The delivery rack system 3 can move back and forth along the guide rail, and is used to place the delivered object and drive the delivered object to move to the exit of the cabin to the vicinity of the exit of the cabin through the delivery rack system 3. The traction parachute system 2 is used to connect with the delivered object through the connecting rope 9 and tow the delivered object out of the aircraft; the traction parachute system 2 can realize the reliable traction of the delivered object out of the aircraft, the delivery rack system can realize the reliable mooring and fixing of the delivered object in the cabin, and drive the delivered object to move to the exit of the cabin and release the mooring, and lock the delivery rack system (locking means that the delivery rack system does not move in the cabin).

[0034] Example 2 The delivery rack system is further limited on the basis of Example 1, and the performance of Example 2 after the limitation is even better.

[0035] Furthermore, the delivery rack system includes a delivery rack body 10, and a plurality of movable rollers 11 are sequentially arranged on both sides of the delivery rack body 10 along the length direction of the delivery rack body 10, and the delivery rack body 10 slides along the guide rails in the cabin through the movable rollers 11; The delivery rack body 10 is also provided with a supporting structure, a mooring and separation mechanism and a locking mechanism. The supporting structure is used to form a supporting surface to support the object to be delivered, the mooring and separation mechanism is used to moor the object to be delivered and the delivery rack body 10 to fix or separate it, and the locking mechanism is used to lock the delivery rack body 10 on the guide rail or in the cabin.

[0036] Furthermore, the locking mechanism may be an automatic locking pin, which is inserted into a locking socket on the cabin floor or on the guide rail.

[0037] Furthermore, the support structure includes multiple groups of support roller assemblies arranged in sequence along the length direction of the delivery rack body 10, and each group of support roller assemblies includes two support rollers arranged in a V shape; the support mechanism is a "V"-shaped support structure, which is used to form a support surface to support the object being delivered, and the support mechanism is connected to the delivery rack body by bolts.

[0038] Furthermore, the support roller includes a clamping shaft 19, a support wheel 20, a bearing 21 and a support shaft 22. The support wheel 20 is sleeved on the support shaft 22 through the bearing 21. The clamping shaft 19 is arranged on the support shaft 22, close to the bearing 21 and the lower end surface of the support wheel 20, and the support wheel and the bearing are positioned on the support shaft through the clamping shaft; the support shaft 22 of the support roller is connected to the delivery rack body 10 through bolts, the surface is a support wheel, and a bearing is arranged inside, which ensures that the object placed on the support mechanism can roll on the delivery rack, and the combination of the support wheel and the bearing is positioned on the support shaft through the clamping shaft.

[0039] Furthermore, the mooring separation mechanism includes a separation mechanism 17 and a mooring belt 15, the separation mechanism 17 is fixed on the delivery rack body 10 by threads, and the object to be delivered is connected to the separation mechanism 17 by the mooring belt 15; wherein, the separation mechanism 17 is a pyrotechnic separation component, and when the signal sensing module 18 sends a release signal, the gunpowder inside the separation mechanism 17 is actuated to separate the threaded part at the bottom of the separation mechanism 17 from the upper end, thereby realizing the automatic release of the mooring belt 15.

[0040] A signal sensing module 18 is also provided on the delivery rack body 10, and the signal sensing module 18 is connected to the separation mechanism 17; the separation mechanism is used to reliably tether the delivery rack system in the cabin to the delivered object through a tethering belt. When the signal sensing module 18 detects that the delivered object moves to the corresponding position with the delivery rack system, the separation mechanism releases the tethering belt and separates from the delivered object, thereby also separating the delivered object from the delivery rack system.

[0041] Furthermore, the front and rear ends of the delivery rack body 10 are respectively provided with a locking latch hole 23 and a locking latch 14. When two adjacent delivery rack bodies 10 are spliced, the locking latch 14 of one delivery rack body 10 is inserted into the locking latch hole 23 of another adjacent delivery rack body 10, and the locking latch 14 is inserted into the locking groove 26, so that the delivery rack system 3 is locked after reaching a predetermined position; A locating pin hole 24 is provided on the hole wall of the locking pin hole 23, and an elastic locating pin for inserting into the locating pin hole 24 is provided at a corresponding position on the side wall of the locking pin 14; when the locking pin 14 is inserted into the locking pin hole 23, the elastic locating pin enters the locking pin hole 23 with the locking pin 14, and before the elastic locating pin moves to the locating pin hole 24, the elastic locating pin is compressed into the locking pin 14 until the elastic locating pin moves to the bottom of the locating pin hole 24, and the elastic locating pin pops out from the locking pin 14 and is inserted into the locating pin hole 24, forming a locking after the locking pin 14 is inserted into the locking pin hole 23, thereby realizing the mutual locking of two adjacent delivery rack bodies.

