 623, the contact point 624 arranged on the contact plate 623 is touched, and the contact point 624 is electrically connected with the alarm 625 arranged at the top left end of the fixed frame 5, so when the steel cable 4 has an abnormal condition (breakage at the connection with the installation piece 3), the contact point 624 can be contacted under the centrifugal effect to start the alarm 625 to run and give an abnormal warning to the nearby workers;

[0064] According to Figure 5As shown, the touch plate 623 is installed on the mounting block 621 through the threaded rod 622, and the staff can adjust the distance between the touch plate 623 and the centrifugal plate 619 according to the actual traction speed of the steel cable 4, so as to avoid the situation that the steel cable 4 is in contact with the touch plate 623 in the state of uniform traction due to the too close distance between the touch plate 623 and the centrifugal plate 619, and the situation that the steel cable 4 cannot be in contact with the touch plate 623 when the abnormal situation (fracture at the connection between the mounting part 3) occurs, and the adjustment of the position of the touch plate 623 can be realized by rotating the threaded rod 622 to drive the threaded rod 622 to move on the mounting block 621 in a threaded manner, so as to drive the position of the touch plate 623 to change synchronously, so that the touch plate 623 moves close to or away from the centrifugal plate 619, thereby ensuring that the abnormal early warning prompting mechanism 6 can accurately send the early warning signal when the steel cable 4 appears the abnormal situation, avoiding unnecessary false alarm and missing alarm phenomenon, and improving the accuracy and effectiveness of the early warning;

[0065] In the above process, through the centrifugal effect of the centrifugal plate 619, not only can the alarm 625 be started to contact the contact 624 and prompt the nearby staff when the fracture occurs at the connection between the steel cable 4 and the mounting part 3, but also the abnormal traction speed of the steel cable 4 can be judged when the actuator appears the abnormality and the traction speed of the steel cable 4 deviates from the preset value, so as to start the alarm 625 to prompt the early warning in cooperation with the contact 624;

[0066] The above working process is described in detail in the description of the steel cable traction device 1. Figures 1 to 7 .

[0067] The working process of the emergency feedback processing mechanism 7 is as follows:

[0068] As shown in Figure 1 , Figure 6 and Figure 7As shown, the support frame 701 is fixedly arranged on the right upper end of the fixing frame 5, and a cylinder 702 electrically connected with the contact 624 is fixedly arranged on the support frame 701, so that when the contact 624 is touched by the centrifugal plate 619 to open the alarm 625 to give a warning, the cylinder 702 is also opened to start operation, and the driven plate 703 connected with the output end of the cylinder 702 is recovered to the direction where the cylinder 702 is located (i.e. moves backward), due to the symmetrical rotation connection of the connecting plate 704 on the driven plate 703, and the clamping stop plate 705 is rotationally arranged at the end of the connecting plate 704 away from the driven plate 703, the clamping stop plate 705 is symmetrically arranged outside the steel cable 4, and the U-shaped auxiliary frame 707 is symmetrically arranged at the two ends of the front side of the support frame 701, and the moving grooves 708 are symmetrically formed in the inner walls of the two sides of the U-shaped auxiliary frame 707, and the moving blocks 706 are symmetrically fixedly arranged on the outer walls of the two sides of the clamping stop plate 705, and the moving blocks 706 are slidingly arranged in the moving grooves 708, so that when the driven plate 703 moves backward, the two clamping stop plates 705 are driven to slide on the two U-shaped auxiliary frames 707 in opposite directions (i.e. move to the direction where the steel cable 4 is located), and the moving blocks 706 slide in the moving grooves 708 at the same time to cooperate with the opposite movement of the clamping stop plates 705, and the clamping stop plates 705 after moving can tightly contact the outer surface of the steel cable 4 to clamp the steel cable 4, so that the steel cable 4 stops moving, and the situation that the steel cable 4 flies out or swings due to the elastic retraction and inertial effect of the steel cable 4 is avoided, and the safety hidden danger to the surrounding personnel and equipment is avoided, and the emergency feedback processing of the abnormal state of the steel cable 4 is realized.

[0069] In addition, by locking the state of the broken steel cable 4, the further damage to the fracture surface caused by the continuous movement of the steel cable 4 can be prevented, so that the staff can carefully check the fracture position, fracture form, stress condition before fracture and the like of the steel cable 4 in the state that the steel cable 4 stops moving, and the root cause of the accident is more accurately judged, whether it is the quality problem of the steel cable 4 itself, the abnormal operation of the actuator or other external factors leading to the fracture, which is helpful to take targeted improvement measures to prevent similar accidents from happening again.

[0070] The above working process is described in detail in the working process of the steel cable emergency feedback device. Figures 1 to 7 .
