Simultaneously, three bullet section of thick bamboo fixed establishment 200 slidable mounting can adjust the mounted position of bullet section of thick bamboo fixed establishment 200 for aircraft weapon stores pylon integration hoist device of this embodiment can adapt to the shell of different models.
In this embodiment, the holding ring 210 includes a left holding ring 211 and a right holding ring 212, and the left holding ring 211 and the right holding ring 212 are both slidably installed below the holding ring mounting seat assembly 220, so that when the left holding ring 211 and the right holding ring 212 are tightly attached, the shell 300 is fixed, and when the shell is launched, the left holding ring 211 and the right holding ring 212 are separated, and after the shell is separated from the fixation, the shell flies towards a target by means of a self-powered device.
It will be appreciated that the power means for driving the clasps 210 to slide is located within the clasping mount assembly 220, and that the clasps 210 are drivingly connected to the power means, which may be a screw-nut mechanism or a hydraulic drive mechanism.
During the process of separating the left holding ring 211 and the right holding ring 212 when the shell is launched, in order to ensure the balance, stability and parallelism of the shell 300, a plurality of hanging ring assemblies 400 are further arranged between the mounting seat 100 and the shell 300. The upper end of the suspension ring assembly 400 is mounted to the mount 100 and the lower end is mounted to the cartridge 300.
Specifically, the hanging ring assembly 400 includes a hanging ring 410 and a mounting block 420, where the hanging ring 410 is hung on the mounting seat 100, and the mounting block 420 is fixedly mounted on the barrel 300. Wherein, the lower end of the hanging ring 410 is fixedly provided with an inner rod 430, the upper end of the mounting block 420 is fixedly provided with an outer rod 440, the inner rod 430 is slidably mounted inside the outer rod 440, and the inner rod 430 and the outer rod are separable.
The upper end of the outer rod 440 is provided with a blind hole 441, and the inner rod 430 is slidably installed in the blind hole 441; the side of the inner rod 430 is provided with a sliding groove 431, a hemispherical steel ball 432 is slidably arranged in the sliding groove 431, a spring 433 is further arranged in the sliding groove 431, one end of the spring 433 abuts against the bottom surface of the sliding groove 431, the other end abuts against the lower end surface of the hemispherical steel ball 432, the inner wall of the blind hole 441 is provided with a plurality of pits 442 arranged in a vertical array, and the shape and the size of the pits 442 are matched with those of the hemispherical steel ball 432.
Through this setting, during the shell launch, left embracing ring 211 and right embracing ring 212 separation in-process, through the auxiliary action of rings subassembly 400, outer pole 440 breaks away from interior pole 430 step by step under shell gravity action, under the direction effect of interior pole 430 to and under the elasticity effect of spring 433, the shell breaks away from in-process can guarantee equilibrium, stability and parallelism.
Specifically, the center of the bottom of the mounting seat 100 is provided with a first mounting groove 101, a hanging rod 102 is mounted in the first mounting groove 101, a plurality of hooks 103 are arranged on the hanging rod 102, and the number of the hooks 103 is equal to that of the hanging ring assemblies 400, and can be more than that of the hanging ring assemblies 400. Thus, the sling assembly 400 is suspended from the hanger 103.
In this embodiment, a pair of connection assemblies 110 are disposed on two sides of the bottom of the mounting base 100, and the cartridge fixing mechanism 200 is detachably mounted on the connection assemblies 110 through the embracing ring mounting base assembly 220.
It can be appreciated that when the conventional bullet fixing mechanism 200 is mounted, the bullet fixing mechanism 200 is fixedly mounted on the mounting base 100 by bolts, and in the whole mounting process, equipment is required to drag the bullet fixing mechanism 200, particularly in the process of assembling each bolt, time and labor are wasted; also, the installation position of the cartridge fixing mechanism 200 cannot be conveniently adjusted.
