Description
Technical Field
The invention belongs to the technical field of captive balloons, and particularly relates to a captive cable take-up and pay-off winch for a captive balloon.
Background
The captive balloon belongs to one of aerostatics, and is an aerostatics which uses buoyancy lifting gas lighter than air to fill the inside of a balloon body and works by means of a captive cable. Captive balloons have been widely used in various fields such as high-altitude surveillance, weather detection, mobile communication, and advertising.
Currently, winches for deploying and retracting captive balloon mooring lines typically comprise a housing, a drive shaft, a drum, and the like, with the drum typically comprising a plurality of rope grooves matching the diameter of the mooring line. When the winding device works, the motor drives the winding drum to rotate, and the winding drum and the mooring rope are in flexible friction transmission, so that the mooring rope and the winding drum are driven to rotate together, and continuous winding and unwinding of the mooring rope are realized.
Usually, the drum is integrally formed and the rope grooves have the same diameter, and the rotation speed of each rope groove is the same. Ideally, the linear speed of the cable is the same for each groove and is consistent with the groove, but in practice, the motion is often complicated by the flexible friction drive and the elastic deformation of the cable. According to the flexible friction transmission theory of belt transmission, the tensile force transmitted by the belt is related to the friction wrap angle and the friction coefficient, and is in logarithmic exponential relation. For the winding drum provided with a plurality of rope grooves, the pulling force of the inlet end and the outlet end of the mooring rope on each rope groove also changes exponentially, and the difference is extremely large. The mooring rope is generally composed of a rubber surface layer, a lightning protection layer, a kevlar layer, a cable, an optical fiber, a filler and the like, and three conditions that often occur in the winding and unwinding process of the mooring rope are briefly described here:
1) Mooring line damage: excessive mooring line loads, above the flexible friction drive limit, will cause the line to slip entirely on the drum grooves, resulting in severe wear causing line damage and other uncontrolled load impacts.
2) Mooring line delamination: when the friction force between the mooring rope and the rope groove is larger than the friction force between the surface layer of the mooring rope and the lightning protection layer or between the lightning protection layer and the Kevlar layer, the surface layer of the mooring rope is delaminated from the lightning protection layer or the Kevlar layer, and the surface layer of the mooring rope is wrinkled, necked and torn.
3) The mooring rope slips: because the multi-rope-groove drum is generally a rigid body with the same diameter, the linear velocity of each rope groove is the same, but the pulling force of the mooring rope on each rope groove is inconsistent, the elastic extension deformation of the mooring rope is also inconsistent, the mooring rope must slide locally on the rope groove in the process of the cable winding and unwinding movement, and particularly, the slipping sound can be obviously heard when the large-load end of the mooring rope just enters the initial circles of rope grooves of the winch drum. Frequent partial slippage of the cable on the rope grooves also accelerates the wear of the mooring cable and reduces the service life of the cable.
At present, only related patent 'a hawser winch reel (CN 104591020A) for tethered balloon lift-off recovery' in China, the device mainly adopts a simple friction ring arranged on a rope groove of the reel, solves the problem of skidding by adjusting the friction coefficient of the friction ring, but has simple structure and is not ideal in the aspects of friction force adjustment, installation, use effect and the like.

Detailed Description
The invention is realized by the following technical scheme.
A mooring cable reel for a captive balloon comprises a bearing box body 1 for supporting, two groups of winding drums 2 for winding and driving the mooring cable, two power driving devices 4 and a transmission device 5 for transmitting the two groups of winding drums, such as a gear set or a synchronous belt.
The double-power driving device 4 and the two groups of driving devices are backup to each other, independent work or cooperative work can be realized, the rotation directions of the winding drums can be switched according to actual use conditions, and the two groups of winding drums 2 are driven by the driving device 5. The form can make two groups of reels as driving reels, independently or multiply improve wrap angle value in flexible friction transmission according to needs, effectively reduce single race transmission load, namely under the same load, reduce the coefficient of friction between mooring hawser 3 and race 21, correspondingly reduce the interlayer frictional force between the surface layer of the mooring hawser and the lightning protection layer, between the lightning protection layer and the Kevlar layer, thereby improving the process performance and reducing the processing cost of the mooring hawser.
