Description

Technical Field

[0001] The utility model belongs to the technical field of aircraft component storage tools, and particularly relates to an aircraft tail cover storage bracket. Background Technique

[0002] The tail cover is one of the components of an aircraft. After the tail cover is removed from the aircraft, the removed tail cover needs to be stored in a warehouse, and then reinstalled after the engine and corresponding pipelines are installed. Since the tail cover is a large sheet metal formed part with the characteristics of heavy weight, large volume and inconvenient movement, it is necessary to use a storage bracket to support and place it.

[0003] At present, during the use of the existing aircraft tail cover storage bracket, the aircraft tail cover is usually directly placed on the storage bracket for moving and handling. During the movement, the aircraft tail cover on the storage bracket may tilt to one side due to the lack of a good limiting structure during bumps, resulting in the skew of the aircraft tail cover and affecting the stability during storage. Content of the Utility Model

[0004] The purpose of the utility model is to provide an aircraft tail cover storage bracket, aiming to solve the problem that during the use of the existing aircraft tail cover storage bracket, the aircraft tail cover is usually directly placed on the storage bracket for moving and handling, and during the movement, the aircraft tail cover on the storage bracket may tilt to one side due to the lack of a good limiting structure during bumps, resulting in the skew of the aircraft tail cover and affecting the stability during storage.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an aircraft tail cover storage bracket, including a moving chassis, two auxiliary brackets are respectively connected to both sides of the moving chassis, casters are installed at the bottom of the moving chassis and the auxiliary brackets, and a bidirectional threaded rod is arranged inside the moving chassis;

[0006] One end of the bidirectional threaded rod is connected with a first bevel gear, a rotating rod penetrates through the top of the moving chassis, a second bevel gear is connected to one end of the rotating rod, an adjusting disc is connected to one end of the rotating rod, and two threaded connection blocks are threadedly connected to the outer wall of the bidirectional threaded rod, and a limiting frame is connected to the top of the two threaded connection blocks.

[0007] Preferably, both ends of the bidirectional threaded rod are rotationally connected to the moving chassis through bearings.

[0008] Preferably, the first bevel gear and the second bevel gear are meshed with each other.

[0009] Preferably, for an aircraft tail cover storage bracket of the present utility model, a sliding groove is provided at the bottom of the movable chassis, and sliders are connected to the bottoms of the two threaded connection blocks.

[0010] Preferably, for an aircraft tail cover storage bracket of the present utility model, the two threaded connection blocks can form a sliding connection structure with the movable chassis through the sliding groove and the sliders.

[0011] Preferably, for an aircraft tail cover storage bracket of the present utility model, a connecting rod penetrates through the surface of the limiting frame. One end of the connecting rod is connected with an anti-slip pad, the other end of the connecting rod is connected with a limiting block, and a spring is sleeved on the outer wall of the connecting rod.

[0012] Preferably, for an aircraft tail cover storage bracket of the present utility model, the anti-slip pad can form an elastic structure with the limiting frame through the connecting rod, the limiting block and the spring.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] By placing the aircraft tail cover sleeve on the storage bracket composed of the movable chassis and the auxiliary support, at this time, the two limiting frames will be located inside the aircraft tail cover. Then, by rotating the rotating rod through the adjusting disc, the two-way threaded rod is driven to rotate by the meshing relationship between the first bevel gear and the second bevel gear. At this time, the two threaded connection blocks threaded on its outer wall will move towards each other along the sliding groove under the action of the sliders, so that the anti-slip pads on the sides of the two limiting frames can contact the inner wall of the aircraft tail cover, thereby being able to limit the aircraft tail cover.

[0015] Through the elastic structure between the anti-slip pad and the limiting frame, the anti-slip pad can be telescoped after contacting the arc-shaped inner wall of the aircraft tail cover. Therefore, it is easier for the anti-slip pads at different positions to contact the arc-shaped inner wall of the aircraft tail cover, thereby further improving the stability during placement.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-5 , the present utility model provides the following technical solutions: An aircraft tail cover storage bracket, including a movable chassis 1, two auxiliary supports 2 are respectively connected to both sides of the movable chassis 1, casters 3 are installed at the bottoms of the movable chassis 1 and the auxiliary supports 2, and a bidirectional threaded rod 4 is arranged inside the movable chassis 1;

[0025] It should be noted that the caster 3 is a self-locking universal wheel;

[0026] One end of the bidirectional threaded rod 4 is connected to a first bevel gear 5, a rotating rod 6 penetrates through the top of the movable chassis 1, one end of the rotating rod 6 is connected to a second bevel gear 7, one end of the rotating rod 6 is connected to an adjusting disc 8, and two threaded connection blocks 9 are threadedly connected to the outer wall of the bidirectional threaded rod 4, and two limiting frames 10 are connected to the tops of the two threaded connection blocks 9.

