DETAILED DESCRIPTION

[0021] The following is combined with Figure 1-3 The specific implementation modes of the present utility model are further described in detail.

[0022] Depend on Figure 1-3The utility model provides an aviation automatic escalator passenger elevator car working platform, comprising a fixed platform 1, a bottom plate 2 is fixed at the bottom thereof, and the bottom plate 2 is used to be fixed at the upper end of the passenger elevator car;

[0023] The telescopic platform 3 is slidably arranged on the front upper surface of the fixed platform 1. When in use, the driver drives the passenger elevator to the cabin door position for disembarking passengers from the aircraft, brings the fixed platform 1 close to the cabin door, and then slides the telescopic platform 3 against the cabin door to reduce the gap between the fixed platform 1 and the cabin door, thereby preventing passengers from stepping on empty space and increasing safety;

[0024] The telescopic cylinder 4 is fixedly connected to the bottom plate 2, and the telescopic end of the telescopic cylinder 4 is fixedly connected to the telescopic platform 3. The telescopic platform 3 can be driven to slide and telescope by the telescopic cylinder 4.

[0025] The support mechanism 5 is arranged between the upper surface of the base plate 2 and the lower surface of the telescopic platform 3, and is used to increase the stability of the telescopic platform 3. In this embodiment, the support mechanism 5 is a telescopic structure, and the telescopic ends of the support mechanism 5 are respectively fixedly connected to the base plate 2 and the telescopic platform 3, and the upper and lower surfaces of the support mechanism 5 are respectively in sliding contact with the lower surface of the telescopic platform 3 and the upper surface of the base plate 2.

[0026] When the working platform of the automatic escalator passenger ladder for aviation of the utility model is used, the fixed platform 1 is first moved to a position close to the cabin door of the passenger plane, and then the telescopic platform 3 is extended by extending the telescopic oil cylinder 4 to reduce the gap between the fixed platform 1 and the cabin door. When the telescopic platform 3 is extended, the supporting mechanism 5 is lengthened and supported between the bottom plate 2 and the telescopic platform 3 by the supporting mechanism 5, thereby increasing the stability of the telescopic platform 3.

[0027] The support mechanism 5 includes a plurality of folding plates 51, the sides of which are hingedly connected, and the two outermost folding plates 51 are movably connected to the bottom plate 2 and the telescopic platform 3 respectively. When the telescopic platform 3 is extended, the support mechanism 5 is unfolded. The unfolded support mechanism 5 is similar to a wave-shaped structure with a large supporting range, which improves the firmness of the telescopic platform 3 and plays a good supporting role between the bottom plate 2 and the telescopic platform 3. When the telescopic platform 3 is folded, the support mechanism 5 can be folded to a large extent.

[0028] In some embodiments, the two outermost folding plates 51 are hingedly connected to two mounting plates 52 , and fixing bolts 53 are connected between the two mounting plates 52 and the bottom plate 2 and the telescopic platform 3 .

[0029] In order to reduce the friction between the folding plate 51 and the bottom plate 2 and the telescopic platform 3 , balls 54 are installed on the upper and lower surfaces of the folding plate 51 , and the balls 54 are in rolling contact with the upper surface of the bottom plate 2 and the lower surface of the telescopic platform 3 .

[0030] In order to further increase the stability of the telescopic platform 3 , a telescopic pipe 6 is fixed between the fixed platform 1 and the telescopic platform 3 .

[0031] A buffer rubber tube 7 is fixed to the front end of the telescopic platform 3 .

[0032] It is worth mentioning that the telescopic platform 3 is fixed with a first photoelectric proximity switch 8 and a second photoelectric proximity switch 9. The first photoelectric proximity switch 8 is used to detect the distance between the passenger elevator and the cabin door when the passenger elevator car approaches the cabin door, and remind the driver to stop the car in time. The second photoelectric proximity switch 9 is used to cut off the power supply of the telescopic cylinder 4 when the telescopic platform 3 approaches the cabin door, and stop the movement of the telescopic platform 3.

[0033] The working principle of the working platform of the passenger ladder car of the aviation automatic escalator of the utility model is as follows: first, the driver drives the passenger ladder car to the cabin door position for disembarking passengers from the aircraft, so that the fixed platform 1 is close to the cabin door, and then the telescopic platform 3 is driven to extend through the telescopic oil cylinder 4 to reduce the gap between the fixed platform 1 and the cabin door. In this process, the support mechanism 5 is automatically deployed to support the telescopic platform 3, and finally the stability of the telescopic platform 3 is increased to prevent passengers from stepping on empty space. When the telescopic platform 3 is retracted, the support mechanism 5 can be completely folded again without affecting the normal use of the working platform. Therefore, this design not only ensures the stability of the working platform, but also improves the safety of passengers.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
