Description

Technical Field

[0001] The invention relates to the field of aircraft cargo loading, and in particular to an installation device for a standard container unit and a non-standard ground rail of a military aircraft floor. Background Art

[0002] In cargo aircraft, the air transport of container units is achieved by adding various limiting, guiding, mooring, and transmission devices to the floor rails. At present, the civil aviation cargo container units that have been qualified have formed standardization requirements. In order to adapt to the size of the pallet, the ground rails of civil aviation cargo aircraft all use a standard pitch of 25.4mm. However, the pitch of military transport aircraft is non-standard according to the use requirements. When these aircraft are loaded with civil aviation container units, due to the difference in size standards, the guide and limiting devices arranged around the pallet will have a lot of configurations, which is not convenient for the rapid configuration conversion of the aircraft. As a general aviation container unit, the British pallet is difficult to use on non-standard military aircraft, which reduces the utilization rate of the pallet.

[0003] Based on the standard pitch size and non-standard pitch size of military aircraft, a coordinated installation device is developed to reasonably distribute the imperial pallets on the metric ground track with the minimum product configuration, so as to effectively improve the aircraft's cargo capacity and enhance the compatibility of the pallets. Summary of the invention

[0004] The invention provides an installation device for a standard container unit and a non-standard ground rail of a military aircraft floor, which can solve the problems in the prior art of inconvenient installation and disassembly, inconvenient operation and reduced utilization of the cargo pallet.

[0005] The present invention provides an installation device for a standard container unit and a non-standard floor rail of a military aircraft floor, comprising a base, a first T-shaped column, a first telescopic column, a second telescopic column, an end cover, a pull ring, a rotating shaft, a linkage rod, a first compression spring, a second compression spring and a second T-shaped column, wherein one end of the base is fixedly connected to the first T-shaped column; the other end of the base is fixedly connected to the second T-shaped column; the first telescopic column and the second telescopic column are arranged on the base; the first compression spring is arranged inside the first telescopic column; the second compression spring is arranged inside the second telescopic column; the other ends of the first compression spring and the second compression spring are connected to the linkage rod; the other end of the linkage rod is connected to the rotating shaft; the other end of the rotating shaft is connected to the end cover; the end cover is provided with a pull ring; the first telescopic column, the second telescopic column, the first compression spring, the second compression spring and the linkage rod are fixed to the base through the end cover.

[0006] Preferably, the end cover is provided with a first groove and a second groove respectively adapted to the first telescopic column and the second telescopic column.

[0007] Preferably, one end of the base is fixedly connected to the first T-shaped column via a nut.

[0008] Preferably, the other end of the base is fixedly connected to the second T-shaped column through a nut.

[0009] Preferably, the bottom of each of the first telescopic column and the second telescopic column is provided with a third groove adapted to the linkage rod.

[0010] The present invention provides a device for installing a standard container unit and a non-standard ground rail of a military aircraft floor. During installation, the pull ring is manually pulled up counterclockwise, and the pull ring drives the linkage shaft and the linkage rod to move upward. The linkage rod drives the first telescopic column and the second telescopic column to move simultaneously. The pull ring is pulled up to a vertical position, and the first telescopic column and the second telescopic column are retracted into the base and flush with the base ground. Since the first telescopic column and the second telescopic column are provided with grooves that cooperate with the linkage rod at the bottom, when the linkage rod moves upward, the first telescopic column and the second telescopic column can be driven to move at the same time. When the linkage rod moves downward, it will not cause the movement of the first telescopic column and the second telescopic column. Both telescopic columns move downward under the action of their internal compression springs. The first T-shaped column and the second T-shaped column of the device are aligned with the circular hole (axis A) of the aircraft ground rail, and the device is embedded in the ground rail. After ensuring that the bottom surface of the base is in contact with the floor, it is translated forward by a quarter of the ground rail pitch. At this time, half of the cylindrical surface of the first T-shaped column and the second T-shaped column cooperates with the slide rail to achieve vertical limit movement, the first telescopic column is aligned with the circular groove of the ground rail (axis B), and the second telescopic column contacts the aircraft floor. Turn the pull ring clockwise, the linkage shaft and the linkage rod move downward, and disengage from the first telescopic column and the second telescopic column. Under the action of the first compression spring, the first telescopic column extends downward into the circular groove of the floor slide rail, and the second telescopic column is restricted by the floor and retained in the base, completing the installation of the first installation position of the device, which is relatively convenient to operate. Similarly, when installing another installation position, after the first T-shaped column and the second T-shaped column are embedded in the ground rail, the device is translated in the opposite direction to align the second telescopic column with the circular groove of the ground rail, and the second compression spring pushes the second telescopic column into the ground rail groove, and the first telescopic column contacts the aircraft floor and remains in the base. When disassembling the device, follow the reverse steps, which makes installation and disassembly more convenient. A first telescopic column and a second telescopic column are threadedly connected on the base. By adjusting the size between the two telescopic columns, the coordinated installation of the same configuration equipment in multiple positions when the civil standard container unit matches the non-standard size of the military aircraft can be achieved, effectively improving the cargo capacity of the aircraft and enhancing the compatibility of the pallet.