As shown in fig. 2, each winding drum 2 is composed of a plurality of independent detachable grooves 21, the number of the grooves can be determined according to actual requirements, and two groups of winding drums 2 can adjust the center distance of the winding drums or stagger the winding drums in the axial direction at a certain distance according to installation space so as to realize spiral winding of the mooring rope 3 on the grooves of the two groups of winding drums 2 and avoid interference in the operation process.
The drum 2 is formed of a plurality of independent sheaves 21, and the individual sheaves 21 are sequentially mounted on a drive shaft 22 and load-transmitted through keys 23. The diameter of the wheel grooves and the number of the wheel grooves are set according to the size of the load, the looseness, load fluctuation and running stability of the mooring cable are considered, and the number of the wheel grooves is generally set to be 5 or more. The diameters of the wheel grooves 21 on the same group of drums can be adjusted according to actual conditions, and generally the diameters are gradually reduced from a large load end to a low load end according to the load of the mooring rope, the reduction amount depends on the size of the load transmitted and the elastic characteristic of the mooring rope 3, and the wheel grooves are used for solving the problem that the local sliding abrasion of the mooring rope 3 is caused by the inconsistent elastic deformation amount generated by different loads of the mooring rope 3 on each wheel groove 21.
As shown in fig. 3, the spool groove 21 used in the present invention is composed of a groove outer ring 211 and a groove inner ring 212. The race inner ring 212 is connected to the drive shaft 22 by a key 23, the race outer ring 211 and the race inner ring 212 are engaged by a taper pin 213, and the magnitude of the load transmitted between the race outer ring 211 and the race inner ring 212 is adjusted and controlled by a spring 214. The wheel groove outer ring 211 compresses the spring 214 through the taper pin 213, when the load transmitted on the wheel groove outer ring 211 is too large and is larger than the preset load of the spring 214, the taper pin 213 and the spring 214 are pressed into the wheel groove inner ring 212 together, at this time, the wheel groove outer ring 211 and the wheel groove inner ring 212 rotate relatively, so that the condition that the mooring cable 3 slips on the wheel groove 21 integrally under the large load state and is severely worn and damaged is avoided, when the transmitted load on the wheel groove outer ring 211 is reduced and is smaller than the preset load of the spring 214, the taper pin 213 is restored to the meshing position of the wheel groove outer ring 211 and the wheel groove inner ring 212 under the elastic force of the spring 214, and the wheel groove outer ring 211 and the wheel groove inner ring 212 are not rotated relatively under the elastic force provided by the spring device, so that normal load transmission is restored.
Referring to fig. 3, the number of taper pins 213 and springs 214 used for load transmission of the race outer 211 and the race inner 212 according to the present invention, the size of the taper pins 213, and the stiffness characteristics of the springs 214 may be set according to the magnitude of the load to be transmitted. The loads that can be transmitted by the single sheave inner ring 211 and the sheave outer ring 212 can be calculated according to the Euler formula of flexible friction transmission, the wrap angle of the flexible friction transmission is pi, and the friction coefficient is a smaller value of the relative friction coefficient of the mooring rope 3 and the sheave groove 21 and the friction coefficient among the layers of the mooring rope 3, so that the overall slippage of the mooring rope 3 on the sheave groove 21 and the damage of wrinkling, necking, peeling and the like caused by the delamination among the layers of the mooring rope 3 are avoided. The taper pin 213 and the spring 214 are limited by the baffle 216, and are convenient to disassemble, assemble, replace and adjust, and the spring adjusting device 215 can finely adjust the range of the compression stroke of the spring to adapt to the actual use environment.
According to the load size and the characteristics of the mooring rope of an actual product, the running state of the mooring rope 3 on the winding drum 2 is optimized through a series of measures of adjusting the driving device 4, the number and the diameter of the wheel grooves 21 of the winch, adjusting the size of the taper pin 213, the physical characteristics of the spring 214, the number of the taper pin 213 and the spring 214 and the like, the whole slipping of the mooring rope on the rope groove under a large load condition, wrinkling or delamination of the surface skin of the mooring rope can be completely avoided, the occurrence of common problems of local slipping of the mooring rope on the rope groove and the like is greatly reduced, and therefore the winding and unwinding safety of the mooring rope and the service life of the mooring rope are effectively improved.
The scope of the present invention is not limited to the above-described embodiments, and it is apparent that those skilled in the art can make various modifications and variations to the present invention without departing from the scope of the present invention.
