Description

Technical Field

[0001] This utility model relates to the field of bomb carrier bracket technology, specifically an adjustable height bomb carrier bracket. Background Technology

[0002] In modern military systems, the versatility and efficiency of fighter jet missions rely heavily on the rapid and precise loading of munitions. The munition loading vehicle carrier has emerged as a crucial piece of equipment specifically designed to assist fighter jets in loading various types of munitions. At airports, military bases, and other locations, munition loading vehicles transport different types of munitions, such as aerial bombs, missiles, and rockets, from the ground to the aircraft's loading points. Due to the wide variety of fighter jet models, with differences in loading point height and fuselage structure, the height-adjustable munition loading vehicle carrier can flexibly adjust its height to adapt to the loading requirements of different fighter jets, ensuring smooth munition loading operations.

[0003] In the prior art, such as the Chinese patent CN218777580U, a shell loading vehicle includes: a frame, comprising a moving surface and a mounting surface facing away from each other, with a lifting platform provided on the mounting surface; a moving device disposed on the moving surface for driving the frame to move; a lifting device disposed on the frame, partially extending beyond the moving surface, wherein the distance by which the lifting device extends beyond the moving surface is less than the distance by which the moving device extends beyond the moving surface, and the lifting device is tractively connected to the lifting platform to drive the lifting platform away from or towards the mounting surface; and a shell carrier assembly disposed on the lifting platform, having adjustable diameter placement positions for placing shells of different diameters. This allows for shell loading of aircraft within a relatively small operating space, is easy to operate, has high loading efficiency, and is suitable for shells of different diameters.

[0004] While the aforementioned patent can load shells, it still has some problems. When it is necessary to place shells of different diameters, the shell carrier needs to be rotated and then bolts are used to re-fix it, which reduces the efficiency of placing shells of different diameters. At the same time, after the shells are placed, it is difficult to rotate and adjust them. Therefore, this utility model provides an adjustable height shell carrier. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an adjustable-height ammunition carrier bracket, which solves the problem that when placing ammunition of different diameters, it is necessary to rotate the ammunition carrier and then use bolts to re-secure it, thus reducing the efficiency of placing ammunition of different diameters. At the same time, it is difficult to rotate and adjust the ammunition after it has been placed.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: an adjustable height shell carrier bracket, including a base plate, a lifting assembly at the top of the base plate, and two placement components at the top of the lifting assembly;

[0007] The lifting assembly includes two mounting brackets. A first housing is fixedly mounted on the top of the mounting bracket. A threaded screw is rotatably mounted on the inner wall of the first housing. The bottom end of the threaded screw passes through the inner wall of the mounting bracket and is fixedly mounted with a first bevel gear. A second bevel gear is meshed on the outer wall of the first bevel gear.

[0008] The placement assembly includes a placement frame, two placement rollers are rotatably mounted on the inner wall of the placement frame, two side plates are rotatably mounted on the inner wall of the placement frame, and a support plate is rotatably provided on one side of the outer wall of the side plates.

[0009] Preferably, the outer wall of the threaded screw is threadedly connected to a first movable slider, the first movable slider is movably inserted into the inner wall of the mounting bracket, and a movable plate is fixedly installed at the top of the first movable slider.

[0010] Preferably, both mounting brackets are fixedly mounted on the top of the base plate, a rotating rod is rotatably mounted between opposite sides of the two mounting brackets, both second bevel gears are fixedly connected to the rotating rod, and a worm gear is rotatably mounted on the inner wall of one of the two mounting brackets.

[0011] Preferably, a worm wheel is engaged on one side of the outer wall of the worm, the worm wheel is fixedly connected to the rotating rod, and a rocker arm is fixedly installed on one side of the outer wall of the worm through the outer wall of the mounting frame.

[0012] Preferably, a second housing is fixedly installed at the top of the placement rack, and a bidirectional screw is rotatably installed on the inner wall of the second housing. Two second movable sliders are threadedly connected to the outer wall of the bidirectional screw.

[0013] Preferably, one side of the outer wall of the second movable slider is rotatably connected to the support plate, one end of the outer wall of the support plate is rotatably connected to the side plate, one end of the outer wall of the bidirectional screw penetrates the outer wall of the second housing and is fixedly mounted with a rotating plate, and the two placement racks are respectively fixedly connected to the two movable plates. Beneficial effects

[0014] This invention provides an adjustable-height missile loading vehicle bracket. Compared with the prior art, it has the following advantages:

[0015] (1) When the adjustable height shell-mounting bracket needs to be used for shell mounting, the shell is first placed on the surface of the two placement rollers so that the shell contacts the surface of the placement rollers. The rotating plate is then rotated to drive the bidirectional screw to rotate inside the second housing. The two second movable sliders connected to the outer wall of the bidirectional screw will move in opposite directions due to the bidirectional thread characteristics of the screw. As the second movable sliders move, the support plate pushes the side plate to rotate around the inner wall of the placement frame, thereby changing the distance between the two side plates to accommodate the placement of shells of different diameters. This allows for rapid adaptation to shells of different diameters. At the same time, since the shell is placed on the surface of the placement rollers, the friction force on the shell during rotation is reduced, making it convenient for operators to adjust the angle of the shell.