[0023] Preferably, the end cover 5 is provided with a first groove and a second groove respectively adapted to the first telescopic column 3 and the second telescopic column 4 .

[0024] Preferably, one end of the base 1 is fixedly connected to the first T-shaped column 2 via a nut.

[0026] Preferably, the bottom of each of the first telescopic column 3 and the second telescopic column 4 is provided with a third groove adapted to the linkage rod 8 .

[0027] Working principle: During installation, pull the pull ring 6 counterclockwise manually, the pull ring 6 drives the linkage shaft 7 and the linkage rod 8 to move upward, the linkage rod 8 drives the first telescopic column 3 and the second telescopic column 4 to move simultaneously, the pull ring 6 is pulled up to a vertical position, the first telescopic column 3 and the second telescopic column 4 are retracted into the base 1 and flush with the ground of the base 1. Since the first telescopic column 3 and the second telescopic column 4 are provided with grooves that match the linkage rod 8 at the bottom, when the linkage rod moves upward, it can drive the first telescopic column 3 and the second telescopic column 4 to move at the same time. When the linkage rod 8 moves downward, it will not cause the movement of the first telescopic column 3 and the second telescopic column 4. Both telescopic columns move downward under the action of their internal compression springs. Align the first T-shaped column 2 and the second T-shaped column 11 of the device with the circular hole (axis A) of the aircraft ground rail 20, and embed the device into the ground rail 20. After ensuring that the bottom surface of the base 1 is in contact with the floor, move forward by a quarter of the ground rail pitch. At this time, the first T-shaped column 2 and the second T-shaped column 11 both have half of the cylindrical surface matched with the slide rail to achieve vertical limit movement, the first telescopic column 3 is aligned with the circular groove of the ground rail (axis B), and the second telescopic column 4 is in contact with the aircraft floor. Turn the pull ring 6 clockwise, the linkage shaft 7 and the linkage rod 8 move downward, and disengage from the first telescopic column 3 and the second telescopic column 4. Under the action of the first compression spring 9, the first telescopic column 3 extends downward into the circular groove of the floor slide rail, and the second telescopic column 4 is restricted by the floor and retained in the base 1, completing the installation of the first installation position of the device, which is relatively convenient to operate. Similarly, when installing another installation position, after the first T-shaped column 2 and the second T-shaped column 11 are embedded in the ground rail, the device is translated in the opposite direction to align the second telescopic column 4 with the circular groove of the ground rail, and the second compression spring 10 pushes the second telescopic column 4 into the ground rail groove, and the first telescopic column 3 is in contact with the aircraft floor and retained in the base 1. When disassembling the device, the reverse steps are followed, which makes installation and disassembly more convenient. The first telescopic column 3 and the second telescopic column 4 are threadedly connected to the base 1. By adjusting the size between the two telescopic columns, the coordinated installation of the same configuration equipment in multiple positions when the civil standard container unit matches the non-standard size of the military aircraft can be achieved, effectively improving the cargo capacity of the aircraft and enhancing the compatibility of the cargo pallet.
