Description

Technical Field

[0001] The invention relates to the technical field of aviation engine packaging boxes, in particular to a push-pull type aviation engine packaging box. Background Art

[0002] As a key equipment for the transportation and storage of aircraft engines, aircraft engine packaging boxes bear the important responsibility of shielding, sealing and protecting the engine. In terms of operation, the packaging boxes should meet the needs of convenience and quick response to engine installation and disassembly.

[0003] Given the large size of aircraft engines, the size of their packaging boxes is also relatively large. Such large engine boxes generally adopt a semi-opening box structure, that is, the packaging box consists of two main parts: the box bottom and the box cover, which are tightly connected by a quick-release device. During the opening or closing of the box, the box cover needs to be lifted with the help of lifting equipment. However, this packaging box structure has the following shortcomings:

[0004] The joint surface of the packaging box along the length and width direction is too long, generally reaching more than ten meters or even more than twenty meters, which undoubtedly increases the difficulty of sealing the bottom and cover of the box;

[0005] Since a large number of quick-release devices are installed along the length and width of the packaging box, the operation time is long during the process of opening, fastening and lifting the box cover, and usually at least four people are required to work together (one person operates the crane, two people support the box cover, and one person is responsible for safety supervision), which makes it difficult to meet the needs of rapid response to engine installation and disassembly;

[0006] When lifting the cover of the packaging box, it is difficult to control the lifting point and the center of mass of the cover, which can easily cause the cover to shake in the vertical direction, thereby increasing the risk of collision with the engine.

[0007] Therefore, based on the above technical problems, it is necessary for technicians in this field to develop a push-pull type aircraft engine packaging box. Summary of the invention

[0008] The object of the present invention is to provide a push-pull type aircraft engine packaging box to solve the common problems raised in the above background technology.

[0009] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a push-pull type aircraft engine packaging box, comprising a left half box body and a right half box body which are relatively distributed, a slide rail assembly is arranged between the left half box body and the right half box body, the slide rail assembly comprises two groups of guide rails, the two groups of guide rails are distributed in parallel, a left slider mounting plate is installed on the relative inner wall of the left half box body, a left slider is installed on the left slider mounting plate, the left slider is slidably connected to the outside of the guide rail, a right slider mounting plate is installed on the relative inner wall of the right half box body, a right slider is installed on the right slider mounting plate, the right slider is slidably connected to the guide rail, and fixed seats are installed on the backs of the left slider mounting plate and the right slider mounting plate, and the fixed seats are connected to the box wall.

[0010] As a preferred technical solution, rubber pads are installed on the inner walls of the left and right half boxes at both ends of the guide rails, and a stopper is installed on the end face of the guide rails in the left half box to prevent the guide rails from sliding out of the left slider and falling off when opening the box.

[0011] As a preferred technical solution, a spring lock pin is installed on the right sliding block, and a limiting hole is provided on the guide rail, and the limiting hole cooperates with the spring lock pin for limiting and fixing.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0027] Example

[0028] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the present invention provides a technical solution for a push-pull aircraft engine packaging box: it includes a left half box body 11 and a right half box body 12 which are relatively distributed, a slide rail assembly is arranged between the left half box body 11 and the right half box body 12, the slide rail assembly includes two groups of guide rails 31, the two groups of guide rails 31 are distributed in parallel, a left slider mounting plate 37 is installed on the opposite inner wall of the left half box body 11, a left slider 38 is installed on the left slider mounting plate 37, the left slider 38 is slidably connected to the outside of the guide rail 31, a right slider mounting plate 37 is installed on the opposite inner wall of the right half box body 12, a right slider 34 is installed on the right slider mounting plate 33, the right slider 34 is slidably connected to the guide rail 31, a spring lock pin 35 is installed on the right slider 34, a limiting hole is arranged on the guide rail 31, and the limiting hole is connected to the guide rail 31. The spring lock pin 35 cooperates with each other and is used for limiting and fixing. The backs of the left slider mounting plate 37 and the right slider mounting plate 33 are both installed with fixing seats 16, and the fixing seats 16 are connected to the box wall. Rubber pads 32 are installed on the inner walls of the left half box body 11 and the right half box body 12 at both ends of the guide rail 31. A stopper 39 is installed on the end face of the guide rail 31 located in the left half box body 11. The stopper 39 is used to prevent the guide rail 31 from sliding out and falling from the left slider 38 when opening the box. Multiple groups of supporting mounting plates 36 are arranged between the relative guide rails 31, and mounting sections 361 are arranged on the multiple groups of supporting mounting plates 36, and a connecting lower seat 362 is installed at the bottom of the mounting section 361. A bracket 363 is commonly connected between the multiple connecting lower seats 362. The bracket 363 and the mounting section 361 are used to install and support the engine.

[0029] In this embodiment, the staff can easily realize the relative sliding of the two boxes by operating the slide rail assembly between the left half box 11 and the right half box 12. When it is necessary to open the packaging box, the staff can release the locking state of the spring lock pin 35 and the limiting hole, and then push the right half box 12 to slide along the guide rail 31 to separate the left half box 11 and the right half box 12, so as to conveniently take out or put in the aircraft engine. When closing the packaging box, it is only necessary to push the right half box 12 back to its original position along the guide rail 31 and use the spring lock pin 35 to lock it with the limiting hole.

