Description

Device for correcting cable arrangement Technical field

This invention relates to the field of tethered aircraft and, in particular, to a device for correcting cable arrangements.

Background technique

After the cable rope (hereinafter referred to as "cable") connecting the mooring system and the tethered balloon is recovered, it is required to be wound around the storage drum by the cable discharging mechanism of the lift-off recovery system for storage. When the cable is being routed, the servo system rotates the trapezoidal thread screw by the power to drive the trapezoidal thread screw to ensure that the reel rotates one turn, and the distance of the cable from the cable reel to realize the orderly movement of the cable on the reel. Thereby achieving the cable discharging function.

However, at present, the working mode of the mooring balloon discharging mechanism is that the PLC records the number of revolutions of the reel through the encoder on the storage drum, and the servo motor and the speed reducer of the cable guiding mechanism of the frequency converter drive the screw to rotate, thereby The winding speed of the reel coincides with the cable pitch. A proximity switch is arranged at both ends of the cable arranging mechanism, and the servo motor is reversing according to a preset left and right stroke when the cable is discharged. Due to external disturbances or internal factors of the system, the moving speed of the reel is deviated. However, the current solution does not have an internal feedback mechanism to adjust the speed of the reel in real time, resulting in a deviation of the cable arrangement on the storage cable. Squeeze, the upper and lower cables are embedded in each other, and the arrangement is not neat. Therefore, the prior art has the following solutions:

1. Increase the size of the storage drum. By increasing the inner diameter and length of the cable drum, the length of the cable wound on each layer of the drum is increased, and the number of the cable layers can be reduced and the number of the cable layers can be reduced when the total length of the cable is constant. However, the disadvantage of this scheme is that the equipment is heavy and takes up space;

2. The cable arranging device is equipped with a hand wheel. When there is a disordered line, the position of the reel can be manually adjusted by the handwheel. However, the disadvantage of this scheme is that it needs to be equipped with a video monitoring device to monitor the cable arrangement and consume more manpower and material resources;

3. Reduce the cable recovery speed. It has been observed that the chaotic phenomenon of the cable mainly occurs near the two ends of the storage drum, so that the recovery speed of the cable when the reel is moved to the vicinity of both ends of the storage cylinder is appropriately reduced, so that the cable recovery is more stable, so as to reduce the misalignment of the cable. The rate makes the cable arrangement more tidy, but the disadvantage of this solution is that it requires longer recovery time and constant speed regulation.

In view of the problems in the related art, no effective solution has been proposed yet.

In addition, the resistance adjusting device 23 further includes: sleeved on the sliding rod 37 and in sliding contact with the electric resistance wire 31, the cable 26 passes through the sliding assembly and drives the sliding assembly to move along the sliding rod 37, wherein the sliding assembly comprises: a sleeve A slider 34 on the slider 37, and a slider 32 and a lifting lug 36 disposed on opposite sides of the slider 34, the cable 26 passes through the lifting lug 36, and the slider 32 is in sliding contact with the electric resistance wire 31. In addition, the resistance adjusting device 23 further includes: a scale bar disposed in parallel with the slide bar 37, the scale bar is marked with a pendulum angle representing the swing amplitude of the cable 26, and the slider 34 is provided with a metal block on a side facing the scale bar. 35. Continuing to refer to FIG. 4, a proximity switch 39 is provided at a position where the angle on the scale bar is zero, and when the cable 26 is deflected and adjusted by the cable correction device 22 to a position where the angle is zero, the metal block 35 and the proximity switch 39 are provided. The position corresponds in a direction perpendicular to the slide bar 37, thereby triggering an opening command of the proximity switch 39 to stop adjusting the speed increase or deceleration of the wire motor. In addition, the resistance adjusting device 23 further includes: two terminals 33 respectively located at one end of the resistance wire 31 and one end of the sliding rod 37, and the two terminals 33 are connected to the circuit board in the cable correcting device 22 through the power line. To output different voltages by adjusting the resistance. In other embodiments, the terminals may be disposed at both ends of the resistance wire and at both ends of the slider. In actual operation, the resistance wire at the same end and the terminal on the slider may be selected to be connected to the circuit board. In addition, during operation, the cable 26 first passes through the reel 24, passes through the circular hole 38 in the lifting lug 36 of the resistance adjusting device 23, and finally reaches the storage drum 21, and the cable 26 and the lifting lug 36 should be maintained. At least 2mm gap. At the same time, in order to ensure a certain width of the gap between the cable 26 and the lifting lug 36, it is necessary to prepare the lifting lugs 36 of different sizes. For example, if the diameter of the cable 26 is 10 mm, the lifting lugs 36 having the inner diameter of the round hole 38 and larger than 14 mm are selected, and the cable 26 is used. For a diameter of 20 mm, a lifting lug 36 having an inner diameter of the round hole 38 greater than 24 mm is used.

