During the loading test of the rudder, with the increase of the test times, the cable will be repeatedly stretched and relaxed under the traction of the actuator.

With the passage of time, the degree of fatigue of the materials 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, which poses a safety hazard to the surrounding personnel and equipment.

[0026] The complete use steps and working principle of the above embodiment are as follows: It should be pointed out in advance that, as shown in Figure 1 the right end of the steel cable 4 is fixedly connected with the mounting member 3, and the end of the steel cable 4 away from the mounting member 3 is connected with an actuator which can provide a traction force to the steel cable 4 and drive the mounting member 3 to deflect together with the sector-shaped member 1 and the control surface for loading test, and it should be noted that the above are prior art and will not be described in detail here.

[0027] The working process of the abnormality early warning prompting mechanism 6 is as follows: In the process of the actuator providing a traction force to the steel cable 4 to make the mounting member 3 deflect together with the sector-shaped member 1 and the control surface for loading test, as shown in Figure 1、 Figure 2 And Figure 3 As shown in FIG. 7, a sliding groove 603 is formed on the front side of the fixing frame 5, and a sliding plate 602 is arranged in the sliding groove 603, and a sleeve ring 601 is fixedly arranged at the end of the sliding plate 602 away from the sliding groove 603, and the sleeve ring 601 is fixedly arranged on the outer surface of the steel cable 4. Therefore, when the actuator pulls the steel cable 4, the sleeve ring 601 can be driven to slide synchronously to the left in the sliding groove 603 through the connection with the sleeve ring 601. Because the first spring 604 is symmetrically fixed between the sliding plate 602 and the inner wall of the sliding groove 603, when the sliding plate 602 slides to the left, the first spring 604 connected between the left side of the sliding plate 602 and the sliding groove 603 can be compressed, and the first spring 604 connected between the right side of the sliding plate 602 and the sliding groove 603 can be stretched synchronously. Through the design of the first spring 604, the sliding plate 602 and the sliding groove 603, the movement of the steel cable 4 can be matched to increase the stability of the steel cable 4 when it is pulled and moved; When the sliding plate 602 slides to the left in the sliding groove 603, because the push plate 605 is fixedly arranged on the top of the sliding plate 602, and the fixed ball 606 is arranged on the left side of the push plate 605, and the fixed ball 606 is fixedly arranged on the right side of the first piston rod 608, and the first piston rod 608 is slidably arranged on the upper end of the U-shaped piston cylinder 609, the fixed ball 606 can be pushed to move to the left synchronously through the position design of the push plate 605, and the first piston rod 608 can be pushed to the inside of the U-shaped piston cylinder 609, according to Figure 4 As shown in FIG. 8, the sleeve plate 607 is fixedly arranged on the outer surface of the right end of the first piston rod 608, and the third spring 628 is fixedly arranged between the sleeve plate 607 and the U-shaped piston cylinder 609 and arranged on the outer side of the first piston rod 608. When the first piston rod 608 is pushed to move to the left, the third spring 628 can be squeezed synchronously, according to Figure 3 As shown in FIG. 9, the finger plate 626 is fixedly arranged vertically upward on the outer surface of the sleeve plate 607, the scale mark 627 is arranged on the top of the fixing frame 5, and the tip of the finger plate 626 points to the scale mark 627. Therefore, when the push plate 605 pushes the first piston rod 608, the position of the finger plate 626 can be changed synchronously, and the specific position pointed by the tip of the finger plate 626 can also be changed synchronously. Therefore, during the loading test of the rudder surface, the work personnel can record the deflection angle of the rudder surface according to the specific position of the scale mark 627 pointed by the tip of the finger plate 626; As shown in FIG. 10, Figure 4 And Figure 5As shown, since the second piston rod 611 is arranged to slide through the lower end of the U-shaped piston cylinder 609, and the end of the second piston rod 611 away from the U-shaped piston cylinder 609 is fixedly arranged with an L-shaped sliding frame 612 slidingly connected with the front side wall of the fixed frame 5, and the inside of the U-shaped piston cylinder 609 is in a vacuum state, when the first piston rod 608 is pushed to move towards the inside of the U-shaped piston cylinder 609, the second piston rod 611 can be pushed outwards in the U-shaped piston cylinder 609, and through the rightward movement of the second piston rod 611, the L-shaped sliding frame 612 is driven to slide synchronously on the front side wall of the fixed frame 5, and since the toothed plate 613 is fixedly arranged on the L-shaped sliding frame 612, the rotating shaft 615 is arranged to rotate at the lower end of the front side of the fixed frame 5, and the gear 614 is fixedly arranged on the outer surface of the middle part of the rotating shaft 615 and engagedly connected with the lower surface of the toothed plate 613, when the L-shaped sliding frame 612 moves rightwards, the toothed plate 613 is driven to displace synchronously, and through the engagement between the teeth, the gear 614 is driven to rotate synchronously with the rotating shaft 615 on the front side of the fixed frame 5, according to the Figure 5 As shown, the follow-up plate 616 is fixedly arranged on the front side of the rotating shaft 615, and the fixed block 617 is coaxially arranged on the front side of the follow-up plate 616, so when the toothed plate 613 is engaged to drive the gear 614 to rotate, through the follow-up action of the rotating shaft 615, the follow-up plate 616 and the fixed block 617 are driven to rotate synchronously with the rotating shaft 615 as the axis, and since the centrifugal groove 620 is formed at the end of the front side of the follow-up plate 616 away from the fixed block 617, the centrifugal plate 619 is slidingly arranged in the centrifugal groove 620, and the second spring 618 is fixedly arranged between the centrifugal plate 619 and the fixed block 617, and the centrifugal plate 619 is initially arranged at the end of the centrifugal groove 620 towards the fixed block 617, when the rotating shaft 615 rotates to drive the fixed block 617 to rotate synchronously, through the centrifugal action of the fixed block 617 rotating on the centrifugal plate 619, the centrifugal plate 619 is driven to swing away from the fixed block 617 in the centrifugal groove 620, and the second spring 618 is stretched, and the mounting block 621 is fixedly arranged at the end of the front side of the follow-up plate 616 away from the fixed block 617, and the threaded rod 622 is threadedly arranged in the mounting block 621, and the contact plate 623 is fixedly arranged on the side of the threaded rod 622 towards the centrifugal plate 619, when the steel cable 4 uniformly pulls the mounting member 3, the centrifugal action of the fixed block 617 rotating on the centrifugal plate 619 is the same, so the distance of the centrifugal plate 619 swung away due to the centrifugal action is not enough to support the contact plate 623 to be in contact with the centrifugal plate 619, which can be referred to Figure 5As shown, in the absence of abnormal state, the centrifugal plate 619 can be at most only shaken to the initial position of the centrifugal plate 619 and the touch plate 623 without contacting the touch plate 623, and when the steel cable 4 has an abnormal condition (breakage occurs at the connection with the mounting member 3), the elastic potential energy inside the steel cable 4 is released, a reverse elastic retraction force is generated, the steel cable 4 is pulled back away from the mounting member 3, and an instantaneous force is generated, so that the sliding plate 602 moves quickly in the sliding groove 603, and through the coordinated action of 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, the fixed block 617 is rotated to increase the centrifugal effect, which synchronously increases the shaking effect of the centrifugal plate 619, so that the centrifugal plate 619 moves a greater distance and finally contacts the touch plate 623, and the contact 624 provided on the touch plate 623 touches the alarm 625 provided at the top left end of the fixed frame 5, and the contact 624 is electrically connected with the alarm 625, so that when the steel cable 4 has an abnormal condition (breakage occurs at the connection with the mounting member 3), the contact 624 can be contacted under the centrifugal effect to start the alarm 625 to run and give an abnormal early warning to the nearby workers; According to Figure 5 As shown, the touch plate 623 is installed on the mounting block 621 through the threaded rod 622, and the workers 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 distance between the touch plate 623 and the centrifugal plate 619 is too close to cause the steel cable 4 to contact the touch plate 623 under the condition of uniform speed traction, and the situation that the distance between the touch plate 623 and the centrifugal plate 619 is too far to cause the steel cable 4 to fail to contact the touch plate 623 when the steel cable 4 has an abnormal condition (breakage occurs at the connection with the mounting member 3), and the position of the touch plate 623 can be adjusted by the workers 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 synchronously change the position of the touch plate 623, move the touch plate 623 close to or away from the centrifugal plate 619, and thus ensure that the abnormal early warning mechanism 6 can accurately send a warning signal when the steel cable 4 has an abnormal condition, while avoiding unnecessary false alarms and missed alarms, and improving the accuracy and effectiveness of the warning; In the above process, through the centrifugal effect of the centrifugal plate 619, not only can the contact 624 be contacted to start the alarm 625 to prompt the nearby workers when the steel cable 4 has a breakage at the connection with the mounting member 3, but also can the abnormal traction speed of the steel cable 4 be judged through the centrifugal effect of the centrifugal plate 619 when the actuator has an abnormality to make the traction speed of the steel cable 4 increase and deviate from the preset value, so as to cooperate with the contact 624 to start the alarm 625 to give a warning prompt; The above working process is described in detail in the description of the first embodiment. Figures 1 to 7 .