[0027] Preferably: Both ends of the bidirectional threaded rod 4 are rotationally connected to the movable chassis 1 through bearings, and the first bevel gear 5 and the second bevel gear 7 are meshed with each other.

[0028] During specific use, by placing the aircraft tail cover on the storage bracket formed by the combination of the movable chassis 1 and the auxiliary support 2, at this time, the two limiting frames 10 will be located inside the aircraft tail cover, and then the rotating rod 6 is rotated through the adjusting disc 8, and the first bevel gear 5 and the second bevel gear 7 are used to drive the bidirectional threaded rod 4 to rotate through the meshing relationship. At this time, the two threaded connection blocks 9 threadedly connected to its outer wall can drive the limiting frames 10 on the top to move towards each other, so that the anti-slip pad 14 can contact the inner wall of the aircraft tail cover, thereby being able to limit the aircraft tail cover;

[0029] It should be noted that when the adjustment disc 8 is rotated clockwise, the two limit frames 10 can move towards each other, so that the anti-slip pads 14 are separated from the inner wall of the aircraft tail cover; on the contrary, when the adjustment disc 8 is rotated counterclockwise, the two limit frames 10 can move in opposite directions, so that the anti-slip pads 14 are in contact with the inner wall of the aircraft tail cover.

[0030] Preferably: a chute 11 is provided at the bottom of the movable chassis 1, and sliders 12 are connected to the bottoms of the two threaded connection blocks 9. The two threaded connection blocks 9 can form a sliding connection structure with the movable chassis 1 through the chute 11 and the sliders 12.

[0031] During specific use, through the sliding connection structure between the threaded connection block 9 and the movable chassis 1, when the bidirectional threaded rod 4 rotates, the chute 11 and the sliders 12 can play a guiding role when the threaded connection block 9 moves, thereby improving the stability during movement.

[0032] Preferably: a connecting rod 13 penetrates through the surface of the limit frame 10. One end of the connecting rod 13 is connected with an anti-slip pad 14, the other end of the connecting rod 13 is connected with a limit block 15, and a spring 16 is sleeved on the outer wall of the connecting rod 13. The anti-slip pad 14 can form an elastic structure with the limit frame 10 through the connecting rod 13, the limit block 15 and the spring 16.

[0033] During specific use, through the elastic structure between the anti-slip pad 14 and the limit frame 10, the anti-slip pad 14 can expand and contract after contacting the arc-shaped inner wall of the aircraft tail cover, so that the anti-slip pads 14 at different positions can more easily contact the arc-shaped inner wall of the aircraft tail cover, thereby further improving the stability during placement;

[0034] It should be noted that the anti-slip pad 14 is made of rubber material with elasticity and wear resistance. Three anti-slip pads 14 are provided on one side of each of the two limit frames 10. Since the cross-section of the aircraft tail cover is arc-shaped, the anti-slip pads 14 at different contact positions will squeeze the spring 16 to different degrees after contacting the inner wall.

[0035] Working principle: First, place the aircraft tail cover sleeve on the storage bracket composed of the movable chassis 1 and the auxiliary bracket 2. At this time, the two limit brackets 10 will be located inside the aircraft tail cover. Then, rotate the rotating rod 6 counterclockwise through the adjusting disc 8, and drive the bidirectional threaded rod 4 to rotate by using the meshing relationship between the first bevel gear 5 and the second bevel gear 7. At this time, the two threaded connection blocks 9 connected by threads on its outer wall will move towards each other along the sliding groove 11 under the action of the slider 12, so that the anti-slip pads 14 on the sides of the two limit brackets 10 can contact the inner wall of the aircraft tail cover, thereby being able to limit the aircraft tail cover. And through the elastic structure between the anti-slip pad 14 and the limit bracket 10, the anti-slip pad 14 can expand and contract after contacting the arc-shaped inner wall of the aircraft tail cover, so that the anti-slip pads 14 at different positions can more easily contact the arc-shaped inner wall of the aircraft tail cover, thereby further improving the stability during placement.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