In addition, referring to FIG. 2, the wire reel 24 is a right-angled fan shape, and the right-angled fan shape is composed of an arc-shaped edge and a first straight side and a second straight side at right angles, and the first straight side and the wire lead screw are perpendicular to each other. The two straight sides are parallel with the wire screw, and an arc channel is arranged at the arcuate edge of the right angle fan, and the cable 26 passes through the arc channel to enter the wire wheel 24 from the direction parallel to the wire screw, and The wire reel 24 is perpendicular to the direction of the wire screw. At the same time, a plurality of rollers are arranged in the arc channel. The rotation axes of the plurality of rollers are perpendicular to the plane of the right angle fan, and the plurality of rollers are disposed at least at the entrance of the arc channel. At the exit, it is ensured that the cable 26 can enter in parallel with the lead screw 25, and it can also be vertically discharged from the lead screw 25, and the cable correcting device 22 is fixedly disposed at the center of the right-angled sector of the reel 24 by the connecting bracket. .

Further, in the case where the cable pitch is coincident with the winding speed of the storage drum 21, the cable 26 and the storage drum 21 are parallel in cross section, and in the case where the moving speed of the pulley 24 is deviated, the cable The entry point on the storage drum 21 will deviate from the original position, i.e., the cable 26 and the cross section of the storage drum 21 form an angle, and the movement of the cable 26 will cause the lifting lug 36 of the resistance adjusting device 23 to move horizontally. (such as moving from position 1 to position 2 shown in Figure 2) and the slider 32 moving over the resistance wire 31, thereby changing the output resistance of the resistance adjusting device 23, where the sign of the swing angle can be defined as counterclockwise The clockwise direction is negative, so that the swing of the cable 26 in the counterclockwise direction makes the resistance become larger, and the clockwise swing makes the resistance smaller, and the comparison voltage VA changes in accordance with the change of the resistance. Furthermore, the two threshold voltages are set according to the two maximum allowable swing angles of the cable 26. When the cable 26 swing angle is between the two maximum allowable swing angles, the comparison voltage VA is between the two threshold voltages, and Vout1 and Vout2 output a high level; when the cable 26 swing angle is outside the maximum allowable swing angle, The comparison voltage VA is outside the two threshold voltages, and Vout1 or Vout2 outputs a low level. After receiving the signal, the microcontroller controls the cable motor through the frequency converter to increase or decrease the moving speed of the wire wheel 24. The change in speed of the reel 24 causes the swing angle of the cable 26 to change. When the swing angle of the cable 26 returns to zero, the slider 34 moves to the middle of the resistance adjusting device 23, and the proximity switch 39 of the resistance adjusting device 23 detects that it is attached to The metal block 35 on the slider 34 issues a command to cause the cable motor and the speed reducer to follow the rotation of the cable drum 21 to drive the wire screw 25 to rotate, so that the winding speed of the reel and the cable pitch are re-matched. In order to achieve the function of cable modification. In addition, it can be understood that the sign of the swing angle can also be defined as positive clockwise and negative counterclockwise, which is not limited in the present invention.

