Description

Technical Field

[0001] The utility model belongs to the technical field of passenger boarding ladders, and in particular relates to a device for automatically sensing the distance to an aircraft for a passenger boarding ladder. Background Art

[0002] Passenger boarding ladder is a special equipment for airports to provide passengers with boarding and disembarking. It consists of a car chassis or a self-made chassis, a telescopic ladder, a telescopic and pitching mechanism, a telescopic platform, a ladder side plate and a support foot. In recent years, with the large-scale application of carbon fiber epoxy composite materials in new generation passenger aircraft for lightweight design, reduced emissions and increased range, the impact resistance of the fuselage made of composite materials has been greatly reduced, and the requirements for aircraft docking are higher; at the same time, with the vigorous development of the aviation industry, the annual throughput of various airports has increased year by year, and the demand for ground support and services for passenger boarding ladders has also increased. The existing passenger ladder car-to-aircraft platforms are mostly in three forms: fixed platform, passive rotating swing buffer platform and single-acting cylinder telescopic platform; among them, the fixed platform has extremely high requirements for the driver for aircraft operation and is prone to aircraft collision accidents; although the rotating swing platform has the function of contact rotation and swing to avoid excessive collision.

[0003] However, when the existing passenger boarding stairs are moved to the aircraft body, it is often necessary to control the passenger boarding stairs to be close to the aircraft disembarkation gate. In actual operation, the passenger boarding stairs may collide with the aircraft body and scratch the outer coating of the aircraft. In addition, when the boarding platform moves to a certain distance, the distance between the boarding platform and the aircraft body cannot be detected.

[0004] In view of this, the present utility model is proposed. Utility Model Content

When the boarding ladder body 1 moves to a certain position, the circular rubber pad 3 and the rectangular plug rod 5 will be able to contact the aircraft body, so the force can cause the circular rubber pad 3 to shrink, thereby to a certain extent ensuring that the boarding ladder body 1 and the aircraft body are prevented from colliding; when the rectangular plug rod 5 moves, it can drive the rectangular limit plate 13 and the rectangular mounting plate 14 to slide in the rectangular groove 11 opened in the rectangular connecting rod 7, so that the reset spring 12 can be compressed. When the rectangular mounting plate 14 moves, it can squeeze the knocking rod 10 to flip with the assistance of the rotating rod 16 and the bearing 15. Therefore, the knocking rod 10 can knock with the knocking plate 8 installed in the rectangular groove 6, thereby generating a sound. The sound generated at this time can be transmitted from the sound outlet 2 to remind nearby staff, so that the effect of automatic perception can be achieved.

[0027] In a specific embodiment, two groups of equally spaced sound outlet holes 2 are provided on one side wall of the inner cavity of the two rectangular slots 6. In this configuration, the positions of the sound outlet holes 2 are determined.

[0028] Further, the reset mechanism includes two reset springs 12, which are respectively arranged in the inner cavities of the two rectangular grooves 11, one end of the two reset springs 12 is fixedly connected to the inner wall of the rectangular groove 11, and the other end of the two reset springs 12 is fixedly connected to a rectangular mounting plate 14, and the two rectangular mounting plates 14 are respectively fixedly installed with a rectangular limit plate 13 at one end away from the reset spring 12, and the two rectangular limit plates 13 are fixedly installed with a rectangular plug rod 5 at one end away from the rectangular mounting plate 14. In this configuration, the installation position and components of the reset mechanism are determined.

[0029] Furthermore, the two rectangular limiting plates 13 are both arranged in the inner cavity of the rectangular groove 11, and the two rectangular limiting plates 13 are respectively slidably connected to the inner wall of the rectangular groove 11. In this arrangement, it is ensured that the rectangular limiting plates 13 can slide in the rectangular groove 11.

[0030] Further, the knocking mechanism includes a plurality of knocking rods 10, each of which is respectively arranged in the inner cavity of the installation slot 9, each of which is symmetrical with each other, each of which is fixedly mounted with a rotating rod 16, each of which is provided with a bearing 15 at both ends, and each of which is respectively mounted on the inner wall of the installation slot 9. In this configuration, the installation position and components of the knocking mechanism are determined.

[0031] Furthermore, each rotating rod 16 is provided with two mutually symmetrical torsion springs 17, and the two ends of the two torsion springs 17 are respectively provided on the bearing 15 and the knocking rod 10, and the two ends of each knocking rod 10 are respectively in contact with the rectangular mounting plate 14 and the knocking plate 8. In this arrangement, it is ensured that when the rectangular mounting plate 14 moves, it can squeeze the knocking rod 10 to turn over with the assistance of the rotating rod 16 and the bearing 15.

[0032] The implementation principle of the automatic sensing device for the distance between the passenger boarding ladder and the aircraft in this embodiment is as follows:

[0033] First, the staff moves the boarding ladder body 1 close to the aircraft door through the boarding vehicle. When the boarding ladder body 1 moves to a certain position, the circular rubber pad 3 and the rectangular plug rod 5 can contact the aircraft body. Therefore, the force can make the circular rubber pad 3 shrink, thereby ensuring to a certain extent that the boarding ladder body 1 and the aircraft body are prevented from colliding.

[0034] At the same time, when the rectangular plug-in rod 5 moves, it can drive the rectangular limiting plate 13 and the rectangular mounting plate 14 to slide in the rectangular groove 11 opened in the rectangular connecting rod 7, so that the reset spring 12 can be compressed. When the rectangular mounting plate 14 moves, it can squeeze the knocking rod 10 to flip with the assistance of the rotating rod 16 and the bearing 15. Therefore, the knocking rod 10 can knock with the knocking plate 8 installed in the rectangular groove 6, thereby generating a sound. The sound generated at this time can be transmitted from the sound outlet 2 to remind nearby staff, so that the effect of automatic perception can be achieved.