[0030] By adjusting the position and number of the supporting mounting plates 36, the packaging box can be adapted to different models and specifications of aircraft engines, thereby meeting the needs of different users. At the same time, the design of the buckle assembly also enables the packaging box to be tightly connected when closed, thereby ensuring the sealing and safety of the packaging box.

[0031] See also Figure 1 and Figure 2 As shown, observation windows 13 are provided on the opposite walls of the left half box 11 and the right half box 12, multiple sets of lifting rings 14 are provided on the outer walls on both sides of the left half box 11 and the right half box 12, and the multiple sets of lifting rings 14 are connected to the box through bolts 15, and multiple sets of brake casters 17 are installed at the bottom of the left half box 11 and the right half box 12.

[0032] In this embodiment, by providing an observation window 13, the staff can directly observe the state of the aircraft engine without opening the packaging box, thereby improving work efficiency. At the same time, the multiple sets of lifting rings 14 provided on the outer walls of both sides of the packaging box make the packaging box more stable during the lifting process, thus avoiding damage to the aircraft engine caused by improper lifting. In addition, the brake casters installed at the bottom of the packaging box also greatly improve the mobility of the packaging box, allowing the staff to easily move the packaging box to a designated location.

[0033] See also Figure 1 , Figure 2 and Figure 4 As shown, a buckle assembly 2 is arranged between adjacent edges of the left half box 11 and the right half box 12, and the buckle assembly 2 includes a buckle seat 21, and a steering seat 22 is movably connected to the buckle seat 21 through a pin shaft. The steering seat 22 is installed on the left half box 11, and a pressure handle 221 is installed at the rear of the steering seat 22. Bosses 23 are arranged on both sides of the steering seat 22, and U-shaped rods 24 are arranged through the sides of the two bosses 23, and a threaded groove 241 is arranged on the U-shaped rod 24. The threaded grooves 241 on both sides of the convex seat 23 are threadedly connected to the outside with nuts 25, a buckle hook 29 is installed on the right half of the box body 12, and the buckle hook 29 cooperates with the U-shaped rod 24, a tension spring 26 is connected to the buckle seat 21, and the tail end of the tension spring 26 is connected to the stretching seat 27, the stretching seat 27 is movably connected to the pressure handle 221 through a pin shaft, a positioning block 28 is provided on the buckle seat 21, and the lower part of the stretching seat 27 cooperates with the positioning block 28 to limit and fix the pressure handle 221.

[0034] In this embodiment, the staff can operate the pressure handle 221 to rotate the steering seat 22 around the pin, thereby driving the convex seat 23 and the U-shaped rod 24 to move. When the U-shaped rod 24 moves to a position that matches the buckle hook 29, the two ends of the U-shaped rod 24 are tightly attached to the buckle hook 29, thereby achieving a tight connection between the left half box 11 and the right half box 12. The design of the tension spring 26 and the stretching seat 27 can ensure that after the pressure handle 221 is released, the buckle assembly 2 can automatically return to the original position, which is convenient for next use. At the same time, the design of the positioning block 28 can effectively prevent the pressure handle 221 from accidentally rotating during transportation or storage, thereby ensuring the safety of the packaging box.

[0035] The working principle and use process of the present invention: When in use, the staff first places the aircraft engine on the support mounting plate 36 to ensure that the engine is stable and the weight is evenly distributed. Then, the right half box 12 is pushed toward the left half box 11 along the guide rail 31 until the adjacent edges of the two boxes are completely fitted. In this process, the design of the rubber pad 32 will play a buffering role to reduce the friction and impact between the two boxes.

[0036] When the two boxes are completely fitted together, the staff can operate the buckle assembly 2 to close them. Specifically, the pressing handle 221 is pressed down to rotate the steering seat 22 around the pin, thereby driving the convex seat 23 and the U-shaped rod 24 to move. When the two ends of the U-shaped rod 24 are aligned with the buckle hook 29, the pressing handle 221 is released, and under the action of the tension spring 26, the buckle assembly 2 automatically returns to the original position. At this time, the two ends of the U-shaped rod 24 will be tightly attached to the buckle hook 29, realizing a tight connection between the two boxes. At the same time, the positioning block 28 will prevent the pressing handle 221 from rotating accidentally, ensuring the safety of the packaging box during transportation or storage.

[0037] After the buckle assembly 2 is closed, the staff can further operate the spring lock pin 35 to lock with the limiting hole on the guide rail 31 to increase the sealing and stability of the packaging box. In the locked state, even if it encounters external impact or vibration, the packaging box can remain tightly closed to ensure the safety of the aircraft engine.

[0038] When the packing box needs to be opened, the pressing handle 221 is pulled to disengage the U-shaped rod 24 from the buckle hook 29. At this time, the right half case 12 can be pushed to slide along the guide rail 31 to separate the two cases, thereby easily taking out or putting in the aircraft engine.

[0039] During the whole use process, the staff can directly observe the state of the aircraft engine through the observation window 13, thereby improving work efficiency. Meanwhile, the multiple sets of lifting rings 14 arranged on the outer walls of both sides of the packaging box and the brake casters at the bottom will facilitate the lifting and movement of the packaging box.

[0040] The push-pull type aircraft engine packaging box technical solution provided by the present invention has the advantages of simple structure, convenient operation, safety and reliability, etc., can meet the packaging needs of aircraft engines of different models and specifications, and improve the transportation and storage efficiency of aircraft engines.