In this embodiment, the connection assembly 110 includes a rail 111 fixedly mounted on the lower end surface of the mounting seat 100, and a rail groove 112 having a "convex" shape is formed in the rail 111; correspondingly, the upper end surface of the embracing ring mounting seat assembly 220 is fixedly provided with a sliding block 221, and the shape and the size of the sliding block 221 are the same as those of the track groove 112.
Therefore, in the installation process of the bullet barrel fixing mechanism 200, the slider 221 of the bullet barrel fixing mechanism 200 is aligned with the convex-shaped track groove 112, and then the bullet barrel fixing mechanism 200 is pushed in from one side to realize the preliminary installation of the bullet barrel fixing mechanism 200 and the installation seat 100, so that the bullet barrel fixing mechanism 200 is not required to be dragged in the whole installation process, and time and labor are saved. Meanwhile, the provision of the "convex" shaped rail groove 112 allows the degree of freedom of the cartridge fixing mechanism 200 in the up-down and left-right directions to be limited.
In this embodiment, the connection assembly 110 further includes a plurality of positioning teeth 113 disposed on the lower end surface of the mounting seat 100, and the upper end surface of the spring barrel fixing mechanism 200 is fixedly provided with a mating tooth 222, and the shape and size of the mating tooth 222 are matched with those of the positioning teeth 113; the positioning teeth 113 are configured to be elastically retractable to extend from the lower end surface of the mount 100 or retract to the lower end surface of the positioning teeth 113.
Wherein, when the cartridge fixing mechanism 200 is installed, some of the positioning teeth 113 are in a first elastic state, and the rest of the positioning teeth 113 are in a second elastic state; when the cartridge holder mechanism 200 is disassembled, all of the plurality of positioning teeth 113 are in the third resilient state.
Thus, when the cartridge fixing mechanism 200 is pushed in from front to back under the cooperation of the track groove 112 and the slide block 221 during installation, the partial positioning teeth 113 in the first elastic state retract to the lower end surface of the installation seat 100 under the extrusion action of the cooperation teeth 222, and the cartridge fixing mechanism 200 can slide from left to right; when the cartridge fixing mechanism 200 slides to the rightmost mating tooth 222 contacts the positioning tooth 113 in the second elastic state, since the rigidity of the positioning tooth 113 in the second elastic state is greater than that of the positioning tooth 113 in the first elastic state, the positioning tooth 113 in the second elastic state is more difficult to retract into the lower end surface of the mounting seat 100, so that the cartridge fixing mechanism 200 cannot slide any more when sliding to the position, or the thrust required to be applied to the cartridge fixing mechanism 200 increases, and the continuous pushing of the cartridge fixing mechanism 200 is stopped at this time.
Through the arrangement, the elastic tube fixing mechanism 200 is arranged on the mounting seat 100 in a sliding mode, and the elastic tube fixing mechanism 200 is always dragged by no external force, so that time and labor are saved; in addition, the spring barrel fixing mechanism 200 automatically stops when reaching the designated installation position, further time and labor are saved, and the installation position is more accurate. By adjusting the elastic state of the positioning teeth 113 at different positions, the adjustment of the mounting position in the left-right direction is achieved.
Specifically, the positioning teeth 113 are triangular teeth, and include a small inclined plane 1131 and a large inclined plane 1132, wherein the inclination angle of the small inclined plane 1131 is smaller than that of the large inclined plane 1132; moreover, when the cartridge holder 200 is installed, the small inclined surface 1131 is a force-receiving surface; when the cartridge holder 200 is disassembled, the large inclined surface 1132 is a force bearing surface.
Wherein the rigidity of the positioning teeth 113 in the third elastic state is smaller than the rigidity of the positioning teeth 113 in the first elastic state, and the rigidity of the positioning teeth 113 in the first elastic state is smaller than the rigidity of the positioning teeth 113 in the second elastic state.