[0028] The working process of the emergency feedback processing mechanism 7 is as follows: As shown in Figure 1 , Figure 6 and Figure 7 , a support frame 701 is fixedly arranged at the right upper end of the fixing frame 5, and a pneumatic 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 pneumatic cylinder 702 is also opened to start operation, and the driven plate 703 connected with the output end of the pneumatic cylinder 702 is recovered (i.e. moves backward) in the direction where the pneumatic cylinder 702 is located, due to the symmetrical rotation connection of the connecting plates 704 on the driven plate 703, and the rotation arrangement of the clamping plates 705 at the ends of the connecting plates 704 away from the driven plate 703, the symmetrical arrangement of the clamping plates 705 outside the steel cable 4, the symmetrical arrangement of the U-shaped auxiliary frames 707 at the two ends of the front side of the support frame 701, the symmetrical opening of the moving grooves 708 in the inner walls of the two sides of the U-shaped auxiliary frames 707, and the symmetrical fixed arrangement of the moving blocks 706 on the outer walls of the two sides of the clamping plates 705, the sliding arrangement of the moving blocks 706 in the moving grooves 708, so that when the driven plate 703 moves backward, the two clamping plates 705 can slide on the two U-shaped auxiliary frames 707 respectively (i.e. move in the direction where the steel cable 4 is located) through the connection of the connecting plates 704, at this time, the moving blocks 706 slide in the moving grooves 708 synchronously to cooperate with the opposite movement of the clamping plates 705, and the moved clamping plates 705 will tightly contact the outer surface of the steel cable 4 to clamp the steel cable 4, so that the steel cable 4 stops moving, avoiding the situation that the steel cable 4 flies out or swings due to the elastic retraction and inertial effect of the steel cable 4, causing potential safety hazards to the surrounding personnel and equipment, and further realizing the emergency feedback processing of the abnormal state of the steel cable 4; In addition, by locking the state of the broken steel cable 4, it can prevent the steel cable 4 from continuing to move to further damage the fracture surface, 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 further more accurately judge the root cause of the accident, 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; The above working process is described in detail in the following Figures 1 to 7 .