[0042] The elastic positioning pin includes a wedge-shaped head. A mounting slot is provided on the side wall of the locking pin 14. The wedge-shaped head is arranged in the mounting slot. A spring is provided between the wedge-shaped head and the bottom of the mounting slot.

[0043] A locking groove 26 is also provided on the delivery rack body 10 along the length direction of the guide rail, and the positioning pin hole 24 is arranged in the locking groove 26. The locking groove 26 is used to guide the movement of the elastic positioning pin so that the elastic positioning pin can be accurately inserted into the positioning pin hole 2 after moving to the corresponding position. After the locking pin 14 is inserted, the elastic positioning pin pops up and inserts into the locking groove 26. The locking pin 14 is inserted into the locking pin hole 23 and moves. At the same time, the elastic positioning pin also moves back and forth along the length direction of the locking groove 26.

[0044] A plurality of small pulleys 25 are provided between the delivery rack body 10 and the guide rail.

[0045] Furthermore, the locking pin and locking hole in the present solution are used to lock the delivery rack system after the delivery rack system reaches a predetermined position when it moves along the T-shaped guide rail (the predetermined position refers to when the first group of delivery rack systems moves to contact with the end stopper and the rear delivery rack system moves to contact with the front delivery rack), ensuring that the delivery rack is reliably locked in the machine and preventing the delivery rack body from running around in a panic.

[0046] Furthermore, the locking pin 14 wraps the overall transverse cylindrical structure and the wedge-shaped head above, and there is a spring below the wedge-shaped head (inside the transverse cylindrical structure). When two adjacent delivery rack bodies 10 are spliced, the locking pin 14 of one delivery rack body 10 will be inserted into the locking pin hole 23 of the other adjacent delivery rack body 10 (the relationship between the axis and the hole, the transverse cylindrical structure of the locking pin 14 and the locking pin hole 23 are on the same axis). During the insertion process, the wedge-shaped head above the locking pin 14 will be blocked by the upper edge of the locking pin hole 23 and compressed by the spring below the wedge-shaped head (equivalent to the existence of the wedge-shaped head above the locking pin 14 so that its upper part is higher than the outer diameter of the locking pin hole 23). The insertion process is the process of the wedge head being compressed and lowered. When the locking pin 14 passes through the locking pin hole 23 and completely enters the locking groove 26, there is no longer any obstruction above the wedge head, and it bounces up under the action of the spring, thereby achieving locking. The locking socket 23 is an insertion guide hole on the side of the delivery rack body 10, which is used for the coaxial insertion of the locking pin 14. The locking groove 26 is a rectangular hole on the top of the delivery rack body 10, which is used for the locking pin 14 to pop up its wedge-shaped head after being inserted and to get it stuck in the locking groove 26 so that it cannot come out. Therefore, the locking pin is connected to the automatic locking mode during the movement of the delivery rack 10. For unhooking, it is necessary to manually press the wedge-shaped head above the locking pin 14 after the system is finished working to make it come out of the locking groove 26, so as to realize the unlocking between the two delivery racks.

[0047] Furthermore, an end stopper 4 is provided at the end of the guide rail; the end stopper is used to be set at the end of the guide rail to block the delivery rack body from leaving the cabin.

[0048] Furthermore, a locking pin hole 23 is also correspondingly provided on the end stopper 4, which is used to be inserted and locked with the locking pin 14 on the delivery rack body closest to the hatch opening, so that the delivery rack body can be locked in position and its impact force can be offset when it moves to the hatch opening, preventing the delivery rack body from sliding and running around along the guide rail; a positioning pin hole 24 is provided on the hole wall of the locking pin hole 23, and an elastic positioning pin for inserting into the positioning pin hole 24 is provided at a corresponding position on the side wall of the locking pin 14.

[0049] Furthermore, a buffer block 16 is provided at the front end and / or rear end of the delivery rack body 10; the buffer block 16 is used for buffer release after the delivery rack moves to a predetermined position, and the buffer block 16 absorbs and releases the collision energy when the delivery rack system 3 contacts the end stopper 4 / delivery rack system 3.

[0050] Furthermore, the traction parachute system includes a traction parachute, a connecting mechanism and a connecting rope, one end of the connecting rope 9 is connected to the traction parachute 7, and the other end of the connecting rope 9 is connected to the connecting mechanism 8. The connecting mechanism 8 is connected to multiple connecting branch ropes, each connecting branch rope is used to connect to the object to be dropped, and the traction parachute 7 is set on the cabin door before dropping; a main rope is divided into multiple ropes through the connecting mechanism 8 and then connected to the hanging point of the object to be dropped.