[0016] (2) When the height of the projectile needs to be adjusted, the adjustable height projectile carrier bracket can rotate the rocker arm to drive the worm gear to rotate. Since the worm gear meshes with the worm wheel, the rotation of the worm wheel drives the rotating rod to rotate. The second bevel gears fixedly connected to both ends of the rotating rod rotate accordingly and mesh with the first bevel gear, causing the threaded screw to rotate. The first movable slider connected to the threaded screw can only move along the screw axis under the constraint of the inner wall of the mounting bracket, thereby driving the movable plate to move up and down, realizing the adjustment of the projectile height. Through the transmission of the worm gear, worm wheel and bevel gear, the height of the projectile can be easily adjusted by simply rotating the rocker arm, which greatly improves the adjustment efficiency, can quickly adapt to the height of different aircraft mounting points, and improves the overall efficiency of projectile loading operations.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides two technical solutions:

[0025] Figures 1-5 The first embodiment is shown: an adjustable height shell carrier bracket, including a base plate 1, a lifting assembly 2 is provided at the top of the base plate 1, and two placement assemblies 3 are provided at the top of the lifting assembly 2;

[0026] The lifting assembly 2 includes two mounting brackets 21. A first housing 22 is fixedly mounted on the top of the mounting bracket 21. A threaded screw 23 is rotatably mounted on the inner wall of the first housing 22. The bottom end of the threaded screw 23 passes through the inner wall of the mounting bracket 21 and is fixedly mounted on a first bevel gear 25. A second bevel gear 26 is meshed on the outer wall of the first bevel gear 25. When the second bevel gear 26 rotates, it can drive the first bevel gear 25 and the threaded screw 23 to rotate.

[0027] The placement assembly 3 includes a placement frame 32. Two placement rollers 33 are rotatably mounted on the inner wall of the placement frame 32. The shells can be placed on the surface of the placement rollers 33. Since the placement rollers 33 can rotate, the difficulty of rotating the shells is reduced. Two side plates 38 are rotatably mounted on the inner wall of the placement frame 32. By adjusting the angle of the two side plates 38, the side plates 38 can be adapted to shells of different diameters and can hold shells of different diameters. A support plate 37 is rotatably provided on one side of the outer wall of the side plate 38.

[0028] The outer wall of the threaded screw 23 is threadedly connected to a first movable slider 24. The first movable slider 24 is movably inserted into the inner wall of the mounting bracket 21. A movable plate 210 is fixedly installed on the top of the first movable slider 24. When the threaded screw 23 rotates, it can drive the first movable slider 24 and the movable plate 210 to rise and fall.

[0029] Both mounting brackets 21 are fixedly mounted on the top of the base plate 1. A rotating rod 29 is rotatably mounted between the opposite sides of the two mounting brackets 21. Both second bevel gears 26 are fixedly connected to the rotating rod 29. A worm gear 28 is rotatably mounted on the inner wall of one of the two mounting brackets 21. The rotating rod 29 can simultaneously drive the two second bevel gears 26 to rotate.

[0030] Figures 1-5 The second embodiment is shown. The main difference from the first embodiment is that a worm wheel 27 is engaged on one side of the outer wall of the worm 28. The worm wheel 27 is fixedly connected to the rotating rod 29. One side of the outer wall of the worm 28 penetrates the outer wall of the mounting bracket 21 and is fixedly mounted with a rocker arm 211. Rotating the rocker arm 211 can drive the worm 28 to rotate, which in turn drives the worm wheel 27 to rotate, which in turn drives the rotating rod 29 to rotate.

[0031] A second housing 34 is fixedly installed on the top of the placement frame 32. A bidirectional screw 35 is rotatably installed on the inner wall of the second housing 34. Two second movable sliders 36 are threadedly connected to the outer wall of the bidirectional screw 35.

[0032] One side of the outer wall of the second movable slider 36 is rotatably connected to the support plate 37, and one end of the outer wall of the support plate 37 is rotatably connected to the side plate 38. One end of the outer wall of the bidirectional screw 35 passes through the outer wall of the second housing 34 and is fixedly mounted with a rotating plate 39. The two placement brackets 32 are respectively fixedly connected to the two movable plates 210. The rotating plate 39 can drive the bidirectional screw 35 to rotate, and the bidirectional screw 35 can then drive the two second movable sliders 36 to move. The second movable sliders 36 can then drive the side plate 38 to rotate through the support plate 37.

[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0034] During operation, when loading shells, the shells are first placed on the surfaces of the two placement rollers 33, ensuring contact between the shells and the roller surfaces. Then, the rotating plate 39 is rotated, driving the bidirectional screw 35 to rotate within the second housing 34. Two second movable sliders 36, threaded to the outer wall of the bidirectional screw 35, move in opposite directions due to the screw's bidirectional thread characteristics. As the second movable sliders 36 move, the support plate 37 pushes the side plates 38 to rotate around the inner wall of the placement frame 32, thereby changing the distance between the two side plates 38 to accommodate shells of different diameters. This allows for rapid adaptation to different diameter shells. Simultaneously, because the shells are placed on the surfaces of the placement rollers 33, the friction experienced during shell rotation is reduced, facilitating angle adjustment by operators. When shell height adjustment is required, the rocker arm 211 is rotated, driving the worm gear 28 to rotate. Since the worm gear 28 meshes with the worm wheel 27, the rotation of the worm wheel 27 drives the rotating rod 29 to rotate. The second bevel gear 26, which is fixedly connected to both ends of the rotating rod 29, rotates accordingly and meshes with the first bevel gear 25, causing the threaded screw 23 to rotate. The first movable slider 24, which is threadedly connected to the threaded screw 23, can only move along the screw axis under the constraint of the inner wall of the mounting bracket 21, thereby driving the movable plate 210 to move up and down, thereby adjusting the height of the projectile.
