Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of mechanical manufacturing, and relates to a guide belt mechanism of a subsidence type aircraft arresting device. BACKGROUND

[0002] The aircraft arresting device is an important service facility of an airport, and is mainly used for arresting the aircraft that runs out of the runway due to accidental reasons, and plays an important role in ensuring the safety of the take-off and landing of the aircraft. After the aircraft hits the net, the net body is dragged to move forward, and the brake belt is pulled through the net belt connector. When the brake belt is pulled out, the energy absorber is rotated to generate resistance to arrest the aircraft.

[0003] One end of the brake belt is connected with the net body through the net belt connector, and the other end is connected with the energy absorber through the belt pin, and is coiled on the energy absorber belt disc at ordinary times. The conventional aircraft arresting device is installed on the ground, the energy absorber belt disc is flush with the ground level, and there is no height difference between the two ends of the brake belt, so that the brake belt can be smoothly drawn out of the energy absorber belt disc after the aircraft hits the net (such as Figure 1 ).

[0004] The subsidence type aircraft arresting device installed in the civil-military airport (such as Figure 2 ), because the energy absorber is installed in the tunnel below the ground surface, so that there is a height difference between the two ends of the brake belt, if it is directly connected in the previous way, when the aircraft hits the net and pulls the brake belt, the brake belt will be pulled out of the belt disc of the energy absorber, and the energy absorber cannot be rotated, and the energy absorber cannot generate the arresting force, and the whole aircraft arresting device will be invalid. It can be seen that the brake belt cannot be directly connected when there is a height difference between the two ends. In order to solve this problem, the guide belt mechanism of the subsidence type aircraft arresting device can effectively solve the problem that the brake belt is guided out of the energy absorber tunnel to the ground, so that the brake belt can be smoothly guided out when there is a height difference between the two ends, and the brake belt will not be pulled out of the brake disc, and the energy absorber can work normally. SUMMARY

[0005] The purpose of the present application is to provide a guide belt mechanism of a subsidence type aircraft arresting device, which can guide the brake belt out of the energy absorber tunnel to the ground, ensure the smooth guidance of the brake belt, and ensure the normal work of the energy absorber.

[0006] The technical scheme of the present application is as follows:

[0007] A guide belt mechanism of a subsidence type aircraft arresting device comprises a tunnel 2, a brake belt 3, a vertical shaft guide belt wheel 4, a first horizontal shaft guide belt wheel 5 and a second horizontal shaft guide belt wheel 6.

[0008] Vertical shaft guide pulley 4, Class I horizontal shaft guide pulley 5, and Class II horizontal shaft guide pulley 6 are all installed inside the tunnel 2. Class II horizontal shaft guide pulley 6 is flush with the ground plane 1. Brake band 3 passes vertically through vertical shaft guide pulley 4, then twists to be horizontal and passes through Class I horizontal shaft guide pulley 5. After that, brake band 3 is raised and passes horizontally through Class II horizontal shaft guide pulley 6. At this point, brake band 3 reaches the height of ground plane 1.

[0009] The vertical shaft guide pulley 4 includes a first top plate 7, a first rib plate 8, a first bottom plate 9, a first upright plate 10, a first support plate 11, a first guide pulley body 12, a first bearing 13, and a first guide pulley shaft 14. The first top plate 7, the first rib plate 8, the first bottom plate 9, and the first upright plate 10 form the overall frame of the vertical shaft guide pulley 4. The first top plate 7 and the first bottom plate 9 are connected by the first rib plate 8 and the first upright plate 10. The first support plate 11 is fixed on the first bottom plate 9. Two sets of vertical first guide pulley bodies 12 are installed on the first top plate 7 and the first support plate 11. The brake band 3 passes through the gap between the two sets of first guide pulley bodies 12. The first bearing 13 is embedded in the first guide pulley body 12. The first guide pulley shaft 14 passes through the inside of the first bearing 13. The first guide pulley body 12 rotates around the first guide pulley shaft 14.

[0010] The first-stage horizontal axis guide pulley 5 includes a guide rod 15, a second support plate 16, a second upright plate 17, a second base plate 18, a second rib plate 19, a second top plate 20, a second guide pulley body 21, a second guide pulley shaft 22, and a second bearing 23. The second upright plate 17, the second base plate 18, the second rib plate 19, and the second top plate 20 form the overall frame of the first-stage horizontal axis guide pulley 5. The second base plate 18 and the second top plate 20 are connected by the second upright plate 17 and the second rib plate 19. The second support plate 16 is fixed on the second base plate 18. There are two second upright plates 17, located at both ends of the overall frame. The guide rod 15 and the second guide pulley body 21 are horizontally installed between the two second upright plates 17. The brake band 3 passes through the gap between the guide rod 15 and the second guide pulley body 21. The second bearing 23 is embedded in the second guide pulley body 21, and the second guide pulley shaft 22 passes through the inside of the second bearing 23. The second guide pulley body 21 can rotate around the second guide pulley shaft 22.

[0011] Except for the absence of the guide rod 15, the Class II horizontal axis guide pulley 6 is the same as the Class I horizontal axis guide pulley 5.

[0012] The beneficial effects of this invention are as follows: The guide belt mechanism of this invention effectively solves the problem that the brake band cannot be properly connected in a sinking aircraft arresting gear due to the height difference between the two ends. By using this guide belt mechanism, the brake band can be smoothly guided from the energy absorber tunnel to the ground, ensuring the normal operation of the energy absorber and providing strong support for the deployment of sinking aircraft arresting gear in dual-use military and civilian airports.
