Description

Technical Field

[0001] The present invention relates to the field of mechanical devices and transportation technology, and in particular to an aviation container pallet connecting device capable of realizing container transportation. Background Art

[0002] At present, ammunition is mostly transported by road and rail, and all are handled separately in loose pieces. This mode of transportation is time-consuming and labor-intensive, and is not conducive to the timely guarantee of ammunition during wartime. In order to provide timely and effective ammunition supply and replenishment in modern warfare and truly achieve rapid and efficient guarantee of ammunition, it is necessary to improve the efficiency of air transportation and develop ammunition transportation in the direction of containerization. The commonly used air transportation container equipment is the aviation container pallet, but the specifications of ammunition vary, and some ammunition is larger than the external dimensions of the aviation container pallet. Therefore, it is urgent to develop an aviation container pallet connection device to achieve the connection of multiple aviation container pallets, and then realize the transshipment and transportation of ammunition boxes of different specifications.

DETAILED DESCRIPTION

[0033] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0034] The present invention provides an aviation container pallet connection device that can realize container transportation, such as Figure 4 As shown, the connecting device 14 is located in the serrated grooves of the two container pallets 13 to be connected, as shown in FIG. Figure 1 、 Figure 2 As shown, it includes a base 1, a cover 2, a positioning component and a locking component.

[0035] The cover 2 is connected to one side of the upper surface of the base 1 through a rotating pin Ⅰ10 with a torsion spring, and is locked to the other side of the upper surface of the base 1 through a locking assembly. In this embodiment, the locking assembly includes a lock 8 and a hook 22, as shown in FIG. Figure 6 As shown, the contact surface between the lock catch 8 and the hook 22 forms an angle between 10° and 20° with the horizontal plane. The lock catch 8 is connected to the top surface of the base 1 via a torsion spring-loaded pivot pin II 11. The hook 22 is located on one side of the bottom surface of the cover 2. A connecting flange 23 is provided on the other side of the bottom surface of the cover 2 for mounting the torsion spring-loaded pivot pin I 10. Both pivot pins I 10 and II 11 utilize torsion springs with a wire diameter of 1 mm and an outer diameter of 4 mm, made of 12Cr18Ni9 stainless steel.

[0036] When the cover plate 2 is produced in small batches, the hook 22, the connecting flange 23 and the cover body 21 can be designed separately and connected by threads. The bottom of the hook 22 and the connecting flange 23 is a wedge-shaped structure to enhance the connection strength. Figure 8 、 Figure 9 As shown; when the cover plate 2 is mass-produced, it can be precision-cast and integrally formed, such as Figure 7 shown.

[0037] The length of the base 1 is consistent with the distance between the two pallets to be connected. There are mooring ring grooves on both sides of the upper surface of the base 1 for placing the mooring rings of the container pallets 13 to be connected on both sides; the two positioning components are located in the guide grooves on both sides of the base 1, and are used to connect the serrations of the container pallets 13 to be connected on both sides. After the initial lock of the positioning component is released, the positioning structure of the positioning component moves to the inner cavity of the adjacent serrations, and is locked again after it is in place to complete the connection of the container pallets 13.

[0038] In this embodiment, the positioning assembly includes a positioning block I4, a positioning block II5, a spring 12, and a positioning pin 9. The end of the positioning block I4 is a positioning protrusion I, i.e., a positioning structure. The main part of the positioning block I4 is provided with two positioning pin holes I along the direction of movement. The end of the positioning block II5 is a positioning protrusion II, i.e., a positioning structure. The main part of the positioning block II5 is provided with two positioning pin holes II along the direction of movement. The positioning block I4 is connected to the positioning block II5 via a spring 12, and the spring 12 is always in a compressed state. The spring 12 is wound with 12Cr18Ni9 stainless steel wire. The length of the spring 12 is approximately 60mm, the wire diameter is 1mm, and the outer diameter is approximately 4mm. The main part of the positioning block I4 and the main part of the positioning block II5 are complementary in structure. The overall height after the upper and lower parts are attached is consistent with the height of the positioning structure. At this time, the positioning pin hole I and the positioning pin hole II correspond in position and are used to cooperate with the positioning pin 9 to limit the position, corresponding to the initial locking and the in-position locking respectively. The positioning protrusion I and positioning protrusion II are placed on both sides.

[0039] The positioning assembly also includes a reset assembly, which is fixed to positioning block I4 and positioning block II5, respectively, and both are located on the main body of the end where the positioning structure is located. The reset assembly includes a pressure head 6 and a pressure head connecting column 7, which are divided into pressure head I, pressure head connecting column I, pressure head II, and pressure head connecting column II. Pressure head I is connected to positioning block I4 via pressure head connecting column I and is located on the main body of the end where positioning protrusion I is located. Pressure head II is connected to positioning block II5 via pressure head connecting column II and is located on the main body of the end where positioning protrusion II is located. Side plate 3 is threadedly connected to the side of base 1. Side plate 3 is provided with a pressure head mounting hole and a positioning structure interface. After the positioning structure is moved into position, side plate 3 limits the stepped surface at the end where the positioning structure is located.

[0040] like Figure 5 As shown, the positioning pin 9 includes a pull ring 91, a pin body 92 and a spring bead 93. The pull ring 91 is arranged at the upper end of the pin body 92, and the spring bead 93 is arranged at the lower end of the pin body 92, for locking the positioning pin 9.

[0041] In this embodiment, Figure 3 As shown, two aviation container pallets 13 are connected by four connecting devices 14. The installation process is as follows:

[0042] ① Place the aviation container pallet connection device 14 in the serrated groove, open the lock 8, open the cover 2, and place the tie-down ring in the corresponding tie-down ring groove of the base 1;

[0043] ② Pull out the positioning pin 9 to move the positioning blocks I4 and II5 into the inner cavity of the adjacent saw teeth. After moving into place, insert the positioning pin 9 to lock the positioning blocks I4 and II5.

[0044] ③ Move the other end of the aviation container pallet 13 to the connection position, adjust the posture of the aviation container pallet 13, and place the tie-down ring in the corresponding tie-down ring groove;

[0045] ④ Pull out the positioning pin 9 to move the positioning block I4 and positioning block II5 on the other side into the inner cavity of the adjacent sawtooth. After moving into place, insert the positioning pin 9 to lock the positioning block I4 and positioning block II5;

[0046] ⑤ Cover the cover plate 2, lock the lock 8 to the hook 22, and complete the installation of an aviation container pallet connection device 14;

[0047] ⑥ Repeat the above operation until the four aviation container pallet connection devices 14 are installed and the connection of the two container pallets 13 is completed.
