DETAILED DESCRIPTION

[0018] The following is combined with Figure 1-2 The specific implementation modes of the present utility model are further described in detail.

[0019] Depend on Figure 1-2The utility model is an aviation escalator, comprising a ladder body 1, a frame 3 installed at the lower end of the ladder body 1 for connecting with a vehicle 2, a rotating shaft 4 connected between the frame 3 and the rear end of the vehicle 2, and a lifting cylinder 5 connected between the frame 3 and the vehicle 2 for lifting the frame 3. When in use, the driver drives the vehicle 2 close to the aircraft, and then lifts the ladder body 1 of the escalator through the lifting cylinder 5, so that the upper platform of the ladder body 1 and the cabin door are connected. The above is the prior art and will not be repeated here. On the basis of the prior art, the utility model aviation escalator also includes

[0020] The auxiliary support mechanism 6 is supported at the front end of the ladder body 1 to increase the stability of the front end of the ladder body 1, and the auxiliary support mechanism 6 includes a support rod 61, the upper end of the support rod 61 is rotatably connected to the ladder body 1, and the lower end of the support rod 61 is installed with a support wheel 62, and the ladder body 1 is installed with a power mechanism 7 for driving the upper end of the support rod 61 to rotate. When not in use, the support rod 61 is in a folded state. When in use, the support rod 61 is unfolded by the power mechanism 7 so that the support wheel 62 of the support rod 61 is supported on the road surface, thereby increasing the stability of the ladder body 1 when the ladder body 1 is lifted by the lifting cylinder 5.

[0021] In some embodiments, the support wheel 62 is a universal wheel structure.

[0022] The power mechanism 7 includes an expansion cylinder 71, one end of which is rotatably connected to the ladder body 1, and the other end of the expansion cylinder 71 is rotatably connected to the side of the support rod 61. When the expansion cylinder 71 is extended, it can drive the support rod 61 to rotate and expand, and when the expansion cylinder 71 is shortened, it can drive the support rod 61 to rotate and close.

[0023] In order to further improve the closing effect of the support rod 61, the connection end between the deployment cylinder 71 and the ladder body 1 is a sliding connection, the ladder body 1 is fixedly installed with a booster cylinder 72, and the head of the booster cylinder 72 is fixed with a booster slider 73.

In this way, when folding the support rod 61, the support rod 61 can be folded in one section by shortening the deployment cylinder 71, and then the booster cylinder 72 is shortened, which can drive the other end of the deployment cylinder 71 connected to the support rod 61 to slide far away, thereby realizing two-stage folding.