Thus, under the same elastic condition, when the cartridge fixing mechanism 200 is disassembled, the large inclined surface 1132 of the positioning tooth 113 is a stress surface, and is relatively more difficult to retract. Therefore, the rigidity of the positioning teeth 113 in the third elastic state is adjusted to the minimum state, so that the positioning teeth 113 become relatively easy to retract when the cartridge fixing mechanism 200 is detached.
Through the conversion between the three elastic states of the positioning teeth 113, the installation process of the cartridge fixing mechanism 200 is time-saving and labor-saving, and the cartridge fixing mechanism can automatically stop when reaching the designated installation position by matching with the arrangement of the small inclined surface 1131 and the large inclined surface 1132 of the positioning teeth 113, and the stop position is accurate; in addition, the bullet barrel fixing mechanism 200 cannot be retracted after being positioned at the installation position, so that the installation stability of the bullet barrel fixing mechanism 200 is further ensured. When the elastic tube fixing mechanism 200 is disassembled, the positioning teeth 113 are all adjusted to be in the third elastic state, so that the disassembly is convenient, time-saving and labor-saving.
In this embodiment, the upper end surface of the mounting seat 100 is further provided with a second mounting groove 104, three tooth seats 120 are installed in the second mounting groove 104, a plurality of positioning teeth 113 are elastically and telescopically installed in the tooth seats 120, and the lower end surface of the tooth seat 120 is further provided with a receiving groove 121, so that part of the positioning teeth 113 are completely retracted into the receiving groove 121 in the sliding process of the elastic tube fixing mechanism 200. The accommodating groove 121 is internally provided with stepped holes 122, and the number of the stepped holes is consistent with that of the positioning teeth 113;
wherein, the small hole 123 in the stepped hole 122 is positioned above and the large hole 124 is positioned below; the positioning teeth 113 comprise a tooth body 1133 and a guide post 1134, the guide post 1134 is arranged in the small hole 123, and the size of the guide post 1134 is matched with that of the small hole 123, so that the positioning teeth 113 can slide up and down to stretch and retract; the large hole 124 is provided therein with an elastic unit 125, the upper end of which abuts against the lower end surface of the guide post 1134, so that the positioning teeth 113 can elastically stretch and retract.
It can be understood that the elastic unit 125 of the present embodiment is an active spring, so as to adjust the elastic coefficient of the elastic unit 125, and further adjust the positioning teeth 113 to be in the first elastic state, the second elastic state or the third elastic state. Preferably, the elastic unit 125 is a magnetorheological elastomer.

In this embodiment, an adjusting component 130 is disposed on one side of each of the three tooth holders 120, the adjusting component 130 can quantitatively adjust the sliding distance between the tooth holders 120, and the adjusting component 130 can limit the position of the tooth holders 120 after adjustment. Preferably, the adjustment assembly 130 is a hydraulic stem.
The integrated hoisting device for the aircraft weapon hanger of the embodiment is used for installing the bullet barrel fixing mechanism 200 with different sizes and installing bullet barrel fixing mechanisms 200 at different positions:
for the travel of the spring tube fixing mechanism 200 to be an integral multiple of the length of the positioning teeth 113, only the elastic coefficient of a part of the elastic units 125 needs to be adjusted; for strokes less than one time the length of the positioning teeth 113, only the adjustment assembly 130 need be adjusted; for a stroke greater than one and not an integer multiple of the length of the positioning teeth 113, the spring rate of the partial spring unit 125 and the adjustment assembly 130 need to be adjusted in combination.
The distance D that the adjustment assembly 130 needs to change is:
d is the distance the adjustment assembly 130 needs to change, L is the travel of the cartridge holder 200, n is a positive integer, and D is the length of the positioning teeth 113.
Through the formula of the distance change of the adjusting component 130, the distance of the adjusting component 130 needing left-right displacement can be calculated rapidly and accurately, and the position of the positioning teeth 113 can be adjusted conveniently and quickly.