In addition, the relationship between the change of the swing angle of the cable 26 and the cable is briefly described below: when the swing angle of the cable 26 is zero, it indicates that the winding speed of the cable drum 21 coincides with the cable pitch, and the cable 26 enters the storage cable 21 vertically; The swing angle of the cable 26 changes, indicating that the winding speed of the cable drum 21 does not coincide with the cable pitch, and the cable entry point of the cable 26 on the storage cable 21 deviates from the original position, and the cable pulley 24 moves at a slow or fast speed. When the swing angle of the cable 26 exceeds the maximum allowable swing angle set by the user, the automatic correction function of the cable modification device 22 is triggered to increase or decrease the moving speed of the cable reel 24 and reduce the absolute value of the cable 26 swing angle. And when the cable 26 swings to zero, the speed of the reel 24 is synchronized with the rotation speed of the storage drum 21, so that the cable 26 is neatly arranged on the storage drum 21. At the same time, during the actual operation, the wire reel 24 goes slightly slower, and the direction of the cable 26 on the cable drum when the cable is discharged has a small angle with the radial direction of the cable drum, as discussed above. Simplify the actual situation and take an approximation of zero.

In addition, the cable 26 swing angle display can be added. The user pre-sets a cable 26 optimal working angle and two maximum allowable swing angles on the swing angle display, and finds the best working angle of the cable 26 on the scale rod. Position, and then move the proximity switch 39 to this position. Since a swing angle corresponds to the resistance value of the resistance adjusting device 23 and its terminal voltage, and the value of the terminal voltage is measured, it can be converted into a corresponding swing angle (calculated as shown in FIG. 5), and then passed through the swing angle. The display is displayed so that the user can conveniently compare the actual swing angle of the cable 26 with the optimum working angle and the maximum allowable swing angle.

In addition, on the basis of adding the cable 26 swing angle display device, the function of detecting the speed change of the cable reel 24 can also be added (calculated as shown in the related content of FIG. 5), and it can be conveniently found that the speed of each reel 24 is Increase or decrease, which helps users to judge the cable routing situation.

In addition, the cable modification device 22 can be adjusted to accommodate the large swing angle of the cable 26. In general, the device correction function is triggered when the cable 26 swing angle exceeds the maximum allowable swing angle. However, in some cases, the positional relationship between the cable drum and the reel 24 is changed, and the working angle of the cable 26 is relatively large. At this time, the two threshold voltages can be changed by adjusting the third resistor R3 and the fourth resistor R4, and the two threshold voltages are changed. The cable 26 swing condition that triggers the device correction function allows the cable modification device 22 to accommodate the large swing angle operation requirements of the cable 26 in this situation.

In addition, relays can be connected to the outputs of the two comparators to control different alarm circuits. When the output is low, the relay is closed, and when the output is high, the relay is turned off. When the cable 26 swing angle exceeds the maximum allowable swing angle, there is always a comparator output that is low, and a comparator output that is high. At this point, there is always a bell circuit that is on and the alarm sounds. In addition, different alarm bells can be set to judge whether the speed of the reel 24 is too fast or too slow by different alarm sounds.

Further, as shown in FIG. 5, the resistance of the resistance adjusting device 23 is Rp, the total resistance of the resistance adjusting device 23 is R, the voltage across the resistance adjusting device 23 is V _A , and the current flowing through the resistance adjusting device 23 is I. The total length of the resistance wire 31 of the resistance adjusting device 23 is L, the swing angle of the cable 26 is α, the vertical distance of the cable take-up point 24 to the resistance adjusting device 23 is d, and the resistance of the first resistor R1 is R. _{1. If the} input voltage is V _in , then there are:

V _in =I·(R ₁ +R _p )

V _A =IR _P

Combining the above formula with the swing angle formula, the formula of the swing angle is as follows:

Since the input voltage V _in, the resistance of the first resistor R1, the resistance adjusting means 23 is the total resistance R, the total length of the resistance adjusting means 23 of the resistance wire 31 is L, the cable wheel 24 to the point of resistance adjusting means rope 23 The vertical distance d is known, so that as long as the voltage across the resistance adjusting device 23 is measured, that is, the voltage V _A is compared, the swing angle of the cable 26 can be calculated from the swing angle formula.

In addition, the best working angle and the maximum allowable swing angle can be obtained, specifically:

The optimum working angle is θ, the radius of the cable 26 is r, and the vertical distance from the cable exit point of the cable reel 24 to the cable entry point of the storage cable 21 is D. Assuming that the cable 26 is not allowed to deviate from the half of the rope position on the storage drum 21, the cable 26 swing angle should be between the two maximum allowable swing angles.