[0051] Furthermore, the cross-section of the delivery rack body 10 is a C-shaped structure, and the cross-section of the guide rail is a T-shaped structure. The C-shaped structure of the delivery rack body matches the T-shaped structure of the guide rail, and the C-shaped delivery rack body 10 is wrapped around the T-shaped guide rail.

[0052] Furthermore, the main body of the delivery rack is a "C"-shaped structure, and is equipped with a moving roller 11 to ensure the movement of the delivery rack in the cabin. The "C"-shaped structure matches the T-shaped guide rail 5 in the cabin to achieve left and right and up and down limits of the delivery rack in the cabin, and at the same time has an in-machine motion guiding function, so that the delivery rack can move along the T-shaped guide rail. A small pulley is arranged on the inside to ensure the smoothness of movement. The front and rear limits of the delivery rack system are achieved by inserting the positioning pins through the delivery rack and the T-shaped guide rail at the same time. There are three groups of delivery rack systems, the delivery rack systems 3 close to the hatch are the first group, the delivery rack systems 3 far from the hatch are the third group, and the delivery rack systems 3 in the middle are the second group.

[0053] An airdrop method using the above-mentioned airdrop system comprises the following steps: Before the delivery begins, the delivered object 1, the traction parachute system 2, the delivery rack system 3, and the end stopper 4 are reasonably arranged in the cabin 6. After the delivery begins, the positioning lock of the positioning pin 13 of the delivery rack system 3 is first released, and the traction parachute 7 of the traction parachute system is lowered. Under the action of the airflow, the traction parachute 7 of the traction parachute system opens, and the traction force is generated at this time to pull the delivered object and the delivery rack system through the traction rope to start moving toward the hatch exit; When the first group of delivery rack systems 3 reaches the predetermined position, the first group of delivery rack systems 3 releases the mooring of the delivered object 1, and at the same time, the locking pin 14 thereof is locked with the end stopper 4, and the airdrop system continues to move; when the second group of delivery rack systems 3 reaches the predetermined position, the second group of delivery rack systems 3 releases the mooring of the delivered object 1, and at the same time, the locking pin 14 thereof is locked with the first group of delivery rack systems 3, and the airdrop system continues to move; when the third group of delivery rack systems 3 reaches the predetermined position, the third group of delivery rack systems 3 releases the mooring of the delivered object 1, and at the same time, the locking pin 14 thereof is locked with the second group of delivery rack systems 3, and at this time, all three groups of delivery rack systems 3 complete the release of the mooring of the delivered object 1 and their own locking; the delivered object 1 continues to move under the action of the traction parachute 7 and its own gravity until it completely exits the cabin.

Under the action of the airflow, the traction parachute 7 is opened, and the traction force is generated at this time to pull the system to start moving through the traction rope. When the first group of delivery rack systems 3 reaches the predetermined position, the first group of delivery rack systems 3 releases the mooring of the delivered object 1, and at the same time, the locking pin 14 thereof is locked with the end stopper 4, and the airdrop system continues to move; when the second group of delivery rack systems 3 reaches the predetermined position, the second group of delivery rack systems 3 releases the mooring of the delivered object 1, and at the same time, the locking pin 14 thereof is locked with the first group of delivery rack systems 3, and the airdrop system continues to move; when the third group of delivery rack systems 3 reaches the predetermined position, the third group of delivery rack systems 3 releases the mooring of the delivered object 1, and at the same time, the locking pin 14 thereof is locked with the second group of delivery rack systems 3, and at this time, all three groups of delivery rack systems 3 complete the release of the mooring of the delivered object 1 and their own locking; the delivered object 1 continues to move under the action of the traction parachute 7 and its own gravity until it completely exits the cabin.

[0062] In other optional embodiments, the configuration of the delivery rack system 3 , the overall height of the delivery rack body 10 , the number of support mechanisms 12 and other features can be flexibly designed according to the characteristics of the object 1 to be delivered.

[0063] In summary, the present invention provides a delivery stand type airdrop system, which overcomes the shortcomings of the existing airdrop system that the objects being dropped cannot be discharged from the cabin individually, and the airdrop system is large in size and weight, and the mooring, bundling and release are complicated. The airdrop system greatly reduces the overall size and weight of the airdrop system, simplifies the mooring, bundling and release work, and can discharge the objects from the cabin without the delivery stand. The present invention is simple and effective to implement, and solves the shortcomings of the existing airdrop system that the objects are large in size and weight, and the mooring, bundling and release are complicated. At the same time, the system characteristics of the delivery stand enable it to be flexibly arranged according to the characteristics of the objects being dropped, so as to meet the airdrop requirements of the objects being dropped to be discharged from the cabin individually, and has high versatility and a wide range of applications.
